A theoretical analysis of the overall mean squared error (MSE) in hybrid video coding is presented for the case of error prone transmission. The derived model for interframe error propagation includes the e ects of INTRA coding and spatial loop ltering and corresponds to simulation results very accurately. For a given target bit rate, only four parameters are necessary to describe the overall d...

Video compression enables a number of applications by reducing the required bit rate needed to represent a video sequence, however the compressed video is much more susceptible to errors such as bit errors or packet loss. Conventional video compression standards employ an architecture which we refer to as single-state systems since they have a prediction loop with a single state (e.g. the previ...

Resource limitations lead to a number of challenges in all communication systems. This is also the case for video communication over networks based on the Internet Protocol (IP), where limited rates are shared among competing, heterogeneous users. Packet losses, delays and connectivity losses will be experienced to a varying degree depending on network loads, physical properties and mobilityrel...

One of the top tasks for video streaming, video surveillance, video conferencing and video broadcasting is a low-complexity and real-time video coding and transmission over wireless channels. Taking into account high bit error ratios, packet losses and time-varying bandwidth of wireless systems, the scalable video coding (SVC) is more preferable as compression method for wireless video transmis...

In this paper, we present error-resilient Internet video transmission using path diversity and ratedistortion optimized reference picture selection. Under this scheme, the optimal packet dependency is determined adapting to network characteristics and video content, to achieve a better trade-off between coding efficiency and forming independent streams to increase error-resilience. The optimiza...

This paper examines the threat to video streaming from slow and fast fading, traffic congestion, and channel packet drops. The proposed response is a combination of: rateless channel coding, which is adapt...

Digital video coding has traditionally used frame-by-frame synchronous reconstruction. The transport must then be delayjitter-free, forcing the modern integrated service packet network such as the Internet to operate in an inefficient “circuit emulation” mode. This mode results in a jitter-free delay representative of the worst-case network delay, which is problematic for delay-sensitive intera...

† This work was done as part of a visit to USC funded by FSE European Community ABSTRACT In this work we tackle the problem of error propagation that packet losses can cause in commonly used predictive video coding environments. Using Unbalanced Multiple Description Coding (UMDC) to generate redundant source data, we apply the Consistency Sequence Estimation (CSE) algorithm for estimating the l...
