Data flow from SHR camera to SHR projector without and with video shift and
padding function
copy the top and bottom lines of image data onto non-image data areas. There is an
example of a data flow that includes the video shift padding function in Fig. 4 (b).
A data flow without the function is also shown in Fig. 4 (a). In both examples, the
1920 x 2060 pixel images of the SHR camera are output using two 1035-HDSDI
