Abstract
Many studies have been conducted to evaluate the benefits of using layered video coding schemes as a means to improve the robustness of video communications systems. In this paper, we study a frame-aware nonlinear layering scheme for the transport of a DCT-based video over packet-switched networks. This scheme takes into account the relevance of the different elements of the video sequence composing the encoded video sequence. Throughout a detailed study over a large set of video streams, we show that by properly tuning the encoding parameters, it is feasible to gracefully degrade or even maintain the video quality while reducing the amount of data representing the video sequence. We then provide the major guidelines to properly tune up the encoding parameters allowing us to set the basis towards the development of more robust video communications systems.

We have analyzed the performance of a video encoding scheme able to improve the video quality while reducing the amount of data used to represent the video sequence
Summary
Recent developments in the areas of video coding and compression techniques are enabling the deployment of computer-based video communications systems. Most techniques used for the reliable transfer of video over communications networks can be classified into two classes [2]: error-resilient techniques and regeneration techniques The former are implemented in the codecs as well as in the switching elements of the networks, while the latter are implemented by the decoder by making use of redundancies present in the encoded stream to regenerate the missing pieces of information. Both techniques can be combined to develop structured error-resilient video communications systems [3].
