This paper investigates the algorithmic complexity of arithmetic coding in the new H264 video coding standard and proposes a coprocessor to reduce it by more than an order of magnitude. The coprocessor is based on an innovative algorithm known as the MZ-coder and maintains the original coding efficiency with a multiplication-free, non-stalling, fully pipelined architecture with modest hardware ...

This memo describes an RTP payload format for Scalable Video Coding (SVC) as defined in Annex G of ITU-T Recommendation H.264, which is technically identical to Amendment 3 of ISO/IEC International Standard 14496-10. The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload, as well as fragmentation of a NAL unit in multiple ...

With the introduction of diverse variety of display transmission and resolutions channel capacities, the Joint Video Team (JVT) has developed the H.264/SVC as an extension of H.264/AVC. In fact, it provides a single compressed bit-stream with several scalability levels. Such a dataflow needs to be analyzed. Consequently, this paper is the first that decorticates and investigates the H264/SVC bi...

The variable block sizes in H264/AVC improve coding efficiency at the price of worsening encoding complexity. To lighten the encoder’s load, a novel fast interframe mode decision Scheme is proposed according to the statistical proportion of each encoding mode. Firstly, check whether the current macro-block is at the skip mode in terms of its characteristics. If so, some encoding modes will be a...

The present work shows a system for compressing and streaming of live videos over networks with low bandwidths (radio mobile networks), with the objective to design an effective solution for mobile video access. We present a mobile ready-to-use streaming system, that encodes video using h264 codec (offering good quality and frame rate at very low bit-rates) and streams it over the network using...

Ultrahigh definition video streaming has been explored in recent years. Most recently the possibility of 4kUHD video streaming over wireless 802.11n was presented, using preencoded video. Live encoding for streaming using x264 has proven to be very slow. The use of parallel encoding has been explored to speed up the process using CUDA. However there hasnot been a parallel implementation for vid...
