In the cellular phone 101, the upper casing 90 and the lower casing 91 are completely laid on the plane, and the upper casing 90 is slid upward (arrow P direction) with respect to the lower casing 91. By doing so, the user can use it as a mobile phone. The upper housing 90 is configured to be used in a state where it is rotated 90 ° counterclockwise from the state shown in FIG. 1 (see FIG. 3).

  Further, as shown in FIG. 1, the upper casing 90 of the mobile phone 101 includes a display unit 10 composed of a liquid crystal screen provided on the front side (front side of the paper) and a plurality of units disposed below the display unit 10. And an audio output unit 30 that is arranged above the display unit 10 and outputs the voice of the other party. In addition, the lower housing 91 is provided with an input unit 21 composed of a plurality of buttons arranged so as to be exposed when sliding, and a voice input unit 40 that collects a user's voice and the like. Further, the headphone 50 can be connected to the side of the lower housing 91 with a terminal. Further, as shown in FIG. 2, a control circuit unit 60 for the mobile phone 101 to perform various processes as a terminal device is built in the lower housing 91 (see FIG. 1).

  As shown in FIG. 1, the input unit 20 cancels (returns) the input operation to the menu button 20a, the call button 20b, the mail activation button 20c, the selection operation button 20d including a cross key, and the input operation. Clear button 20e. The input unit 21 includes a plurality of (12) input numeric keys 21a for inputting a telephone number when making a call or inputting characters when creating a mail.

  As shown in FIG. 2, the control circuit unit 60 includes a control unit 61 composed of a CPU that supervises control processing, a telephone communication unit 62 that performs wireless communication as a normal mobile phone, and other mobile phones. An infrared communication unit 63 and a wireless communication unit 64 that perform communication processing by a method different from normal telephone communication, and a ROM (read only storage device) 65 in which a control program executable by the control unit 61 is stored It is constituted by a flash ROM (nonvolatile ROM memory) 66 capable of storing temporary data generated at the time of control and content data 70 composed of a digital moving image including audio or a still image. Further, the control circuit unit 60 is electrically connected to the display unit 10, the input units 20 and 21, the audio output unit 30, and the audio input unit 40 via the control unit 61. The wireless communication unit 64 is an example of the “first communication unit” in the present invention, and the infrared communication unit 63 is an example of the “second communication unit” in the present invention. The flash ROM 66 is an example of the “storage unit” in the present invention.

  Therefore, the mobile phone 101 is configured to be able to reproduce the content data 70 stored in the flash ROM 66 while being output to the display unit 10 and the audio output unit 30 by the control unit 61. In addition, when the user connects the headphones 50, the sound is transmitted to the user via the headphones 50.

  Here, in the first embodiment, as shown in FIG. 3, the mobile phone 101 can interact with each of the other mobile phones 102, 103, and 104 by causing the wireless communication unit 64 to function. To form an ad hoc network. This ad hoc network is a form in which a plurality of terminal stations are connected to each other without intervening access points while using wireless communication technology such as IEEE802.11x standard or Bluetooth standard widely used for wireless connection such as computers. Multi-hop communication). Therefore, the mobile phones 101 to 104 can be connected to a simple network in a place where a base station or an access point is not established by an ad hoc network (for example, in a limited area such as a bus or train or a park open space). It can be formed. In the present invention, it is assumed that the mobile phones 102, 103, and 104 have the same configuration as the mobile phone 101 described above. The ad hoc network is an example of the “small group” in the present invention, and the mobile phones 102, 103, and 104 are examples of the “other mobile terminal device” in the present invention. In the first embodiment, the user who owns the mobile phone 101 corresponds to the “first user” of the present invention, and the user who owns each of the mobile phones 102 to 104 corresponds to the “second user” of the present invention. The description will be made assuming a state corresponding to "."

  Therefore, when the mobile phones 101 to 104 form an ad hoc network, for example, as shown in FIG. 3, the content data 70 owned by the mobile phone 101 is wirelessly communicated to each of the other mobile phones 102, 103, and 104. By distributing via the unit 64 (see FIG. 2), each of the four mobile phones 101 to 104 is configured to be able to reproduce the same content data 70 after distribution of the content data 70. .

