<p>A television signal format converter is provided for converting without loss of picture information a 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 a source television format to a plurality of pairs of memories (240). A clock and control circuit controls (230) addressing of the memories for reading and writing so that conversion is performed with an improved luminance signal-to-noise ratio between a source television format and the format required for a given high definition video tape recorder (150) or any other comparable recorder.</p> |
