Embodiment
In one embodiment, as shown in Figure 1, a kind of method obtaining Internet video broadcasting fluency, comprises the steps:
Step S102, obtains the packet corresponding with Video Applications.
The packet corresponding with Video Applications and Internet video application are transferred to the packet of client by server.The header part of packet includes application type mark usually, such as, for representing the parameter of application type in mime-type(HTTP agreement) attribute tags or the protocol name corresponding with Video Applications.
In one embodiment, the step obtaining the packet corresponding with Video Applications can be specially: obtain packet, extracts the header information of packet, obtains the packet that header information comprises video type mark.Video type mark can be the coded format of video, such as mkv, rmvb, wmv etc.That is, can detect the header information of the packet received, if detect, the head of packet includes video type mark, then obtain this packet or its copy.
Step S104, extract video information according to packet, video information comprises bit rate.
The Video attribute information that video information is namely relevant with video, comprises bit rate, playing duration, file size etc.Video information is stored in the top of file of video file usually.
In one embodiment, the step extracting video information according to packet can be specially: obtain video header data by data cached bag, extracts video information according to video header data.
In the present embodiment, the top of file of the video file that packet or its copy (data length namely preset) extraction by buffer memory predetermined number are transmitted, and video information is extracted from top of file.
Step S106, obtains the connection that packet is corresponding, calculates the transmission rate connected.
By obtaining the size of the data volume transmitted in packet is corresponding in Preset Time connection to calculate the transmission rate of connection.
In the present embodiment, also can the re-transmission in connection or out of order packet be filtered or be arranged before calculating the step of the transmission rate connected.
When network environment is poor, identical packet may retransmit repeatedly, when making to calculate transmission rate, and can with reference to the number of transmissions of identical packet.First the re-transmission in connection or out of order packet are filtered or arranged, and then calculate transmission rate according to filtration and reduced data bag, the actual transfer rate of video content can be obtained, thus improve accuracy further.
Step S108, by comparing bit rate and transmission rate acquisition broadcasting fluency.
By comparing bit rate and transmission rate, broadcasting fluency being marked, embodying broadcasting fluency by the size of scoring.
Such as, if transmission rate is 2048kbps, and bit rate is 1024kbps, then transmission rate is significantly greater than bit rate, can give the scoring that the broadcasting fluency of this connection correspondence is higher; If transmission rate is 1024kbps, and bit rate is 2048kbps, then transmission rate is much smaller than bit rate, and user needs often to suspend buffering can play this video, then can give the scoring that the broadcasting fluency of this connection correspondence is lower.
In one embodiment, the step by comparing bit rate and transmission rate acquisition broadcasting fluency can be specially: the difference and the magnitude relationship that obtain transmission rate and bit rate, calculate according to difference, magnitude relationship and bit rate and play fluency.
Difference is therebetween obtained, magnitude relationship and difference positive and negative by transmission rate being deducted bit rate.In the present embodiment, by the ratio of calculated difference and bit rate, then this ratio is multiplied by the full-time coefficient corresponding with magnitude relationship to obtain scoring corresponding to this connection.
In one embodiment, also can obtaining multiple broadcasting fluency connecting correspondence, on average playing fluency by obtaining after default weights weighted average.
According to information such as domain name, Video type information, geographical location information, bit rate, bandwidth, connection can be divided into polytype, then all broadcasting fluency connecting correspondence in certain type are obtained, then on average fluency is play by the weighted average calculation phase, thus the broadcasting situation of the video entirety of reaction the type.
Such as, can corresponding multiple connections in certain city according to the IP acquisition of information connected, and obtain and the plurality ofly connect corresponding broadcasting fluency, after weighted average, obtain the average broadcasting fluency corresponding with this city.Or can obtain bit rate in the video information of all transmission is the minimum requirements of 1024kbps(720p HD video) connection, and obtain the plurality of broadcasting fluency connecting correspondence, after weighted average, obtain the average broadcasting fluency that 720p HD video is corresponding.
In one embodiment, as shown in Figure 2, a kind of device obtaining Internet video broadcasting fluency, comprises video data acquisition module 102, bit rate acquisition module 104, transmission rate acquisition module 106 and fluency computing module 108, wherein:
