Embodiment approach

[0129] Different types of boxes carry 3D format identification information and 3D video processing parameter information corresponding to different 3D format types. The 3D format type is indicated by the type of Box. The box whose type is fpdt is used to carry the 3D component type identification and 3D video processing parameter information corresponding to the frame packing format type. The box whose type is spif is used to carry the 3D component type identification and 3D video processing parameter information corresponding to the 2D plus auxiliary video format type. The box whose type is stif is used to carry the 3D component type identification and 3D video processing parameter information corresponding to the simulcast format type.

[0130] The definition of box is as follows.

[0131]

Abstract

The invention provides a media forwarding method, a media receiving method, a client, and a system. The media receiving method comprises: receiving a media displaying description, wherein the description includes 3-dimensional description information of a video; choosing to display according to the 3-dimensionaldescription information; sending fragment obtaining request to a server corresponding to the chosen display according to the sectioning information in the media displaying description, wherein the fragment obtaining request is used for obtaining the fragments chosen to display; and receiving the fragments required by the fragment obtaining request. The invention conquers the defect of the prior art, by which the 3-dimensional description information is received after a relatively long while when the receiver starts media receiving.

Description

technical field [0001] The embodiments of the present invention relate to media technologies, and in particular, to a media sending method, a media receiving method, a client and a system. Background technique [0002] 3D (Three Dimensional) video can adopt different formats when transmitting or storing. Common 3D format types such as: frame packing (frame packing), 2D (Two Dimensional) plus auxiliary video (2d plus auxiliary video), simulcast (Simulcast). In order to correctly process the 3D video, the server needs to provide some information to the client, which is collectively referred to as 3D format description information. The 3D format description information can enable the client to determine the 3D format adopted by the video, so that the client can process the 3D video sent by the server. For example, a 3D video is processed to obtain a left view for projection to a person's left eye and a right view for projection to a person's right eye. [0003] In the existi...
