Abstract:
1. A method used by a media source to deliver at least portions of media content to a first viewer system and a second viewer system, the media content being three-dimensional content representing a first visual perspective, a second visual perspective, a third visual perspective and a fourth visual perspective, the method comprising: receiving a first request from the first viewer system for a primary media stream; constructing the primary media stream from a first portion of the media content, the first portion containing representations of at least one but not all of the first visual perspective, the second visual perspective, the third visual perspective and the fourth visual perspective; delivering the primary media stream to the first viewer system; receiving a second request from the second viewer system for a second media stream, the second request being received after having delivered a first portion of the primary media stream to the first viewer system; constructing a secondary media stream from a second portion of the media content, the second portion containing representations of at least one but not all of the first visual perspective, the second visual perspective, the third visual perspective and the fourth visual perspective, the second portion containing a representation of at least one visual perspective not included in the first portion of the media content; constructing a tertiary media stream based on the first part of the primary media stream; and delivering the tertiary media stream to the second viewer system; and delivering both the primary media stream and the secondary media stream to the second viewer system to enable the primary and secondary media streams to be combined to generate a stereoscopic three-dimensional view for display by a display screen of the second viewer system.
