The order of CMs is set, and the data signal is transmitted to the broadcasting equipment in the subsequent stage in the order.

FIG. 6 is a diagram showing the structure of a conventional CM bank. In FIG. 6, reference numeral 14 denotes a main body of a data processing device, which is a so-called server (video server), which is the center of the CM bank system (hereinafter referred to as a server unit).
Reference numeral 6 is a material tape reproducing VTR for reading out data for reproducing the image and sound (hereinafter referred to as material) of the CM that has been carried in and transmitting it as a master material signal (including a video signal and an audio signal. For example, a composite signal). is there.
A material recording unit 7 performs a control process for recording (registering) material data (hereinafter referred to as material data) in the HDD 8 based on the master material signal transmitted from the material tape reproducing VTR 6. Reference numeral 5 denotes a material registration terminal for transmitting, as a signal, material registration control data such as a material registration instruction, a material code attached to each material, and a material usage period, which is input by a material registrant (operator). . Reference numeral 3 denotes a material registration control unit that controls the material tape reproducing VTR 6 and the material recording unit 7 based on a signal transmitted from the material registration terminal 5. Also, the material registration control unit 3
Also performs processing for causing the material recording unit 7 to register the material registration control data in the HDD 8 in association with the material data. 8
Is an HDD (Hard Disk Drive) serving as a recording unit for recording (registering) the data processed by the material recording unit 7. Further, in the HDD 8, data such as a table showing the relationship between the material registration control data and the material data is also registered.

Reference numeral 9 is a playlist terminal device for transmitting material reproduction control data such as a material code and material reproduction date and time inputted by the operator as a signal. Reference numeral 10 gives an instruction to the preview reproducing section 2 or the material broadcasting reproducing section 11 based on the signal transmitted from the playlist terminal 9 to process, reproduce (transmit) the material data, and control the order thereof. It is a material reproduction control unit. Reference numeral 2 is for instructing the HDD 8 to reproduce the material for the preview, processing the data from the HDD 8, transmitting the material signal composed of the video signal and the audio signal, and displaying it on the preview terminal 4, producing the sound, etc. It is a playback unit.

Is a block showing a procedure for confirming whether or not the material is broadcast in the correct order at the determined date and time.

Next, the operation of the conventional CM bank system will be described with reference to FIGS. 6 and 7. First, a material registrant (operator) to a CM bank inputs a material registration instruction from the material registration terminal 5 into the material registration control unit 3 of the server unit 14. At that time, for example, a material code number attached to the material and material registration control data such as registration of a period of use are also transmitted as a signal. The material registration control unit 3 drives the material tape reproducing VTR 6 based on the input instruction. The material recording unit 7 is instructed to register the material data obtained based on the master material signal in the HDD 8 in association with the material registration control data. As a result, the “material”, “material code”, and “use period” are recorded in the HDD 8 as a file (data file) for each CM (block 54). A file is a unit for storing or processing data.

The operator inputs the material code to be preview-reproduced from the playlist terminal 9 in order to confirm whether or not it is registered in the HDD 8, and the server unit 1
4 inputs a reproduction instruction to the material reproduction control unit 10. The material reproduction control unit 10 operates the preview reproduction unit 2 based on the instruction. The preview reproducing unit 2 reads the material data based on the material code data from the HDD 8,
The material data is processed to reproduce the material on the preview terminal 4. The operator visually confirms, for example, whether the quality of the material and video reproduced on the preview terminal 4 is lower than that of the material before registration and whether the telop is correct (block 55).

The operator also inputs the date and time of broadcasting the material (including the reproduction order of a plurality of materials) as data, and creates CM playlist data at the playlist terminal 9. Then, the material reproduction control unit 10 controls the preview reproduction unit 2 based on the CM playlist data,
Play the material in the order in which it was broadcast. At this time, the material registrant visually confirms whether or not the appropriate CM material is reproduced as scheduled on the date and time to be broadcast, as well as the basic quality of video and audio.

For example, if the supermarket sale starts on February 1, the telops such as "from February 1st" and "2/1 /" will be displayed without error on the CM of the supermarket sale. Check if it has been done. Further, for example, in the case of a CM for accepting concert reservations, it is visually confirmed whether or not a CM for which a telop such as "popularly on sale" is not displayed is selected after the reservation is full (block 56).

In the case of actually broadcasting, the material reproduction control unit 10 controls the material broadcasting reproduction unit 11 to process the material data from the HDD 8 and transmit the material data to the broadcasting transmission facility 12 in the broadcasting order to perform broadcasting.

[0012]

As described above, the CM
For the material registered in the bank, it was necessary to visually check the basic quality of video and audio and the content of the telop.

Here, regarding the basic quality of video and audio, the video (audio) before registration and the video (audio) after registration are compared, and for video, for example, the total sum of luminance is compared for each screen. , It is also possible to automatically confirm (check) based on the difference. However, since the content of the telop may change day by day depending on the broadcast date, it is indispensable to visually confirm it, which hinders the efficiency of work in the CM bank.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a material monitoring apparatus capable of improving work efficiency such as CM material registration in a CM bank.

In FIG. 4, the elements having the same reference numbers as those in FIG. 2 perform the operations corresponding to the above-mentioned explanations of the same figure numbers, and therefore the description thereof will be omitted. Reference numeral 1h is a monitoring text association unit for creating additional monitoring text data based on the input monitoring text data.

For example, for a telop on which a particularly important date is written, "2002" and "2002" are made to correspond to each other, or "." Or "."
Make it correspond to "month" or "day". When the expected result is that “A: registered content” = “B: telop content”, for example, the operator has registered “2002.2.1” as the monitoring text data from the material registration terminal 16. In this case, the monitoring text association unit 1h indicates “2002.2.1”, “February 1, 2002”.
“Day”, “February 1, 2002”, etc. are created as additional monitoring text data and registered in the monitoring text information acquisition unit 1c.
