Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First Embodiment)
FIG. 1 is a block diagram showing a broadcast receiving device according to the first embodiment.

In FIG. 1, the antenna 21 receives an advanced BS broadcast and an advanced wide band CS broadcast (hereinafter, these are referred to as an advanced wideband broadcast) and supplies an advanced wideband broadcast signal to the input terminal 2a of the broadcast receiving device 1. The advanced wideband broadcast signal input to the input terminal 2a is supplied to the tuner unit Tu.

The broadcast receiving device 1 includes a control unit 10. The control unit 10 may be configured by a processor using a CPU or the like and operate according to a program stored in the ROM 10a to control each unit, or a part or all of the functions in a hardware electronic circuit. It may be the one that realizes.

The tuner unit Tu has a plurality of tuners Tu1, Tu2, ... (Hereinafter, these are collectively referred to as tuner Tun). The tuner Tun is controlled by the control unit 10 to select a broadcast signal of a desired channel from the input high-bandwidth broadcast signals, and outputs the selected signal to the signal processing unit 3. The signal processing unit 3 demodulates the input broadcast signal.

In the example of FIG. 1, only the antenna 21 corresponding to one advanced wideband broadcasting is shown, but an antenna corresponding to terrestrial digital broadcasting, BS broadcasting, and wide band CS broadcasting is provided, and the signal from each antenna is sent to the tuner unit Tu. It may be supplied. In this case, the signal processing unit 3 performs demodulation corresponding to the modulation method of each broadcast. As a result, the signal processing unit 3 can obtain a stream of each broadcast signal. Although FIG. 1 shows an example in which each broadcast signal is input via an antenna, the transmission path of the broadcast signal is not particularly limited, and an IP broadcast received via an Internet line without going through an antenna. Or, it may be received via a cable television broadcasting network.

For example, for an advanced wideband broadcast signal, a TLV (Type Length Value) stream can be obtained by demodulation of the signal processing unit 3. The signal processing unit 3 separates the IP packet contained in the TLV stream, and includes video data, audio data, subtitle data, character super, application data, ECM (Entitlement Control Message), and EMM (Entitlement Management Message) contained in the IP packet. ), And remote control key descriptors are extracted. The remote control key descriptor will be described later.

The signal processing unit 3 extracts a transport stream (a transport stream multiplexed according to the MPEG-2 Systems standard) by demodulation processing for the terrestrial digital broadcast signal. Further, the signal processing unit 3 extracts video data and audio data from the transport stream, and also extracts various messages including ECM and EMM.

Further, the signal processing unit 3 performs decoding processing on the video data and audio data of each broadcasting system and then performs predetermined signal processing to obtain video data and audio data. The signal processing unit 3 gives video data and audio data to the graphic processing unit 4 or the audio processing unit 7, respectively, and gives other data to the control unit 10. The OSD signal generation unit 5 generates image information (OSD signal) for superimposing display based on the information given by the control unit 10 and supplies it to the graphic processing unit 4.

The graphic processing unit 4 superimposes the digital video data from the signal processing unit 3 and the image based on the GUI (Graphical User Interface) from the OSD signal generation unit 5, and sends the superposed image to the video processing unit 6. ..

For example, in addition to video data, various data for acquiring a program, electronic program guide (EPG) information, program attribute information, subtitle information, etc. are given to the graphic processing unit 4, and the graphic processing unit 4 inputs these. Image generation processing for displaying EPG, subtitles, etc. can be performed based on the obtained information.

The video processing unit 6 is controlled by the control unit 10 to convert the digital broadcast signal from the graphic processing unit 4 into a format (number of pixels, frame frequency, scanning method) that can be displayed by the video display unit 8, and display colors. Is arbitrarily adjusted and output to the video display unit 8. As a result, the image can be displayed on the display screen of the image display unit 8.

