Hi, The values originate from the spruf73a.pdf document that came with the updated LSP.
It provides 3x D1 PAL buffers (720x576) not very exactly. An exact fit would be 2430K, which is (720x576x2x3)/1024. We have used configurations with 10 buffers of NTSC, so it then becomes 720x480x2x10/1024 = 6750K. Being lazy it means that NTSC & VGA will fit ;-) Regards Phil Q Phil Quiney, Senior Software Engineer Trinity Convergence Cambridge Business Park Cowley Road Cambridge CB4 0WZ, UK T: +44(0)1223-435536 F: +44(0)1223-435560 www.trinityconvergence.com -----Original Message----- From: Jaswinder Singh [mailto:[EMAIL PROTECTED] Sent: 17 September 2008 11:03 To: Phil Quiney Cc: amingaming; [email protected] Subject: RE: about LCD?

But DVEVM Demos (decode, encode and encodedecode) only supports NTSC and PAL. How can we supports VGA LCD and and other resolutions in DVEVM demos. Are you able to play DVEVM demos by using VGA LCD ? Thank you, Jaswinder Singh. _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
