Problems solved by technology
For ultra-high-definition resources of ethnic minority culture, the advantage of the collected video is that it can better retain the details of the image, and can be partially zoomed in for image recognition and related research. However, traditional video display does not provide targeted adjustment of the image size for image details. , frame rate and resolution

Embodiment 1
[0047] Embodiment 1: An ultra-high-definition dynamic image display method based on big data distributed storage technology, general minority cultural video resources, the quality of the collected images is high-quality ultra-high-definition, using big data distributed storage and distributed computing, etc. The related technology organizes, processes, stores and distributes ultra-high-definition video resources of ethnic minorities, and realizes dynamic playback of ultra-high-definition video resources.
[0048] figure 1 Shown is the flow chart of the present invention, specifically comprises the following steps:
[0049] Step1: Dynamic image processing stage:
[0050] Step1.1: Losslessly compress the original ultra-high-definition ethnic minority cultural video resources using the H.265 standard. During this process, the ultra-high-definition video quality and clarity of the ethnic minority resources will not change, but will be reduced by nearly 90% more storage space.

The invention relates to an ultra-high-definition dynamic image display method based on big data distributed storage technology, and belongs to the technical field of multi-level transmission and playback of dynamic images. The present invention includes a dynamic image processing step and a dynamic image playing step. For ultra-high-definition video resources with little change between video frames, multi-level resolution and multi-level image frame sampling processing is performed on it in the early stage, and the image is divided into blocks The cutting process ensures the copyright security of dynamic images and improves transmission efficiency. A distributed high disaster recovery mechanism is used for storage. During playback, the image data in the server cluster is obtained according to the parameters, and the parameters can be dynamically adjusted to meet the user's playback needs. Using high-efficiency distributed computing to cut and process multi-level images, improve the efficiency of image preprocessing, and save time in the preprocessing stage.
Description
technical field [0001] The invention relates to an ultra-high-definition dynamic image display method based on big data distributed storage technology, and belongs to the technical field of multi-level transmission and playback of dynamic images. Background technique [0002] The protection and inheritance of cultural resources of ethnic minorities is a very important task for us. With the development of the Internet and the improvement of the quality of life, people have higher and higher requirements for image quality, and the playback of ultra-high-definition cultural video resources There are many problems in the display. At present, the traditional video display platform in China has not yet been able to support 4K resolution playback. For ultra-high-definition ethnic minority cultural resources, smooth and clear display is the key to inheriting ethnic minority cultural videos. It is the most basic requirement for resources, and there are also related requirements for s...
