Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 is a flow chart of a short video APP using perceptual evaluation method according to an embodiment of the present invention. Referring to fig. 1, an embodiment of the present invention provides a short video APP usage perception evaluation method, which specifically may include the following steps:

step 101, a TCP code stream of a download request of each video slice is obtained.

The embodiment of the invention is described by taking a server as an execution main body. The short video APP can refer to a short video APP based on MP4 format, in practical application, when a user uses a short video APP client to play MP4 video online, the client can request corresponding video information to a server, the server can respond to related information of the request for issuing video, the client can initiate a resource downloading get request according to the obtained video downloading address, and the server can respond to the resource request message to send corresponding video data to the client. When the video data received by the client exceeds the initial buffer threshold, the client can start playing the video.

Fig. 2 is a schematic diagram of a video playing signaling flow of a short video APP using a perceptual evaluation method according to an embodiment of the present invention. Referring to fig. 2, before video play, a terminal installed with a short video APP client can be controlled to complete a radio access procedure with an access network, an attachment procedure with a core network, and a packet data protocol (Packet Data Protocol, PDP) activation procedure with the core network.

When a user uses a short video APP client installed on a terminal, the terminal may initiate a DNS query to a domain name system (Domain Name System, DNS) which may send DNS responses to the terminal in response to the DNS query.

After completing the DNS query procedure, the terminal may send a synchronization sequence number (Synchronize Sequence Numbers, SYN) to a direct Provider (SP) (i.e., server) of the mobile internet Service content application Service, and the SP may send a syn_ack (Acknowledge character, acknowledgement character) to the terminal in response to the SYN. The terminal may then send ACK and GET download requests to the SP, the SP may REPLY to REPLY 200 OK and the corresponding video slice DATA HTTP DATA, and the terminal may receive the video slice DATA issued by the SP, thereby completing the TCP link establishment, GET request and return processes.

After completing the preparation before video playing, the terminal may send SYN to the SP, the SP may send syn_ack to the terminal in response to SYN, and the terminal may reply ACK to the SP, thereby completing the TCP connection establishment procedure.

After establishing the TCP connection, the terminal may send a GET download request to the SP, and the SP may send REPLY 200 OK and video slice DATA HTTP DATA to the terminal in response to the download request. After the terminal sends LAST HTTP REPLY DATA to the SP, the TCP connection may be torn down.

The short video APP can buffer a plurality of subsequent video slices in advance in the background when the current video is played. Because of the presence of buffering, a distinction can be made between buffered and uncached video slices being played (i.e., downloaded while playing) when making a perceived-as-good determination.

When the user slides the terminal window to the next short video, the user can start playing the cached video slice, and can initiate a downloading request again, and the rest video slices not cached in the video or slices of other later videos are downloaded by using a breakpoint continuous transmission mode, so that the server can acquire the TCP code stream of the downloading request for each video slice.

And 102, comparing byte start-stop position Range fields among each video slice carried by the TCP code stream, and judging the use perception of each video slice.

Specifically, the Range field may be carried by the TCP code stream corresponding to each video slice, and the Range field carried by the TCP code stream corresponding to the previous video slice may be compared with the Range field carried by the TCP code stream corresponding to the next video slice, so as to determine the play status of each video slice, and determine the usage sense of each video slice.

Step 103, evaluating the short video APP usage perception based on the usage perception of each video slice.

The same video source can be divided into at least two video slices for transmission and downloading, the actual use perception situation of a user can be known by judging the use perception of each video slice, statistical analysis is carried out based on the use perception of each video slice, and the use perception of the short video APP can be evaluated.

In the embodiment of the invention, after the TCP code stream of the downloading request of each video slice is obtained, the use perception of each video slice is judged by comparing the Range field between each video slice carried by the TCP code stream, and the use perception of the short video APP is evaluated based on the use perception of each video slice, so that the use perception of the short video APP service can be accurately evaluated from the network side by only collecting the TCP code stream, the landing is simple, thereby being beneficial to monitoring the play condition of the short video APP in real time and improving the network service quality.

In an alternative embodiment, the step 102 may comprise the following sub-steps S11-S12:

step S11, recording XDR ticket in detail for each service, comparing the Range starting value carried by TCP code stream in the current XDR ticket with the Range ending value carried by TCP code stream in the last XDR ticket;

And a substep S12, judging the use perception of the video slice corresponding to the current XDR ticket according to the comparison result.

The TCP code stream requested by each video slice get may be an XDR ticket, multiple XDR tickets may be obtained, and for each XDR ticket, a Range start value carried by the TCP code stream in the current XDR ticket may be compared with a Range end value carried by the TCP code stream in the previous XDR ticket, so as to determine a usage sense of the video slice corresponding to the current XDR ticket.

