In this paper, a comparison of a scalable multiple description coding (MDC) scheme and the forward error correction (FEC) coding using Raptor code for the scalable extension of H.264/AVC (SVC) is presented. Unequal and equal protection of the base and enhancement layer with different amount of redundancy at the average burst lengths of 2, 5 and 20 are considered. The experimental results show that...
In this paper, a scalable multiple description video coding method based on the scalable video extension of H.264/AVC (SVC) is presented. The proposed scheme employs a standard SVC encoder to generate several bit streams which have different bit rates. The spatial enhancement layers of these bit streams are quantized in an unbalanced fashion, while the spatial base layers are coded with the same quantization...
Scalable video coding and multiple description video coding are two effective approaches to deal with the problems posed by video streaming over error-prone packet switched networks. In this paper, a multiple description scalable video coder based on the scalable video extension of H.264/AVC is presented. The proposed method downsamples the residual data of the spatial base layer to generate two descriptions...
Digital video (DV) is one of the most popular high quality video formats. Some applications benefit from real-time DV streaming. However, the huge data rate of this digital video format brings some challenges to deliver a digital video stream over the Internet or intranet. In this paper, a variable bit rate DV streaming system with TCP-friendly rate control is implemented. In order to reduce the sending...
