  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a television broadcast apparatus, a television broadcast receiver, and a television signal recording / reproducing apparatus according to an embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes a television broadcast apparatus, and 2 denotes a television broadcast receiver and a television signal recording / reproducing apparatus. 3 is a video signal input terminal, 4 is an audio signal input terminal, 5 is a broadcast signal creation device, 6 is a program information input terminal, 7 is a program information signal converting device, 8 is a program information superimposing device, and 9 is a transmission antenna. is there.

  Also, 10 is a receiving antenna, 11 is a receiving circuit, 12 is a program information separation circuit, 13 is a receiver screen, 14 is a channel control circuit, 15 is a first program information memory, 16 is a microcomputer, 17 is a VTR, 18 Is a recording medium discrimination device, 19 is a second program information memory, and 20 is a program selection device.

  The operation is described as follows. First, broadcast video and audio are input to the video signal input terminal 3 and the audio input terminal 4 of the television broadcasting apparatus 1. These signals are input to the broadcast signal creation device 5, and a broadcast signal is created from the input video and audio. The program information input from the program information input terminal 6 is converted into a signal by the program information signal converting circuit 7 and superimposed on the broadcast signal by the program information superimposing device 8. At this time, as a method of superimposing the program information on the television broadcast signal, in the conventional analog television broadcast, for example, the program information in the horizontal and vertical blanking period is the same as the method already in practical use in the character broadcast. For this purpose, a specific period may be provided, and program information may be superimposed on that period.

  Also, digital television broadcasting can be easily realized by inserting the program information as information bits into an information block in a bit stream. The broadcast signal on which the program information is thus superimposed is broadcast from the transmission antenna 9.

  Next, in the television broadcast receiver and the television signal recording / reproducing apparatus 2, the broadcast is received by the receiving antenna 10, and the original video and audio signals are restored by the receiving circuit 11. The program information separation circuit 12 separates the program information superimposed on the broadcast signal and stores it in the first program information memory 15. In addition to displaying the received broadcast on the receiver screen 13, the information stored in the first program information memory 15 is displayed by the microcomputer 16 when necessary, and the program is selected on the screen by the program selection device 20. The channel control circuit 14 can select a channel and make a recording reservation on the VTR 17.

  A detailed embodiment of program information will be described below. As program information, broadcast date and time, broadcast time, program genre, and program name are signaled and sent.

  As the time for sending the program information, for example, the program information for one day, two weeks ahead, before and after the broadcast start time is sent all at once. That is, the broadcast time of the program information is determined for each channel by slightly shifting, and the microcomputer 16 operates the channel control circuit 14 at that time to store the program information of each channel in the first program information memory. By performing the operation of fetching into the program 15, program information up to two weeks ahead can always be stored. Also, when program information sent before is changed, new information is sent from the broadcasting station side, and the information is renewed by rewriting the previous information, and information on an undetermined program can be added.

  Therefore, depending on the capacity of the program information memory, it is possible to store and display program information up to one month ahead and two months ahead. Further, if it is determined that program information is sent at several times a day other than before and after the broadcast start time, it is also possible to obtain information on the program changed on that day. At this time, if program information is exchanged between the broadcasting stations, it is possible to obtain program information of other broadcasting stations without changing the channel.

  As described above, the program information stored in the first program information memory 15 is displayed by the microcomputer 16 by appropriately switching the information such as the program currently being broadcast for each hour, each channel, and the like on the receiver screen 13 when necessary. Or it can be displayed by superimposing. Accordingly, by selecting a program by the program selection device 20 such as a mouse or a key while looking at the screen and storing the selected program in the first program information memory 15, it is possible to select a program or to select a program. Recording reservation can be performed easily.

  Further, while a normal program is being broadcast, information representing the program is superimposed and sent. This may be the remaining broadcast time, program genre, program name, and the like.

  As described above, when information on a program being broadcast is transmitted from a broadcasting station, the program to be recorded is not controlled by the broadcast time of the program to be recorded, for example, when performing scheduled recording. You can control the recording with the name. Therefore, even when the information stored in the program information memory is changed immediately before the broadcast, for example, by extending the broadcast time of the previous program, the designated program can be recorded accurately.

  For example, if a program genre such as news or a foreign movie is specified instead of specifying a program name, it is possible to automatically select a channel or record automatically when a program of that genre starts. it can.

  Further, the cassette currently set in the VTR 17 can be discriminated by the recording medium discriminating apparatus 18 having a configuration in which a bar code reader is attached to the cassette insertion portion of the VTR 17 and a bar code sticker is attached to the cassette body. Therefore, the broadcast date / time, broadcast time, and program name are transferred from the first program information memory 15 to the second program information memory 19 by the microcomputer 16 in correspondence with the number of each cassette. The recorded program information such as the order of the cueing signals (VISS etc.) can be automatically sent to and stored in the second program information memory 19.

  With the above configuration, information such as the names of programs recorded in the cassette can be displayed on the receiver screen 13 simply by inserting the cassette, so the contents of the cassette can be confirmed and the remaining tape amount can be calculated. Can be displayed easily.

  Conversely, the desired program is retrieved from the recorded program on the receiver screen from the information stored in the second program information memory 19, and the desired number is determined from the number such as the cassette identification number written on the bar code sticker. It is also possible to search and specify a cassette in which a program to be recorded is recorded.

  In FIG. 1, the television broadcast signal is transmitted via the transmitting antenna 9 and the receiving antenna 10, but it may be broadcast by connecting directly with a cable such as satellite broadcasting via a satellite or CATV. Good.

  Further, although a general VTR has been exemplified as a television signal recording / reproducing apparatus, a similar apparatus can be realized when other recording media such as a video disk are used.

  In addition, as an embodiment according to the present invention, a receiver and a television signal recording / reproducing apparatus having a large number of functions are mentioned. However, among the functions of the above-described embodiments, those that selectively use necessary functions are also described. Included in the invention.

  The television receiver according to the present invention is useful as a digital television or the like.
