Abstract
Compression of blocks of digital data is optimized by optimally selecting between frame and field format compression on a block-by-block basis. Specifically, a set of pixel data presented in a field format is compressed to provide a field compressed image signal. The set of pixel data is also presented in a frame format to provide a frame compressed image signal. The field and the frame compressed image signals are quantified; and the compressed image signal having the lesser amount of bits is then selected. The selection effectively improves the quality of the transmitted signal and reduces the structural complexity and manufacturing cost of the image signal encoding apparatus.
