Abstract
Methods, systems and apparatuses are described to detect and resolve device configuration and/or communication incompatibilities (e.g. incompatible messages, improper addressing, malfunctions) for a communication protocol such as HDMI-CEC.
Claims20
A device configured to selectively modify:
- (i) a communication path coupled to a sink device and a plurality of source devices and (ii) a communication message from the sink device or a source device among the plurality of source devices.
A compatibility device configured to (i) detect an incompatibility between a plurality of communication devices including a plurality of source devices that send source communication messages and a sink device that sends sink communication messages and (ii) block, modify or replace a sink or source message to or from a device among the plurality of communication devices causing the incompatibility.
A method, comprising:
- monitoring a plurality of source devices configured to be coupled to and decoupled from a sink device;
- determining that at least one of the plurality of source devices is incompatible;
- and
- blocking a message from the at least one incompatible source device while not blocking a compatible message from at least one of the plurality of source devices.
