Description
Technical Field
The application relates to the technical field of internet, in particular to a method and a device for monitoring interactive video quality.
Background
Interactive television, also called interactive television, is a new generation television based on digital television and broadband network technology, and viewers respond to information through an information window on a television screen and establish two-way connection with the information on the television. The interactive Video service generated by this method is applied to a plurality of interactive Video systems such as high-definition interactive Television, Internet Television (OTT), and Internet Protocol Television (IPTV) under a Next Generation On Demand Video service (NGOD) service system. During the process of using interactive television by viewers through different interactive video systems, various links of the service may fail. In order to improve the interactive video use experience of audiences, a video content service platform or an operator needs to monitor interactive video services in real time, and operation and maintenance personnel can timely handle faults by positioning and displaying the faults.
Typical interactive video service monitoring methods include a monitoring method using a special video index measuring device and a semi-automatic inspection technology based on infrared control. When monitoring, the special video index measuring equipment can extract key parameters representing the interactive process from the service interactive signaling, but cannot extract related parameters representing the video quality, and the monitoring fault range is small. Meanwhile, the equipment does not have a video output function and cannot intuitively reflect the real viewing quality of audiences. Another monitoring method for interactive video services is a semi-automatic polling technique based on infrared control. Although the video picture quality can be visually seen at the output end, the real-time working state, the signaling interaction condition and the asset scheduling condition among the interaction servers cannot be reflected. When the video image quality is in a problem, the fault can not be positioned automatically and accurately, and the fault troubleshooting efficiency is low in the manual intervention process of operation and maintenance personnel on the fault.
With the continuous change of the interactive video system, the content service platform or the operator has changed the method, the device and the system for monitoring the interactive video service of various interactive video systems. Because both typical interactive video service monitoring methods can only be applied to a specific interactive video system, when a content service platform or an operator simultaneously monitors interactive services of multiple interactive video systems, different monitoring devices need to be used for different interactive video systems, and different monitoring methods are adopted, so that difficulty in troubleshooting is increased. In addition, the monitoring results obtained by the existing interactive video service monitoring method need to be displayed by third-party software. Therefore, the problem that a monitoring method for a plurality of interactive video systems is complex and diverse needs to be solved, so as to improve the working efficiency of operation and maintenance personnel.

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a schematic flow chart of an embodiment of an interactive video quality monitoring method provided by the present application is shown, which may specifically include the following steps:
In this embodiment, the interactive video signal received by the controller is a radio frequency signal or an IP signal. In the prior art, the interactive video quality monitoring method can only be applied to service monitoring in one scene, that is, only one type of interactive video signal can be monitored. Because the type of the signal received by the interactive video system under the NGOD service system is a Radio Frequency signal, and the type of the signal received by the OTT or IPTV-like interactive video system is an IP signal, in the prior art, operation and maintenance personnel of a content service platform and an operator cannot monitor a plurality of mainstream interactive video systems, but the present application is innovative at this point, and receives interactive video signals of two signal types, namely a Radio Frequency (RF) signal and an RJ45 network interface, and in practical application, the monitoring of the interactive video system under the NGOD service system and the OTT or IPTV-like interactive video systems can be simultaneously supported.
And 2, extracting interactive video quality information by using an interactive mode corresponding to the interactive video signal type through the controller.
In this embodiment, the controller extracts the interactive video quality information in steps by using an interactive mode corresponding to the radio frequency signal or the IP signal. When the received interactive video signal is a radio frequency signal, extracting interactive video quality information by using a Quadrature Amplitude Modulation (QAM) mode; when the received interactive video signal is an IP signal, interactive video quality information is extracted using an Internet Protocol (IP) mode. Through two working modes, the dial testing can be carried out on the interactive video system under the NGOD service system, and the dial testing can also be carried out on the OTT and IPTV-like interactive video systems.
The interactive mode corresponding to the interactive video signal type refers to an interactive mode corresponding to the signal type of the interactive video signal.
And 3, outputting the interactive video quality information by the controller.
In this embodiment, after receiving the interactive video signal and extracting the interactive video quality information, the interactive video quality information is output together with the video picture in an On Screen Display (OSD) manner, so as to achieve the purpose of monitoring the interactive video quality. Video overlay, i.e. overlaying picture and text information into video signals, such as LOGO of television station, subtitle of movie, menu of television, all displayed in video image by video overlay form. The character superimposer is currently used in various monitoring systems, and is an electronic device with relatively low price and basic video subtitle superimposing capability. According to the function type, the character superimposer can be divided into a dynamic character superimposer and a static character superimposer, the dynamic character superimposer is adopted in the embodiment, the character information which changes along with the change of the interactive video quality information can be displayed, and the accurate and detailed monitoring information is provided for a video content service platform and an operator through the combination of the character information and the video signal.