Specifically, the get request content of the video fragments of the same video source can carry the same main uniform resource identifier (Uniform Resource Identifier, URI) information, the TCP data stream can carry Range keyword information, and the form can be a Range bytes AA-BB field, where AA can represent a byte position of a start of a slice (i.e., a Range start value), and BB can represent a byte position of an end of the slice (i.e., a Range end value). Video slices of the same video source may be defined as a group of video slices. The Range content of the video slice group of the same video source is sequenced, for example, a 3145727 byte-sized video can be divided into 3 video slice downloads, then the first slice Range: 0-1048575, second slice Range: 1048576-2097151, third slice Range:2097152 to 3145727.

In the embodiment of the invention, the use perception of each video slice can be judged by comparing the Range starting value carried by the TCP code stream in the current XDR ticket with the Range ending value carried by the TCP code stream in the last XDR ticket, and the landing is simple, thereby being beneficial to monitoring the play condition of the short video APP in real time and improving the network service quality.

In an alternative embodiment, the substep S12 may include the following substeps S121-S123:

sub-step S121, if the Range start value carried by the TCP code stream in the current XDR ticket is equal to the Range end value carried by the TCP code stream in the last XDR ticket, marking the current XDR ticket as a quality XDR ticket.

Specifically, when the video is normally played, the Range of the get request is not changed, if the Range start value (AA) of the current XDR ticket is equal to the Range end value +1 (bb+1) of the last XDR ticket, the current XDR ticket is the normal play XDR ticket, and the current XDR ticket can be marked as a quality XDR ticket.

For example, if the Range contents of Http get requests of the same group of video slices are in sequence, namely, the Range of the first slice is AA-BB, the Range of the second slice is BB+1-CC, the Range of the third slice is CC+1-DD, …, and so on, the TCP code stream of each video slice of the same video source is a normal playing XDR ticket, namely, a quality excellent XDR ticket.

And sub-step S122, if the Range start value carried by the TCP code stream in the current XDR ticket is smaller than the Range end value carried by the TCP code stream in the last XDR ticket, marking the current XDR ticket as a quality difference XDR ticket.

Specifically, when the video is played in a pause, the Range of the get request is changed; when serious clamping occurs, the TCP data stream is disconnected, a get request for the video slice is restarted, and the Range carried by new get request information is that AA in bytes is equal to the downloaded data position of the video slice with clamping, BB is the same as the clamping slice, for example, clamping video slicing Range: bytes 100-200, which are not completely downloaded, are blocked after 100-150 is downloaded, and 50bytes are not completely downloaded, then the newly downloaded video clip is Range: bytes 151-200. If the Range start value (AA) of the current XDR ticket is smaller than the Range end value +1 (BB+1) of the last XDR ticket, the current XDR ticket is a cartoon playing XDR ticket, and the current XDR ticket can be marked as a quality difference XDR ticket.

And sub-step S123, if the Range start value carried by the TCP code stream in the current XDR ticket is larger than the Range end value carried by the TCP code stream in the previous XDR ticket, calculating the average playing code rate of the video slice and the downloading rate of the video slice, comparing the average playing code rate of the video slice and the downloading rate of the video slice, and judging whether the current XDR ticket is a quality XDR ticket or not.

Specifically, when fast forward occurs (for example, a user drags the playing progress to the outside of the buffer area), the Range of get requests of the same group of video slices will change, and instead of going in sequence, the get requests directly download video slices of the fast forward position (the Range of the fast forward video slice: DD-EE, the start value DD of which is greater than the end value of the previous video slice), and the video slices of this case belong to the uncached and play-while-play mode. If the Range starting value (AA) of the current XDR ticket is larger than the Range ending value +1 (BB+1) of the last XDR ticket, the current XDR ticket is fast forward for playing the XDR ticket, the average playing code rate of the video slice and the downloading rate of the video slice can be calculated, and whether the downloaded video slice meets playability or not is judged by comparing the average playing code rate of the video slice and the downloading rate of the video slice, so that whether the video slice is blocked or not is judged, and whether the current XDR ticket is a good XDR ticket is judged.

In the embodiment of the invention, which play state of the downloaded video slice is in normal play, fast forward play and cartoon play can be judged according to the data transmission mode characteristics of the TCP code stream, and the XDR ticket is judged to be the excellent XDR ticket or the poor XDR ticket by combining the average play code rate of the video slice, so that the use perception of the short video APP service can be accurately estimated from the network side only by collecting the TCP code stream, the landing is simple, the real-time monitoring of the play condition of the short video APP is facilitated, and the network service quality is improved.