  In the first embodiment, when forming an ad hoc network for reproducing the same content data 70 in the four mobile phones 101 to 104, the infrared communication unit 63 (see FIG. 2) to transmit to each of the other mobile phones 102, 103, and 104 in advance. Here, the device ID of the mobile phone 101 may be, for example, a physical address or a telephone number of the mobile phone 101, a name registered by the user in the mobile phone 101, or the like. The information that can be identified with the mobile phone is shown. Then, as shown in FIG. 4, for example, by operating the menu button 20a and the selection operation button 20d in the mobile phones 101 and 102, each mobile phone is switched to the “group formation mode” via the setting screen 81. After that, as shown in FIG. 5, by pressing the selection operation button 20d with each infrared communication unit 63 facing each other at an interval of about 5 cm to about 15 cm, an ad hoc network is formed by infrared communication. The device ID and time information of the telephone 101 are configured to be transferred to the mobile phone 102. At this time, the device ID of the mobile phone 102 is also transmitted from the mobile phone 102 to the mobile phone 101. Thus, the mobile phones 101 and 102 are configured to recognize that they are members of a small group. The group formation mode is an example of the “operation mode for forming a small group” in the present invention.

  In the first embodiment, when forming an ad hoc network, the mobile phone 102 that has already formed the network is in the above-described “group formation mode” state with respect to the mobile phones 103 and 104 that have not yet formed the network. The device ID and time information (“master time” to be described later) possessed by the mobile phone 101 and the device ID of the mobile phone 102 are sequentially transferred. Note that the mobile phone 101 is configured to start counting the time information (master time) described above immediately after switching to the “group formation mode”. Then, when the mobile phone 101 establishes an ad hoc network with another mobile phone, the mobile phone 101 transmits the time information that has been started at the time of establishing the ad hoc network to the other mobile phone. It is configured. In addition, the other mobile phones (102 to 104) that have received the time information that has been started are configured to start counting from the received time information. In this way, the mobile phone 101 to 104 is configured to form an ad hoc network and share time information for simultaneously reproducing the content data 70.

  In the first embodiment, as shown in FIG. 5, after the ad hoc network is formed, the content data 70 owned by the mobile phone 101 is distributed to the mobile phones 102 to 104 via the wireless communication unit 64. It is configured. Then, when reproducing the content data 70 distributed from the cellular phone 101, each of the cellular phones 102 to 104 reproduces the content data 70 in synchronization with the timing at which the cellular phone 101 reproduces the content data 70 based on this time information. It is configured to be able to do. In this way, the user who owns each mobile phone connected by the ad hoc network can see the visual and audio output unit 30 (headphone 50) from the display unit 10 in each mobile phone (101, 102, 103, and 104). It is possible to view the common content data 70 at the same time through the auditory sense. Note that both the time information of the mobile phone 101 and the time information received from the mobile phone 101 by each of the mobile phones 102 to 104 correspond to an example of “time information for reproducing content data” of the present invention. doing.

  Here, while the mobile phones 101 to 104 are simultaneously reproducing the same content data 70 in an ad hoc network environment, the user of one of the mobile phones (for example, the mobile phone 101) It is assumed that the user wants to view the scene after viewing again by rewinding to an arbitrary time. In the first embodiment, the content data 70 can be viewed from the rewinded state simultaneously on other mobile phones based on the user's operation for performing rewind playback. Even in such a case, it is possible to reproduce the content data 70 rewound to the same position (reproduction time) at the same timing based on the time information by sharing the time information between the mobile phones. Become. In addition, regarding the above-mentioned “batch rewinding operation”, before performing rewinding, a communication for inquiring whether or not a user who wants to perform a rewinding operation can perform a batch rewinding operation to another user is a wireless communication. It is configured to be performed via the unit 64. In this case, it is preferable that the “simultaneous rewinding operation” is executed after receiving a permission signal permitting the simultaneous rewinding operation from all other users.

  In the first embodiment, each of the mobile phones 101 to 104 has a predetermined user ID even when the mobile phones 101 to 104 are simultaneously playing the same content data 70 in an ad hoc network environment. By performing this key operation (for example, an operation of pressing the clear button 20e (see FIG. 1), etc.), it is possible to temporarily exit from the simultaneous playback mode. In this case, a user who has left the simultaneous playback mode can perform rewind playback of the content data 70 on his / her mobile phone regardless of the viewing status of other users. Note that the user who has temporarily exited the simultaneous playback mode again returns to the simultaneous playback mode by performing a predetermined key operation (for example, an operation of pressing the clear button 20e (see FIG. 1) again). It is configured as follows. Even in such a case, the playback operation based on the shared time information is executed, so that the user who has returned to the simultaneous playback mode can view the content data 70 from the scene being played back simultaneously on another mobile phone. It is configured.

