FINE GRANULAR SCALABILITY FOR VIDEO STREAMING

Wide variation of available bandwidth over the Internet makes real time streaming of video a challenging area in multimedia communication. Though multilayered scalable coding was proposed as a solution, the range of bit-rates covered is limited and is less flexible to adapt to the varying bandwidth at the time of transmission. Fine Granular Scalability (FGS) in MPEG-4 is a highly flexible coding technique capable of delivering video data over a wide range of bit-rates with high coding efficiency. This paper compares the performance of FGS coding against SNR-scalable coding under bandwidth constraints.
