High-performance, low-cost video processing helps surveillance applications keep a watchful eye

Norwood, MA (11/20/2006) - To stay safe and sound, users in a wide variety of commercial and residential settings are turning to surveillance monitoring over Internet Protocol (IP) networks. Now a network digital video recorder (DVR) from Beijing Avinfo Technology, Inc. (Avinfo) is using the Blackfin® processor from Analog Devices, Inc. (NYSE: ADI) in a surveillance solution that enables audio and video recording, as well as remote viewing, recording, and playback over a secure IP network. China-based Avinfo, which provides networked multimedia management solutions for remote monitoring and security surveillance, chose Blackfin for its blend of competitive price/performance, integrated peripherals, and ease of development.

Support for high-end surveillance scenarios is key for Avinfo’s Av1320 network DVR, which features motion detection and is capable of notifying authorities of intruders via the Internet. Avinfo reports that the 400 MHz Blackfin ADSP-BF532 supplies more performance for less cost than a competing digital signal processor (DSP) the company used in the past. What’s more, Blackfin integrates the industry-standard interfaces that Avinfo required for the Av1320.

The high level of peripheral integration offered by Blackfin -- which alleviates the need for costly external components and speeds development time -- helped Avinfo complete the first demo unit of the Av1320 in just 29 days.

Moreover, the combination of Blackfin’s horsepower and the inclusion of two multiplier/accumulators (MACs), two 40-bit ALUs, four video ALUs, and a single shifter allows for very efficient processing of industry-standard video codecs such as JPEG, MPEG, Windows Media, and H.263/264 in a variety of screen sizes and frame rates.

Avinfo also used ADI’s VisualDSP++®, an easy-to-install and easy-to-use integrated software development and debugging environment (IDDE), to efficiently manage the project from start to finish.

The Av1320 is a one-channel video/audio network DVR system. It includes DVR software and offers optional IP cameras. The DVR records up to 25 frames per second (fps) PAL and 30 fps NTSC in real time. Digital (D1), Common Image Format (CIF), and Quarter CIF (QCIF) resolution video formats are supported.

“Our network DVR depends on multimedia performance to be able to capture and relay surveillance video in real time,” said Shi Guang Lv, Assistant of Avinfo General Manager. “Blackfin provides that high performance, plus industry-standard interfaces and a development environment that proved valuable in keeping our bill-of-materials cost down and accelerating our time to market.”

“From its digital signal processing performance, to its peripheral integration, to its extensive support for audio/video codecs, to its development environment -- Blackfin has the demanding territory of networked digital media applications covered,” said John Croteau, general manager, Convergent Platforms and Services Group, Analog Devices.

A Convergent Future Demands Blackfin-Class Processing
Analog Devices’ Blackfin embodies a new breed of 16/32-bit embedded processor with the industry’s highest performance and power efficiency for applications where a convergence of capabilities -- multi-format audio, video, voice and image processing; multi-mode baseband and packet processing; and real-time security and control processing -- are critical. It is this powerful combination of software flexibility and scalability that has gained Blackfin widespread adoption in convergent applications such as digital home entertainment; networked and streaming media; automotive telematics and infotainment; and digital radio and mobile TV.
