Dynamic Control of Pixel Color Formats Used to Encode Color Video Streams

摘要

Embodiments of the present disclosure are related to dynamic control of pixel color formats. In one embodiment, more than one pixel color format is used to encode a single scene within a video stream. This may be done for various reasons. For example, the available transmission bandwidth may change, thus leading to a change in the pixel color format where the new pixel color format uses a different amount of transmission bandwidth. Alternately, different regions within a scene may be encoded using different pixel color formats due to differences in their content. A highly detailed, vibrantly color region may be encoded using a richer color space and more bits per pixel, while a flat monotone region may be encoded using a pixel color format with fewer bits per pixel.

主权项

1. A method for transmitting color video streams from a source to a sink, the method comprising:
transmitting, from the source to the sink, a plurality of color pixels; the color video streams comprising video scenes, each video scene comprising video frames, and the video frames comprising the transmitted color pixels; and transmitting, from the source to the sink, data indicating the pixel color formats used to encode the transmitted color pixels, at least one of the video scenes encoded using two different pixel color formats.
