Description of the Related Art In a broadcast program such as a TV (Television), video content data, which is a content material photographed at a site of a data collection destination, is edited and broadcast. The editing of the video content includes editing processing such as rough editing and main editing. The main editing is to produce the final video content data (complete package) which is a completed work from the roughly edited video content data.

In the rough editing, the editor selects a video scene required for the final editing, which is the final process, from the video scenes for each scene composed of the video content data which is the material data immediately after the photographing. , In order to extract the used part of the selected video scene, it is necessary to record the time position (time code) consisting of the edit start position (In point) and the edit end position (Out point) on a paper medium, etc. This is the editing work (coarse editing) before the main editing to extract only the video scenes.

The recording / reproducing apparatus 2 does not necessarily have to be composed of one unit, but is composed of a plurality of units.
Via the network 16, a plurality of editor terminal devices 4 and peer-to-peer (Peer to P)
eer).

By providing a server (not shown) between the recording / reproducing apparatus 2 and the editor terminal apparatus 4, the recording / reproducing apparatus 2 and the editor terminal apparatus 4 are used as clients instead of peer-to-peer. Client / Server (Cl
It is also possible to configure it in the network of the client / server).

The recording / reproducing apparatus 2 is a VTR, and collects video content data recorded in news program coverage, sports patterns such as games, and filming of materials such as movies.
A device for recording or reproducing.

Further, as shown in FIG. 1, by setting (inserting) the recording medium 14 in the recording / reproducing apparatus 2, the video content data is recorded in the recording medium 14 by the recording / reproducing apparatus 2, for example, at the site of news gathering. You can The recording medium 14 according to the present embodiment is a medium such as a magnetic tape, and for example, a digital VTR format video tape used for D10 is wound.

The video content data is data including still image data such as photographs and paintings, moving image data such as movies and plays, audio data such as radio programs, or a combination thereof. The video content data according to the present embodiment uses computer-readable digital data, but analog data can also be used.

Further, 1 video content data includes 1
Alternatively, a video scene composed of two or more frames is configured, and further characteristic frame data composed of one or more frames is included. However, the feature frame data may not be included. A set of one or more video scenes or characteristic frame data constitutes video content data having one narrative.

Further, one video scene or characteristic frame data is composed of one or more image frame data. A collection of frames of image frame data is a video scene that constitutes one scene.

(1.1 Main Editing and Rough Editing of Video Content Data) Characteristic frame data consisting of one or more of the recorded video content data is extracted and converted into extracted characteristic frame data. Based on this, the video scenes (cuts) used in this editing are collected (Logging).

For example, the color bar included in the characteristic frame data is an image or an image signal in which the three primary colors and their catches are shown in strips for use in adjusting the color tone of a television receiver or the like. Characteristic frame data, which is a color bar, is inserted between video scenes as a scene delimiter, and is used for grasping a break between video scenes.

Furthermore, a flash, a chroma flash,
When the feature scene data including fade-in or fade-out is included in the video scene, the feature frame data is extracted, which can be an effective criterion for selecting the video scene required for editing.

For example, when characteristic frame data composed of a flash is included in a video scene, an important person of interest is often interviewed as a subject in a news program broadcast, and when the subject appears, A flash is emitted by a strobe attached to an imaging device for collecting a subject.

Therefore, as the video scene used for editing, the video scene including the flash of the characteristic frame data is often used also in this editing.
By efficiently selecting the video scene in which the flash characteristic frame data is extracted in advance, the efficiency of the editing work can be improved.

Next, the video scenes to be used for editing are selected from the collected video scenes, and the edit start position (In point) or edit end position (Out point) of the video scenes to be used is set. Then, the complete package data for broadcasting (broadcasting) in a program etc. is created after the rough editing, which consists of extracting a video scene for the main editing (main editing).

Conventionally, the complete package data is
The recording medium 14 on which the video content data (recording material data) is recorded is reproduced from the beginning of the video content data, and the editing position, which is the In point or the Out point of the video scene that is considered to be used, is recorded. Based on the time code recorded in, the editing position was manually determined and recorded on a paper medium. The time code will be described later in detail.

However, frame 620 and frame 630
Between frames, the total value (average value) of the luminance component decreases. Therefore, since the total value (average value) of the brightness components increases and decreases within a predetermined time, the characteristic frame data 660 is the characteristic frame data 66 of the flash.
It is determined to be 0.

Of frames 600 to 650, black of frame 600, frame 610, and frame 650 has the lowest total luminance component value, and white of frame 630 has the highest total luminance component value.

Accordingly, the chroma flash characteristic frame data 790 is the frame 710 to the frame 780.
R-Y color difference components (color difference components R-
Y) or BY (color difference component BY), the total value (average value) is calculated for each frame, and if it is larger than a predetermined threshold value, the change in brightness on the blue screen or the red screen is If there is a change in a predetermined number of times, it is determined that the characteristic frame data 790 of the blue chroma flash or the red chroma flash is present. The predetermined threshold can be changed in advance according to the captured video content data.

For example, frame 710 and frame 7
20 indicates that there is a change in brightness (luminance). Subsequently, also in the frame 720 and the frame 730, changes in lightness are shown. After that frame 730
Since the brightness changes a plurality of times between 780 frames, the characteristic frame data 790 is determined to be chroma flash.
