METHOD AND DEVICE FOR ACQUIRING 3D FORMAT DESCRIPTION INFORMATION

摘要

Embodiments of the present invention provide a method and device for acquiring 3D format description information. The method comprises: receiving an out-of-band message carrying 3D format description information and sent by a sender, a client receiving the out-of-band message before joining and participating in a multimedia session initiated by the sender; parsing the out-of-band message, so as to acquire the 3D format description information from the out-of-band message. In the method and device for acquiring 3D format description information provided by the embodiments of the present invention, the client can receive the 3D format description information before acquiring the video, so that the client can determine whether the client matches the format adopted by the 3D video before receiving the video, thereby improving the speed of matching determination, decreasing the overheads for receiving and processing the video, reducing the power consumption, and reducing the load on the receiving device.
