3D MODE SELECTION MECHANISM FOR VIDEO PLAYBACK Russian patent published in 2014 - IPC H04N13/00 G11B27/32 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a method of playing back video information which is suitable for both two-dimensional (2D) display and three-dimensional (3D) display. The technical result is achieved due to that the video information and associated playback information are organised according to a playback format. The video information comprises a primary video stream for 2D display, and an additional information stream for enabling 3D display, wherein that the associated playback information comprises display information indicating the types of display possible. The method involves processing the display information to determine that both 2D display and 3D display are possible for the received video information; determining a playback setting of a playback device indicating whether the video information should be displayed in 2D or 3D; and processing for display either the primary video stream or the primary video stream and the additional information stream, in accordance with the playback setting of the playback device.

EFFECT: easy switching of 2D and 3D content depending on both viewing conditions and the number of users viewing the display at the same time, or preferences thereof.
