Abstract
Abstract A network which is suitable for the distribution of signals such as video and audio is disclosed. A second network is overlaid on an existing LAN to provide audio and video functionality, without further loading the capacity of the LAN. Switching of the video and audio signals is provided by a switchbox, controllable from the LAN via the server. The second network may be a simple UTP arrangement.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A system providing selective distribution within a network including a plurality of user terminals of video and/or audio data, control signals for said video and/or audio data, and further data, characterised in that the further data and control signals are carried on a first digital network, and the video and/or audio data is transmitted over a second, physically distinct analog cable network, said terminals being connected to both the first and second networks, said second network being responsive to said control signals via switching nodes communicating with both networks, said switching nodes being shared on the second network and not being associated with individual ones of said user terminals.
Claim 2
Independent Claim
109 words
A system providing selective distribution within a network including a plurality of user terminals of video and/or audio data, control signals for said video and/or audio data, and further data, characterised in that the further data and control signals are carried on a first digital network, and the video and/or audio data is transmitted over a second, physically distinct analog cable network, said terminals being connected to both the first and second networks, said second network being responsive to said control signals via switching nodes communicating with both networks, said switching nodes being shared on the second network and not being associated with individual ones of said user terminals.
Claim 3
Dependent Claim
19 words
A system according to claim 1, wherein said second network comprises a series of unshielded twisted pair (UTP) connections.
Claim 4
Dependent Claim
18 words
A system according to claim 1, wherein each user terminal uses a discrete connection to the switching node.
Claim 5
Dependent Claim
30 words
A system according to claim 1, wherein said second network includes sources of analog video signals, said sources being arranged so that their signals are switched via said switching nodes.
Claim 6
Dependent Claim
35 words
A system according to claim 1, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 7
Dependent Claim
18 words
A system according to claim 2, wherein each user terminal uses a discrete connection to the switching node.
Claim 8
Dependent Claim
30 words
A system according to claim 2, wherein said second network includes sources of analog video signals, said sources being arranged so that their signals are switched via said switching nodes.
Claim 9
Dependent Claim
30 words
A system according to claim 3, wherein said second network includes sources of analog video signals, said sources being arranged so that their signals are switched via said switching nodes.
Claim 10
Dependent Claim
30 words
A system according to claim 6, wherein said second network includes sources of analog video signals, said sources being arranged so that their signals are switched via said switching nodes.
Claim 11
Dependent Claim
35 words
A system according to claim 2, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 12
Dependent Claim
35 words
A system according to claim 3, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 13
Dependent Claim
35 words
A system according to claim 4, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 14
Dependent Claim
35 words
A system according to claim 6, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 15
Dependent Claim
35 words
A system according to claim 7, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 16
Dependent Claim
35 words
A system according to claim 8, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
Claim 17
Dependent Claim
35 words
A system according to claim 9, wherein at least one switching means is provided within said second network, such that said switching means responds directly or indirectly to control signals sent over said first network.
