Disclosure of Invention
The embodiment of the application provides a video processing method and network equipment to solve the problem that deviation is easily generated in video quality evaluation caused by errors existing in video blocking calculation.
In view of the above, a first aspect of the present application provides a video processing method, in which a network device serving as a terminal and a server first obtains an Identification (ID) and video information of a video from a video message communicated between the server and the terminal; then, acquiring the video pause information sent by the terminal to the server, wherein the video pause information is provided by the terminal, the video is played by the terminal through a player, so that the video pause information is accurate, then the network equipment associates the pause information with the ID of the video, namely the pause information can be corresponding to the specific video, and finally, the network equipment determines the quality information of the video according to the video information and the pause information.
The method comprises the steps of firstly obtaining the ID and the video information of the video, then directly receiving the pause information from the terminal, then associating the ID of the video with the pause information, and finally determining the quality information through the video information and the pause information.
In some embodiments, the network device may obtain the ID and the video information of the video from the video message communicated between the server and the terminal by: firstly, network equipment acquires the ID and the video code rate of a video from a video response message, and then the network equipment can simulate the video to play the video according to a video data message and the video code rate so as to determine the initial buffering duration and the downloading rate of the video, wherein the video data message is the video message sent to the terminal by the server. The video response message is a video message sent to the terminal by the server. It can be seen that the simulated play behavior only determines the initial buffering time length and the download rate of the video, the initial buffering time length is the time length required by loading the video from the time of connecting to the server to the time when the video can start to play, and the video information can be provided to the network device so that the network device can judge the quality information of the video.
In some embodiments, the method further comprises: and determining the number of times of clamping and the time length of clamping from the clamping information. The time and the time length of the pause can be determined from the pause information sent from the terminal to the server, so that the subsequent judgment of the quality information of the video is facilitated.
In some embodiments, the determining, by the network device, the quality information of the video may be determining the quality information of the video according to the initial buffering duration, the downloading rate, and the pause information of the video corresponding to the video ID. The video quality can be judged according to the video information, and the judgment process can be carried out by adopting some video quality evaluation algorithms, so that the video quality can be accurately judged.
In some embodiments, the Quality information includes a Quality level of the video, Key Quality Indicators (KQI) indicating the level of the video information, and Key Performance Indicators (KPI) indicating the video network Quality level (e.g., the number of clicks and the length of clicks). The quality information can exhibit various qualities such as a KQI index for video information and katon information of a video, and a KPI index for indicating quality in a video network, which can reflect the overall quality of a video from different perspectives.
In some embodiments, the network device outputs quality information corresponding to the video ID. The output can be that the quality information is directly displayed, namely, the quality grade, the KQI and the KPI index of the video are directly displayed, the quality grade is overall evaluation, and the KQI and the KPI are evaluation for the angle of the video which is more detailed.
In some embodiments, the network device may further output quality information corresponding to the area, the network element, the terminal, or the video website by displaying the quality information corresponding to the video ID. The quality information is displayed according to different angles, for example, the information displayed according to the terminal angle and the angle of the video website can be different, for example, the priority ranking is performed according to different importance degrees of the parameters concerned by the terminal and the video website, and the parameters required by the user can be acquired at different angles through the method.
In some embodiments, the network device may associate the morton information with the ID of the video by: and associating the pause information with a characteristic field in an HTTP (hyper text transport protocol) data frame used for transmitting the video. Since these characteristic fields are different for different terminals, and the data frames received in the same time period are not necessarily data frames between the same terminal and the server, it is necessary to perform a distinguishing association in order to accurately monitor the video playing condition of each terminal.
In some embodiments, the network device may associate the morton information with the ID of the video by: associating the morton information with IP feature information, wherein the IP feature information comprises at least one of an IP address, an IP-ID and a Transmission Control Protocol (TCP) timestamp.

Detailed Description
The embodiment of the application provides a video processing method and network equipment, which can determine more accurate video quality information through acquiring frequency information and accurate pause information.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments.
The following are detailed below.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings (if any) are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein.
