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.
Referring to fig. 1, a flowchart of a method for monitoring playback of an audio/video file according to an embodiment of the present invention is shown. In the embodiment of the invention, the method for monitoring the playing of the audio and video file comprises the following steps:
step S10, the data processing equipment implants identification information on the video file; in the embodiment of the present invention, the data processing device may be a computer, and the audio/video file may be a movie or an advertisement inserted in the movie, such as a film or a digital adaptive master disc. The identification information can be implanted into the beginning and the end of the video file, so that the playing time length of the whole file can be known. It can also be selectively implanted, such as at midfield rest or only at the beginning of the slice.
Step S20, the monitoring device captures the identification information on the screen in the playing process of the video file, decodes the identification information into digital information and uploads the digital information to the background server; this step may include: capturing identification information on a screen; decoding the identification information and converting the identification information into digital information; and uploading the digital information to a background server through GPRS, WIFI, Bluetooth, frequency modulation FM, 2.4GHz or USB. In the embodiment of the invention, the monitoring equipment can be installed in a cinema, a DSP (Digital Signal Processing) chip and a CCD (Charge-coupled Device) lens are arranged in the cinema, the identification information captured by the central position of a screen can be decoded in real time, and the content meeting the requirements can be decoded into a single character string and uploaded to a background server. The monitoring device can upload the digital information to the background server in a wireless or wired manner, for example, the digital information can be uploaded to the background server through GPRS, WIFI, Bluetooth, frequency modulation FM, 2.4GHz or USB.
And step S30, the background server analyzes the received digital information and generates a monitoring report. After the monitoring equipment captures the identification information of the video and audio file, the time and place of the video can be known, and the playing time can be known. After the background server receives the digital information, a broadcast monitoring report can be generated according to the information such as the playing time, the playing place, the playing duration and the like. The user can inquire the playing information of the video file by logging in the background server.
The identification information is implanted into the video file (such as a movie or movie advertisement), then in the movie playing process, the specific information or code on the screen is captured by the terminal equipment for decoding and identification and is stored as digital information, and the identification result is transmitted to the background data server in real time. From the capture, identification, decoding, storage to sending of identification information, the whole process can be completed within a few seconds, and is very quick and efficient.
Referring to fig. 2, in the embodiment of the present invention, the step S10 specifically includes:

In the embodiment of the present invention, the identification information may be specific codes or graphic information, such as one-dimensional codes, two-dimensional codes, digital codes, symbol codes, characters or graphics. The identification information part generally accounts for one tenth of the whole screen, and the duration is about 1 second (more than 20 frames is optimal).
And step S12, storing the identification information and the ID number ID of the monitoring equipment into a database of the background server. For example, the computer may store the identification information of a certain movie or movie advertisement and the ID of the monitoring device into the backend server for the backend server to analyze and sort, thereby generating a corresponding watch list.
In an embodiment of the present invention, the step S30 may include:
generating a monitoring report according to the playing time, the playing place, the audio and video file name and the playing time; and/or
