FIG. 2 is an explanatory diagram for explaining the occurrence of event relay and occurrence of reservation duplication in association with an electronic program guide. 9 is a flowchart illustrating a reservation execution process when a relay occurs.
[0016]
In FIG. 1, an antenna 1 is arranged outdoors in a predetermined direction, and receives a digital broadcast wave transmitted from a BS. The antenna 1 generally includes a frequency converter, and supplies a received / frequency-converted signal to a tuner 2.
[0017]
The tuner 2 extracts a signal of a specific frequency from the received high-frequency digital modulation signal. That is, a process of selecting one from a plurality of digital broadcast transponders is performed. Further, the tuner 2 includes a demodulation circuit, a deinterleave circuit, an error correction circuit, and the like, and thereby demodulates the selected digital modulation signal and outputs a transport stream.
[0018]
The demultiplexer (DEMUX) 3 separates the transport stream output from the tuner 2 into a video stream of MPEG2 (Moving Picture Experts Group2), an audio stream, a PSI / SI (Program Specific Information / Service Information), and the like. . The TS decoder 3a in the demultiplexer 3 extracts a transport stream (hereinafter, referred to as a partial TS) constituting the program selected by the user based on a command from the CPU 17, supplies the transport stream to the stream recording / reproducing unit 4, and supplies the AV stream to the AV decoder 7 Supplies a video stream and an audio stream. Note that a plurality of channels are multiplexed in the transport stream, and a process for selecting an arbitrary channel from among these is performed by selecting a packet ID in the transport stream from the PSI / SI. This is possible by extracting data such as whether the data is multiplexed. Further, the selection of the transport stream (the selection of the transponder) can also be performed based on the PSI / SI information. Further, the SI includes program information (program name, program start time, program continuation time, program content information, program genre information, etc.). These pieces of information are stored in a memory 18 described later by the CPU 17 and are used for EPG display, program reservation, and the like.
[0019]
The stream recording / reproducing unit 4 exchanges data and control signals with an external recording device (such as a hard disk or an MO, but in this embodiment, a D-VHS) 31 through the IEEE 1394 interface 5 and a TS decoder. The partial TS output from 3a can be written (recorded) to the external recording device 31, and the partial TS can be read from the external recording device 31 (reproduction). Of course, it may be recorded on a built-in hard disk (not shown) or the like.

The AV decoder 7 includes a video decoder that decodes a video stream and an audio decoder that decodes an audio stream. The video decoder decodes the input coded signal to obtain a quantization coefficient and a motion vector, and performs inverse DCT transform, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input coded signal to generate audio data.
[0021]
The video processing circuit 8 receives the video data from the AV decoder 7, performs D / A conversion, and converts the data into, for example, an NTSC composite signal. The audio processing circuit 9 receives the audio data output from the AV decoder 7 and performs D / A conversion to generate, for example, a right (R) sound analog signal and a left (L) sound analog signal.
[0022]
The video output circuit 10 and the audio output circuit 11 include an output resistor, an amplifier, and the like. The AV output terminal 12 is provided with an output unit (a set of left and right audio output terminals and a video output terminal), and a monitor 14 having a display and a speaker is connected to the output unit by a video / audio code 13. You.
[0023]
The OSD circuit 19 outputs to the adder 20 bitmap data based on the character information and color information instructed by the CPU 17 to output. The adder 20 performs a process of incorporating the bitmap data into video data. The OSD circuit 19 can display an EPG, a menu screen, various setting screens, and the like.
[0024]
The remote control transmitter 15 is a transmitter for sending a command to the broadcast receiving device 30. When a key (not shown) provided on the remote control transmitter 15 is operated, a 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 16 receives the signal light, converts the light into an electric signal, and supplies the electric signal to the CPU 17.
[0025]
The memory (for example, RAM, ROM, EEPROM, flash memory, etc.) 18 has program information, user setting information, programs executed by the CPU 17 (programs in a reservation duplication process described later), program reservation information (start time, end time). Time, reception channel, recording / viewing type information, priority order information used when a duplicate reservation is made, etc.) are stored.
