Embodiment 1

[0038] figure 1 It is a flowchart of a panoramic video distribution method based on user characteristics in a preferred embodiment of the present invention; the method includes the following steps:

[0039] Step0: Arrange the multi-channel spliced ​​code streams of the panoramic video according to the order of camera acquisition angles of view, and then record the sequence of the multi-channel spliced ​​code streams of the panoramic video after sorting as

[0040] {stream 1 ,stream 2 ,...,stream N-1 ,stream N}, and the corresponding camera acquisition view sequence is denoted as {θ 1 ,θ 2 ,...,θ N-1 ,θ N}.

[0041] Among them, stream n Indicates the nth spliced ​​code stream arranged according to the sequence of camera acquisition angles of view, N represents the number of spliced ​​code streams, n=1,2,...,N; θ n Indicates stream n The corresponding camera acquisition angle of view; "Arranged in the order of camera acquisition angle of view" can be arranged in asce...

Embodiment 2

[0073] image 3 It is a structural diagram of a panoramic video distribution system based on user characteristics in a preferred embodiment of the present invention; the system includes:

[0074] The mosaic code stream arrangement module is used to arrange the multi-channel spliced ​​code streams of the panoramic video according to the order of the camera acquisition angle of view, and then record the sequence of the multi-channel spliced ​​code streams of the panoramic video after sorting as

[0075] {stream 1 ,stream 2 ,...,stream N-1 ,stream N}, and the corresponding camera acquisition view sequence is denoted as {θ 1 ,θ 2 ,...,θ N-1 ,θ N}.

[0076] Among them, stream n Indicates the nth spliced ​​code stream arranged according to the sequence of camera acquisition angles of view, N represents the number of spliced ​​code streams, n=1,2,...,N; θ n Indicates stream n The corresponding camera acquisition angle of view; "Arranged in the order of camera acquisition a...

Abstract

The invention discloses a panoramic video distribution method and system based on user characteristics, and belongs to the technical field of panoramic video distribution. The method comprises the following steps: self-adaptively distributing multichannel code streams for panoramic video mosaicing by use of the continuity of user watching characteristics, thereby enabling the panoramic video to distribute the code streams as required when the network is in congestion. The fluency of the panoramic video playing is improved while not influencing the watching effect of audience.

Description

technical field [0001] The present invention relates to the technical field of panoramic video distribution, in particular to a method and system for panoramic video distribution based on user 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. 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 ...
