Multimedia communications over best-effort networks often involve situations in which immediate data retransmission is either impossible (e.g., network congestion or broadcast applications) or undesirable (e.g., conversational applications with very low delay requirements). A specific solution developed for increasing the transmission reliability without increasing the delay is known as multiple description coding. In this paper, we compare four video MDC schemes based on different time splitting patterns and temporal two- or three-band MCTF. Taking into account the temporal distance between frames, we show the respective advantages and drawbacks of these schemes, for central and side decoders.
