Description

Technical Field

[0001] This invention relates to the field of streaming media playback technology, and in particular to an IPTV testing method, system, device, and computer-readable storage medium. Background Technology

[0002] In the current technology, with the development of the Internet, IPTV services provided by the three major telecom operators have become a basic user requirement. Because the IPTV services offered by different operators vary, the optical modems and set-top boxes provided to users also differ in their customization. Therefore, it is necessary to improve the testing and acceptance standards for IPTV service scenarios using edge routers.

[0003] The current testing scenario involves directly connecting the edge router to the optical modem, and the set-top box to the edge router, specifically as follows: Figure 14 As shown, this test scenario can no longer meet the comprehensive testing environment requirements for IPTV service playback, specifically in the following aspects:

[0004] First, the performance of IPTV video playback at different resolutions cannot be effectively tested; second, the playback performance under different IPTV stream parameters cannot be effectively tested; the compatibility of IGMP (Internet Group Management Protocol) versions cannot be tested; and due to network fluctuations, the root cause of problems such as video playback stuttering cannot be quickly located and analyzed.

[0005] Therefore, how to improve the effectiveness, comprehensiveness, and convenience of IPTV testing has become an urgent technical problem to be solved. Summary of the Invention

[0006] To address the shortcomings of existing technologies, such as the inability to effectively test the performance of IPTV video playback at different resolutions and with different IPTV stream parameters, the inability to test IGMP protocol version compatibility, and the inability to quickly locate and analyze the root causes of video playback stuttering due to network fluctuations, this invention proposes an IPTV testing method, system, device, and computer-readable storage medium.

[0007] Specifically, an IPTV testing method, applied to a simulated server, includes:

[0008] Based on the current testing requirements, select a video source file as the test source in the preset streaming media software, and configure the protocol type, current multicast address, and current version of the Internet Group Management Protocol for the test source stream.

[0009] Access the edge router to be tested, so that the simulated client accessing the edge router joins the multicast group corresponding to the multicast address according to the current version of the Internet Group Management Protocol;

[0010] During the joint simulation test conducted by the simulated server, the edge router, and the simulated client, one or more of the following are adjusted: video parameters of the test source, protocol type of the streaming stream, and version of Internet Group Management Protocol. The first packet interaction between the simulated server and the edge router is then tested and analyzed based on the first packet capture data.

[0011] Optionally, the video parameters include one or more of video resolution, video bitrate, video size, and video duration, and adjusting one or more of the video parameters of the test source, the protocol type of the stream, and the version of the Internet Group Management Protocol specifically includes:

[0012] The video parameters are modified by selecting a video source file with one or more of the following characteristics from local storage: video resolution, video bitrate, video size, and video duration.

[0013] Optionally, the version of the Internet Group Management Protocol (IGMP) includes a first version, a second version, and a third version, and adjusting one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IGMP specifically includes:

[0014] The version of the Internet Group Management Protocol (IGMP) can be modified by adjusting the numbers in the IGMPVersion and IGMPLevel fields in the current version script of the IGMP.

[0015] Optionally, the step of testing and analyzing the first packet interaction between the simulated server and the edge router based on the first packet capture data further includes:

[0016] Obtain the playback status of the simulated client;

[0017] When the playback state meets the preset first condition, one or more of the following are adjusted according to the playback state: video parameters of the test source, protocol type of the stream, and version of Internet Group Management Protocol.

[0018] When the playback status meets the preset second condition, the first message interaction is tested and analyzed based on the first data.

[0019] This invention also proposes an IPTV testing method applied to a simulated client, the method comprising:

[0020] Start network streaming and enter the current multicast address;

[0021] Connect to the edge router to be tested and join the multicast group corresponding to the current multicast address according to the current version of the Internet Group Management Protocol;

[0022] Start playing multicast video, and test and analyze the second message interaction between the simulated client and the edge router based on the second data captured by the packet capture. During the simulation test jointly conducted by the simulated server, the edge router and the simulated client, the simulated server modifies one or more of the following: the video parameters of the test source, the protocol type of the stream and the version of the Internet Group Management Protocol.

[0023] Optionally, the step of starting to play multicast video and testing and analyzing the second packet interaction between the simulated client and the edge router based on the second data captured by packet sniffing specifically includes:

[0024] When the playback smoothness of the multicast video meets the preset playback conditions, the multicast video is determined to have played successfully.

