Abstract
A method and system for selecting a signal from a plurality of signals received by a component in an AV system. An identifier is added (106) to a signal in dependence on the signal being generated by an active component of the system. For each received signal containing an identifier, one or more parameters of the identifier are determined (116), such as the start time when the component became active, or the address of the component. A signal is selected (124) from the plurality of signals received according to the determined parameters and optionally with reference to a relevant parameter such as component address sent via a separate communications channel.
Claims25
A method for selecting a signal from a plurality of signals received by a component in an AV system comprising:
- adding (106) an identifier to a signal in dependence on the signal being generated by an active first component;
- sending (108) the signal from the active first component;
- receiving (110) a plurality of signals at a second component;
- for each signal of the plurality of received signals:
- analysing (112) the signal for the presence of the identifier;
- and
- where the identifier is present determining (116) and storing at least one parameter associated with the identifier;
- and
- selecting (124) a signal from the plurality of received signals in dependence on stored ones of the parameters.
An AV system comprising at least a first component (202, 204) connected to a second component (206) by a connection means, wherein the first component is operable to:
- add an identifier to a signal in dependence on the first component being active;
- send the signal to the second component;
- and wherein the second component is operable to:
- receive from at least one first component a plurality of signals;
- for each signal of the plurality of received signals:
- analyse the signal for the presence of the identifier;
- and
- where the identifier is present determine and store at least one parameter associated with the identifier;
- and
- select a signal from the plurality of received signals in dependence on stored ones of the parameters.