  In the first embodiment, when the content data 70 is played back simultaneously, as shown in FIG. 6, the display unit 10 of the mobile phone 101 has a moving picture display area 11 for displaying the played video (video content). The communication display areas 12a to 12d (shown in a broken line frame) provided at the four corners of the moving image display area 11 are arranged. In the four communication display areas 12a to 12d, character images 1 to 4 (in the first embodiment, associating each user) of members (users of the mobile phones 101, 102, 103, and 104) constituting the ad hoc network. A portrait image that can be specified or specified) is displayed. Here, the user of the mobile phone 101 is displayed as a character image 1 composed of a still image in the communication display area 12a, and the user of the mobile phone 102 is displayed as a character image 2 composed of a still image in the communication display area 12b. The Similarly, the user of the mobile phone 103 is displayed as the character image 3 consisting of a still image in the communication display area 12c, and the user of the mobile phone 104 is displayed as the character image 4 consisting of a still image in the communication display area 12d. The

  Moreover, the character image 1 (2-4) is comprised by several image data for expressing a user's emotion. Further, the character images 1 (2 to 4) made up of a plurality of image data are configured to be set in advance by a user operation. The character image 1 is an example of the “first image data” in the present invention, and the character images 2 to 4 are examples of the “second image data” in the present invention.

  That is, as shown in FIG. 7, for example, after the mobile phone 101 is switched to the “communication function setting mode” via the setting screen 82 by operating the menu button 20 a and the selection operation button 20 d in the mobile phone 101. A plurality of character images 1 (images 1a to 1d) can be created with reference to a setting screen 83 as shown in FIG.

  As illustrated in FIG. 8, the character image 1 will be described as an example. On the setting screen 83, images 1 a to 1 d corresponding to various emotions such as emotions of the user of the mobile phone 101 can be set by the user. It is comprised so that. Here, the image 1a is an image having an expression expressing the user's “happiness” emotion, and the image 1b is set to an image having an expression expressing the user's “anger” emotion. . Further, the image 1c is an image having an expression expressing the user's “sadness” emotion, and the image 1d is set to an image having an expression expressing the user's “fun” emotion. . As for character images 2 to 4 (see FIG. 6), images similar to the images 1a to 1d described above are preliminarily displayed on each mobile phone in accordance with emotions such as emotions of each user. It is configured to be configurable. The images 1a to 1d are examples of the “first image data” in the present invention. Here, various methods can be considered as a method of creating the images 1a to 1d. For example, image data acquired from a website such as the Internet through a predetermined procedure for a fee or free of charge may be used, or image data is created using image creation software provided in advance in the mobile phone 101 or the like. You may do it.

  Further, as shown in FIG. 8, each of the images 1a to 1d is configured to correspond to an input numeric keypad 21a. That is, in the first embodiment, when the user presses the “2” button of the input numeric keypad 21a, the image 1a (feeling of happiness) is displayed in the communication display area 12a (see FIG. 6) and “6” When the “” button is pressed, an image 1 b (anger emotion) is displayed in the communication display area 12 a. Similarly, when the user presses the “8” button, the image 1c (sad feelings) is displayed, and when the user presses the “4” button, the image 1d (fun feelings) is displayed. Has been. The character image 1 (images 1a to 1d) once displayed is configured to disappear (switch to a non-display state) from the communication display area 12a after a predetermined time has elapsed (for example, after about 2 seconds). The plurality of input numeric keys 21a correspond to “reaction buttons” in the control operation of the cellular phone 101 described later, and the input numeric keys 21a are recognized by the user as reaction buttons at the time of simultaneous reproduction.

  Further, as shown in FIG. 8, each of the images 1 a to 1 d is configured such that a comment sentence 5 (5 a to 5 d) for expressing emotions in characters can be set by the user. That is, the comment sentence 5a used when expressing happiness corresponds to the image 1a, and the comment sentence 5b used when expressing anger corresponds to the image 1b. Further, the image 1c corresponds to a comment sentence 5c used when expressing sadness, and the image 1d is configured to correspond to a comment sentence 5d used when expressing fun. Accordingly, in the first embodiment, when the user of the mobile phone 101 presses the “2” button, the comment sentence 5a is displayed in a balloon state in the vicinity of the communication display area 12a (see FIG. 6) together with the image 1a. At the same time, when the “6” button is pressed, the comment sentence 5b is displayed in a state of being blown out in the vicinity of the communication display area 12b together with the image 1b. Similarly, when the user of the mobile phone 101 presses the “8” button, the comment sentence 5 c is displayed together with the image 1 c, and when the “4” button is pressed, the comment sentence 5 d is displayed together with the image 1 d. Has been. The comment sentences 5a to 5d are examples of the “first character comment data” in the present invention.

