Video distribution system, terminal device, and video data distribution device

A video data distribution device comprising a processor configured to execute instructions stored in a memory in communication with a terminal device, wherein the processor is configured to:

• acquire identification information representing first video data, which is generated from an original video, from the terminal device;
• acquire setting information including presentation-start-point information representing a presentation-start point to start presenting second video data, which is generated from the original video after the presentation-start point, from the terminal device;
• and
• output to the terminal device the second video data, which is generated from the original video captured by a plurality of cameras disposed at different positions with reference to an identification information list representing the identification information in association with the first video data, the second video data, and the original video.

An information distribution device comprising a processor configured to execute instructions stored in a memory in communication with a terminal device, wherein the processor is configured to:

• acquire video data;
• generate motion information representing a motion of a model representing a target image extracted from the video data, wherein the motion information is stored on a storage unit in association with target image information representing the target image;
• acquire terminal information of the terminal device representing a constraint regarding granularity of images displayable with the terminal device based on either performance information or communication quality information;
• adjust an information volume of the motion information to satisfy the constraint according to the terminal information so as to generate information-volume-adjusted motion information;
• and
• distribute the information-volume-adjusted motion information to the terminal device.
