+       -  Digital video encoder. The basic function of the video encoder is
+         to accept digital video from some digital video standard with
+         appropriate timing signals (usually a parallel video bus with sync
+         signals) and output this to a digital video output connector such
+         as HDMI or DisplayPort.
