Description

  The present invention relates to a television receiver, in particular a television receiver capable of receiving multi-channel broadcasting such as digital broadcasting, an operation terminal device for performing an operation of the television receiver by communication, and these television receivers. The present invention relates to a channel list setting system using an operation terminal device and a channel list setting method.

  Currently, digital broadcasting in Japan is carried out on BS (Broadcasting Satellite), CS (Communication Satellite), and CATV (Cable TV). In digital broadcasting, digital signals can be transmitted several times more information than conventional analog broadcasting by using MPEG (Moving Picture Experts Group) compression coding technology. Therefore, the number of channels is so large that it cannot be compared with analog broadcasting, and the receiver can enjoy a wide variety of contents.

  Furthermore, from this year (2003), terrestrial digital broadcasting is to be started, and it is planned that analog broadcasting so far will be switched to digital broadcasting. At that time, the number of channels that can be viewed is expected to be 50 to 60 or more for general viewers.

In order to increase the number of channels, techniques for allowing viewers to select programs comfortably and easily have been proposed. For example, Patent Document 1 discloses a technique related to an interactive program guide system that provides an opportunity to access program-related information based on a user's judgment instead of simply displaying a large amount of program information.

  Another convenience problem associated with the increase in the number of channels is channel number setting. The setting of the channel list means that the user freely assigns a number to each receivable channel. When the number of channels is large, it becomes necessary for the user to select channels. For example, channels that are often viewed by the user are preferentially assigned a small number starting from 1. It is generally considered to manage this for your own convenience.

  By the way, conventionally, a television receiver (DTV) for receiving digital broadcasts and its remote controller have set channel lists independently. Therefore, the user has to set the channel list twice with the DTV and the remote controller.

  However, in that case, it takes a lot of time and effort to set up several tens or more channels. In addition, if the labor is forced twice in this way, even some setting changes become troublesome work.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Overview of DTV and palette display>
FIG. 1 shows an external configuration of a receiving system according to an embodiment of the present invention, and FIG. 2 is a functional configuration diagram thereof. The receiving system 300 includes at least a DTV 100 and a pallet display 200, and the DTV 100 and the pallet display 200 have a function of communicating with each other wirelessly.

  The DTV 100 is separated into a media receiver 10 that receives a video signal and a display 11 that receives the video signal from the media receiver 10 and displays an image. The display 11 is a large display such as a PDP (Plasma Display Panel) or LCD (Liquid Crystal Display). The media receiver 10 supplies the display 11 with various broadcast signals such as analog terrestrial waves and 110 ° CS digital broadcast and BS digital broadcast received using the BS / CS antenna 12. Channel selection at that time (channel selection) can be performed by any of external input from the channel selection button 13, input by the remote controller 30, and input by operation of the palette display 200. The 110 ° CS digital broadcast refers to a satellite broadcast that uses an artificial satellite “N-SAT-110” stationary in the direction of 110 ° east longitude, similarly to the BS digital broadcast BSAT-2a. Called CS (however, these are only examples, and other forms of receiving broadcast signals such as other CS broadcasts, terrestrial digital broadcasts, data broadcasts, audio-only broadcasts, etc. can also be implemented. Is).

  The pallet display 200 is placed on the cradle 201 and is carried and used by the user as necessary. The pallet display 200 performs various reception controls in conjunction with the DTV 100, and has a characteristic that the pallet display 200 itself has a display 22 while having a general control function like the remote controller 30. The display 22 is configured, for example, by laminating a touch panel on an LCD, and various user operations are performed by a GUI (Graphical User Interface) displayed on the touch panel.

  FIG. 3 shows an example of the initial screen of the display 22. On the screen, the display / sensor unit 22B functions as a touch panel, and an LCD image and a menu display 51 are displayed in other areas. As menu items, for example, a television channel list, a channel list, a television (TV) remote controller, and the like are set. For example, when the DTV 100 is configured to be able to receive data using the Internet, the channel list is used to access news or the like automatically distributed by the broadcast type Internet or a homepage additionally set by the user. Channels are added to the TV channel list. When the display / sensor unit 22B at the right end of the menu item is touched with the finger 60, the item is highlighted and processing related to the selection action is started. In addition, the selection can be canceled based on certain rules corresponding to the movement of the finger 60 and the like.

