Features.

  With the above configuration, since another program list having a matching rate with a program that has failed to be reserved for recording is displayed at a predetermined level or higher, the user is the same as the program that has failed to perform scheduled recording based on the list. It becomes easy to make a new recording reservation for a program that seems to be.

  In the digital broadcast receiving apparatus configured as described above, the match rate of each selected program may be displayed on the list. Further, in the digital broadcast receiving apparatus having these configurations, a message indicating that the list of selected programs can be displayed is displayed, and the list is displayed when an operation for displaying the list is performed by the user. It may be configured.

  Further, the digital broadcast receiving apparatus having these configurations may be configured to select a processing mode in which the program selection process is continued based on newly acquired program information.

  Further, the digital broadcast receiving apparatus having these configurations may be configured to read out the program details of the program selected by the user from the programs on the list and display it. Further, the digital broadcast receiving apparatus configured as described above may be configured to newly make a recording reservation for a program selected by the user among the programs on the list.

  Further, the digital broadcast receiving apparatus having these configurations may be configured to automatically select a program from the programs on the list and execute reserved recording in accordance with preset conditions.

  According to the present invention, there is an effect that it is possible to take an appropriate response to the user when reservation recording fails.

  A digital broadcast receiving apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

  In FIG. 1, antennas 1A and 1B are arranged outdoors in a predetermined direction, and receive digital broadcast signals sent from satellites or terrestrial broadcast stations.

  The BS / CS digital tuner 2A and the terrestrial digital tuner 2B take out a signal of a specific frequency from the high-frequency digital modulation signal including video / audio data. Further, the tuners 2A and 2B include a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream. In this embodiment, the program recording by the other tuner can be performed while viewing the received program by one tuner.

  An MPEG-TS decoder separation circuit (hereinafter simply referred to as a decoder) 3 converts the transport stream into an MPEG2 (Moving Picture Experts Group 2) video stream, an audio stream, and PSI / SI (Program Specific Information / Service Information). To separate. The decoder 3 has an AV decoder unit that inputs a video stream and an audio stream. Further, the PSI / SI and the like are supplied to the CPU 13. As described above, a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from among the channels is determined from the PSI / SI in the transport stream. It becomes possible by taking out data such as whether the packet ID is multiplexed. In addition, a transport stream can be selected based on PSI / SI information.

  The AV decoder unit 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 to generate audio data. The video data is output to the video processing unit 4, and the audio data is output to the audio processing unit 5.

  The video processing unit 4 receives the video data of the received video, performs D / A conversion and down-decoding processing (for example, forms a frame in the memory 14), and converts it into, for example, a composite video signal. The video processing unit 4 has an OSD (on-screen display) function, and synthesizes video based on character information and color information instructed to be output from the CPU 13 with the video data. The audio processing unit 5 receives the audio data output from the decoder 3 and generates right (R) sound data and left (L) sound data.

  The video signal is supplied to the video output unit 11 through the amplifier 7. The audio data is converted into an analog signal through the D / A conversion amplifier 8 and input to the audio output unit 12. A display and a speaker (not shown) are connected to the video output unit 11 and the audio output unit 12 via an AV output terminal (not shown).

  The memory (RAM, EEPROM, flash memory, ROM, etc.) 14 stores program information (EPG data), various setting information set by the user, registered contents of recording reservation, and the like.

  The remote control transmitter 15 is a transmitter for sending a command to the broadcast receiving apparatus 30. When a key provided on the remote control transmitter 15 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The sub CPU 16 receives the signal light output when the key of the remote control transmitter 15 is operated, converts it into an electrical signal, performs code analysis, and gives a channel selection command or the like to the CPU 13.

  Further, the broadcast receiving apparatus 30 is provided with a memory card I / F (interface) 17, and the memory card 18 can be mounted via the memory card I / F 17. In addition, a USB I / F (interface) 19 is provided, and the USB memory 20 can be mounted via the USB I / F 19. A hard disk drive (HDD) 23 is installed. The received broadcast (partial transport stream, digital video / audio data) is stored (recorded) in the hard disk drive (HDD) 23.

