Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a method for acquiring network video playing information of a smart television according to a first embodiment of the present invention includes:
step S100, obtaining the data packet transmitted and received through the currently operating network interface from the link layer.
Specifically, after the television system is started, the current network access mode is detected, so as to monitor a working network port corresponding to the network access mode, such as an ethernet port eth0, a wireless network wlan0, and the like. The detection of the network access mode, and the acquisition of data packets transmitted and received via the currently operating network interface from the link layer, need to exist all the time during the operation of the television system, and when the change of the network access mode is detected, the monitored working network port needs to be changed correspondingly.
And copying and analyzing part of data packets passing through the current working network port from a TCP/IP link layer. Each packet contains source address, source port, destination address and destination port information.
Step S200, when the data packet is a request packet and the data in the request packet includes a video address, acquiring and storing first playing information of a currently played video according to the data packet, wherein the first playing information includes a playing start time and a video address.
After the data packet is obtained, it is first determined whether the source address of the data packet is the local address, if so, the data packet may be a request packet for video playing, and if not, the data packet may be a response packet.
If the video address (i.e. UR L address) in the request packet has a field of ". m3u 8.
From the above, when the request packet passing through the working network port is obtained from the link layer, the play start time and the video address can be obtained.
Step S300, when the data packet is a response packet, second playing information of the currently played video is obtained according to the response packet and stored, and the second playing information comprises the playing state of the currently played video and/or the received data length.
Specifically, when the source address is not the local address, the packet obtained from the link layer is a response packet. The request from the intelligent television client to the server side and the response from the server side to the intelligent television client are realized by a session containing data streams in two directions, and all the sessions are started from the request. The flags of the two flows of the same session are address information, the source addresses and the destination addresses of the request packet and the response packet are opposite, and if the request address is 192.168.029.147.44345-192.168.029.016.08118, the response address is 192.168.029.016.08118-192.168.029.147.44345. Whether the same session is conducted between the intelligent television client and the server side or not can be known by looking at the source address and the destination address of the request packet and the response packet.
The method comprises the steps that when a smart television client sends a request packet for obtaining an H L S playlist to a server, an H L S playing session is created and added to a session queue to wait for a response of the server, when the server receives the request packet, a response packet is returned to the smart television client, the smart television client analyzes the response packet to obtain the H L S playlist, after the smart television client obtains the H L S playlist, a session is created for each subsequent media stream segment obtaining request to detect the playing state, when the server receives the media stream segment obtaining request, the server returns a response packet to the smart television client, and the response packet is analyzed to obtain the media stream segments to be played.
When the smart television client sends a request for obtaining an H L S playlist to the server, a corresponding response packet is obtained at a link layer, the response packet is stored, a media URI list and an information label are obtained after the response packet is analyzed, and the information label comprises the standard playing time length and the data length of each media stream segment.
The method comprises the steps that the server side sends media stream segments to the smart television client side according to a URI list in an H L S playlist, and the server side sends a request for obtaining the media stream segments to the server side.
From the above, the received data length and the stuck condition can be obtained according to the response packet obtained from the link layer and passing through the working network port.
Step S400, when the end of the playing of the current playing video is detected, the playing end time is recorded, and the first playing information, the second playing information and the playing end time are sent to a server.
Specifically, playing each media stream segment received in sequence at the smart television client, and recording the playing ending time when the end of playing of the currently played video is detected. The first playing information obtained according to the request packet, such as the recorded playing start time and the video address, the second playing information obtained according to the response packet, such as the received data length, the pause times and the duration, and the recorded playing end time, are sent to a server for data statistics, and the server can analyze the network video playing quality of the smart television according to the information, such as the most browsing times of which website the user browses, whether pause frequently occurs when the video resources are obtained from the website, the highest attention degree of which video resources the user pays attention to, and the like.
In the technical scheme provided by the invention, all video applications are interacted with a server based on the internet as a client when playing programs, and data is acquired by sending a request waiting response according to the operation of a user, so that a data packet can be captured from a link layer of a monitored network port, and if a request packet for starting video playing is acquired, playing information such as playing starting time and video address is recorded; when a response packet corresponding to the request packet is captured, the playing state of the currently played video can be acquired according to the response packet, and the received playing information such as the data length and the like is recorded; when the end of the playing is detected, the time of the playing end is recorded, and the playing information and the time of the playing end are organized and packaged into an agreed format to be sent to the server. The collection of the playing information is realized by processing the data packet acquired on the link layer, and the processing of the data packet is simpler, so that the method for collecting the playing information is simple and convenient, and the problem of adapting to various video applications does not exist.
Further, referring to fig. 2, a second embodiment of the method for acquiring network video playing information of a smart television according to the present invention is shown, based on the first embodiment of the method for acquiring network video playing information of a smart television according to the present invention, where the playing status includes a pause duration, and the step of acquiring and storing the second playing information of the currently played video according to the response packet includes:
step S301, analyzing the response packet to obtain analysis data;
step S302, when the analysis data includes an ordered media uniform resource identifier list, acquiring and storing the uniform resource identifier list, the standard playing time length of the media stream segment and the data length in the analysis data.
