Super MPEG Encode Pre-Processor for D-VHS Recorders To record analog sources in high-quality digital, the D-VHS recorders use JVC's exclusive Super MPEG Encode Pre-Processor to eliminate the defects inherent in analog signals and create new digital recordings that actually appear to surpass the original quality. The Time Base Corrector (TBC) eliminates jitter, Frame Synchronizer corrects frame crossover jitter and processes any deviant frames, and Motion Active Noise Reduction circuit removes noise from both still and moving parts of video pictures. The decks digitally encode and record the now pristine NTSC-compliant analog input signals, free of image lag, smear and MPEG artifacts such as mosquito noise.
