Abstract

Applying a new algorithm for the Discrete Cosine Transform superior to any published to date, it is shown that an off-the-shelf microprocessor chip, the Am 2901 4-bit bipolar slice, can be employed in a 12-bit configuration to perform TV imagery data compression in real time. The method of compression is the hybrid technique due to Habibi -- DCT along a 32-pixel segment of a TV line and Differential Pulse Code Modulation line to line, thus processing only one eighth of each field at one time. The significance of the new algo-rithm is that it permits an all-digital implementation of a TV data compression system for Remotely Piloted Vehicles and spacecraft using "off-the-shelf" circuitry.
