SMPTE RP 84 – Reference Carrier Frequencies and Preemphasis Characteristics for 1-in Type B Helical-Scan Television Analog Recording
This practice specifies the video reference frequencies to which the carrier is deviated and the associated video preemphasis for 1-in type B helical-scan television tape recording. (The video deemphasis to be used in reproduction is specified indirectly by requiring a flat input-to-output video response along with a specified preemphasis in recording.)
