Abstract

This invention relates to a method for picture coding and decoding and its device. Mode of treating data: Provide the data of the picture, arrange the data in order according to the mathematical protocol; transmit the ordered data and repeatedly arrange the order and transmit, until the rebuild picture partly appeared, according to the rebuild picture to select the interested region; to sign the interested region; adjust the arranged order according to the interested region, correspond the data of interested region and data of other regions it has more priority degree, then transmit the above adjusted data. Use of this invention can point out the interested region before the beginning action of coding then can raise the speed and (or) raise the realizable degree of interested region. So this system can make the rebuild digital picture transmitted by communicate circuit (128) more efficiently.

Description

[0001] This case is a divisional application after the international application PCT / US98 / 03811 (its application date is March 20, 1998 and its publication number is WO 99 / 49413) entered the national phase (Chinese patent application number 98813906.5). technical field

[0002] Modern computers and modern computer networks enable the transfer of large amounts of information between computers and between computers and storage devices. When a computer accesses a local storage device such as a local hard drive or a local floppy drive, large amounts of information can be accessed quickly, but when attempting to access data from a remote storage location, such as over a wide area network (WAN) or the Internet , the data transfer speed will be significantly slower. Therefore transferring large files takes a lot of time. In addition, the storage of large files also uses valuable and limited storage space. Photographic images and similar graphic images are generally considered large...
