Improve HEVC load-balancing for network streaming using adaptive tile boundary: Anonymous ICME submission
2016
The high quality and low delay video streaming is desired for all users. Especially the playback delay is much more undesirable since it is easily perceived by human eyes, and it consists of decoding delay and transfer delay. In this paper we use High Efficiency Video Coding (HEVC) with tiles to achieve parallel encoding/transmission/decoding, and propose to use a novel adaptive tile boundary (ATB) method to further improve the load-balancing for the whole process. Experiment results show that the proposed method can decrease at most the delay times 22.03% (average 13.83%) and the frame drop rates 41.2% (average 13.92%) under high bit-rates, as well as the delay time 17.04% (average 4.66%) and the frame drop rate 14.3% (average 5.03%) under low bit-rates, comparing with simple parallel processing scheme of using uniform tile partitioning.
