Embodiment Construction

[0025] In order to achieve the above object, the present invention adopts technical means and other effects, a preferred embodiment is enumerated, and the description is as follows in conjunction with the accompanying drawings.

[0026] Please refer to figure 2 , the present invention has the DVD player 20 of audio-visual playback to comprise an integrated control unit 21, a motor server 22, a motor 23, a read head server 24, a read head 25, a decoder 26 and a storage device 27. The integrated control unit 21 mainly outputs control signals to control the motor 23 and the read head 25 to read the data marks on the optical disc 28, modulate them into digital signals by the decoder 26, store them in the storage device 27, and output them for playback.

[0027] Wherein, the integrated control unit 21 includes a high-performance processor 211 , an MPEG interface 212 and an output interface 213 . When the DVD drive 20 rotates a disc 28 with a motor 23, a light beam is projected f...

Abstract

The invention relates to a DVD player with video playing which uses a motor to rotate a disk and uses the reading head to read the data mark of the disk. It comprises a processor, a MPEG interface and an integer control unit of the output interface; it outputs the control signal, uses the motor follower and the reading head follower to control the motor and the reading head and uses the processor computing function to match to decoder to modulate the data mark as digital signal, it stores the signal in the storage and forms it into decoding video form to directly output it. The integer control unit can integer the processor of the DVD player to form a single control circuit module or a single chip.

Description

technical field [0001] The invention relates to a DVD disc player, in particular to a DVD disc player which integrates functions such as a servo processor, an output interface and an MPEG decompression format to play video and audio. Background technique [0002] The current standard DVD player does not have the function of video and audio playback. Such as figure 1 As shown, the known standard DVD player rotates the disc 1 with the motor 2, and then uses the optical pick-up head 3 to project a light beam onto the disc 1. Record the different reflectivity of the mark to light, the optical reading head 3 detects different luminous flux, and forms a specific digital mark of 0 or 1 through photoelectric energy conversion. After the operation of the decoder 4 and the microprocessor 5, each group of digital marks is modulated It is a digital signal, which is stored in the storage device 6 for output. [0003] In addition, the microprocessor 5 senses the intensity and speed of ...
