ABSTRACT:
A television signal format converter is provided for converting without loss of picture information any high definition television format to or from a given recorder/player format. An interface converts between RGB and luminance/chrominance inputs and between analog and digital inputs. The interface couples any proposed high definition television format to a plurality of pairs of memories. A clock and control circuit controls addressing of the memories for reading and writing so that conversion is performed between any high definition television format and the format required for a given high definition digital video tape recorder or any other comparable recorder.
