The progress of science and technology demands multimedia applications to be realized on embedded systems as it involves transfer of large amounts of data. Compared with standards such as MPEG-2, MPEG-4 Visual, H.264 can deliver better image quality at the same compressed bit rate or at a lower bit rate.

Robust Video Watermarking of H.264/AVC
IEEE Transactions on Circuits and Systems II: Express Briefs, 2007A robust video watermarking scheme of the state-of-the-art video coding standard H.264/AVC is proposed in this brief. 2-D 8-bit watermarks such as detailed company trademarks or logos can be used as inconvertible watermark for copyright protection. A grayscale watermark pattern is first modified to accommodate the H.264/AVC computational constraints ...

Frame concealment for H.264/AVC decoders
IEEE Transactions on Consumer Electronics, 2005The H.264/AVC offers a high video coding efficiency and is the first standard that provides an explicit support for the transmission of multimedia content over apacked switched network, specifying a Network Abstraction Layer (NAL). If we consider the transmission of a low resolution video sequence over a wireless LAN network or a UMTS link, we can ...

H.264 is the ITU-T's new, nonbackward compatible video compression Recommendation that significantly outperforms all previous video compression standards. It consists of a video coding layer (VCL) which performs all the classic signal processing tasks and generates bit strings containing coded macroblocks, and a network adaptation layer (NAL) which ...

Introduction to h.264 advanced video coding
Asia and South Pacific Conference on Design Automation, 2006., 2006We give a tutorial on video coding principles and standards with emphasis on the latest technology called H.264 or MPEG-4 part 10. We describe a basic method called block-based hybrid coding employed by most video coding standards. We use graphical illustration to show the functionality.

H.264/SVC vs. H.264/AVC video quality comparison under QoE-driven seamless handoff
Signal Processing: Image Communication, 2012This paper studies the impact of mobility management and seamless handover mechanisms on the perceived quality of video streaming applications. A seamless handoff scheme is proposed that incorporates IEEE 802.21 Media Independent Handover framework and a QoE-driven rate adaptation scheme, for both scalable and single layer coding.

H.264/SVC scalability performance analysis
2013 IEEE International Conference on Signal and Image Processing Applications, 2013The H.264/SVC was developed as an extension of H.264/AVC; the latest scalable H.264 codec (SVC) provides combined temporal, quality and spatial scalability. This paper provides theoretical concepts of these different scalability approaches and analysis of their performances when video are transmitted over IEEE 802.11e WLANs.

H.264 Intra Prediction Architecture Optimization
Multimedia and Expo, 2007 IEEE International Conference on, 2007This paper proposes an optimized H.264 intra prediction arithmetic to reduce the time required to complete the intra prediction by saving ninety percent waste time during the process of intra prediction. Firstly, the 16times16 luminance prediction can be decomposed equally into 16 parts and inserted into the same macro-block's 4x4 luminance prediction ...
