支持立体多视角的四倍高清H．264／AVC解码器实现

摘要

立体多视角视频编解码协议为H．264／AVC的补充，增加了对同时刻不同视角视频复合码流的编码支持，此外也针对超高清分辨率做了相应扩展。为满足补充协议的解码和显示支持，需要将既有全高清解码器的性能提升至少一倍。新的设计实现提出了流水线架构与新的存储规划，以适应对解码器的速度与图像数据更高的要求。其RTL代码已完成了功能验证与仿真，证明该设计改进是有效的。%Multiview Video Coding （MVC） is an amendment to H. 264/AVC video compression standard that enables efficient encoding of sequences captured simultaneously from multiple cameras using a single video stream. To meet the requirement of MVC decoding and display, at least by 100% performance increasing is needed for function normal and robust. Therefore an improved design with pipeline structure and optimized memory planning is proposed for higher decoding speed and quad FullHD video resolution, which is proved to be effective improvement via RTL behavior verification and simulation.
