Does VENC support square pixel mode?

Hi,

     I am reading  datasheet  of DM365. VENC in DM365 operate at 27MHz and support resolution 720*576. But in my application, square pixel mode is required (768*576 pixels per frame, PAL composite output). Does VENC support square pixel mode? Any register should be changed?

   Thanks!

    I am assuming you mean that you have a 768x576 source image in memory that you need to display on the VPBE?

    The VPBE has built in resizing to take 640x480 content and fill it to either a NTSC 720x480 display or a PAL 720x576 display with a proper 4:3 aspect ratio as discussed in chapter 4.4.2.5.2 of SPRUFG9, however it does not have any direct way of managing a 768x576 digital image to display. To handle this you would have to do a horizontal resize from 768 to 720 before passing the frame into the VPBE to be displayed, this could be handled in software or through the hardware IPIPE resizer built into the VPFE.
