FOUNTAIN CODE BASED VIDEO STREAMING SYSTEM AMD A METHOD THEREOF CAPABLE OF INCREASING THE NETWORK AVAILABILITY THROUGH A FOUNTAIN CODE

摘要

PURPOSE: A fountain code based video streaming system and a method thereof are provided to supply a seamless video streaming service by using a fountain code.;CONSTITUTION: Fountain encoders(400,420) of transmitting devices(40,42) perform fountain encoding of source symbols. A fountain decoder(440) decodes a source symbols by fountain decoding of the fountain-encoded symbol. A pier selector(4440) of a controller(444) selects the peers with reference to a bandwidth of peers. A symbol size determinator(4442) determines the size of a symbol in consideration of a buffer state. The symbol size determinate changes the size of a symbol by recognition of data size of a video decoding buffer(442).;COPYRIGHT KIPO 2013;[Reference numerals] (40) First transmitting device; (400,420) Fountain encoding unit; (42) Second transmitting device; (44) Receiving device; (440) Fountain decoding unit; (442) Video decoding buffer; (444) Controller; (4440) Pier selector; (4442) Symbol size determinator; (AA,BB) Video stream; (CC) Bandwidth; (DD) Buffer state; (EE) Success message