  Therefore, in the first embodiment, as shown in FIG. 6, when the content data 70 is played back simultaneously between the mobile phones 101 to 104 (state of FIG. 3), the user of the mobile phone 101 By depressing the corresponding input numeric keypad 21a according to 70 scenes, it is possible to send (post) own comment information (impressions and opinions in the scene) to the communication display area 12a. At this time, the comment information (character image 1 and comment sentence 5) transmitted by the user is transmitted to each of the mobile phones 102 to 104 via the wireless communication unit 64. Thereby, the users of the mobile phones 102 to 104 are configured to be able to view the comment information of the user of the mobile phone 101 with respect to the content data 70 being viewed through the display unit 10 of each mobile phone.

  Moreover, in 1st Embodiment, the delivery operation | movement of the comment information by the wireless communication part 64 toward the other user from the user of the mobile telephone 101 mentioned above is comprised so that it may mutually perform between mobile telephones. That is, comment information (character image 2 and corresponding comment text) of the user of the mobile phone 102 is distributed to the mobile phones 101, 103, and 104, and comment information (character image 3 and Corresponding comment text) is distributed to the mobile phones 101, 102 and 104. Similarly, comment information (character image 4 and corresponding comment text) of the user of the mobile phone 104 is distributed to the mobile phones 101, 102, and 103. In the first embodiment, the comment information (character image 1 and comment sentence 5) of the user who owns the mobile phone 101 corresponds to the “first comment information” of the present invention and each of the mobile phones 102 to 104. The comment information of the user who owns the character image (the comment image corresponding to each of the character image 2, 3 or 4 and the character image 2, 3 or 4) corresponds to the “second comment information” of the present invention. As a result, during the simultaneous playback of the content data 70 between the mobile phones 101 to 104, each user can communicate each other's impressions according to the scene of the content data 70 being played back. It is configured to be. Therefore, an ad hoc network is formed in the public (such as in a train or a bus) even when the mobile phones 102 to 104 are physically separated from each other or even though they are close to each other. Even when each user views with the headphones 50 worn, the users who view the content data 70 reproduced at the same time actively use the above-described character images and comment sentences. It is configured to enable easy communication.

  In the first embodiment, as shown in FIG. 9, a plurality of images are further set in each of the images 1 a to 1 d representing the emotion of the user of the mobile phone 101 according to the degree of each corresponding emotion. It is comprised so that. In other words, the image 1b (an image expressing anger emotion) will be described as an example. On the setting screen 84, an image composed of a still image corresponding to the degree (strength / weakness) of the anger emotion possessed by the user of the mobile phone 101. 11b, 21b, 31b, 41b and 51b (five levels) can be set. In addition, each image (images 11b to 51b) is configured such that the image displayed in the communication display area 12a is switched in stages according to the length of time for which the “6” button is pressed.

  Specifically, when the “6” button is lightly pressed once, the image 11b (slightly angry expression) is selected and displayed in the communication display area 12a, while the “6” button is pressed for about 2 seconds. When pressed continuously, the image 31b (ordinarily angry expression) is selected and displayed in the communication display area 12a. Similarly, when the “6” button is pressed for about 3 seconds, the image 51b (an extremely strong and angry expression) is selected and displayed in the communication display area 12a. Here, the image 31b shown in FIG. 9 is displayed as a representative image of the angry character image (image 1b) on the screen shown in FIG. The images 11b to 51b are an example of the “first image data” in the present invention.

  Further, as shown in FIG. 9, each of the images 11b to 51b corresponds to comment sentences 15b, 25b, 35b, 45b, and 55b for expressing the degree of anger feeling (strength and weakness) in characters. It is configured as follows. As a result, when the user of the mobile phone 101 selects the length of time for which the button “6” is pressed, any one of the images 11b to 51b and the corresponding comment text (comment text 15b to 55b) are displayed. It is configured to be displayed in a balloon state in the vicinity of the communication display area 12a. Here, the comment sentence 35b is configured to be displayed corresponding to the comment sentence 5b shown in FIG. 8 so that the above-described image 31b corresponds to the image 1b (see FIG. 8). The comment sentences 15b to 55b are examples of the “first character comment data” in the present invention.

