Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a broadcast program recording / reproducing apparatus used for broadcasting a sports program being recorded, for example, a broadcast program transmitting method of the broadcast program recording / reproducing apparatus, and a broadcast program transmitting system using the broadcast program recording / reproducing apparatus. .
[0002]
[Prior art]
As is well known, for example, in a broadcasting system that broadcasts a sports program, the sports program is recorded on a tape of a VTR (Video Tape Recorder), and the program data to be broadcast is recorded in another VTR from the recorded program data. Dubbing on tape.
[0003]
By the way, in such a broadcasting system, even if the recording time of a sports program and the broadcasting time of this recorded program overlap, it is necessary to broadcast the recorded program without interruption. In such a case, conventionally, recording of a program is performed by a plurality of VTRs. In other words, a program is recorded by one VTR at the start of recording of the program, and editing is performed by extracting the broadcast part from the program data recorded on the tape of the VTR being recorded a predetermined time before the broadcast start time of the program. , This editing result is dubbed to another tape. During this editing operation, the program recording process is continued using one of the remaining unused VTRs. Such editing work is repeated for each VTR until the program to be recorded is completed.
[0004]
[Problems to be solved by the invention]
However, in such a conventional method, since most of the work from recording a program to editing and broadcasting the program to be broadcast is manually performed, it takes a lot of time and effort to edit the program and also causes human error. It's easy to do. For this reason, editing work immediately before broadcasting cannot be performed.
[0005]
Further, as the recording time of the program and the time overlapped with the broadcasting time of the recorded program become longer, the number of VTRs increases, and the number of operators who operate the VTRs also increases. For this reason, operation costs and labor costs required for program editing also increase. Furthermore, since it is necessary to edit CM (commercial) in the program to be broadcast, much work is required for editing.
[0006]
An object of the present invention is to allow a single device to quickly and appropriately edit recorded program data used for broadcasting regardless of the overlap of the recording time of the recorded program and the broadcast time of the recorded program. It is an object of the present invention to provide a broadcast program recording / reproducing apparatus, a broadcast program transmitting method of the broadcast program recording / reproducing apparatus, and a broadcast program transmitting system capable of reducing cost and labor on the operator side.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured as follows.
The broadcast program recording / playback apparatus according to the invention of (1) is in a state in which program data of a first time length is recorded in the first storage means on the basis of control from an external control device provided outside. The present invention is intended for a broadcast program recording / reproducing apparatus that generates program data stored in the first storage means into program data having a second time length shorter than the first time length and sends it as a broadcast signal.
Then, a plurality of broadcast component data to be used for broadcasting is extracted as the second time-length program data from the first time-length program data stored in the first storage means, and identification information representing these broadcast component data Each of the first storage means storing the first instruction information for indicating the storage area of the first storage means storing the data of the transmission start point and the storage area of the first storage means storing the data of the transmission stop point. In response to a reproduction command signal including a second storage means for storing second instruction information for instructing and an address for specifying a storage area of the first storage means provided from the external control device, Broadcast component data is read out from the storage means and transmitted as a broadcast signal, and reading of the broadcast component data from the first storage means is stopped in response to a reproduction stop command signal. The second instruction information corresponding to the broadcast component data and the first instruction information corresponding to the broadcast component data to be read next are read from the second storage means based on the read state of the data and sent to the external control device A reproduction control means for providing a reproduction command signal to the reproduction control means based on the first instruction information, and a reproduction stop instruction for the reproduction control means based on the second instruction information. A signal is given.
[0008]
According to the invention of (1), a single device having a memory capable of independently writing and reading information is used, and the program data of the first time length recorded in the memory is recorded. A plurality of broadcast component data to be used for broadcasting is extracted from the inside, and the broadcast component data is associated with the first and second instruction information, so that the broadcast in the readout state is based on the readout state of the broadcast component data. The second instruction information corresponding to the component data and the first instruction information corresponding to the broadcast component data to be read next are transmitted to the external control device.
[0009]
Therefore, the external control device can grasp the transmission start timing and the transmission stop timing of the broadcast component data based on the first and second instruction information, and based on the grasped result, the reproduction command signal and the reproduction stop command A signal can be sent arbitrarily. Therefore, the operator only extracts a plurality of broadcast component data from the first time-length program data recorded in the memory and registers the first and second instruction information in association with the broadcast component data. Thus, there is no need to rewind the recorded tape or to copy the broadcast component data to another tape, thereby greatly reducing the operational burden in program editing and broadcasting. In addition, since the time required for program editing is shortened, it is possible to edit programs even immediately before broadcasting, and it is possible to prevent the occurrence of operation mistakes and to perform accurate and reliable program editing and broadcasting. Become.
