Verfahren zur Video- und Audiokodierung sowie Vorrichtung zur Kodierung

摘要

A method of coding video comprises the steps of: coding one or a plurality of still picture information of pro-video information consisting of the plurality of still picture information in which video is digitized according to coding parameters; and deciding one or more coding parameters based on one or more of resolution of the pro-video information, frame rate required for reproducing coded data resulting from coding, processing performance indicating processing capability of the coding apparatus which performs the video coding step, and one or a plurality of coding parameters which affects amount of processing of coding in the video coding step. Also disclosed is a method for varying audio coding parameters, and a method for sharing CPU time to execute concurrent tasks (audio and video coding, other tasks).
