The present invention relates to an information transmitting and receiving system, an information transmitting apparatus, an information receiving apparatus, and a method thereof. For example, the present invention relates to a receiver for receiving a broadcast wave sent from a broadcast station and displaying an image according to the broadcast wave on a monitor. It is suitable.

Conventionally, a broadcasting station which performs a broadcast service by analog terrestrial broadcasting has been allocated an available frequency band in advance, and transmits program data of its own station using the allocated frequency band. A receiver installed in the viewer's home (hereinafter referred to as an IRD (Integrated Receiver Decoder)) selects program data of a desired broadcasting station from among program data sent from each broadcasting station according to a tuning operation performed by the viewer. The program data of the broadcasting station is decoded and displayed on an external monitor.

(Tasks to be solved by the invention)

By the way, in the analog terrestrial broadcasting system, for the purpose of informing a viewer of programs provided from respective broadcasting stations, the contents of each program called electronic program guide information (hereinafter referred to as EPG (Electronic Program Guide) data) are described. It is proposed to regularly distribute data from specific broadcast stations. This EPG data consists of information such as a program title, a broadcast date and time, a broadcast channel, a description of a program, and the like, and serves as a judgment material when determining a program that a viewer watches.

In this case, the IRD receives the EPG data periodically sent from the broadcasting station that transmits the EPG data and stores it in the memory, and reads the EPG data from the memory and displays it on the external monitor in accordance with the display operation of the viewer. This allows the viewer to visually see the EPG data displayed on the monitor and decide which program to watch.

At that time, when the viewer performs the setting operation for the reserved recording for the desired program, the IRD stores the program information such as the broadcast date and time and the channel of the program in a nonvolatile memory, and enters the standby state for recording the program. The IRD is configured to execute a recording operation based on the program information stored in this nonvolatile memory, and to record the program desired by the viewer on the internal recording medium.

However, if the viewer forgets to set the recording medium at a predetermined position or to operate the reservation standby button for transitioning the IRD to the standby state after inputting the program information, for example, when performing the reservation recording setting operation, Viewers cannot record the program they want.

In this case, the viewer must search for a program rebroadcasted with the same contents as a program that could not be recorded from a vast number of programs included in the EPG data, and perform the setting operation of scheduled recording again for the retrieved rebroadcast program. It is still insufficient in terms of reducing the time taken for the setting operation of the reservation recording.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above points, and it is an object of the present invention to propose an information transmitting / receiving system, an information transmitting apparatus, an information receiving apparatus, and a method which can further improve the searching efficiency when searching for information.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, one Example of this invention is described in detail.

(1) Configuration of the analog terrestrial broadcasting system

In Fig. 1, 1 denotes a configuration of an analog terrestrial broadcasting system as a whole, and transmission apparatuses 2A to 2N provided in each broadcasting station transmit video and audio signals of a program to the transmission antennas 3A to 3N. Send each through. The relay device 4 relays the broadcast waves transmitted from the transmitters 2A to 2N, respectively, and distributes signals to receivers (hereinafter referred to as IRDs (Integrated Receiver Decoders); 5) installed in each viewer's house. do.

The IRD 5 receives, by the receiving antenna 6, broadcast waves which are each signal-distributed from a plurality of broadcasting stations, and among the program data of the plurality of broadcasting stations received by the viewer according to the tuning operation performed by the remote commander 7. The program data of the designated broadcast station is selected, and the program data of the selected broadcast station is demodulated and output to the monitor 8 as display means for display.

(2) configuration of IRD

As shown in FIG. 2, the IRD 5 receives the command signal S1 transmitted from the remote commander 7 (FIG. 1) superimposed on the infrared rays in the remote commander receiving section 10, and receives the command signal ( After converting S1) into an electrical signal to generate a command signal S2, it is sent to a CPU (Central Processing Unit) 11.

The CPU 11 reads the control program stored in the ROM (Read Only Memory) 12 as needed, transfers the read control program to the RAM (Random Access Memory) 13, and expands it. The CPU 11 controls each circuit of the IRD 5 by reading out and executing the control program developed in the RAM 13.

The CPU 11 analyzes the command signal S2 transmitted from the remote commander receiving unit 10, and as a result, when the viewer judges that the channel selection operation has been performed in the remote commander 7 (Fig. 1), the selected station is selected. A channel select signal S3 in accordance with the operation is generated and sent to the tuner 15.

The tuner 15 extracts the broadcast wave of the channel (broadcasting station) according to the channel selection signal S3 from the broadcast wave received by the receiving antenna 6 (Fig. 1), and demodulates the broadcast wave of the extracted channel. By this, the audio signal S5 and the video signal S6 are generated, and the audio signal S5 is transmitted to the audio processing unit 16, and the video signal S6 is sent to the video processing unit 17.

