Embodiment 1

[0030] Embodiments of the present invention will be described from the perspective of a device for detecting slow users in live network video, and the device for detecting slow users in live network video may be integrated into network devices such as servers.

[0031] A method for detecting slow users in a live network video broadcast, comprising: obtaining data fragments carrying a fragment number, the data fragments are obtained by time slicing the video data stream of the network video live broadcast, and sending the data fragments to The client side obtains the synchronization information between the data fragment number in the server and the data fragment number in the client, and detects slow users in the network video live broadcast according to the synchronization information.

[0032] Such as Figure 1a As shown, the specific process can be as follows:

[0033] 101. Obtain data fragmentation;

[0034] Wherein, the data segment is obtained by time slicing the video d...

Embodiment 2

[0073] In this embodiment, it will be described by taking the device for detecting slow users in the live broadcast of network video as an example that is specifically integrated in a server, such as a live broadcast server.

[0074] Such as Figure 2a As shown, the video live broadcast system may include a signal source, an encoder and a live broadcast server. In addition, the video live broadcast system may also include a client, wherein the encoder may be an entity independent of the live broadcast server, or may be integrated in the live broadcast server or Integrated in other network devices independent of the live server. The functions of each part of the live video system can be as follows:

[0075] (1) Signal source;

[0076] The signal source is used to send the original video data stream, and the signal source can be a satellite signal or a camera, etc.

[0077] (2) Encoder;

[0078] The encoder is used to capture the original video data stream sent by the signal...

Embodiment 3

[0101] The same as the second embodiment, this embodiment also takes the device for detecting slow users in the live broadcast of network video to be specifically integrated in a server, such as a live server, as an example for illustration. The difference from the second embodiment is that in this embodiment In , another method will be used to detect slow users in the network video live broadcast according to the synchronization information, which will be described in detail below.

[0102] In this embodiment, also with Figure 2a The illustrated video live broadcast system is used as a basis for description, see Embodiment 2 for details, and will not be repeated here.

[0103] Such as image 3 As shown, a method for detecting slow users in network video live broadcast, the specific process can be as follows:

[0104] 301. The signal source sends an original video data stream.

[0105] 302. The encoder captures the original video data stream sent by the signal source, enco...

Abstract

The embodiment of the invention discloses a method and a device for detecting low-speed users in network video live broadcast and a system. According to the embodiment of the invention, a data fragment carrying a fragment number can be acquired, wherein the data fragment is acquired by carrying out time slicing on video data streams in network video live broadcast, the data fragment is sent to a client, synchronization information between a fragment number of a data fragment in a server and the fragment number of the data fragment in the client is acquired, and then detection for the low-speed users in network video broadcast is carried out according to the synchronization information. The scheme disclosed by the embodiment of the invention not only can detect the low-speed users in real time more accurately, but also greatly simplifies the implementation logic, and improves the detection efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for detecting slow users in network video live broadcast. Background technique [0002] Video network live broadcast has high requirements on network quality. If a smooth playback experience is required, the user's download bandwidth must at least meet the video bit rate requirement. In order to make the playback smoother, in the prior art, the client generally downloads a certain amount of video data in advance before starting to play, so that there is a small cache locally. In this way, when the network quality deteriorates, there is still a part of the video locally. Data can be played, thereby reducing the impact of factors such as network fluctuations on user experience. However, due to the real-time requirements of the live video service, users always want to see the latest picture scene. Therefore, the client can only cache the d...
