Mutual Effects Of BTSC Stereo And RF Sync Suppression Scrambling (1987)

By Kenneth D. Leffingwell, Wegener Communications

This paper deals with the interaction of BTSC stereo and RF scrambling systems. Both gated and sine-wave sync suppressed systems are examined. The results of separation measurements at various points in the system using both commercial and consumer stereo decoders are presented. Also presented is a subjective evaluation of both video and audio quality variances due to interaction.
