Analog Devices, Inc. (NYSE: ADI) is applying its signal processing expertise to the high-definition TV (HDTV) market by playing a leading role in bringing life-like audio and video to the living room and home theater. Analog and mixed-signal circuitry are defining today’s HDTV viewing experience by faithfully converting, conditioning and regulating the signals that result in superior, cinema-grade sound and images.
As the industry’s leading provider of multimedia signal processing technology, Analog Devices sets the foundation for HD picture and audio quality, while the company’s heritage in system-level design brings it into direct collaboration with top consumer electronics manufacturers. The result is that ADI’s analog and mixed-signal solutions are a driving force behind an evolving HD or “advanced TV” environment that includes plasma and LCD TVs, companion boxes like HD-DVD players, digital video recorders (DVRs) and audio/video receivers (AVRs), and the interconnects, or cables, required to send and receive HD content.
“Advanced TV is about much more than a great-looking flat panel display. Compelling HD images and multichannel audio require a full understanding of the analog video and audio signal chains,” said John Hussey, vice president of High Speed Signal Processing, Analog Devices. “But to take it a step further and deliver a ‘knock-out’ HD experience, you also need a level of system design experience that cuts across the entire HD spectrum. By combining our signal processing and system-level expertise, ADI is in a unique position to continue enhancing users’ digital home experiences.”
Analog Devices’ extensive product portfolio includes all the necessary video, audio and display inputs and outputs found in a complete HD-enabled system, including video decoders, encoders and filters, digital I/O and display electronics, and audio amplifiers and processors. In each area, ADI addresses design challenges that can compromise the crystal clear images and rich, true-to-life sound that consumers have come to expect from their HD electronics. By shaping and sharpening analog audio and video signals, ADI is helping digital media achieve its full potential by turning passive TV viewing into a truly immersive entertainment event.
Better Video Resolution Across All Formats
The realism and picture quality of HD video is what immediately stirs user interest, and yet the reality is that even in the era of digital broadcasting and HD programming, most of the televised content coming into the home still uses a standard-definition (SD) format. Ironically, a leading reason why consumers return their HDTVs is because of inferior image quality caused by the inability of the TV’s video decoder to provide high quality SD images. This becomes even more apparent given that most HDTVs have large screens that highlight any image artifacts caused by a poor quality video decoder. Analog Devices’ ADV718x and ADV74xx video decoder and ADA441x video filter families are designed to deliver the highest quality video image whenever decoding of SD content is required.
Big Audio Designed for Small Spaces
With the thinner profiles of today’s flat-panel TVs, designers have much less room to upgrade their systems for audio quality, which could result in “tinny” sound on micro speakers. Despite the trend toward slimmer TV form factors, Analog Devices’ SigmaDSP(R) audio processors incorporate sophisticated audio algorithms that compensate for smaller cabinets to render realistic audio that complements the viewing experience provided by large, flat-screen TVs.
Connecting the HD Experience
While demand grows for HDTV, so too does the need for HD-compliant components-DVD players, digital cameras, set-top boxes and gaming consoles-that users can seamlessly connect to their TVs. The HDMI(TM) (High-Definition Multimedia Interface) standard addresses this need by delivering uncompressed HD content via a single cable, allowing consumers a simple, seamless connection to view and hear the highest-quality images and sound. ADI is driving the availability of HDMI interconnect technologies with the industry’s broadest portfolio of HDMI receivers, transmitters and multiplexers. The receivers and transmitters ensure the HD signals are transferred from the component to the TV, without sacrificing quality, while the multiplexers allow users to connect multiple components to a single TV with lengths up to 20 meters.
Analog is Everywhere in Advanced TV
As more and more consumers discover the benefits of owning high-definition TVs and home theater systems, equipment manufacturers must continue to raise the performance of video, audio, and display interfaces. Consumers want “cinema-quality” images and audio from their large-screen HDTVs; they want connectivity to the Internet and to their cable set-top boxes, home audio systems and DVD players; and they want it all in systems that are easy-to-use and affordably priced. Analog Devices is committed to supplying all the high-performance Advanced TV interface ICs, including video encoders and decoders, analog and HDMI interfaces and audio processors and amplifiers, to enable the ultimate multimedia entertainment experience at home.
