The MPEG4000WA is a 4-channel MPEG / M-JPEG Codec on a single PC/104-Plus (pc104+) form factor module. The MPEG4000WA provides a powerful and flexible solution for capturing and compressing up to 4 concurrent analog video inputs to MPEG-4, MPEG-2 and M-JPEG standards. The on-board Watermark Authentication provides additional support for evidential recording and law enforcement applications. The MPEG4000WA not only provides MPEG compression but can also decompress and playback recordings from storage to display. The MPEG4000WA allows high quality real-time video / audio capture and compression from (up to) 4 concurrent NTSC or PAL video sources while at the same time allowing the data to be stored to disk and provide a preview screen for incoming video. The high performance MPEG video data compression and reduced bus utilization allows up to four MPEG4000WA cards to be fitted in a PC/104-Plus system to provide up to 16 concurrent video streams to disk or across a network.

Software Development Kits

The MPEG4000WA is supported by comprehensive and well supported software development kits (SDKs) for video recording and video streaming. The SDKs are designed to significantly reduce development time in Windows and Linux environments and include support libraries, drivers and example applications to help developers fully utilize the MPEG4000WA features in complex video compression / overlay applications.

The standard Video Recording SDK and sample applications are supplied free of charge with each board and includes the services of our technical support team. The Video Streaming SDK is available for a one-time fee and enables real time streaming of compressed video data over an IP network.

The standard SDKs are available for x86 based embedded PC platforms however, we also offer SDKs suitable for PC/104-Plus based PowerPC and ARM platforms. Please contact our sales team to discuss your requirements.
