  In the broadcast receiving apparatus having these configurations, when the start time and the end time exist as the reservation conditions, the broadcast time of the program determined based on the program information is between the start time and the end time. If it is determined that the program exists, a message indicating that all the programs are reserved may be displayed on the screen on which the reservation condition is input.

  In the broadcast receiving apparatus having these configurations, when it is determined that there has been a change in the broadcast of the program, a screen for inputting the reservation condition is displayed, and information on the program reflecting the change on the screen is displayed. It may be displayed.

  According to the present invention, even when a so-called manual reservation is performed, it is possible to know information on a program that is a reservation target.

  Hereinafter, embodiments of the present invention will be described with reference to FIG. 1 to FIG. 5. Here, a case where BS digital broadcasting is received is illustrated. Of course, a receiving apparatus for receiving terrestrial digital, cable broadcasting, and Internet broadcasting can be used.

  FIG. 1 is a block diagram showing a digital broadcast receiving apparatus 30 of this embodiment. In FIG. 1, an antenna 1 is arranged outdoors in a predetermined direction, and receives a digital broadcast wave transmitted from a BS (Broadcasting Satellite). The antenna 1 generally includes a frequency converter, and supplies a received / frequency converted signal to the tuner 2.

  The tuner 2 extracts a signal having a specific frequency from the received high frequency digital modulation signal. That is, a process of selecting one from a plurality of transponders of digital broadcasting is performed. Further, the tuner 2 includes 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.

  The demultiplexer (DEMUX) 3 separates the transport stream output from the tuner 2 into MPEG2 (Moving Picture Experts Group 2) video stream, audio stream, PSI / SI (Program Specific Information / Service Information), and the like. . The TS decoder 3a in the demultiplexer 3 takes out the transport stream (partial TS) constituting the program selected by the user based on a command from the CPU 17 and supplies it to the stream recording / playback unit 4. Provide streams and audio streams. Note that a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from among these is the packet ID of the arbitrary channel in the transport stream from the PSI / SI. It becomes possible by taking out data such as whether or not it is multiplexed. Also, selection of a transport stream (transponder selection) can be performed based on PSI / SI information. Further, SI includes program information (program name, program start time, program duration, program content information, program genre information, etc.). And a program name, a broadcast date, program content information, etc. can be acquired by EIT (Event Information Table) in program information. Program information is stored in a memory 18 to be described later for the reserved program recording process.

  The stream recording / playback unit 4 exchanges data and control signals with the external recording device (D-VHS, hard disk, MO, etc.) 31 through the IEEE 1394 interface 5, and outputs the partial TS output from the TS decoder 3a. The external recording device 31 can be written (recorded), and the partial TS and the like can be read from the external recording device 31 (reproduction). Of course, an internal recording device (such as a hard disk) (not shown) may be provided and recorded in this internal recording device.

  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 an input encoded signal to obtain a quantization coefficient and a motion vector, and performs inverse DCT transformation, 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 processing circuit 8 receives the video data from the AV decoder 7, performs D / A conversion, and converts it to, 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. The video output circuit 10 and the audio output circuit 11 include an output resistor, an amplifier, and the like, and supply the video signal and the audio signal to a monitor 14 including a display and a speaker.

  The OSD circuit 19 outputs bitmap data based on character information and color information instructed to be output from the CPU 17 to the adder 20. The adder 20 performs processing for incorporating the bitmap data into the video data. The OSD circuit 19 can perform EPG display based on SI received by the CPU 17, presentation of program information in manual 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 (not shown) 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 remote control light receiver 16 receives the signal light, converts it into an electrical signal, and gives it to the CPU 17.

  A memory (RAM, EEPROM, flash memory, etc.) 18 stores program information used for displaying an EPG, as well as various settings related to scheduled recording, which will be described later. It is also possible to provide an Internet connection environment, for example, to access a program information providing site, download program information, and record the downloaded program information in the memory 18. That is, the program information is not limited to being acquired by broadcast waves.

  The CPU 17 performs overall control in the digital broadcast receiving apparatus 30. In particular, as a control according to the present invention, a reserved recording process or the like is performed. As described above, EPG (electronic program guide) can be displayed based on program information (EIT, etc.), and the user can select a program to be reserved from the EPG.

  Furthermore, so-called manual reservation (reservation specifying the channel, date, start time and end time) can be performed. In this manual reservation, the CPU 17 acquires a program information acquisition unit that acquires program information from the memory 18 based on the channel, date, start time, and end time, and a program to be recorded based on the acquired program information. It functions as a presentation unit that presents information. If no channel is input, the current reception channel may be set as a recording target channel. If no date is input, today may be the recording date. When the start time is not input, for example, a time one hour later set in advance as a default may be set as the start time. In the case where the end time is not input, for example, the time may be set to a time after 3 hours (from the start time) set in advance as default.

  FIG. 2 is an explanatory view showing a manual reservation screen of this embodiment (showing a stage where no program information is presented). In this manual reservation screen, the user designates the channel, date, start time, and end time. Based on the channel, date, start time, and end time based on the manual reservation, the CPU 17 acquires information about the program that matches these, and the programs before and after that. Then, based on the information, for example, the horizontal axis is a time axis, the program sequence is shown along the time axis, and the reserved time zone is added with an image that is distinguished from others, and an image is generated. This is applied to the circuit 19. Thereby, as shown in FIG. 3, the indicator image in which the program arrangement and the reserved time zone are clearly shown is displayed on the display. In addition, you may employ | adopt the form which does not display the said program before and behind. In addition, you may display the information (program name etc.) of the said matching program irrespective of a time axis.

  Further, the CPU 17 determines whether or not the start time exists during the broadcast time of the program determined based on the program information. When it is determined that it exists (for example, program A), it is determined that recording is performed from the middle of the program A. Further, it is determined whether or not the end time exists during the broadcast time of the program determined based on the program information. When it is determined that the program exists (for example, the program D), it is determined that the recording ends in the middle of the program D. In addition, it is determined whether or not the broadcast time of the program determined based on the program information exists between the start time and the end time. When it is determined that it exists (eg, programs B and C), it is determined that all the programs B and C are recorded.

  With this processing, in the setting example of FIG. 3, the display such as “recorded program A from midway”, “all recorded program B”, “no recording halfway” is displayed.

  FIG. 4 shows a manual reservation screen when the user changes the end time to 11:20 during the reservation. In response to this change, the CPU 17 performs the above-described determination process again. In the setting example of FIG. 4, the display is “recorded program A from the middle”, “all recorded programs B and programs C”, and “recorded program D halfway”.

  FIG. 5 shows that the program (program C, D) scheduled to be broadcast from 11:00 to 11:30 on channel 101 after the manual reservation under the conditions of FIG. 4 is changed to another program (program F). The manual reservation screen (confirmation screen) is shown. The change of the program arrangement can be determined by PSI / SI. When such a change is made, a display such as “recorded program A from the middle”, “all recorded program B”, and “recorded program F halfway” is displayed. The CPU 17 may display the manual reservation screen shown in FIG. 5 when the change is determined. If the TV is OFF at that time, it may be displayed when the TV is ON. In addition, a message notifying the change may be displayed first, and the manual reservation screen may be displayed when the user performs an operation for requesting the manual reservation screen.
