Performance Evaluation of H.264 Mapping Strategies over IEEE 802.11e WLAN for Robust Video Streaming

In this paper we propose several mapping schemes for streaming video generated by state–of–the–art H.264 codec over IEEE 802.11e enabled wireless LANs. The schemes take advantage of both 802.11e’s QoS mechanism and some novel features of the H.264 codec, so as to protect the most important information in terms of visual quality and reduce distortion under network congestion. The proposed method...

Comparative Study of Image Compression Algorithms for Transmission over Wireless Networks

In this paper, image compression algorithms have reviewed for transmission over wireless networks. The performance evaluation is based on PNSR, bit-rate, computational complexity etc. and is evaluated using Advanced Image Coding software. It has observed that compression efficiences are reasonably comparable for the JPEG 2000 and AIC, which outperforms the conventional JPEG. Baseline JPEG 2000 ...

An Effective Error-Resilient Coding for H.264 Video

The transmission errors in H.264 may propagate in the temporal direction. Errors in intra-coded picture (I-frame) will propagate into the associated P-B frame if they are in the same Group Of Picture (GOP). Therefore it is important to detect errors in the I-frame rather than in the P-B frame. This paper proposes and demonstrates an effective technique of Error-Resilient Coding based on bit-err...

Error Robustness Evaluation of H.264/MPEG-4 AVC

The robustness of the recently ratified video compression standard H.264/MPEG-4 AVC against channel errors is evaluated with the focus on rate distortion matters. After a brief introduction of the standard and an explanation of its error-resistant features, it is investigated how the error resilience tools of H.264 can be deployed best for packet-wise transmission as in ATM, H.323, and IP-based...

Error-resilient Transmission of H.264/avc Streams Using Flexible Macroblock Ordering

We present a novel scheme for the transmission of H.264/AVC video streams over packet loss networks. The proposed scheme exploits the error resilient features of H.264/AVC codec and employs Reed-Solomon codes to protect effectively the streams. A novel technique for adaptive classification of macroblocks into three slice groups using Flexible Macroblock Ordering is also proposed. The optimal cl...