[0025] When the playback smoothness does not meet the playback conditions, it is determined that the multicast video playback has failed, and the second packet capture is started. The second packet interaction between the simulated client and the edge router is tested and analyzed based on the second data obtained from the packet capture.

[0026] Optionally, starting to play the multicast video and testing and analyzing the second packet interaction between the simulated client and the edge router based on the second data captured by packet sniffing further includes:

[0027] When it is determined that the multicast video playback has failed, a message containing the current playback status is sent to the simulation server, so that the simulation server can adjust one or more of the video parameters of the test source, the protocol type of the stream, and the version of the Internet Group Management Protocol according to the playback status, and / or start capturing the first packet, and perform test analysis on the first packet interaction based on the first data obtained from the packet capture.

[0028] This invention also proposes an IPTV testing system, which includes: an edge router, a simulated server connected to the edge router, and a simulated client, wherein...

[0029] The simulation server is used to: select a video source file as the test source from a preset streaming media software according to the current test requirements; configure the protocol type, current multicast address, and current version of the Internet Group Management Protocol (IGMP) of the test source stream; connect to the edge router to be tested, so that the simulation client connected to the edge router joins the multicast group corresponding to the multicast address according to the current version of the IMP; during the joint simulation test by the simulation server, the edge router, and the simulation client, adjust one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IMP, and perform test analysis on the first packet interaction between the simulation server and the edge router based on the first packet capture data;

[0030] The simulated client is used to: start a network stream and input the current multicast address; connect to the edge router to be tested and join the multicast group corresponding to the current multicast address according to the current version of the Internet Group Management Protocol; start playing the multicast video; and perform test analysis on the second message interaction between the simulated client and the edge router based on the second packet capture data. During the joint simulation test by the simulated server, the edge router, and the simulated client, the simulated server modifies one or more of the following: the video parameters of the test source, the protocol type of the stream, and the version of the Internet Group Management Protocol.

[0031] The present invention also proposes an IPTV testing device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the IPTV testing method as described in any of the preceding claims.

[0032] The present invention also proposes a computer-readable storage medium storing an IPTV test program, which, when executed by a processor, implements the steps of the IPTV test method as described in any of the preceding claims.

[0033] The present invention provides an IPTV testing method, system, device, and computer-readable storage medium. It involves selecting a video source file as the test source from preset streaming media software based on current testing requirements, and configuring the protocol type, current multicast address, and current version of the Internet Group Management Protocol (IGMP) for the test source stream. The system then connects to an edge router to be tested, enabling a simulated client connected to the edge router to join a multicast group corresponding to the multicast address based on the current version of the IMP. During the simulated test conducted jointly by the simulated server, the edge router, and the simulated client, one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IMP are adjusted. Finally, the system tests and analyzes the first packet interaction between the simulated server and the edge router based on the first packet capture data. This invention provides a more convenient, efficient, and comprehensive IPTV testing solution. It eliminates the need to rely on operators to provide IPTV services. The testing environment and system are built according to testing requirements. Video resources of different resolutions or bitrates are built according to testing needs, and video multicast streams with different output protocols are built according to testing needs. The IGMP protocol version is adjusted by modifying the registry to test IGMP protocol compatibility. The IPTV service network environment built is simple, and it is easy to locate, analyze, and troubleshoot problems such as video playback stuttering. Attached Figure Description

[0049] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0050] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0051] Figure 1 This is the first flowchart of the IPTV testing method of the present invention. This embodiment proposes an IPTV testing method applied to a simulated server, the method comprising:

[0052] S1. Based on the current testing requirements, select a video source file as the test source in the preset streaming media software, and configure the protocol type, current multicast address, and current version of the Internet Group Management Protocol for the test source stream.

[0053] S2. Connect to the edge router to be tested, so that the simulated client connected to the edge router joins the multicast group corresponding to the multicast address according to the current version of the Internet Group Management Protocol;

[0054] S3. During the joint simulation test conducted by the simulated server, the edge router, and the simulated client, one or more of the following are adjusted: video parameters of the test source, protocol type of the stream, and version of Internet Group Management Protocol. The first packet interaction between the simulated server and the edge router is tested and analyzed based on the first packet capture data.

