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. As data is stored in the digital video tape recorder, dummy samples are written along with active luminance samples. The dummy samples may indicate, among other things, the type of format being converted.