  FIG. 4 shows an example of a “TV channel list” display screen on the display 22. That is, channels that can be received by the DTV 100 are displayed as the channel display 52 on the display / sensor unit 22A of the touch panel. Specifically, categories of terrestrial, CS, BS, and input (video 1 to video 4) are set, and channels that can be received in each category are displayed as a channel selection button 52A that is a GUI. Here, when the user designates a channel by touching the channel selection button 52A, a channel selection control signal is transmitted from the palette display 200 to the DTV 100, and an image from the designated channel is displayed on the display 11. Yes.

  FIG. 5 shows an example of a display screen of “TV remote control” on the display 22. A remote control button 53 is displayed as a GUI as a remote control display 53 on the display / sensor unit 22A of the touch panel. Here, the channel switching buttons are 1 to 12 for terrestrial broadcasting, CS broadcasting, and BS broadcasting, respectively.

<Configuration of DTV and palette display>
Next, the principal part structure of DTV100 and the palette display 200 is demonstrated, referring FIG.

  In the DTV 100, the media receiver 10 processes video signals from channel selection and broadcast reception. The media receiver 10 receives a channel selection control unit 1 that controls each operation, a light receiving unit 2 that receives light from the remote controller 30, a communication control unit 3 that performs bidirectional communication with the palette display 200, CS, and BS digital signals. Digital tuner 4, analog tuner 5 for receiving terrestrial signals 5, video signal reproduction circuit 6, AV switch (SW) 7 for switching input signals, input signals from AVSW 7 are subjected to processing necessary for display and displayed 11 includes a signal processing circuit 8 to be sent to 11. The display 11 receives the image signal from the signal processing circuit 8 and displays it on the screen. Among these, detailed description of the same components as those of the conventional DTV is omitted.

  The channel selection control unit 1 has a function of receiving a channel selection control signal from an external input from the channel selection button 13 or an operation input from the remote controller 30 or the pallet display 200 and controlling input signal switching by the AVSW 7. At that time, the user selects a channel based on a channel number (hereinafter referred to as a display channel) set by the user for each channel. For this reason, the channel selection control unit 1 further includes a memory 1A, which stores a television broadcast channel list (channel lists 41, 42, 43).

  The channel list 41 is a channel list corresponding to terrestrial waves, and is a table in which absolute channels and display channels correspond as shown in FIG. The absolute channel is a number from 1 to 63 assigned to the legal frequency for channel identification. All actual broadcasts are received based on this absolute channel.

  The channel lists 42 and 45 are channel lists corresponding to BS broadcast and CS broadcast, respectively, and are tables in which absolute channels and broadcast station names correspond as shown in FIGS.

  The channel selection control unit 1 also has a function of creating / changing such a channel list. Here, the channel selection control unit 1 (i) receives a terrestrial wave from the analog tuner 5 in order to create / change the channel list 41, sets a display channel in accordance with each terrestrial broadcast, and (ii) ) BS and CS digital broadcast SI (Service Information) is received from the digital tuner 4, and a table is created in association with the display channel. By the way, SI includes NIT (Network Information Table), SDT (Service Description Table), etc., respectively, information related to program of all organized channels, information such as modulation frequency (corresponding to absolute channel), name of organized channel, Includes information such as broadcaster name. Of these methods defined in the MPEG2 system, a method called MPEG-TS (Transport Stream) is applied to the transmission of these data. In Japan, SI is defined as STD-B10 in the ARIB (Association of Radio Industries and Businesses) standard.

  Further, the channel selection control unit 1 (1) transmits the set or updated channel list to the palette display 200 via the communication control unit 3. On the contrary, (2) the channel list sent from the palette display 200 is received via the communication control unit 3, and the channel list is created / changed based on the received channel list.

