Improved DVD player system

Abstract

The invention discloses an improved DVD player system, which includes a laser head, a radio frequency amplification module, a digital signal and digital servo processing module, a DVD digital signal processing module, a decoder, SDRAM, a core microprocessor, a first servo driver, The second servo driver, the operation display circuit, the system control microprocessor, the output circuit, the radio frequency amplifier module, the first servo driver, and the second servo driver are respectively connected with the laser head, the radio frequency amplifier module, the digital signal and digital servo processing module, DVD The digital signal processing module and the decoder are connected in sequence. The present invention improves the anti-jamming performance of the video disc player through the two servo drivers of the first servo driver and the second servo driver, and simultaneously uses the radio frequency amplification module, digital signal and digital servo processing module, DVD digital signal processing module, and decoder for data The sequential processing improves the anti-interference performance of the DVD player.

Description

technical field [0001] The invention relates to a video disc player, in particular to an improved video disc player system. Background technique [0002] Video disc players, also collectively referred to as video disc players, are devices that play the sound of movies on discs. A DVD player is an audio-visual device produced by combining digital video technology, digital audio-frequency laser disc technology and computer technology. It has a wide variety of models, and the types of DVD players are mainly distinguished by the types of DVDs that support playback, generally including VCD, Super VCD, DVD, and EVD. Video disc players generally use 12cm discs, which are similar in appearance, but the content format of the discs is different, resulting in different types of machines used. The horizontal definition of ordinary VCD is generally 240-280 lines; the horizontal definition of super VCD can reach about 350-380 lines; the horizontal definition of DVD can reach more than 5...

AI Technical Summary

Problems solved by technology

The existing DVD player needs to be placed on a flat and solid surface. If it is placed obliquely, it will cause the disc to jam or play poorly, which severely limits the placement of the DVD player.
