An assessment of the potential of new markets and business opportunities arising from Digital Technology by Colin J. Knowles of the Australian Broadcasting Authority
We live in a world where new opportunities are continually opening, new businesses form to exploit these opportunities and old businesses must adapt or become extinct. Occasionally, radically new knowledge is created which results in a quantum shift in fundamental thinking and technology, which rapidly moves our endeavors to a new plane of activity. Digital signal processing is one of those changes. It has been the catalyst to the convergence of most forms of information dissemination: content creation, production and publishing, newspapers, broadcasting and telecommunications. Digital technology has brought us to the point where there will be few constraints on our capacity to deliver information and entertainment to consumers and the number and types of services available will be determined by commercial returns on investment rather than by channel capacity. Services will be delivered using digital transmission via a variety of means; Satellite, Free-to-Air terrestrial Broadcast in the VHP and UHF Bands, MMDS, and Cable and over time these transmission methods will become more and more specialised and adapted to the types of service delivery for which they are the most efficient. For example, a major sporting event with national interest might be transmitted via satellite, whereas a return of yesterday’s news or a personally selected documentary would be delivered via cable.
