CHAPTER 12 VOICE AND VIDEO OVER IP

Although scalable video is an interesting concept, it takescomplete end-to-end system design to show the advantageof SVC over single-layer coding techniques. With single-layercoding, techniques like bitstream switching and simulcastingcan be used to achieve video adaptati[r]
