Control data packets configure the MegaCore functions so that they correctly process
the video data packets that follow.
In addition to a packet type identifier of value 15, control data packets contain the
following data:
The width and height values are the dimensions of the video data packets that follow.
The width refers to the width in pixels of the lines of a frame. The height refers the
number of lines in a frame or field, such that a field of interlaced 1920×1080 (1080i)
would have a width of 1920 and a height of 540, and a frame of 1920×1080 (1080p)
would have a width of 1920 and a height of 1080.
