Overview

The WW508 is a multi-stream H.264 video codec, specifically optimized for video surveillance applications, such as DVRs, video servers and multi-stream IP camera head-ends. The deployment of H.264 delivers more efficient compression than MJPEG and MPEG-4.

The 8 bi-directional video ports support spatially and temporally multiplexed video streams, allowing the WW508 to process a total of 32 CIF or 8 D1 streams at 30 frames/sec simultaneously. Video input ports can dynamically transrate and transsize the input video streams. The large number of ports allows very cost-effective DVR or multi-stream IP camera head-end implementations without the need for expensive video multiplexers.

Through Super Low Latency Technology™ (SLL Technology™) the WW508 achieves sub 40ms encode-decode latency for multi-stream D1 processing. These latency numbers are the lowest in the industry and key requirement for real-time PTZ camera control and for securing premises instantly upon security breaches. The WW508 has features optimized for surveillance applications, such as the ability to selectively blank/block video areas to hide sensitive information, e.g. customer ATM pin codes, and motion vector and SAD information extraction for video analytics purposes.
