Motion image distribution system, motion image distribution method, server for motion image distribution system, and user terminal for motion image distribution system
A motion image distribution system includes a server and a use terminal. The server generates a feature quantity table CHT1 representing a data structure of motion image encoded data VDE, and authenticates the motion image encoded data VDE by using the generated feature quantity table CHT1. Then, the server transmits the motion image encoded data VDE and the feature quantity table CHT1 to the user terminal. The user terminal generates a feature quantity table CHT2 representing a data structure of the received motion image encoded data VDE, and authenticates received motion image encoded data VDE by using the generated feature quantity table CHT2. Then, the user terminal plays back the motion image encoded data VDE and outputs motion image playback information.
