Reverse Standards Conversion

Reverse Standards Conversion or RSC is a process developed by a team led by James Insell at the BBC for the restoration of video recordings which have already been converted between different video standards using early conversion techniques. == Historical justifications for its use == Many programmes produced by the BBC in PAL in the 1960s and 1970s were converted to NTSC for distribution to 525 line markets.
