Progressive Scanning - A system of video scanning where lines of a picture are displayed consecutively (unlike interlaced).
Time Scan/Speedwatch - Allows you to skip commercials and previews during playback.
Channel Balancing - A process that equalizes the level of each speaker in a home theatre system. This feature uses a test tone generated from the receiver and is controlled with keys on the component's remote control. Channel balancing must be performed from the primary seating position.
Digital Image - A picture that is in computer language. Because the picture is represented by a series of numbers, it is very easy and improve the image or to alter it.
Macro Focus - Permits the camcorder to move within inches of the subject for extreme close-ups.
Bus - A data pathway used within a computer system to transfer information within the system.
Resolution - The level of resolution directly affects picture quality. The higher the resolution, the more picture detail there is. Many things affect picture quality, including number of bits, pixel count, format, receiver quality, cameras, lenses and lighting used for live or taped programming. Resolution is measured by the number of pixels displayed. One of the high-definition picture formats is composed of 1080 active lines, and each line is composed of 1920 active pixels. Therefore, each frame has over 2 million (1080x1920=2,073,600) color pixels creating the image. By way of contrast, today's typical analog television is roughly equivalent to 480 active lines, with each line holding about 440 pixels. So, each frame has a little over 200,000 color pixels in use creating the image.
