Abstract

PROBLEM TO BE SOLVED: To obtain a CM transmitter by which coincidence between frame information displayed on a monitor and frame information of an actual CM program frame is confirmed. SOLUTION: When cue-up control between a mother video file 3 and a transmission buffer 5 is finished, a DCU 4 displays frame information superimposingly and starts copying. When the recording of a video signal with frame information superimposed thereon is finished, a remaining front excess length part is recorded. When the recording of the front excess length part is finished, a CPU 2 reproduces CM program resources CM-1, CM-2, CM-3 being main programs sequentially and the CM program is recorded in the transmission buffer 5. When the mother video file 3 finishes the reproduction of the CM program resource CM-3, the CPU 2 controls a stop (still). Thus, the mother video file 3 outputs an image of a final field of the CM program CM-3 as a still image. Since the transmission buffer 5 of a recording side in this case is still in a recording state, the still image is recorded as a post excess length part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CM transmitting apparatus, and more particularly to a CM transmitting apparatus in a commercial television broadcasting station.

[0002]

2. Description of the Related Art It has been a long time since television broadcasting stations (also radio broadcasting stations) are operated by an automatic program controller, which is a kind of computer.

[0003] The television broadcast form of a local private broadcast station is mainly a broadcast program (NET receiving program) transmitted from a key station (station) in Tokyo or Osaka via a network (hereinafter referred to as NET). This is performed by inserting a program (for example, local news) produced by the own station. A quasi-key station is located in a central city (for example, Fukuoka or Sapporo) of one region (for example, Kyushu or Hokkaido), and a NET receiving program received at the quasi-key station is sent to a broadcasting station in another city (NET). Sending) also occurs.

[0004] The revenue sources of commercial broadcasting stations all depend on CM (commercial message) broadcasting fees. Previously,
Large-scale sponsors known all over the country bought up one program and were often broadcasted nationwide at once as one program including a CM program. Thereafter, as the number of sponsors increased and the sponsor fee increased, many programs in which many sponsors piggybacked on one program increased. Naturally, for one program, the sponsors often differ depending on the broadcasting station, and the CM programs are often replaced by the broadcasting stations.

[0005] A CM program is broadcast by connecting, for example, four or eight CM program materials each having a length of 15 seconds.
Broadcasting is performed in units of minutes or two minutes (maximum 9 minutes 59 seconds) of CM program frames. The broadcast time of a CM program frame of a station break between scheduled programs is predetermined in advance.
For the program frame, the broadcast time cannot be determined in advance (such a CM program frame is called an untimed CM program frame).

[0006] Although the broadcast time of the untimed CM program frame is not determined, the broadcasting time of the untimed CM program frame must be known in advance at the local station (NET receiving station) which replaces the CM. As a method for solving this problem, a cue signal is inserted three seconds before the CM program frame in the vertical blanking period of a NET feed (television) program.

For example, a CM program for one or half day is
CMs are recorded in a transmission buffer (optical disk, one video tape, semiconductor memory, or the like) with the frames interposed between the CM program frames, and the transmission buffer is repeatedly played / stopped, so that the CM for one day or half a day is recorded. Transmitting programs is currently performed by almost all Japanese commercial broadcasting stations, and is referred to as CM program unified transmission (broadcasting). This is because the video tape was previously integrated into one.

[0008] In the case of a VTR commonly used in the related art, a start-up time is required from the reproduction start command to the time when the reproduced video signal is stabilized. Usually, the start-up time is 3 seconds.
When one CM program frame is recorded, for example, an extra two seconds is recorded, and a stop tone is recorded in a VTR queue track and stopped. Rewind a little, play the CM program frame just recorded, and stop when a stop tone is detected. The VTR is started from this state, and the next CM program frame is recorded after, for example, 3 seconds (startup time; this corresponds to the timing of switching the CM program frame from the transmission of the cue signal).

However, some video signal (for example, a black (raster whole black) or white (raster whole white) signal, etc.) is recorded in a slightly extra time after the start or end of the CM program frame. . The remaining length after the CM frame and, for example, 3 from the stop tone to the start of the next CM frame.
Seconds of VTR activation time (that is, from the cue signal to the CM
(Until the start of the broadcast of the program frame) is added to the time interval between frames on the CM program unification tape. VTR as sending buffer
Optical disk recorders have become more commonplace,
The shape of program slots has also changed.

FIG. 2 shows an example of one CM program frame when an optical disk recorder is used as a transmission buffer.
That is, several CMs in one CM program frame (three in FIG. 2,
Usually, 4 or 8 CM programs are added before and after the front and back lengths (usually within 1 second).
Let it be M program frames. In the case of a VTR, still playback (playback as a still image by rotating only the drum while the tape is stopped) is possible, but it is not performed by a broadcasting station because the possibility of damaging the tape is high.

On the other hand, in the case of an optical disk, since it is reproduced from the optical disk in a non-contact manner with light, there is no possibility of damaging the recording medium. The start portion of the front margin shown in the enlarged portion 2 is continuously reproduced as a still image. In the case of a commercial television broadcasting station, it is important that the CM program frame is broadcast without errors as described above.

As shown in FIG. 3, in a conventional CM transmitting apparatus, when a transmission buffer 5 is in a standby state and a still image is transmitted, a DCU (display character unit; The frame information (information relating to the next CM program frame to be transmitted) is superimposed and displayed on the monitor 6 by the device 4 for superimposing the characters (characters) and the like on the video screen.

