An improved video compression standard over MPEG-1 that offers better resolution at the same 30 frames per second (as MPEG-1). Commonly used by cable television operators and direct broadcast satellite providers to offer digital video services because of its efficient use of capacity, improved quality over analog and stereo sound.
ISO's Motion Pictures Expert Group adopted this codec for the compression and playback of full-motion video. All DVD-Videos are compressed using MPEG-2. CD-i discs are compressed using MPEG-1.
The latter one is widely accepted for high definition digital television, as well as multimedia presentation.
was designed for coding interlaced images at transmission rates above 4 million bits per second. MPEG-2 is used for digital TV broadcast and DVD. An MPEG-2 player can handle MPEG-1 data as well. MPEG-1 and -2 define techniques for compressing digital video by factors varying from 25:1 to 50:1. The compression is achieved using five different compression techniques.
Motion Pictures Experts Group a compression scheme for optimizing moving picture
MPEG-2 is the current data compression system widely in use today. It compresses data by locating and retarding redundant or repetitive image signals, thereby freeing up bandwidth or disk space for moving images.
This is a widely used standard for digital encoding of motion pictures. It typically achieves a 50 to 1 compression of data. It achieves this mainly by not retransmitting areas of the screen that have not changed since the previous frame.
Moving Picture Experts Group, Layer 2. MPEG2 offers resolutions of 720x480 and 1280x760 at 60 frames per second with full CD-quality audio. This is sufficient for all the major TV standards, including High Definition TV (HDTV). MPEG-2 is used by DVD-ROMS and can compress a 2-hour video into a few gigabytes. While the decompressing of an MPEG-2 data stream requires only modest computing power, encoding video in MPEG-2 format requires significantly more processing power.

The standard for DVD video. Supports higher data rates than MPEG-1.
MPEG-2 is an extension of the MPEG-1 compression standard designed to meet the requirements of television broadcast studios. MPEG-2 is the broadcast quality video found on DVDs and requires a hardware decoder (e.g., a DVD-ROM player) for playback.
can compress a 2 hour video into a few gigabytes. MPEG-4 is a graphics and video compression algorithm standard that is based on MPEG-1 and MPEG-2 and Apple QuickTime technology.
Moving Picture Experts Group. The second set of flexible compression standards created by this group is called MPEG2. This set of standards takes advantage of the fact that over 95% of digital video is redundant, however some portions are much less redundant. MPEG-2 handles this by using higher bit rates for more complex pictures and lower bit rates for simple pictures. Without MPEG2 only about 4 or 5 minutes (depending on quality) of video would fit on a 4.7GB DVD.
Motion Picture Experts Group , Standard # 2
A widely-used video compression standard. See MPEG.
MPEG is a group which MPEG develops international standards for compression, decompression, processing and coding of moving pictures and audio. MPEG-2 is the most sophisticated set of standards, and is used in DVB.
The video compression standard used for digital television, DVD, and small-dish satellite TV. This adaptive, variable bitrate process is able to allocate more bits for complex scenes involving a lot of motion, while reducing the bits in static scenes. MPEG stands for Moving Picture Experts Group.
A video compression algorithm that is part of the DVD-Video, Digital Broadcast Satellite, and Digital TV (including HDTV) standard. The algorithm is developed by the Motion Pictures Experts Group (MPEG). MPEG-2 effectively compresses the video picture to about 1/40 of its original size. The picture quality from a MPEG-2 encoded source is superior to that of MPEG-1. back to the previous page
Films must be converted to digital files in order to be stored on a DVD. MPEG-2 is the standard compression process for these digital files.
An encoding standard designed as an extension of the MPEG-1 international standard for digital compression of audio and video signals. MPEG-1 was designed to code progressively scanned video at bit rates up to about 1.5 Mbit/s for applications such as CD-i. MPEG-2 is directed at broadcast formats at higher data rates; it provides increased support for efficiently coding interlaced video, supports a wide range of bit rates and provides for multichannel surround sound coding such as PCM, Dolby Digital, DTS and MPEG audio.
Moving Picture Expertsâ€(tm) Group (most widely used standard for broadcast video compression, now over 10 years old)
abbreviation for "Moving Pictures Experts Group"] The second generation of the popular video compression standard, MPEG-2 presents images at resolutions of 720 x 480 and 1280 x 720 (pixels) at frame rates of 60 frames per second and offers CD-quality audio. The quality of MPEG-2 is good enough for NTSC television signals and even HDTV (high-definition television). MPEG compression works by storing only the parts of the images that change from one frame to the next, instead of compressing the entire frame. Using MPEG-2, an entire feature length film only takes up a few gigabytes of storage space.
A video compression scheme created by the Motion Picture Experts Group for delivering digital video for broadcast television and desktop computer environments.
Video and audio standards for digital broadcast-quality television.
As an international standard, MPEG-2 video (DVB) compression is technology that lets you receive more than 250 free to air channels, available exclusively to those using an MPEG-2 receiver. The result? Your neighbor without MEPG-2 won't be enjoying these 250 channels of sports, local networks, music and wild feeds. Many of the wild feed are still available with free-to-air analog receivers. Catch the International feeds and many wild feeds without the expense of paying for a monthly programming package. This world of DX (distant signals) is an enjoyable and rewarding hobby for those who want to catch the very best.

MPEG-2 delivers 30 frames of video playback per second with a variable compression ration as high as 200:1. Broadcast quality video can be achieved with a 30:1 compression ratio. MPEG-2 will also support MPEG-1 playback. MPEG-2 works by removing redundant signal information during compression and reassembles this data during playback through the use of I-frames, B-frames and P-frames. MPEG-2 is utilized for DVD, HDTV and DBS video.

Mpeg-2 is a compression format for digital information that is used by broadcasters and DVD manufacturers to compress the additional picture detail and digital surround sound into the standard 6 MHz bandwidth used by analog televisions. In each image, mpeg-2 compression records just enough detail to keep the image from breaking up, while in subsequent images only the changes are recorded. Mpeg-2 layering allows the information to be compressed at a ratio of 55 to 1.
An extension of the MPEG-1 compression method, MPEG-2 is the encoding standard used for satellite TV and DVDs. MPEG-2 can handle widely varying bit rates, multichannel surround sound, and interlaced video.
MPEG-2 is a standard for "the generic coding of moving pictures and associated audio information http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=31537." It is widely used around the world to specify the format of the digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar disks.
