Top rivals agree on unified system for advanced TV; debut in U.S. is hastened; bright and clear digital picture would enhance viewing and interactive technologies

Article Abstract:

The three consortia competing for Federal Communications Commission approval of their high-definition television technologies have agree to combine their approaches into a single standard. The consortia, one comprising the General Instrument Corp and the Massachusetts Institute of Technology, another including AT&T and Zenith Electronics, and one led by Philips Electronics, expect to develop a prototype within nine months and to have products to market by 1995. The standard makes concessions to the computer and television industries. Computer compatibility is ensured by the adoption of progressive scanning to reduce flicker and by square pixels. However, since television manufacturers and broadcasters complained about the cost of progressive scanning, the system will be capable of decoding interlaced broadcasts and providing five resolutions of progressive scan.

2 competitors in pact on advanced TV plan

Article Abstract:

The Massachusetts Institute of Technology (MIT) and the General Instruments Corp join forces to develop a standard for high-definition television (HDTV). General Instruments, which makes encryption devices for cable television systems, previously were competitors. They will now combine their efforts, hoping their technology will be chosen as the US HDTV standard by the US Federal Communications Commission (FCC). The FCC will decide on a HDTV standard in 1993. MIT and General Instruments are working on an all-digital standard. General Instruments became the first to propose an all-digital standard, and MIT now believes it can alter its previous system to use all digital. The two organizations will submit two versions of an HDTV standard for testing.
