1. Apparatus for interfacing a wide-band tape recorder having M channels in parallel with a digital image processing system, processing frames of digital information made up of arrays of pixels, each pixel represented by an N bit digital word with the digital words representative of the pixels available on an N bit parallel bus in which each line of the array is presented in serial order from top to the bottom of the frame comprising: (a) a memory for storing desired header information which is to be provided with each frame of information; (b) means to buffer incoming N bit words from the bus; (c) means for converting said N bit words into M bit words, said means for converting having said N bit words from said means to buffer as inputs and providing an M bit parallel output; and (d) output means having as inputs the M bit parallel output of said means for converting, and having an M bit parallel output coupled as the input to said wide-band tape recorder, said output means adapted to insert the header information contained in said memory at the beginning of each frame of information which is transferred to said tape recorder.
