DaVinci DSP powers up home media server
An advanced digital media adapter and home media server reference design is based on TI's DaVinci technology.
In addition, Nexvision has benefited from TI' s leading expertise in high performance analogue, by integrating TI's differentiated analogue companion products in the design of the Nexdome Dragonfly, such as video decoders, amplifiers, power LDOs, power DC/DC switches, USB switch and more.
The Dragonfly provides an open camera platform that is highly suited to large area surveillance applications such as public transportation, utility plants and medical centres.
These large areas need to rely on cameras that enable monitoring centres to deal more easily with the increase in the number of surveillance cameras with advanced features, such as object detection and tracking, traffic surveillance and automatic licence plate recognition.

Video decoder combines four in one
A new analogue-to-digital video decoder combines four independent video decoders into a single chip.
The compact size of the camera (130 x 130mm) makes installation fast and simple.
"The success of video surveillance has created a big challenge in terms of manageability", said M Lange, Business Development Manager for Nexvision.
"TI's DaVinci technology-based processor is the only embedded media controller on the market that integrates onto one chip the image processing power and peripherals needed for high-end video analysis and H.264 D1 real-time compression for streaming video over xDSL lines".
"As a result, we are able to offer our customers a compact, open and scalable platform that can easily be integrated into their surveillance network".
"The inherent integration of DaVinci technology and its open platform means companies can quickly and easily develop advanced security solutions, all for a reduced bill of materials (BOM)".
"Nexvision was able to design NexDome Dragonfly based on a single DaVinci technology-based processor within six months, a record design cycle time", said Cyril Clocher, Business Development Manager for TI's DSP group in Europe.
"In addition, the power and programmability of DaVinci technology-based processors allows customers to create unique, feature-rich video applications that were previously impossible".
The Nexdome Dragonfly has already been adopted by NMI Security, a market leader in the implementation of immersive technology.
"Nexvision is one of our strategic partners, and we are working together on several projects to introduce next generation immersive technology to the market", said Cliff Lunt, Marketing Director of NMI Security.
"Most recently, Nexvision has helped us successfully deploy an immersive system on the Stockholm Underground, and we continue to collaborate closely on further infrastructure projects in the UK".
The Nexdome Dragonfly features a 360 degree x180 immersive lens on a high resolution five megapixel CMOS 1/1.8 inch sensor, allowing the user to view a full scene or zoom in through a virtual pan/tilt/zoom (PTZ) display without diminishing image quality.
Depending on the video image sise, Dragonfly provides different video codecs ranging from MJPEG to MPEG4 Part 10 (H.264) from 6frame/s in high definition (HD) up to 30frame/s in VGA and D1.
It also supports streaming and standard network protocols such as RTP/RTCP, PPP, HTTP, FTP, SMTP, Telnet, DNS and DHCP, as well as offering a large choice of wired and wireless IP links such as Ethernet, Wi-Fi, Power line, xDSL and GPRS/Edge.
The TMS320DM644x architecture is a highly integrated system-on-chip (SoC) that has absorbed many of the external components required for digital video, dropping hardware BOM by as much as 50%.
The DM644x devices are based on TI's performance-leading TMS320C64x+ DSP core, an ARM926 processor, video accelerators, external memory/storage interfaces, and networking, video and audio peripherals that match consumer entertainment equipment specs.
With limitless scalability options, DaVinci technology helps video security manufacturers keep up with their ever-evolving industry.
