Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the prior art has the following problems: since the relevant information of the test pause is only carried out after the video playback pauses and the user complains, the test result has a lag; and the prior art only The network can be optimized passively according to the user's complaint information, but the network that actually stops and the user has no complaint cannot be effectively optimized, which reduces the user experience

Embodiment 1

[0034] Embodiment 1, a method for obtaining information on pauses in streaming media services, such as figure 1 As shown, the specific implementation is:

[0035] Step 101: the media service starts to transmit data;

[0036] Step 102: Calculate the number of video frames in the terminal cache, which is used when the terminal starts to receive streaming media data in the initial cache N buffer = Σ t V uu * t Calculation; used when playback is paused N buffer = N pause + Σ t V uu * t calculate;

[0037] Step 103: When N buffer >=N play , that is, when the amount of data in the buffer is greater than or equal to the amount of data required for playback, enter step 104, otherwise enter step 10...

Embodiment 2

[0045] Embodiment 2, on the terminal, the video playback rate can be directly determined from the terminal; on the streaming media server side, the video playback rate can be directly determined from the streaming media server, because usually the sending rate of the server and the video playback rate are the same; if The playback rate of the video cannot be obtained directly, and the second embodiment of the present invention provides a method for estimating the playback rate of the video:

[0046] Taking the estimation of the video playback rate by an intermediate node as an example, the intermediate node may be a network control network element such as a radio network controller (RNC, Radio Network Controller), or a base station controller (BSC, Base Site Controller). After the streaming media service is established, the server needs to encode the video source and send streaming media information. The intermediate node counts the total number of video frames received by the...

Embodiment 3

[0052] In the third embodiment, the air interface transmission rate is the rate at which the terminal actually receives data. In this embodiment, a period may be set, and the terminal acquires the air interface transmission rate according to the period. This embodiment provides a method for estimating the air interface transmission rate, which is similar to the method in the second embodiment, except that the air interface transmission rate does not take the maximum value of the calculation result but takes the real-time value. Because the air interface transmission rate is a value that changes in real time, in this embodiment, the air interface transmission rate is set to be acquired periodically to ensure timely acquisition and achieve a more accurate purpose.

[0053] On the basis of the first embodiment, the second embodiment and the third embodiment respectively provide several acquisition methods for the video playback rate and the air interface transmission rate; it is ...

Abstract

The embodiment of the invention discloses a method used for obtaining stream media service stopped information and a device thereof. Taking the embodiment of the invention as an example, after the stream media service is set up, air interface transmission speed rate and media broadcast speed rate are obtained; data quantity in the buffer memory of a computing terminal is calculated according to the air interface transmission speed rate and the media broadcast speed rate; the stopped information is obtained when the data quantity memorized in the buffer memory is equal or less than the critical data quantity. The method used for obtaining the stream media service stopped information and the device thereof has the advantages that the stopped information generated during the broadcasting process of the stream media service can be obtained in real time, and references for the dynamic adjustment of network parameter and network optimization can be provided; in addition, the whole network can be monitored by the device, the optimization range is wider, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for acquiring pause information of a streaming media service. Background technique [0002] The streaming media service is a service in which a terminal plays multimedia data while downloading. Taking the video media business as an example, its biggest feature is that the user can start playing the content before all the content is downloaded. The advantage brought by this is that the user does not have to wait for a long download time, and only needs to download the first section of data to watch, and then the subsequent data will be downloaded to the terminal cache in turn, thereby maintaining the continuity of playback. During the playback of the video, there may be pauses, which will reduce user satisfaction. [0003] The current solution is to test and verify the relevant network that issued the complaint after media playback pauses and c...
