5.2 Notes on using MPEG window

(1) MPEG window display switch 

 The following restrictions apply to the MPEG window display switch.
(a) Two or more VDP2 output window display switches must not be turned ON simultaneously.
Please connect and use as shown below.

(2) Host transfer output

When the image is transferred to the host, the number of pixels in the X direction is twice as large as the frame buffer window size due to the MPEG system specifications. To avoid this, it is necessary to set the display size to half and the magnification to double in the X direction as shown in the example below. 

 / * Host transfer output of 352 x 240 pixel image at the same magnification * /
     / * Change display size * /
     MPG_WnSetSize(mpgwn, (352/2), 240);

     / * Set magnification * /
     MPG_WnSetDispRatio(mpgwn, 2000, 1000);

     / * Host transfer output execution * /
