Description

How to Play Video CD System

The present invention relates to a playback method in which a video CD (Compact Disc) system is specifically notified to a user in advance of a screen having a sexual scene during playback, so that playback can be determined according to a user's selection.

In general, a video CD system is characterized by a digital recording method and a non-contact reproducing method, which perform non-contact reproduction of a recording bit signal engraved on a disc by light and thereby perform digital signal processing. Therefore, it is well known that an optical disc system has improved performance which is difficult to realize in an analog recording / reproducing system, as well as operability such as random access or program reproduction utilizing non-contact reproduction.

Such a video CD has a capacity enough to contain a movie, and thus is attracting attention as a VCR replacement product. On the other hand, in the case of adult movies, most of the scenes that can be watched with minors, except for a short time of the entire time of the movie.

Nevertheless, it is common to be graded as an adult, a minor spectator, etc., so in the case of an adult, a minor cannot be seen.

In addition, in the case of adult movies, erotic scenes appear while several people watch a movie together, which may cause viewers to be embarrassed.

Accordingly, an object of the present invention is to provide a playback method in which a viewer can cope with a situation by notifying a viewer that a sexual scene will be played soon.

The present invention provides a reproduction method using a video CD system for reproducing a disc in which a sex scene notice bit is recorded in a sector-based data sequence for achieving the above object: A sex scene notice bit while reproducing data recorded on the disc. Searching for; Displaying information corresponding to a sex scene notice when the sex scene notice bit is found; And skipping the sex scene when a skip key signal is provided to the video CD system from the outside after the information corresponding to the sex scene notice is displayed.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

In general, in the case of a video CD, as shown in FIG. 1 (a), it is stored in sector units, and one sector includes a sector sync area A, a header area B, a sub header area C, and a user data area. (D), an EDC (Error Detection Code) area (E), and an ECC (Error Correction Code) area (F).

Of these, the sub header area (C) is composed of a file number, a channel number, a submode, and coding information. Particularly, the coding information related to the present invention includes a type of data in the user data area (D). type) for more information. That is, the coding information makes it possible to know whether the data in the user data area D is data related to audio, video, or program. In the case where the data in the user data area D is video data, the coding information is composed of 8 bits of 0XXXXXXX as shown in FIG. 1 (b), and the lower 3 bits represent picture coding information. The fourth to sixth bits indicate information about the resolution.

For the seventh bit, it can be 0 or 1, and this bit has no special function to date. Therefore, in view of the above, the present invention intends to give a notice of the erotic scene using the seventh bit of the eight bits representing the coding information of the video data.

That is, by setting the seventh bit of the coding information to 1 before the screen for the erotic scene, for example, 4 to 6 seconds before, 4 to 6 seconds after the seventh bit of the coding information is set to 1 during playback. You can foretell that the erotic scene will be played.

FIG. 2 is a block diagram of a video CD system for performing a playback method of the present invention. The disk 100, the spindle driver 110 for controlling the rotation of the disk 100, and the data of the disk 100 are shown in FIG. By the optical pickup unit 120, the tracking servo and the transfer servo of the optical pickup unit 120, and the servo unit 130 and the optical pickup unit 110 that control the driving of the spindle driver 110. Digital signal processor 140 for performing error detection, error correction, and demodulation on the read data, MPEG (Motion Picture Experts Group) decoder 150 for decoding data demodulated by digital signal processor 140, MPEG Decoding and detecting coding information from the video signal processing unit 160, the monitor 170, and the MPEG decoder 150, which modulates video data among analog data decoded by the decoder 150 and processes and outputs a video signal. Whether to display the scene notice The microcomputer 180, the OSD unit 190 to OSD (On Screen Display) the character information related to the sex scene control under the control of the microcomputer 180, the key input unit for providing a certain function key signal to the microcomputer 180 ( 200).

3 is a detailed flowchart showing a preferred embodiment of the reproducing method of the present invention. Referring to FIG.

As described above, the embodiment of the present invention is based on the premise that a notice is displayed for the erotic scene by inserting 1 into the seventh bit of the eight bits representing the coding information of the video data.

First, the optical pickup unit 120 reads and amplifies data contained in the disk 100 and provides the digital signal to the digital signal processor 140. The digital signal processor 140 detects and corrects an error with respect to the read data, demodulates it, and provides the demodulated signal to the MPEG decoder 150.

After decoding the demodulated data, the MPEG decoder 150 provides the video data to the video signal processor 160 and outputs the audio data to the audio signal processor. The video signal processor 160 converts the input video data into analog, processes the video signal, and provides the video signal to the monitor 170 (S1).

The microcomputer 180 detects the data of the sub header area C from the MPEG decoder 150 (S2), and searches whether the sex scene notice bit is stored from the coding information of the sub header area C (S3). . That is, the microcomputer 180 searches for the seventh bit of the eight bits representing the coding information of the video data and determines that the erotic scene will be played after 4 to 6 seconds if the seventh bit of the coding information is 1, for example.

If the seventh bit of the eight bits representing the coding information of the video data is 1, the microcomputer 180 controls the OSD unit 190 to control the text data related to the notification of the sex scene on the monitor 170 (S4). The OSD unit 190 causes the monitor 170 to display text data related to the notification of the erotic scene under the control of the microcomputer 180.

Thus, the viewer will see the erotic scene notice text on the monitor 170, and will be able to recognize that the erotic scene will be played after 4-6 seconds, for example. When the viewer provides the skip key signal for the scene by using the key input unit 200 (S5), the microcomputer 180 controls the servo unit 130 to skip the scene (S6). The servo unit 130 controls the spindle driver 110 and the optical pickup unit 120 so that the scene is skipped and read by the control of the microcomputer 180.

As described above, the present invention provides a notice for the sex scene during the playback of a video CD, thereby more effectively coping with consumer preferences.
