Hantro 6200 H.264/AVC Encoder
Targeted for implementing 3GPP compliant video applications such as: video recording (MMS) and video telephony. The 6200 encoder is fully optimized for ARM9 and ARM11 SIMD instruction sets, however as a pure ANSI C implementation the code can also be complied and further optimized for any typical mobile processor core e.g. Intel, ARC, MIPS, etc.
The 6200 supports 4 different encoding modes allowing the optimal adaptation to available processing power; the lowest encoding level has the least complexity and therefore places a minimal load to the CPU, whereas the highest level, providing the best video quality, has the highest requirement for CPU resources. Even at the lowest encoding mode level, the 6200 out performs any software based H.263 or MPEG4 encoder currently used in cellular devices.
Licensed typically as object code compiled to the target processor core or environment, the encoder is delivered with Hantro's standard Application Programming Interface (API) or an operating system specific interface implementation such as: Symbian MDF, Microsoft DirectShow, OpenMax IL etc.