The speech processing unit 16 performs analog-to-digital conversion of the speech signal S5, compresses and encodes the result by the encoding method based on the Moving Picture Experts Group (MPEG) standard, and multiplies the resulting speech encoded data S7. The voice signal is sent to the voice decoder 19 through the separation unit 18. The image processing unit 17 performs analog-to-digital conversion of the image signal S6, and then compressively encodes the image signal S6 by using an encoding method based on the MPEG standard. The video decoder 20 transmits the video to the video decoder 20 through the video decoder 20.

The speech decoder 19 decodes and decodes the speech encoded data S7, and sends the resulting speech data S9 to the digital analog (D / A) conversion circuit 21. The D / A conversion circuit 21 restores the audio signal S10 before being input to the audio processing unit 16 by digitally analog converting the audio data S9, which is transferred to the monitor 8 (Fig. 1). Output

The video decoder 20 decodes and decodes the video encoded data S8, and sends the resulting video data S11 to the RGB encoder 22. The RGB encoder 22 generates the video signal S12 by converting the video data S11 into a luminance signal and a chrominance signal of the NTSC (National Television System Committee) system and digitally converting the analog signal. It sends out to FIG. 1).

In this way, the video of the program selected by the viewer is displayed on the display screen 8A of the monitor 8 (FIG. 1), and the audio of the program selected by the viewer is output from the speaker of the monitor 8.

By the way, in the analog terrestrial broadcasting system 1, description data of a program called electronic program guide information (hereinafter referred to as EPG (Electronic Program Guide) data) for the purpose of informing a viewer of a program provided from each broadcasting station. And to regularly distribute the signal from a particular broadcasting station.

This EPG data is generated for each program, and as shown in Fig. 3, a program-specific program ID (IDentification), a broadcast station number of a sender, a broadcast station name of a sender, a start time of a program, and a program length (or end time) , A program title, a program subtitle that supplements the program title, a program description, and a genre of the program, and are used as judgment material when determining a program to be viewed by the viewer. In addition, the program ID, broadcast station number, and genre are represented by code data. The broadcast station name, program title, program subtitle, and program description are represented by text data, and the start time and length are represented by time data.

The transmitter 2 provided in a specific broadcasting station superimposes EPG data for one week, for example, in the vertical blanking interval (VBI) of the video signal, for example, at night or early morning. Send regularly by time zone.

In this case, the tuner 15 of the IRD 5 extracts the broadcast wave of the channel in which the EPG data is overlapped among the broadcast waves received by the reception antenna 6 (Fig. 1), and selects the broadcast wave of the extracted channel. The demodulation generates a video signal S15 and sends it to the VBI slicer 25.

The VBI slicer 25 extracts the EPG data S16 from the video signal S15, transfers them to the RAM 13 via the bus BUS, and stores them. In this way, the IRD 5 updates the EPG data S16 stored in the RAM 13 every day, and always stores the latest EPG data S16 in the RAM 13.

In this state, when the viewer performs an operation for displaying the EPG screen in the remote commander 7 (FIG. 1), the remote commander 7 sends a command signal S1 for displaying the EPG screen to the remote commander receiving unit 10. To send). The remote commander receiving unit 10 converts this command signal S1 into a command signal S2 composed of an electric signal, and sends it to the CPU 11.

When the CPU 11 detects that the command signal S2 is supplied, the graphic processing of the EPG data S16 on the RAM 13 is performed on the RAM 13 based on dictionary data such as letters and symbols stored in the ROM 12. The EPG screen data S17 is generated by sending to the graphics engine 26 via the bus BUS.

The graphics engine 26 generates the EPG image signal S18 by converting the EPG screen data S17 into the luminance signal and the color difference signal of the NTSC system and digitally converting the analog signal, and sends it to the RGB encoder 22. do. The RGB encoder 22 mixes the video signal S12 and the EPG image signal S18 and outputs it to the monitor 8 (FIG. 1), and displays the EPG screen corresponding to the EPG image signal S18 of the monitor 8. It displays on the display screen 8A.

By the way, when the viewer performs an operation for recording the video and audio of the program in the remote commander 7 (Fig. 1), the remote commander 7 outputs a command signal S1 for performing the recording operation. To send). The remote commander receiving unit 10 converts this command signal S1 into a command signal S2 composed of an electric signal and sends it to the CPU 11.

