However, in the conventional CM program broadcasting system, when an unpredictable happening occurs in the program on the HE side, the CM program is suddenly inserted or the length of the CM program is changed. If you want to do so, it is very difficult to make extreme changes because of the involvement of NET stations. This problem is increasing proportionately as the number of NET stations increases and the involvement with each local NET station increases. Further, in the NET station, it is necessary for an operator to select a CM program corresponding to predetermined program transmission data and transmit a CM program for each channel at an appropriate timing. As the number of broadcasting stations on the HE side increases, the number of operations performed by operators of NET stations increases dramatically, and there is a problem that costs such as personnel costs increase proportionally.

The present invention has been made to solve the above-mentioned conventional problems. The HE can control the timing and length of a CM program, select a CM program at a NET station, and select a CM program. An object of the present invention is to provide a CM program automatic reproduction / transmission system that can automate transmission.

It is. In the broadcasting system on the HE side 10, a video signal is output from the program transmission device 14 to the character signal multiplexing device 13, and the video signal is output from the character signal multiplexing device 13 to the transmission unit 15 and transmitted. Also, from the CM data signal production device 11, C
The M data signal is output to the teletext program transmission device 12. When the CM data signal is input, the teletext program transmission device 12 outputs the teletext program data to the text signal multiplexing device 13. In the teletext signal multiplexing device 13, when the teletext program data is input, the teletext program data is multiplexed during the vertical blanking period of the video signal, output to the transmitting unit 15, and transmitted from the transmitting unit 15. It is sent to the NET station.

[0007] In the NET station 20, the video signal transmitted from the HE side 10 is received by the receiving section 21 and output to the CM data signal detecting section 22. The CM data signal detector 22 outputs the input video signal to the broadcast signal mixer 26 and outputs a CM data signal multiplexed to the video signal to the CM data signal processor 23. CM
The data signal processing unit 23 outputs the CM data information to the CM program combination selecting unit 24 when the CM data signal is input. When the CM data information is input, the CM program combination selecting section 24 outputs the CM program combination data to the CM program reproducing device 25. When the CM program combination data is input, the CM program reproducing device 25 receives, for example, a CM 15 second program 28, a CM 30 second program 29, a C
It reproduces the M60 second program 30 and outputs the television signal to the broadcast signal mixer 26. The broadcast signal mixer 26 selects the video signal input from the CM data signal detector 22 and the television signal input from the CM program reproducing device 25 and outputs the selected signal to the transmitter 27. Sent to the machine.

Next, a processing procedure for transmitting a CM data signal on the HE side according to the present embodiment will be described in detail with reference to a flowchart of FIG. First, S110 indicates that the HE side 10 is in a state during the program broadcast time. That is,
The television image signal is output from the program transmission device 14 to the character signal multiplexing device 13 (S160). Next, S12
0, the program production side such as the director determines whether or not to insert a CM program, and if the CM program is not inserted (S120: N
o) is only to output the television video signal from the program transmission device 14 to the character signal multiplexing device 13 (S16).
0). Then, when the video signal is input, the character signal multiplexing device 13 converts the 0000 4-bit digital signal into a 4-bit digital signal, which is text broadcast program data, from the text broadcast program transmitting device 12. The video signal is multiplexed with a scanning line not used for a predetermined teletext during a vertical blanking period of the video signal and output to the transmission unit 15 (S150). Next, the transmitting unit 15 transmits the input video signal to each NET station (S170).

[0009] If the program production side such as the director determines in S120 that a CM program is to be inserted (S120: Ye
s), when the data information of the start and end and the length of the CM program is input to the CM data signal production device 11 by the operation of the operator, the CM data signal production device 11
A CM start data signal indicating the start of the program, a CM end data signal indicating the end of the CM program, and a CM length data signal indicating the length of the CM program are output to the teletext program transmission device 12 (S130). . Next, the teletext program transmission device 1
Reference numeral 2 denotes a start, end, and length data signals of the input CM program, which are set in advance by a NET station side.
It is converted into a 4-bit digital signal which is program data. Then, as a signal to start transmitting the CM program data signal to the character signal multiplexing device 13, a 4-bit digital signal of 1111 is sent ten times, and the start, end, and length data of the 4-bit CM program are successively transmitted. A 4-bit digital signal is output continuously and repeatedly five times (S14).
0). Next, the teletext signal multiplexing device 13 outputs ten 11-bit 4-bit digital signals input from the teletext program transmitting device 12, followed by the 4-bit C signal.
A total of fifteen four-bit digital signals representing the start, end, and length data of the M program, one for each vertical blanking period of the input television video signal (S160),
The signal is multiplexed to a predetermined scanning line not used for teletext, and the multiplexed video signal is output to the transmitting unit 15.
Thereafter, until a 4-bit digital signal is input from the teletext program transmission device 12, the teletext signal multiplexing device 13
Multiplexes a 4-bit digital signal of 0000 on a scanning line that is not used for a predetermined teletext during a vertical blanking period of the input television image signal (S160) again, and transmits the multiplexed signal to the transmitting unit 15. Output (S150). Next, the transmitting unit 15 transmits the video signal input from the character signal multiplexing device 13 to each NET station (S170).

