CAST Adds H.264 Main Profile Video Encoder Core to Compression IP Family

WOODCLIFF LAKE, N.J. Jan. 26, 2011

The new core complements the Baseline Profile encoder CAST already offers by delivering better video compression with only a small increase in chip size. Both encoders are sourced from technology partner Alma Technologies S.A, and are distinguished by three factors:

Extremely high quality video output

Easier system integration and application support

Economical, efficient performance

Motion estimation, for example, significantly impacts video quality, and the cores use the most powerful search algorithm (Full Search) as well as all the coding tools the H.264 standard makes available (Variable Block Size, with 1/4 pixel accuracy).

The superior video quality is largely a result of two features: an especially efficient mode selection algorithm, and an advanced rate control implementation based on run-time adaptive content complexity and rate-distortion models. Excellent adaptability to temporal and spatial content variations – enabled by quantization adjustments performed on a sub-frame basis – as well as respect to the decoder’s decoding buffer (HRD compliance) achieve a level of live streaming quality rarely met in hardware encoders. Frame sizes from QCIF to 4Kx4K pixels and compliance up to level 5.1 for both CABAC and CAVLC coders further make these excellent choices for applications ranging from severe low-bandwidth situations to those with data transmission requirements as high as 240 Mbps.

The new H264-MP-E Main Profile Encoder core with its greater compression results is available now, as is the smaller H264-BP-E Baseline Profile Encoder core. The cores are available in RTL source for ASICs, or netlists for FPGAs from multiple vendors.