In a video transmission mode based on HTTP protocol, please refer to fig. 1, where fig. 1 is a schematic diagram of video transmission based on HTTP, where the video transmission mode includes a server and a plurality of terminals corresponding to the server, a network device for monitoring video is further provided between the server and the terminals, all data sent by the terminals to the server can be monitored by the network device, and a process of the terminals playing the video is as follows: when the player in the terminal is connected to the video to be played, buffering is performed for a period of time, that is, the terminal receives a part of video data from the server first and uses the part of video data as buffer data of the player, and the video data received from the server is continuously injected into the buffer during the continuous playing of the video.
The network device calculates the video morton in the playing mode, and the adopted mode of simulating the players is that the players on different terminals are different, the types of the players are many, the playing parameters of different players are different, and the network device cannot simulate all the players, so that deviation can be generated between simulation and actual playing process of some players, and the calculated morton information is incorrect.
In view of the above, a video processing method provided by the embodiments of the present application is to solve the above problem, please refer to fig. 2, where fig. 2 is a diagram of an embodiment of a video processing method according to the embodiments of the present application, the method includes a terminal, a network device, and a server, and a specific process (from the beginning, establishing a video connection) may include:
201. and the terminal sends a video request message to the server.
When a user wants to watch a network video, the terminal sends a video request message to the server when the user is on a video page, so that a player on the video page can be connected to the server and play a corresponding video.
202. And the server sends a video response message to the terminal.
After receiving the video request message, the server generates a response and sends a corresponding video response message to the terminal.
203. And the network equipment acquires the ID and the video code rate of the video from the video response message.
The video request message and the video response message can both carry video ID, and the video response message can carry video code rate, so one way is to extract the video ID and the video code rate from the video response message, and certainly, the video ID and the video code rate can also be extracted from the video request message and the video response message.
204. And the server sends the video data message to the terminal.
After the video connection is established, the server sends a video data message to the terminal, and in the process of sending the video data message, the terminal does not immediately start playing videos, but takes video data received within a period of time as a buffer area.
205. The network equipment calculates the initial buffering time length and the downloading rate of the video through the analog player.
The network device can simulate a player to calculate the initial buffering time and the downloading rate of the video, and the initial buffering time is only the receiving time of the video data which is judged to be used as the buffer area and is only related to the downloading rate and the video code rate, so that the difference between the calculated initial buffering time and the initial buffering time calculated by the terminal is very small, and the downloading rate can be obtained only by monitoring the video data message.
206. And when the player of the terminal judges that the data in the buffer area is lower than the normal playing threshold value, generating pause information.
The video data in the buffer area consumed by the playing of the video may be faster than the video data received from the server due to the influence of the video code rate, which may result in less video data in the buffer area, when the video data in the buffer area is smaller than the normal playing threshold, the player may consider that the video data in the buffer area is not enough to support continuous playing, at this time, video pause may occur, and the terminal may generate pause information at this time, where the pause information includes the number of times of pause within a period of time and the pause duration from the beginning of pause to the end of pause each time of pause.
207. And the terminal sends the card pause information to the server.
After the terminal generates the card pause information, the card pause information is sent to the server.
208. The network device determines the number of times of the pause and the length of the pause from the pause information.
After the network device acquires the pause information, the network device can acquire the pause times and pause time from the pause information, and because the pause time of each pause is not necessarily the same, and the pause times in a period of time are not necessarily the same, the pause times and the pause time need to be recorded respectively.
209. The network device associates the morton information with the ID of the video.
After the pause information is acquired, the pause information is associated with the ID of the video, and as the pause information is generated by one terminal and the network equipment is connected to one or more terminals, under the condition of a plurality of terminals, the pause information needs to be distinguished and processed and is associated with the pause information in the mode of the ID of the video, so that when a plurality of terminals play a plurality of videos or one terminal plays one video, accurate distinction can be carried out.
It should be noted that there are two ways of associating the morton information with the feature field in the data frame of the HTTP protocol, and the feature field may be HOST, Uniform Resource Locator (URL), or HTTP header. The fields are characterized in that different terminals or different messages sent by the same terminal can be distinguished, wherein the HOST comprises an IP address and a HOST name, the URL is used for identifying the website of the site for acquiring the video message, and the information carried in the HTTP header field can also uniquely identify the video website or the terminal.
