Combo Decoder Summary
Video and Audio Technologies Codec Group RealNetworks, Inc October 23, 2002 Version 1.0
Summary
This document a summary of the RealVideo 8 and RealVideo 9 Codec. RealVideo 8 and 9 achieves new levels of compression performance at low as well as high data rates. The improvements are due in part to 1/3 and 1/4 pixel interpolation for motion estimation, the addition of 16x16, 16x8, 8x16 and 8x8 pixel motion compensated blocks, 4x4 pixel block transforms, 16x16 “double” transforms, use of smart in-loop filters, efficient coding of 4x4 intra prediction modes, run length coding of MB-Types, and more efficient variable length coding of residual transform coefficients. RealVideo 9 doesn’t need a post filter, while RealVideo 8 does take advantage of one. RealVideo 9 adds
