Raptor Coding of H.264/AVC Data-Partitioned Video over a WiMAX Channel
نویسندگان
چکیده
This paper demonstrates robust video streaming for IPTV over an IEEE 802.16e (WiMAX). In the proposed method, an H.264/AVC video bit-stream is data partitioned according to source coding priority. Raptor channel coding is adaptively applied to the partitioned data. In the event of outright packet drops, redundant partition bearing packets serve to protect priority data. Further, to guarantee a minimum acceptable level of video quality, additional intra-refresh macro-blocks reduce the effect of temporal error propagation.

Cross-layer mobile WiMAX MAC designs for the H.264/AVC scalable video coding
To effectively provide the QoS of streaming services in mobile WiMAX systems, this paper proposes a cross-layer design between the streaming server and mobile WiMAX base stations. We will show that for each user the implementation of multiple connections with feedback information of the available transmission bandwidth is critical for supporting H.264/AVC-based scalable video coding in which th...
متن کاملLayered H.264 video transmission with hierarchical QAM
In multimedia communication systems, channel bandwidth and probability of error are the two main limitations that affect the quality of service. Therefore, in applications such as video over mobile networks, a video codec should cope with the erroneous situations of the channel as well as the bandwidth limitation. There are several techniques to make a video bitstream robust to the channel erro...
متن کاملError-resilient Transmission of H.264 Svc Streams over Dvb-t/h and Wimax Channels with Multiple Description Coding Techniques
The European STREP Project SUIT involves the development of a multiple description scalable video codec for the transmission of video content over DVB-T/H and WiMAX channels. In this paper, we elaborate on the architectural design choices for such a multiple description transmission system, which utilizes H.264 Scalable Video Coding (SVC). We follow a phased approach focusing on the following u...

Deployment Video on Demand (VoD) over the next generation (WiMAX) has become one of the intense interest subjects in the research these days, and is expected to be the main revenue generators in the near future and the efficiency of video streaming over next generation 4G is the key to enabling this. We are considering video streaming for real time video was coded by different H.264.x codes (H....
متن کاملData Partitioning Technique for Improved Video Prioritization
A compressed video bitstream can be partitioned according to the coding priority of the data, allowing prioritized wireless communication or selective dropping in a congested channel. Known as data partitioning in the H.264/Advanced Video Coding (AVC) codec, this paper introduces a further sub-partition of one of the H.264/AVC codec’s three data-partitions. Results show a 5 dB improvement in Pe...
