MOVING IMAGE DISTRIBUTION SERVER, MOVING IMAGE REPRODUCTION APPARATUS, CONTROL METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

A moving image distribution server renders a distribution screen by rendering processing in at least two stages using viewpoint information to determine the screen to be rendered. The rendering processing is performed such that the distribution screen is rendered in rendering processing of the subsequent stage by referring to a Depth map generated by rendering processing of the preceding stage. The moving image distribution server selects the Depth map for coding determination during execution of rendering processing of the subsequent stage for the first screen, and determines for each set block whether to perform inter-frame coding by referring to a Depth map generated for a second screen rendered before the first screen. After rendering processing of the subsequent stage has ended for the first screen, the moving image distribution server performs coding in accordance with the determination result and sends the coded moving image data to an external device. The determination result is sent to the external device before generation of the coded moving image data of the first screen is completed.
