Joint Intra and Multiple Description Coding for Packet Loss Resilient Video Transmission (original) (raw)

A review of multiple description coding techniques for error-resilient video delivery

Multimedia Systems, 2013

Multiple Description Coding (MDC) is one of the promising solutions for live video delivery over lossy networks. In this paper, we present a review of MDC techniques based on their application domain and we explain their functionality, with the objective of giving enough insight to designers to decide which MDC scheme is best suited for their specific application based on requirements such as standard compatibility, redundancy tunability, complexity, and extendibility to n-description coding. The focus is mainly on video sources but image based algorithms applicable to video are considered as well. We also cover the well-known and important problem of drift and solutions to avoid it.

Video over IP using standard-compatible multiple description coding: An IETF proposal

Journal of Zhejiang University SCIENCE A, 2006

Standard-compatible multiple description coding (MDC) and layered coding (LC) are efficient ways to ensure erasure resilient, scalable transmission of encoded multimedia sources via RTP, allowing a gradual degradation of the application quality with increasing packet loss rate and decreasing bandwidth/throughput on the network. In this paper we review the standard-compatible framework proposed to IETF. Alternative techniques such as robust source coding and channel coding techniques (ARQ: automatic repeat request, FEC: forward error correction) are presented; their integration into the proposed framework is also discussed. The performances of MDC and LC either coupled with channel coding or not, are summarized by reference to current literature. Typical cases and examples are illustrated.

Optimal Bit Allocation in Scalable Multiple Description Video Coding for Packet Loss Resilience

2005

Scalable multiple description video coders (SMDC) allow for better adaptation of video transmission to varying network conditions with compression efficiency comparable to that of non-scalable MDC coders. Recently, we proposed a new SMDC video coding framework, which offers flexibility in the number of descriptions, redundancy level in each description, and bitrate of each description by post encoding processing only [2]. In this work, we propose a low complexity algorithm to find the best low and high rates for this new framework to strike the optimal trade off between compression efficiency and error resilience at a given packet loss rate. We provide experimental results, by means of network simulations, to compare our method with SMDC using a fixed number of descriptions and fixed redundancy level.

Multiple Description Coding versus Transport Layer FEC for Resilient Video Transmission

International Conference on Digital Telecommunications (ICDT'06), 2006

Video content delivery is a challenging task due to its large bandwidth requirements and its sensitivity to transmission errors. In this context, simultaneously providing scalability and resilience against transmission errors is of paramount importance. Layered video coding coupled with multicast video transmission employing no feedback provides the required scalability features and reduces the network burden. However, it is not easy to provide reliability in such environments. This is crucial to mobile users as error rates on wireless links can be high. To compensate for transmission errors, redundancy must be added to the video content. This can be added at the application layer by the employed video coding system, or can be added transparently by the transport layer.
