Description

  The present invention relates to a television broadcast receiver, and in particular, can receive both terrestrial analog broadcasts and terrestrial digital broadcasts, and can effectively cope with a planned terrestrial analog broadcast stoppage. The present invention relates to a television broadcast receiver.

  Currently, in terrestrial television broadcasting, terrestrial analog broadcasting and terrestrial digital broadcasting are mixed (simultaneous broadcasting), but in 2011, terrestrial analog broadcasting was canceled and terrestrial digital broadcasting was stopped. Broadcasting only will be implemented. In such a broadcast form, in a television broadcast receiver that can receive both terrestrial analog broadcast and terrestrial digital broadcast, the user receives terrestrial analog broadcast and terrestrial digital broadcast. The operation for selecting the menu screen and the remote control operation by the user are complicated, and a very complicated operation is required. Moreover, the television broadcast receiver is provided with an operation program corresponding to reception of terrestrial analog broadcast and reception of terrestrial digital broadcast, and the burden is increased even during processing of this operation program.

  This type of television broadcast receiver has, as its reception performance, terrestrial analog broadcast and terrestrial digital broadcast interfere with each other when receiving terrestrial analog broadcast or terrestrial digital broadcast, for example, It is known to cause interference with the same channel, adjacent channel, and the like. For this reason, in such a television broadcast receiver, in order to reduce the influence of these disturbing broadcasts, in addition to adjusting the reception level of the necessary broadcast signal, an operation program is provided so as to obtain an optimum broadcast reception state. Used to perform necessary processing.

  By the way, in a television broadcast receiver that can receive terrestrial analog broadcasting and terrestrial digital broadcasting, when only terrestrial digital broadcasting can be received, power supply voltage is selectively supplied to the digital processing circuit. In order to reduce power consumption at the receiver, and when terrestrial analog broadcasting and terrestrial digital broadcasting are present in an adjacent state, the presence or absence of each broadcast is surely confirmed, and the broadcast is selected. On the other hand, a television broadcast receiver having means for operating only a necessary processing circuit is known, and an example is WO99-093056.

When receiving a terrestrial analog broadcast, such a television broadcast receiver processes the received signal to extract an audio signal, and processes the received signal when receiving a terrestrial digital broadcast. Digital processing circuit for extracting audio signal, switching circuit for selectively extracting audio signal from analog processing circuit or audio signal from digital processing circuit, control circuit for controlling power supply voltage of digital processing circuit, terrestrial digital broadcasting And a control circuit for supplying a power supply voltage to the digital processing circuit only when the detection circuit detects a terrestrial digital broadcast channel selection at the time of channel selection. It is intended to reduce power consumption.
WO99-093056

  Television broadcast receivers that can receive both terrestrial digital broadcasts and terrestrial analog broadcasts are complicated by the user's menu screen selection operations and user remote control operations, as described above. When operating, it can be very stressful, and even when processing an operation program corresponding to reception of terrestrial analog broadcasting and reception of terrestrial digital broadcasting, the processing is terrestrial analog broadcasting and terrestrial digital broadcasting. Therefore, it is complicated, and the processing load is very large, for example, internal processing is performed even for broadcasts that are not viewed.

  Moreover, in the current terrestrial television broadcasting, terrestrial analog broadcasting and terrestrial digital broadcasting are mixed, and in many reception areas, those multiple channels are in the same frequency band (for example, UHF band, etc.). ) Are broadcast in each. In such a case, the terrestrial analog broadcast wave and the terrestrial digital broadcast wave respectively interfere with other broadcasts, for example, the same channel interference, adjacent channel interference, and the like. For this reason, when receiving a terrestrial digital broadcast, this type of television broadcast receiver adjusts the reception level at the tuner input unit when receiving a channel selection channel.

  This reception level adjustment is performed when the reception status of the received digital terrestrial broadcasting is judged to be inferior due to the interference of the adjacent channel or the same channel, based on the bit error rate, etc. This is related to means for reducing the influence of disturbing broadcast waves. However, since this means reduces the amplification of the received signal, the performance of the original digital terrestrial broadcasting is reduced, and the resistance to other interference factors deteriorates, resulting in a decrease in performance. Therefore, there may be a case where it is impossible to receive a good broadcast.

