With the gradual development of science and technology, display screens are ubiquitous, and a considerable part of display screen devices are widely used as advertising machines and are installed in places with large traffic of people, such as elevators, public transport vehicles, waiting rooms and the like. These display screen devices play video advertisements continuously, and the multimedia files played by these display screen devices have two sources, one is to use a storage device to locally store multimedia data through a network, and the other is to distribute the multimedia data in a streaming format through a remote server and play the multimedia data on the display screen devices. The multimedia file played locally is identified by the advertisement operator before being played, and the display screen equipment receives the multimedia file sent remotely and plays the multimedia file at the same time. Thus, it is difficult to determine the legitimacy of the file. In order to solve the problem, the related art needs to specially modify the screen, so that some screens can only be used for identifying multimedia files and are not beneficial to installation.
The method comprises the steps of obtaining a multimedia file and playing the multimedia file, obtaining an identification two-dimensional code corresponding to the multimedia file, then overlapping the identification two-dimensional code on a picture of the multimedia file to play, then judging whether the identification two-dimensional code is consistent with a standard two-dimensional code, and stopping playing the multimedia file if the identification two-dimensional code is inconsistent with the standard two-dimensional code. The method can ensure the legality of playing the multimedia file.
Referring to fig. 1, in the embodiment of the present invention, a display screen 101, a camera module 102, and a server 103 are provided. The display screen 101 is used for receiving and playing multimedia files, and has a processor built therein, and the processor is used for judging the validity of the multimedia files. The camera module 102 is connected with the display screen 101 through a bus module, and the camera module 102 is used for acquiring the identification two-dimensional code of the multimedia file. The server 103 is connected with the processor in the display screen 101 through a network and is used for randomly generating the identification two-dimensional code and sending the multimedia file. It should be noted that, in the embodiment of the present application, only a part of modules of the display are exemplarily given, and the display may further include other components included in other existing display devices to implement corresponding functions, which is not limited in particular.
Based on the elevator shown in fig. 1, as shown in fig. 2, the present embodiment provides a multimedia playing method based on two-dimensional code, including but not limited to steps S201, S202, S203, and S204:
s201, acquiring and playing the multimedia file.
It should be noted that the multimedia file in step S201 has two sources, one is to use a storage device to locally store multimedia data through a network, so as to perform validity authentication on the data before playing, and then to load the multimedia data into a memory of the display device when the display device can be installed and maintained. The other is distributed in streaming media format by the remote server 103 and played on the display 101. Streaming media refers to a technology and a process of compressing a series of media data, sending the data in segments on the network, and transmitting video and audio on the network in real time for viewing, wherein the technology enables data packets to be sent like streaming; if this technique is not used, the entire media file must be downloaded before use. The streaming transmission can transmit the live video or the film pre-stored in the server, and the video data is played by the specific playing software immediately after being sent to the terminal. The display 101 obtains the multimedia file and plays the multimedia file in the above manner.
S202, acquiring the identification two-dimensional code corresponding to the multimedia file.
In step S202, the step of obtaining the identification two-dimensional code corresponding to the multimedia file specifically includes the following steps:
judging whether the multimedia file is a local file or not; if so, randomly generating an identification two-dimensional code; otherwise, acquiring the identification two-dimensional code randomly generated by the server.
In this embodiment, it should be noted that, when the source of the multimedia file includes not only the locally stored multimedia file but also the streaming media sent by the server 103, the processor in the display 101 determines the source of the multimedia file to determine whether the multimedia file is a local file.
When the multimedia file is a local file, the processor in the display 101 obtains the secret information, such as a terminal serial number and an encryption key, and combines with available information such as the current time, then encrypts the secret information through a preset encryption algorithm, such as MD5 and SHAI, and then converts the encrypted secret information into a two-dimensional code. MD5 refers to MD5 message digest algorithm, a widely used cryptographic hash function, which can generate a 128-bit hash value to ensure the integrity of message transmission. The SHAI means that the Secure Hash Algorithm (Secure Hash Algorithm) is mainly applied to the Digital Signature Algorithm (Digital Signature Algorithm DSA) defined in the Digital Signature Standard (DSS). For messages less than 2^64 bits in length, SHA1 generates a 160-bit message digest. This message digest may be used to verify the integrity of the data when the message is received.
When the multimedia file is streaming media sent by the server 103, the server 103 randomly generates an identification two-dimensional code and sends the identification two-dimensional code to the display 101 together with the streaming media.
Alternatively, if the transmitted video is played fraudulently, and to avoid a situation in which the transmitted video fails to be played on the display screen 101 due to some kind of malfunction. In step S202, the step of obtaining the identification two-dimensional code corresponding to the multimedia file may further include the following steps:
randomly generating an identification two-dimensional code through a server and embedding the identification two-dimensional code into a multimedia file;
and extracting the identification two-dimensional code from the multimedia file.
