Tool transmits HD video over any transport source

Keywords:HD home entertainment? UWB? Wi-Fi? HDMI?

The rapid growth of high-definition (HD) home entertainment systems has made the connections between an increasing number of sources and displays more difficult. HDMI cables support a limited distance, and content protection restrictions preclude most of the traditional interconnect solutions.

In response to this, Analog Devices' HDAnywhere networked entertainment solution is claimed to be the only solution that works with any source, over any common transport. It enables connections to wall-mounted displays without cables, ceiling mounted projectors without putting wires through the walls and TVs in other parts of the house without running new wires.

Intelligent design
HDAnywhere is based on ADI's Wavescale compression, the same JPEG2000-based technology used in digital cinema and broadcast TV systems. Wavescale technology provides unique advantages in video quality, transmission robustness, scalability, low latency and instantaneous data rate adjustment.

The HDAnywhere system compresses video in real time, encrypts the stream and provides it to a UWB, Wi-Fi, powerline, phoneline or coax modemall without visual interruptions. The receiver decrypts and decompresses the stream and produces an HDMI output, ready to be connected to any HD display. It can accept video and audio in any common format, including standard definition composite and component, and HD content in analog component or an uncompressed digital form. This addresses evolving entertainment systems, which incorporate a mix of HD and legacy components.

ADI's HDAnywhere reference design includes schematics, PCB layouts and firmware for a complete system design. It can be configured to support resolutions up to 1,080i or, with additional hardware, 1,080p video. It can be easily modified to add or delete input and output ports to meet specific cost and functionality targets. One end of the link can be embedded into a video source or display, adding interconnect flexibility to the device while minimizing overall cost.

"Different video transport options offer various advantages: some are good for in-room transmission, while others may provide better coverage for an entire house," said Bill Bucklen, director, advanced television segment at ADI. "The HDAnywhere networked entertainment platform is the only solution that adapts to all wired and wireless networking technologies while maintaining optimal video quality."

Leveraging ADI's broad line of video and audio products in its Advantiv portfolio, the HDAnywhere platform offers the flexibility to configure a system meeting particular cost and feature objectives with components tailored to work together seamlessly. The HDAnywhere networked entertainment reference design is available to qualified customers from ADI.

Advanced TV
Because the signal processing performance requirements for HD video, audio and interconnect functions are significantly higher than for standard-definition TVs, ADI offers the Advantiv advanced TV portfolio, providing cost-effective analog, digital and mixed-signal solutions to the most difficult multiformat ATV design challenges.

Supported by ADI's system-level experts, these customer-driven solutions enable the latest in HD home entertainment systems. ADI offers a broad range of industry-certified solutions for advanced TV applications, with products that enable rewarding experiences for consumers enjoying the latest high-definition TVs, DVD players, digital video recorders, A/V receivers, camcorders and cable and satellite STBs.