[0055] Optionally, the video parameters include one or more of video resolution, video bitrate, video size, and video duration, and adjusting one or more of the video parameters of the test source, the protocol type of the stream, and the version of the Internet Group Management Protocol specifically includes:

[0056] The video parameters are modified by selecting video source files with one or more of the following characteristics from local storage: video resolution, video bitrate, video size, and video duration. Specifically, the selection of video source files with one or more of these characteristics is based on the current testing requirements and scenario. For example, the video resolution parameter is set according to the current testing requirements, and then a video file with the corresponding resolution is selected from the local video library based on this parameter. Alternatively, if the initial parameters of the local test video are inconsistent with the parameters specified in the testing requirements, the initial parameters are converted to the parameters specified in the testing requirements.

[0057] Optionally, the version of the Internet Group Management Protocol (IGMP) includes a first version, a second version, and a third version, and adjusting one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IGMP specifically includes:

[0058] The version of the Internet Group Management Protocol (IGMP) can be modified by adjusting the numbers in the IGMPVersion and IGMPLevel fields of the current version script. For example, the IGMP IGMP IGMP protocol includes three versions: V1, V2, and V3. In this embodiment, the modification of the IGMP protocol version is achieved by modifying the IGMP protocol version script, that is, configuring the server's IGMP protocol version according to the testing needs. The method for modifying the IGMP protocol version script adjustment includes editing the IGMPVersion and IGMPLevel fields in the script to the corresponding numbers. For example, when testing the IGMPv2 protocol version, the number after the IGMPVersion field is changed to 3, and the number after the IGMPLevel field is changed to 2. The IGMP version number rule is that the number 2 corresponds to IGMPv1, the number 3 corresponds to IGMPv2, and the number 4 corresponds to IGMPv3 (default); while the rule for the IGMPLevel field is that the number 0 corresponds to no multicast support, the number 1 corresponds to only supporting IPv4 multicast, and the number 2 corresponds to full IGMP support (default).

[0059] Optionally, the step of testing and analyzing the first packet interaction between the simulated server and the edge router based on the first packet capture data further includes:

[0060] Obtain the playback status of the simulated client;

[0061] When the playback state meets the preset first condition, one or more of the following are adjusted according to the playback state: video parameters of the test source, protocol type of the stream, and version of Internet Group Management Protocol.

[0062] When the playback status meets the preset second condition, the first message interaction is tested and analyzed based on the first data.

[0063] In this embodiment, the first condition refers to the fact that when the simulated client of Computer 2 plays a video, the playback parameters such as smoothness and latency meet preset test conditions. These test conditions include a test success condition, such as a smoothness threshold. If the current video playback smoothness is greater than or equal to the smoothness threshold, the playback state is determined to meet the preset first condition. Alternatively, the test conditions may include test item conditions, such as multiple latency thresholds of different levels. The latency thresholds are selected from high to low. When a higher latency threshold is met, the playback state is determined to meet the preset first condition. The test source is then adjusted or replaced to continue executing the determination of a lower latency threshold. This process is repeated, and the test analysis is performed step by step according to the progress of the playback state meeting the preset first condition. Similarly, in this embodiment, the second condition refers to the fact that when the simulated client of Computer 2 plays a video, the playback parameters such as smoothness and latency cannot meet the preset test conditions. At this time, on the one hand, it is necessary to test and analyze the first message interaction based on the first data. On the other hand, the test source can be adjusted or replaced to continue to execute the playback status determination. In this process, the first message interaction is also tested and analyzed based on the first data to select a more suitable video source for the next test.

[0064] Optionally, the streaming media software in this embodiment is VLC (a free and open-source cross-platform multimedia player and framework). The test method for building an IPTV server based on VLC software simulates the IPTV service scenario of operators, and realizes the simulation of application scenarios for testing according to the actual IPTV service scenarios of different operators, or even different provinces and cities, so as to ensure that the test results meet the acceptance requirements.

[0065] Specifically, such as Figure 2 The diagram shows the test environment. On computer one, a simulated IPTV server is built using VLC software. Simultaneously, Wireshark (a network analysis tool) is used on this computer to capture packets and analyze the message interactions between the server and the edge router, facilitating problem localization and analysis during the test. Meanwhile, on computer two, VLC software is also used to simulate a client playing IPTV video. Again, Wireshark is used on this computer to capture packets and analyze the message interactions between the client and the edge router, facilitating problem localization and analysis during the test.

[0066] In this embodiment, for the application scenario described above, a comprehensive test of the IPTV service is achieved by configuring parameters such as video source resolution, video bitrate, and IGMP protocol version on the server.

