Multimedia SoC Solution Targeting Digital Surveillance, DVR and Video Streaming Devices |
|
GM8120 is a highly integrated MPEG-4/JPEG SoC solution for Internet digital video applications. The main thrust of GM8120 is the MPEG-4/JPEG/H.263 video codec hardwire engine with a powerful and highly-integrated 240 MHz RISC processor containing an 8k I-cache and an 8k D-cache. The engine supports real-time MPEG-4 encoding/decoding with target applications such as Internet surveillance camera, digital video recorder, digital media adaptor, portable media player, IP set-top box, media gateway, network attached storage, and TV captured card. GM8120 takes image quality to a new level, while delivering D1/VGA streaming video up to 30 fps.
GM8120 is capable of supporting CCIR input and output signals. The SoC provides quick and easy PC attachment and Internet connectivity by offering industry standard video encoder/decoder interfaces, removable storage devices with USB OTG and 802.3 MAC support. |
