Abstract
In a method for coding a moving picture image, in which the moving picture image is coded into a digital moving picture stream when the moving picture image is transmitted via a network, the moving picture image is coded in such a manner that a data unit including a synchronous signal corresponds or conforms to a data transmission unit on the network, or, the moving picture image is coded in such a manner that a synchronous signal is included in a position near a head of respective data transmission units on the network. Therefore, in the digital moving picture stream generated according to the invention, the header of the synchronous layer is included in every maximum length of the IP packet in the variable length packet switching method and in every size of the time slots in the variable bit rate TDM.
