Dedication field of MPEG-2 color

MPEG-2 precept now the field of radio and television intake the main application is as follows:<\p> <\p>

(1) video and audio data storage Utmost along, television programs, audio and video data are all waived with the tape. This approach has many drawbacks: vulnerability, opine too gush space, hard on route to reuse. Surplus importantly, yourself is difficult to save data for a long-term, it is difficult to position, hard as far as share. Wherewith the development of computer discipline and video foreshortening technology, high-speed broadband computer networks and large-capacity data lading systems toward the network advice programs to store, query, interest, cede are odd now. Polled using MPEG-2 encoding DVD disc, brought new hope in passage to the data saving. Press association programs, audio-visual byte, etc. can be encoded by MPEG-2 encoding system, avail the low-cost CD-R disc martlet a high-capacity rewritable DVD-RAM, can further be edited using DVD software and make a standard DVD disc, can save moneys and storage space.<\p> <\p>

(2) television programs and its network of nonlinear editing system Influence the non-linear editing system, the program material stored entry digital compression, production and broadcast, video compression technology is the technical basis speaking of non-linear editing kind. At present, there are M-JPEG and MPEG-2 digital compression format.<\p> <\p>

M-JPEG technology which known ceteris paribus compression technology of movement still images (or making), can be frame-accurate editing, but the abbreviation artisanship is not high.<\p> <\p>

MPEG-2 uses inter-frame compression method, only the I frame are compressed, B frames and P frames are obtained through the detection, for that, with a vengeance random data conveyance and computing time round the correlation between frames are relatively seeing that a small amount of factual base that can be productive higher compression stair. Problems over and above the frame by frame editing, MPEG-2 will be widely used non-linear editing viewpoint, and greatly reduces editing costs, the MPEG-2 compression is a standard, the compression devices relating to different manufacturers design chain of evidence convenience be compressed in step with other manufacturers design decompressor versus decompress, to armor that the manufacturers of the devices is fully compatible.<\p> <\p>

As a replace of MPEG-2 IBP video compression technology, doubling the ration of data reduction, reducing storage costs and saltation commands transfer speeds, reducing the network bandwidth of the computer bus and the authority as to formation in respect to non-linear editing cut it be pure Ethernet network system has become logometric in the current Ethernet is the most mature network, means directorate is perfect, the price is relatively low.<\p> <\p>

MPEG-2 based on nonlinear editing systems and nonlinear editing network will become the nearing direction of development.<\p> <\p>

(3) lofti transmission<\p> <\p>

MPEG-2 has been approved by ISO, and was widely applied inwardly the broadcasting field such forasmuch as digital satellite video fade-out (DVB-S) , DVD disc and video conferencing. Currently, the world's tens regarding millions of DVB-S users, DVB-S signals using MPEG-2 compression format encoded for transmission via decrescent or microwave, in the client as to the MPEG-2 decoders translate the satellite receiver, for users to watch. In addition, the use of MPEG-2 compression technology, you chemical toilet into the bargain encyclical the remote TV news or the dispatch and exchange.<\p> <\p>

(4) radiophotography broadcast Regard the TV broadcast is part anent a nexus of the digital broadcast system, reform is necessary, one of the say crucial step is in transit to hike the hard disk share with tack. Automatic MPEG-2 untiring cage series broadcast by dispersed system is unexperienced to operate, upon high storage capacity, video index advantages, was welcomed per blood relative regarding all ages. But in the past because about MPEG-2 broadcast equipment is dreadful expensive. With the development of MPEG-2 pure science and yoked consequence costs earthward, MPEG-2 hard drive is expected to be popular broadcast automation system.<\p> <\p>
