Technical Field

The present application relates to the field of data processing technology, and in particular to a data processing method, device, electronic device and storage medium.

Background Art

With the vigorous development of various technologies, users' requirements for the clarity and fluency of video services are constantly increasing. At present, high-definition video has become the mainstream, and major sports events and operators have also launched 4K and 8K live broadcast channels. With the improvement of resolution and clarity, the user's viewing experience is improved, and at the same time, the bandwidth usage for transmitting video content has also increased dramatically. In order for users to watch videos quickly and smoothly, various content operators have adopted content delivery network (CDN) technology to quickly distribute video content. Most of the time, CDN can provide users with sufficient download speed to support playback, but during network peak hours or some occasional periods, some CDN servers are overloaded, or the network equipment on the link is overloaded. At this time, the download speed from these CDN servers is not ideal, and sometimes it cannot meet the normal video playback requirements. When there is no new video content to play, it will cause jamming.

Currently, set-top boxes generally use the native player built into the Android system for playback. The client passes the playback address to the native player for downloading and playback. The native player only downloads and plays from the specified playback address. Some downloaded data is irrelevant to the business, so when downloading files, the CDN server dispatched to the server is prone to slow download speeds due to overload, congestion or other reasons.

From the above, it can be seen that the downloading efficiency of playback data in the existing technical solution is low.

DETAILED DESCRIPTION

In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

FIG1 is a flow chart of a data processing method provided in an embodiment of the present application. Referring to FIG1 , an embodiment of the present application provides a data processing method, which is applied to a download agent, and includes:

S100, sending a set-top box ID to a content delivery network CDN scheduling center; wherein the CDN scheduling center determines a target CDN server based on a play request sent by a player, and sends the play request and identification information of the target CDN server to a download agent based on the set-top box ID;

The executor of the embodiment of the present application is a download agent (AGENT), which is an independent service software running on a set-top box. It is deployed and distributed by the set-top box operator and acts as an HTTP download agent to accept playback requests from the player, download network files from the CDN server and push them to the player.

The CDN dispatch center is a centralized control system for managing and dispatching CDN nodes. The main function of the CDN dispatch center is to decide which CDN node to download the playback data from based on various factors, such as user geographic location, network topology, server load, etc., and to monitor and optimize network performance in real time.

Set-top box identification (ID) refers to an identifier used to uniquely identify a set-top box device. Each set-top box is given a unique ID during the production process to distinguish different devices. The set-top box ID is usually a number or a string.

A player is a device or software used to play multimedia content. It can read and decode files in various formats such as audio, video, and images, and convert them into a form that people can watch, listen to, or browse.

CDN servers are servers used to provide efficient content transmission and distribution. CDN servers accelerate content transmission and access by caching content on edge nodes closer to users. The target CDN server is the CDN server that is determined to download and play data.

A playback request is a request instruction from a player to a CDN dispatch center to download playback data.

An agent is installed in the set-top box. When the agent is turned on, it monitors the local set-top box ID and reports the set-top box ID to the CDN dispatch center. After receiving the set-top box ID, the CDN dispatch center checks whether the agent corresponding to the set-top box ID is online.

The player generates a play request based on the play address (or program address) selected by the user, and sends the play request to the CDN dispatch center, requesting to download the corresponding play data. The play request also carries the player ID. After receiving the play request, the CDN dispatch center obtains the player ID and then obtains the network location of the downloading user. Based on the network location of the downloading user, the CDN server adjacent to the network location of the downloading user is determined as the target CDN server to download the play data.

After the CDN dispatch center determines that the AGENT corresponding to the set-top box is online, it sends the identification information of the target CDN server to the AGENT, and dispatches the play request to the AGENT on the set-top box through the HTTP protocol 302 instruction.

S200, responding to the play request sent by the CDN scheduling center, downloading the play data from the target CDN server based on the identification information, and sending the play data to the player.

After receiving the playback request and the identification information of the target CDN server, the AGENT determines the target CDN server according to the identification information; according to the playback address in the playback request, the AGENT downloads the playback data from the target CDN server, where the playback data includes audio, video and other data. The AGENT sends the downloaded playback data to the player, and the player plays smoothly based on the playback data.

The data processing method provided in the embodiment of the present application sends a set-top box ID to a CDN dispatch center; wherein the CDN dispatch center determines a target CDN server based on a playback request sent by a player, and sends the playback request and identification information of the target CDN server to a download agent based on the set-top box ID; in response to the playback request sent by the CDN dispatch center, the playback data is downloaded from the target CDN server based on the identification information, and the playback data is sent to the player. The embodiment of the present application improves the download efficiency of playback data by determining a target CDN server and downloading playback data from the target CDN server through a download agent.

Based on the above embodiment, after downloading the playback data from the target CDN server based on the identification information, the method further includes:

S210, determining a video bit rate of the playback data based on the playback duration of the playback data and the transport stream file size;

S220, determining an average download speed of the playback data based on the download data volume and download time of the playback data;

S230: When the average download speed is lower than the video bit rate, it is determined that the download of the playback data is stalled.

The playback data in the embodiment of the present application is video, including live video, recorded video, etc.