  9 shows an example in which images 11b to 51b and comment sentences 15b to 55b are set according to the degree of anger for the image 1b (see FIG. 8) expressing the anger emotion. In addition to the emotions of happiness (image 1a), sadness (image 1c), and enjoyment (image 1d), images and comment sentences can be set according to the degree of each emotion. Has been. In the first embodiment, four emotions of emotion, emotion, degree of each emotion, five stages = 20 character images 1 (see FIG. 6), and 20 comment texts corresponding to 20 character images 1 respectively. 5 (see FIG. 6) can be set by the user.

  In the first embodiment, the character image 1 and the comment sentence 5 set in advance by a user operation are stored in the flash ROM 66 when the “communication function setting mode” shown in FIG. Has been. Further, the character image 1 and the comment sentence 5 stored in the flash ROM 66 can be edited and set again at another opportunity.

  In the first embodiment, the comment information (character image 1 and comment sentence 5) transmitted by the user of the mobile phone 101 during the simultaneous reproduction of the content data 70 between the mobile phones 101 to 104 is time information. At the same time, it is configured to be stored in the flash ROM 66 of each mobile phone. Similarly, individual comment information (character image and comment text) transmitted by each user of the mobile phones 102 to 104 is also stored in the flash ROM 66 of each mobile phone together with time information. Here, the character image included in the comment information transmitted from each user of the mobile phones 102 to 104 corresponds to the “second image data” of the present invention, and the comment transmitted from each user of the mobile phones 201 to 104. The comment text included in the information corresponds to “second character comment data” of the present invention.

  In the first embodiment, the comment information (character image and comment text) transmitted by each user stored in the flash ROM 66 is displayed at another time such as after the simultaneous reproduction of the content data 70. The mobile phone can be played together with the content data 70. That is, each user is configured to be able to look back (confirm) the state of other users' reactions with respect to the content data 70 including their own reactions.

  Next, with reference to FIG. 5 and FIG. 10 to FIG. 12, a control flow for simultaneously reproducing content data between mobile phones in which an ad hoc network is formed in the first embodiment will be described.

  First, referring to FIG. 10, a control operation when two mobile phones 101 and 102 form an ad hoc network for simultaneously reproducing content data will be described. In the following description, first, a case will be described in which communication is performed from the mobile phone 101 side to the mobile phone 102 after a signal in each control step is generated from the mobile phone 101 side.

  First, in step S1, it is determined whether or not the user of the mobile phone 101 has switched to the “group formation mode” for forming an ad hoc network via the setting screen 81 shown in FIG. This determination is repeated until the mobile phone 101 is switched to the “group formation mode”. If it is determined in step S1 that the mode has been switched to the “group formation mode”, the “group formation mode” for forming the ad hoc network is activated. Thereafter, in step S <b> 2, in the mobile phone 101, the “infrared communication mode” is switched to the ON state by the control unit 61. In step S <b> 3, the control unit 61 starts counting “master time”.

  Next, in step S4, the control unit 61 (see FIG. 5) determines whether or not a communication button (for example, a selection operation button 20d) for forming a network has been pressed by the user of the mobile phone 101. At the same time, this determination is repeated until the communication button is pressed. If it is determined in step S4 that the communication button has been pressed, in step S5, infrared communication for forming an ad hoc network is performed by the infrared communication unit 63 (see FIG. 5) with respect to the mobile phone 102.

  That is, in step S5, the “master time” and the device ID are transmitted from the mobile phone 101 to the mobile phone 102 by the control unit 61 (see FIG. 5). This “master time” indicates time information for simultaneously reproducing the content data 70 between the mobile phones 101 and 102, and is an example of “time information for reproducing the content data” of the present invention. It corresponds to.

  Note that the mobile phone 101 starts counting the “master time” it has when it shifts to the “group formation mode” in step S3. In addition, the “master time” transmitted to the mobile phone 102 in step S5 is the time at which transmission from the mobile phone 101 to the mobile phone 102 is started after the “master time” is counted in the mobile phone 101. Information (counted “master time”) is included.

