H.264 encoder

Lightem LDMB88H.264 encoder has been developed and promoted to improve encoding efficiency, decrease encoding time delay, optimize algorithm, increase the anti-bit- error-ratio and enhance the image quality to enable it to realize better image compression effect with lower bit rate. With advanced video preconditioning technique and high efficient video encoding algorithm, it is able to effectively promote utilization of the available bandwidth and greatly reduce the DTV transmission cost for the operators. DMB-8800 supplies high quality but low bit rate video and audio signal for digital TV broadcasting system, mobile telephone TV system and IPTV system.