The download agent obtains the video playback time and the size of the transport stream (TS) file recorded in the live broadcast index file (M3U8 file) according to the downloaded live broadcast index file, and calculates the video bit rate of the video according to the playback time and the transport stream file size.

The download agent calculates the average download speed of the video based on the download data volume and download time after the video has been downloaded for a period of time.

The download agent compares the average download speed with the video bit rate. When the average download speed is greater than or equal to the video bit rate, it is considered that the current video download is normal and can meet the demand. When the average download speed is less than the video bit rate, it is determined that the video download is stuck.

The embodiment of the present application improves the accuracy of determining the download status of the playback data by determining the average download speed and video bit rate of the playback data, and then determining whether the download of the playback data is stalled by comparing the average download speed and the video bit rate.

Based on the above embodiment, after determining that the download of the playback data is stuck, the method further includes:

S231, stop downloading playback data from the target CDN server, and send a change request to the CDN scheduling center; wherein the CDN scheduling center determines a backup CDN server based on the change request, and sends identification information of the backup CDN server to the download agent;

S232: based on the identification information of the standby CDN server sent by the CDN scheduling center, download the remaining playback data from the standby CDN server, and send the remaining playback data to the player.

The remaining playback data is the playback data that has not been downloaded. When the download agent determines that the download of the playback data is stuck, it considers that the quality of the current target CDN server is not good. The download agent disconnects the download connection with the target CDN server and sends a change request to the CDN scheduling center, requesting to download the remaining playback data from other CDN servers.

After receiving the change request sent by the download agent, the CDN dispatch center determines a backup CDN server close to the network location of the download user based on the network location of the download user in the playback request, and sends the identification information of the backup CDN server to the download agent.

As shown in Figure 2, the download agent receives the identification information of the backup CDN server sent by the CDN scheduling center, and determines the backup CDN server based on the identification information. The download agent downloads the remaining playback data from the backup CDN server according to the playback address in the playback request, and sends the remaining playback data to the player. The player plays smoothly based on the remaining playback data.

In the embodiment of the present application, when the download of playback data is stuck, the remaining playback data is downloaded to the backup CDN server, thereby increasing the download rate of the playback data. Stuttering and jumping of video content will reduce the user's viewing experience, and jumping playback will cause users to be unable to watch some video content, reducing the user's viewing experience. The implementation of the present application senses the download quality of the target CDN server by adding a proxy download service. When it is found that the quality of the target CDN server is poor in the current network environment, the backup CDN server is re-requested to ensure that the overall download speed meets the playback requirements and avoids stuttering and video jumping.

The embodiment of the present application deploys a download agent on the set-top box to detect in real time the download speed of the download agent downloading playback data from the target CDN server under the current network environment. The download agent registers with the CDN scheduling center when it goes online. After that, when the player of the set-top box sends a playback request to the CDN scheduling center, the playback request will be dispatched to the download agent, and the download agent will subsequently replace the download of the player on the set-top box. The download agent continuously detects the download quality of the playback data of the target CDN server during the download process. When the download quality of the playback data of the target CDN server is not good, the download agent will obtain a backup CDN server from the CDN scheduling center, and download data from the backup CDN server and push it to the player within a period of time, so as to avoid playback jams caused by poor download quality of playback data from a single CDN server due to network problems. The biggest advantage of the embodiment of the present application is that the quality perception and switching download of the CDN server can be achieved without changing the player of the set-top box.

When the CDN dispatch center determines through the set-top box ID that the download agent corresponding to the set-top box ID is in an offline state.

The CDN dispatch center determines the network location of the downloading user based on the playback request, and uses the CDN server adjacent to the downloading user's network location as the target CDN server based on the downloading user's network location, and sends the identification information of the target CDN server to the player. The player determines the target CDN server based on the identification information, downloads the playback data from the target CDN server based on the playback address selected by the user, and plays the downloaded playback data.

In the embodiment of the present application, when the download agent corresponding to the set-top box ID is in an offline state, the playback data is directly downloaded to the target CDN server through the player, which is conducive to ensuring that the playback data is downloaded in a timely manner and improving the download efficiency of the playback data.

Based on the above embodiment, determining a target CDN server based on a playback request sent by a player includes:

S410, determining a player ID based on the play request;

S420, determining the distance between the player and each CDN server based on the player ID;

S430: Use a CDN server whose distance is less than a set value as a target CDN server.

The player ID is identification information used to indicate the player location, and the player location further represents the network location of the downloading user.

When the player sends a play request, it records the player ID in the play request. The CDN dispatch center obtains the player ID based on the play request.

The CDN dispatch center determines the location of the player based on the player ID, and then determines the distance between the player and each CDN server. To select a CDN server close to the player, a set value is determined based on the download demand. When the distance between the player and the CDN server is less than the set value, the CDN server corresponding to the shortest distance is selected as the target CDN server.

The embodiment of the present application improves the efficiency of downloading playback data by selecting a CDN server adjacent to the player as the target CDN server.

Based on the above embodiment, based on the set-top box ID, determining that the download agent corresponding to the set-top box ID is in an offline state includes:
