最后，在综合了以上研究的基础上，实现了H。263视频编译码软件的实验系统。

At last, based on the integration of the upwards research, we realize the H. 263 video encoding and decoding software experiment system.

所实现的编译码器能对BCH(23,12)码进行正确地编码和译码，能纠正小于或等于3位的随机错误。

The encoder can correctly encode and decode the BCH (23, 12) code which can correct less than or equal to 3 bit error.