  In addition, the television broadcast receiver according to the above-mentioned WO99-093056 supplies the power supply voltage to the digital processing circuit only when the channel selection of the terrestrial digital broadcast is detected, thereby the consumption of the television broadcast receiver. Although it is possible to reduce power consumption, it eliminates the complexity of the processing of the operation program used in the TV broadcast receiver and reduces the complexity of the operation by the user used in the TV broadcast receiver. It is not something to be solved.

  The present invention has been made in view of such a technical background.

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

  FIG. 1 is a block diagram showing the main configuration of a television broadcast receiver according to this embodiment, which can receive both terrestrial digital broadcast and terrestrial analog broadcast.

  As shown in FIG. 1, the television broadcast receiver 10 includes a digital tuner 1 including a channel selection unit 1a that receives a terrestrial digital broadcast, an analog tuner 2 including a channel selection unit 2a that receives a terrestrial analog broadcast, MPEG processing unit 3, analog processing unit 4, video / audio output unit 5, video display unit 6, audio output unit 7, control unit 8, operation unit 9, digital broadcast input terminal ID, analog And a broadcast input terminal IA. In addition, a broadcast receiving antenna 11 and a distributor 12 are arranged outside the television broadcast receiver 10. In FIG. 1, in order to simplify the description, the BS digital broadcast receiving unit, the B-CAS card unit, the encryption descrambling processing unit, etc., which are not directly related to the television broadcast receiver 10 of the present invention, Notation is omitted.

  The digital tuner 1 has an input terminal connected to the digital broadcast input terminal ID and an output terminal connected to the input terminal of the MPEG processing unit 3. The analog tuner 2 has an input end connected to the analog broadcast input terminal IA and an output end connected to the input end of the analog processing unit 4. The MPEG processing unit 3 has an output terminal connected to the first input terminal of the video / audio output unit 5, and the analog processing unit 4 has an output terminal connected to the second input terminal of the video / audio output unit 5. The video / audio output unit 5 has a video output end connected to the input end of the video display unit 6 and an audio output end connected to the input end of the audio output unit 7. The control unit 8 includes control units 1 a of the digital tuner 1, a channel selection unit 2 a of the analog tuner 2, an MPEG processing unit 3, a video / audio output unit 5, a video display unit 6, an audio output unit 7, and an operation unit 9. Connected to each. The distributor 12 has an input terminal connected to the terrestrial broadcast receiving antenna 11, a digital broadcast output terminal connected to the digital broadcast input terminal ID, and an analog broadcast output terminal connected to the analog broadcast input terminal IA.

  In this case, when an operator such as a user operates the operation unit 9 to select a desired digital broadcast channel, the control unit 8 is supplied with channel selection information capable of selecting the broadcast channel to the channel selection unit 1a. The tuner 1 selects the broadcast channel. Similarly, when an operator such as a user operates the operation unit 9 to select a desired analog broadcast channel, channel selection information capable of selecting the broadcast channel is supplied to the channel selection unit 2a, and the analog tuner 2 Select a broadcast channel. The MPEG processing unit 3 separates the service (video / audio / data, etc.) selected by the user from the transport stream defined by the MPEG standard, and the video / audio signal for each separated service (elementary stream). The MPEG decoding process is performed. The video / audio output unit 5 supplies the video signal formatted to the connected video display unit 6 to the video display unit 6 and supplies the audio signal to the audio output unit 7. The distributor 12 distributes the broadcast signal received by the terrestrial broadcast receiving antenna 11 into the terrestrial digital broadcast signal and the terrestrial analog broadcast signal, and supplies the terrestrial digital broadcast signal to the digital broadcast input terminal ID. The terrestrial analog broadcast signal is supplied to the analog broadcast input terminal IA.

  Here, the operation of the television broadcast receiver shown in FIG. 1 will be described.

  Now, when a digital broadcast signal is supplied to the digital broadcast input terminal ID and the digital broadcast signal is input to the digital tuner 1, the digital tuner 1 is selected by the channel selection unit 1a from the digital broadcast signal. The digital broadcast signal of the selected channel is extracted, the digital broadcast signal is subjected to processing such as digital demodulation, transmission descrambling, deinterleaving and error correction, and the obtained demodulated signal is supplied to the MPEG processing unit 3 . As described above, the MPEG processing unit 3 decodes the demodulated signal by MPEG to form a video / audio signal, supplies the video signal to the video display unit 6 for video display, and converts the audio signal to the audio output unit. 7 for audio output.

