Core Technologies
MPEGPerfectionTM
technology redefines low-bitrate
compression giving DVD quality
encoding at 1.5Mbps - less than a
third of DVD video bitrates
TurboMPEGTM
technology allows users to convert
formats, resolution and frame rates
of pre-compressed video, at 2X-12X
faster than real-time, to fit video
to any viewing device |
