    The installed copper pair of the telephone access network can be a bottleneck for the provision of the digital "telephony+video+data services" of the future and for this reason there is currently much interest in finding high-bit-rate solutions. ADSL is seen as a cost effective method of providing entertainment quality uni-directional video on demand, over the twisted pairs of the existing telepho... View full abstract»

    The recent announcement of carrierless amplitude and phase modulation technology show promise that this will become the most efficient method of transmitting data and digitised video at T1 and El rates over the existing subscriber loop infrastructure, now referred to as HDSL and ADSL. In this article an attempt has been made to describe this new concept and to list its advantages. View full abstract»

    We present various aspects of a high performance ADSL transceiver system using the powerful discrete multitone (DMT) modulation technology. DMT is the adopted ADSL line code for the emerging North American (ANSI), as well as the European (ETSI), ADSL standard. We first introduce the basic concept of DMT modulation, which effectively divides the transmission channel into a number of parallel subcha... View full abstract»

    This paper is concerned with ADSL systems operating in BT's local access network-exploiting the existing metallic wires which connect peoples' houses to telephone exchanges. We consider the performance consequences of various architectural options. Generally the options are to give more service, but require the transmission system to carry more payload-so the transmission system loses reach: enhan... View full abstract»

    There are many emerging technologies, allowing an increase in the bandwidth of access network, but their deployment has been minimal due to their high cost for no additional operator revenue. So for the majority of residential customers their link to the Information Superhighway continues to consist of a single twisted copper pair telephone line. This paper argues that: the development of the resi... View full abstract»

    Some of the requirements and drivers for video on demand (VoD) servers are presented in the context of a networked system. The storage capacity, the standard delivery format, hybrid servers, and the delivery system hierarchies are discussed. The major design requirements identified are summarized by considering the following: the user interface constraints; the functionality required of the VoD se... View full abstract»

    After an overview of broadcasters' requirement for video recorder and player, the new optical disc format which is under development by Pioneer is introduced. This format opens up a major application area: "near video on demand play-out". Total system concept of this application is explained briefly. View full abstract»

    The author discusses BT's video-on-demand technology trial; a trial which set out to answer the technical issues surrounding the viability of a number of technologies key to the development of interactive multimedia services. The trial is based in Kesgrave, with a video server comprising an nCube parallel processing computer playing video stored on a magnetic disk store. The value of the parallel ... View full abstract»

  • Payment-the key enabler for superhighway services

    Initial discussion, comments and "hype" about the information superhighway-or as we Europeans call it, the "infobahn"-has tended to focus on the highway as a means for delivering services (such as 500 channel television or telephony) rather than as a medium for business. In recent times, however, the more commercial aspects have been explored and a new view of the infobahn is emerging-the "downloa... View full abstract»