Next, C in the NET station side of this embodiment is
The processing procedure for transmitting the M data signal will be described in detail with reference to the flowchart in FIG. First, T110 is the NET station side 2
0 indicates that the receiving unit 21 is receiving the radio wave of the video signal transmitted from the HE side. The receiving unit 21 converts the received radio signal into a video signal and outputs the video signal to the CM data signal detecting unit 22. Then, the CM data signal detector 22
Detects the 4-bit digital signal multiplexed on a scanning line that is not used for a predetermined teletext during a vertical blanking period of the input video signal, and converts the digital signal into a CM data signal. At the same time as outputting to the processing unit 23, the video signal input from the receiving unit 21 is output to the broadcast signal mixer 26 (T120). When the 4-bit digital signal input from the CM data signal detector 22 is 4 bits of 0000, the CM data signal processor 23 determines that there is no CM data signal, and sends the CM program combination selector 24 Does not output a data signal (T
130: No). Therefore, in this case, the CM program is not reproduced. Next, the broadcast signal mixer 26 determines whether or not the television signal of the CM program is input from the CM program reproducing device 25. If the TV signal is not input (T180: No),
The video signal input from the M data signal detector 22 is output to the transmitter 27 (T200). The transmitting unit 27 transmits the video signal input from the broadcast signal mixer 26 to each television receiver (T210).

Further, the CM data signal processing unit 23
If the 4-bit digital signal input from the M data signal detector 22 is 1111 4-bit, it is determined that there is a CM data signal, and after receiving the 1111 4-bit digital signal 10 times, it is continued. The digital signal of the start, end, and length data of the CM program of 4 bits is continuously and repeatedly received five times, and the digital data of the start, end, and length data of each of the five CM programs is received. The signal is digitally encoded in 4 bits and stored in a memory. Then, the five stored 4-bit digital codes are compared, and if the five are the same, the 4-bit digital code is used as the digital code of each data.
If the stored five digital codes are not the same, majority is adopted and the largest number of digital codes is used as the digital code of each data. Then, the 4-bit digital code of each data is output to the CM program combination selecting section 24 (T140). Next, the CM program combination unit 24 starts and ends the CM program from the 4-bit digital code input from the CM data signal processing unit 23, based on the rule of the 4-bit digital code previously determined with the HE side. , Create each data of length. Then, based on the data of the start, end and length of the CM program, the optimum combination data of the CM program is selected from the CM program transmission data given in advance,
The combination data of the CM program is output to the program reproducing device 25 (T150). Next, the CM program reproducing device 25, based on the input combination data of the CM programs, receives a previously given CM 15 second program 28, CM 30
The CM programs are reproduced in the order of the combination of the CM programs from the second program 29 and the 60-second CM program 30 (T160), and the television signal of the reproduced CM program is output to the broadcast signal mixer 26 (T170). Next, the broadcast signal mixer 26 sets C
It is determined that the television signal of the CM program is input from the M program reproducing device 25 (T180: Yes), and the CM input from the CM program reproducing device 25 is replaced with the video signal input from the CM data signal detector 22. The television signal of the program is output to the transmission unit 27 (T190). Next, the transmission unit 27
The television signal of the CM program input from the broadcast signal mixer 26 is transmitted to each television receiver (T210).

[0012] Therefore, the HE side automatically inputs the data information of the start and end and the length of the CM program to the CM data signal producing device 11, thereby automatically setting the data information during the vertical blanking period of the television signal. CM data signals are multiplexed and transmitted to a NET station. The NET station processes the received data signals and reproduces / generates a given CM program based on the data information.
Transmission can be performed automatically. Therefore, HE
The side can insert a CM program at any time without considering the NET station side when unforeseen incidents occur, etc., and transmit the CM program without losing the structure of the program. It is possible to do. Further, the NET station side automatically combines a CM program given in advance in response to a CM program transmission request from the HE side and transmits the same, so that a CM program switching operation or the like by an operator is required. It is possible to reduce costs such as labor costs. Further, it is possible to easily cope with future multi-channel without increasing the number of operators and the like.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention. Good. (A) In this embodiment, three types of CM programs are prepared.
More CM programs with different broadcast times and the like may be prepared. (B) In this embodiment, only the video signal and the 4-bit digital signal are input to the character signal multiplexing device 13, but the character signal of the color still image information may be input simultaneously. (C) In the present embodiment, the 4-bit digital signal of 1111 indicating the start of the CM data signal is repeated 10 times from the teletext broadcast program transmission device 12 on the HE side to the text signal multiplexing device 13, and the start of the CM program is continued. , End, length 4
It is said that a digital signal of bits is output repeatedly five times in a row. If the reliability of video communication is high,
The number of times of sending each digital signal may be further reduced. If the reliability of the video communication is low, the number of times of transmitting each digital signal may be increased. (D) In the present embodiment, the CM data signal is a 4-bit digital signal. However, the number of bits of the digital signal may be larger, such as 8 bits, 16 bits, a synchronization code, a check code, or the like. The number of added bits may be used, and may be equal to or less than the number of bits of a character signal used for teletext. (E) In the present embodiment, the combination of the CM programs is selected on the NET station side based on three types of data information of the start, end, and length of the CM programs transmitted from the HE side. The combination of CM programs may be determined by a digital code such as 4 bits between the side and the NET station side. By doing so, it is possible to combine CM programs on the NET station side only by transmitting one type of combination data information from the HE side to the NET station.
