NEC Electronics has an image-processing system-on-chip (SoC) device for set-top boxes which is compliant with H.264 high definition (HD), the next-generation image-compression standard.

It also supports multi-format video used for internet-protocol television (IP TV) STBs, such as DivX, VC-1, and WMV.

The EMMA3SL/P integrates receive and decode functions, including MPEG-2 HD audio/video decoders, transport-stream demultiplexers, as well as display controllers for enhanced display and graphics features.

The SoC includes these features: multi-format video support for IP TV STBs, in addition to support for the H.264 HD standard and China’s AVS.

NEC Electronics introduced two EMMA devices in January 2009, the EMMA3SL/LP and EMMA3SL/L SoCs, to the wider H.264 STB market.
