  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a broadcast receiving apparatus 30 of this embodiment capable of viewing both terrestrial digital broadcasting and terrestrial analog broadcasting.

  In FIG. 1, an antenna 1 is arranged outdoors in a predetermined direction, and receives a terrestrial broadcast wave transmitted from a terrestrial broadcast station.

  A digital tuner module (in this embodiment, used for ATSC (Advanced TV System Committee) and receives aerial waves) 2 extracts a signal of a specific frequency from a high-frequency digital modulation signal including video / audio data. Further, the digital tuner module 2 includes a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  The demultiplexer (DEMUX) 3 separates and decodes the transport stream into MPEG2 (Moving Picture Experts Group 2) video stream, audio stream, PSI / SI (Program Specific Information / Service Information), and the like. The demultiplexer 3 supplies the video stream and the audio stream to the AV decoder 4 and supplies the PSI / SI to the CPU 13.

  Further, the demultiplexer 3 separates a program clock reference (PCR) from the transport stream and supplies it to the clock generator 26. The clock generator 26 generates a reference clock (27 MHz) necessary for video decoding based on the PCR.

  The AV decoder 4 includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. The video decoder decodes the input variable length code to obtain a quantization coefficient and a motion vector, and performs inverse DCT conversion, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input encoded signal (main audio or one or more sub-audios) to generate audio data.

  The selector 19 selects either the video data based on the digital broadcast output from the AV decoder 4 (including its synchronization signal) or the video data based on the analog broadcast output from the NTSC decoder 18 (including the synchronization signal). To the video processing circuit 5. On the other hand, the selector 25 is for an analog signal, and selects either an analog audio signal output from the audio signal processing circuit 6 or an analog audio signal output from the analog tuner 17 and supplies the selected audio signal to the audio output circuit 8.

  The video processing circuit 5 receives the video data and the synchronization signal, performs D / A conversion to generate a video signal (composite signal, component signal, etc.), and provides this video signal to the video output circuit 7. The audio processing circuit 6 receives the audio data output from the AV decoder 4, performs D / A conversion, and generates an analog audio signal.

  The video output circuit 7 and the audio output circuit 8 include an output resistor, an amplifier, and the like. The AV output terminal 9 is provided with an output unit (a set of left and right audio output terminals and video output terminals). The monitor 24 connected to the AV output terminal 9 includes, for example, an image receiving unit including a deflection circuit 22 and a high voltage circuit 23 for driving the cathode ray tube 21, a speaker 20, and the like. In the case of a wall-mounted broadcast receiver, a liquid crystal panel or a plasma display may be provided instead of the cathode ray tube 21. In the case of a stationary type, it may be configured as a rear projector or the like.

  An analog tuner module (for NTSC in this embodiment) 17 performs a channel selection process for selecting a signal having a frequency corresponding to a channel selected by the user, a process for demodulating the signal having the selected frequency, and the like. Signals and analog audio signals are generated.

  The NTSC decoder 18 includes an A / D conversion circuit, etc., digitizes the analog video signal received from the analog tuner module 17, generates video data in the same format as the video data output from the AV decoder 4 and synchronizes with it. A signal is generated and supplied to the selector 19.

  The OSD (On Screen Display) circuit 12 outputs bitmap data based on the character information instructed to be output from the main CPU 13 to the adder 16. The adder 16 performs processing for incorporating the bitmap data into the video data output from the selector 19. The OSD circuit 12 displays a menu screen, a character screen during on-timer processing, and the like.

  The memory 14 (RAM, ROM, EEPROM, flash memory, etc.) stores various programs, program information, various setting information (on-timer setting information, etc. described later) and the like.

  The main CPU 13 controls channel selection commands and channel search for the digital tuner module 2, controls writing / reading of various data to / from the memory 14, controls the demultiplexer 3 (including switching control), and the AV decoder 4. Control for the OSD circuit 12, switching command for the selectors 19 and 25, control for the modem 27, control of the memory card loaded in the slot 28, control of the interface (IEEE 1394 interface, etc.), communication with the sub CPU 15 And so on.

