METHODS AND APPARATUS FOR CAPTURING, STREAMING AND/OR PLAYING BACK CONTENT
First Claim
1. A method of providing stereoscopic content, the method comprising:
- storing first correction information for a first camera of a first stereoscopic camera pair;
storing second correction information for a second camera of the first stereoscopic camera pair; and
operating a server to provide said first correction information and said second correction information to a playback device, said first correction information being for use in rendering image content captured by said first camera, said second correction information being for use in rendering image content captured by said second camera.

Abstract
Methods and apparatus for streaming or playing back stereoscopic content are described. Camera dependent correction information is communicated to a playback device and applied in the playback device to compensate for distortions introduced by the lenses of individual cameras. By performing lens dependent distortion compensation in the playback device edges which might be lost if correction were performed prior to encoding are preserved. Distortion correction information maybe in the form of UV map correction information. The correction information may indicate changes to be made to information in a UV map, e.g., at rendering time, to compensate for distortions specific to an individual camera. Different sets of correction information maybe communicated and used for different cameras of a stereoscopic pair which provide images that are rendered using the same UV map. The communicated correction information is sometimes called a correction mesh since it is used to correct mesh related information.
