Consumer electronics

Article Abstract:

Significant 1991 trends and events in consumer electronics include the gradual move towards implementation of high-definition television (HDTV) in the US, increasing channel capacity on US cable systems, emerging competition between multiple digital recording technologies and a move to digital audio radio (DAR). Testing of proposed US HDTV technologies commenced at the Advanced Television Test Center, and the details of the testing are briefly described. Cable television systems are beginning to increase their channel capacities to 1-GHz and 150 channels through the use of optical-fiber cable, though proposed compression technologies could increase capacity to 390 channels. Philips Consumer Electronics and Sony Corp introduced digital audio recording systems, respectively the Digital Compact Cassette and the Mini Disc System, whose recording technologies are described. Consulting firm Pres Almon H. Clegg describes the potential broadcasting systems for delivery of DAR.

Article Abstract:

General Instrument Corp's DigiCipher system for transmitting a full high-definition television (HDTV) signal in digital format over a standard 6-MHz television channel heated up the US HDTV industry in 1990. DigiCipher may become the simulcast HDTV standard that the Federal Communications Commission (FCC) requires have a single broadcast channel carry a standard National Television System Committee (NTSC) channel for reception on existing television receivers and a second channel carry the HDTV signal for HDTV receivers. All-digital television broadcast systems are being developed by the Advanced Television Research Consortium and other US groups as well; an FCC decision on an HDTV standard is not expected before mid-1993. HDTV developments in Japan and Europe, home theater developments and artificial intelligence use by consumer electronics devices are discussed.

Article Abstract:

Telecommunications and high definition television (HDTV) had gains in 1992 as government regulations came closer to standardization and as new technologies hit the market. The AT&T Videophone 2500 sends and receives full-color limited motion video over existing phone lines and operates at the same price as voice calls. Videophone is plugged into standard phone power outlets and has a fold-up panel that holds a 3.3-inch diagonal LCD display and camera lens; price for the device is $1,499. In the area of HDTV the US Federal Communications Commission anticipates the selection of a standard by the end of 1993; the schedule calls for a changeover to HDTV broadcast by the year 2008 and could obsolete all current-design TV receivers.