  In the mobile phone 102, the control unit 61 (see FIG. 5) determines in step S21 whether or not the user of the mobile phone 102 has switched to the “group formation mode” for forming an ad hoc network. This determination is repeated until the mobile phone 102 is switched to the “group formation mode”. If it is determined in step S21 that the mode has been switched to the “group formation mode”, the “group formation mode” for forming the ad hoc network is activated. Thereafter, in step S <b> 22, in the mobile phone 102, the “infrared communication mode” is switched to the ON state by the control unit 61.

  In step S23, it is determined whether the device ID transmitted from the mobile phone 101 and the “master time” after the start of counting are received via the infrared communication unit 63 (see FIG. 5). This determination is repeated until the device ID and “master time” transmitted from 101 are received. If it is determined in step S <b> 23 that the device ID and “master time” have been received, an ad hoc network is formed between the mobile phone 102 and the mobile phone 101. As a result, the mobile phone 102 starts counting from the received “master time”. Thereafter, in step S24, the device ID of the mobile phone 101 is stored in the flash ROM 66 of the mobile phone 102.

  Here, when the two mobile phones perform the above-described infrared communication with each other, an action of bringing the infrared rays such as the side surface and the back surface of the mobile phone close to each other is performed by both users. That is, the two mobile phones 101 and 102 may approach to a distance where infrared communication is possible, or may be lightly touched (touched) during communication. In this way, since two mobile phones used at physically separated locations undergo an act of physically approaching or contacting each other when forming an ad hoc network, both users can It will be possible to feel more directly that we will join the group and communicate.

  Thereafter, in step S <b> 25, the mobile phone 102 transmits the device ID of the mobile phone 102 to the mobile phone 101. As a result, the mobile phone 102 recognizes that an ad hoc network has been established with the mobile phone 101, and ends both the “group formation mode” and the “infrared communication mode” (OFF state) in step S26. .

  Thus, in step S6, the mobile phone 101 determines whether or not the device ID transmitted from the mobile phone 102 has been received by the control unit 61 (see FIG. 5) and receives the device ID of the mobile phone 102. The judgment is repeated until If it is determined in step S6 that the device ID transmitted from the mobile phone 102 has been received, the mobile phone 101 recognizes that an ad hoc network has been established with the mobile phone 102, and in step S7, Both “group formation mode” and “infrared communication mode” are ended (OFF state).

  At this point, the mobile phones 101 and 102 recognize that they are members of a small group through the exchanged device IDs, and share a “master time” in which counting proceeds at the same time.

  Next, in step S9 in the mobile phone 101, it is determined whether or not the content data 70 has been selected by the user of the mobile phone 101, and this determination is repeated until the content data 70 is selected. If it is determined in step S9 that the content data 70 has been selected, the selected content data 70 is transmitted to the mobile phone 102 in step S10.

  In step S27 in the mobile phone 102, it is determined whether or not the content data 70 transmitted from the mobile phone 101 is received, and this determination is repeated until the content data 70 transmitted from the mobile phone 101 is received. It is. If it is determined in step S27 that the content data 70 has been received, the mobile phone 102 stores the received content data 70 in the flash ROM 66 in step S28.

  In step S11 of the mobile phone 101, it is determined whether or not a button operation for reproducing the content data 70 (a pressing operation of the selection operation button 20d) is performed by the user of the mobile phone 101, and the content data This determination is repeated until a button operation for reproducing 70 is performed. If it is determined in step S11 that a button operation (pressing operation of the selection operation button 20d) has been performed, reproduction of the selected content data 70 is started in step S12. As a result, the user of the mobile phone 101 starts viewing the content data 70 via the display unit 10. In step S 13, the mobile phone 101 transmits a “command signal” for reproducing the content data 70 and a “master time” for transmitting the command signal to the mobile phone 102.

  In step S29 in the mobile phone 102, the “command signal” for reproducing the content data 70 transmitted from the mobile phone 101 and the “master time” in which the time for transmitting the command signal is recorded are received. This determination is repeated until the “command signal” and “master time” are received. If it is determined in step S29 that the “command signal” and “master time” transmitted from the mobile phone 101 have been received, reproduction of the received content data 70 is started in step S30. At this time, in the mobile phone 102, only the time difference between the “master time” being counted by the mobile phone 102 and the “master time” received from the mobile phone 101 in step S29 (master time when the mobile phone 101 sends a command). The reproduction of the content data 70 is started from the reproduction time corresponding to the point of time when the “master time” of the self is advanced. That is, the mobile phone 102 starts playback from the middle of the content data 70 while skipping the playback point by the time lag between the playback operation (step S12) by the user of the mobile phone 101 and the subsequent transmission operation (step S13). It will be. As a result, the user of the mobile phone 102 starts viewing the content data 70 in a state of being synchronized with the mobile phone 101 via the display unit 10.

