H.263 video traffic modelling for low bit rate wireless communications

Video traffic exhibits a greater complexity than traditional services such as voice. Therefore, it is necessary to identify the relevant statistical properties, which characterise this type of traffic and provide the tools to properly model them so that networks could be efficiently dimensioned. This work presents on one hand a detailed analysis of the statistical features, which characterise H.263 video traffic streams coded at bit rates suitable for wireless communications. On the other hand, the paper presents and evaluates an on-line video traffic model, which captures the most significant features observed.
