Embodiment 1

[0028] figure 1 It is a flow chart of a panoramic video distribution method based on visual characteristics in a preferred embodiment of the present invention, and the method includes:

[0029] Step1: Send a const second panoramic video multi-channel stream stream n , n=1,2,...,N.

[0030] in, const represents the time window duration parameter; t 0 Indicates the initial buffering time of the sent code stream, generally 3-6 seconds; t c Indicates the buffering duration of the sending code stream; nt indicates the time window label, the initial value is 1; stream n Indicates the nth spliced ​​code stream of the panoramic video, and N represents the number of spliced ​​code streams.

[0031] Step2: In the const second time window, send the bandwidth parameters and visual angle information in the time window.

[0032] in, wbit nt Indicates the bandwidth parameter of the ntth time window; mean (variable | condition) indicates the mean value of the variables satisfying t...

Embodiment 2

[0050] figure 2 It is a structural diagram of a panoramic video distribution system based on visual characteristics in a preferred embodiment of the present invention, and the system includes:

[0051] Multi-channel stream sending module, used to send const second panoramic video multiple stream stream n , n=1,2,...,N.

[0052] in, const represents the time window duration parameter; t 0 Indicates the initial buffering time of the sent code stream, generally 3-6 seconds; t c Indicates the buffering duration of the sending code stream; nt indicates the time window label, the initial value is 1; stream n Indicates the nth spliced ​​code stream of the panoramic video, and N represents the number of spliced ​​code streams.

[0053] The bandwidth parameter and visual angle information sending module is used to send the bandwidth parameter and visual angle information in the const second time window within the time window.

[0054] in, wbit nt Indicates the bandwidth para...

Abstract

The invention discloses a panoramic video distributing method and system based on visual characteristics. According to the method, visual characteristics of human eyes and network congestion conditions are used, and multi-path code streams formed by splicing panoramic videos are distributed adaptively. Thus, the watching effect of audiences is not influenced, and the playing smoothness of panoramic videos is improved.

Description

technical field [0001] The present invention relates to the technical field of video distribution, in particular to a panoramic video distribution method and system based on visual characteristics. Background technique [0002] Panoramic video can provide dynamic real-time video information while providing all-round visual information, so that people can see the entire dynamic scene around the camera. panoramic Figure 1 These images are generally large-resolution images, and their generation requires a lot of computational work. Compared with panoramas, panoramic videos add a new time dimension to panoramas. Therefore, the amount of calculation and data will be tens of times that of the panorama, which is a great challenge to the processing power of the hardware system and the work efficiency of the software system. When the code stream of the panoramic video is distributed and transmitted, it will put great pressure on the bandwidth of the network, and it will be a great...
