Multimedia SoC Platform Targeting Digital Surveillance, Mega-Pixel IP Camera and Multi-Channel Video Streaming Devices

The GM8180 is a highly integrated H.264/MPEG-4/JPEG SoC solution targeting Internet digital video applications especially on IP surveillance and IPTV station applications. With the pure hardwired video codec architecture, the max. 500 MHz CPU can be used for computing of audio encoding or image analysis in intelligent surveillance applications, such as object or face detection The H.264 encoder supports real-time 1280 x 720 pixels @ 30 fps or 1280 x 960 pixels @ 22.5 fps bitstream. With flexible video codec engine design, the GM8180 also supports multi-channel compression or de-compression of multi-channel video servers, PCI encoder/decoder adaptors or DVRs. GM8180 Linux SDK is comprised of five components: Linux 2.6.14 , peripheral drivers, network protocol stack, sample video application software and web server/CGI interface. GM Streaming Media (GSM) is an IP camera/IPTV station application software package. It integrates the video/audio codec algorithm and network streaming protocols with low latency tuning and dynamic bit rate control to adapt to the dynamic internet traffic. Combined with GSM and Linux SDK, it is a turnkey software solution for customers with the UI interface provided for differentiation.
