AI Technical Summary

Problems solved by technology

The network environment of most users cannot meet the bandwidth requirement of 80Mbps
For the vast majority of existing terminal devices, it is impossible to decode 4320p video. Even if some devices can decode, the energy consumption is very high.

Embodiment Construction

[0025] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0026] The term "computer equipment" in this context, also referred to as "computer", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and The memory is realized by the processor...

Abstract

The invention provides a video playing method and device, and the method comprises: determining a cutting image falling in a current visible region of a user, enabling user equipment and correspondingservice equipment to appoint the number of cutting copies after a current panoramic video is unfolded, and obtaining each cutting image through cutting; requesting to obtain corresponding video datafrom the service equipment according to the cut image falling in the current visible area of the user; rendering and displaying the video data, superposing a bottom layer, and displaying low-resolution video content corresponding to the current panoramic video by the bottom layer.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a video playing technology. Background technique [0002] 360-degree video can bring an immersive viewing experience, and it is also an important way to watch movies in the future. The structural characteristics of 360-degree video make it impossible for users to see the content outside the field of vision. Therefore, the actual effective content only accounts for a very small part of the total amount of video transmission, which causes a great waste of bandwidth resources. For example, assuming that the field of view (Field Of View, FOV) is 90 degrees, and the resolution of the 360-degree video is 1080p, then the quality of the picture that the end user can see is only equivalent to that of a normal 270p video. If you want to achieve the quality of 1080p ordinary video, then the resolution of the original 360-degree video should be at least 4320p. There will be two problems ...
