| Chips&Media’s Coda7 Series is an optimally-unified multi-standard H/W video codec IP that performs encoding & decoding standards such as MPEG-4, H.264, H.263 up to HD resolution at 30 frames per second. Under our advanced design technologies, not only requires ultra low-power and ultra low-clock frequency, but also provides decent flexibility in error concealment, error resilient, and multi-resolution/multiplex decoder control. |
