摘要
由于其卓越的效率和性能，许多当今的全球组织和联盟认可并接受了新的和不断开发的H.264/ a VC压缩方法，该方法专为广泛的视频应用而设计。本文介绍了H.264/AVC在带宽有限的移动通信系统中的优势。由于非常有效的压缩方法，H.264/AVC能够以低数据速率传输高质量的视频。为了证明这些能力，我们将H.264/AVC编码技术与目前在移动系统中使用的MPEG-4 ASP(高级简单配置文件)编码技术进行了比较。采用峰值信噪比(PSNR)、视频质量度量(VQM)和结构相似度(SSIM)客观质量测量方法对编码视频测试序列进行质量测量和评价。结果表明并证实了H.264/A VC编码技术的巨大效率和性能可能性，将使其成为多媒体世界的通用编码技术。
Comparison of H.264/AVC and MPEG-4 ASP coding techniques designed for mobile applications using objective quality assessment methods
Due to its exceptional efficiency and performance a number of today's global organizations and alliances recognized and embraced new and constantly developed H.264/A VC compression method designed for a broad range of video applications. This article describes advantages of H.264/AVC in mobile communication systems with limited bandwidth. Due to very efficient compression method H.264/AVC enables and provides transport of high quality video on low data rates. In order to demonstrate these abilities we made a comparison of H.264/AVC coding technique with MPEG-4 ASP (advanced simple profile) coding technique currently used in mobile systems. Quality measurement and assessment of encoded video test sequences was performed with peak signal to noise ratio (PSNR), video quality metric (VQM) and structural similarity (SSIM) objective quality measurement methods. Results showed and confirmed great efficiency and performance possibilities which will make H.264/A VC ubiquitous coding technique of multimedia world in time to come.
