48-bit High Precision and Wide Gamut Format  
The 48-bit High Precision and Gamut Format is an scRGB color space using the same primaries and white points as sRGB. It includes support for all applications including imaging, video, web authoring, and gaming applications. It also provides support for HDR monitors.  
Bit Depth Comparison  
The following sections list the key benefits of this format and their relevance to application developers.  
8-bit per channel sRGB  
· Not enough precision/image quality for professional and pro-sumer applications  
· Does not cover gamut of current cameras (e.g., Adobe RGB) or upcoming media formats  
· Does not cover gamut of current and upcoming monitors and TVs  
· Provides efficient bandwidth/power consumption such as required for laptop form factors  
· Current standard on all PCs, GPUs, and monitors  
10-bit per channel sRGB (high precision)  
· Enough precision/image quality for medical and technical applications  
· Does not cover gamut of current cameras (e.g., Adobe RGB) or upcoming media formats  
· Does not cover gamut of current and upcoming monitors and TVs  
· Efficient bandwidth/power consumption such as required for laptop form factors  
· Trivial implementation even on most DX9 GPUs  
10-bit per channel xRGB (extended range)  
· May not have enough precision/image quality for professional and pro-sumer applications  
· Covers gamut requirements for current cameras and upcoming media formats  
· Covers gamut of current and upcoming monitors and TVs  
· Efficient bandwidth/power consumption such as required for laptop form factors  
· New implementation; no support for transparent compositing in GPUs today  
16-bit per channel scRGB (high precision and wide gamut)  
· Covers all gamut requirements for all future media  
· Trivial implementation even on most DX9 GPUs  
· 2x bandwidth and power consumption versus other formats  
· Enables HDR (high dynamic range) displays  
 The following information outlines support and color specifications of the new pixel formats.  
· All of the new formats use the same primaries and white points (CCIR 709).  
· Integer formats are gamma corrected to 2.2 as per the sRGB spec. Float formats are linear as in the scRGB spec.  
· All of the new formats are supported on GPUs that have shipped since 2004.