  On the other hand, when an analog broadcast signal is supplied to the analog broadcast input terminal IA and the analog broadcast signal is input to the analog tuner 2, the analog tuner 2 is selected by the channel selection unit 2a from the digital broadcast signal. The analog broadcast signal of the selected channel is extracted, the analog broadcast signal is subjected to processing such as analog demodulation, and the obtained demodulated signal is supplied to the analog processing unit 4. The analog processing unit 4 forms a video / audio signal from the obtained demodulated signal, supplies the video signal to the video display unit 6 to display the video, and outputs the audio signal as audio, as in the case of digital signal processing. It supplies to the part 7 and performs an audio | voice output.

  By the way, terrestrial television broadcasting is currently broadcast in a state where terrestrial analog broadcasting and terrestrial digital broadcasting are mixed. However, in 2011, terrestrial analog broadcasting will be stopped, and after that, it will be decided that only terrestrial digital broadcasting will be integrated. From the standpoint of effective use of broadcast radio waves when such terrestrial analog broadcasting is stopped, the arrangement of broadcast channels for terrestrial digital broadcasting, where broadcasting continues, is completely reviewed or aggregated within a specific frequency band. Planning to use the vacant frequency band for other purposes other than broadcasting (for example, a mobile phone) is progressing.

  Here, a television broadcast receiver capable of receiving both terrestrial analog broadcasts and terrestrial digital broadcasts has a unique function as described below, compared to a terrestrial analog broadcast dedicated receiver or the like.

  In other words, a television broadcast receiver capable of receiving both terrestrial analog broadcast and terrestrial digital broadcast has a significantly different internal operation program than a dedicated analog broadcast receiver, and performs a much larger amount of software processing. It has a function. For example, when performing channel selection processing of a terrestrial digital broadcast signal, frequency information about each digital broadcast, program information of each program, and the like are superimposed and arranged in the digital broadcast as digital data. When a channel is selected, the digital data is separated from the digital broadcast and the contents are analyzed. Also, with regard to the encryption / decryption processing for viewing restriction currently being carried out on almost all programs, the encryption / decryption processing is always continued while the program is being viewed. In addition, most of the user interface such as program reservation processing and menu screen, the interface with externally connected devices, and peripheral functions are realized by software processing.

  On the other hand, in the case of selecting a terrestrial analog broadcast signal, not a few software processes are required, including a user interface such as a menu screen. And when terrestrial analog broadcasting is stopped, it is no longer necessary to perform software processing related to analog broadcast tuning, so if you disable the function of software processing related to terrestrial analog broadcasting tuning, Therefore, the software processing burden is reduced, and at the same time, the effect of reducing power consumption can be obtained.

  In the following, the process of disabling software processing when terrestrial analog broadcasting is canceled will be described using the flowchart shown in FIG.

  First, in step S1, the television broadcast receiver is turned on, and the television broadcast receiver is activated to enter an operating state.

  Next, in step S2, the control unit 8 determines whether or not a terrestrial analog broadcast processing stop request has been output. When it is determined that a terrestrial analog broadcast processing stop request has already been output (Y), the process proceeds to the next step S3, while it is determined that a terrestrial analog broadcast processing stop request has not yet been output ( N), the process proceeds to another step S4. In this case, the terrestrial analog broadcast processing stop request is stored as a flag in the software processing, and can always be referred to during the software processing. When this terrestrial analog broadcast processing stop request has been issued, an operation program for processing is selectively disabled for each processing block in order to skip all processing related to channel selection for terrestrial analog broadcasting. Is provided with a branching process.

  Next, in step S3, if the terrestrial analog broadcast processing stop request is not output, that is, if the reception of the terrestrial analog broadcast is continued without stopping the terrestrial analog broadcast, the control unit 8 The broadcast processing unit enters a skip state without performing any processing. Normal reception processing is performed as in the previous state.

