Patent ID: 8922578

Claim:
A device for embedding alpha red green blue (ARGB) data in an RGB stream comprising: a memory for storing instructions and one or more lookup tables; a processor for executing an application, wherein said application renders data into an ARGB texture; a graphics card which draws said ARGB texture on a screen and then processes said ARGB texture; a first video output interface for transmitting said processed ARGB texture; and a mixer device, wherein said mixer device comprises: two or more interfaces for receiving said processed ARGB texture and at least one other video signal; a processor for executing instructions for processing said received processed ARGB textures such that said received processed ARGB texture is combined with said at least one other video signal resulting in a composite signal; and a second video output for transmitting said composite signal, wherein said one or more lookup tables includes a first look up table for said graphic card's gamma correction, a second lookup table for mapping between pre and post gamma corrected spaces, a third lookup table for mapping corrected gamma values into integer values and a fourth lookup table for allowing said mixer device to undo a gamma correction when processing said processed ARGB texture.
