Claim Text:
1. A video presence method, comprising: receiving a three-dimensional (3D) description information sent by a remote end, wherein the 3D description information describes a 3D video capability of the remote end; performing 3D video capability adaptation based upon the 3D video capability of the remote end and a local 3D video capability to obtain a locally supported 3D description information, wherein the locally supported 3D description information includes a 3D video capturing end parameter and a 3D video displaying end parameter, wherein the 3D video displaying end parameter includes at least one of a number of 3D video displaying devices, a 3D video displaying device type, a number of viewpoints, an ideal viewing distance, and a maximum displaying parallax, and wherein the 3D video capturing end parameter includes at least one of a number of 3D video capturing devices, a 3D video capturing device type, and a 3D video capturing device spatial position relationship; receiving a multi-viewpoint 3D video signal from the remote end; identifying multiple viewpoint image streams in the multi-viewpoint 3D video signal based upon the locally supported 3D description information; and displaying alternately the multiple viewpoint image streams in sequence in a viewing area, wherein the multiple viewpoint image streams include a plurality of viewpoints, wherein a distance between each two neighboring viewpoints is equivalent to a preset pupillary distance.
