Abstract
A standard NTSC television video raster image digitized with a 10 MHz sample clock, results in 333, 375 pixels per frame (one frame = two interleaved fields). To send this amount of digital data, uncompressed, over a KHz bandwidth telephone line at a 2400 BAUD rate using ASCII data format requires over 25 minutes of time. The same uncompressed video image can be transmitted over the same 4 Khz bandwidth channel using video signal signature synthesis in a little more than a minute with virtually no loss of image quality.
