## Background
RELATED APPLICATION
This application is a continuation application of PCT Patent Application No. PCT/CN2015/081331, entitled “METHOD AND SYSTEM FOR TESTING AND MONITORING A REAL-TIME STREAMING MEDIA RECOGNITION SERVICE PROVIDER” filed on Jun. 12, 2015, which claims priority to Chinese Patent Application No. 201410327529.4, entitled “METHOD AND SYSTEM FOR TESTING AND MONITORING A REAL-TIME STREAMING MEDIA RECOGNITION SERVICE PROVIDER” filed on Jul. 10, 2014, both of which are incorporated by reference in their entirety.


TECHNICAL FIELD
The present application relates to multimedia technologies, and in particular, to method and system for testing and monitoring a real-time streaming media recognition service provider.
BACKGROUND
Streaming media are audio, image, video, text and multimedia files transmitted in a network in a manner of streaming. The network refers to a wired broadcasting network, a wireless broadcasting network, the Internet and the like. A streaming media file format is a media format that supports streaming transmission and playing.
Real-time streaming media usually use streaming transmission. The streaming transmission is to compress multimedia files such as video and into separate compressed packages that are continuously transmitted to a computer by a server in real time. In a system using streaming transmission, to view content of a file, a user does not need to wait until the file is completely downloaded as the user does during non-streaming playing. Instead, after a few seconds or dozens of seconds of startup delay, the user can play the streaming media file such as compressed video or audio on a computer with a corresponding player, and the rest part will be continuously downloaded until the playing is completed.
A conventional system for testing and monitoring streaming media use fixed testing samples and output results that can be used repeatedly. However, in a real-time streaming media recognition service provider, because the streaming media changes in real time, whether a testing sample is effective depends on time. A corresponding result can be recognized in an effective time window, while the testing sample becomes ineffective out of the time window. The real-time streaming media recognition service provider cannot return an expected recognizing result, and therefore, whether functions and stability of the real-time streaming media recognition service provider are normal cannot be determined.
SUMMARY
The above deficiencies and other problems associated with the conventional approach of testing and monitoring the function and performance of a real-time streaming media recognition service provider are reduced or eliminated by the invention disclosed below. In some embodiments, the present application is implemented in a computer system (e.g., computer server, etc.) that has one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions.

One aspect of the present application involves a computer-implemented method of testing and monitoring a real-time streaming media recognition service provider performed at a computer system. The computer system obtains a streaming media signal source, selects a testing sample from the streaming media signal source, records characteristics of the testing sample, and obtains an expected output according to the characteristics of the testing sample. Next, the computer system converts the testing sample into a digital streaming format preset by the service provider and initiates a media recognition request according to the testing sample in the digital streaming format to the service provider. After receiving a media recognition result of the testing sample returned by the service provider according to the media recognition request, the computer system compares the media recognition result with the expected output and indicates whether the service provider is normal in accordance with the comparison result.

DESCRIPTION OF EMBODIMENTS
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject matter presented herein. But it will be apparent to one skilled in the art that the subject matter may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
In order to make the objectives, technical solutions, and advantages of the present application easier to understand, the present application is described in further detail in the following with reference to the accompanying drawings and the embodiments. It should be understood that, the specific embodiments described here are only used to explain the present application, but are not used to limit the present application.
Today, more and more people use different client-side electronic devices (e.g., desktop, laptop, tablet and smartphones) to receive real-time information (e.g., news, a sports game) from online service providers through streaming media services offered by the online service providers. Because of the diverse nature of these client-side devices and the real-time fashion of the Internet environment, the online service providers need to monitor the quality of such streaming media services in real time, identify issues experienced by any client-side devices and fix the issues as quickly as possible. The present application is directed to a method of testing and monitoring the function and performance of a real-time streaming media recognition service provider and a system implementing the method. Using such method and system, the operator of the real-time streaming media recognition service provider can identify and solve an issue experienced by its customers before the issue escalates into a significant problem or even a disaster in terms of user experience.
