An interface adapter converts a video signal compliant with multiple video transmission interface specifications to a video signal compliant with a HDMI specification for display upon a video display. The interface adapter has a plurality of input ports to receive the video signals. The interface adapter further has a source selector to select one of the input ports to provide the video signal. A synchronization device receives and retains the selected video signal based on timing signals of video signal's transmission interface specification. A high definition multimedia formatter extracts the video signal with a timing signal in compliance with the HDMI specification, formats the video signal to the voltage levels and format of the HDMI. A transition minimized differential signaling driver amplifies and buffers the video signal in compliance with the HDMI specification for transfer through the output port to a video display.
