Abstract

The invention relates to a mapping method and device of color spaces. The method comprises: coding an obtained first video to obtain a first YUV coded format video; mapping the first color space of the first YUV coded format video to a second color space to obtain a second YUV coded format video. Through the technical solution, the obtained first video is coded to obtain the first YUV coded format video; the first color space of the first YUV coded format video is mapped to the second color space to obtain the second YUV coded format video, therefore the video can be normally played by other video play devices.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a color space mapping method and device. Background technique [0002] In the related art, the television playback device can receive video from the Internet and play it, but after decoding the video received from the Internet, a color space of YUVJ420P is obtained. However, the color space generally required by video playback devices is YUV420P, without J. Color space YUVJ420P, its color value is the same as that of the computer, 0-255, suitable for digital signals. But the color space YUV420P is a TV value, 16-240, suitable for analog signals. Both color spaces are offshoots of i420. 420 refers to 4-digit Y, 1-digit U, and 1-digit V. If the color of the video falls within 0-15 or 241-255, that color value is invalid for the TV, so the TV signal cannot be transmitted. Contents of the invention [0003] Embodiments of the present invention provide a color ...
