HDB-MAC A New Proposal for High Definition TV Transmission

During the last few years there has been increasing interest in the use of high-definition television (RDTV) equipment to reduce costs in programme production. It is also clear that the wider aspect-ratio of HDTV, and the absence of picture impairments, would be very attractive to many consumers if delivered at the right price. In fact, it is not unreasonable to suggest that a successful system for the delivery of HDTV to the public could both differentiate and enhance the value-of the programming supplied, and give rise to the next generation of consumer TV sets. Moreover, the opportunity for HDTV distribution extends beyond broadcast and cable technologies to VCR tape and video disc. Therefore the possibility exists that these distribution industries might be bypassed unless a practical HDTV signal format is devised.
