MPEG-1 AND MPEG-2 Video Standards

چکیده
The development of digital video technology in the 1980s has made it possible to use digital video compression in various kinds of applications. The effort to develop standards for coded representation of moving pictures, audio, and their combination is carried out in the Moving Picture Experts Group (MPEG). MPEG is a group formed under the auspices of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It operates in the framework of the Joint ISO/IEC Technical Committee 1 (JTC 1) on Information Technology, which was formally Working Group 11 (WG11) of Sub-Committee 29 (SC29). The premise is to set the standard for coding moving pictures and the associated audio for digital storage media at about 1.5 Mbit/s so that a movie can be compressed and stored in a CD-ROM (Compact Disc – Read Only Memory). The resultant standard is the international standard for moving picture compression, ISO/IEC 11172 or MPEG-1 (Moving Picture Experts Group Phase 1). MPEG-1 standards consist of 5 parts, including: Systems (11172-1), Video (11172-2), Audio (11172-3), Conformance Testing (11172-4), and Software Simulation (11172-5). In this chapter, we will focus only on the video part.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...

In multimedia system, there are several video coding standards such as MPEG-1/2/4 [1]-[3], H.264/AVC [4], VC-1 [5], they are the source coding technology basis for digital multimedia applications. Despite of the emerging HEVC standard [6], H.264/AVC is the most mature video coding standard [4] [9]. China Audio and Video Coding Standard (AVS) is a new standard targeted for video and audio coding...

In this paper, we make a short foray through coding standards for still images and motion video. We first briefly discuss standards already in use, including: Group 3 and Group 4 for bilevel fax images; JPEG for still color images; and H.261, H.263, MPEG-1, and MPEG-2 for motion video. We then cover newly emerging standards such as JBIG1 and JBIG2 for bilevel fax images, JPEG-2000 for still col...

In 1988, the International Organization for Standardization (ISO) established the Moving Pictures Experts Group (MPEG) with the mission to develop standards for the coded representation of moving pictures and associated audio for digital storage media. The work of the MPEG group led to the development of several ISO standards, including ISO 11172, known as MPEG-1 [1]; ISO 13818, known as MPEG-2...
