Hi, Harikrishnan P, Yeah, you are right. A standard PC graphics card has only one Layer, but sophisticated devices like TV set top boxes may support two or more layers. That depends on the graphics hardware. Today, most PC graphics cards also support an additional layer (a ”‘video layer”’), which can be scaled and does color conversion from YUV to RGB. This layer cannot usually be blended and has to remain fully opaque. Video layers are supported by varios DirectFB graphics drivers.
And I got some information from http://www.intel.com/design/intarch/swsup/graphics_faq.htm it said like this: ///////////////////////////////////////////////////// Second Overlay �C Supported platforms: 852, 855, 910, 915, & 945 ///////////////////////////////////////////////////// Best regards, chiachen [EMAIL PROTECTED] 2008-06-03 ======= 2008-05-21 13:39, your message: RE: [directfb-dev] How to get the Intel 852/855 overlay======= hi chiachen, A PC is having only one layer according to my understanding. So what ever you have got is correct I think.Can you please tell me from where the other person got the information ?
