【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a television broadcasting apparatus, a television broadcasting receiver, and a television signal recording / reproducing apparatus according to one embodiment of the present invention.
[0016]
In FIG. 1, reference numeral 1 denotes a television broadcasting apparatus, and 2 denotes a television broadcasting receiver and a television signal recording / reproducing apparatus. Reference numeral 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 conversion device, 8 is a program information superposition device, and 9 is a transmission antenna. is there.
[0017]
10 is a receiving antenna, 11 is a receiving circuit, 12 is a program information separating 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 discriminating device, 19 is a second program information memory, and 20 is a program selecting device.
[0018]
The operation is described below. First, the video and audio to be broadcast are input to the video signal input terminal 3 and the audio input terminal 4 of the television broadcasting device 1. These signals are input to the broadcast signal generation device 5, and a broadcast signal is generated from the input video and audio. The program information input from the program information input terminal 6 is signalized by a program information signal conversion circuit 7 and superimposed on a broadcast signal by a program information superimposition device 8. At this time, as a method of superimposing program information on a television broadcast signal, in a conventional analog television broadcast, for example, similar to a method already practiced in a text broadcast, program information is written during a horizontal / vertical retrace period. For this purpose, a specific period may be provided, and the program information may be superimposed in that period.
[0019]
In digital television broadcasting, this can be easily realized by inserting the program information as information bits into information blocks in a bit stream. The broadcast signal on which the program information is superimposed is broadcast from the transmission antenna 9.
[0020]
Next, in the television broadcast receiver and the television signal recording / reproducing device 2, the broadcast is received by the receiving antenna 10 and the original video and audio signals are restored by the receiving circuit 11. Further, the program information separating 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 microcomputer 16 displays the information stored in the first program information memory 15 when necessary, selects a program on the screen by the program selection device 20, The channel control circuit 14 allows the user to select a station or make a reservation for recording on the VTR 17.
[0021]
The following is a detailed example of the program information. As the program information, the broadcast date and time, the broadcast time, the genre of the program, and the name of the program are signalized and transmitted.
[0022]
As the time at which the program information is sent, for example, the program information for one day two weeks ahead of the day before and after the broadcast start time is sent together. That is, the broadcast time of the program information is slightly shifted from each channel, 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 taking in the program information 15, the program information up to two weeks ahead can always be stored. When the previously transmitted program information is changed, the broadcast station sends new information and rewrites the previous information so that the information becomes new, and information on an undecided program can be added.
[0023]
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 up to two months ahead. If program information is set to be transmitted several times a day other than before and after the broadcast start time, it is possible to obtain information on a program changed on the day. At this time, if program information is exchanged between the broadcast stations, it is possible to obtain program information of another broadcast station without changing the channel.
[0024]
As described above, the program information stored in the first program information memory 15 is displayed by the microcomputer 16 by switching the information such as the program currently being broadcast on a time-by-time, channel-by-channel or current broadcast basis to the receiver screen 13 as needed. Or it can be displayed by superimposition. Therefore, while viewing the screen, a program is selected by the program selecting device 20 such as a mouse or a key, and the selected program is stored in the first program information memory 15 to select a program or a program selection program. , Recording reservation can be easily made.
[0025]
In addition, while a normal program is being broadcast, information representing the program is superimposed and sent. This may be the remaining broadcast time, the genre of the program, the name of the program, and the like.
[0026]
As described above, when information of a program being broadcast is transmitted from a broadcasting station in a superimposed manner, for example, when performing a scheduled recording, the recording time is not controlled by the broadcast time of the program to be recorded, but is recorded. You can control the recording by name. Therefore, even when the information stored in the program information memory is changed immediately before the broadcast due to, for example, extension of the broadcast time of the previous program, the specified program can be accurately recorded.
[0027]
Also, if a program genre such as news or foreign film is specified instead of a program name, it is possible to automatically select a channel or automatically record at the same time that a program of that genre starts. it can.
[0028]
Further, the cassette currently set in the VTR 17 can be identified by the recording medium identification device 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 date and time of broadcast, the broadcast time, and the name of the program are transferred from the first program information memory 15 to the second program information memory 19 by the microcomputer 16 in correspondence with the respective cassette numbers. The information of the recorded program, such as the order of the cue signal (VISS or the like) within the program, can also be automatically sent to the second program information memory 19 and stored.
[0029]
With the above configuration, information such as the name of the program recorded in the cassette can be displayed on the receiver screen 13 simply by inserting the cassette, so that the contents of the cassette can be confirmed and the remaining tape amount can be calculated. Can be easily displayed.
[0030]
Conversely, from the information in the second program information memory 19, a desired program is searched from the recorded programs on the receiver screen, and the desired program is identified from the number such as the identification number of the cassette written on the bar code label. It is also possible to search for and specify a cassette in which the program to be recorded is recorded.
[0031]
In FIG. 1, the television broadcast signal is transmitted via the transmission antenna 9 and the reception antenna 10, but it may be transmitted via a satellite, via a satellite, or via a direct cable such as CATV. Good.
[0032]
Although a general VTR has been described as an example of a television signal recording / reproducing apparatus, a similar apparatus can be realized when another recording medium such as a video disk is used.
[0033]
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 have been described. However, among the functions of the above-described embodiments, those which selectively use necessary functions are also included in the present invention. included.
[0034]
【The invention's effect】
As described above, according to the present invention, program information is displayed on the screen of a television receiver by superimposing and broadcasting program information on a television broadcast signal and automatically obtaining the broadcast information on the receiving side.
