FRAME RATE CONTROL METHOD, FRAME RATE CONTROL APPARATUS, AND FRAME RATE CONTROL PROGRAM

摘要

An objective of the present invention is to alleviate instantaneous increases in encoder computation volume and information volume as a result of encoding without increased delays even when input timing of inputted video fluctuates rather than staying constant. Provided is a frame rate control method with which a frame rate of inputted video is adjusted to a frame rate at which an encoder is capable of encoding, comprising: a step of assessing whether the number of pictures inputted during a prescribed duration of time prior to the input of a picture to be assessed for dropping exceeds a prescribed threshold; and a step of discarding the picture to be assessed when the number of pictures exceeds the threshold, and treating the picture to be assessed as a subject for encoding when the number of pictures does not exceed the threshold.
