A system design of H.264 HD encoding Used in broadcast television systems

摘要

This article focuses on design of H.264 video encoding system basing on FPGA and MB86H46 and its application in modern radio and television field. Firstly, we introduces two important interfaces applied in broadcasting and television system: interface SDI and interface ASI, and analyze its key technology. Secondly, design of embodiment of H.264 video decoding system which bases on FPGA and MB86H46 clips are described, major components of this video decoding system are illustrated in detail. Finally, the design of the coding system has been tested and we give the test results and performance analysis.