When the CPU 11 detects that this command signal S2 is supplied, the CPU 11 controls the operation of each circuit via the bus BUS, thereby controlling the video of the program designated in the remote commander 7 (Fig. 1) and the like. It is made to record the voice. At this time, the multiplex / separator 18 is the speech coded data S7 obtained through the tuner 15 and the audio processor 16 sequentially, and the image coded data obtained through the tuner 15 and the image processor 17 sequentially. The multiplexed data (S8) is generated to generate the multiplexed data (S20), which is transferred to the recording media unit 30 and recorded in a built-in recording medium (not shown).

At that time, when the CPU 11 determines that the recording of the program designated by the viewer has ended, the CPU 11 is recorded in the recording media unit 30 based on the EPG data S16 stored in advance in the RAM 13. The recording title list data S21 which consists of a list of the titles of a program is generated and stored in the flash memory 31. FIG. The CPU 11 always stores the latest recording title list data S21 in the flash memory 31 by updating the recording title list data S21 each time a program is newly recorded in the recording media unit 30. It is made to

In this state, when the viewer performs an operation for displaying the recording title list screen in the remote commander 7 (Fig. 1), the remote commander 7 remotes the command signal S1 for displaying the recording title list screen. The command is sent to the command receiver 10. The remote commander receiving unit 10 converts this command signal S1 into a command signal S2 composed of an electric signal, and sends it to the CPU 11.

When the CPU 11 detects that the command signal S2 has been supplied, the CPU 11 transfers the recording title list data S21 to the RAM 13 and stores dictionary data such as letters and symbols stored in the ROM 12. Based on the graphics processing on the recording title list data S21 on the RAM 13, the recording title list screen data S22 is generated and sent to the graphics engine 26 via the bus BUS. .

The graphics engine 26 generates the recording title list image signal S23 by converting the recording title list screen data S22 into an NTSC luminance signal and a chrominance signal and digitally analog converting the same. To 22). The RGB encoder 22 mixes the video signal S12 and the recording title list picture signal S23 and outputs it to the monitor 8 (Fig. 1), and the recording title list screen according to the corresponding recording title list picture signal S23. Is displayed on the display screen 8A of the monitor 8.

Here, when the viewer visually sees the recording title list screen displayed on the display screen 8A of the monitor 8, and performs an operation for reproducing the video and audio of the desired program in the remote commander 7 (Fig. 1). The remote commander 7 transmits a command signal S1 for the reproducing operation to the remote commander receiving unit 10. The remote commander receiving unit 10 converts this command signal S1 into a command signal S2 composed of an electric signal and sends it to the CPU 11.

When the CPU 11 detects that this command signal S2 is supplied, the CPU 11 controls the operation of each circuit via the bus BUS, thereby controlling the video of the program designated in the remote commander 7 (Fig. 1) and the like. It is made to play the voice. That is, the recording media unit 30 reads out the multiplexed data S25 of the designated program from among multiplexed data of a plurality of programs recorded on the built-in recording medium (not shown), and sends it to the multiplex / separation unit 18. do.

The multiplex / separator 18 separates the multiplexed data S25 into speech encoded data S26 and video encoded data S27, and of these, the speech encoded data S26 is divided into speech decoder 19 and D / A. The conversion circuit 21 sequentially generates an audio signal S28 and outputs it to the monitor 8 (FIG. 1), and simultaneously outputs the image coded data S27 to the image decoder 20 and the RGB encoder 22. The video signal S29 is generated through this, and sent to the monitor 8.

In the CD-ROM (Compact Disc-Read Only Memory) 35, a face picture icon made up of a program logo of a base program and a face picture of a representative performer of the base program is stored, and is set in the CD-ROM decoder 36. The CD-ROM decoder 36 reads data of these program logos and face icon from the CD-R0M 35 as program association data (S35), which is associated with a program, and the flash memory via the CPU (11). It transfers to (31) and stores it.

(3) Reservation setting processing procedure of the program

Here, the reservation setting processing procedure at the time of scheduled recording of a program will be described. That is, when the viewer performs the setting operation of reserved recording for the desired program in the remote commander 7, the CPU 11 of the IRD 5 executes the reservation setting processing procedure RT1 of the program shown in FIG. do. In Fig. 4, when the CPU 11 enters the reservation setting processing procedure RT1 of the program, it moves to step SP1 and operates as a selection means, and reserves the broadcast date, channel, and program title of the reserved selected program. The memory is stored in the flash memory 31 as a standby state for recording the program.

Then, the CPU 11 moves to the subsequent step SP2 and operates as a recording control means for controlling the operation of each circuit based on the reservation program information stored in the flash memory 31 to perform the recording operation. At that time, it is judged whether or not the viewer desired program can be recorded in the recording media unit 30 as the detection means.

