Abstract

The invention relates to a disc player and relative playing method, wherein said method comprises that 1, decoding and storing the data of disc into buffer; 2, comparing stored data of buffer with input standard value 1; 3, when data of buffer is higher than standard value 1, reducing the playing speed. The invention can effectively play data and extract data quickly.

Description

technical field [0001] The invention relates to the playing technology of the optical disc drive, in particular to an optical disc playing device and its method which can play the data of the optical disc more stably. Background technique [0002] As a medium for recording digital information, compact disc (Compact Disk; hereinafter referred to as CD) series, or digital versatile disc (Digital Versatile Disk; hereinafter referred to as "DVD") series, etc. Recording / playback devices for recording media are demanding higher recording / playback speeds in order to be able to record / playback a large amount of information such as moving images. [0003] Therefore, recently, the playback speed of an optical disk player is 48 times or 52 times for CDs, but tends to be increased by 16 times for DVDs. [0004] If the playback speed is increased in this way, although the data can be transmitted quickly, the stability of the data may also be reduced. In addition, due to the influence of...