FIG. 1 is a flowchart of a method for testing and monitoring a real-time streaming media recognition service provider in an embodiment. As shown in FIG. 1, the method for testing a real-time streaming media recognition service provider includes the following steps:
Step 102: Obtain a streaming media signal source, select a testing sample from the streaming media signal source, and record characteristics of the testing sample.
Specifically, a real-time streaming media signal source is obtained, where the streaming media signal source may be a signal source captured from a television or radio or by other capturing devices.
After the obtaining a streaming media signal source, the method further includes: converting the testing sample into a digital streaming format preset by a real-time streaming media service. In some embodiments, each digital streaming format is supported by a predefined set of client-side devices. The system rotates among a set of digital streaming formats to perform the testing and monitoring operations to make sure that the real-time streaming media service provider support as many client-side devices of different types as possible. In some embodiments, the system randomly selects one digital streaming format to perform the testing and monitoring operations. In other embodiments, the system follows a predefined order to perform the testing and monitoring operations for different digital streaming formats.
The streaming media signal source may be a signal source such as television audio, an image screenshot or radio audio. The streaming media signal source is converted into a digital streaming format preset by the real-time streaming media service. The converted signal source may be audio of a certain length, one or more image screenshots, or an extracted feature value of audio or an image. Then, a streaming media segment is selected from the converted streaming media signal source, and is used as a testing sample for testing and monitoring, and identification information such as an attribute and an identifier of the testing sample is recorded.
The testing sample refers to streaming media data input to a real-time streaming media recognition service provider. The real-time streaming media recognition service provider is a background service system which processes streaming media in a backend server, recognizes certain information from streaming media information, and provides more specific recognizing information. For specific content types of different streaming media, the system can recognize different streaming media such as audio, video, multimedia, and text. Testing refers to a system environment for verifying actual functions and performance of the real-time streaming media recognition service provider before releasing its service. Monitoring refers to a system environment for monitoring and tracking stability of the real-time streaming media recognition service provider and issuing fault alarms after releasing its service.
The recorded characteristics of the testing sample include the attributes and identifier of the testing sample. Attributes of different testing samples are different. For example, if a testing sample is television audio, the attributes include time when the television audio is extracted, length and size of the television audio, television channel information of the extracted television audio, a source of the extracted television audio and the like. The identifier is used for uniquely identifying a testing sample, such as television channel information.
In the method for testing and monitoring for a real-time streaming media recognition service provider, the step of selecting a testing sample from the streaming media signal source includes: selecting the testing sample from the streaming media signal source at a preset time interval. Specifically, the preset time interval may be set as required, for example, 10 seconds or 15 seconds.
Step 104: Initiate a media recognition request according to the testing sample to a real-time streaming media recognition service provider, and receive a media recognition result of the testing sample returned according to the media recognition request.
In this embodiment, the step of initiating a media recognition request according to the testing sample includes: initiating the media recognition request according to the testing sample by complying with a client request protocol of the real-time streaming media recognition service provider.
A program is used to a simulate a client of the real-time streaming media recognition service provider, so as to originate the media recognition request for a backend real-time streaming media recognition service provider and receive the returned media recognition result, which avoids dependence on hardware equipment, in addition, a protocol format and command used by the media recognition request are consistent with those of the client, so as to ensure that the real-time streaming media recognition service provider can receive and process them correctly. Content included in the media recognition result differs for different testing samples. For example, if the testing sample is television audio, the media recognition result may include a value of television channel information and the like; if the testing sample is radio audio, the media recognition result may include a value of radio channel information, for example, the number corresponding to an 88.8 Hz radio channel is 0001.
Step 106: Obtain an expected output according to characteristics of the testing sample, and compare the media recognition result with the expected output; if the two are same, indicate that the real-time streaming media recognition service provider is normal; otherwise, indicate that the real-time streaming media recognition service provider is abnormal.