If an affirmative result is obtained in step SP2, this fact indicates that the viewer can record a desired program, and at this time, the CPU 11 moves to step SP3 to transfer the reserved program information to the flash memory 31. Delete from). In step SP4, the processing sequence ends.

On the other hand, if a negative result is obtained in step SP2, this fact indicates that the viewer could not record a desired program, and at this time, the CPU 11 moves to step SP5 to identify the reserved program information. A special symbol "re-" as information is added and stored in the flash memory 31.

In step SP6, the CPU 11 searches for a program identical to the program title indicated by the reserved program information among the vast number of programs included in the EPG data S16 stored in the RAM 13, and then continues. In step SP7, it is determined whether or not the corresponding program has been searched.

If an affirmative result is obtained in step SP7, this fact indicates that the same program as the program title indicated by the reserved program information is found in the EPG data S16, at which time the CPU 11 moves to step SP8. Then, it is determined whether the special symbol "re" is added to the reserved program information of the searched program.

If an affirmative result is obtained in step SP8, this fact indicates that a rebroadcast program having the same contents as the program that could not be recorded was found, and at this time, the CPU 11 moves to step SP9 and records. It operates as a control means, and stores the reserved program information of the program of the rebroadcast in the flash memory 31, reserves the program of the rebroadcast, and returns to step SP2 to record the program of the rebroadcast. Run

On the other hand, if a negative result is obtained in steps SP7 and SP8, this fact indicates that there is no rebroadcast program having the same contents as the program that could not be recorded in the EPG data S16. The CPU 11 moves to step SP10, determines whether the EPG data S16 stored in the RAM 13 has been updated, and repeats the processing step SP10 until an affirmative result is obtained. do.

If an affirmative result is obtained in step SP10, this fact indicates that the EPG data S16 stored in the RAM 13 has been updated, and at this time, the CPU 11 moves to step SP6, From the vast number of programs included in the updated EPG data S16, a program identical to the program title indicated by the reserved program information is searched for.

In this way, the CPU 11 repeats the above-described reservation setting processing procedure RT1 of the program, and when the program of the program title as shown in Fig. 5A cannot be reserved and recorded, for example, A program made by adding a special symbol "re" as shown in Fig. 5B is reserved for the program title.

(4) operation and effect of the embodiment

In the above configuration, when the reserved program is not recorded, the CPU 11 stores, as the retrieval key information, in the flash memory 31 that the special symbol "re" is added to the program title of the program. The CPU 11 then searches for a program formed by adding a special symbol "re" to the program title of the program from the EPG data S16 stored in the RAM 13.

As a result, the CPU 11 reserves the program when the rebroadcast program can be searched, and executes the search again when the EPG data S16 is updated when the program cannot be searched.

Thus, even if the reserved program cannot be recorded, the viewer does not have to search for a rebroadcast program having the same contents as the corresponding program in the EPG data S16, and further, such as setting a reserved program for the rebroadcast, There is no need to perform the operation either.

According to the above structure, when a reserved program is not recorded, the program which adds the special symbol "re" to the program title of the program in the EPG data S16 stored in the RAM 13 is searched. It is possible to search for a rebroadcast program having the same contents as a program that is not recorded, and to easily search for a corresponding program without setting the viewer's effort, and to perform reservation setting.

(5) another embodiment

In the above-described embodiment, when the reserved program is not recorded, a program formed by adding a special symbol "re-" to the program title of the corresponding program is searched among the EPG data S16 stored in the RAM 13; Although the case where the searched program is reserved is explained, the present invention is not limited to this, and information such as broadcast date, time, channel, program title, etc. of the searched program is displayed on the display screen 8A of the monitor 8.

For example, when two programs to be broadcasted in the same time zone are set for reservation, two of the EPG data (S16) can be set. The program of the rebroadcast of each of the three programs may be searched, of which the reservation of the program to be rebroadcasted early may be canceled, and the program of the rebroadcast of the released program may be newly reserved. In this way, duplication of reservation settings can be prevented without incurring viewers' efforts.

In the above-described embodiment, when a reserved program is not recorded, a program formed by adding a special symbol "re-" to the program title of the program is searched among the EPG data S16 stored in the RAM 13; Although the case where the searched program is reserved is explained, the present invention is not limited to this, and is stored in the RAM 13 when the program recorded in the recording medium unit 30 is erased by mistake. In the EPG data S16, a program formed by adding a special symbol "re-" to the program title of the program may be searched, and the searched program may be reserved.
