U-FORMAT SP

A Superior Performance version of the H format using a higher video carrier frequency and bandwidth with increased (colour under) chroma bandwidth to improve signal-to-noise ratios. Often includes a Dolby C option for the audio. Many 'SP' recorders automatically distinguish, and give H format performance with older tapes.
