Abstract

PURPOSE:To register a program data onto a digital recording medium of its own station at high speed by recording the program data onto a digital recording medium in advance, distributing the medium to other broadcast station, reading the program data from the digital recording medium and registering it onto the digital recording medium of its own station. CONSTITUTION:A program data is recorded in advance onto a digital recording medium and supplied from other broadcast station. The digital program data recorded on the digital recording medium of the other broadcast station is reproduced from a digital recording medium reproducing device 21 by the control of a CPU 11 and a controller 22 and registered on a large capacity memory 16 capable of random access. Then the data is read in the order of the broadcast scheduler of its own station and broadcast after being converted into an analog signal. When an optical disk is used as the digital recording medium, the data is registered on the large capacity memory 15 at high speed. Thus, the program data is registered on the digital recording medium of its own station at high speed.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a program registration device used in broadcasting stations and the like.

2. Description of the Related Art In general, programs are sometimes supplied between broadcasting stations, and in this case, the supplying broadcasting station records a plurality of programs on a recording medium in the order of its own broadcast schedule.
A broadcasting station supplied with this recording medium must rearrange and broadcast the programs on the recording medium in the order of its own broadcast schedule.

Conventionally, between broadcast stations, images and sounds of programs are recorded on analog recording media such as magnetic tapes, and the recording media are distributed to other broadcast stations by mail or the like. Therefore, a broadcasting station supplied with a recording medium from another broadcasting station is equipped with a program registration device (digital audio file) for broadcasting this program according to its own broadcasting schedule.

FIG. 2 shows the configuration of a conventional program registration device.

In Fig. 2, 1 is a central processing unit (CPU) that controls the entire system, 2 and 3 are a display unit (CRT) and a keyboard for displaying and inputting program broadcast schedules, etc., and 4 is a keyboard. , the display unit 2, and the keyboard 3.

5 is a controller that controls writing and reading of a randomly accessible large-capacity memory 6 such as a magnetic disk; 7 is an analog tape for playing back images and sounds of programs of other stations recorded on an analog recording medium; This is a controller that performs write control and read control of the recording/reproducing device 10 via AD converters 8 and 9, respectively.

Next, the operation of the above conventional example will be explained.

In FIG. 2, program data of other broadcasting stations recorded on an analog recording medium is read out from an analog tape recording/reproducing device 10 under the control of a CPU and a controller 7, and is converted into digital data by an AD converter 8. Under the control of the CPUI and controller 5, it is registered in a randomly accessible large-capacity memory 6.

Therefore, the program data recorded in the randomly accessible large capacity memory 6 can be read out in the order of the broadcast schedule under the control of the CPU, and the read digital program data is converted into an analog signal and then broadcast. be done.

Problems to be Solved by the Invention However, in the conventional program registration device described above, the analog tape recording/reproducing device 10 has a maximum playback speed of 4.
The problem is that recording at double speed is the limit, and therefore program data cannot be registered in the large capacity memory 6 at high speed.

Note that when the sampling frequency of program data is 20 KHz and the number of recording bits is 8 bits, the data transfer rate is l 5 Q Kbit/s, and when registering at 4x speed, it is 640 Kbit/S.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a program registration device that can register program data in a digital recording medium of its own station at high speed.

Means for Solving the Problems In order to achieve the above object, the present invention records program data in advance on a digital recording medium and distributes it to other broadcasting stations, reads out the program data from this digital recording medium, and transmits it to the own station. It is designed to be registered on a digital recording medium.

Effects With the above configuration, the present invention can record at a speed of, for example, 6 Mbit/S when an optical disc is used as a digital recording medium. Therefore, compared to the conventional example, program data can be transferred to the own station's digital recording medium at a higher speed. You can register at .

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a program registration device according to the present invention.

In FIG. 1, 11 is a central processing unit (CPU) that controls the entire device, and 12 and 13 are display units (CRTs) for displaying and inputting program broadcast schedules, etc.
), keyboard, 14, display section 12, keyboard 13
This is a controller that controls the input and output of data to and from the computer.

Numeral 15 is a large-capacity memory composed of a randomly accessible medium such as a magnetic disk, and is used to register and reproduce digital data of broadcast programs. Numeral 16 is a large-capacity memory that controls writing and reading of the large-capacity memory 15. It is a controller.

Reference numeral 17 denotes an analog tape recording/reproducing device for reproducing, at low speed, analog data such as images and audio of programs of other broadcasting stations recorded on magnetic tape, etc.; An AD converter 19 converts analog data into digital data; a DA converter 19 converts digital data of a program into an analog signal and writes the analog signal into the analog tape recording/reproducing device 17;
0 is a controller that controls writing and reading of the analog tape recording/reproducing device 17.

21 is a digital recording medium reproducing machine for reproducing at high speed digital data of images and sounds of programs of other broadcasting stations recorded on digital recording media such as optical disks;
2 is a controller that performs read control of the digital recording medium playback device 21;

Next, the operation of the above embodiment will be explained.

First, program data is recorded in advance on a digital recording medium such as an optical disk, and is supplied from another broadcasting station.

In FIG. 1, digital program data of other broadcasting stations recorded on a digital recording medium is played back from a digital recording medium playback device 21 under the control of a CPU 11 and a controller 22. Large-capacity memory 15 that can be randomly accessed by control
will be registered.

Therefore, randomly accessible large capacity memory 15
The program data registered in the station can be read out in the order of the broadcast schedule of the own station, and the read digital program data is converted into an analog signal and then broadcast.

Here, when an optical disk is used as the digital recording medium, it can be read out at a speed of 6 Mbit/s and registered in the large capacity memory 6, which is faster than when read out from the analog tape recording/reproducing device 17 as in the conventional example. can be registered in the large capacity memory 6 at high speed.

According to the above embodiment, if information such as program operation data is written in advance on a digital recording medium and supplied to another broadcasting station, the supplied broadcasting station reads the information and displays it on the display unit 12. By displaying the information, the content of the program can be confirmed in a unified manner.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention records program data in advance on a digital recording medium, distributes it to other broadcasting stations, reads out the program data from this digital recording medium, and registers it in the digital recording medium of the own station. Therefore, when using an optical disk as a digital recording medium, for example, 6M
can be registered at a speed of bit/s, thus
Program data can be registered in the own station's digital recording medium at a higher speed than in the conventional example.
