Controls such as recording start and stop are performed.

Here, the program code to be input into the human input [5] is coded for each of a large number of programs, with a broadcast program content identification code, broadcast channel, broadcast date, broadcast start and end time, character data indicating the program content, etc. A set of program code data created by the broadcasting station 16, for example, is transmitted to each household using audio multiplex broadcasting means or broadcasting means that utilizes the gap band between frames in the TV broadcasting radio wave band. For antenna 13'! III broadcast,
It will be done. 15 is a broadcasting antenna. When the program code data 6 is broadcast, broadcast start code data and broadcast end code data for causing each injured device to detect the frame, the start of the broadcast of the program data 6, and the broadcast #1r are transmitted at the beginning and end of the broadcast. 14, a broadcast OjL reception/reproduction section receives and reproduces the 11 normal broadcast waves, and also receives and reproduces the transmitted program data signal and inputs it to the input section 5 as program code data 6.

Further, the first reviewer search device 1 is installed so that the program code data 6 is stored in the data storage section 3 in a self-manufactured manner when the program code data 6 is broadcast. For this purpose, the program search device 1 automatically sets a data input mode WAK during a predetermined program code data broadcast time period. Next, FIG. 2 is a conceptual diagram showing an example of program code data. 201

Broadcast programs are categorized by content, such as Nice, weather forecasts, baseball, pop songs, movies, medicine, education, agriculture, etc., and are coded into dozens of types.

As described above, with the configuration shown in FIGS. 1 and 2, K performs program search processing for broadcast program information by specifying program contents.
First, the friend program code data 6 created in advance at the broadcasting station 16 is received by each viewer from the broadcasting antenna 14 using, for example, audio multiplex broadcasting means or broadcasting means that uses the radio wave band in the gap between frames. It is broadcast to the antenna 13 at any time (for example, weekly iIf, 5-minute transmission in the morning, etc.). The program code Cheataro input to the broadcast radio wave reception/reproduction unit 14 is input to the microcomputer 7 via the input unit 5, and under the control of the microcomputer 7, the program code data 6 is generated by detecting the broadcast start code data. is stored in the data storage s3, and the input ends when the broadcast end code data is detected. At this time, the old program code data 6 previously stored in the data storage section 3 is erased and updated on the new program day in the evening.

Thereafter, program search processing such as a search based on program content specification can be executed. To execute the search, the user operates the keyboard 2 to input a broadcast program content identification code corresponding to the specified content into the microcomputer 7, and searches the program code data 6 group stored in the data storage section 3. As a result of the search, six groups of program code data having identification codes that match the identification code specified by the keyboard 2V are extracted, and based on the coded data of each of the six extracted groups of examiner code data, Under the processing of the computer 7, output data 8 and a control signal 9 for controlling the peripheral device 1 (TV, VTft, etc.) are outputted via the output unit 1O.

Here, when the search data is displayed by the television set 11, the data codes of the six groups of program code data searched and output are decoded, and the front line of the scent sentence expressing the program content, the broadcast date and time, etc. Broadcast channels, etc. are displayed on the screen using letters, numbers, etc. Also, when controlling the output data 8 and control signal 9 searched and outputted from the VT le 12 to perform automatic recording according to the program content specification, the microcomputer 7 searches and extracts it by matching the program content specification code. The data codes of the six groups of program code data are decoded, and the broadcast date, broadcast start time, broadcast end time, etc. are compared point by point with the current day 1 o'clock data input from the clock section 4. That #I! As a result, the day we matched,
At times, control signals 9 such as a broadcast channel selection command, recording start, and stop recording are applied to the VTR 12, and a television program with specified program content is automatically recorded 4.

According to the broadcast program search processing system of the present invention, broadcast program information can be searched by program content.

For conventional viewers, the drawbacks are that they tend to become passive due to the hassle of selecting programs, and continue to tune in to TV or radio, overlook expensive programs, or fail to record them. There is one nine.

By solving this drawback, it becomes extremely easy to select and search program information, and it becomes possible to make detailed use of broadcast information.

Furthermore, since the broadcast program code data stored in the broadcast program search processing system of the present invention is automatically divided into four sets by the broadcast of the program code data from the broadcast station, the viewer has no need to input the data. It eliminates the hassle of reading program guides published in newspapers, magazines, etc., and eliminates the hassle of reading VT)L.
This frees you from the complexity of time settings and the like when making scheduled recordings.

In this embodiment, a device incorporating the broadcast wave receiving/reproducing section 14 has been described, but a means for substituting the broadcast wave receiving/reproducing section 14 by a television receiver, a VTR, etc. is also implemented.

Further, the present invention is not limited to television or radio program search processing, but can be implemented for general information processing of broadcast programs such as optical communication broadcast programs and cable broadcast programs.