  In this way, the two mobile phones 101 and 102 simultaneously reproduce the content data 70 at substantially the same timing in a state where an ad hoc network is formed. In the above, the control flow between the mobile phone 101 and the mobile phone 102 has been described. However, an ad hoc network is established between mobile phones by performing the same control as described above between other mobile phones. The content data 70 is simultaneously reproduced in the formed state.

  In addition, when an ad hoc network is formed between four mobile phones and the content data 70 is simultaneously played back, the content data after the content data owned by the mobile phone 101 is distributed to the other mobile phones 102 to 104 as described above It is also possible to perform simultaneous playback of these, or to distribute different content data from a mobile phone other than the mobile phone 101 to another mobile phone for simultaneous playback. In this case, based on the registration of each device ID exchanged when forming an ad hoc network, the content data distribution source (parent device) and the content data reception destination (child device) are distinguished. Therefore, mutual management in an ad hoc network environment can be realized by appropriately managing the relationship between the distribution source (master unit) and the reception destination (slave unit) using the device ID.

  Next, with reference to FIGS. 5 and 11, a control operation related to communication between users when the two mobile phones 101 and 102 simultaneously reproduce content data will be described.

  First, in step S31, the control unit 61 (see FIG. 5) determines whether or not the reaction button (input numeric keypad 21a) has been pressed by the user of the mobile phone 101, and this determination until the reaction button is pressed. Is repeated. If it is determined in step S31 that the reaction button (input numeric keypad 21a) has been pressed, comment information (character image 1 and comment sentence 5) corresponding to the reaction button is transmitted to the mobile phone 102 in step S32. In step S33, comment information (character image 1 and comment sentence 5) corresponding to the reaction button is displayed on the display unit 10 (see FIG. 5) of the mobile phone 101.

  On the other hand, in step S41, the mobile phone 102 determines whether or not comment information (character image 1 and comment sentence 5) has been received from the mobile phone 101, and this determination is repeated until comment information is received. . If it is determined in step S41 that the comment information (character image 1 and comment sentence 5) has been received, the received comment information (character image 1 and comment sentence 5) is displayed on the display unit 10 of the mobile phone 102 in step S42. (See FIG. 5).

  At this time, in the first embodiment, individual comment information (character image 1 and comment sentence 5) transmitted by the user of the mobile phone 101 is stored in the flash ROM 66 together with the “master time” at that time.

  Thereafter, in step S34 in the mobile phone 101, it is determined whether or not about 2 seconds have elapsed since the comment information was displayed. If it is determined in step S34 that approximately 2 seconds have elapsed since the comment information was displayed, the comment information (character image 1 and comment sentence 5) displayed on the display unit 10 is not displayed in step S35. To. In addition, the same determination is made in step S43 of the mobile phone 102, and when it is determined that about 2 seconds have passed, the comment information (character image 1 and the comment image) displayed on the display unit 10 in step S44. Hide sentence 5).

  Thereafter, in step S36 in the mobile phone 101, it is determined whether or not the reproduction of the content data 70 has been completed. If it is determined in step S36 that the reproduction of the content data 70 has not been completed, the process returns to step S31, and the processes from step S31 to step S35 are repeated. If it is determined in step S36 that the reproduction of the content data 70 has been completed, the mobile phone 101 ends this control flow. In the above description, the control flow between the mobile phone 101 and the mobile phone 102 has been described. However, the same control as described above is performed between other mobile phones, so that the mobile phone in which the ad hoc network is formed. Communication between users between telephones is achieved.

  Next, with reference to FIGS. 5 and 12, a control operation related to a reproduction operation when the two mobile phones 101 and 102 simultaneously reproduce content data will be described.

  First, in step S51, the control unit 61 (see FIG. 5) determines whether or not the user of the mobile phone 101 has performed a button operation for rewinding the reproduction data (pressing operation of the selection operation button 20d). At the same time, this determination is repeated until a button operation for rewinding the reproduction data is performed. If it is determined in step S51 that the button operation for rewinding the reproduction data (the pressing operation of the selection operation button 20d) has been performed, the mobile phone 101 rewinds the mobile phone 102 in step S52. An “inquiry signal” for inquiring whether or not the operation (operation for simultaneous rewinding) is possible is transmitted.

