Multimedia coding-decoder and its method

The disclosed method includes encoding method and decoding method. The encoding method includes following steps: analyzing data sorts, dividing data to text, image, animation, audio, and video; converting data, divided result together with information of time dimension are stored in format of data stream; compressing data stream, EZV lossless compression algorithm is adopted in order to suit features of smaller memory capacity in consuming electronic products since data quantity of digital audio and video information is very huge. The decoding method includes following steps: decompressing data stream, restoring data stream containing information of time dimension; converting data stream into text, image, animation, audio, and video etc. to recover original media information. The codec includes encoder of running the said encoding method, and decoder of running the said decoding method.
