Advanced Micro Peripherals has developed a watermark authentication MPEG4 video codec which will add watermark authentication and other functions to a multi-channel MPEG4 core for the PC/104 form factor.

MPEG4000WA’s watermark authentication algorithm employs a 128-bit HMAC-MD5 keyed Hash Authentication Code which can simultaneously verify both the integrity and authenticity of the transported data.

It uses a 32-bit PCI architecture, encodes up to four concurrent full-size real-time analogue inputs from live PAL or NTSC video and audio sources using either MPEG4 or Motion JPEG (MJPEG) compression.  It can also decode and playback MPEG4 or MJPEG video and audio recordings from storage to display.

The MPEG4000WA can record 4 full size D1 inputs each at quarter frame rate or each input at full frame rate but at quarter size.

Advanced Micro Peripherals is an ISO9001 registered designer and supplier of high performance and rugged PC/104 and PC/104+ embedded products, specialising in embedded video products and ultra-low power devices. Products include video capture and compression cards, communications controllers and ultra low power computers based around the Transmeta Crusoe processor running at 1GHz.
