Bringing more flexibility and features to low-end video security applications, Texas Instruments Incorporated Inc. and Techwell Inc. have collaborated to create technology for low-cost digital video recorder (DVR) security systems.

The new solution, which combines TI's TMS320DM6446 digital video processor based on DaVinci technology with the four-channel video and audio controller from Techwell, will help manufacturers of video security systems implement next-generation, low-cost DVR products.

The DVR security technology enables the development of security applications using video recording and multiple camera sources. The DM6446 evaluation module is connected to Techwell's TW2835 video and audio decoder, which produces four channels of video output at CIF resolution (352 x 288 pixels). In order to minimize bandwidth and storage requirements, each channel is compressed using the MPEG-4 algorithm at 30fps. The TW2835 multiplexes the four channels as an input for the DM6446, which reads and processes the information through a single, high-speed video port.

"The TI-Techwell demo ensures OEMs that they can build their next-generation, low-cost DVRs with extended digital video security functionality," said Danny Petkevich, video security business manager, TI. "The high performance of the DM6446 digital media processor enables them to design multiple-source video and recording systems quickly and cost-effectively."
