Design of a caching system for SHVC-coded videos
Tz-Heng Hsu, Wei-Ze Hong · 2017
To support mobile devices with different screen resolutions, social video sharing sites need to provide distinctive versions of the videos for mobile users to choose, resulting in the consumption of massive storage space. Scalable Extensions of the High Efficiency Video Coding (SHVC) can reduce about 15-30% storage of distinctive video spatial resolution. Meanwhile, traditional video caching technology is not applicable to multi-layer SHVC video structure. In this paper, we propose a novel SHVC caching system that can reduce the content delivery and start-up delay of video transmissions. The proposed system also supports the transcoding of various video formats for mobile devices that are incapable of decoding SHVC videos.
