Adaptable media stream servicing two and three dimensional content

摘要

Media sources that deliver at least portions of media content to viewer systems are described. The media content represents a plurality of camera perspectives of a single media product. A first request and a second request are both received. The first request is from a first viewer system and the second request is from a second viewer system. The first request is responded to by delivering a primary media stream to the first viewer system. The primary media stream contains a representation of at least a first of the plurality of camera perspectives. The second request is responded to by delivering both the primary media stream and a secondary media stream to the second viewer system. The secondary media stream contains a representation of at least a second of the plurality of camera perspectives. The second viewer system combines the primary and secondary media streams to display a three-dimensional view.

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.
