Suggested viewport instructions for panoramic video

摘要

PROBLEM TO BE SOLVED: To provide an encoder and a method for outputting a proposed viewport instruction for a panoramic video. Proposed viewport instructions are generated and transmitted for use in panoramic video. In one example, the methods are to receive an encoded video containing viewport metadata, to decrypt the video, to retrieve the viewport metadata, and to viewport the viewport of the decrypted video. Includes generating based on metadata and buffering the generated viewports for display. [Selection diagram] Fig. 2