In an alternative embodiment, said comparing said video slice average playback rate to said video slice download rate, determining whether said current XDR ticket is a quality good XDR ticket, comprises: if the average playing code rate of the video slice is larger than the downloading rate of the video slice, marking the current XDR ticket as a quality difference XDR ticket; and if the average playing code rate of the video slice is smaller than or equal to the downloading rate of the video slice, marking the current XDR ticket as a quality XDR ticket.

If the current XDR ticket is the fast forward playing XDR ticket, the video slice playing code rate and the video slice downloading rate can be calculated, the video slice playing code rate and the video slice downloading rate are compared, and whether the current XDR ticket is the excellent XDR ticket or the poor XDR ticket is judged according to the comparison result. Specifically, if the average playing code rate of the video slice is greater than the downloading rate of the video slice, the current XDR ticket can be marked as a quality difference XDR ticket; if the video slice average playing code rate is less than or equal to the video slice downloading rate, the current XDR ticket can be marked as a quality excellent XDR ticket.

In an alternative embodiment, the calculating the average playing code rate of the video slice includes: reading the total size of the video from a Content-Range field which is carried by the TCP code stream and used for recording the start and stop positions of the slice and the length of the video Content; reading media playable time length from a position, which is backwards shifted by 16 bits, of an mvhd key field which is carried by a TCP code stream of a first video slice and is used for describing media sharing information, and carrying out binary conversion on the media playable time length to obtain video playable time length; and calculating the average playing code rate of the video slice based on the total video size and the playable duration of the video.

Specifically, the size of the video slice can be obtained through a Content-Range:bytes AA-BB/CC field in a TCP code stream of the video slice get request, wherein AA can represent the byte position of the start of the slice, BB can represent the byte position of the start of the slice, CC can represent the total size of the video, and the total size of the video can be obtained by reading a CC field in the Content-Range field.

In the first video fragment of each video, that is, the fragment of the Range starting from 0, the first two payload packet positions of the downstream after the get request may have mvhd key fields, the mvhd key fields may be shifted back by 16 bits to read the 17 th to 20 th bit information, the 17 th to 20 th bit information is duration (i.e., media playable duration), the media playable duration is a 16-ary codeword, and the media playable duration may be converted into decimal to obtain the video playable duration. For example, assuming that the duration is 00 00 & lt 89 & gt2 a, a conversion to decimal system can result in 35114 ms =35s, and 35s is the video playable duration.

The "video total size bytes" 8/"video playable duration ms" is calculated, and the "video slice average playing code rate kbps" can be obtained.

In the embodiment of the invention, the average playing code rate of the video slice can be calculated based on the TCP code stream characteristics, so that the use perception of the short video APP of the user is evaluated by combining the average playing code rate of the video slice.

In an alternative embodiment, the calculating the video slice download rate includes: calculating the difference value between the Range end value carried by the TCP code stream and the Range start value to obtain the video slice size; calculating the difference value between the last HTTP content packet time carried by the TCP code stream and the first HTTP content packet time of the get request to obtain the last HTTP content packet time delay; and calculating a video slice downloading rate based on the video slice size and the last HTTP content packet delay.

Specifically, the size of a video slice, i.e. "video slice size" =bb-AA, may be obtained by Range: bytes AA-BB of the video slice of each get request.

The video slice download duration, i.e. "last HTTP content packet delay", may be obtained by subtracting the "last HTTP content packet time" of the video slice TCP stream from the "first HTTP content packet time" of the get request.

Calculating the 'video slice size bytes' 8/'last HTTP content packet delay ms', the 'video slice download rate kbps' can be obtained.

Fig. 3 is a schematic diagram of determining a delay of a short video APP using a perceptual evaluation method according to an embodiment of the present invention. Referring to fig. 3, a TCP chaining response delay may be determined based on a SYN transmission time and a syn_ack response time; the TCP link establishment acknowledgement delay may be determined based on the syn_ack response time and the ACK transmission time; the delay from the successful TCP link establishment to the first transaction request can be determined based on the ACK transmission time and the GET request transmission time; the first transaction request to its first response packet delay and the first HTTP response packet delay may be determined based on the GET request send time and the TCP No.1 (200 OK) receive time; the time delay of the last HTTP content packet may be determined based on the GET request send time and the TCP No.3 receive time; the delay of the last ACK acknowledgement packet may be determined based on the GET request transmission time and the ACK transmission time.

In the embodiment of the invention, based on the TCP code stream characteristics, the video slice downloading rate can be calculated, so that the average playing code rate of the video slice is compared with the video slice downloading rate to evaluate the use perception of the short video APP of the user.