Further, the voice processing unit 7 converts the digital voice data from the signal processing unit 3 into an analog signal that can be reproduced by the speaker 9, and then outputs the digital voice data to the speaker 9 to reproduce the voice. If the broadcast receiving device is a set-top box or the like, it is not necessary to include the video display unit 8 and the speaker 9.

The broadcast receiving device 1 is provided with a card interface (I / F) 13, communication I / F16, USBI / F17, and HDMII / F18. The card I / F 13 enables data to be transmitted / received between the IC card 23 mounted on the card holder 14 and the control unit 10. For example, when a CAS card compatible with the current digital broadcasting is adopted as the IC card 23, the card I / F 13 transmits / receives data related to the descramble of the current broadcasting.

The communication I / F 16 is an interface corresponding to a predetermined communication path such as IEEE 1394, and is connected to an external device (not shown) via a terminal 2b to enable data transmission / reception between the external device and the control unit 10. .. The HDMI / F18 is an interface compatible with the HDMI (registered trademark) standard, and is connected to an external device (not shown) via the terminal 2d to receive an HDMI signal from the external device and output it to the control unit 10. , The HDMI signal from the control unit 10 can be output to an external device via the terminal 2d.

The USB I / F17 is an interface compatible with the USB standard, and is connected to a USB compatible device such as an HDD 24 via a terminal 2c to enable data transmission / reception between the USB compatible device and the control unit 10. For example, when the HDD 24 is connected to the terminal 2c, the control unit 10 can give video data to the HDD 24 via the USB I / F17 and the terminal 2c for recording. The control unit 10 can also record a signal of a broadcast program by configuring the recording unit with a built-in HDD, an optical disk drive, an SD (registered trademark) card reader / writer, or the like.

The broadcast receiving device 1 is provided with an operation unit 11 and a receiving unit 12. The operation unit 11 is composed of switches, keys, buttons and the like (not shown), and outputs an operation signal based on the user operation to the control unit 10. Further, the receiving unit 12 receives an operation signal based on the user operation from the remote controller (hereinafter referred to as a remote controller) 22 and outputs the received operation signal to the control unit 10. The control unit 10 controls each unit of the broadcast receiving device 1 based on the operation signals from the operation unit 11 and the reception unit 12. For example, when the remote controller 22 performs an operation of designating a reception channel number with an up / down key, a one-touch channel selection button, or the like, each tuner tune performs a channel selection operation according to an operation signal from the remote controller 22. Do.

The broadcast receiving device 1 is provided with a CAS module 15. The CAS module 15 is used for controlling the limited reception system. The master key Km unique to the module is stored in the CAS module 15. The EMM extracted by the signal processing unit 3 includes a work key Kw for descramble. This EMM is encrypted with an individual master key Km for each module, and the CAS module 15 decrypts the EMM given by the control unit 10 using the master key Km to acquire the work key Kw.

Broadcast data may be encrypted with the scramble key Ks. The scrambled keys Ks are multiplexed and transmitted to the ECM. This ECM is encrypted by a work key Kw that is variable for each broadcaster, and the CAS module 15 uses the stored work key Kw to decrypt the ECM given by the control unit 10 and scramble the key. Get Ks. The scramble key Ks from the CAS module 15 is supplied to the signal processing unit 3 via the control unit 10, and the signal processing unit 3 performs descramble processing using the scramble key Ks.

The scrambled key Ks is updated in a relatively short time, and the CAS module 15 always acquires the scrambled key Ks and outputs the scrambled key Ks to the signal processing unit 3 while viewing the scrambled program. When a CAS card is used as the IC card 23, the decoding operation of the CAS card is the same as that of the CAS module 15.

Here, the remote control key descriptor will be described. The remote control key descriptor is one of the standards for advanced BS broadcasting, and is included in the broadcasting signal of advanced BS broadcasting in particular among the advanced wideband broadcasting signals. The broadcast station is automatically assigned to the one-touch channel selection button of the remote controller 22 by the remote control key descriptor included in the broadcast signal.

