DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a video recording / playback apparatus according to an embodiment of the present invention includes a remote controller 1, a light receiving section 2, an operation panel 3, an operation management section 4, a tuner section 5, and a key frame. It is composed of a display detection unit 6, a display control unit 7, a tape recording / playback unit 8, and a central control unit 9.

Here, the key frame display detection unit 6 automatically generates a frame image (key frame) effective for listing the contents of a video when a telop appears in a video being recorded or a program starts after a CM ends. To detect. The central control unit 9 is a tape recording / playback unit 8 based on an instruction from the operation management unit 4.
Control (recording / playing / fast-forwarding) and recording of a mark signal indicating the appearance of a key frame.

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

During recording, information is recorded on a recording medium or memory.
Processing for securing an image area (step 31) , starting recording (step 32), detecting a key frame, recording a mark signal on a recording medium at the time when the key frame is detected, and storing the key frame in a memory (Steps 34 to 37) are repeated until there is a recording end command (step 33). When there is a recording end command and there is a list screen creation command, a list screen is created, the recording medium is rewound, and the list screen is the recording medium. Is recorded in the empty area (steps 38 to 41). During playback
(Fig. 2 (2)), fast forward playback is started (step 4
2), the list screen recording place Ken knowledge (step 43,4
4) The list screen is displayed (step 45), and when the user performs a key frame selection operation from the list screen (step 46), a mark signal corresponding to the selected key frame is detected (step 47), At the time of detection, that is, from the beginning of the selected key frame, cueing reproduction is performed at normal speed (step 48).

Reference embodiments of the present invention will be shown below. (1) First method (FIG. 3) When recording (FIG. 3 (1)), when recording is started (step
11) detect the key and frame (steps 13, 1
4) The operation of recording the mark signal indicating the appearance of the key frame on the recording medium at the time when the key frame is detected (step 15) is repeated until the recording end operation is performed (step 12).

During playback (Fig. 3 (2)), fast forward playback is opened.
Start (step 16), detect the mark signal (step 1
7, 18), the display mode is judged (step 19), and the normal speed is reproduced in the skip mode (step 24),
In browsing mode, play normal playback for a while (Step 2
0), the key frames are sequentially browsed and displayed (step 21), and when the user selects a key frame, the marker signal corresponding to the selected key frame is detected, and at the time of detection, that is, from the beginning of the key frame, it is normal. Cue reproduction is performed at a speed (steps 22 to 24).

( 2 ) Second Method (FIG. 4) At the time of recording (FIG. 4 (1)), recording is started (step 5).
1) detect a key frame (steps 53, 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 the telop frame is detected, clipping of the telop image (step 57) is repeated until a recording end operation is performed (step 52).

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

( 3 ) Third Method (FIG. 5) At the time of recording (FIG. 5 (1)), recording is started (step 7).
1) The user sets a domain (category such as sumo relay, song program, news number, etc.) (step 73), detects a key frame (steps 74, 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 the recording end operation is performed (step 72).

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

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

Further, when the processing for detecting that the character information is displayed requires a certain time (for example, 1 or 2 seconds or more), the recording time of the mark signal is deviated from the time when the key frame is detected by a certain time. become. Assuming such a case, the reproduction may be started at a time point that is a predetermined time after the time point when the mark signal is detected.

[0035]

As described above, according to the present invention,
By displaying a list of scenes that are effective when listing the contents of a video, such as the appearance of a telop or the start of a program after the end of a commercial, and the beginning of the desired item, the listability of the recorded video information is improved and This has the effect of making it easier to use.