Another is to associate the morton information with IP feature information including at least one of an IP address, an IP-ID, and a TCP timestamp. Similar to the association of characteristic fields in data frames, an IP address can uniquely identify a terminal or a server, IP-IDs (Internet protocol-identification) are different in each video data message and can be used for distinguishing video data messages of different videos of the terminal, TCP timestamps are similar, and the TCP timestamps in the video data sent by a TCP protocol each time are different and can distinguish different videos of the terminal.
210. And the network equipment determines the quality information of the video according to the video pause information, the initial buffering time and the downloading rate.
The network device determines the quality information of the video according to the previous video blocking times, blocking duration, buffering duration, video code rate and download rate, and certainly may have some video parameters, such as video resolution for showing video image definition and video frame rate for showing video fluency, and certainly may also include video watching duration, and the corresponding quality information can be calculated through some video quality evaluation algorithms according to these parameters.
The quality information may include a quality grade, i.e. a score given to the video, and of course, there may also be a key quality indicator KQI for indicating the grade of the video information, such as performing a comprehensive analysis on a video bitrate, a video frame rate and a video resolution to give a corresponding grade, and there may also be a key performance indicator KPI for indicating a video network quality grade, such as a number of times of katton and a length of katton time equal to a network quality-related parameter, and performing the analysis to give the network quality grade.
For example, the corresponding quality information is calculated by adopting a U-vMOS algorithm or a vMOS algorithm. The U-vMOS algorithm and the vMOS algorithm are described below.
First, U-vMOS is introduced:
the U-vMOS aims to construct a unified cross-screen, cross-network and multi-service objective video experience standard system, and reflects the quality of video service experience through objective video experience evaluation standard perception.
The evaluation model of the U-vMOS is mainly divided into three parts, the U-vMOS is a comprehensive score, and the U-vMOS further has three quality scores (sQuality), interaction experience scores (sInteraction), and viewing experience scores (sView) of the sub-videos, and the specific evaluation granularity, i.e. the score, can refer to the following table 1:
TABLE 1
The method comprises the following steps of (1) monitoring a real-time sView scoring principle under a real-time monitoring scene:
a stuck event: a pause event is formed from the beginning of the picture entering a playing waiting state to the end of the picture resuming playing;
a clamping interval: the interval event from the end of one time of clamping to the beginning of the next clamping is a clamping interval;
successive stuck events: the multiple consecutive stuck events are one consecutive stuck event. The intervals between the jams are smaller than a certain fixed time length, and the jams are judged to be continuous.
The vMOS is described below.
The vMOS is an index weighted average algorithm, namely, a plurality of indexes can be subjected to quality scoring through the weighted average algorithm.
vMOS is typically classified into 5 classes as shown in table 2 below:
TABLE 2
| Grade of experience | MOS value |
| Superior food | The vMOS value is 4.5-5 |
| Good wine | The vMOS value is 3.5-4.5 |
| In | The vMOS value is 2.5-3.5 |
| Next time | The vMOS value is 1.5-2.5 |
| Difference (D) | vMOS value of 0-1.5 |
The calculation process of vMOS is to multiply the vMOS value of a certain KPI by its weight, namely mos (KPI) weight, and then add all the mos (KPI) weight to obtain a comprehensive vMOS value, for example, if there are 5 KPI, the vMOS value will be calculated as:
MOS＝MOS(KPI1)*WEIGTH1+MOS(KPI2)*WEIGTH2+MOS(KPI3) *WEIGTH3+MOS(KPI4)*WEIGTH4+MOS(KPI5)*WEIGTH5
the KPIs may be various types of parameters of the video, for example, parameters for the video, video resolution, video code rate, video frame rate, video buffering duration, video downloading speed, video blocking duration, video blocking times, and the like for the video network layer may be used as KPIs in the vMOS calculation process.
211. And the network equipment outputs the quality information of the video corresponding to the video ID.
After the calculation of the quality information of the video is completed, the quality information can be output, for example, output to a certain display device for display.
It should be noted that, during output, output can be performed at different angles, and it is easy to focus on a region or a network element, and network quality may be concerned more, and then the KPI columns may be presented at the top and in detail, and the remaining quality levels and KQI are displayed after being arranged, and if the quality levels of videos are concerned more for users or video websites, quality levels or KQI columns may be presented at the top and in detail, if the video websites can show contrast between different video resources, the method can present video quality at different angles, and different requirements are met.
