  History of MPEG
MPEG (pronounced M-peg), which stands for Moving Picture Coding Experts Group, is the nickname given to a family of international standards used for coding audio-visual information in a digital compressed format.
MPEG has attracted a large number of researchers from both industry and academia because it has succeeded to respond to the needs for standards coming from industry with the enthusiasm and dedication of MPEG delegates.
MPEG is currently powerful as a standards body because of the technical superiority of its standards and the broad applicability of the standards.

 MPEG System Streams in Best-Effort Networks
MPEG is supported also by the Java Multimedia Framework (JMF)[9], so we anticipate that MPEG will continue to grow in importance for Internet applications (e.g., JMF makes it easy to include MPEG movies in applets or HTML pages).
Since the video server may be too busy to handle the computation required to adapt the MPEG system stream to network conditions, we place the adaptation (filtering of data to meet a given resource bound) on other nodes in the network, as depicted in Figure 1.
The filtering of each level of the MPEG system is handled by a different algorithm, to decouple the frame-dropping mechanisms as much as possible from the module that selects the policy for reduction or increase of the data rate.

 Skyvision Frequently Asked Free to Air MPEG-2 Questions
Most MPEG receivers have a loop-through connection to hook the C or KU-Band LNB to and then loop it back to the main receiver.
This can be done by hooking the output of the MPEG receiver to the antenna input on the main receiver or by hooking it directly to the TV if there is an extra input on the back.
Otherwise you will not get a signal since the MPEG receiver will not be able to receive the signal from the switch.

 TechOnline | Introduction to MPEG-4 Video Compression
The MPEG committee last year approved the MPEG-4 standard, which handles video images as objects that form only part of a rich multimedia experience.
Figure 1:  The basic MPEG compression method utilizes motion compensation to remove temporal redundancy and the discrete cosine transform followed by quantization to remove spatial redundancy in video images.
It uses several refinements of the general MPEG compression scheme that provide additional compression efficiency, including spatial compression at the pixel level as well as in the frequency domain.

 MPEG Extension to AVI File Format   (Site not responding. Last check: 2007-11-07)
Editable MPEG files offer significant compression of video data while preserving an image quality close to the original, and allowing frame accurate editing as well as multiple compression-decompression sequences.
While quite efficient for data storage, the MPEG format is not conducive to video editing since some frames (P and B types) require significant amounts of computation to obtain the decompressed image, and since successive decompression-recompression operations usually affect the image quality.
For editing, Editable MPEG files are decompressed through the Video Codec and the Accelerator and returned to the Authoring System as bitmaps, which can then be manipulated, displayed or mixed with bitmaps originating from other types of AVI files.

 MPEG Streamclip 1.8 - MacUpdate   (Site not responding. Last check: 2007-11-07)
MPEG Streamclip converts QuickTime movies, MPEG-1/2/4 files and transport streams into several formats; for MPEG-2 playback and export, the QuickTime MPEG-2 Playback Component is required.
MPEG Streamclip can play and convert selectable parts of QuickTime movies, MPEG files and transport streams with MPEG/AC3/PCM audio into DV streams or QuickTime, AVI, MPEG-4 movies using any video codec, with optional 2D-FIR professional scaling, motion-adaptive deinterlacing, and other pro options; all in YUV, with audio in perfect sync.
Another gripe is that I used multipass VBR maxed at 760kbps for the medium, yet it averaged less than 500kbps, and judging from the video quality, it would have looked a lot better if MPEG Streamclip had kept the bitrate closer to the peak.
