Abstract

PURPOSE:To easily and surely perform CM retrieving operation, by reading unified editing information from a tape on which CMs are unified, and by skipping the unified tape to a desired CM frame position based on the information. CONSTITUTION:CM frame information recorded on the front end of a tape, on which CMs are unified, of a VTR11 and unified editing information containing tape positions where each CM frame is located are read out and stored in a unified editing information storage device 111 of a controlling device 11. The device 11, in response to inputs through an automatic program editing device 12, a keyboard 13, etc., reads out corresponding information from the device 111 and reproduces a desired CM frame by skipping the tape on which CMs are unified. Thus the CM retrieving operation is performed easily and surely without using plural rolls of tapes and plural sets of VTRs.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a CM (commercial message) sending system for television broadcasting, and particularly to a search device for CMs that have been edited into one.

In general, commercials for television broadcasting are so-called commercials in which the necessary commercials are extracted from the mother 7-il videotape and edited into a single videotape in broadcast order, or vIv video tapes in broadcast order, that is, on-air tapes are created. It was processed by a unified editing system.

Figure 1 shows the conventional unification procedure, in which EDPS (Electronic Data Proc.
The order in which commercials will be aired several days later is given to the commercial editing department by the management department of the sending station.
Unification information such as contents is read into the unification controller using Steno ■. Then, the header described below is written in the video track of the on-air tape using Step 2, which precedes the unification work, and the unification work begins in the next step (2).

Figure 2 shows the recording iR turn of the on-air tape created by the unification procedure in Figure 1. In the figure, 1 is a video signal recording section called a ladder, which indicates the start of unification. In normal cases, color bar signals are recorded. Also 2m,
2b... are CM frames that are recorded in one piece in broadcast order. In E7, 3a, 3b, etc., each CM frame 2a receives information about what kind of CM frame is included after it.
.

This is the CM frame code recorded just before 2b, etc.

By the way, in the case of television broadcasting, for example, when the sports broadcast is carried out as scheduled, it is called Program A, and when it is carried out for an extended period of time, it is called Program B. There are also so-called staircase programs, such as J2, which change the 0M transmission format depending on the situation, such as using 1l-i program C when the program is canceled due to rain or the like.

Figure 3 shows the conventional 0M transmission format for such a staircase program, in which the automatic program control device APC edits the on-air control devices OAC, 0AC2, 0AC3, etc. for each situation as described above. Multiple volumes of 70 program A, program B, program C...multiple video tape recorders VTR, VTR, V
Using TR3..., the switcher SW is used to obtain 0M transmission according to each situation.

However, in the 0M transmission mode of such a staircase program, multiple rolls of tape and multiple VTRs must be prepared, and the operator must manually search each time based on the information for each CM frame mentioned above. This has the disadvantage that the search work becomes extremely complicated. That is,
This should be sent out as described above.@ When creating an on-air tape that unifies commercials in the order of broadcast, the on-air tape includes information about each commercial.
This is because only the information for each frame (CM frame codes 3a, 3b, etc.) is recorded.

Therefore, this invention was made in view of the above points, and it is possible to transmit 0M television broadcasts without having to prepare multiple rolls of tape and multiple VTRs and perform complicated search operations as in the past. The object of the present invention is to provide an excellent CM search device that allows easy search.

That is, the CM search device according to the present invention uses CM frame information in the tape to be unified, which is recorded in advance at the beginning of the unified on-air tape, and tape position information where the main part of the CM frame exists. The present invention is characterized in that, when reading unified editing information including a CM frame and searching for each CM frame, a search position is read from the unified editing information and skipping is performed to that position.

An embodiment of the present invention will be described in detail below with reference to the drawings.

That is, as in the unification procedure shown in FIG. is loaded into. And, prior to the unification work, the first video of the on-air tape was recorded in the station and demo.
・U1. At the same time as writing the 7-track information to the audio track, unification editing information (including CM frame information (code) and tape position information where the main part of the CM frame exists) is written to the audio track based on the 7-track information. After writing, proceed to the unification work in step ①.

Figure 5 shows the recording and turn of the on-air tape created by the unification procedure in Figure 3. Figure 5 - 1 is the header, 2*, 2b, etc. are arranged in the order of broadcasting. This is a commercial frame that is recorded as a book, and is 3a.

3b is a CM frame code indicating subsequent CM frame information, which is similar to that in FIG. 2. 7. 4D knee CM recorded all at once at the beginning of the on-air tape that will be made into a book
This is unified editing information that includes frame information and Tezo position information where the #CMC main frame exists.

The on-air tape for sending out commercials created in the manner described above is processed by the video tape recorder VT shown in FIG.
It is loaded into R11 to search for a desired CM frame and send it out.

Here, an automatic program control device 12 called APC and a CRT keypad 13 are connected to the video tape recorder VTR 11 via a control device 11. and,
When a unified editing information reading command is input using the CRT keyboard 13, the control device 11 issues a search and playback command to the video tape recorder VTR 11. As a result, the video tape recorder VTRI J retrieves and reproduces the integrated editing information (4 in Figure 5) recorded at the beginning of the on-air tape that is read.
) is the unified editing information storage section 111 in the control device 1.
is memorized.

In this case, when the program to be broadcast on TV is a general program, a reproduction command is issued to the video recorder VTR 1 via the control device 11 in response to read commands sequentially given from the automatic program control device 12, and thereby It is sufficient to send out the video signal and audio signal of a predetermined commercial that has been played. Also, when it is a staircase program,
First, depending on the broadcasting situation at that time, A, B, etc.
The automatic program control device 12 or 1° CRT key d? selects which program to select. - Input from the code 13 to the control device 1. Then, control device 1
1 is a desired CM that is a search target based on the unified editing information stored in advance in the unified editing information storage unit 111.
Read the frame tape position and record the video tape recorder VTR.
Order 11 to search (skip 7°).

(2) In the state where the search target is skipped to the T-de position (actually 1 go before it), the video cheaple"-1'VT
R17 is set to PB reproduction mode, the search is completed in on-air automatic stop mode, and the on-air standby state is entered. In this state, when an on-air playback command is given from the automatic program control device 12 via the control device 1, the video tape recorder V
After performing TR11, the desired CM is sent out in the PB playback state.

That is, in the general program part, predetermined CMs are sent out sequentially, but in the staircase program part, the desired CM position is controlled in advance according to the conditions input by the V1 automatic program control device M12 or the CRT keyboard 13. The system searches for the unified editing information read by the device and inserts it into the position of the relevant CM frame.

In particular, even in staircase programs, it has become possible to easily search for commercial slots to be broadcast using one roll of on-air tape and one VTR, and it has been made possible to achieve various operational effects. Become.

It goes without saying that the present invention is not limited to the single embodiment described above and illustrated, and that various modifications and applications can be made without departing from the gist of the invention.

Therefore, as detailed above, according to the present invention, the
It is possible to provide an extremely good CM retrieval device that can perform simple retrieval without having to prepare multiple tapes and multiple VTRs and perform complicated retrieval work when transmitting CMs on Vinoyon broadcasting.
