Dolby Vision is built into the panel....not the STB.
No, Dolby Vision is built into everything. In Dolby's phraseology, it is an end-to-end project for greater visual fidelity, requiring of panels greater color depth, wider gamut, and higher brightness. It requires new processing methods and standards in the movie-making business (it has sponsered the first Dolby Vision movie master of the movie Chicago), new equipment in theaters, new broadcast TV methods for the extra information about brightness and color, new set top boxes to get the enhanced video signals to users' TVs, new blu-ray specs to record the enhanced signals.
Dolby Vision is a big, big project. Google "Dolby Vision".