In an alternative embodiment, said evaluating short video APP usage awareness based on said usage awareness of each video slice comprises: calculating the ratio of the XDR call quantity to the total XDR call quantity to obtain the short video play cartoon rate; the short video play katon rate is used for evaluating short video APP usage awareness.

Specifically, the TCP code stream of each video slice is an XDR ticket, after all DR tickets are marked as excellent XDR tickets or poor XDR tickets, the short video playing click-through rate can be obtained by calculating the proportion of the poor XDR ticket, that is, the ratio of the poor XDR ticket to the total XDR ticket is calculated, so as to obtain the short video playing click-through rate, which is used for evaluating the usage perception of the short video APP.

In the embodiment of the invention, the monitoring and analysis of the network index can be performed through multi-dimensional aggregation of the user dimension, the cell dimension, the branch company, the whole network and the like. For the user dimension, the short video play katon rate of a certain user when using the short video APP can be calculated, the method is applied to the index condition of monitoring the short video APP play of a single (multiple) user in real time, the implementation of a related network optimization scheme is guided, the user is ensured to obtain good perception in real time, and meanwhile, the method can be also used for the statistical analysis of the short video APP application of the single (multiple) user, and the short video APP service use perception of multiple dimensions of the user or the network and the like is evaluated.

In an alternative embodiment, the obtaining the TCP stream of the download request of each video slice includes: acquiring a TCP code stream sent by a client; and identifying the TCP code stream of the downloading request of each video slice from the TCP code streams sent by the client according to the Http get request format characteristic, the Http return status Content, the Content-Type field Content for recording the Content Type and the Host address.

The short video APP can download video slices by using TCP and HTTP protocols, adopts a GET request form, downloads MP4 video files with the video format of ". MP4" by using a breakpoint continuous transmission mode, and transmits the video in a slice segmentation form.

The server can use the following 4 parts of TCP and HTTP code stream content characteristic combinations to identify the video slices of the short video APP. When the server receives the TCP stream sent by the client, if the Http GET request information format in the TCP stream is "GET/ksc 1/… … MP4? … … ", http return status Content is 206 or 200 ok, content-Type field Content is video/mp4, and the Host address is in the format of a.yxmgs.com or a.a.etoo.com (representing a different prefix, such as bdskmov.a.yxmgs.com, representing bdskmov), then the TCP stream is the TCP stream of the download request for the video slice.

In the embodiment of the invention, based on the code stream characteristics of the TCP and HTTP related protocols, the TCP code stream of the video get request can be accurately identified from the TCP code stream sent by the client, so that the use perception of the short video APP service is evaluated based on the TCP code stream.

Fig. 4 is a schematic diagram of a video slice sensing determination and quality difference positioning delimitation flow of a short video APP using a sensing evaluation method according to an embodiment of the present invention.

Referring to fig. 4, after the Http request is successful, if the Range start bit in the same Http request is equal to the Range end byte bit +1 of the last Http request, the video slice of the Http request is a video slice that normally plays without any clip, or is a video slice that is downloaded while playing, and the XDR ticket is a quality XDR ticket.

If the Range start bit in the Http request is greater than the Range end byte bit +1 of the last same Http request, the video slice of the Http request is a video slice (unbuffered area) for fast forward play, if the average play code rate of the video slice is less than or equal to the download rate of the video slice, the XDR ticket is a quality XDR ticket; if the average playing code rate of the video slice is larger than the downloading rate of the video slice, the XDR ticket is a cartoon playing XDR ticket, namely a quality difference XDR ticket.

If the Range start bit in the Http request is less than the Range end byte bit +1 of the last same Http request and is the same as the Range end bit in the last same Http request, the video slice of the Http request is a video slice played by a cartoon, and the XDR ticket is a quality difference XDR ticket.

In the TCP establishment stage, if the wireless time delay is greater than 144ms and the core time delay is greater than 47ms, it can be determined that the quality difference XDR ticket is caused by the wireless and core sides; if the wireless time delay is greater than 144ms and the core time delay is less than or equal to 47ms, the quality difference XDR ticket can be determined to be caused by the wireless side; if the wireless time delay is less than or equal to 144ms and the core time delay is greater than 47ms, it can be determined that the bad XDR ticket is caused by the core side.

In the HTTP connection stage, if the wireless time delay is less than or equal to 144ms and the core time delay is less than or equal to 47ms, judging whether the uplink RTT time delay is more than 26ms. If the uplink RTT time delay is greater than 26ms and the downlink RTT time delay is greater than 84ms, it can be determined that the quality difference XDR ticket is caused by the wireless side and the core side (Http phase); if the uplink RTT delay is greater than 26ms and the downlink RTT delay is less than or equal to 84ms, it may be determined that the quality difference XDR ticket is caused by the core side (Http stage).
