VIP core - Frame Reader (On Screen Display)

[Altera_Forum]

Hi all - how would I display a 'picture' , for example a bitmap, on the on-screen display. 

I'm working through a design example on the NEEK - the author has gone to some trouble to write some routines for a reasonably comprehensive OSD , including text/fonts on the OSD.  Lurking in the code is a folder refering to The Gimp and bitmaps with what looks like some conversion routines. In the design example the OSD is simply a block of allocated memory storing pixel data - is it just a case of copying the (converted?) bitmap to this memory?  I'm a little new to the VIP - any help would be appreciated, cheers, JB.

The basic idea is like this 

1. put the bitmap data on off-chip-mem(if it very small, then you could use onchipmem) 2. read the picture data by using frame reader 3. send the data to mixer as a layer (cause you might want to change picture) 4. send the data to clocked video output