[0026]
The CPU 17 performs overall control of the digital broadcast receiving apparatus 30. In particular, as processing according to the present invention, the CPU 17 performs program selection and reservation execution processing when broadcast times of reserved programs overlap. I have.
[0027]
The user operates the remote controller transmitter 15 to select, for example, an item of “priority setting at the time of overlapping reservations” from the menu screen to display the priority setting screen. On this screen, a plurality of program genres such as “sports, movies, dramas,...” Are displayed, and the user selects one of these genres and selects a priority (for example, 1st to 5th). Position). These pieces of user input information are stored as user setting information in the memory 18 by the CPU 17.
[0028]
When the user performs the program reservation process, the CPU 17 stores the reservation priority information determined based on the genre information of the program in addition to the start time and channel information in the memory 18 as the reservation information of the program.
[0029]
FIG. 2 is an explanatory diagram for explaining the occurrence of event relay and the occurrence of duplicate reservation in association with the electronic program guide. At the current time shown in this figure, the reservation reception process of the program A (A-1) of the channel 101 is being executed, and the reservation registration of the program B of the channel 103 starting at the time T which is the end time of the program A is not performed. It is what is being done. Here, when the information defining that the continuation (A-2) of the program A is to be broadcasted on the channel 102 at the time Z is received, the event relay is confirmed by the CPU 17 and the broadcast time of the program B and the continuation program A-2 is confirmed. Are detected to be duplicated.
[0030]
FIG. 3 is a flowchart for explaining a reserved program adjusting process when an event relay occurs. Here, the case where the recording reservation of the program is performed is described. While the program recording reservation is being executed (step S1), the CPU 17 obtains program information on the program and monitors whether an event relay has occurred (step S2). If no event relay has occurred, the end time of the current event (program) is monitored (step S3). If the end time has come, the process proceeds to step S10.
[0031]
If the occurrence of the event relay is confirmed (YES in step S2), the CPU 17 determines whether the broadcast time does not overlap with the existing reserved program (step S4). Proceed to step S8. When a reservation overlap with the existing reserved program is confirmed, a comparison process is performed between the reservation priority information held as the reserved program information of the program being reserved and the priority information held as the reserved program information of the existing reserved program. Is executed (step S5). When the CPU 17 determines that the priority of the existing program is high (YES in step S6), the CPU 17 sets the existing program as the next program (program to be reserved) (step S7), and determines that the priority of the relay program is high. Sometimes (NO in step S6), the relay destination program is set as the next program (step S8). Then, the end time of the current event is confirmed (step S9), and when the end time comes, the received program is switched to the next program (step S10).
[0032]
In the above flowchart, the program to be reserved is automatically switched, assuming that the recording of the program has been reserved. In the case of (video display state), when an event relay occurs and an overlap reservation is made, for example, "the broadcast time of program A and program B overlap. The reservation of program A with a higher priority order A message such as "Do you want to execute?" And a "YES / NO" button may be displayed on the OSD for a certain period of time so that the user can select a program. In this way, by presenting the reservation priority based on the genre information of the program, it is possible to assist the user in making a decision regarding the program selection. Further, since the user can select any program, it is possible to select a program (execute a reservation) reflecting the current intention of the user. If the user does not select a program within a certain period of time (eg, 5 to 10 seconds), a program with a higher priority is selected.
[0033]
If the priority of the overlapping programs cannot be differentiated due to the same genre, or if both of the overlapping programs are programs of a genre out of the priority order, the event relay destination is fixed. Or the reception of an existing reserved program may be prioritized.
[0034]
In addition to the event relay, the same processing may be performed when an overlap with an existing reserved program occurs due to a time extension on the same channel. Further, apart from these event relays and the like, when a program to be currently reserved overlaps with an existing reserved program, it is displayed which of the programs has a higher priority to assist the user in making a decision regarding the program selection. Can be. Further, for example, when the broadcast on the side where the reservation has been executed ends and the program on the side not selected as the reservation execution program has not ended, the remaining portion of the broadcast of the program is received (reserved) at this time. Execution).
[0035]
【The invention's effect】
As described above, according to the present invention, since the reservation priority of the program to be reserved can be set based on the genre information, it is possible to execute the reservation desired by the user.
