Why MPEG4 SP?
MPEG 4 SP (studio profile) is a state of the art algorithm that is universally accepted, and provides visually loss-less recording of full bandwidth images. Using both intra-frame and intra-field compression for progressive and interlace recording, respectively, MPEG 4 SP employs both DCT and DPCM (differential pulse code modulation) compression to ensure the best compression application for each type of recording.
