VIDEO ENCODER, PREDECODING METHOD, VIDEO DECODING METHOD, DEVICES THEREFOR, AND IMAGE FILTERING METHOD, FOR VIDEO STREAMING SERVICES

摘要

PPROBLEM TO BE SOLVED: To provide a video encoder, a predecoding method, a video decoding method, and devices therefor, for a video streaming service having high definition and high video coding efficiency. PSOLUTION: A video encoder includes a video encoding section and a super bitstream generating section. The video encoding section performs video encoding on each of a first video sequence and second to nth video sequences that differ from the first video sequence regarding at least one of resolution, frame rate, and image quality. The super bitstream generating section generates a super bitstream including first to nth bitstreams generated by the video encoding section and required header information.