[0067] In this embodiment, special consideration is given that the operator's IPTV service mainly consists of two parts: first, joining or leaving multicast streams via the IGMP protocol; and second, different operators using different protocols to transmit video streams to the terminal. Currently, the aforementioned IGMP protocol includes three versions: V1, V2, and V3, and the video resolution played in the operator's IPTV service is generally fixed. Therefore, when testing IPTV services, it is also necessary to test the version compatibility of the IGMP protocol and the playback of videos with different resolutions and bitrates.

[0068] In this embodiment, to achieve the above testing requirements, a specific configuration of an IPTV server based on VLC software will be provided:

[0069] Please refer to Figure 3 The diagram illustrates how to add a video source. In VLC, you can add a local video file as a video source by clicking "Media -> Stream -> File -> Add".

[0070] Please refer to Figure 4 The diagram shows the streaming settings. In the VLC software, clicking "Stream" determines the source of the stream output.

[0071] Please refer to Figure 5 The diagram shows the setup for the stream target location. In the VLC software, after determining the source of the stream output, click "Next." Taking UDP (User Datagram Protocol) as an example, select "UDP" and then click "Add."

[0072] Please refer to Figure 6 The diagram shows the source address and port settings. Specifically, after selecting "UDP" and clicking "Add," the source address and port information are set on the page where you select the target location for the stream.

[0073] Please refer to Figure 7 The diagram shows the transcoding options settings. After setting the source address and port information, click "Next" and check "Activate transcoding".

[0074] Please refer to Figure 8 Another transcoding option setting diagram is shown. After checking "Activate transcoding" and clicking "Next", the current option status of "Stream all basic streams" is set by default. Click "Stream" to complete the setting.

[0075] In this embodiment, the modification of the IGMP protocol version is achieved by modifying the IGMP protocol version script, that is, configuring the server's IGMP protocol version according to the testing requirements. The method for modifying the IGMP protocol version script includes editing the IGMPVersion and IGMPLevel fields in the script to the corresponding numbers. For example, when testing the IGMPv2 protocol version, the number after the IGMPVersion field is changed to 3, and the number after the IGMPLevel field is changed to 2. The IGMP version number rule is that the number 2 corresponds to IGMPv1, the number 3 corresponds to IGMPv2, and the number 4 corresponds to IGMPv3 (default); while the rule for the IGMPLevel field is that the number 0 corresponds to no multicast support, the number 1 corresponds to only supporting IPv4 multicast, and the number 2 corresponds to full IGMP support (default).

[0076] The beneficial effects of this embodiment are as follows: A video source file is selected as the test source in a preset streaming media software according to the current testing requirements, and the protocol type, current multicast address, and current version of the Internet Group Management Protocol (IGMP) of the test source stream are configured; the edge router to be tested is connected, so that the simulated client connected to the edge router joins the multicast group corresponding to the multicast address according to the current version of the IMP; during the joint simulation test by the simulated server, the edge router, and the simulated client, one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IMP are adjusted, and the first packet interaction between the simulated server and the edge router is tested and analyzed based on the first packet capture data. This solution provides a more convenient, efficient, and comprehensive IPTV testing approach. It eliminates the need to rely on IPTV services provided by operators. The test environment can be built according to specific testing requirements, including video resources of different resolutions or bitrates. It can also output multicast streams with different protocols. The IGMP protocol version can be adjusted by modifying the registry to test IGMP compatibility. The resulting IPTV service network environment is simple, facilitating problem localization, analysis, and troubleshooting when issues such as video playback stuttering occur.

[0077] Please refer to Figure 9 The present invention also proposes an IPTV testing method applied to a simulated client, the method comprising:

[0078] S10. Start network streaming and enter the current multicast address;

[0079] S20. Connect to the edge router to be tested and join the multicast group corresponding to the current multicast address according to the current version of the Internet Group Management Protocol;

[0080] S30. Start playing the multicast video and perform test analysis on the second message interaction between the simulated client and the edge router based on the second data captured by the packet capture. During the joint simulation test by the simulated server, the edge router and the simulated client, the simulated server modifies one or more of the following: the video parameters of the test source, the protocol type of the streaming stream and the version of the Internet Group Management Protocol.

[0081] Optionally, the step of starting to play multicast video and testing and analyzing the second packet interaction between the simulated client and the edge router based on the second data captured by packet sniffing specifically includes:

[0082] When the playback smoothness of the multicast video meets the preset playback conditions, the multicast video is determined to have played successfully.

