Motion Estimation (ME) is the most critical and complex part of any video codec system. The different algorithms and their architectures are proposed for ME process. In this paper, we have proposed an efficient architecture for Hexagon Based Search (HexBS) algorithm and implemented on XC4VSX25 Virtex4 FPGA. Simulation results show that the proposed architecture is capable of calculating the Motion...
Mobile TV services are being actively developed for a variety of last hop, broadband wireless technologies. Application layer error control mechanisms such as Broadband Video Streaming seek to reduce packet loss from raw UDP transport. This paper goes further than existing streaming protocols by integrating source-coded error resilience through data-partitioning and intra-refresh macroblocks with...
An efficient error protection scheme is proposed for video delivery over lossy channels. Flexible Macroblock Ordering is used to generate spatial descriptions that are sent over disjoint paths. Additionally, descriptions are partitioned to allow unequal error protection against burst errors. Experimental results show that a significant quality gain can be achieved (up to 3 dB) in the presence of burst...