  The palette display 200 includes a control unit 21 that performs various controls of the device, a display 22 that includes display / sensor units 22A and 22B, and a communication control unit 23 that performs bidirectional communication with the DTV 100. ing. For the wireless communication between the communication control unit 23 and the communication control unit 3 on the DTV 100 side, for example, the IEEE (Institute of Electrical and Electronics Engineers) 802.11 wireless method, more specifically, the 802.11a standard is applied. Good. As a result, a use band of 5.2 GHz and a maximum transmission speed of 54 Mbps can be realized.

  The palette display 200 holds a station name list 44 in advance and displays (1) the channel list 41 or (2) a channel list similar to the channel list 41 in order to display the above-mentioned “TV channel list” on the screen. 46 is set by itself.

  As shown in FIG. 9, the station name list 44 is an association of absolute channels and broadcast station names, and includes information on not only national broadcast stations but also regional broadcast stations. A memory 21A is attached to the control unit 21, and a station name list 44 and a necessary channel list are stored therein.

  Here, the control unit 21 (1) acquires the channel list created / changed by the DTV 100 via the communication control unit 23, or (2) creates / changes the channel list itself. ing. When creating / changing itself, the created channel list 46 is transmitted to the DTV 100. That is, in the present embodiment, the DTV 100 and the palette display 200 are configured such that when the channel list data is created / changed on one side, the channel list data is created / changed on the other side. Yes.

  Further, the control unit 21 combines the received channel list 41 or the channel list 46 created by itself with the station name list 44 to create a channel list 45 corresponding to the “TV channel list” of FIG. (See FIG. 10).

<Cooperation between DTV and palette display>
Next, main operations of the receiving system 300 will be described.

<DTV → pallet display>
First, (1) a case where the channel list 41 set in the DTV 100 is transmitted to the palette display 200 will be described.

(I) Terrestrial Channel List Setting FIG. 11 is a flowchart showing the operations of both the DTV 100 and the palette display 200 when setting the terrestrial channel list (channel list 41). First, the channel setting of the DTV 100 is performed as usual. That is, the user instructs the DTV 100 to select a channel by using, for example, the remote controller 30 and sets display channels one by one while checking the actual received video on the display 11 (step S1).

  At this time, in the DTV 100, when the channel selection control unit 1 receives the channel selection control signal from the remote controller 30 via the light receiving unit 2, the channel selection control unit 1 outputs a channel selection instruction to the analog tuner 5, and the modulation thereof. Attempt reception by changing frequency. Among the received broadcast signals, the image signal is input to the display 11 via the AVSW 7 and the signal processing circuit 8, and an image is displayed. Subsequently, the channel number set for the reception channel by the user, that is, the display channel is input from the remote controller 30 to the channel selection control unit 1. The channel selection control unit 1 creates a channel list 41 based on these (see FIG. 6) and stores it in the memory 1A. The item “BOX” in FIG. 6 corresponds to the operation button numbers 1 to 12 of the remote controller 30. Thus, a display channel different from the absolute channel can be set by the user's operation. In the example shown in the figure, the absolute channel 14 is assigned to the BOX No. 5, and the display channel is set to 25. In this case, when the fifth button of the remote controller 30 is pressed, the media receiver 10 selects the channel of the legal frequency corresponding to “14”, and “25” is displayed on the screen of the display 11 (channel setting). Later, all user operations will be performed based on the display channel). All operations after creation of the channel list 41 are automatically performed without any user operation.

  Next, the DTV 100 transfers the channel list 41 to the palette display 200 wirelessly (step S2). The media receiver 10 transmits the channel list 41 from the channel selection control unit 1 via the communication control unit 3.

  On the other hand, the palette display 200 receives the channel list 41 by the communication control unit 23 and inputs it to the control unit 21 (step S3). As a result, the pallet display 200 has acquired the channel setting content itself performed by the DTV 100, and the user does not need to perform channel setting again by relying on an external input.