[0083] When the playback smoothness does not meet the playback conditions, it is determined that the multicast video playback has failed, and the second packet capture is started. The second packet interaction between the simulated client and the edge router is tested and analyzed based on the second data obtained from the packet capture.

[0084] Optionally, starting to play the multicast video and testing and analyzing the second packet interaction between the simulated client and the edge router based on the second data captured by packet sniffing further includes:

[0085] When it is determined that the multicast video playback has failed, a message containing the current playback status is sent to the simulation server, so that the simulation server can adjust one or more of the video parameters of the test source, the protocol type of the stream, and the version of the Internet Group Management Protocol according to the playback status, and / or start capturing the first packet, and perform test analysis on the first packet interaction based on the first data obtained from the packet capture.

[0086] Specifically, such as Figure 10 The diagram shows how to enable network streaming. Specifically, on the IPTV playback device (computer two), open the VLC software and select network streaming.

[0087] like Figure 11 The diagram shows the multicast address settings. After selecting network stream, in the network URL configuration interface, enter the URL corresponding to the server multicast address configured on the aforementioned computer after configuring the IPTV server.

[0088] like Figure 12 The diagram illustrates the playback process. Once the configuration is complete, multicast video playback can begin, and IPTV testing can commence.

[0089] In this embodiment, the test results are analyzed. Specifically: a successful test means the IPTV playback terminal (Computer 2) can play the video provided by the IPTV server normally without significant stuttering. A failed test means the IPTV playback terminal (Computer 2) cannot play the video provided by the IPTV server normally, or there is significant stuttering during playback. In this case, Wireshark is opened simultaneously on both the IPTV server (Computer 1) and the IPTV playback terminal (Computer 2) to capture packets. The problem is then reproduced, and the analysis results are used to pinpoint the source of the problem.

[0090] As can be seen, the testing scheme adopted in this embodiment only requires VLC open-source software, a Windows operating system, and two computers. The server is manually set up, and all configuration parameters can be arbitrarily configured according to the needs of the testing scenario; the testing environment is simple to set up and can be flexibly built in any environment.

[0091] The beneficial effects of this embodiment are as follows: A simulated client initiates a network stream and inputs the current multicast address; it connects to the edge router under test and joins the multicast group corresponding to the current multicast address according to the current version of the Internet Group Management Protocol (IGMP); it starts playing multicast video and tests and analyzes the second packet interaction between the simulated client and the edge router based on the captured second data. During the joint simulation test by the simulated server, the edge router, and the simulated client, the simulated server modifies one or more of the video parameters of the test source, the protocol type of the stream, and the version of the IGMP. This achieves a more convenient, efficient, and comprehensive IPTV testing solution. It does not rely on IPTV services provided by operators. The test environment is built according to testing needs, and video resources of different resolutions or bitrates are built according to testing needs. Video multicast streams with different output protocols are built according to testing needs. The IGMP protocol version is adjusted by modifying the registry to test IGMP protocol compatibility. The built IPTV service network environment is simple, and it is easy to locate, analyze, and troubleshoot problems such as video playback stuttering.

[0092] Please refer to Figure 13The block diagram shown is for reference only. This invention also proposes an IPTV testing system, which includes an edge router 10, a simulation server 20 connected to the edge router 10, and a simulation client 30. Specifically, the simulation server 20 is used to select a video source file as the test source from a preset streaming media software according to current testing requirements, and configure the protocol type, current multicast address, and current version of the Internet Group Management Protocol (IGMP) for the test source stream; connect to the edge router 10 to be tested, so that the simulation client 30 connected to the edge router 10 joins the multicast group corresponding to the multicast address according to the current version of the IMP; and adjust the video parameters of the test source, the protocol type of the stream, and the version of the IMP during the joint simulation test conducted by the simulation server 20, the edge router 10, and the simulation client 30. One or more of the following are used: the simulated server 20 and the edge router 10 are tested and analyzed based on the first packet capture data; the simulated client 30 is used to start a network stream and input the current multicast address; it connects to the edge router 10 to be tested and joins the multicast group corresponding to the current multicast address according to the current version of the Internet Group Management Protocol; it starts playing multicast video and tests and analyzes the second packet interaction between the simulated client 30 and the edge router 10 based on the second packet capture data. During the joint simulation test by the simulated server 20, the edge router 10 and the simulated client 30, the simulated server 20 modifies one or more of the following: the video parameters of the test source, the protocol type of the stream and the version of the Internet Group Management Protocol.
