Implement Voice And Video Over IP That's DSP-Free

It's the year of Voice over Internet Protocol (VoIP). Manufacturers are building VoIP phones, analog terminal adapters, gateways, and Wi-Fi phones. Typically, these companies use a standard general-purpose processor with a DSP chip to implement the VoIP protocol. But now, a DSP-free software approach significantly reduces the cost, consumption, footprint, and design time in implementing IP voice—and video.

Version 2.0 of Trinity Convergence's VeriCall Edge software implements the full VoIP protocol on a standard processor such as ARM, MIPS, Starcore, and most of the Freescale processors (e.g., PowerPC, iMX21 multimedia processor). It runs under embedded and Metro Linux, but it soon will be available for the Windows CE and Symbian operating systems. The software takes about one half-megabyte of memory.

VeriCall Edge 2.0 permits voice and video over IP, otherwise known as V2IP. Its full video library includes H.263, MPEG-4, CIF, QCIF, and sub-QCIF. The video software also implements rotate, X/Y, mirror, picture-in-picture (PIP), and A/V sync. This opens the door for video features in home-based video phone and video cell-phone designs. It permits full 30-frame/s video, which is essential for applications like video conferencing.

The VeriCall Edge 2.0 V2IP software will reduce bill-of-materials costs, leading to a lower product price. Reduced power consumption and smaller size are other benefits. Designers who lack VoIP and DSP expertise will find the software user-friendly. The complete product is available now.
