Abstract

Описываются способы, чтобы сообщать информацию об исходном цветовом объеме в кодированном битовом потоке с использованием обмена сообщениями SEI. Такие данные включают в себя, по меньшей мере, значения минимальной, максимальной и средней яркости в исходных данных плюс опциональные данные, которые могут включать x и y координаты цветности цветового объема для входных основных цветов (например, красного, зеленого и синего) у исходных данных, и x и y координаты цветности цвета для основных цветов, соответствующих значениям минимальной, средней и максимальной яркости в исходных данных. Также могут быть включены данные обмена сообщениями, сигнализирующие активную область в каждой картинке.Techniques are described to report source color volume information in an encoded bitstream using SEI messaging. Such data includes at least the minimum, maximum, and average luminance values in the source data, plus optional data, which may include the x and y chromaticity coordinates of the color volume for the input primary colors (e.g., red, green, and blue) of the source data. , and x and y are the color chromaticity coordinates for the primary colors corresponding to the minimum, average, and maximum brightness values in the source data. Messaging data signaling the active area in each picture may also be included.
