FALLING BACK FROM THREE-DIMENSIONAL VIDEO

摘要

Disclosed are techniques for allowing a fallback from downloading and presenting a three-dimensional (3D) media content item to a 2D version of the same content item. During the download, a triggering condition is noted, such as network congestion or resource starvation on the receiving device. The receiving device requests a fallback and then begins to receive the 2D version of the media content item. (Generally, the 2D content item is downloaded beginning at a point specified by the recipient device rather than from the beginning.) The 2D version is presented to the user of the recipient device in place of the 3D version. If the triggering condition is resolved, then the download and presentation can resume in 3D, either on the request of the recipient device or by the download server noting the resolution of the triggering condition.

主权项

1. A method for a personal communications device to fall back from receiving a three-dimensional (3D) version of a media content item to a two-dimensional (2D) version of the media content item, the method comprising:
receiving, by the personal communications device from a 3D-media server, at least a portion of the 3D version of the media content item; sending, by the personal communications device to the 3D-media server, in response to a triggering condition, a fallback message requesting that at least a portion of the 2D version of the media content item be sent to the personal communications device instead of the 3D version; and receiving, by the personal communications device from a 2D-media server, at least a portion of the 2D version of the media content item.
