NETWORK FOR MULTIMEDIA ASYNCHRONOUS TRANSFER MODE DIGITAL SIGNAL TRANSMISSION AND COMPONENTS THEREOF |
摘要 |
Apparatus and methods for transmitting digital multimedia signals in asynchronous transfer mode over unshielded twisted pair wiring in a multipoint topology in an improved cost-effective manner. The multimedia digital signals originate from and are received by a plurality of receiving stations connected via twisted pair wiring. The method comprises feeding input digital signals selected from the group consisting of voice, fax, video and data from signal nodes; controlling allocation of bandwidth to the input digital signals as between sending stations; providing a source data stream in binary format derived from allocated input digital signals; converting a source data stream into a digital symbol stream capable of being transmitted over the wiring; driving and filtering the digital symbol stream over the wiring; splitting the filtered digital symbol stream into a plurality of replicated digital symbol streams; amplifying and selecting each of the plurality of replicated digital symbol streams to provide an amplified and selected digital symbol stream; converting the amplified and selected digital symbol stream into a sink data stream in binary format; identifying and selecting desired digital signals of the sink data stream for the plurality of the receiving stations; and delivering the identified and selected digital signals to signal nodes.
