Abstract

The device comprises CPU control circuit, storage device circuit, time sequence generator, hard disk interface circuit, decryption and data buffer circuit, decoding circuit, output circuit of audio and video signal, control keys / display, hard disk, power source and input interface circuit. Output of hard disk through hard disk interface circuit is coupled to decryption and data buffer circuit. After decrypting data and buffer processing, output data are fed to decoding circuit. Output of the decoding circuit is connected to input ends of output circuit of video / audio signal respectively. Output ends of output circuit of video / audio signal export video / audio signal to external digital projector and acoustic sound reinforcement facility. CPU control circuit is connected to storage device circuit and control keys / display as well as connected to a setting end of decryption parameter of decryption and data buffer, and connected to control end of time sequence generator.

Description

technical field [0001] The present invention relates to a digital cinema playback device, more specifically, the present invention relates to a portable digital cinema playback device. It belongs to the field of electronic equipment. Background technique [0002] Because digital cinema technology can have many advantages and characteristics that traditional film cinema technology cannot have or cannot match, it has generally received great attention from all walks of life in recent years. [0003] Hose et al proposed the US patent "Equipment and method for cueing a theater automation system" ("Apparatus and method for cueing a theater automation system" US Patent Pub.No.US2002 / 0122155A1, Pub.Date: Sep.5, 2002 ) discusses digital cinema systems. The disclosed digital cinema system is based on a computer server architecture system, and a digital cinema playback video server is formed by inserting a decoder. This kind of digital theater playback equipment composed of PC (per...
