The video coding format MPEG is used through the web for video compression. MPEG goes up to MPEG- Part4 that is shortened to MP4.
The compression used will depend on what you want to do with the video. MPEG-2 is used for burning to DVD's. MPEG-4/H264 can be used for streaming from a website. The length of the video and available bandwidth are also considerations when selecting a suitable compression format.
The H.264 video codec is one of the most common formats used today for the recording, compression, distribution, of high definition video. Most video on the Internet as well as HDTV broadcast video is distributed in this format.
The short answer: 3pg is the format used to send audio/video data over 3G networks. The benefit is that 3g phones handle this format.

1. JPEG stands for joint photographic expert group and MPEG stands for motion picture expert group. 2. JPEG is used for picture compression and MPEG is used for video compression. 3. JPEG typically achieves 10:1 compression with little perceptible loss in image quality, whereas compression ratio in MPEG is 30:1 for general video using H.263 and 50:1 for general video using H.264/MPEG4. 4. JPEG and MPEG both uses lossy compression.
Well it's the standard for lossy compression of Audio and Video. It is used to compress VHS video/CD audio down to 1.5Mbit/s without excessive quality loss. The best-known part of the MPEG-1 standard is probably MP3. A very common lossy compression format in the modern world.

.avi is a container format; the file extension itself provides no indication whatsoever of what codec is being used by the audio and video inside it. Because there are many variables, including codec, bit rate, the number of pictures used in the compression algorithm, the sampling size of the audio, etc..., it is impossible to predict with any real accuracy how long a video of an arbitrary file size is.
Compression methods are used for images compression and most common compressions are JPEG which is lossy (you can lost some details or quality of image), LZW which is lossless, RLE and ZIP also lossless compressions.
Both AVI and WMV file formats use specific methods to store and arrange data within the file. They are both able to use compressed files as well as handling non compressed files. The type of file format used offers no indication of the compression ratios used for either the audio or video content of the file.
BGR24 is raw video format used to store uncompressed video by high end camcorders
