Abstract
An HDMI transmitter inserts an additional video line in the video frame to be transmitted via the HDMI interface and inserts auxiliary data related to the video frame in the additional video line. The auxiliary data is related to the video frame and as the auxiliary data is stored in the video frame itself it is transported in a synchronous fashion with the video frame. As the additional video line is in excess to the number of video lines defined by a standard video frame format they are ignored by existing receivers yet available to receivers according to the invention and can be transmitted using the existing HDMI standard.
