video programming system (VPS)

The Video Programming System (VPS) simplifies recording of television programs with the VCR. The system works with a special VPS identifier that includes the program, the date and the broadcast time and is reflected by a sequence of digits in the program guides.

On the transmission side, this VPS identifier is sent in encrypted form at the start of recording and during the program in the dark-keyed lines of the blanking interval, and is received and decrypted by the VPS decoder in the VTR. If the set VPS identifier matches the transmitted one, the VTR switches to recording and continues recording as long as it receives the corresponding VPS identifier. Only when the set identifier no longer matches the received one does the video recorder switch off the recording function.