Referring to fig. 2, a schematic flow chart of extracting interactive video quality information in an embodiment of the present application is shown.
In this embodiment, the extracting, by the controller, the interactive video quality information using an interactive mode corresponding to the type of the interactive video signal includes:
in this embodiment, the interactive information corresponding to the radio frequency signal includes: program name, channel ID, channel name, interaction status. The interactive process of the controller and the server for resource request, resource positioning and code stream pushing specifically comprises the following steps: before extracting the interactive information corresponding to the radio frequency signal, the controller acquires a list of the full number of channel names and channel IDs from a Portal server. For example, the monitored interactive video system has 100 channels, i.e., a full list of 100 channel names and channel IDs is obtained. When a certain channel needs to be dialed and tested, the controller extracts the corresponding channel name and channel ID according to the list of the channel name and the channel ID. The controller carries a channel ID to be dialed and measured to request program information of a certain channel from the Portal server, extracts a program name to be dialed and an asset ID corresponding to the program name according to a review program list after the Portal server responds to the review program list of the certain channel within a period of time, performs resource positioning with the SM server according to the asset ID, then requests a code stream to be pushed from the VSS server, and finally receives the code stream pushing of the VSS server.
in this embodiment, the radio frequency information includes: frequency point, lock state, level value. The controller interacts with the SM server through the SETUP protocol to extract radio frequency information, when all interactions are normal, a protocol header returned by the SM server has 200OK words, and information required to be acquired for the interaction is in a protocol body. Similarly, when the interaction fails, the protocol header returned by the SM server has error codes similar to 404 and the like, and the error description is in the protocol body, and the error codes and the error description are extracted to alarm.
And 203, after the radio frequency information is extracted, extracting code stream information corresponding to the radio frequency signal according to an interactive signaling obtained in an interactive process of resource positioning between the controller and the SM server and a code stream obtained by code stream pushing between the controller and the VSS server.
In this embodiment, the code stream information corresponding to the radio frequency signal includes: program number, bandwidth, code stream status.
Referring to fig. 3, a schematic diagram of an interaction process between a controller and a server according to an embodiment of the present application is shown.
The method specifically comprises the following steps:
step 301, a list of full channel names and channel IDs is obtained.
Step 302, according to the list, extracting the channel name and channel ID to be dialed.
Step 303, requesting to review the program list from the Portal server according to the channel ID.
Step 304, receiving the review program list fed back by the Portal server.
And 305, extracting the program name and the asset ID to be dialed and measured according to the review program list.
And step 306, carrying out resource positioning with the SM server according to the asset ID.
Step 307, receiving the resource information fed back by the SM server.
Step 308, requesting code stream pushing from the VSS server.
Step 309, receiving the VSS server code stream push.
And extracting the interactive information corresponding to the radio frequency signal according to the interactive signaling in the interactive process. In this embodiment, the controller interacts with each server through different protocols, and extracts the interaction information corresponding to the radio frequency signal according to a protocol header of the interaction information returned by the server. For example, the controller interacts with a Portal server through a hypertext Transfer Protocol (HTTP), and interacts with an SM server through a Real Time Streaming Protocol (RTSP). Taking the example that the controller and the Portal server interact with each other through an HTTP protocol, wherein the HTTP is an abbreviation of a hypertext transfer protocol, a request/response model is adopted, a client sends a request to the server, and a request header comprises a request method, a URL (uniform resource locator), a protocol version and a message structure comprising a request modifier, client information and content. The server responds with a status line and the corresponding content includes the version of the message protocol, success or error coding, including server information, entity meta information and possibly entity content. When all the interactions are normal, the protocol header returned by the server has 200OK words, and the information required to be acquired for the interaction is in the protocol body. Similarly, when the interaction fails, the common protocol header of the server returning the interaction information has error codes similar to 404 and the like, which indicate that the requested object does not exist on the server, and the protocol body extracts the error codes and the error descriptions for the specific error description of the interaction at this time to alarm.
Referring to fig. 4, a schematic flow chart of another embodiment of the present application for extracting interactive video quality information is shown.
The controller extracts interactive video quality information using an interactive mode corresponding to the type of the interactive video signal, including:
in this embodiment, the interactive information corresponding to the network information includes: program name, channel ID, channel name, interaction status. The method for the controller and the server to perform resource request and TS slice downloading specifically comprises the following steps: before extracting the interactive information corresponding to the IP signal, the controller acquires a list of the full number of channel names and channel IDs from the Portal server. For example, an interactive video system has 100 channels, i.e., a list of 100 channel names and channel IDs is obtained. When any channel needs to be dialed and tested, the controller extracts the corresponding channel name and channel ID according to the list, requests program information of any channel to the Portal server by carrying the channel ID needing to be dialed and tested, extracts the playUrl of the corresponding program according to the review program after the Portal server responds to the review program list of any channel within a period of time, carries the playUrl to request the TS slice download to the CDN server, and finally receives the TS slice push of the CDN server.
