Transmitting and recording method, reproducing method, and reproducing apparatus of information and its recording medium

Abstract

A method of reproducing data from a recording medium, each of the data including reference time information indicating a reference time and including packet data, the method including: reproducing the data from the recording medium; obtaining a difference between respective reference times indicated by the reference time information of the reproduced adjacent data; rearranging the data on a time axis such that a time interval between adjacent data is equal to the obtained reference time difference; and outputting the rearranged data.

Benefits of technology

[0008]In the case of performing a retrieval, an editing operation, or the like on a picture or a picture group unit basis, by reading the information which was reproduced from the medium and was written in the sub information portion in the frame signal peculiar to the medium and indicates whether or not the picture or the boundary of the picture group exists in the minimum unit of the data structure peculiar to the medium and by judging the information, a reproducing position on the medium at which to reproduce the picture or the boundary of the picture group can be accurately and easily detected. Thus, a complicated control to find the position of the picture or the boundary of the picture group is unnecessary, so that the picture or the boundary of the picture group can be retrieved at a high speed.

Problems solved by technology

Therefore, in the case of performing a retrieval, an editing operation, and the like on a picture or picture group unit basis, a complicated control is needed to find a position of the picture or boundary of the picture group on the medium, so that there is a problem such that it takes a long time to find the position.
