A low-complexity, interlacing-artifact-aware de-interlacing algorithm which can efficiently remove interlacing artifacts from a video sequence before encoding is presented in this paper. The proposed algorithm detects the areas where interlacing artifacts occur and de-interlaces only those detected areas within a frame. It bypasses areas unaffected by artifacts. The proposed de-interlacing algorithm...
With the advances in the Internet and mobile networks, consumers now wish to enjoy their live and on-demand multimedia contents anytime, anywhere and across any device. Scalable Video Coding (SVC) provides a very attractive solution to achieve this goal. However, SVC streams themselves are not stream-able by a streaming server. The SVC streams must be stored in a proper file format to facilitate packet-based...
This paper describes the optimization techniques of implementing the H.264/AVC HD video encoding on the TI TMS320DM648 DSP platform. Real-time encoding and streaming at 25 fps can be achieved for 720p HD video. The advances in capabilities of DM648 over the DM642 are studied and highlighted with performance comparisons. Utilization of these enhancements allows further improvement on the encoding optimization.
This paper describes in detail the various low level optimization techniques for implementing the H.264/AVC video encoding on the TI TMS320DM642 DSP platform. Optimization speedup performance of 5.25 times faster is achieved. A complete AVC encoding and RTSP streaming server system is also developed on the same platform, which is capable of serving live 4CIF video streaming at 25 fps with approximately...
