MPEG4000WA MPEG-2/4 Codec with Watermark Authentication The MPEG4000WA is a 4-channel MPEG Codec on a single PC/104-Plus form factor. The MPEG4000WA provides a powerful and flexible solution for capturing and compressing up to four concurrent analog video inputs to MPEG-4, MPEG-2 and M- JPEG standards. On-board Watermark MPEG-4, MPEG-2 Authentication provides additional support and M-JPEG for evidential recording and law enforcement applications. recording of 4 PAL/NTSC channels The MPEG4000WA not only provides MPEG-2/4 compression but can also decompress and replay recordings from storage to display. It allows high quality real-time video and audio capture and compression from 1, 2 or 4 concurrent PAL/NTSC video sources to disk and simultaneously provides an additional path for uncompressed video for on- Advanced Micro Peripherals Ltd Advanced Micro Peripherals Inc Cambridge, CB6 2HY, England New York, NY10001, USA Tel (+44) 1353 659500 Tel (+1) 212 951 7205 Fax (+44) 1353 659600 Fax (+1) 212 951 7206 sales@ampltd.com sales@amp-usa.com http://www.ampltd.com http://www.amp-usa.com MPEG4000WA MPEG-2/4 Codec with Watermark Authentication screen Preview or optional downstream video analytics.

MPEG4000WA supports two main modes of video recording: Split Video The SVS mode supports 2 sub modes: Stream and Combined Video Stream.  4 x CIF size MPEG-4 each at full frame Split Video Stream rate In the Split Video Stream (SVS) mode the multiple channels being previewed  4 x D1 size MPEG-4 each at lower are captured and recorded as separate frame rate files or streams. Thus the When set to 4 x CIF the 4 inputs can be MPEG4000WA would output four files - concurrently recorded each at full one per channel. These streams are frame rate. Each channel is first independent and can subsequently be decimated to quarter screen size prior played back as separate MPEG streams to encoding. This results in 352 x 240 by appropriate hardware/software for NTSC and 352 x 288 for PAL. 4 Mobile MPEG-2/4 Record and Playback System Advanced Micro Peripherals Ltd Advanced Micro Peripherals Inc Cambridge, CB6 2HY, England New York, NY10001, USA Tel (+44) 1353 659500 Tel (+1) 212 951 7205 Fax (+44) 1353 659600 Fax (+1) 212 951 7206 sales@ampltd.com sales@amp-usa.com http://www.ampltd.com http://www.amp-usa.com MPEG4000WA Operation Summary MPEG-2/4 Codec with Watermark Authentication The 4 x D1 sub-mode allows 4 inputs to and the resulting MPEG-4 file can be be recorded each at full D1 size with played as a single MPEG-4 stream by input at less than full frame rate. 4 full appropriate hardware/software D1 size ( 720 x 480 for NTSC and 720 x decoders. 576 for PAL) video is recorded in this Watermark Authentication mode.
