Abstract: Disclosed are a method and a device for processing live video. The method for processing live video includes: receiving, by a CDN server, a request for playing video sent from a player, wherein a video format supported by the player and identification information of the requested video are carried in the request; obtaining an access path of the requested video according to the identification information of the requested video; obtaining the requested video from a resource server corresponding to the access path; converting a format of the requested video to the video format supported by the player; and sending the player the requested video which can be played on the player.

Abstract: Disclosed are a method, an electronic device and a system for controlling a pull stream. The method includes: receiving a user request forwarded by a content delivery network (CDN) server, wherein the user request is used for requesting to watch a live video; detecting whether a stream state of the live video at a source server is on live, wherein the stream state is a stream state of a live video of the user request; instructing the source server to pull a video stream of the live video to a third-party server if the stream state at the source server is not on live; receiving a stream state returned by the source server, wherein the stream state returned by the source server is on live; and sending a back-to-source path of the video stream to the CDN server so that the CDN server sends the back-to-source path to a client.

Abstract: Disclosed are a method, a device and a system for playing live video. The method includes: sending, by a client, a play request for playing live video to a control center to enable the control center to count the number of clients viewing the live video and to return a content sharing client list to the client according to a preset policy; according to the content sharing client list returned by the control center, establishing data communication links with the clients in the list; sending subscription requests for the live video via the data communication links; receiving the packet data information sent from the clients according to the subscription requests; and combining the packet data information sent from the clients to obtain continuous live video for playing.

Abstract: Disclosed are a method, a device and a system for uploading live video. The method includes: receiving, by an edge server, a live video uploading request from a client, wherein the edge server is a node server in a CND system which provides data transmission service to the client; sending the uploading request to a control center, so that the control center configures uploading path information according to the uploading request; receiving, from the control center, the uploading path information, indicating a data transmission path and calculated in real time by the control center according to a preset uploading path configuration policy; and uploading live video data of the client to a live broadcasting platform according to the uploading path information.

Abstract: The present disclosure provides a method, a device and a system for playing live video. The technical solutions employed by embodiments of the present disclosure include: receiving, by an edge server, a play request from a client requesting to view live video, wherein the edge server is a node server in a content delivery network system which provides data transmission service to the client; sending the play request to a control center, so that the control center configures data download path information according to the play request; receiving, from the control center, the data download path information; obtaining live video data corresponding to the play request from a live broadcasting platform according to the data download path information; and sending the live video data to the client so that the client can play the live video.

Abstract: Disclosed are a data processing method and apparatus in a content delivery network. The method comprises: sending a data request packet for multimedia content; receiving IP addresses of a plurality of remote devices, the IP addresses of the plurality of remote devices being assigned by a scheduling server in response to the data request packet for multimedia content; accessing the plurality of remote devices according to the received IP addresses of the plurality of remote devices; and downloading multimedia file content corresponding to the data request packet from one or more of the plurality of remote devices according to the data request packet. As disclosed a scheduling server can schedule, according to a data request packet for multimedia content, a terminal device of a user to access a remote device for a particular purpose, which improves access efficiency, and makes data sharing between terminal devices more efficient, improving user experience.