In this embodiment, the recorded characteristics of the testing sample include the attribute and identifier of the testing sample. The attribute and identifier of the media recognition result are compared with the recorded attribute and identifier of the testing sample. If they are same, it indicates that the real-time streaming media recognition service provider is normal; otherwise, it indicates that the real-time streaming media recognition service provider is abnormal. Herein, the service being normal means that functions and stability of the real-time streaming media recognition service provider are normal, and the service being abnormal means that functions and stability of the real-time streaming media recognition service provider are in an abnormal state.
The expected output refers to a preset result that is expected to be obtained according to the testing sample after testing. For example, if the testing sample is television audio, attribute content of the television audio includes time when the television audio is extracted (for example, extraction starts at 15:30:20, Jun. 24, 2014), length of television audio (10 seconds), size (20 kilobytes), television channel information of the extracted television audio, and a source of the extracted television audio. The television channel information is used as an identifier of the television audio, and the identifier is used as a value for determining the expected output of the television audio. For example, if the testing sample is radio audio, attribute content of the radio audio includes time when the radio audio is extracted (for example, extraction starts at 15:30:20, Jun. 24, 2014), length of radio audio (10 seconds), size (20 kilobytes), radio channel information of the extracted radio audio, and a source of the extracted radio audio. The radio channel information is used as an identifier of the radio audio, and the identifier is used as a value for determining the expected output of the radio audio. The returned media recognition result is a value of television audio information, and the returned value of the television audio information is compared with an expected value of the television audio information. If the two are same, it indicates that the real-time streaming media recognition service provider is normal; otherwise, it indicates that the real-time streaming media recognition service provider is abnormal.
Specifically, for example, the testing sample is television audio. If the television channel to be tested is CCTV-1 and a corresponding ID number of CCTV-1 in the real-time streaming media recognition service is 001, the system 200 for testing and monitoring a real-time streaming media recognition service provider is connected to a CCTV-1 channel television signal source (a cable television signal or a satellite television signal), uses a real-time streaming media recognition service to extract a feature of the television signal source, and captures clips (for example, 3 seconds, 5 seconds or 8 seconds) of the extracted feature of the television signal source by a length of the feature audio clips (which may be a preset length) captured by the client of the real-time streaming media recognition service. A simulated client of the real-time streaming media recognition service sends the extracted feature of the fixed length to the real-time streaming media recognition service according to a preset protocol, and receives the result returned by the real-time streaming media recognition service provider. Because it is known that the signal source for the testing sample is the CCTV-1 channel, the expected output of the testing is the ID number 001 of the CCTV-1 channel. When the received ID number in the media recognition result returned by the real-time streaming media recognition service provider is 001, the media recognition result is consistent with the expected output, which indicates that the real-time streaming media recognition service provider correctly recognizes the testing sample. If the ID number in the media recognition result is not 001, the media recognition result is inconsistent with the expected output, which indicates that the real-time streaming media recognition service provider fails to recognize the testing sample correctly. Similarly, by using different television signal sources, extracting features, and using the features as testing samples, whether the real-time streaming media recognition service provider can accurately recognize a program of each television channel can be verified one by one, so as to meet recognizing and monitoring requirements.
In the method for testing and monitoring a real-time streaming media recognition service provider, a testing sample is selected from a streaming media signal source, the testing sample is analyzed to obtain a media recognition result, and the media recognition result is compared with an expected output of the testing sample, and if the two are same, it indicates that the real-time streaming media recognition service provider is normal. A segment of streaming media is extracted from the real-time streaming media signal source to generate the testing sample, the expected output of the testing sample is recorded, and the media recognition result is compared with the expected output, which achieves real-time testing and monitoring of the real-time streaming media recognition service provider and ensures that functions and stability of the real-time streaming media recognition service provider are in a normal state.

The identifier is used for uniquely identifying a testing sample, such as television channel information.
The real-time streaming media obtaining and processing module 220 is further configured to select the testing sample from the streaming media signal source at a preset time interval. Specifically, the preset time interval may be set as required, for example, 10 seconds or 15 seconds.
