Video Terms
Composite Video
An analog video signal in which the luma and chroma components are combined (by frequency multiplexing), along with sync and burst. Also called CVBS. Most televisions and VCRs have composite video connectors, which are usually colored yellow.
Scalable Coding
Coding a signal into a number of layers
VHS
VHS an analog format capable of delivering 240 lines of video resolution, along with stereo sound that's nearly as good as CD (in dynamic range and frequency response). Blank tapes usually feature either 120 minutes or 160 minutes of recording time at the highest recording speed (6 hours or 8 hours at the slowest speed). VHS and VCR's are slowly being phased out in favor of DVD players and other digital tape media.
720p
720p refers to "720 progressive", a form of high definition digital television that comprises 720 vertical pixels by 1,280 horizontal pixels. Scanning is done by painting a line of pixels before the next one is painted. Because of the sequential scanning, 720p is better able to handle motion and is actually superior to 1080i for that reason.