  Further, the broadcast receiving apparatus 30 is provided with a LAN I / F (interface) 21, and the LAN card 22 can be mounted via the LAN I / F 21. By connecting to a site on the Internet via the LAN card 22, various information can be downloaded from this site.

  In addition to performing overall control of the broadcast receiving device 30, the CPU 13 and the sub CPU 16 execute reserved recording processing and processing when reservation recording fails as processing according to the present invention. The scheduled recording process determines whether or not the current date and time indicated by the internal timer is the reserved date and time based on a preset date and channel and when the current date and time is the reserved date and time (to the CPU 13 in the power-off state). When the power is not supplied, the sub CPU 16 activates the CPU 13), and instructs the tuner 2 to receive the reserved channel and records the received video / audio on the hard disk of the hard disk driver 23. Recording reservation can be performed by program designation on the EPG screen, bar code input, numerical value input, direct input, etc. Here, the program information of the recording reservation program (network ID, service ID, event_id, start time, program name) ) Is scheduled for recording. Program information of the scheduled recording program is stored in the memory 14 by the processing of the CPU 13. At the time of recording, program information is acquired from the received broadcast wave, and it is confirmed whether the program to be recorded has the same event_id as the reserved program. Then, when the start time is not changed and the event_id is the same, the reserved recording is executed. In addition, the program information can be acquired by directly entering the reservation date and channel information against the EPG data.

  By the way, when recording two programs that are close in time, if the preceding program is extended for a time exceeding the start time of the later scheduled recording program, the recording is extended according to the information indicating the extension. Under such a setting for extending the recording, the later scheduled recording program is not recorded and the recording fails. Also, recording fails when a power failure occurs during recording or when the main power is turned off. When the broadcast of the program itself is canceled (postponed), recording fails.

  As shown in FIG. 2, the CPU 13 creates a reservation execution result and displays the reservation execution result on the screen using the OSD function. In the example of the reservation execution result shown in FIG. 2, the broadcast type, channel number, date / time, program name, reason for failure, program candidate (list) that seems to be the same program, and matching rate are created for the program that has failed to be recorded. it's shown.

  In the example shown in FIG. 2, the reason for the failure is “the reservation was discarded because the previous program overlapped”. As described above, the reason for this failure corresponds to the case where the subsequent program cannot be recorded due to the recording extension of the preceding program. In addition to the above, the reason for the failure is that “recording could not be performed because it was not energized at the reservation date and time”. This reason for failure corresponds to a case where a power failure occurs during recording execution or the main power is turned off. In addition to the reasons described above, there are other reasons for failure, such as “The scheduled program could not be recorded because it was not broadcast”. This failure reason corresponds to the case where the program broadcast is canceled (postponed).

  The candidate of the program that seems to be the same program has, for example, a program name (title) and program content of 70% or more in proportion to the program name (title) of the program that failed to be recorded and the text of the program content. It can be obtained by searching for other programs based on the program information.

  If terrestrial broadcast viewing or recording is being performed, program information that can be newly acquired can be obtained only on the current channel. If terrestrial broadcast viewing is not being performed or recording is not being performed, program information can be acquired from each channel by sequentially switching terrestrial channels. It is possible to obtain program information of other channels on the reception channel even while watching or broadcasting a satellite broadcast wave. When the BS / CS digital tuner 2A and the terrestrial digital tuner 2B are provided as in this embodiment, the program information of other channels can be received by the BS / CS digital tuner 2A even during terrestrial broadcast viewing or recording. Obtainable. Further, even when a satellite broadcast wave is being viewed or recorded, program information for each channel of the terrestrial wave can be obtained by the terrestrial digital tuner 2B. If program information (EPG data) is provided at a specific site on the network, the program information can be acquired by accessing the site (URL is registered in advance).

