ABSTRACT:
An encoder circuit utilizes a pair of digital memories clocked at a slower write than read rate to compact analog input data, blanking and synchronization pulse intervals, and generate NTSC video. The NTSC formatted data may be stored utilizing conventional NTSC tape or disc recording equipment or may be transmitted, duplicated, monitored or transcribed utilizing readily available NTSC video equipment. A decoder circuit is provided to reprocess the NTSC video formatted data and restore it to its original form by removing the synchronization and blanking intervals and, utilizing a pair of digital memories clocked at a faster write than read rate, re-stretch the data which was compacted in the time dimension by the encoder circuit.
