Abstract:
A method of coding video comprising:a video coding step for coding one or a plurality of pieces of still picture information of pro-video information in which video is digitized according to coding parameters, the pro-video information consisting of the plurality of still picture information; a processing capability decision step for deciding processing capability of coding apparatus which performs the video coding step, and outputting a decision result; and a coding parameter resolution step for 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 capability of the coding apparatus, and one or a plurality of coding parameters that affect an amount of processing of coding in the video coding step; wherein the processing capability decision step includes: a video buffering step in which a buffering processing temporarily storing the input pro-video information in a buffer of the coding apparatus is performed with a series of still picture information constituting the pro-video information sequentially being preserved while the still picture information read and coded in the coding step sequentially abandoned, and a frame rate control step in which control is executed so that the series of still picture information is preserved in the video buffering step at a prescribed frame rate decided on the basis of the given frame rate, and the decision of processing capability is performed on the basis of an amount of the pro-video information temporarily stored in the video buffering step.
