TRANSMISSION METHOD, RECEPTION METHOD, TRANSMISSION DEVICE AND RECEPTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transmission method, a reception method, a transmission device and a reception device that can simplify the construction of the devices and reduce the processing amounts of the devices when data are transmitted by using a method such as MMT (MPEG Media Transport).SOLUTION: A transmission method provides sample data with header information containing MP4 construction information whose content varies according to whether a sample data present time is settled or not. When meta data corresponding to sample data are not transmitted, S1002; No, and according to whether the present time of the sample data is settled or not, header information which does not contain any MP4 construction information is provided to the sample data (S1004), and transmitted.SELECTED DRAWING: Figure 49
