THE PATENTS ACT 1990 The invention comprises the use of a community communications facility that minimises the need for individual consumer equipment that in the case of antennas of the dish variety, make unsightly appendages to residential or commercial properties, and in the case of electronics for receipt and transmission of video and audio services, encryption, decoding, compression, digitising, and other high technology transmission related activities, such are expensive and often impractical if the transmissions being received are too weak from distant sources, or if terrestrial, are shaded by buidings or terrain features, from the equipment of the end user. The high cost of trunk coaxial or fibreoptic cabling, shortage of radio spectrum, and cost of satellites capable of transmission direct to consumers and receivable on small dishes, makes the concept of community antenna and communications facilities desirable for use with short range consumer transmission and reception equipment particularly of the type appropriate to microcellular radio telephony and interactive TV transmissions. The combined use of radio and cable transmissions over short distances to and from the premises of end users, and thence from the community transmission facility to hilltop retransmission facilities or direct to satellite; offers flexibility and economy, and has benefits in respect to copyright laws where receipt of long range broadcast transmissions by viewers and listeners would otherwise be a breach of copyright laws. |
