Dallas, Texas – Betting the game on what they think will be the next big thing after VoIP, cell phones and broadband cable, Texas Instruments and Wintech Digital Systems Technology Corp. have developed the Videophone Development Platform (VDP) for implementing point-to-point IP-based videophones.  

According to David Dong, president, Wintech, traditional barriers to adoption of videophones include jerky video quality and high unit cost.

 “However, the introduction of new video codecs which require half the bandwidth for video transfers,” he said, “the continuing penetration of IP broadband connectivity and the availability of single-chip encode and decode implementation has overcome these last-mile barriers. 

“The increasing market demand for IP consumer videophones with superior audio and video quality is driving the advent of new and improved systems.” 

Further pushing deployment of videophones, he said, are the many large carriers have announced plans to roll out IP videophones and related services for small- to mid-sized businesses and individuals with broadband Internet connections.

Wainhouse Research projects that overall the personal videoconferencing market will grow from about $21 million in 2003 to just shy of $180 million in 2008, a compounded growth rate of about 53 percent. 

Dong said the VDP from TI and Wintech is an integrated hardware/software development platform reducing both design complexity and total system bill of materials, including everything developers need to begin designing point-to-point videophone systems immediately.

All application system software runs on TI's 600 MHz DSP-based TMS320DM643 digital media processor, including audio/video compression, networking stacks and control protocols. 

From a hardware perspective, he said, the modular VDP offers a complete development environment for designing and building consumer videophones. Developers can connect the development boards over a live network and/or the Internet to test under real-world operating conditions, and the VDP is easily configured for different video telephony applications.  

The hardware platform includes external memory and a variety of peripherals and audio/video interfaces, network connectivity and communication interfaces. 

The key to the flexibility of the VDP is the DM643 digital media processor, which incorporates industry protocol standards so products developed with the VDP are able to interoperate with other videophones and the existing IP infrastructure.  

In addition to complementary TI analog technology, including the TVP5150 video decoder and AIC23 audio codec, the VDP includes all the software necessary to evaluate, design and test video telephony endpoints, including video and voice codecs, integrated reference frameworks, communications stack and network protocols. 

Available now for $6,950, the comprehensive VDP includes two DM643 boards, two five- inch LCDs, two cameras, network switch/hub and complete ready-to-use application software.