In this embodiment, when the server 103 sends the multimedia file, the random identification two-dimensional code is synchronously generated by the above method, then the identification two-dimensional code is embedded into the multimedia file, and the multimedia file with the embedded two-dimensional code is sent to the display screen 101, and after the display screen 101 receives the file, the built-in processor extracts the identification two-dimensional code from the multimedia file. The fraudulent playing refers to a third-party playing device (the server and the playing terminal are not the same owner). By the method, the correctness of the content played by the display screen can be ensured under the condition that the transmitted video is played in a fraudulent mode or cannot be played by the display screen 101 due to certain faults, so that the terminal is trusted.
And S203, overlapping the identification two-dimensional code on the picture of the multimedia file for playing.
In this embodiment, when the multimedia file is played, the two-dimensional code is inserted and displayed on the screen. It is understood that the two-dimensional code may appear on the screen alone or may be superimposed on the screen for output. The skilled person can set the occurrence time of the two-dimensional code according to specific situations, such as the 10 th second of the multimedia file playing. The output time for recognizing the two-dimensional code does not need to be too long as the camera module 102 can capture the recognized two-dimensional code. The refreshing frequency of the system liquid crystal is above 60Hz, the playing preset time of the two-dimensional code can be set to 1/60 seconds, namely, the two-dimensional code is recognized to only occupy the time for playing one frame.
And S204, judging whether the two-dimension code is consistent with the standard two-dimension code, and stopping playing the multimedia file if the two-dimension code is inconsistent with the standard two-dimension code.
In step 204, the played two-dimensional identification code needs to be compared, and an image of the two-dimensional identification code is obtained first, then sent to the server 103, and compared with the standard two-dimensional code in the server 103. It can be understood that after the two-dimensional code image is acquired, the two-dimensional code can be further decoded, and finally, the data obtained after decoding is sent to the server 103 and compared with the standard data in the server 103. If the comparison result shows that the data in the identification two-dimensional code is different from the data in the server 103, the multimedia file is an illegal file, and the display screen 101 is immediately controlled to interrupt playing of the multimedia file or play the next multimedia file.
Optionally, before the step of determining whether the two-dimensional code is consistent with the standard two-dimensional code, the multimedia playing method based on the two-dimensional code according to the embodiment of the present application may further include the following steps:
controlling a two-dimensional code camera to acquire the identification two-dimensional code;
decoding the identification two-dimensional code through the two-dimensional code camera;
and acquiring the decoded identification two-dimensional code.
In this embodiment, the two-dimensional code camera needs to be arranged at a position where image information of the display can be acquired, the identification two-dimensional code is acquired by controlling the camera module 102, the identification two-dimensional code is decoded by a built-in processing module in the camera module 102, and then the decoded data is sent to the server 103 and compared with standard data in the server 103, so that the validity of the multimedia file is ensured. Specifically, the server 103 randomly generates an identification two-dimensional code according to the secret information and a preset algorithm and sends the two-dimensional code and the multimedia file to the display screen 101, and after receiving the multimedia file sent by the server 103, the display screen 101 superimposes the two-dimensional code on a picture of the multimedia file and plays the two-dimensional code together. When the identification two-dimensional code is played, the display screen 101 controls the camera module to acquire an image of the identification two-dimensional code played by the display screen 101, the identification two-dimensional code is decoded through a built-in processing module in the camera module 102, and then the decoded data is sent to the server 103 to be compared with standard data stored in the server 103, so that the legality of the multimedia file is judged.
Optionally, before the step of determining whether the two-dimensional code is consistent with the standard two-dimensional code, the multimedia playing method based on the two-dimensional code according to the embodiment of the present application may further include the following steps:
controlling a monitoring module to intercept a playing picture, wherein the monitoring module is connected with the server, and the playing picture comprises an identification two-dimensional code;
decoding the identification two-dimensional code on the playing picture;
and acquiring the decoded identification two-dimensional code.
In this embodiment, an independent monitoring module program may be added to the display 101, and the independent monitoring module program may communicate with the server 103 separately. The server 103 controls the monitoring module program to intercept the playing picture through the instruction, interprets the two-dimensional code on the picture, and returns the interpreted data to the server, so that the purpose of monitoring the playing content of the terminal is achieved. By the mode, one two-dimensional code camera can be saved, and the independent monitoring module program can be installed at various different playing terminals, so that the method is more favorable for on-site installation and transformation.

Illustratively, the server 103 randomly generates an identification two-dimensional code according to the secret information and a preset algorithm and sends the two-dimensional code together with the multimedia file to the display screen 101, and after receiving the multimedia file sent by the server 103, the display screen 101 superimposes the two-dimensional code on a picture of the multimedia file and plays the superimposed two-dimensional code. When the identification two-dimensional code is played, the display screen 101 controls the camera module to acquire an image of the identification two-dimensional code played by the display screen 101, the identification two-dimensional code is decoded through a built-in processing module in the camera module 102, and then the decoded data is sent to the server 103 to be compared with standard data stored in the server 103, so that the legality of the multimedia file is judged.