As described above, the remote control key descriptor is extracted from the advanced wideband broadcast signal by the signal processing unit 3. The signal processing unit 3 outputs the extracted remote control key descriptor to the control unit 10. That is, the signal processing unit 3 constitutes an extraction unit that receives the broadcast signal and extracts setting information (remote control key descriptor) for automatically setting the one-touch channel selection button of the remote controller 22 from the broadcast signal.

The control unit 10 generates remote control setting information in which a broadcasting station (broadcasting company) is automatically assigned to the one-touch channel selection button of the remote control 22 based on the remote control key descriptor from the signal processing unit 3. The control unit 10 stores the remote control key descriptor from the signal processing unit 3 and the generated remote control setting information in the non-volatile memory 10c. When the user performs an operation of designating a reception channel number with a one-touch channel selection button or the like, an operation signal is input from the remote controller 22 to the control unit 10 via the reception unit 12. When the operation signal is input, the control unit 10 refers to the remote control setting information stored in the non-volatile memory 10c and performs a channel selection operation according to the operation signal.

Further, in the present embodiment, the setting of the one-touch tuning button can be set manually.

FIG. 2 is a diagram showing an example of a screen for setting a one-touch tuning button. When the user presses the "setting" key of the remote controller 22 and selects the setting of the one-touch tuning button, the one-touch tuning button setting screen 31 shown in FIG. 2 is displayed on the video display unit 8. The one-touch tuning button setting screen 31 is generated by the OSD signal generation unit 5 under the control of the control unit 10.

The user can set any broadcasting station to any one-touch channel selection button by operating a predetermined button on the remote controller 22. With this function, the user can customize which broadcasting station is assigned to the one-touch channel selection button. Further, when the user presses the [blue] button of the remote controller 22, the broadcasting station can be automatically assigned to the one-touch channel selection button based on the information of the remote control key descriptor stored in the non-volatile memory 10c. ..

When the user presses the [blue] button of the remote controller 22, the signal processing unit 3 inputs the remote control key descriptor (setting information for automatically setting the one-touch tuning button of the remote controller 22) extracted from the broadcast signal. It may be used to automatically assign a broadcasting station to the one-touch channel selection button.

Further, the remote control key descriptor is periodically included in the broadcast signal of the advanced BS broadcast at predetermined intervals even when there is no update information of the one-touch tuning button. Therefore, the remote control key descriptor is input to the control unit 10 from the signal processing unit 3 at predetermined intervals. The control unit 10 compares the input remote control key descriptor with the remote control key descriptor stored in the non-volatile memory 10c. The control unit 10 does not update the remote control setting information when the comparison results are the same, that is, when there is no update information for the one-touch tuning button. On the other hand, the control unit 10 updates the remote control setting information when the comparison results are different, that is, when there is update information of the one-touch tuning button.

However, when the user customizes the broadcasting station assigned to the one-touch channel selection button of the remote controller 22, updating the remote controller setting information is inconvenient for the user.

Therefore, the broadcast receiving device 1 of the present embodiment is configured so that the user can select whether or not to automatically set the one-touch tuning button.

FIG. 3 is a diagram showing an example of a selection screen for selecting the automatic setting of the one-touch tuning button. When the user presses the "setting" key of the remote controller 22 and selects the automatic setting of the one-touch tuning button, the selection screen 32 for selecting the automatic setting of the one-touch tuning button shown in FIG. 3 is displayed on the video display unit 8. Will be done. The selection screen 32 is generated by the OSD signal generation unit 5 under the control of the control unit 10.

When the selection screen 32 is displayed on the video display unit 8, the user selects "update" or "do not update" with the up / down keys of the remote controller 22, and presses the enter key of the remote controller 22. As a result, the user can set whether or not to automatically set the one-touch tuning button.

