Design of an Efficient Video Encoder
Yongjie Yang · Tv Engineering · 2004
In this paper, we propose a principle for the design of DCT domain video encoder with fast and efficient memory. It can convert an H.261 video bit stream into a low bit rate MPEG-4 stream with low spatial resolution for wireless video access. Compared to existing approaches, the proposed video encoder can greatly reduce the required memory space, and its computational complexity is much lower. However, experimental results show that the video quality achieved by the proposed method is equivalent to that achieved by existing methods in pixel domain.
