Abstract

This invention relates to a digital image decoding device and its method. Said device includes an inverse distribution unit for decoding data fields orderly, in which, the digit image is a compressed image datum including multiple fields with multiple compressed jumbogroup fields, each one includes above mentioned data fields. The inverse distribution unit includes multiple first target value storage zones for storing a first target value of a related un-decoded data field for every compressed jumbogroup field and a second target value storage zone for storing a second target value crossing the compressed jumbogroup data fields.

Description

technical field [0001] The present invention relates to a digital image decoding device and its method, in particular to a digital image decoding device and its method using reverse configuration program. Background technique [0002] As people's market demand for multimedia quality and functionality of entertainment and consumer electronics products increases, the multimedia technology advances towards faster computing speed and more efficient development. Because multimedia applications process video and audio signals in real time (signals are signals, hereinafter referred to as signals), it requires the cooperation of relevant hardware and software resources, and manufacturers continue to try to develop in order to cater to the rapid changes in multimedia technology and the increasingly diverse preferences of consumers. Low-cost, broad marketability, and high-quality multimedia products have become a flexible R&D strategy for manufacturers to adapt to standards and consum...
