An introduction to worldwide multimedia teleconferencing and video server standards

1 : Introduction

MPEG-1 is actually inadequate because it does not contain timing information to regulate frame rate. A consortium of 85 European companies also signed an agreement in 1993 to fund a video broadcasting project using MPEG-2.

  • Highlights of advertisements may be screened on regular media as they are currently;
  • ATM is ideal for its high bitrate;
  • Illegal video shops could flourish when it becomes much easier for them to obtain movies, and sell these to residents not willing to pay for overheads of installing VoD;
  • Viewers also show strong habits of watching a "strip" of programs and flipping through channels.

A major problem in implementing the transmission protocols is the limitation of bandwidth of the medium. As it will be several years before fibre is laid to the home, protocols have to run over twisted copper or in the urban areas, co-axial cable.

ATM is ideal for its high bitrate.

A shortfall for linking ATM all the way to the home is the enormous cost of the equipment and the sheer size currently the size of a medium TV. This makes ATM an unfeasible solution for the time being.

  1. Video on Demand is an important aspect of this interactive media technology that is currently conquering the information systems worldwide. MPEG has conquered huge grounds as far as standards go and make great efforts to ensure that they remain as international standards for moving picture coding.
  2. Video on Demand is an important aspect of this interactive media technology that is currently conquering the information systems worldwide. Conclusion The presence of potential technologies for audiovisual information transmission, encoding and storage has made transition to interactive media systems almost inevitable, justifying the criticism that "Interactive Multi-Media is a technology looking for applications".
  3. Issues on Copyright Copyrights and piracy may prove to be something difficult to enforce once VoD is born.
  4. Consequently, VoD applications need well structured indexes and user friendly menus for quick browsing.

Developments, Concerns and Fears The quest towards interactivity has already taken initiative in many countries. Such products have a great potential to make fully operational IMMSs a reality in the near future.

Video on Demand

Role of Advertising Broadcasting companies get the bulk of income from advertisers. No doubt that the VoD system coming will still contain advertisement of some kind, possibly interactive. Highlights of advertisements may be screened on regular media as they are currently. Issues on Copyright Copyrights and piracy may prove to be something difficult to enforce once VoD is born.

  • MPEG has conquered huge grounds as far as standards go and make great efforts to ensure that they remain as international standards for moving picture coding;
  • There is little doubt that people will record movies using home VCRs and lend them to friend or neighbours;

There is little doubt that people will record movies using home VCRs and lend them to friend or neighbours. Illegal video shops could flourish when it becomes much easier for them to obtain movies, and sell these to residents not willing to pay for overheads of installing VoD.

The boundaries of many of the current forms of information services and media will soon get blurred away, when the discrimination of the Television and a "Home shopping channel" would be somewhat analogous to the difference between radio FM and AM taday.

Video on Demand is an important aspect of this interactive media technology that is currently conquering the information systems worldwide.

MPEG has conquered huge grounds as far as standards go and make great efforts to ensure that they remain as international standards for moving picture coding. Much work is ongoing, and we should expect to see results within the next two years!