  Subsequently, in step S4, the control unit 8 performs reception processing of both terrestrial analog broadcasting and terrestrial digital broadcasting, that is, normal reception processing, as in the previous state.

  As described above, according to the television broadcast receiver according to this embodiment, the software processing is invalidated when the terrestrial analog broadcast is stopped. Thus, the software processing burden can be reduced correspondingly, and at the same time, the power consumption of the television broadcast receiver can be reduced as compared to before the broadcast is stopped.

  Moreover, in the television broadcast receiver of the present invention, a television broadcast receiver that exhibits the following functions is formed as a second example of this embodiment. In other words, the terrestrial TV broadcast listening area is a mixture of terrestrial analog broadcasting and terrestrial digital broadcasting, and those broadcast channels broadcast within the same frequency band (for example, UHF band) are transmitted to the ground. Although it is received by a tuner for digital broadcasting, at the time of reception, the terrestrial analog broadcasting and the terrestrial digital broadcasting give the same channel interference or adjacent channel interference to the intended broadcast reception signal. . For this reason, the tuner for digital terrestrial broadcasting performs digital signal level adjustment at the tuner input unit when receiving digital broadcasts. When it is determined that the target broadcast reception signal is inferior due to the bit error rate or the like due to the interference, the amplification amount of the tuner input unit is reduced to reduce the influence of the interference wave.

  However, if the amount of amplification at the tuner input unit is reduced, the performance of the received digital broadcast is also reduced. This occurs when it cannot be received in good condition.

  In order to avoid the occurrence of such a situation, in the second embodiment, when a terrestrial analog broadcast and a terrestrial digital broadcast are mixed as a broadcast reception tuner control program used for a television broadcast receiver. Both the control program used and the control program used when only terrestrial digital broadcasting is stored, and when it is detected that the terrestrial analog broadcasting has been stopped, the terrestrial digital broadcasting until then The function of the tuner control program used in the above is disabled, the function of the tuner control program that is optimally set for receiving digital terrestrial broadcasting is enabled, and then the enabled control program is used. This makes it possible to improve the reception performance of digital broadcasting.

  In general, in digital terrestrial broadcasting, date information is superimposed on a digital broadcast radio wave to be transmitted, and usually a reservation function or the like is realized using this date information. For this reason, in this embodiment, by using this date / time information for the arrival of terrestrial analog broadcasting at the time of cancellation, the date / time information is simply incorporated into the control program without adding hardware. Can detect when analog wave broadcasting is stopped. Incorporation of the date and time into the control program may be performed before shipment of the television broadcast receiver, or the date and time may be incorporated by a user through a menu operation.

  Moreover, in the television broadcast receiver of the present invention, a television broadcast receiver that exhibits the following functions can be formed as a third example of this embodiment. That is, when the arrival of the terrestrial analog broadcast at the time of cancellation is detected by the date / time information incorporated in the control program or the setting of the date / time in the built-in timer, the control unit 8 outputs a terrestrial analog broadcast processing stop request. In addition, the operation of components directly related to analog broadcast reception is stopped, and the function of the control program of the tuner is changed as described above to improve the reception performance of digital broadcast.

  Next, a method of using the menu screen when outputting a terrestrial analog broadcast processing stop request from the control unit 8 will be described.

  FIG. 3 is an explanatory diagram illustrating an example of a user operation screen displayed on the video display unit 6 of the television broadcast receiver.

  As shown in FIG. 3, the display screen 13 includes three selection information blocks 14, 15, and 16 and a confirmation block 17. The selection information block 14 is a reception / selection information block for only terrestrial analog broadcasting. Reference numeral 15 represents reception of terrestrial analog broadcast and digital terrestrial broadcast, selection information block 16 relates to reception of only terrestrial digital broadcast, and confirmation block 17 represents selection OK.

  When this method is implemented, a menu screen is displayed on the video display unit 6 by a user operation, and reception of a desired terrestrial broadcast is selected using the display screen, and only a terrestrial analog broadcast is received. If the selection information block 14 is received, the selection information block 15 is received when both terrestrial digital broadcasting and analog terrestrial broadcasting are received, and any of the selection information block 16 is operated by remote control when only terrestrial digital broadcasting is received. When the selection block 17 indicating selection OK is selected in the same manner by remote control operation or the like, a tuner control program corresponding to the selected content is selected. At the time of selection, the function of the selected control program becomes valid, while the function of the non-selected control program becomes invalid. When the selection information block 16 is selected, the control unit 8 A terrestrial analog broadcast processing stop request is output.

