Regenerative manner of compressed manner and output manner and dynamic picture image data of dynamic picture image data and compressed device and output device and reproducing arrangement null of dynamic picture image

摘要

A method, apparatus and computer program for recording and reproducing moving image data at any one of a plurality of different resolution levels or a lowest resolution level to reduce reproduction time. In the invention when recording, moving image data is coded in accordance with each of the resolution levels, and a result of the coding is output to a desired media in time series. The result includes coded data corresponding to each of the resolution levels. In the invention when reproducing, one of the resolution levels at which moving image data is to be reproduced is selected, coded data corresponding to the selected resolution level is input, and the coded data corresponding to the selected resolution level is decoded to reproduce the moving image data.
