Abstract
[TASK] To provide a recommended viewpoint to a user who is not familiar with a switching operation for switching a viewpoint of a free viewpoint motion image.[SOLUTION TO PROBLEMS]When a user gives a switching instruction for switching a viewpoint and a viewpoint direction by user terminals 3a to 3n−1, the switching instruction is sent to a distribution computer 2. The distribution computer 2 stores the switching instruction for each user ID and for each content ID. The distribution computer 2 generates recommended projection characteristic data on the basis of a plurality of switching instructions for free viewpoint motion image data corresponding to its content ID. When a new distribution request for data corresponding to the content ID is received from the user terminal 3n, the distribution computer 2 distributes recommended projection characteristic data together with free viewpoint motion image data.
