Audio Processor enables 50 hr of continuous music playback
Designed as companion chip to application processor on mobile phones, single-chip uPD99910 integrates CPU and DSP that appropriate and optimize music playback function of application processor to conserve power and extended listening period. In addition to SD Memory Card interface, product provides interface dedicated to copyright protection media and supports Content Protection for Recordable Media (CPRM) copyright protection technology.
Enables 50 Hours of Continuous Music Playback on Mobile Phones
SANTA CLARA, Calif., March 20 / -- NEC Electronics America, Inc. today announced the launch of the first product in the company's new AP series of audio processors that enables 50 hours of continuous music playback on mobile phones. The single-chip uPD99910 audio processor integrates a central processing unit (CPU) and digital signal processor (DSP) dedicated to music playback and an interface dedicated to copyright protection media.
Designed to be a companion chip to an application processor, NEC Electronics' uPD99910 device appropriates and optimizes the music playback function of the application processor, incorporates an SD Memory Card interface and supports Content Protection for Recordable Media (CPRM) copyright protection technology whose SD-Audio function enables music data to be downloaded and played without copyright infringement. The power saved by having the playback-dedicated CPU and DSP operate in place of the application processor allows 50 hours of continuous music to be played back using existing resources such as user interface software. By having these features integrated on a single chip, the new processor allows manufacturers to enhance mobile phone performance while reducing time to market and costs.
Winegard to form a new mobile Internet antennae systems company
Winegard Company has recently established DATA TECH, LLC, a new company dedicated to mobile Internet antennae products. Headquartered in Salt Lake City, Utah, DATA TECH will develop technologies and associated products that deliver Internet and data communications within the domestic and international mobile markets.
"Just as the Internet has transformed modern day living over the last 15 years, mobility of the Internet and all of its applications will revolutionize the 21st century for business and consumer alike," states Randy Winegard, President/CEO of Winegard Company. "We are excited to be at the forefront of this market."
DATA TECH will launch its first product, a nomadic/mobile Internet antennae system designed for virtually any satellite send and receive platform, in the fall of 2004. This flagship product, available in a .74, .75, and 1.2 mobile antennae solution, will provide a user-friendly environment with rapid signal acquisition, and will be in full compliance with all FCC regulations for sending and transmitting in a mobile environment.
"Mobile Internet technology is all about the freedom and affordability of high speed communication, anytime, anywhere," says DATA TECH President Reed Brown. "People are constantly on the go and are in continual need of access to information. We will be offering these products to Winegard's recreational vehicle and automotive customers, and to newer market segments as well."
Sound improvements: an inside look at the new technologies that will shape the future of automotive entertainment
The expectations of both drivers and passengers for electronic entertainment, communications and information have escalated since the introduction of the pioneering first practical auto radio, the Motorola branded AM car radio introduced in the 1930s by Galvin Manufacturing (who later changed their name to Motorola).
The latest cars, SUVs and trucks offer stock and premium entertainment packages beyond our wildest visions. DVD video with multiple fold fold-down LCD panel displays with fiber optic interconnection, navigation systems, Satellite/HD radio, mobile video and, THX surround sound.
Next generation electronic features and functionality will lend themselves to OEM equipped vehicles as designers struggle with size and weight reduction, long-term stability, environmental robustness, integration into larger assemblies and subsystems and the occasional request for cost down.
The Final Frontier
Interior space continues to get scarce and autosound aftermarket installers this year are confronted with a number of vehicles with none of the usual odd corners to install amplifiers, subwoofers and other electronic boxes. But while the OE interior engineers get to the scene first, the land grab is just as intense. While dashboard space is being eaten up by climate controls, air conditioning, air bags, navigation displays and so on, audio engineers are finding innovative technology in both audio electronics and speakers that provide significant space savings.
Until Panasonic introduced the first in-dash receiver utilizing high-power switching amplifiers this year (MXE CQ-C9800U CD receiver, 60Wx 4). the commonmost head end units was were limited in fewer than 20 watts per channel (with Alpine's V-Drive the former champion, at 26W x 4). Additional power and channels required amplifiers under the seat, built onto the speakers, or crammed into some other available space.
Higher power, in-dash head-end units have three significant implications for OEM designers. The Panasonic head unit offers more real power then many outboard amplifiers. A big impact is the space and heat savings. With the extra space created by getting rid of the heat sinks, OEMs can add better digital signal processors and bigger LCD monitors.
