An improved intra and inter prediction for h 264 in wavelet based video codec

Abstract

Multimedia communications plays an emergent role in every day s life of newlinemodern societies. Until recently, and except for broadcast television and radio, voice newlinewas still the sole communication mechanism. However, the diffusion of digital newlineprocessing algorithms and hardware has brought images, music, and video into newlineeveryday life. The availability of open standards (such as JPEG, MPEG-X Audio and newlineVideo, H.26X) has a major impact on this progression, notably due to the easy newlineinteroperability. Such standards have made the creation, and communication of newlinedigital data aimed at our most important senses, sight and hearing, simple, newlineinexpensive and commonplace. newlineH.264/AVC is a recently developed video compression standard jointly newlinedeveloped by ITU-T VCEG and ISO/IEC MPEG standards committees. The standard newlineis becoming more popular as it promises much higher compression than that possible newlinewith earlier standards. The main goals of the H.264/AVC standardization effort have newlinebeen enhanced compression performance and provision of a network-friendly video newlinerepresentation addressing conversational (video telephony) and non-conversational newline(storage, broadcast, or streaming) applications. H.264/AVC has achieved a newlinesignificant improvement in rate-distortion efficiency relative to existing standards. It newlineuses state-of-the-art coding tools and provides enhanced coding efficiency for a wide newlinerange of applications, including Video Telephony, Video Conferencing, TV, Storage newlinesuch as DVD, Hard Disk Based, Especially High-Definition DVD, Streaming Video, newlineDigital Video Authoring, Digital Cinema, and many others. newlineThere are two types of redundancy present in video sequences. They are newlinespatial and temporal redundancy. Spatial redundancies are present within the frames. newlineTemporal redundancies are present between frames newline
