摘要
为满足视频通信、智能化监控等的需求,研究了MPEG-4编码技术的应用特点,设计了基于FPGA的MPEG-4编码器IP。通过分类比较的方法,研究分析了MPEG-4编码技术在不同类型中的应用方案,总结归纳了各类应用的特点,为进一步提高编码器的效率、满足低功耗的要求,在FPGA上设计并实现了MPEG-4编码器。经测试表明:该设计方案编码高效,符合实时视频通信的需求,可广泛应用在移动视频通信、远程无线监控等领域。
In order to satisfy video communication and smart video surveillance, MPEG - 4 encoding technology was researched and a scheme of MPEG - 4 video simple profile encoder IP was implemented based on FPGA. According to use classification and comparison methods, the MPEG- 4 encoding technology was discussed in different kinds of applications specified in their implementations. Conclusions were dropped in the characteristics of different applications. In order to accelerate the efficiency encoded further, MPEG- 4 video encoder was designed and implemented on FPGA. According to testing, the result was hoped.