  The palette display 200 further performs channel display 52 (see FIG. 4) on the display 22 based on the channel list 41. For this purpose, the control unit 21 reflects the contents of the station name list 44 (see FIG. 9) previously stored in the memory 21A in the channel list 41. That is, both are contrasted using the absolute channel as an index, and are combined into one list (channel list 45) as shown in FIG. 12 (step S4). The obtained channel list 45 is stored in the memory 21A. In this way, a channel list having the same contents as the DTV 100 is automatically set on the palette display 200 in conjunction with the setting of the channel list in the DTV 100.

  The channel list 45 is as shown in FIG. In the figure, the channel item indicated by “-” is 0 (0xFF) on the protocol. Therefore, if there is a BOX whose absolute channel is “-” in the channel list 45 (step S5; N), the channel is regarded as unreceivable and the button display by the GUI is not performed (step S5). S7). In the example of the figure, BOX11 corresponds to this.

  If there is no broadcast station name (step S6; N), the channel is not included in the area information of the station name list 44, so it is assumed that the channel cannot be received and a button is displayed using the GUI. (Step S7). In the example of FIG. 10, BOX2 corresponds to this. In this case, since the absolute channel “24” does not exist in the station name list 44, it is not displayed.

  Therefore, when there is an absolute channel (step S5; Y) and there is a broadcast station name (step S6; Y), a channel selection button 52A indicating the display channel of the BOX and the broadcast station name is displayed on the screen of the display 22. To display. The order of the channel selection buttons 52A at this time is, for example, the display channel number order. Thereby, the channel display 52 can be displayed (step S8).

  In this manner, in the DTV 100 and the palette display 200, channel setting for terrestrial waves is performed by a single setting input.

(Ii) Channel List Setting for Digital Broadcasting FIG. 13 is a flowchart showing the operations of both the DTV 100 and the palette display 200 when setting the channel lists (channel lists 42 and 43) for digital broadcasting. First, channel setting in the DTV 100 is performed. That is, the channel selection control unit 1 receives data necessary for creating the channel lists 42 and 43 via the digital tuner 4. Specifically, NIT and SDT are separated from the received broadcast signal using a Demux (demultiplexer; separation circuit) provided in the digital tuner 4 and input to the channel selection control unit 1. From the NIT, the channel of the receivable broadcasting station is acquired, and the name of the broadcasting station is acquired from the SDT. Based on these pieces of information, channel lists 42 and 43 are created (see FIGS. 7 and 8 / step S11).

  Next, the channel selection control unit 1 stores the channel lists 42 and 43 in the memory 1A and transfers them to the pallet display 200 by wireless communication via the communication control unit 3 (step S12).

  On the other hand, the palette display 200 receives the channel lists 42 and 43 at the communication control unit 23 and inputs them to the control unit 21 (step S13). Thereby, in the pallet display 200, the setting contents of the channel set in the DTV 100 are acquired, and it is not necessary to perform the channel setting again. The channel lists 42 and 43 are stored in the memory 21A. Thus, in the palette display 200, a channel list having the same contents as the channel list of the DTV 100 is set in conjunction with the setting of the channel list in the DTV 100.

  The palette display 200 further performs channel display 52 (see FIG. 4) on the display 22 based on the channel lists 42 and 43. That is, a channel selection button 52A in which an absolute channel and a corresponding broadcasting station name are written is displayed on the screen of the display 22. The order of the channel selection buttons 52A at this time is, for example, the display channel number order. Thereby, the channel display 52 can be displayed (step S14).

  In this way, in the DTV 100 and the palette display 200, channel setting for CS / BS digital broadcasting is performed by a single setting input.

[Modification]
In the above, an example in which the received absolute channel and broadcast station name are used as they are as a channel list for digital broadcasting has been described. However, the user can set display channels even when creating a channel list for digital broadcasting. is there. For example, as in the case of creating a list of terrestrial waves, a channel selection instruction is performed using the remote controller 30 and display channels are set one by one while checking actual received video on the display 11. In this case, the channel selection control unit 1 may create a channel list in which the display channel is added to the broadcast station name and the absolute channel, and the channel list may be transferred to the palette display 200.