  The remote control transmitter 10 is a transmitter for sending a command to the broadcast receiving device 30. The remote control transmitter 10 includes various keys. When such a key is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The remote control light receiver 11 receives the signal light, converts it into an electrical signal, and gives it to the sub CPU 15.

  The sub CPU 15 inputs a remote control signal from the remote control transmitter 10 or a control signal by a key operation of an operation unit (not shown) and notifies the main CPU 13 and controls the analog tuner module 17.

  When the operation content for the remote control transmitter 10 or the like relates to analog broadcasting, the main CPU 13 knows this by the notification and causes the sub CPU 15 to execute necessary processing.

  The modem 27 operates under the control of the main CPU 13 in dial-up connection or interactive service communication when transmitting viewing history information to the billing center. Further, the CPU 13 is connected to the Internet via the modem 27, and the user can download desired video data and music data from a specific or arbitrary site to the receiving device 30. The CPU 13 can output the downloaded video and / or audio in an on-timer process to be described later. Details thereof will be described later.

  The slot 28 is loaded with a memory card (not shown). The CPU 13 can output video and / or audio read from the loaded memory card in an on-timer process to be described later. The CPU 13 can also record video and / or audio acquired by broadcast reception on a memory card.

  For example, a DVD player or the like is connected to the interface (for example, IEEE 1394 interface) 29, and the CPU 13 can cause the DVD player or the like to execute a reproduction operation via the interface 29. Then, the CPU 13 can output video and / or audio obtained by DVD reproduction in an on-timer process described later. The CPU 13 can also record video and / or audio acquired by broadcast reception on a DVD player or the like.

  Next, the on-timer function provided in the broadcast receiving apparatus 30 will be described.

  As shown in FIG. 2, an on-timer setting menu is prepared as a menu, and the on-timer can be set on this menu screen. Specifically, it is possible to set on time, channel setting, and whether to use video and / or audio stored in the memory card on this menu screen. When a still image is selected, the still image playback setting can be selected, and single playback or slide show can be selected.

  When single playback is selected, the CPU 13 accesses the memory card inserted in the card slot 28, searches for a file that can be played back a still image, and displays the file names in a predetermined order (eg, filed date order). To do. At this time, the video of the selected file may be displayed on the screen as a single image or a thumbnail image may be displayed. The left and right keys (cross key) provided on the remote control transmitter 10 are used to select the files to be displayed in order, and the file to be used is determined using the enter key.

  When the slide show is selected, the CPU 13 accesses the memory card inserted in the card slot 28, searches for a folder in which a file that can be played back still images is stored, and is in a predetermined order (such as the order of file date). The folder name is displayed in. At this time, a representative file video (such as the most recently saved file video) of the selected folder on the screen may be displayed as a single image or a thumbnail image may be displayed. Select the files displayed in order, and decide the file to use with the enter key.

  When a moving image is selected, the CPU 13 accesses the memory card inserted in the card slot 28, searches for a file that can be reproduced as a moving image, and displays the file names in a predetermined order (such as the order of file date). At this time, the selected file image may be reproduced and displayed on the screen. When a moving image is selected, “sound is used” is automatically set (a process for making arbitrary designation impossible is performed). In addition, the repetition time can be set. The repetition time is to set the length of one repetition of video and audio. In FIG. 2, the selection is made from 10 seconds, 30 seconds, and 60 seconds, and the cursor is placed at a desired location (second). Can be set by pressing the Enter key. Further, an arbitrary time may be set by operating a numeric keypad of the remote control transmitter 10.

  When “use voice” is set, the CPU 13 accesses the memory card inserted in the card slot, searches for a playable file, and plays the voice in a predetermined order (eg, filed date order). Displays the file name. At this time, the sound of the selected file may be reproduced. Also, the repetition time can be set. The repetition time is to set the length of one voice to repeat. In the example, it is selected from 10 seconds, 30 seconds, and 60 seconds. Place the cursor on the desired location (seconds) and press the enter key. It can be set by pressing. Further, an arbitrary time may be set by operating a numeric keypad of the remote control transmitter 10. The volume can also be set, and the set volume may be dedicated when the on-timer is activated.

