SoCs tout built-in support for H.264 video compression standard

Kawasaki, Japan & Duesseldorf, Germany & Santa Clara, Calif.—NEC Electronics has introduced two image-processing devices based on its enhanced multimedia architecture (EMMA) platform.

The EMMA3SL/HD and EMMA3SL/SD devices enable users to build set-top boxes and digital TVs (DTVs) with next-generation H.264 video compression standard, which offers twice the compression ratio as the current MPEG2 standard. The EMMA3SL/SD SoC supports standard-definition video broadcasts, while the EMMA3SL/HD SoC supports high-definition broadcasts.

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 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.

A built-in Enhanced Host Controller Interface (EHCI)-compliant USB 2.0 host controller and IEEE 802.3/802.3u/802.3x-compliant Ethernet media access controller (MAC) replace the external components traditionally required. This integration enables low-cost connection to external devices and networks and makes it easy for systems to import and process video and audio streams.

The EMMA3SL/HD SoC includes a built-in HDMI-compliant interface for digital transmission of uncompressed video and audio streams, a built-in deinterlacer to convert interlaced signals into progressive signals and a built-in fast D/A converter to produce high-definition signal output.

Pricing: Starts at $50 for the EMMA3SL/HD and $40 for the EMMA3SL/SD.
Availability: Now in sample quantities; volume production is scheduled to begin by the third quarter of 2008.