In this embodiment, the code stream information corresponding to the IP signal includes: program number, bandwidth, code stream status.
Referring to fig. 5, a schematic diagram of another interaction process between a controller and a server according to an embodiment of the present application is shown.
The method specifically comprises the following steps:
step 501, a list of full channel names and channel IDs is obtained.
Step 502, extracting the channel name and channel ID to be dialed according to the list.
Step 503, request to the Portal server to review the program list according to the channel ID.
Step 504, receiving the review program list fed back by the Portal server.
And 505, extracting the playUrl of the program to be dialed and tested according to the review program list.
And step 506, carrying the playUrl to request a CDN server for TS slice downloading.
And step 507, receiving the TS slice pushing of the CDN server.
And extracting the interactive information corresponding to the IP signal according to the interactive signaling in the interactive process. In this embodiment, the controller interacts with each server through different protocols, and extracts the interaction information corresponding to the IP signal according to a protocol header of the interaction information returned by the server. For example, the controller interacts with the Portal server via the HTTP protocol. When all the interactions are normal, the protocol header returned by the server has 200OK words, and the information required to be acquired for the interaction is in the protocol body. Similarly, when the interaction fails, the protocol header of the interaction information returned by the server has error codes similar to 404 and the like, and the protocol body extracts the error codes and the error descriptions for the specific error description of the interaction at this time to alarm.
Referring to fig. 6, a schematic flow chart of video output in an embodiment of the interactive video quality monitoring method provided by the present application is shown, which may specifically include the following steps:
High-bandwidth Digital Content Protection (HDCP) is a decoding technique provided for High-Definition Multimedia Interface (HDMI) to prevent audio/video Content with copyright from unauthorized copying. The HDMI equipped with the HDCP decoding technology is not limited by signal encryption, and can receive high-definition signals of all formats. When the user illegally copies, the technology interferes, the quality of copied images is greatly reduced, and therefore the content is protected.
And step 103, if the device supports the HDCP, the HDMI device is opened.
And step 104, if the device does not support the HDCP, registering the callback.
And step 108, if a hot plug event exists, acquiring a device capability set.
And step 111, starting playing.
In step 112, it is determined whether a hot-plug event is present.
And step 113, stopping playing if a hot-plug event exists.
And step 115, if other operations exist, the HDMI equipment is closed.
In step 117, HDMI is de-initialized.
Referring to fig. 7, a diagram illustrating an effect in an embodiment of the interactive video quality monitoring method provided by the present application is shown.
In the prior art, due to the fact that a plurality of fault reasons that a video output picture is a black screen appear, a user often cannot directly find out a specific fault reason, the working efficiency of solving the fault is low, and the use experience is poor. According to the interactive video quality monitoring method, when the charm music channel is dialed and tested to have a fault, although the video output picture is displayed as a black screen, interactive video quality information is divided into three monitoring items and is displayed above the picture in an OSD overlapping mode, and the fault reason of the video service can be accurately positioned from the center. In the interactive information, the program information is null, the channel ID is 1002474731, the channel name is charm music, and the interactive status display error code ErrCode is 10300 and the request for acquiring the program list fails; in the radio frequency information, the frequency point is 0MHz, the locking state is displayed as out-of-lock, and the level value is displayed as 67 dB; in the code stream information, the program number is displayed as-1, the bandwidth is displayed as 0.0Mbps, and the code stream state is displayed as code stream interruption. In this embodiment, since a service failure occurs in which the acquisition of the program list fails, when a request to acquire the program list from the server is made, the server returns that the program list is empty, and the program list of the charm music channel cannot be acquired. The interactive video quality information is displayed on an output picture in an OSD overlapping mode, and the interactive video fault caused by the failure of the program list request in the interactive process can be positioned, so that the video output picture is a black screen. Therefore, after the interactive video quality monitoring method provided by the application is used for outputting the pictures through the video, the fault of the service flow level can be shown, the quality fault of the video can be defined, and the inconvenience that the fault can only be displayed through the cooperation of third-party software in the conventional interactive video quality monitoring method is avoided.
In this embodiment, the video output picture can simultaneously support multiple video output modes such as HDMI, portal, WIFI, and the like, and the portal or WIFI output mode supports UDP unicast/multicast and HTTP streaming media services. The implementation principle is that the demodulated radio frequency signal or the original TS stream directly downloaded is decoded and then secondarily encoded, and then output in a mode of HDMI or UDP/HTTP streaming media service.
On the basis of the above embodiments, the present embodiment further provides an interactive video quality monitoring apparatus.
