Abstract

An application specific integrated circuit (ASIC) allows for the transposition, compression, and decompression of acquired image video data. The transposition process associated with this ASIC provides for the reordering of received vertically scanned segments of acquired image data into horizontal rows and provides for the deleting of overscan and underscan pixel data associated with each of the vertically scanned segments of acquired data. This transposed data is then compressed. Alternatively, the application specific integrated circuit of this invention provides for the decompression of previously compressed data.
