There are several MPEG compression standards, each designed for different applications. Some of the well-known MPEG standards include MPEG-1 (used for video CDs), MPEG-2 (used for DVDs and broadcast television), MPEG-4 (used for web streaming and multimedia content), and MPEG-7 (focused on multimedia content description).

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.
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.
Many. Basically, MPEG-1 is a compression system that focuses on storing video in a hard disk, that is to say, an "error-free" environment and only is valid for low resolution images. On the other hand, MPEG-2 not only improves the compression factor, but also enhances the capabilities of the antecessor MPEG-1. MPEG-2 can be used not only to store videos (e.g. a DVD) but also can be used for broadcasting. Today's digital television (terrestrial, cable and satellite) uses the compression and signalling of MPEG-2, adapted as international organizations (ATSC, DVB) reccomend. dmb_1
MPEG-1 (used to compress audio) MPEG-2 (used to compress video) MPEG-4 (used for video transmissions over the internet) sound is saved in a Dolby AC-3 compression, or surround sound, MPEG 2 for video compression and requires a MPEG 2 decoder Windows XP has its own decoder software ---- Software bundled with the drive, Windows internal decoding software, and a MPEG decoder card on earlier DVD drives.
Ipod's "preferred format" is H.264, but it will take standard Mpeg-4. Itunes will convert Mpeg-4 into a format that the Ipod can handle.
The Xvid Codec library uses the MPEG-4 video standard also known as the MPEG-4 Part 2 Advanced Simple Profile. The software Xvid Codec is compatible on Windows and Mac PC's.

It depends on the movie and receiver. The formats are either MPEG-2 or MPEG-4. Our HD receivers are in MPEG-4 and the other receivers are in MPEG-2. Eventually they will all be in MPEG-4.
MP3 is short for "MPEG Audio Layer 3". MPEG, in turn, is short for "Motion Picture Experts Group," the organization that invented the compression algorithm and defined the spec. The number 3 means its the third-generation of the spec. The origin of MP4 is similar, but it's a newer spec, and includes video.
MP4 is often referred to as MPEG-4, MPEG-4 Part 1, MPEG-4 Part 14 or MPEG-4 Part 12. Common extensions for MP4 files are .mp4, .m4a, .m4p, .m4b, .m4r and .m4v.