  When “Video: Still Image” and “Audio: Not Use” are set in the on-timer setting menu, the receiving device 30 is set with the file (folder) set for the video when activated by the on-timer. Playback is performed by the method (single playback or slide show), and the sound is output as the sound obtained by receiving the broadcast of the set channel (in the case of default, it may be the last channel, for example). When “video: still image” and “sound: use” are set, the receiving device 30 is set to a method (single playback) in which a file (folder) set for video is set when activated by the on-timer. Or a slide show), and the file set for the audio is played with the set repetition time and volume. When “video: video” is set, the receiving device 30 plays back the audio and video of the set file with the set repetition time and volume when activated by the on-timer.

  Hereinafter, the operation of the CPU 13 will be described by taking as an example the case where the settings of “video: still image” and “sound: use” are performed.

  The CPU 13 determines whether or not the current time has reached the set time by using its own internal clock (timer), and turns on the power of the receiving device 30 when the current time has reached the set time. At that time, the content of the on-timer setting stored in the memory 14 is checked. In this case, since the settings are “video: still image” and “sound: use”, the tuners 2 and 17 are energized. No (or no video and audio from broadcast reception even if energized). Based on the content, the CPU 13 accesses the memory card inserted into the card slot 28 and reads the data of the designated video and / or audio file. At this time, the CPU 13 controls the AV decoder 4 to cause the AV decoder 4 to process the signal from the memory card, and further controls the selectors 19 and 25 to send the signals from the memory card to the video output circuit 7 and the audio output circuit 8. To supply. Further, the CPU 13 sets the volume of the volume circuit in the audio output circuit 8 based on the content. Thereby, the signal from the memory card is converted into a digital video signal (for example, JPEG) and a digital audio signal (for example, PCM) by the AV decoder 4. Then, the video signal is input to the video output circuit 5 through the selector 19 to be converted into an analog signal, whereby the designated video is displayed on the screen of the monitor 24. The audio signal is converted into an analog signal by the audio output circuit 8, and the designated audio is output from the speaker of the monitor 24 through the selector 25.

  The video and audio output states according to the setting contents are canceled when the remote control transmitter 10 or the main body side button is pressed.

  In addition to recording video and audio acquired by an external device (for example, a digital camera), the memory card can also record video and audio acquired by broadcast reception by the receiving device 30. In addition, video and audio acquired by broadcast reception by the receiving device 30 can be recorded in the built-in memory 14. Hereinafter, a video and audio recording method acquired by broadcast reception will be described.

  FIG. 3 shows an on-timer video / audio recording menu. In video recording, a still image or a moving image can be selected.

  Processing when “still image” on the menu is selected will be described. As shown in FIG. 3A, the user selects “still image” on the menu and then returns to the normal video display state. In this normal display state, for example, when the CPU 13 detects that a still button provided in the remote control transmitter 10 is pressed, the screen image is stopped (drawing of a new decoded image in the VRAM is stopped), and thereafter When the pressing of the still button is detected, processing for returning to the moving image output state is performed (video decoding is resumed). When the CPU 13 detects pressing of the enter button in the screen still state, for example, the CPU 13 filings still image data on the VRAM into the memory 14 as on-timer video / audio.

  A process when “moving image” on the menu is selected will be described. As shown in FIG. 3B, the user selects “moving image” on the menu and then returns to the normal video display state. When “moving image” is selected, the memory audio item cannot be selected. In a state where this “moving image” is selected, when the CPU 13 detects that the blue button of the remote control transmitter 10 is pressed, the CPU 13 starts recording moving image / audio data by broadcast reception in the memory 14 or the like from this detection time point. When the yellow button is detected, the recording is terminated. Then, when the CPU 13 detects that the determination button has been pressed thereafter, the CPU 13 performs processing for converting the video / audio temporarily recorded in the memory 14 or the like into the video / audio for the on-timer.