The control unit 10 "updates" the input remote control key descriptor and the remote control key descriptor stored in the non-volatile memory 10c when the comparison result is different and the one-touch channel selection button is automatically set. When is selected, the remote control setting information in which the broadcasting station is automatically assigned to the one-touch channel selection button of the remote control 22 is generated based on the updated remote control key descriptor.

When "update" is selected in the automatic setting of the one-touch tuning button, the control unit 10 updates the one-touch tuning button and one-touch tuning when there is update information of the one-touch tuning button. Notify the user that the button has been updated. For example, the control unit 10 issues a notification from the machine so that the user can see the notification from a predetermined menu, or controls the OSD signal generation unit 5 to display a pop-up message on the video display unit 8.

Further, when the one-touch tuning button is automatically updated, the control unit 10 displays, for example, the newly assigned one-touch tuning button so that the user can recognize it.

FIG. 4 is a diagram showing an example of a screen of a program guide displayed by a newly assigned one-touch channel selection button.

For example, when a broadcasting station of "HHH" is newly assigned to the "8" number of the one-touch tuning button, the control unit 10 controls the OSD signal generation unit 5 and newly assigns it, as shown in FIG. The logo 42 as an identifier indicating a new addition is displayed on the one-touch tuning button. The logo 42 may be displayed once and then not displayed again, or may be displayed for a predetermined period, for example, several days.

In the present embodiment, the logo 42 is used as the identifier, but the identifier is not limited to the logo 42, and it can be identified that a new addition has been made, such as changing the color of the icon or characters. Anything can be used.

On the other hand, the control unit 10 has a different comparison result between the input remote control key descriptor and the remote control key descriptor stored in the non-volatile memory 10c, and is "updated" by the automatic setting of the one-touch channel selection button. When "No" is selected, the one-touch channel selection button is not updated.

When "Do not update" is selected in the automatic setting of the one-touch tuning button and there is update information of the one-touch tuning button (from the current allocation of the one-touch tuning button, at least one control unit 10 is used. When receiving a remote control key descriptor whose assignment changes for the one-touch tuning button), the user is notified that there is update information for the one-touch tuning button. For example, the control unit 10 issues a notification from the machine so that the user can see the notification from a predetermined menu, or controls the OSD signal generation unit 5 to display a pop-up message on the video display unit 8. For example, when the control unit 10 receives a remote control key descriptor that changes to a number that is not currently assigned for a broadcasting station that cannot be received, the allocation of the current one-touch channel selection button does not change as a receiving device. Therefore, in such a case, the user is not notified that there is update information of the one-touch tuning button.

Next, the update process of the one-touch tuning button of the present embodiment will be described with reference to FIG.

FIG. 5 is a flowchart showing an example of the update process of the one-touch tuning button according to the first embodiment.

First, the signal processing unit 3 extracts the remote control key descriptor from the broadcast signal (S1). Next, the control unit 10 compares the remote control key descriptor extracted by the signal processing unit 3 with the previous remote control key descriptor stored in the non-volatile memory 10c (S2).

The control unit 10 determines whether or not the comparison results match (S3). When the control unit 10 determines that the comparison results match (S3: YES), that is, when the remote control key descriptor has not been updated, the control unit 10 returns to the process of S1 and repeats the same process.

On the other hand, when the control unit 10 determines that the comparison results do not match (S3: NO), that is, when the remote control key descriptor is updated, whether or not the automatic update of the one-touch tuning button is set. (S4).

When the control unit 10 determines that the automatic update of the one-touch tuning button is set (S4: YES), the control unit 10 updates the one-touch tuning button based on the updated remote control key descriptor (S5). End the process.

On the other hand, when the control unit 10 determines that the automatic update of the one-touch tuning button is not set (S4: NO), the control unit 10 ends the process without updating the one-touch tuning button (S6).