Specifically, when the smart television client sends a request for obtaining a playlist to the server, the server responds and sends a response packet to the smart television client. The response packet passing through the working network port may be obtained from the link layer, and a copy is made, and after the response packet is analyzed, a media URI list and an information tag may be obtained, where the information tag includes a standard play time and a data length of each media stream segment, which is exemplified as follows:
the smart television client plays a single continuous media stream, the single continuous media stream is composed of a plurality of ordered media stream segments, if the continuous media stream is 500 million, the continuous media stream can be played for 500 minutes in total, the continuous media stream is composed of 250 media stream segments, if the data length of each media stream segment is the same, the data length of the first media stream segment, the second media stream segment to the second hundred and fifty media stream segments is 2 million, and the playing time length (i.e. the standard playing time length) is 2 minutes.
Step S303, when the analysis data includes the media stream segment and the received media stream segment reaches the data length, acquiring the actual playing time length of the received media stream segment;
step S304, when the actual playing time length is longer than the standard playing time length, recording the pause time length of the currently played video.
Specifically, when the smart television client sends a request for acquiring the media stream segment to the server according to the media URI list, the server responds and sends a response packet containing the media stream segment to the smart television client. The response packet passing through the working network may be obtained at the link layer, but the response packet is not stored, but the time used by the smart tv client to completely receive the media stream segment, that is, the actual playing time length, is recorded, for example, as follows:
the method comprises the steps that a smart television client sends a request for obtaining a first media stream segment to a server according to a URI of the first media stream segment in a media URI list, the server sends the first media stream segment to the smart television client according to the request, because the first media stream segment is 2 million, when the smart television client receives 2 million of data, the fact that the first media stream segment is received completely is indicated, the time from sending the request for obtaining the first media stream segment to the fact that the data are received completely is recorded, if the time is used for 3 minutes, because the actual playing time is longer than 2 minutes of a standard playing time, the fact that video playing is blocked is indicated, the blocking time is 1 minute, and the blocking times are added with 1. The final pause number uploaded to the server is the accumulated pause number between the play start time and the play end time.
In order to obtain the standard playing time length and the data length of each media stream segment and the actual playing time length from the time of sending the request for obtaining the media stream segment to the time of receiving the media stream segment in the complete period, only a response packet containing an ordered media uniform resource identifier list and an information tag needs to be stored, and the response packet containing the media stream segment and having a larger occupied space does not need to be stored, so that the memory occupation is reduced.
In this embodiment, the playing state of the currently played video can be determined by the response packet obtained from the link layer through the working network port, and the number of times and duration of the pause and the length of the received data are recorded.
Further, on the basis of the second embodiment, when the data in the request packet includes a video address and the smart tv is in a video playing state, it is determined that the current video playing is finished.
Specifically, when the current H L S playing is in progress, a request for obtaining an H L S playlist with a field of ". m3u 8.
Further, on the basis of the second embodiment, when the data packet is a request packet and the data in the request packet includes a video address, the step of obtaining and storing the first playing information of the currently played video according to the data packet includes:
step S500, when the request packet containing the media uniform resource identifier is not acquired from the link layer within the preset time, the end of the playing of the currently played video is judged.
Specifically, the media stream segment currently downloaded from the server end is consumed, but the request for obtaining the next media stream segment is not continuously received at the link layer, which indicates that the currently playing video playing is also ended. There are two cases where the link layer does not continue to receive a request to retrieve the next media stream segment: first, if all media stream segments have been completely downloaded, it means playing to the end; second, if all media stream segments are not completely downloaded, it may mean that the user actively quits playing.
Further, referring to fig. 3, a third embodiment of the method for acquiring network video playing information of a smart television according to the present invention is based on the first or second embodiment, where the data packet is a request packet, and when data in the request packet includes a video address, the step of obtaining and storing the first playing information of a currently playing video according to the data packet includes:
step S201, when the data packet is a request packet and the data in the request packet includes a video address, determining whether a destination address of the request packet is a preset address;
step S202, when the destination address of the data packet is a preset address, acquiring and storing first playing information of a currently played video according to the data packet.
In particular, since the number of packets passing through a particular portal can be enormous, it is important to set appropriate packet filtering conditions, which would place a significant performance burden on the television system if all packets were detected and could lead to inaccuracies in the detection results.
For the data packet sent from the local address, filtering may be performed according to the destination address and the destination port, for example, the destination port number may be limited to only 80, and so on. According to the filtering condition of the destination address, statistics can be carried out on information of a specific video resource acquisition path, such as the jamming condition of a server provided by Yokoku.
Referring to fig. 4, a first embodiment of the system for acquiring network video playing information of a smart television according to the present invention includes:
a data obtaining module 100, configured to obtain, from the link layer, a data packet transmitted and received through a currently operating network interface.
