Problems solved by technology

[0003] However, the encoding and decoding device in the prior art itself is only a chip capable of implementing a single encoding and decoding specification. However, if software is used to process data corresponding to various encoding and decoding technologies, it will cause a serious load on the computer system and affect the performance of the computer system

Embodiment Construction

[0010] Please refer to figure 1 , figure 1 It is a functional block diagram of the integrated encoding and decoding device 10 of the present invention. The integrated codec device 10 is used to convert an input data DATAi into an output data DATAo. In this embodiment, the integrated encoding and decoding device 10 includes a processing unit 20 and a plurality of encoding and decoding modules 22, 24. Please note that without affecting the technical disclosure of the present invention, figure 1 Only two codec modules 22 , 24 are shown in , however, the integrated codec device 10 actually does not limit the number of codec modules provided therein. The processing unit 20 is electrically connected to the encoding and decoding modules 22 , 24 for controlling the operation of the encoding and decoding modules 22 , 24 . The encoding and decoding module 22 is used to convert data corresponding to a first data format into data corresponding to a second data format, and perform corre...

Abstract

This invention provides conformity coding / decoding device for converting an input data into an output data, which contains plurality of coding / decoding module for respectively coding input and output data to generate output and input data, a process unit connected with coding / decoding module for determining activating at least coding / decoding module to convert said input data into output data according to source data and output data format.

Description

technical field [0001] The present invention provides an integrated encoding and decoding device and its method, especially an integrated encoding and decoding device and its method for activating the encoding and decoding module according to the source data format of the input data or the target data format of the output data. Background technique [0002] With the continuous development of multimedia technology, many related applications have also been produced to meet different needs of users. Among them, the animation compression standard formulated by the Motion Picture Experts Group (MPEG) of the International Standards Organization (ISO) provides a standard data interface for devices with different specifications. For example, various manufacturers can individually produce their own encoders and decoders, as long as they conform to the same bitstream data format. And codec devices (coder / decoder, CODEC) of different specifications also provide appropriate compression...
