ABSTRACT:
A method consistent with certain embodiments, of processing a received encrypted frame signal, wherein the received encrypted frame signal is indicative that a specific video frame is encrypted, involves receiving a video signal including the received encrypted frame signal; wherein the received video signal comprises a received bit stream; synthesizing the received encrypted frame signal to produce a synthesized encrypted frame signal that is in synchronization with the received encrypted frame signal; determining if a sink wireless receiver is locked to the received bit stream, and if so, passing the received encrypted frame signal to the sink device; and if the sink wireless receiver is not locked to the received bit stream, passing the synthesized encrypted frame signal to the sink device. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
