Patent ID: 8671234

Claim:
An adaptor that enables data transmission from a dual-mode source device having a first primary data format to a sink device configured to receive a dissimilar second data format, the adaptor comprising: a source format detector module that enables the adaptor to identify whether a dual-mode source device coupled with the adaptor provides multimedia data in a second mode or a third mode; a main link level shifting module for converting a second mode main link signal and a third mode main link signal from an AC-coupled main link signal to a DC-coupled main link signal; a second sideband signal processing module configured to process an AC-coupled second mode side band signal that includes a clock signal and a data signal by level shifting the second mode sideband signal to generate a DC-coupled sideband signal with the clock signal and data signal for output to the sink device; and a third sideband signal processing module configured to process an AC-coupled third mode sideband signal comprising a packetized data signal with embedded clock by converting the third mode sideband signal to a DC-coupled sideband signal with the clock signal and data signal for output to the sink device.