  Next, an audio recording process when “still image” on the menu is selected will be described. As shown in FIG. 3C, the user selects “memory audio” on the menu and then returns to the normal video display state. In a state where this “memory audio” is selected, when the CPU 13 detects that the blue button of the remote control transmitter 10 is pressed, the CPU 13 starts recording audio data by broadcast reception in the memory 14 or the like from this detection time. Recording is terminated when a button press is detected. Then, when the CPU 13 detects that the determination button has been pressed thereafter, the CPU 13 performs processing for converting the sound temporarily recorded in the memory 14 or the like into the sound for the on-timer.

  FIG. 4 shows an example of an on-timer setting menu when recording audio / video data as video / audio for the on-timer in the built-in memory 14.

  The audio / video data output when the receiving device 30 is activated by the on-timer is not limited to the data stored in the memory card or the built-in memory 14. The receiving device 30 of this embodiment includes an interface 29 and can control driving of an external device such as a DVD player. Therefore, for example, in the on-timer setting menu shown in FIG. 2, an item such as a DVD image may be prepared, and a still image or a moving image obtained by DVD reproduction, and further, audio may be output when activated by the on-timer.

  In addition, the past video / audio obtained by broadcast reception is output at the time of activation by an on-timer. However, the past video / audio obtained by broadcast reception is not limited to that of a normal program, and data broadcasting It may be a video based on data obtained by receiving. For example, if the on-timer is set at 7:00 am, the tuner is automatically activated at around 6:30 am 30 minutes ago to receive the weather forecast data broadcast and store the weather data. Keep it. After data acquisition, turn off the tuner. At 7 am, an on-timer is started, the weather data is read from the memory, and characters, characters, and animation are displayed on the screen using the OSD function. Audio can also be obtained from data broadcasting. In addition, based on the data addressed to each device (for example, fortune-telling data if a contract for fortune-telling is distributed) by an EMM (Entitlement Management Message) message, characters, characters, and animations are displayed on the screen using the OSD function. To do. Delivery of the EMM message is performed, for example, at around midnight.

  The video / audio output at the time of startup by the on-timer may be video / audio downloaded from a specific or arbitrary site using the Internet function. For example, if one minute is required for downloading, the file transfer function is automatically activated approximately one minute before the set time of the on-timer and based on the date of birth provided to the site in advance from a specific site The fortune-telling moving image (or still image) and sound of the day are downloaded and stored in the memory. When the on-timer setting time is reached, a fortune-telling image is displayed on the screen, and sound is output from the speaker.

  The acquisition of video / audio via the Internet, data broadcasting, etc. may be prepared in the menu items as in FIG. In this case, it is preferable that the user can arbitrarily input a URL or a data broadcast channel number.

  When the repetition time set on the menu screen elapses, video / audio by normal reception of the channel set on the menu screen is output. Also, even before the repetition time elapses, when a button operation of the remote control transmitter 10 (it is not necessary to turn on the button) is detected, video / audio by normal reception of the channel set on the menu screen is output. It is good to do.

  In the above-described embodiment, it is possible to perform setting for outputting video and / or audio of media other than broadcast when the on-timer function is turned on, or video and / or audio acquired by past broadcast reception. Outputs a video and / or audio of media other than broadcast or a video and / or audio acquired by receiving a past broadcast when receiving an ON command by the first remote controller operation in a predetermined time zone Settings may be made. For example, when the first on operation is performed by the remote control transmitter 10 between 6:00 am and 8:00 am, the weather forecast and news video acquired by data broadcasting and the music selected by the user are output, For example, when the first on-operation is performed by the remote control transmitter 10 between 6:00 pm and 8:00 pm, the video / audio read from the memory card may be output.

  In the above embodiment, the broadcast receiving apparatus is shown as a set-top box. However, the broadcast receiving apparatus may be a stationary or wall-mounted broadcast receiving apparatus with a built-in reception function.
