Reverse Standards Conversion

Traditional standards conversion techniques adopted interpolation as a way to cater for the differences between line resolution and field frequency.

Attempts to convert the NTSC version back to PAL format using traditional conversion processes yielded unsatisfactory results.

Early examples of material processed for commercial re-release using RSC are the Doctor Who stories Inferno (1970) and The Claws of Axos (1971).

The resulting DVD release of The Claws of Axos also contained a short documentary about the Reverse Standards Conversion process, presented by Jack Pizzey.

RSC was also used to restore the "Undertaker Sketch" from Monty Python's Flying Circus, which had been cut from the BBC's PAL master tape for being in (deliberately) bad taste.
