5.1.2. Video Geometry Measurement Path

The video geometry measurement path determines the video geometry (such as HTOTAL, VTOTAL, and VHEIGHT) required for the DisplayPort main stream attributes (MSA), which are sent once every vertical blanking interval.

The MSA generator provides the MSA packet framed with secondary start (SS) and secondary end (SE) comma codes based on the requested lane count. The multiplexer then combines the packetized data from the video packetizer path and the MSA data into a single stream.
