This external genlock device from Video Electronics Ltd performs two functions:

  1. The Beeb-Lock unit synchronises the RGB output from a BBC Micro to a composite colour video signal from a camera, studio, videodisk player, etc. and encodes the three separate RGB waveforms in a standard PAL format.
  2. The BL.2K mix/key board allows the PAL encoded output from the Beeb-Lock to be mixed with the input video signal in a variety of way without the use of any other vision mixing equipment. Alternatively a Beeb-Lock system with the BL.2K board can be used as a 'downstream keyer' to add captions and graphics over the output from an existing studio mixer.

Item consists of:

  • VEL Beeb-lock 2K unit with BL.2K mix/key board installed.
  • VEL BPU1 power supply.
  • Genlock interface cable, type two.
  • Application note BL2K.001: Beeb-Lock downstream mix/key extension board type BL2K.
