Overview
The first part of module U provides selection of the various audio and video I/O configurations of the player including DC restoration of the external video input.
The second part of module U re-encodes -(R-Y) and -(B-Y) as a PAL chroma signal, mixes luminance and chroma and re-inserts text from disc if it is present. New syncs are inserted then and the resulting signal output goes as CVBS to SCART and encoded CVBS to the BNC outlet socket.
