Abstract
A method and system for switching signals over conductors is disclosed. The method and system comprises a plurality of encoders for receiving signals from a plurality of sources. The system further comprises a crosspoint switching matrix means for receiving encoded signals from the plurality of encoders and for providing encoded signals to a plurality of receivers. The crosspoint switching matrix means in a preferred embodiment includes a control system which is controlled by multiple remote receivers.
Claims11
A system adapted for switching over conductors capable of including an unshielded cable including a twisted pair cable, signals received by the system from a plurality of audio/video sources, the system comprising:
- a plurality of encoders each of which is adapted for concurrently receiving a plurality of baseband signals from specific sources included among the plurality of sources and for producing from the received signals a single encoded signal;
- and
- a crosspoint switching matrix means adapted for concurrently receiving encoded signals from each of the plurality of encoders and for concurrently providing signals received from the encoders to a plurality of receivers;
- wherein the plurality of encoders are directly coupled to the crosspoint switching matrix;
- and
- wherein the crosspoint switching matrix is coupled directly to the conductors, and the conductors are external to the system.
An electronic switching system adapted for switching over conductors capable of including an unshielded cable including a twisted pair cable, signals received by the electronic switching system from a plurality of audio/video sources, the electronic switching system comprising:
- a plurality of encoders each of which is adapted for concurrently receiving a plurality of baseband signals from specific sources included among the plurality of sources and for producing from the received signals a single encoded signal;
- a crosspoint switching matrix adapted for concurrently receiving encoded signals from each of the plurality of encoders and for concurrently providing signals received from the encoders to a plurality of receivers;
- and
- a control system coupled to the crosspoint switching matrix, the control system routing control signals from a remote control input to a source,
- wherein the control signals travel from the remote control input in a direction opposite to a direction in which encoded signals travel from the crosspoint switching matrix to receivers;
- wherein the conductors are external to the electronic switching system;
- and
- wherein the plurality of encoders are directly coupled to the crosspoint switching matrix and the crosspoint switching matrix is coupled directly to the conductors.