[0010]
(2) It further includes time information acquisition means for acquiring time information, and third storage means for storing information indicating the broadcast start time and information indicating the broadcast end time of the second time-length program data, and reproduction control The means compares the time information acquired by the time information acquisition means with the information indicating the broadcast start time and the information indicating the broadcast end time stored in the third storage means, respectively, and based on the comparison result, the broadcast start time The broadcast start is instructed to the external control device before a predetermined time, and the broadcast control is instructed to the external control device a predetermined time before the broadcast end time.
[0011]
According to the invention of (2), time information obtained separately by preparing a memory storing information indicating the broadcast start time and information indicating the broadcast end time of the second length of program data to be broadcast. And the information indicating the broadcast start time and the information indicating the broadcast end time stored in the memory are respectively determined to determine a predetermined time before the broadcast start time and a predetermined time before the broadcast end time. Based on this, the broadcast start instruction information and the broadcast end instruction information are respectively transmitted to the external control device.
Accordingly, the broadcast start time and broadcast end time of the program data being recorded are determined by the own apparatus, so that the processing load on the external control apparatus can be kept low.
[0012]
(3) The broadcast program recording / playback apparatus according to (1) above, a program playback apparatus for sending second program data independent of the first program data sent by the broadcast program recording / playback apparatus, and a broadcast program Based on the changeover switch for selectively deriving one of the output of the recording / reproducing apparatus and the output of the program reproducing apparatus as a broadcast signal and the first instruction information output from the broadcast program recording / reproducing apparatus, the program reproducing apparatus The playback stop command signal is given to the broadcast program recording / playback device, and then the changeover switch is switched from the output of the program playback device to the output of the broadcast program recording / playback device and output from the broadcast program recording / playback device. Based on the second instruction information, a playback stop command signal is given to the broadcast program recording / playback device, and a playback command signal is given to the program playback device, and then the broadcast program recording / playback device outputs It is obtained so as to include a program switching controller for switching the output of Luo program playback apparatus.
[0013]
According to the invention of (3), the first and second instruction information is transmitted from the broadcast program recording / playback apparatus to the program switching control apparatus, and the program switching control apparatus uses the first and second instruction information. Thus, either one of the output of the broadcast program recording / playback apparatus and the output of the program playback apparatus is automatically sent out as a broadcast signal.
Therefore, for the operator of the program switching control device, it is only necessary to set the transmission timing of the first program data and the transmission timing of the second program data in advance in the program switching control device in advance, which greatly increases the labor. It becomes possible to reduce.
[0014]
(4) The broadcast program recording / reproducing apparatus sends the transmission instruction information for transmitting the second program data to the program switching control apparatus together with the first and second instruction information when the first and second instruction information is transmitted. Switching instruction information output means for outputting is provided.
According to the invention of (4), the operator of the broadcast program recording / playback apparatus can judge and instruct the broadcast timing of the second program data by itself, thereby the second program data between the broadcast component data. Can be broadcast arbitrarily.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a broadcast program transmission system according to an embodiment of the present invention.
In the system of FIG. 1, a program server 11, a CM server 12, a switcher 13, and an automatic program transmission control device (APC) 14 are connected to the bus 10.
[0016]
The program server 11 records the program data to be broadcast, reproduces the recorded program data based on the reproduction command signal from the automatic program transmission device 14, and outputs it to the switcher 13. Further, the reproduction of the program data is stopped based on the reproduction stop command signal from the automatic program sending device 14. The CM server 12 records CM (commercial) data to be broadcast, reproduces the recorded CM data based on a reproduction command signal from the automatic program transmission device 14, and outputs it to the switcher 13. The output of the program server 11 and the output of the CM server 12 are selectively derived by the switcher 13 and thereafter transmitted as a broadcast signal. The automatic program transmission control device 14 performs switching control of the switcher 13 after transmitting a reproduction command signal or a reproduction stop command signal to the program server 11 and the CM server 12 according to the broadcast schedule data. In addition to the output of the program server 11 and the output of the CM server 12, the automatic program transmission control device 14 performs transmission control and switching control of other program data.
[0017]
FIG. 2 is a block diagram showing the configuration of the program server 11.
In FIG. 2, an input interface (I / F), a CPU 113, a program data memory 114, an instruction information memory 115, a broadcast schedule memory 116, a bus I / F 117, and an output interface (I / F) 118 are connected on the data bus 111. Is done.