[0013]

The conventional CM shown in FIG.
Since the frame information displayed by the DCU 4 is normally given by the notification from the automatic program controller, the transmitting device matches the frame information of the CM program frame from the transmission buffer 5 to be reproduced (broadcast; OA transmitted) next. Could not be sure that.

An object of the present invention is to provide a CM transmitting apparatus capable of confirming coincidence between frame information displayed on a monitor and frame information of an actual CM program frame.

[0015]

SUMMARY OF THE INVENTION A CM transmitting apparatus for a commercial television broadcasting station according to the present invention is a CM transmitting apparatus including a transmitting buffer means for storing a CM program in units of a CM program frame with a margin added before and after. And a superimposing means for superimposing the frame information of the CM program frame on the front margin when storing in the transmission buffer means.

The operation of the present invention is as follows. When recording a CM program frame in the transmission buffer, the frame information is superimposed on the video signal of the extra margin portion.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a CM transmitting apparatus according to the present invention, and the same parts as those in FIG. 3 are denoted by the same reference numerals.

A CU 4, an I / O interface 1 for interfacing a transmission buffer (file) 5, a CPU 2 for controlling the entire CM transmission device, a mother video file 3 storing all CM programs (materials), a DCU 4, a transmission buffer (file) 5, It comprises a monitor 6.

The operation of the embodiment of the present invention is based on CM program transmission data transmitted from an upper-level computer (EDPS) (data in which CM program materials to be transmitted are arranged in broadcast order. 2), the CM program material is extracted (reproduced) from the mother video file 3 and edited (copied; dubbed) into a transmission buffer (file) 5 in the order of broadcast in units of CM program frames as shown in FIG. Store. At this time, frame information (code) (character information) is superimposed from the CPU 2 via the DCU 4 on the video signal of the remaining length before the CM program frame.

First, the CPU 2 first locates the cue of the CM program material to be reproduced (cue-up; moves the mother video file 3 or the transmission buffer 5 to a reproduction start position or a recording start position of a necessary CM program material or a CM program frame). ), The cue-up control of the mother video file 3 is performed. As a result, the screen of the first field of CM-1 is output. Next, cue-up control of the sending buffer 5 on the recording side is performed, and cue-up of the recording position is performed.

Mother video file 3 and sending buffer 5
Is completed, the frame information to be superimposed and displayed is output to the DCU 4 in order to superimpose the frame information, and the frame information is superimposed and displayed. When the above control is completed, the recording control is performed in the transmission buffer 5, and copying (dubbing; reproducing the reproducing apparatus and recording the output video (audio) signal in the recording apparatus) is started. The DCU 4 is turned off at an appropriate timing to turn off the frame information. When the recording of the video signal on which the frame information is superimposed is completed, the recording of the remaining front margin is performed.

When the recording of the front margin is completed, the CPU 2
Controls the playback of the mother video file 3 on the playback side, and outputs the CM program material CM-1, CM-2, CM
-3 are reproduced in order. As a result, the CM programs CM-1, CM-2, and CM-3 are recorded in the transmission buffer 5.

The CPU 2 determines that the mother video file 3 is C
Stop after playing M-3 program material CM-3 (still)
Perform control. Thus, the mother video file 3 becomes C
The screen of the last field of the M program CM-3 is output as a still image. At this time, since the transmission buffer 5 on the recording side is still in the recording state, this still image is recorded as the remaining length.

Mother video file 3 and transmission buffer 5
Is stopped, recording of one CM program frame is completed. By repeating the above copying operation, a group of CM program frames for one day or half a day required for transmission, for example, can be created in the transmission buffer 5.

When OA (on-air) transmission (broadcasting) of a CM program frame from the transmission buffer 5 is performed, the CM program frame is transmitted by start control from the automatic program controller. First, one CM program frame is transmitted. The leading margin field of the front of the program frame is queued up, and an image recorded in that field, for example, a video signal of the CM program CM-1 is output to the monitor 6.

In this (standby) state, when start control is input from the automatic program control device, the CM program CM-
Reproduction is performed in the order of 1, CM-2, CM-3, and one CM
When the reproduction of the program frame is completed, the front margin of the next CM program frame is queued up. By repeating this operation, CM
OA transmission (broadcasting) of a program is performed.

Therefore, the CM stored in the transmission buffer 5
When the program frame is in standby (state), the stored CM
The still image of the program frame is displayed on the monitor 6 with the frame information superimposed thereon, and the frame information of the CM program frame to be broadcast next can be confirmed.

Each CM stored in the transmission buffer 5
By sequentially reproducing (previewing) the program frames, it is possible to confirm the coincidence between the superimposed frame information and the frame information of the actual CM program frame.

[0030]

As described above, according to the present invention, when the CM program frame stored in the transmission buffer is set to the standby state, the stored still image of the CM program frame is displayed on the monitor 6 with the frame information superimposed. And the frame information of the next CM program frame to be broadcasted can be confirmed.

Each CM stored in the transmission buffer 5
By sequentially reproducing (previewing) the program frames, there is an effect that the coincidence between the superimposed frame information and the frame information of the actual CM program frame can be confirmed.