  If the user selects reception of the desired terrestrial broadcast by a method of operating the display screen, for example, the reception of the terrestrial analog broadcast is received before the terrestrial analog broadcast is stopped. It is possible to improve the reception performance of digital broadcasting by stopping the entire operation.

  Next, a description will be given of a method for detecting a stop point of analog broadcasting based on automatic detection of a channel being broadcast when outputting a terrestrial analog broadcast processing stop request from the control unit 8.

  In general, a terrestrial broadcast receiver has a function that enables a desired broadcast to be received by automatically detecting a broadcast channel and assigning it to a remote control key, that is, a search function. In addition, there is a receiver that performs a search operation periodically by back processing in the terrestrial broadcast receiver even when no user operation is performed. This method uses such a function, and when the control unit 8 detects that the terrestrial analog broadcast is stopped, it outputs a terrestrial analog broadcast processing stop request, and is directly related to the terrestrial analog broadcast as described above. In this method, the function can be realized only by software processing without adding hardware.

  In this case, when the control unit 8 detects the cancellation of the terrestrial analog broadcasting, the control unit 8 can immediately achieve the processing invalidation of the components directly related to the terrestrial analog broadcasting. By notifying the user of cancellation of terrestrial analog broadcasting using a function, etc., at that time, using the menu screen, realizing the processing invalidity of the components directly related to terrestrial analog broadcasting or postponing the processing invalidation, etc. You may make it choose.

  Next, one method for improving the reception performance of digital broadcasting in a television broadcast receiver after achieving processing invalidation of components directly related to terrestrial analog broadcasting will be described as follows.

  When the terrestrial analog broadcast is stopped, the components directly related to the terrestrial analog broadcast in the TV broadcast receiver have been disabled, and are allocated to receive the terrestrial analog broadcast channel before that. Remote control keys are wasted. Therefore, as another example of this embodiment, other functions are assigned in advance to the remote control keys assigned to terrestrial analog broadcast channel reception, and the control unit 8 at the time when terrestrial analog broadcast is stopped. When the remote control key is detected, it is effective without causing unnecessary use of the remote control key by controlling the remote control key so that other functions assigned in place of the reception of the terrestrial analog broadcast channel can be realized. It becomes possible to use.

  For example, when a dedicated number key is assigned to each channel of terrestrial analog broadcasting, when the terrestrial analog broadcasting is stopped, each of those number keys is transferred to other broadcast media, for example, For example, dedicated allocation to BS broadcasting, CS broadcasting, CATV, and the like. In this case, since the corresponding number keys are for multiple channels, if the user selects the desired channel of the desired broadcast media directly, the convenience for channel selection is improved for the user. .

  Further, another method for improving the reception performance of the digital broadcast in the television broadcast receiver after achieving the processing invalidation of the components directly related to the terrestrial analog broadcast will be described as follows.

  In this method, when the terrestrial analog broadcast is stopped and the components directly related to the terrestrial analog broadcast are disabled, only the terrestrial analog broadcast in the menu screen 13 shown in FIG. Since there is no need to select the selection information block 14 used for reception, there is no point in displaying the selection information block 14 on the menu screen 13 as a user interface, and the display is omitted. It is. That is, the current television broadcast receiver is compatible with terrestrial digital broadcasting, and the operation program for displaying it is very complicated such as layering the menu screen 13. Here, by omitting the display of the selection information block 14 related to the analog broadcasting, not only the convenience for the user is greatly improved, but also the operation program is simplified. Also in this method, when the display of the selection information block 14 is omitted, after the user is automatically notified using a notification function or the like, the display may be erased by the user's selection operation.

It is a block diagram which shows the principal part structure of the television broadcast receiver concerning embodiment of this invention. It is a flowchart which shows the process background when invalidating software processing at the time of cancellation of terrestrial analog broadcasting. It is explanatory drawing which shows an example of the user operation screen displayed on the video display part of a television broadcast receiver.
