Abstract:
1. A moving image data distribution system for distributing reproduction content data that is hierarchically structured so that lower layer data is synthesized with upper layer data to form high quality data, wherein the moving image data distribution system comprising a transmitting apparatus and a receiving apparatus, the transmitting apparatus including: first hardware including a processor; a transmission data storing unit that stores the reproduction content data; an upper layer first data length determining unit implemented at least by the first hardware to determine a data length of the upper layer first data based on a reproduction delay time from when the receiving apparatus receives only the upper layer data to when the receiving apparatus reproduces the reproduction contents; an upper layer first data transmitting unit implemented at least by the first hardware to read upper layer first data determined based on the upper layer first data length from the storing unit, and transmitting the upper layer first data to the receiving apparatus; and an upper layer subsequent data transmitting unit implemented at least by the first hardware to read upper layer subsequent data subsequent to the upper layer first data from the storing unit, and transmitting the upper layer subsequent data to the receiving apparatus, the receiving apparatus including: second hardware including a processor; a lower layer data storing unit that stores the lower layer data; a hierarchical data synthesizing unit implemented at least by the second hardware to synthesize the lower layer data with the upper layer first data or the upper layer subsequent data; and a reproducing unit implemented at least by the second hardware to reproduce high quality data synthesized by the hierarchical data synthesizing unit, wherein said upper layer first data and said upper layer subsequent data are included in the same upper layer and are in anteroposterior relationship along the playing time axis of said reproduction contents.