  If a recording failure occurs during viewing of the broadcast, the reservation execution result may be displayed superimposed on the currently viewed video. If a recording failure occurs when the broadcast is not being viewed, the reservation execution result may be displayed on the screen when the first television is turned on thereafter. The reservation execution result may be displayed when a predetermined key provided on the remote control transmitter 15 is operated. Further, for example, a message such as “Do you want to see the reservation execution result” may be displayed first, and the reservation execution result may be displayed when a predetermined operation is performed by the user.

  In the example shown in FIG. 2, a button labeled “Monitor” is displayed. When a highlight (cursor) is placed on this button and the enter button is pressed, the broadcast receiving apparatus 30 continues to extract a program candidate that seems to be the same program based on the newly acquired program information. For example, the candidate extraction process is continued for the number of monitoring days set in advance on the menu screen (for example, 10 days). However, when a recording reservation is made for the program presented based on the monitoring result, the monitoring is performed. Stop monitoring even if days remain. Then, for example, the new reservation execution result is displayed on the screen at a certain time when the TV is ON or when the TV is ON, or when a new reservation execution result is created. Instead of displaying the new reservation execution result immediately, for example, a message such as “Do you want to see the monitoring result” is displayed, and the reservation execution result is displayed when a predetermined operation is performed by the user. It is good.

  The processing contents when recording fails can be selected in advance on the menu screen. Examples of this selection item include “automatic recording”, “display the reservation execution result and decide by the user”. Also, as the detailed setting of “automatic recording”, for example, “when recording overlaps with other reserved programs, priority recording of the recording failure program”, “when overlapping with other reserved programs, priority recording of other reserved programs is performed. And “Display confirmation message when overlapping with other reserved program”. Other detailed settings for “automatic recording” include, for example, “the program with the earliest start time”, “the program with the highest match rate”, and “the program with the match rate of 80% or more and the earliest start time”. There are items.

  For example, if “the other scheduled program is preferentially recorded when it overlaps with another reserved program” and “the program with the earliest start time” is selected, the earliest start time that does not overlap with another reserved program is the earliest. Schedules recording of programs automatically. Also, for example, when “a confirmation message is displayed when overlapping with another reserved program” and “a program with the earliest start time” is selected, a confirmation message is displayed when a program with the earliest start time overlaps with another reservation. Is displayed. For example, a message such as “Reservation of program A and program B has overlapped. Press 1 key to cancel the reservation of program A and press 2 key to cancel the reservation of program B” is displayed.

  For example, if “display the reservation execution result and the user decides” is selected, the reservation execution result is displayed on the screen. On the reservation execution result screen, for example, a highlight (cursor) is displayed (focused) on the uppermost candidate program by default. When detecting that the up / down key of the remote control transmitter 15 is pressed, the CPU 13 moves the highlight position up or down. Further, when detecting that the enter key is pressed, the CPU 13 performs processing for registering the program at the highlighted position as a reserved recording program. A display area may be formed at a predetermined position on the screen (a place other than the place where the highlight is displayed), and the program details of the focused program may be displayed in the display area. The program details can be read from the memory 14. Further, a button such as “Program Description” is displayed, and when it is detected that the button is operated, the CPU 13 may display the program details of the program focused on the area. By viewing the program details of the candidate program, the user can confirm whether the candidate program is the same program as the recording failure program. When the user determines that they are the same program, the user may make a recording reservation for the candidate program.

  Further, a button such as “To EPG screen” may be displayed on the reservation execution result screen. When this button is operated, the EPG screen is generated so that the program at the highlighted position is displayed in the approximate center of the screen. The user can check the program details of the program on the EPG screen to confirm whether the program is the same as the recording failure program. When the user determines that the program is the same program, the user may perform an operation for recording reservation of the candidate program on the EPG screen. The reservation execution result may be displayed on the screen with a mark indicating whether or not it overlaps with other reserved programs at each program location.
