• VIDEO CASSETTE RECORDING. OF STANDARD PCM DATA

      Hales, John C.; Boeing Aerospace Company (International Foundation for Telemetering, 1986-10)
      Standard video cassette recorders (VCR’s) are relatively inexpensive, small, and capable of recording large quantities of data for hours. The problem with using VCR’s to record pulse code modulated (PCM) digital data is that glitches are recorded in the serial data stream coincident with the video sync pulses. This problem can be solved by formating the PCM data stream and synchronizing the video sync pulses to the PCM data.
