Problems solved by technology

[0004] The defect of the above-mentioned live broadcast system is that when the slice server fails, the next live stream slice with the serial number incremented corresponding to the live stream slice currently played by the player cannot be distributed to the CDN node, so that the player cannot obtain it from the CDN node. Go to the next live stream slice, so that there will be a freeze when playing

Embodiment 1

[0048] see figure 1 , is a flow chart of a live broadcast method provided in Embodiment 1 of the present invention. The method in the embodiment of the present invention may be executed by a live broadcast system implemented by hardware and / or software. The system includes: a content distribution network (CDN) node, and a primary slice server and a backup slice server deployed on the CDN node.

[0049] The method includes:

[0050] 110. When obtaining the live broadcast request transmitted by the CDN node, the main slicing server slices the live stream to obtain the live stream slice, and distributes the live stream slice to the CDN node.

[0051] 120. The primary slicing server generates the serial number of the live stream slice, and synchronizes the serial number of the live stream slice to the serial number storage library in the standby slicing server.

[0052] In operation 110, the CDN node specifically transmits the live broadcast request of the player on the user si...

Embodiment 2

[0070] see figure 2 , is a flow chart of a live broadcast method provided in Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment provides that the serial number of a new live stream slice is generated on the backup slice server, and the serial number of the new live stream slice is synchronized to the serial number storage library in the main slice server The next preferred option.

[0071] This preferred method includes:

[0072] 210. After the failure of the primary slice server is repaired, the primary slice server monitors the operation status of the standby slice server.

[0073] 220. When the primary slicing service monitors that the standby slicing server is faulty, obtain the serial number of the new live stream slice in the serial number storage library of the primary slicing server, and obtain the serial number of the new live stream slice according to the new live stream The serial number of the stream slice, s...

Embodiment 3

[0081] see image 3 , is a schematic structural diagram of a live broadcast system provided by Embodiment 3 of the present invention. The system includes: a CDN node (not shown), and a primary slice server and a standby slice server deployed on the CDN node.

[0082] The main slice server includes: a slice module (not shown) and a serial number processing module.

[0083] Wherein, the slicing module is used to slice the live stream to obtain slices of the live stream when the live request transmitted by the CDN node is obtained; the slice of the live stream is distributed to the CDN node; the serial number processing module is used to generate The serial number of the live stream slice; and synchronizing the serial number of the live stream slice to the serial number storage library in the slice server;

[0084] The standby slice server includes: an active-standby monitoring switch, a slice module (not shown) and a serial number processing module.

[0085] Wherein, the acti...

Abstract

The invention provides a webcasting method and a system. According to the invention, the method is performed in this way. Through a main segmenting server deployed at a CDN node and upon obtaining the webcasting requirement transmitted from the CDN node, the method executes the segmentation and distribution of live streaming and at the same time, synchronizes and deploys the sequence numbers of the segmentations into the sequence number storage base in the backup segmenting server deployed at the CDN node. When the backup segmenting server monitors an outage in the main segmenting server, the backup segmenting server executes the segmentation and distribution of live streaming based on the latest sequence numbers contained in its sequence number storage base. This function realizes the smooth switch between the main segmenting server and the backup segmenting server deployed at the same CDN node as well as the synchronization of sequence numbers between the two. As a result, a player is capable of obtaining segmentation of live streaming next after the current segmentation, therefore ensuring a smooth playing process.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to a live broadcast method and system. Background technique [0002] With the development of Internet technology, more and more people pay attention to webcast, especially web multimedia streaming. Through network signals, users can watch football games, sports events, major events and news online, giving users a wide and free choice. [0003] The existing live broadcast system generally slices the live stream through the slicing server, and uses CDN (Content Delivery Network, content distribution network) technology to distribute the slices of the live stream to the CDN nodes, and the CDN nodes provide the user-side players with Live service. Since there is no connection between the player and the slice server, a serial number is required to mark the live stream slice. The serial number is incrementally updated to facilitate the player to acqui...
