Bi-directional television format digital signal converter with improved luminance signal-to-noise ratio |
摘要 |
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. A clock and control circuit controls 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 digital video tape recorder or any other comparable recorder.
