METHOD TO CODE MOVING IMAGE, DEVICE TO CODE MOVING IMAGE, METHOD TO RECORD MOVING IMAGE, RECORD MEDIUM, METHOD TO REPRODUCE MOVING IMAGE, DEVICE TO REPRODUCE MOVING IMAGE, AND SYSTEM TO REPRODUCE MOVING IMAGE Russian patent published in 2013 - IPC H04N7/26 H04N5/92 G11B27/28 

FIELD: radio engineering, communication.

SUBSTANCE: method to code a moving image codes a video stream containing the first dynamic image and the second dynamic image for superimposition onto the first dynamic image. The method includes the following: stages (S5301-S5303) to detect a section of continuous reproduction, which is a group of partial sections and is exposed to continuous reproduction; a stage (S5304) to code the first and second dynamic image in partial sections, making a section of continuous reproduction, in order to satisfy a limitation that a threshold value used for processing of transparency by means of a brightness key in superimposition, does not change: and a stage (S5305) to develop control information containing flag information, indicating that the threshold value is fixed in the section of continuous reproduction.

EFFECT: provision of a record medium, a method to code a moving image, which may suppress heterogeneity of reproduction without increase of processing load during reproduction.
