NEC Electronics Introduces H.264 Chips for STBs

NEC Electronics introduced two new image-processing chipsets based on its enhanced multimedia architecture (EMMA) platform and optimized for set-top boxes (STBs) and digital TVs (DTVs) supporting the H.264 video compression standard. The EMMA3SL/SD system-on-chip (SoC) supports standard-definition video broadcasts, while the EMMA3SL/HD SoC supports high-definition broadcasts. The devices are the latest additions to NEC Electronics' family of H.264-compliant EMMA3 SoCs, which have achieved market success since 2006 in blue laser DVD players and high-definition TV (HDTV) products.

In addition to having an H.264-compliant video decoder, the devices combine all of the key functions needed to receive and decode digital broadcasts, including built-in digital signal processors (DSPs) that enable systems using Dolby Digital Plus or high-efficiency advanced audio coding (HE-AAC) to play back high-quality audio streams even at low transfer rates.http://www.necel.com