Specifically, after the television system is started, the current network access mode is detected, so as to monitor a working network port corresponding to the network access mode, such as an ethernet port eth0, a wireless network wlan0, and the like. The detection of the network access mode needs to exist all the time during the operation of the television system, and when the change of the network access mode is detected, the monitored working network port needs to be changed correspondingly.
And copying and analyzing part of data packets passing through the current working network port from a TCP/IP link layer. Each packet contains source address, source port, destination address and destination port information.

the smart television client plays a single continuous media stream, the single continuous media stream is composed of a plurality of ordered media stream segments, if the continuous media stream is 500 million, the continuous media stream can be played for 500 minutes in total, the continuous media stream is composed of 250 media stream segments, if the data length of each media stream segment is the same, the data length of the first media stream segment, the second media stream segment to the second hundred and fifty media stream segments is 2 million, and the playing time length (i.e. the standard playing time length) is 2 minutes.
An actual playing time length unit 303, configured to obtain an actual playing time length of the received media stream segment when the parsing data includes the media stream segment and the received media stream segment reaches the data length;
a pause duration unit 304, configured to record the pause duration of the currently played video when the actual playing duration is greater than the standard playing duration.
Specifically, when the smart television client sends a request for acquiring the media stream segment to the server according to the media URI list, the server responds and sends a response packet containing the media stream segment to the smart television client. The response packet passing through the working network may be obtained at the link layer, but the response packet is stored, and the time used by the smart tv client to completely receive the media stream segment, that is, the actual playing time length, is recorded, for example, as follows:
the method comprises the steps that a smart television client sends a request for obtaining a first media stream segment to a server according to a URI of the first media stream segment in a media URI list, the server sends the first media stream segment to the smart television client according to the request, because the first media stream segment is 2 million, when the smart television client receives 2 million of data, the fact that the first media stream segment is received completely is indicated, the time from sending the request for obtaining the first media stream segment to the fact that the data are received completely is recorded, if the time is used for 3 minutes, because the actual playing time is longer than 2 minutes of a standard playing time, the fact that video playing is blocked is indicated, the blocking time is 1 minute, and the blocking times are added with 1. The final pause number uploaded to the server is the accumulated pause number between the play start time and the play end time.
In order to obtain the standard playing time and the data length of each media stream segment and the actual playing time from the time of sending the request for obtaining the media stream segment to the time of receiving the media stream segment in the complete period, only a response packet containing an ordered media uniform resource identifier list and an information tag needs to be stored, and a response packet containing the media stream segment with a larger occupied space does not need to be stored, so that the memory occupation is reduced.
In this embodiment, the playing state of the currently played video can be determined by the response packet obtained from the link layer through the working network port, and the number of times and duration of the pause and the length of the received data are recorded.
Further, referring to fig. 6, a third embodiment of the system for acquiring network video playing information of a smart television according to the present invention is shown, and based on the second embodiment of the system for acquiring network video playing information of a smart television according to the present invention, the system for acquiring network video playing information of a smart television further includes:
the first end determining module 600 is configured to determine that the current video playing is ended when the data in the request packet includes a video address and the smart television is in a video playing state.
Specifically, when the current H L S playing is in progress, a request for obtaining an H L S playlist with a field of ". m3u 8.
Further, referring to fig. 7, a fourth embodiment of the system for acquiring network video playing information of a smart television according to the present invention is shown, and based on the second embodiment of the system for acquiring network video playing information of a smart television according to the present invention, the system for acquiring network video playing information of a smart television further includes:
a second end determining module 500, configured to determine that playing of the currently played video is ended when a request packet containing the media uniform resource identifier is not acquired from the link layer within a preset time.
Specifically, the media stream segment currently downloaded from the server end is consumed, but the request for obtaining the next media stream segment is not continuously received at the link layer, which indicates that the currently playing video playing is also ended. There are two cases where the link layer does not continue to receive a request to retrieve the next media stream segment: first, if all media stream segments have been completely downloaded, it means playing to the end; second, if all media stream segments are not completely downloaded, it may mean that the user actively quits playing.
Further, referring to fig. 8, which is a fifth embodiment of the system for acquiring network video playing information of a smart television according to the present invention, based on any one of the first to fourth embodiments of the system for acquiring network video playing information of a smart television according to the present invention, the first playing information acquiring module 200 includes:
a determining unit 201, configured to determine whether a destination address of the request packet is a preset address when the data packet is a request packet and data in the request packet includes a video address;
a first playing information obtaining unit 202, configured to obtain and store first playing information of a currently playing video according to the data packet when the destination address of the data packet is a preset address.
In particular, since the number of packets passing through a particular portal can be enormous, it is important to set appropriate packet filtering conditions, which would place a significant performance burden on the television system if all packets were detected and could lead to inaccuracies in the detection results.
For the data packet sent from the local address, filtering may be performed according to the destination address and the destination port, for example, the destination port number may be limited to only 80, and so on. According to the filtering condition of the destination address, statistics can be carried out on information of a specific video resource acquisition path, such as the jamming condition of a server provided by Yokoku.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
