摘要

PROBLEM TO BE SOLVED: To provide a moving image coding method for preventing interruption during playback without increasing the processing load during playback.

SOLUTION: The moving image encoding method for encoding a video stream containing a first moving image and a second moving image to be overlaid the first moving image. The method includes: steps (S5301 to S5303) for deciding a continuous playback section which is a set of partial sections in a video stream to be continuously reproduced; a step (S5304) for encoding the first and the second moving image in the partial sections constituting the continuous playback section so that the threshold value to be used for a transparency process by a luminance key in the overlay is not modified; and a step (S5305) for creating management information containing flag information indicating that the threshold value is fixed in the continuous playback section, and information indicating the threshold.
