| In recent years there is a notice- able trend to implement the video transmis- sion systems based on shared IP networks. At the same time new generations of video codecs such as H.264 are used in industrial installa- tions. This situation forces the need for con- sideration of methods for efficient video trans- mission in industrial networks such as surveil- lance, identification and control systems. The first part of the article discusses the features of modern video codecs, relevant to the stream- ing applications. Attention is focused on the extensions of the H.264 standard that increase the error-resilience, particularly Data Partition- ing (DP) and Flexible Macroblock Ordering (FMO). Next, the principles of prioritization of the video traffic based on the DiffServ archi- tecture is discussed. In this context, separated section presents in detail the rules for packets marking which enable appropriate forwarding the video data. This information is referenced to current recommendations and technical stan- dards. Next the performance of several classical packet marking algorithms and their possible modifications using FMO- and DP-based error- resilience configurations of H.264 are verified in simulations. |
