Problems solved by technology

[0003] However, for users who watch broadcast programs for a long time in the CDN system, there is no room for reasonable optimization of resources occupied by the users, because the construction cost determines the capacity limit
The video transmission of the CDN system must be restricted by the number of concurrent users of the service. When the peak usage is reached, the transmission quality cannot be guaranteed. Especially in broadcast video applications, the limitations of the CDN system will be exposed, and its cost performance is not high.

Embodiment 1

[0042] figure 1 It is a flowchart of a method for a hybrid CDN video stream distribution network provided by an embodiment of the present invention.

[0043] refer to figure 1 , the execution body is a CDN edge server, and the method includes the following steps:

[0044] Step S101, receiving play request information sent by the user terminal, where the play request information includes play content attribute information;

[0045] Step S102, allocate corresponding program content information according to the broadcast content attribute information, and send the program content information to the hybrid CDN access device through the hybrid CDN, so that the hybrid CDN access device converts the program content information into a network protocol IP data flow, and Send the IP data stream to the user terminal.

[0046] Here, the program content information includes broadcast content information and / or on-demand content information, and the hybrid CDN includes HFC network QAM mo...

Embodiment 2

[0060] image 3 It is a system schematic diagram of a hybrid CDN video stream distribution network provided by Embodiment 2 of the present invention.

[0061] refer to image 3 , the system includes: a CDN edge server 10 , a hybrid CDN access device 20 and a user terminal 30 .

[0062] The CDN edge server 10 is configured to receive the play request information including the play content attribute information sent by the user terminal 30, allocate corresponding program content information according to the play content attribute information, and send the program content information to the hybrid CDN access device 20 through the hybrid CDN ;

[0063] The hybrid CDN access device 20 is configured to convert the program content information into an IP data stream of the network protocol, and send the IP data stream to the user terminal 30 .

[0064] Further, the program content information includes broadcast content information and / or on-demand content information, and the hybri...

Embodiment 3

[0069] Figure 4 It is a schematic diagram of a system application scenario of a hybrid CDN video stream distribution network provided by Embodiment 3 of the present invention.

[0070] refer to Figure 4 , the system includes a user terminal device, a hybrid CDN access device, a hybrid CDN, a CDN edge node, and an LC (Local Cache). The LC is used for caching local programs.

[0071] Among them, user terminal equipment includes smart TV, smart phone and IP gateway; hybrid CDN includes HFC network QAM modulation channel and TCP / IP broadband access network; CDN edge node includes program stream distribution server and local traffic management server, program stream distribution server and the local traffic management server can constitute a CDN edge server, and the functions of the program stream distribution server and the local traffic management server are distribution and scheduling respectively.

[0072] The user terminal equipment is connected to the hybrid CDN access de...

Abstract

The invention provides a method and system for a hybrid-CDN (Content Delivery Network) video stream delivery network. The method comprises the steps of receiving broadcasting request information sent by a user terminal, wherein the broadcasting request information comprises broadcasting content attribute information; and allocating corresponding program content information according to the broadcasting content attribute information and sending the program content information to a hybrid-CDN access device through a hybrid-CDN, thereby enabling the hybrid-CDN access device to convert the program content information into IP data streams and send the IP data streams to the user terminal. The video broadcasting performance is integrated into a CDN system through the hybrid-CDN. The performance and capacity for a great number of users to watch real-time video streams are solved. The video service capability of a CDN edge node is improved.

Description

technical field [0001] The invention relates to the technical field of broadband communication, in particular to a method and a system for a hybrid CDN video stream distribution network. Background technique [0002] IP network-based video stream transmission technology brings new TV broadcasting and transmission methods to Internet video / TV. PCs, Pads, and smartphones can watch broadcast TV and on-demand TV through fixed or mobile broadband networks, but broadband networks are TCP / TV The IP communication network is based on the principle of best-effort transmission. For the transmission of real-time video streams, there may be congestion, delay, jitter, etc. in the network, which may cause video image freezes, frame loss, retransmissions, etc., which seriously affect viewing and playback. Avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission, make content transmission faster and more stable, and build a CDN (Content Deliver...