  That is, in step S61, the mobile phone 102 determines whether or not an “inquiry signal” for inquiring whether or not the rewinding operation transmitted from the mobile phone 101 is received, and receives the “inquiry signal”. This judgment is repeated until. If it is determined in step S61 that the “inquiry signal” has been received, in step S62, a message indicating that the user of the mobile phone 101 wants to perform a rewind operation to the user of the mobile phone 102 (for example, “Rewind Is displayed on the display unit 10 (see FIG. 5).

  Then, in step S63, it is determined whether or not the “OK” button for permitting is selected by the pressing operation of the selection operation button 20d by the user of the mobile phone 102, and until the “OK” button is selected. This determination is repeated. If it is determined in step S63 that the “OK” button has been selected, a “permission signal” for permitting the rewinding operation by the user of the mobile phone 101 is transmitted to the mobile phone 102 in step S64.

  In steps S62 to S64 described above, after the user of the mobile phone 102 is inquired of whether or not the rewinding operation is possible, the user of the mobile phone 102 presses the “OK” button and returns a “permission signal”. However, when the mobile phone 102 receives an “inquiry signal”, it is preset on the mobile phone 102 side so as to return a “permission signal” for unwinding operation to the mobile phone 101 unconditionally. You may comprise so that. As a result, among the users who have received the “inquiry signal”, users who agree to be simultaneously rewound during simultaneous playback need not press the “OK” button each time the “inquiry signal” is received. Therefore, the user can concentrate on viewing the content data 70. Here, a change from the mode in which the “permission signal” of the rewinding operation is automatically returned to the mode in which the manual reply is performed (the mode in which the message is viewed and responded) is also possible during the viewing of the content data 70. Is possible.

  In step S53 in the mobile phone 101, it is determined whether or not the “permission signal” permitting the rewind operation transmitted from the mobile phone 102 is received, and this determination is performed until the “permission signal” is received. Repeated. If it is determined in step S53 that the “permission signal” has been received, in step S54, the content data 70 that is being reproduced in accordance with the rewinding operation (pressing the selection operation button 20d) by the user of the mobile phone 101 is displayed. Rewind. Thereafter, in step S55, the playback time of the content data 70 to be rewound (the playback time unique to the content data 70) and the “master time” at that time are transmitted to the mobile phone 102.

  Thereafter, in step S56, the reproduction of the content data 70 from the rewind position is started. Similarly, in step S65 in the mobile phone 102, the content data from the rewind position based on the reproduction time of the rewind destination content data 70 received from the mobile phone 101 and the “master time” at that time. 70 playback is started.

  In this way, the two mobile phones 101 and 102 simultaneously reproduce the content data 70 from the rewinded position at substantially the same timing in a state where an ad hoc network is formed. Although the control flow between the mobile phone 101 and the mobile phone 102 has been described above, the same control as described above is performed between other mobile phones.

  In the first embodiment, as described above, the control unit 61 is directed toward the mobile phones 102 to 104 based on the operation of the user of the mobile phone 101 who views the content data 70 while the content data 70 is being reproduced. Control of transmitting comment information (character image 1 and comment sentence 5) of the user of the mobile phone 101 with respect to the content data 70 being reproduced is performed by the wireless communication unit 64, and the mobile phone 102 to 104 is used to view the content data 70. The wireless communication unit 64 is configured to perform control to receive comment information (character image and comment text) of the user of the cellular phones 102 to 104 with respect to the content data 70 being reproduced transmitted from the users of the phones 102 to 104. By the mobile phone 101-104 When the same content data 70 is played back at the same time, the users (users of the mobile phone 101 and users of the mobile phones 102 to 104) who own each mobile phone are only allowed to view the content data 70 being played back. Instead, each person's comment information on the content data 70 being played back can be communicated to other users via their mobile phones (wireless communication unit 64). That is, the user of the mobile phone 101 can transmit his / her comment information to the users of the mobile phones 102 to 104, and the user of the mobile phone 102 to 104 transmits their comment information to the user of the mobile phone 101. I can tell you. Thereby, even in a situation where the same content data 70 is simultaneously viewed on different physically separated mobile phones, users who view the content data 70 reproduced at the same time can actively communicate with each other. .

  In the first embodiment, the control unit 61 causes the comment sentence 5 (5a to 5d) to be directed to the mobile phones 102 to 104 based on the operation of the user of the mobile phone 101 while the content data 70 is being reproduced.