[0018]
The program data being recorded input from the input interface 112 is sequentially stored in the program data memory 114 by the CPU 113. The CPU 113 notifies the terminal 119 of program data stored in the program data memory 114 in response to a request from the terminal 119. Then, the roll data identification information edited for broadcasting by the terminal 119 is stored in the instruction information memory 115, and the transmission start point data is stored in association with the roll data identification information. The transmission start instruction information for indicating the area of the program data memory 114 and the transmission stop instruction information for indicating the area of the program data memory 114 in which the data of the transmission stop point are stored are stored. An example of the stored contents is shown in FIG.
[0019]
Further, the CPU 113 reads out the roll data stored in the program data memory 114 when a reproduction command signal from the automatic program transmission control device 14 coming via the bus interface 117 is input during recording of the program data. Output via the output interface 118. At this time, the CPU 113 monitors whether or not the read roll data reaches the transmission stop point, and before a predetermined time before reaching the transmission stop point, the transmission stop instruction information corresponding to the roll data and the next The roll data transmission start instruction information to be read is read from the instruction information memory 115 and transmitted to the automatic program transmission control device 14 via the bus interface 117. The reproduction command signal includes an address for specifying a storage area of roll data to be read from the program data memory 114. Further, the CPU 113 stops the roll data reading process when a playback stop command signal from the automatic program transmission control device 14 that arrives via the bus interface 117 is input.
[0020]
As shown in FIG. 5, the broadcast schedule memory 116 stores data indicating the broadcast start time and the broadcast end time given from the automatic program transmission control device 14. The CPU 113 compares the time counted by the timer 15 with the broadcast start time and broadcast end time stored in the broadcast schedule memory 116, and based on the comparison result, a predetermined time before the broadcast start time (about 3 seconds before). At the same time, instruction control (TAKE control) is performed on the automatic program transmission control device 14, and TAKE control is performed on the automatic program transmission control device 14 a predetermined time before the broadcast end time.
[0021]
Next, the operation according to the above configuration will be described.
Here, when a soccer game is recorded, the soccer game is scheduled for 2 hours from 15:00 to 17:00, for example, but the broadcast time is 1:30 from 16:00 to 17:30. Suppose there was. The program data of the soccer game being recorded is transmitted from the VTR camera being recorded to the broadcast station and transferred to the program server 11 in the broadcast station. In the program server 11, program data that has arrived via the input interface 112 is stored in the program data memory 114 by the CPU 113.
[0022]
When a program data editing request comes from the terminal 119, the CPU 113 notifies the terminal 119 of the program data stored in the program data memory 114. At this time, the automatic program transmission control device 14 notifies the CPU 113 of the format data of the program shown in FIG. 6A, and the CPU 113 notifies the terminal 119 of the format data. The operator of the terminal 119 extracts the roll data to be used for broadcasting from the notified program data, and performs processing for inserting the roll data into the main part of the format data as shown in FIG. At the same time, the roll data transmission start point and transmission stop point are specified. Then, the CPU 113 stores the format data edited by the terminal 119 in the broadcast schedule memory 116, and designates the specified roll data transmission start point instruction information and the transmission stop point instruction information as roll data identification information. The instructions are stored in the instruction information memory 115 in association with each other.
[0023]
Then, the CPU 113 performs TAKE control on the automatic program transmission control device 14 approximately 3 seconds before the broadcast start time (16:00) stored in the broadcast schedule memory 116, and starts the control process shown in FIG. .
When this control process is started, the CPU 113 determines whether or not a reproduction command signal coming from the automatic program sending device 14 is input (step ST7a). If the reproduction command signal is input (Yes), the program The corresponding roll data is read out from the data memory 114 and transferred to the output interface 118 (step ST7b), and it is determined whether or not a predetermined time before the stop point of sending the roll data in the read state (step ST7c). The processes in steps ST7b to ST7c are repeatedly executed until a predetermined time before.
[0024]
If the predetermined time before the transmission stop point is reached (Yes), the CPU 113 displays the transmission stop instruction information corresponding to the roll data being read from the instruction information memory 115 and the transmission start instruction information of the roll data to be read next. It is read out and sent to the automatic program sending device 14 (step ST7d).
[0025]
At this time, the CPU 113 monitors the stored contents of the broadcast schedule memory 116, and when the CM data is sandwiched between roll data, the automatic program transmission control device 14 includes the fact that the CM data is transmitted to the transmission stop instruction information. And the next roll data sending start instruction information is sent to the automatic program sending device 14 a predetermined time before the end of the CM data broadcasting time.
