CodaDx6 (SD/D1) |
Chips&Media's CodaDx6 is an optimally-unified multi-standard video codec
IP that performs H.264 codec, MPEG-4 codec, and H.263 codec up to D1 resolution
at 30 frames per second in the full-duplex mode. Under our advanced design technologies,
CodaDx6 not only requires ultra low-power and ultra low-clock frequency, but
also provides decent flexibility in rate control, motion estimation, error concealment,
error resilient, and multi-resolution/multiplex codec control.
