Sorenson MPEG 4 Features

Fully compliant with ISO MPEG-4 simple profile Outstanding video quality codec definition • Automatic scene change detection – when the encoder • Capable of decoding H.263 (short-header MPEG) – senses a scene change, it produces a key frame and allows for backward compatibility and communication allocates more resources (bits) to maximize video quality. between MPEG-4 and H.263. • Support for two-pass VBR compression – produces much higher-quality video by distributing bits in an ideal Exceptional performance fashion. The first pass analyzes the data; the second • Block refresh for packet loss correction – minimizes pass the data for maximum performance errors in the picture, reduces error propagation, and based on the first-pass data profile. eliminates errors due to inequalities in forward and • Compression time packetization for error resiliency to inverse DCT packet loss – minimizes quality degradation due to lost • Media key support through secure encryption – packets by inserting recognizable patterns into the provides very strong protection for content bitstream. If a packet is lost, the decoder automatically • Encoders optimized for G4 and Intel picks up at another point. The decoder doesn’t have to Pentium II/III (optimized for MMX) drop a frame.
