B-MAC — A Transmission Standard for PAY DBS

The signals in use today for the transmission of broadcast TV services are direct descendents of the original monochrome transmissions of the 1940s. The method adopted for the addition of colour (namely the colour subcarrier) was dictated by the requirement to be compatible with the early monochrome receivers, and by the technology then available. Since that time, there have been significant advances in technology, due in particular to the advent of large scale integration of electronic components. Moreover, the economic environment in which television services must operate has been transformed through the introduction of Cable TV, VCRs, video games, home computers, etc. which compete for the screen. (It is forseeable that the home TV receiver may degenerate into a monitor, fed by a series of stand-alone input devices, each providing a separate service).
