Is detected, and cueing reproduction is performed at a normal speed from the head of the key frame.

According to a fourth aspect of the present invention, there is provided a video recording / reproducing apparatus for allowing a user to set a domain which is a category of a video, and listing contents of the video in the video being recorded according to the domain. Means for detecting key frames, which are valid frame images, means for recording a mark signal indicating the appearance of those key frames on a recording medium when the key frames are detected, and Means for detecting a mark signal, means for stopping fast-forwarding at the time the mark signal is detected, temporarily performing normal reproduction, means for sequentially browsing and displaying key frames as still images during normal reproduction, and browsing display. A means for the user to select a specific key frame from a plurality of key frames, and a mark signal corresponding to the selected key frame are recorded. Detecting the time point comprises means for performing cue playback from the beginning of the key frame at normal speed.

According to a fourth aspect of the present invention, there is provided a recording medium on which a video recording / reproducing program is recorded, wherein a procedure for a user to set a main category which is a video category, and a video in a video being recorded according to the domain The procedure for detecting key frames, which are valid frame images when listing the contents of, and a mark signal indicating the appearance of those key frames are:
A procedure for recording on a recording medium when the key frame is detected, a procedure for detecting the mark signal during fast-forward playback of video, and a step for stopping fast-forward playback at the time when the mark signal is detected. A procedure for performing playback, a procedure for sequentially browsing and displaying key frames as a still image during the normal playback, a procedure for a user selecting a specific key frame from a plurality of browsed and displayed key frames, and a procedure for selecting a selected key frame. A video recording / reproducing program is recorded which detects a point in time when a mark signal corresponding to a frame is recorded, and causes the computer to execute a procedure for performing cueing reproduction at a normal speed from the head of the key frame.

The present method uses general-purpose key frames (telops, cut points, commercials, etc.). The nature of the key frame differs for each domain (category of sumo relay, news program, etc.) (eg, sumo wrestling, music start, telop display, etc.). Key frames are detected according to the model set for each domain. The user can specify the domain. Alternatively, automatic domain setting using an electronic program guide or the like is also possible.

The object of the present invention is a VTR device, DVD

Next, a video recording / reproducing method according to an embodiment of the present invention will be described with reference to FIGS.

(1) First Method (FIG. 2) During recording (FIG. 2 (1)), when recording is started (step 11), keys and frames are detected (steps 13, 1).
4) The operation of recording a mark signal indicating the appearance of a key frame on a recording medium when the key frame is detected (step 15) is repeated until there is a recording end operation (step 12).

During reproduction (FIG. 2 (2)), fast-forward reproduction is started (step 16), and a mark signal is detected (step 1).
7, 18), the display mode is determined (step 19), and in the skip mode, reproduction is performed at normal speed (step 24).
In the browsing mode, normal normal playback is performed temporarily (step 2
0), the key frames are sequentially browsed and displayed (step 21), and when the user selects a key frame, a landmark signal corresponding to the selected key frame is detected. The cue reproduction is performed at the speed (steps 22 to 24).

(2) Second Method (FIG. 3) During recording, an information recording area is secured in a recording medium or a memory (step 31), recording is started (step 32), a key frame is detected, and the key frame is detected. When a frame is detected, a mark signal is recorded on the recording medium, and the process of storing the key frame in the memory (steps 34 to 37) is repeated until a recording end command is issued (step 33). When the creation command is issued, a list screen is created, the recording medium is rewound, and the list screen is recorded in an empty area of the recording medium (steps 38 to 41). During playback (Fig. 3
(2)), fast-forward playback is started (step 42), the list screen recording location is detected (steps 43 and 44), the list screen is displayed (step 45), and the user performs a key frame selection operation from the list screen. When this is done (step 46), a mark signal corresponding to the selected key frame is detected (step 47), and cueing reproduction is performed at the detected time, that is, from the beginning of the selected key frame at normal speed (step 48). ).

(3) Third Method (FIG. 4) When recording (FIG. 4 (1)), recording is started (step 5).
1) detecting a key frame (steps 53 and 54),
A mark signal in which a key frame appears is recorded on a recording medium when the key frame is detected (step 55),
When a telop frame is detected, clipping of a telop image (step 57) is repeated until a recording end operation is performed (step 52).

The time of reproduction (FIG. 4 (2)) is the same as the time of reproduction of the first method (steps 58 to 66).

(4) Fourth Method (FIG. 5) At the time of recording (FIG. 5 (1)), recording is started (step 7).
1) The user sets a domain (category of sumo relay, song program, news number, etc.) (step 73), detects a key frame (steps 74 and 75), and outputs a mark signal corresponding to the key frame to the key. When the frame is detected, the operation of recording on the recording medium (step 76) is repeated until there is a recording end operation (step 72).

At the time of reproduction (FIG. 5 (2)) is the same as at the time of reproduction of the first method (steps 71 to 85).

The processing shown in FIGS. 2 to 5 is recorded as a video recording / reproducing program on a recording medium such as a CD-ROM, FD, or semiconductor memory, and is read out by a computer so that the tape recording / reproducing unit 8 and the like are read. It can be controlled and executed.

If the process of detecting that the character information is displayed requires a certain period of time (for example, 1 or 2 seconds or more), the recording time of the mark signal is shifted by a certain period from the key frame detection time. become. Assuming such a case, the reproduction may be started from a point in time when the mark signal is detected and a predetermined time earlier.

[0035]

As described above, according to the present invention,
By displaying a list of effective scenes when listing video contents, such as the appearance of a telop or the start of a program after the end of a commercial, and by locating desired items, the listability of recorded video information is enhanced, and This has the effect of making it easy to use.
