![]() ![]() The 10-bit formats also use 16 bits for each channel, with the lowest 6 bits set to zero, as shown in the following diagram.īecause the 10-bit and 16-bit representations of the same YUV format have the same memory layout, it is possible to cast a 10-bit representation to a 16-representation with no loss of precision. ![]() The 16-bit representations described here use little-endian WORD values for each channel. For example, if the white point of an 8-bit format is 235, the corresponding 10-bit format has a white point at 940 (235 × 4). Precision conversions can be performed using simple bit shifts. Sample values are scaled 8-bit values, using a scaling factor of 2^(n − 8), where n is either 10 or 16, as per sections 7.7-7.8 and 7.11-7.12 of SMPTE 274M. These formats use a fixed-point representation for both the luma channel and the chroma (C'b and C'r) channels. This topic contains the following sections: This topic describes the 10- and 16-bit YUV formats that are recommended for capturing, processing, and displaying video in the Microsoft Windows operating system.
