First Claim
1. A content reproduction apparatus for reproducing a multi viewpoint video content formed from a plurality of viewpoint videos imaged simultaneously by a plurality of different video cameras, comprising:
- circuitry configured toprocess one of the plurality of viewpoint videos for display to a user,receive a viewpoint change request from the user, anddetermine which subset of the plurality of viewpoint videos is required to display a viewpoint corresponding to the viewpoint change request based on a movement direction associated with the viewpoint change request and a View Relation Table (VRT) associated with the multi viewpoint video content, whereinthe VRT indicates which of the plurality of viewpoint videos is linked to the one of the plurality of viewpoint videos and a movement direction relative to the one of the plurality of viewpoint videos for each of the plurality of viewpoint videos that is linked to the one of the plurality of viewpoint videos.

1. A content reproduction apparatus for reproducing a multi viewpoint video content formed from a plurality of viewpoint videos imaged simultaneously by a plurality of different video cameras, comprising:
-
circuitry configured to process one of the plurality of viewpoint videos for display to a user, receive a viewpoint change request from the user, and determine which subset of the plurality of viewpoint videos is required to display a viewpoint corresponding to the viewpoint change request based on a movement direction associated with the viewpoint change request and a View Relation Table (VRT) associated with the multi viewpoint video content, wherein the VRT indicates which of the plurality of viewpoint videos is linked to the one of the plurality of viewpoint videos and a movement direction relative to the one of the plurality of viewpoint videos for each of the plurality of viewpoint videos that is linked to the one of the plurality of viewpoint videos. - View Dependent Claims (2, 3, 4, 5, 6)

7. A content reproduction method for reproducing a multi viewpoint video content formed from a plurality of viewpoint videos imaged simultaneously by a plurality of different video cameras, comprising:
-
processing, by circuitry of a content reproduction apparatus, one of the plurality of viewpoint videos for display to a user; receiving, by the circuitry, a viewpoint change request from the user; and determining, by the circuitry, which subset of the plurality of viewpoint videos is required to display a viewpoint corresponding to the viewpoint change request based on a movement direction associated with the viewpoint change request and a View Relation Table (VRT) associated with the multi viewpoint video content, wherein the VRT indicates which of the plurality of viewpoint videos is linked to the one of the plurality of viewpoint videos and a movement direction relative to the one of the plurality of viewpoint videos for each of the plurality of viewpoint videos that is linked to the one of the plurality of viewpoint videos. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-transitory computer-readable medium storing a program which when executed by a computer causes the computer to perform a method for reproducing a multi viewpoint video content formed from a plurality of viewpoint videos imaged simultaneously by a plurality of different video cameras, the method comprising:
-
processing one of the plurality of viewpoint videos for display to a user; receiving a viewpoint change request from the user; and determining which subset of the plurality of viewpoint videos is required to display a viewpoint corresponding to the viewpoint change request based on a movement direction associated with the viewpoint change request and a View Relation Table (VRT) associated with the multi viewpoint video content, wherein the VRT indicates which of the plurality of viewpoint videos is linked to the one of the plurality of viewpoint videos and for each of the plurality of viewpoint videos that is linked to the one of the plurality of viewpoint videos a movement direction relative to the one of the plurality of viewpoint videos.
