MPEG Video Coding: MPEG-1, 2, 4, and 7

2014
In this chapter, we examine the ideas behind the MPEG standards, starting with MPEG-1, -2, and then MPEG-4, and 7. In MPEG-1 and -2, bidirectional search for motion vectors is introduced. Interlaced video and high-definition TV (HDTV) are supported in MPEG-2.

Mismatch MB Retrieval for MPEG-2 to MPEG-4 Transcoding

2001
MPEG-4 is leading the compression of multimedia application into the fruitful future for it's affluent functions to support universal access and high performance compression[2]. But two excellent standard-compliant streams, MPEG-2 and MPEG-4 video, will be coexisting in different systems for a long time. This paper addresses the problems of transcoding

Java Enabled MPEG-4 Services: The MPEG-J Framework

1999
The MPEG-2 standard has allowed Digital Television to become a reality at reasonable cost. The advent of MPEG-4 will enable content and service providers to deliver to their customers more advanced services with respect to MPEG-2. For these reasons, a scalable and adaptable device opened both to the consolidated past (MPEG-2) and to the incoming future

Adaptation of MPEG-4 BIFS Scenes into MPEG-4 LASeR Scenes in MPEG-21 DIA Framework

2005
Description and adaptation of digital items can be performed in either binary levels or metadata levels, which are the abilities of MPEG-21 Digital Item Adaptation (DIA) tools. BIFS and LASeR are parts of MPEG-4 standard for describing multimedia scenes, which can be written in XML format and then be encoded into binary format for the consumption of ...

A Tutorial on MPEG/Audio Compression

IEEE Multimedia, 1995
This tutorial covers the theory behind MPEG/audio compression. While lossy, the algorithm can often provide "transparent", perceptually lossless compression, even with factors of 6-to-1 or more. It exploits the perceptual properties of the human auditory system. The article also covers the basics of psychoacoustic modeling and the methods the algorithm
