Analog Devices Inc. has announced the availability of the ADSST-VC-7000 chipset that delivers real-time voice and video over IP to cable, xDSL, Ethernet, 3G, or fiber-based networks.

The chipset offers up to 30fps full-motion performance in CIF (355x288 pixels) resolution and still images in 4CIF (704x576 pixels) resolution. It also supports CCIR656-compatible digital or NTSC/PAL analog composite cameras and enables direct connection to a standard NTSC/PAL television or a QVGA LCD panel.

At the heart of the ADSST-VC-7000 chipset is the company's Blackfin DSP core with Micro Signal Architecture that includes an enhanced instruction set to support multimedia A/V functionality.

The chipset also includes the ITU-compliant H.323 software stack with future support for the complete PacketCable specification and multi-channel codecs for typical PABX functionality. It also supports the H.263 video codec with future support for H.26L codec, and G.711, G.723.1, and G.729 audio codecs. Network echo cancellation G.168 is also supported along with acoustic echo cancellation.

A dedicated video I/O controller is also included to form a complete subsystem that does not require a PC to add real-time voice and video communications capability to consumer products connected to broadband networks. This allows standard television receivers or video game console to be transformed into an interactive voice and video communications terminal.

The chipset is priced at $49.50 per unit in quantities of 10,000. A reference design kit , the ADSST-VC-7000-RDK, is also available.
