Embodiment Construction

[0042] The technical solutions in the embodiments of the present application are described in more detail below.

[0043] see Figure 1A , is a schematic diagram of the architecture of a video playback system provided in an embodiment of the present application. The video playback system includes a client, a playback authentication server, a CDN scheduling device, a CDN origin server, a CDN edge node device, and a watermark server. These devices are further introduced below.

[0044] A client, or client, is a device that corresponds to a server and provides local services for clients. Various applications can be run on the client. Except for some applications running locally, the running of applications on the client generally requires the server to provide corresponding services. In the embodiment of the present application, the client may be a mobile phone, a computer, a tablet computer, a notebook computer, a wearable device, a multimedia device, and other devices capable...

Abstract

The embodiment of the invention discloses a video playing method and related equipment, which can reduce playing starting time delay of a video under the condition of playing the video with a watermark. The method comprises: after a CDN source station server receiving a first request sent by a client through CDN edge node equipment, a play starting index file being generated in real time, the playstarting index file comprising a download address corresponding to a play starting playing sequence, the play starting playing sequence being a video clip at the beginning of the video or a sequencecorresponding to the video clip after the video skips the title; and then, the CDN source station server sending the playing starting index file to the client through the CDN edge node equipment. Dueto the fact that the playing starting index file contains a small amount of data, the generation time and the transmission time are short, the client side can obtain the playing starting index file ina short time, video content is downloaded according to the downloading address corresponding to the playing starting playing sequence for playing starting, and the purpose of reducing the video playing starting time delay is achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video playing method and related equipment. Background technique [0002] In order to prevent the video from being illegally leaked, the video content provider usually adds a watermark (watermarking) to the video. The watermark added to the video is generally an implicit watermark, which is a digital signal for identification and will not affect the visual quality of watching the video. If the video is illegally leaked, the watermark information in the leaked video can be used to trace which user leaked the video, so as to protect the legitimate rights and interests of the video content provider. [0003] The method of adding watermark on the cloud side is a commonly used watermarking method at present. The principle of the method is as follows: firstly, a video is transcoded into two video media of stream A and stream B through a transcoding platform, and the vid...
