For component suppliers, high definition (HD) means more than just televisions.
Today’s suppliers are cranking out video processors and codecs for HD satellite receivers, media centers, DVD players, gaming consoles, camcorders and more.
Moreover, a few are even looking beyond high definition and developing components or the next generation of advanced video products.
“We see advanced TV as including digital still cameras of six, eight and 10 megapixels,” says Doug Barto, strategic marketing manager for the advanced TV segment at Analog Devices Inc. “We see it including high definition video camcorders that will slice through the $1,000 barrier, media center PCs, high resolution 1440p displays and even 3-D TVs.”
Indeed, suppliers are making components for next-generation products. Here, we’ve gathered three such components from Analog Devices, Texas Instruments and Metalink Ltd. All are made for going beyond today’s high definition televisions, into a new world of more capable, higher resolution video products.
TI'S HD VIDEO FOR PORTABLE PRODUCTS
Optimized for HD video, Texas Instruments’ DM355 processor achieves its performance by integrating a video/imaging co-processor to achieve a sub-$10 price and enable ultra-low power consumption. The co-processor provides HD MPEG-4 SP encode or decode at 720p and 30 frames per sec and JPEG encode or decode at 50 megapixels per sec. The video processing subsystem integrates a preview engine, histogram, re-sizer and on-screen display all in hardware. It also provides the equivalent of 400 MHz of digital signal processing (DSP) to achieve HD video.
ANALOG DEVICES' VIDEO CODEC
ADI’s ADV216 video codec features the company’s Wavescale compression technology, based on the JPEG2000 video compression standard. By tailoring the technology for consumer video applications, ADI has developed a solution that enables wireless HD signal transmissions while eliminating the artifacts and error intolerance of alternative video solutions. The ADV216 includes SURF (spatial ultra-efficient recursive filtering) wavelet technology, which enables real-time compression and resolution scalability without the need for external memory. The ADV216 also supports low latency, thus improving consumers’ video gaming experiences and enabling fast, remote-control response.
METALINK'S WIRELESS HDTV CHIPSET
With its 2.4-GHz and 5-GHz chipsets, Metalink plans to provide the solutions necessary for sending three MPEG2 HDTV streams at 60 Mbps throughout the home, with coverage as far as 60 ft. The key to its technology is Metalink’s commitment to the use of the new IEEE 802.11n standard. The new standard, which boosts data throughput by employing multiple transmitter and receiver antennae, reportedly gives the company a leg up on competitors that have tried to implement similar technology using older versions of 802.11. “The new standard gives us a bigger pipe and a better infrastructure,” says Barry Volinskey, vice president of marketing for Metalink.
