Campbell, Calif. — Uncompressed multichannel wireless-audio technology developed by fabless semiconductor designerFocus Enhancementsis a step closer to appearing in home-audio products.
The company signed an agreement with ODM supplier ANAM Electronics to include Focus’Summit ICinto A/V receivers (AVRs) that it designs and manufactures.
Focus’s technology,unveiledlate last year, is promoted as overcoming the sound quality, interference, latency and cost challenges associated with other wireless technologies designed for multichannel home theaters. It’s designed for use in a variety of consumer electronics products, including TVs, DVD and Blu-ray players, home theater in a box (HTiB) systems, preamps and game consoles.
The technology promises 7.1-channel sound quality said to be virtually indistinguishable from wired quality, and it’s affordable enough for use in midprice HTiBs, the company said. Summit achieves its quality goals by, among other things, transmitting uncompressed 48kHz/24-bit PCM over the air, using forward error correction to overcome latency problems, and using the uncongested 5.1-5.8GHz U-NII band. That spectrum, which features 23 non-overlapping channels, was recently approved by the International Telecommunications Union (ITU) for worldwide unlicensed use near the IEEE 802.11a/n wireless-network band.