<Palette display → DTV>
Next, (2) a case where the channel list 46 set on the palette display 200 is transmitted to the DTV 100 will be described.

  FIG. 14 is a flowchart showing the operations of both the DTV 100 and the palette display 200 when setting the channel list on the palette display 200. First, a channel list is created on the pallet display 200. Since the pallet display 200 itself does not include a tuner, display channels are set by communicating wirelessly with the tuners 4 and 5 of the DTV 100.

  Specifically, first, a tuning instruction is sent from the control unit 21 on the pallet display 200 side to the tuning control unit 1 on the DTV 100 side via the communication control unit 23 and the communication control unit 3 (step S21).

  The channel selection control unit 1 controls the tuners 4 and 5 and the AVSW 7 in accordance with the channel selection instruction sent thereto so as to receive and display a predetermined absolute channel. Furthermore, the channel selection control unit 1 confirms whether or not actual reception is possible at this time (step S22). Information on the success or failure of reception is data d, and is sent from the tuning control unit 1 to the control unit 21 in response to the tuning instruction (step S23).

  When the control unit 21 receives the data d and confirms the absolute channel that can be actually received in this area from the information, the control unit 21 compares the channel name list 44 stored in the memory 21A in advance with the channel list. 46 is created (step S24). Therefore, the channel list 46 includes information on (absolute channel, broadcast station name). Note that it is desirable to set the display channel so as to correspond to the absolute channel at this time or during the previous channel selection. This is because the palette display 200 is configured to display to the user using the display channel as described above. In this case, the channel list 46 includes (absolute channel, display channel, broadcast station name).

  The control unit 21 stores the channel list 46 in the memory 21A and displays the channel list 46 as the channel selection button 52A on the screen of the display 22 (step S25). Meanwhile, the control unit 21 transfers the channel list 46 to the DTV 100 by wireless communication via the communication control unit 23 (step S26). The content to be transferred may be only (absolute channel, display channel) or (absolute channel, broadcast station name), or (absolute channel, display channel, broadcast station name). That is, the DTV 100 may transmit data including necessary information among information in the channel list acquired by the palette display 200. Here, (absolute channel, display channel) is transmitted, but the transmission content is determined according to the function of the DTV 100.

  In the DTV 100, the channel list 46 is received by the communication control unit 3 and input to the channel selection control unit 1. As a result, in the DTV 100, the setting contents of the channel set on the palette display 200 are acquired, and it is not necessary to perform the channel setting again. These channel lists 46 are stored in the memory 1A. Thus, in the DTV 100 as well, a channel list having the same content as the channel list on the palette display 200 is set in conjunction with the channel list setting on the palette display 200 (step S27).

  In the above description of the operation, the remote controller 30 is used for channel selection at the time of channel setting and display channel setting operation. However, not only the remote control 30 but also the channel selection button 13 is used as a means for performing such operation. Furthermore, the operation screen of the pallet display 200 can be used.

  In the above description, the operation when creating the channel list has been described. However, the basic operation is the same even when updating, except that the contents of the memory are rewritten (overwritten). In the case of partial rewriting, the transmission data may be the entire channel list table, or only the data related to the change. Rewriting in the memories 1A and 21A may be performed only for the part related to the change, or a control method may be adopted in which the whole is overwritten at the time of update.

  As described above, according to the present embodiment, (1) when the DTV 100 creates / changes a channel list, the channel list is transmitted to the palette display 200 and is also created / changed on the palette display 200. (2) When creating / changing the channel list on the palette display 200, the channel list is transmitted to the DTV 100 and created / changed on the DTV 100, so the contents of both channel lists match. It will be a thing. Therefore, in either case, both channel list settings are executed by a single setting input, and the double labor for creating and changing separately can be halved. Therefore, the receiving system 300 can easily set and change channels, and the user can be provided with a usage environment in which channel management can be performed relatively freely.
