Abstract [en]

To efficiently combat the signal loss of MPEG-2 transmission over unreliable networks, priority encoding transmission, unequal packet loss protection and priority dropping techniques have been studied in many papers. Those studies are based on the qualitative analysis of different importance of signals, without quantitative investigation of signal loss effect on video quality. In this paper, MPEG-2 packet loss effect on video quality is quantitatively investigated, a temporal layered signal model is described and evaluated, a quality measure for reconstructed pictures called macroblock impairment ratio is suggested and defined. The investigation and the model are specified for MPEG-2, but the principles and the methods are suitable for any layered video. These are useful for the development of efficient schemes and protocols for packet video transmission over unreliable networks.

Abstract [en]

In this paper we present a novel idea regarding transmission of next generation IPTV content. TodayIPTV systems utilize a COP structure tu provide streamsynchronization points for the clients, these are used whena channel switch occur. Since channel switches made byTV audiences are quite rare it is redundant to send synchronization opportunities in a GOP manner. The proposed design, synchronization frames fur channelswitching (SFCS), only requests synchronization frames when needed. We present a network traffic analysis modeland compare it with simulations. SFCS increases bandwidth utilization compared to traditional COP systemunder the presented transmission environment.
