摘要 提出了基于多级RS编码和交织器级联的不等差错保护技术。系统能灵活地根据重要性或者信道状况设置不同保护级别,实现视频流数据的不等差错保护传输。由于采用了Galois域专用乘法器,整体系统的面积大为减少,同时支持全高清视频流的信道编码。 A novel scheme of cascading multi-level Reed-Solomon encoder and interleaver is proposed in this paper system can flexibly set up different protection level according to importance, or the channel condition. As a result of Galois field dedicated multiplier, the area of overall system has dropped a lot, and the channel coding of Full-HD stream is supported.