[0026]
The CPU 113 also monitors whether or not the time measured by the timer 15 is a predetermined time (about 3 seconds before) the broadcast end time of the program stored in the broadcast schedule memory 116. When the time has passed, TAKE control is performed on the automatic program transmission control device 14 to end the program transmission processing.
[0027]
As described above, in the above-described embodiment, one program server 11 capable of independently recording and reproducing program data is used, and the program data of the program server 11 is recorded by the operator during recording of the program data. A plurality of roll data to be used for broadcasting is extracted from the program data recorded in the memory 114, and these roll data, transmission start instruction information, and transmission stop instruction information are associated with each other and registered in the instruction information memory 115. I am trying to keep it. As a result, during the broadcast time, the CPU 113 reads out the transmission stop instruction information from the instruction information memory 115 and transmits it to the automatic program transmission control device 14 a predetermined time before the transmission stop point of the roll data being broadcast. Then, the transmission start instruction information corresponding to the roll data to be read next is read from the instruction information memory 115 and transmitted to the automatic program transmission control device 14.
[0028]
Therefore, the automatic program transmission control device 14 can grasp the transmission start timing and the transmission stop timing of the roll data based on the transmission stop instruction information and the transmission start instruction information, and based on the grasp result, the reproduction command signal is output. Can be sent arbitrarily. For this reason, the operator of the program server 11 extracts a plurality of roll data from the program data recorded in the program data memory 114, and registers transmission start instruction information and transmission stop instruction information in association with the roll data. The operation of rewinding the recorded tape and the operation of dubbing the roll data to another tape are not required at all by the operation, thereby greatly reducing the operational burden in program editing and broadcasting. In addition, since the time required for program editing is shortened, it is possible to edit programs even immediately before broadcasting, and further, operation mistakes and event change mistakes are prevented, and accurate and reliable program editing and broadcasting are performed. It becomes possible.
[0029]
In the above embodiment, the program server 11 is provided with the broadcast schedule memory 116 storing the information indicating the broadcast start time and the information indicating the broadcast end time of the program data to be broadcast. The time information and the information indicating the broadcast start time and the information indicating the broadcast end time stored in the broadcast schedule memory 116 are respectively compared to determine a predetermined time before the broadcast start time and a predetermined time before the broadcast end time. Based on the determination result, the automatic program transmission control device 14 is subjected to TAKE control for starting broadcasting and TAKE control for ending broadcasting.
Therefore, since the program server 11 determines the broadcast start time and broadcast end time of the program data being recorded, the processing load on the automatic program transmission control device 14 can be kept low.
[0030]
Further, according to the above-described embodiment, the operator of the program server 11 can judge and instruct the broadcast timing of the CM data by itself, thereby allowing the CM data to be arbitrarily broadcast between the main program data. it can. In addition, since the broadcast schedule data of the automatic program transmission control device 14 may be created in untime, there is no need to change the broadcast schedule data from the edited result, and the automatic program transmission control device 14 is thereby operated. For those who do not need to set detailed broadcast schedule data, the labor can be greatly reduced.
[0031]
Furthermore, in the above-described embodiment, when the broadcast schedule data is insufficient as a result of inserting the broadcast time of the roll data, the insufficient feature length can be displayed, and a new roll can be displayed at the lack point. It is also possible to add data.
The present invention is not limited to the above embodiment. For example, in the above embodiment, an example in which CM data is broadcast between roll data has been described. However, the present invention is not limited to this, and emergency bulletins other than CMs, temporary news, and the like may be broadcast.
[0032]
In the above embodiment, TAKE control is performed on the automatic program transmission control device 14 based on the comparison result between the time measured by the timer 15 and the broadcast start time and broadcast end time stored in the broadcast schedule memory 116. An example was described. However, the present invention is not limited to this, and time information measured by an external clock may be acquired.
[0033]
In the above-described embodiment, the example in which the broadcast start time and the broadcast end time are managed by the program server 11 has been described. However, the present invention is not limited to this, and the automatic program transmission control device 14 may manage the broadcast start time and the broadcast end time.
In addition, the configuration of the program transmission system, the configuration of the program server, the type of broadcast program to be handled, the program transmission procedure, and the like can be variously modified and implemented without departing from the gist of the present invention.
[0034]
【The invention's effect】
As described above in detail, according to the present invention, the recorded program data used for broadcasting can be edited quickly and appropriately by one apparatus regardless of the overlap of the recording time of the program and the broadcasting time of the recorded program. Thus, it is possible to provide a broadcast program recording / playback apparatus, a broadcast program transmission method for the broadcast program recording / playback apparatus, and a broadcast program transmission system that can reduce costs and labor on the operator side.
