Abstract:
Function extender devices for enhancing feature sets for display arrangements having source devices and sink devices are disclosed. In one embodiment, a non-addressable device is disclosed for use in a system having a source and a sink to communicate with each other via a bus, where the non-addressable device comprises a functional logic block for coupling between the source and the sink and operable to perform at least one function on data of one or both of the first channel for video and audio data or data of a sideband channel received from the source, where the data of the first channel for video and audio data and data of a sideband channel are received from the source being addressed to the sink. The device also comprises a Physical (PHY) repeater operable to transmit data of both the first channel and the sideband channel after performance of the at least one function by the functional logic block on the data of one or both of the first channel or the sideband channel received from the source.
