    Modern reduced-instruction-set computer chips have features that lay the groundwork for great performance. They boast circuits that can work at clock frequencies ranging to 300 MHz, pipelines built to continually execute independent operations, and the ability to execute multiple instructions in a single clock cycle. The potential of this hardware can only be realized by sophisticated compiler tec... View full abstract»

    Europe's digital television plans downplay high-definition applications because of their previous defeat by an uninterested public. Europe's move from analog to digital television is still unfolding. It all began in 1986 with an Europe-wide research project that used digital technology to enhance analog television. Under the umbrella of Project EU-95 manufacturers and broadcasters throughout the r... View full abstract»

    Japan is the only country, so far, to be actually broadcasting high-definition television services. MUSE (multiple sub-Nyquist sampling encoding) is the basis for systems applying bandwidth compression to the transmission of both analog and digital signals. It encodes a signal of 1125 lines and 60 fields per second, a high-definition television (HDTV) signal into an 8-Hz bandwidth. Experimental MU... View full abstract»

    The one most likely system, to serve as the common meeting ground for phone and cable companies, is a hybrid network architecture of optical fibers and coaxial cables. As the industry evolves toward interactive services, three considerations will become paramount. One is the ability to deliver individualized programming to customers, and get responses from them as well. Here, the instantaneous net... View full abstract»

    As an aid to the TV receiver and VCR, the set-top box offers improved tuning and interactive hookups, but questions remain as to who will own and replace it. As a supplemental piece of television equipment, it can either compensate for a tuning deficiency or add capability like interactive electronics to a television receiver or a VCR. The author discusses the uses of the set-top box and its opera... View full abstract»
