Voice and video over IP

Analog Devices has taken the wraps off a new voice and video over IP chipset that can transform a standard television or video game console into an interactive voice and video communications terminal.

Analog Devices has taken the wraps off its new voice and video over IP chipset.

The ADSST-VC-7000, as the chipset is called, features up to 30 frames/second full-motion performance in CIF (352 x 288 pixels) and still images in 4CIF (704 x 576 pixels) resolution.

In operation, it uses a scaleable bit rate to enable operation over cable, xDSL, Ethernet, 3G or fibre. 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 ADI’s Blackfin DSP core with Micro Signal Architecture that includes an enhanced instruction set to support multimedia audio and video functionality.

The ADSST-VC-7000 includes the ITU standard compliant H.323 software stack with future support for the complete PacketCable (MGCP) specification and multi-channel codecs for typical PABX functionality.

It also supports the ITU standard compliant H.263 video codec with future support for H.26L codec and ITU standard compliant G.711, G.723.1 and G.729 audio codecs. Network echo cancellation G.168 is also supported along with Acoustic Echo Cancellation (AEC).

The chipset also includes a dedicated video I/O controller 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.

In use, the subsystem can transform a standard television or video game console into an interactive voice and video communications terminal.

The chipset is priced at $49.50 per unit in quantities of 10,000 and samples will be available in July. A voice and video over IP reference design kit, ADSST-VC-7000-RDK, will also be available in July and includes an evaluation board, documentation and schematics.
