Definitions for "Video Compression"
Keywords:  compressed, mpeg, ntsc, jpeg, bandwidth
Both these standards use special hardware & software to store video directly on your hard drive. Video compression is done in various ratios. (eg 10:1,5:1) The higher the ratio, the more video can be stored per meg, and conversly the lower the compression the higher the video quality. See CODEC
This technique (often a MPEG format) compresses video into lower bit rates for easier Internet transmission, often along narrower bandwidths. Video or audio is compressed to shrink file size, ensuring acceptable transfer speed. Compressed video can sometimes be of a noticeably lower quality, but still clear enough to be useful. AVC is the successor to MPEG as the new video compression standard.
Before a video can be displayed on the Internet, it must be converted into a file format that is compatible with the video server being used. This process is called "video compression" because data is compressed to create as small a file as possible.
