Motivation and Implementation of a Software SVC Real-Time VGAEncoder for Mobile TV

摘要

An encoding system was implemented purely in software for sending SVC video multicast to mobile devices. The SVCencoder is a multi-layer, multi-threaded parallel-GOP encoder. It is capable of running in real-time with an Intel Xeon 5160 Processor dual-core platform in Scalable Baseline profile (H.264/AVC Baseline QVGA@25fps at 250 kbpsto SVC Scalable Baseline VGA@25fps resolution at 1 Mbps. Real-time video encoding is accomplished with aggressiveSingle Instruction Multiple Data assembly code optimizations and advanced algorithms.
