Definitions

  • the present invention relates to a method of formatting on a digital bus the control information associated with a digitized video signal as well as a device for implementing this method.
  • byte 138 is occupied by the particular value "FF" and byte 139 by a synchronization byte "XY".
  • the "LBLK" bit is set to 1 in the first "XY” byte and is set to zero in the second "XY” byte. This allows the useful video signal to be separated from the control information without using external signals. This specific configuration also simplifies the electronics used to generate the "BD" signals and
