Abstract
A video data processing method and/device for display adaptive video playback are disclosed. The video data processing method includes receiving video data and dynamic range mastering information including dynamic range related information of the video data from a source device via an interface, and playing the received video data back. The dynamic range mastering information includes electro optical transfer function, EOTF, type information for identifying an EOTF used for the video data.
Claims15
