Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way intended as any limitation of the disclosure, its application or uses. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0033] The inventors have found through research that video codec standards such as H.264 have a video compression function. However, these video coding standards, as general coding methods, only perform mathematical calculations at the coding level, but do not make f...

Abstract

The invention provides a method and device for processing video data, a cloud server, an edge node, a content distribution network and a computer readable storage medium, and relates to the field of content distribution networks. The method for processing the video data comprises the following steps that: the cloud server performs down-sampling on the video data to obtain down-sampled data; the cloud server uses the down-sampled data and the video data to train a super-resolution convolutional neural network so as to allow the super-resolution convolutional neural network to be configured to process the down-sampled data to obtain the video data; and the cloud server sends the model parameters of the super-resolution convolutional neural network and the down-sampled data to an edge node to indicate the edge node to obtain the video data by using the model parameters and the down-sampled data. According to the invention, the consumption of video service on storage space and network transmission bandwidth can be reduced.

Description

technical field [0001] The present disclosure relates to the field of content distribution network, and in particular to a method and device for processing video data, a cloud server, an edge node, a content distribution network, and a computer-readable storage medium. Background technique [0002] Video business is an important business in the Internet field. With the continuous growth of film sources and users, the consumption of storage space and network transmission bandwidth is increasing, which has become an important problem faced by the industry. [0003] Taking the edge nodes in the content distribution network as an example, in terms of video content storage, edge nodes usually need to cache multiple video versions with different resolutions in order to meet the resolution requirements of different terminal devices and save transcoding time, thus exacerbating the Storage pressure on edge nodes. It can be seen that how to compress video data to reduce storage spac...
