Problems solved by technology
[0005] Embodiments of the present invention provide a live video transmission method, device, and system, which are used to solve the problem that the above-mentioned M2U device needs to rely on the ability of the CPU to convert video data into HTTP messages. However, the ability of the CPU to process HTTP traffic is limited. , when there are many users, the live video service cannot be realized

Embodiment Construction
[0142] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings in the embodiments of the present invention.
[0143] figure 1 It is a structural diagram of the transmission system of the live video of the present invention, such as figure 1 As shown, the live video system mainly includes the client on the user side, for example: a live application (English: application, APP for short), M2U equipment, and U2M equipment. In this system architecture, the U2M equipment transmits OTT The server obtains the video data, and then distributes the video data to different M2U devices through multicast (each U2M device is connected to multiple M2U devices), and the M2U device sends the video data to the client to play to the user according to the request of the client. In this process, the phy...

The present invention provides a live video transmission method, device and system, comprising: an M2U device receives a UDP request sent by a client, including a live channel identifier, for requesting video data of a live channel corresponding to the live channel identifier, including a multicast address or URL, and obtain the video data corresponding to the live channel identifier, the M2U device obtains the source IP address and source port of the UDP request as the destination IP address and destination port for subsequent UDP unicast messages sent to the client. After M2U receives the multicast video data corresponding to the UDP request, it modifies the multicast destination IP address and destination port to the unicast destination IP address and destination port of the client obtained above, and sends the video data to the client in UDP unicast mode . It does not require the CPU to perform protocol conversion on video data, and directly transmits video data in UDP unicast mode through hardware forwarding, which can effectively improve the throughput of M2U devices.
Description
technical field [0001] Embodiments of the present invention relate to Internet technologies, and in particular to a live video transmission method, device and system. Background technique [0002] As live video is increasingly popular with users, many over-the-top (English: over-the-top, OTT for short) video websites provide live video services. However, the feature of live video is that users watching the same channel see all Duplicate content, that is, for users watching live channels, a large number of repeated data packets are transmitted in the network, occupying a large amount of network bandwidth and bringing a large amount of network settlement fees to operators. [0003] In order to overcome the above problems, a multicast OTT technology is proposed, which reduces network traffic and reduces the load of the video source server through the multicast bearer network. Unicast to multicast (English: unicast to multicast, referred to as: U2M) equipment obtains video data...
