Description

Record video summary device of disk

The present invention relates to a disc reproducing apparatus for playing a video compact disc (VCD), which summarizes the images recorded on the VCD and displays them on a screen so that the user can easily check the images recorded on the VCD. A recorded video summary device.

In general, a VCD is a sound recording of both a voice signal and a video signal together on a disc. The VCD is robust and the recorded data is not easily damaged, and the recorded data can be clearly reproduced using a laser. It is gradually increasing.

A conventional disc player for playing such a VCD sequentially plays the recorded video and audio from the beginning when a VCD is played, and when the user selects a song to play, the audio and video corresponding to the song are played. Regenerated and output.

Therefore, when the user checks the entire video recorded on the VCD, it has to be checked by playing the VCD from the beginning or by playing the songs recorded on the VCD one by one. There was a problem that took a long time to check.

Therefore, an object of the present invention is to summarize the recorded image of the disc to reproduce the starting portion of the image corresponding to each song for a predetermined time, and to display it on the screen at a time so that the user can easily check the image recorded on the VCD To provide a device.

1 is a circuit diagram showing the configuration of a recorded image summary device of the present invention.

2 is a view showing a state in which a recorded image is displayed on the screen by the recorded image summary apparatus according to the present invention as an example.

In order to achieve the above object, the recorded video summarizing apparatus according to the present invention includes a song in which control means are recorded as TOC (Table Of Contents) reproduced on a VCD when the summarization function is selected, and an image corresponding to the song is recorded. The position is determined, and the pickup unit is controlled according to the determined image recording position to sequentially reproduce the start portion of the image corresponding to each song for a predetermined time.

Then, the image to be reproduced is processed, and the storage / output control means sequentially stores the storage means under the control of the control means, and when the storing of the image corresponding to each song is completed, the user displays it on the screen. Make it simple.

In particular, the present invention divides the screen into a plurality of screens, and displays a video corresponding to each song on each divided section, so that the user can easily check the entire video recorded on the VCD.

Hereinafter, with reference to the accompanying drawings will be described in detail the recording image summary device of the disc of the present invention.

Fig. 1 is a circuit diagram showing the configuration of a recording image summarizing apparatus of a disc of the present invention. Here, reference numeral 10 denotes a microcomputer as a control means. The microcomputer 10 determines whether the summary function is set by the input key signal, and when the summary function is set, the microcomputer 10 controls to reproduce, store and simultaneously output the beginning of each song recorded in the VCD. .

Reference numeral 20 denotes a DSP (Digital Signal Processing) unit which processes and outputs a digital video signal reproduced by a pickup unit (not shown) under the control of the microcomputer 10.

Reference numeral 30 denotes MPEG (Moving Picture Expert) which is a storage / output control means for decoding the image signal output from the DSP unit 20 under the control of the microcomputer 10 and storing and outputting the image signal in the memory 40 as a storage means. Group) decoder.

Reference numeral 50 is an encoder for encoding and outputting video data output from the MPEG decoder 30.

In the disk recorded image summarizing apparatus of the present invention configured as described above, when the user presses a summary key of the keyboard unit (not shown) to confirm the image recorded on the VCD, the microcomputer 10 inputs the key. The signal determines the summary function settings.

When the summary function is set, first, the microcomputer 10 controls the pickup unit to reproduce the TOC recorded on the VCD, and the microcomputer 10 inputs the reproduced TOC to the number of songs and songs recorded on the VCD. The location where the audio and video are recorded is determined.

In this way, when it is determined that the number of songs recorded on the VCD and the position where the voice and video of the songs are recorded, the microcomputer 10 controls the pickup unit to correspond to the first song among the images of the songs recorded on the VCD. The start portion at which the image to be recorded is recorded is reproduced for a predetermined time, for example, about 10 seconds.

The video signal reproduced as described above is input to the DSP unit 20, processed, decoded by the MPEG decoder 30, and stored in the memory 40 under the control of the microcomputer 10.

As described above, when the start portion of the image corresponding to the first song is reproduced and stored in the memory 40, the microcomputer 10 controls the pickup unit again to reproduce the image corresponding to the next song, and the reproduced image is a DSP. Storage in the memory 40 through the unit 20 and the MPEG decoder 30 is repeated.

In this state, when the beginning of the video corresponding to each song recorded on the VCD is reproduced and stored in the memory 40, the microcomputer 10 stops the playback operation of the VCD, and the MPEG decoder ( 30 is controlled to read and output the beginning of the video signal corresponding to each song stored in the memory 30, and the output video is encoded by the encoder 50 and displayed on the screen.

Here, in the present invention, assuming that nine songs are recorded on a VCD, for example, as shown in FIG. 2, one screen is divided into nine, and the image of one song 9 is recorded at each divided position. Split and display

As described above, the present invention reproduces the start portion of each song recorded in the VCD and displays it on one screen, so that the user can easily identify the video recorded in each song as the image displayed on the screen.
