Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme to the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments.Based on described embodiments of the invention, ordinary skill
The every other embodiment that personnel are obtained, belongs to the scope of protection of the invention.
Fig. 1 is refer to, the embodiment of the present invention provides a kind of sending method of 3D video flowings, and the sending method includes：
Step S11：Obtain the left eye picture and right eye picture of 3D videos；
In the embodiment of the present invention, the 3D videos can be TV station 3D video frequency programs, or other need transmission
3D videos.Wherein, the every 3D display pictures in 3D videos correspond to a left eye picture and right eye picture respectively.
Step S12：Left-eye video stream is generated according to the left eye picture, right eye video is generated according to the right eye picture
Stream；
That is, left eye picture and right eye picture is individually enclosed in different video flowings.
Step S13：The left-eye video stream and right-eye video stream are sent to receiving terminal.
Left-eye video stream and right-eye video stream are the video flowings of two-way independence, are not interfere with each other.
Under normal circumstances, it is excellent in order to receiving terminal can immediately use 3D mode playbacks when 3D video flowings are received
Selection of land, while the left-eye video stream and right-eye video stream are sent into receiving terminal.
In the embodiment of the present invention, the left eye picture and right eye picture of 3D video flowings are respectively adopted the video flowing of two-way independence
Encapsulation is sent, and receiving terminal is played using 3D play mode if desired after the 3D video flowings are received, can respectively to left eye
Video flowing and right-eye video stream are decoded, and obtain left eye decoded picture and right eye decoded picture, are carried out 3D and are shown, if desired
Using 2D play mode play, can only to left-eye video stream and right eye video in video flowing all the way decode, solved
Code picture, and carry out 2D and show.
That is, using the sending method of the 3D video flowings described in the embodiment of the present invention, 2D display devices can also
3D videos normally are watched, 3D display devices can still keep 3D display effects, so as to improve Consumer's Experience.
The sending method of the embodiment of the present invention can apply to cable digital TV business, using broadcasting and TV transmission network to
Top box of digital machine in user family sends 3D video frequency programs, when the display device in user family is 3D display devices, teaching machine
