摘要:
MD-FEC is considered an efficient way to generate a large number of descriptions. However, typically, MD-FEC introduces significant redundancy across streams. MD-FEC encoded streams (descriptions) are adapted based on feedback. Specifically, the bits sent in each description by a supplying peer are adapted based on the number of available descriptions in its receiving peer. The adaptive delivery eliminates unnecessary bits in the original MD-FEC streams (descriptions), and significantly reduces the consumed uplink bandwidth at supplying peers. The saved bandwidth can be used to accommodate more video sessions or for other applications.
