This paper discusses two new frame types, SP-frames and SI-frames, defined in the emerging video coding standard, known as ITU-T Rec. H.264 or ISO/IEC MPEG-4/Part 10-AVC. The main feature of SP-frames is that identical SP-frames can be reconstructed even when different reference frames are used for their prediction. This property allows them to replace(More)
We propose a model-based analytic approach for evaluating the overall efficacy of FEC coding combined with interleaving in combating packet losses in IP networks. In particular, by modeling the network path in terms of a single bottleneck node, described as a <i>G</i>/<i>M</i>/1/<i>K</i> queue, we develop a recursive procedure for the exact evaluation of(More)
In this paper, we extend our work in [1] and address an approach to theoretically analyze the rate-distortion (R-D) performance of the weighted prediction feature provided within the scope of H.264/AVC. We consider the weighted prediction as a standard-compatible leaky prediction approach for the purpose of error resilience. We adopt a quantization noise(More)
This paper addresses introduction of special video effects to the coded bitstreams in compressed domain. We propose novel compressed domain operations to achieve several video editing effects for motion-compensated family of video codecs. We then present detailed description of achieving blending of two video sequences. Results demonstrate significant(More)
