Techniques for enabling the display of video content is a specified display mode, such as the Ultra-High Definition Alliance Specified Reference Mode (UHDA-SRM). A video source device receives video content as a bitstream in one format that includes a specification of a display mode for the video content. The video source also receives information from a display device or other video sink on the display modes that it supports. If the display device supports the specified display mode, the video provides the video content to the display in a second format, such as HDMI, as a series of frames the specification of the display mode embedded in a blanking interval in each of the frames.

An apparatus for use in a high-definition media interface (HDMI) source device includes an HDMI interface for transmitting video data and metadata to a sink device. The apparatus is configured to encode the metadata in an auxiliary video information (AVI) information frame (InfoFrame). The apparatus is further configured to transmit the AVI InfoFrame during a frame synchronous transmission window (FSTW) of the video data, wherein the FSTW begins during a video blanking interval (VBI) of the video data, on a first video blank pixel that immediately follows a last active video pixel of a preceding video frame or video field and ends a predetermined number of video lines after a start of the VBI.