As described above, the broadcast receiving device 1 of the present embodiment allows the user to select whether or not to automatically set the one-touch tuning button on the selection screen 32 for selecting the automatic setting of the one-touch tuning button. .. A user who customizes the assignment of the one-touch tuning button and does not want to automatically set the one-touch tuning button sets the automatic setting of the one-touch tuning button to "do not update" in advance on the selection screen 32. As a result, the user who does not want to automatically set the one-touch tuning button does not change the assignment of the one-touch tuning button even if the remote control key descriptor is updated.

On the other hand, a user who wants to constantly update the assignment of the one-touch tuning button to the latest information sets the automatic setting of the one-touch tuning button to "update" in advance on the selection screen 32. As a result, the user who wants to always update the one-touch tuning button assignment to the latest information will always have the one-touch tuning button assignment updated to the latest information when the remote control key descriptor is updated.

Therefore, according to the broadcast receiving device 1 of the present embodiment, it is possible to set whether or not to automatically update the one-touch tuning button.

The control unit 10 of the second embodiment compares the remote control key descriptor input from the signal processing unit 3 with the remote control key descriptor stored in the non-volatile memory 10c. Then, when the comparison results are different, the control unit 10 displays a selection screen 51 on the video display unit 8 for selecting whether or not to update the one-touch tuning button shown in FIG. The selection screen 51 is generated by the OSD signal generation unit 5 under the control of the control unit 10.

When the selection screen 51 is displayed on the video display unit 8, the user selects "update" or "do not update" with the up / down keys of the remote controller 22, and presses the enter key of the remote controller 22. As a result, the user can select whether or not to update the one-touch tuning button.

In this way, the OSD signal generation unit 5 as the screen generation unit generates the selection screen 51 for selecting whether or not to update the one-touch tuning button of the remote controller 22 when the remote control key descriptor is updated. To do.

That is, in the first embodiment, when the remote control key descriptor is updated, the user sets in advance whether or not to update the one-touch tuning button by using the selection screen 32.

On the other hand, in the present embodiment, when the remote control key descriptor is updated, the selection screen 51 is displayed on the video display unit 8, and the user asks whether or not to update the one-touch tuning button each time. It is configured to be selected (set).

Even if the remote control key descriptor is updated, for example, if a remote control key descriptor that changes to a number that is not currently assigned is received for a broadcasting station that cannot be received, the receiving device can be used as a receiving device. Since the allocation of the current one-touch tuning button does not change at all, in such a case, the user may not be notified that there is update information of the one-touch tuning button. By doing so, it is possible to omit unnecessary operations for notification by the user.

Further, in the present embodiment, when the remote control key descriptor is updated, the selection screen 51 is displayed on the video display unit 8, and the user selects (sets) whether or not to update the one-touch tuning button each time. ), It is possible to omit the process of having the user set in advance whether or not to update the one-touch tuning button by using the selection screen 32 of FIG.

Next, the update process of the one-touch tuning button of the present embodiment will be described with reference to FIG. 7.

FIG. 7 is a flowchart showing an example of the update process of the one-touch tuning button according to the second embodiment. In FIG. 7, the same processing as in FIG. 5 is designated by the same reference numerals and the description thereof will be omitted.

When the control unit 10 determines in the processing of S3 that the comparison results do not match (S3: NO), the control unit 10 controls the OSD signal generation unit 5 to select whether or not to update the one-touch tuning button. The selection screen 51 is displayed on the video display unit 8 (S11).

Next, the control unit 10 determines whether or not to update the one-touch tuning button (S12). When the user selects "update" on the selection screen 51, the control unit 10 determines that the one-touch tuning button is updated (S12: YES), and one-touch based on the updated remote control key descriptor. The channel selection button is updated (S5), and the process ends.

On the other hand, when the user selects "do not update" on the selection screen 51, the control unit 10 determines that the one-touch tuning button is not updated (S12: NO), and does not update the one-touch tuning button (S12: NO). S6), the process is terminated.

By the above processing, the broadcast receiving device 1 can select whether or not to update the one-touch tuning button when the remote control key descriptor is updated, and updates the one-touch tuning button.
