Compression codec enables HD wireless transmission

Expanding its Advantiv advanced television solutions portfolio, Analog Devices, Inc., has introduced a video compression CODEC that enables a rich viewing experience for consumers with high-definition home entertainment systems by enabling the wireless transmission of high-definition (HD) video in real-time—without any loss in picture quality—over home connections. A compact and complete solution for compression and decompression of HD video, the CODEC distributes vivid images in high-volume consumer applications, such as the latest flat-panel TVs, leading-edge game consoles, and next-generation DVD players, without the tangle of cables common to today's hard-wired home entertainment systems.

The ADV216 video CODEC features Analog Devices' Wavescale compression technology, which is based on the JPEG2000 video compression standard. JPEG2000 is commonly used in high-end professional imaging applications, including digital cinema, broadcast television production, satellite and medical imaging, and security systems. By tailoring its Wavescale compression technology for consumer video applications, ADI has developed a solution that enables high-quality wireless HD signal transmission while eliminating the artifacts and error intolerance of alternative, MPEG-based video solutions. The ADV216 also includes ADI's proprietary SURF' (spatial ultra-efficient recursive filtering) wavelet technology, which enables real-time compression and resolution scalability without the need for external memory. In addition to delivering crystal-clear, uninterrupted HD content to TVs and HD companion boxes, the ADV216 supports low latency, which improves consumers' video gaming experience and enables fast remote-control response.

The ADV216 features an API (application program interface) that simplifies system design by allowing compressed data rates to be managed on a frame-by-frame basis, which frees HDTV manufacturers from having to design to worst-case transmission conditions. The CODEC also adapts to changing conditions, such as wireless data rate changes due to interference or other factors, without interrupting or dropping video frames. The ADV216 supports HDMI (High-Definition Multimedia Interface) and Wireless for HDMI applications.

According to Bill Bucklen, director, Advanced Television Segment, Analog Devices, “The ADV216 enables HD quality video over high-bandwidth wireless standards, including UWB and 802.11n. Moreover, it supports wired HD video transports, including coaxial and powerline cables, which gives manufacturers the ability to use one device for wireless and fixed-wire HD video applications.”

Pricing and Availability
The ADV216 Wavescale video compression CODEC is available in a 13 mm – 13 mm BGA (ball grid array) package and is priced at $17.35 per unit in 1,000-unit quantities. For more information, visit

ADI's Wavescale Compression Technology
Wavescale compression technology is ADI's implementation of the JPEG2000 open standard, an international image compression standard based on wavelet transforms that was established in January 2001. Analog Devices' Wavescale compression technology significantly reduces the visual impact of errors that occur in video transmission channels, producing stunning HD images, even in noisy environments. The primary benefits of Wavescale compression technology for home applications are bit-rate scalability, error resiliency, low latency and resolution scalability. Competing compression solutions, such as MPEG-2 and other temporal-based schemes, compress multiple frames as a group, thus a single transmission error can often affect most of the frames in that group, resulting in persistent video disruption. Wavescale compression technology compresses each frame independently, so transmission errors affect only a single frame, and do not propagate through subsequent images.

“Since a wavelet transform is employed in place of the discrete cosine transform used in MPEG-type compression, errors that do occur are usually not noticeable,” said Bill Bucklen. “End-to-end latency is very low because there is no inter-frame processing. This is particularly important in HDTV applications as low latency allows for instant remote control response and minimal lip sync processing. Wavescale compression technology solutions allow the extraction, compression and transmission of video images at varying resolutions without further signal processing. This means the same compressed stream can be used simultaneously by multiple displays of different resolutions.”

Analog Devices in 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 television portfolio, providing cost-effective analog, digital, and mixed-signal solutions to the most difficult multi-format ATV design challenges. Supported by ADI's system-level experts, these customer-driven solutions enable the latest in HD home entertainment systems. Analog Devices offers a broad range of industry-certified solutions for advanced television (ATV) applications, with products that enable rewarding experiences for consumers enjoying the latest HD TVs, DVD players, digital video recorders, audio/video receivers, camcorders and cable and satellite set-top boxes.
