And then the network data processing unit also submits the recovered pictures and characters to the information identification unit so that the information identification unit identifies and calculates the pictures and characters in the network data through a pre-stored information identification algorithm to identify whether the pictures and characters have bad contents, and feeds back the identification result to the network data processing unit.
The electronic screen information monitoring equipment provided by the embodiment of the invention not only can monitor network data in the process of sending programs to an electronic screen by the broadcasting control host, but also can access the video output interface of the broadcasting control host through a video cable, monitor the display of the broadcasting control host in real time through the video interface, monitor the programs in real time when the programs are edited in advance, find problems in time, cut off the network at the moment of sending a program, prohibit the broadcasting control host from sending data, monitor the broadcasting control interface and the sending programs in a double way in real time, and effectively avoid the possibility of bad content playing in time. The monitoring device is characterized in that the monitoring device is connected with the broadcast control host through the first network card and connected with the electronic screen receiving card through the second network card, data between the first network card and the second network card are required to be forwarded through a network data processing unit of the monitoring device, the monitoring device is designed by the double network cards, the broadcast control host and the electronic screen receiving card cannot be directly intercommunicated physically, the monitoring device is arranged between the broadcast control host and the unique connection of the electronic screen receiving card, all programs cannot be sent out by bypassing monitoring, all programs are issued under the control of the monitoring device, the monitoring device can prevent wrong playing of bad video contents caused by various reasons, the monitoring device can monitor network data of the broadcast control host in real time in the process of sending the programs, once the bad information is detected, network data transmission is immediately forbidden, the electronic screen receiving card cannot receive the bad information, and the possibility of the wrong playing of the bad contents can be effectively avoided in time. The monitoring equipment provided by the embodiment of the invention can automatically identify the network data, replaces manual auditing by a machine which is not tired, and can effectively avoid human errors.
For convenience of understanding, on the basis of the foregoing embodiment, an embodiment of the present invention further provides another electronic screen information monitoring device, where the network data processing unit, in addition to transmitting the network data acquired by the first network card from the broadcast control host to the second network card when the authentication result of the video stream is authentication pass, is further configured to: transmitting network data acquired by the first network card from the broadcast control host to the information identification unit; the information identification unit is also used for carrying out identification processing on the network data to obtain an identification result corresponding to the network data and feeding the identification result back to the network data processing unit; and the network data processing unit is also used for sending the network data to the second network card when the identification result of the network data is that the identification is passed, and sending the network data to the electronic screen unit through the second network card so that the electronic screen unit displays the display content included by the network data.
When the network data is acquired through the first network card, the program is processed by the network data processing unit and the information identification unit of the monitoring device. The network data processing unit is used for analyzing and processing the network data, recovering the picture information corresponding to the network data and transmitting the picture information to the information identification unit; the information identification unit is used for identifying the picture information according to a pre-stored information identification algorithm to obtain an identification result corresponding to the network data, and feeding the identification result back to the network data processing unit. After the information identification unit identifies the picture information of the network data, if the information identification algorithm does not find the bad content, the identification result corresponding to the picture information represents that the picture information is identified to be passed, and at the moment, the network data processing unit can completely forward all the network data to the appointed electronic screen receiving card through the second network card.
The network data processing unit transfers the network data formed by processing the video stream by the broadcast control host to the second network card when the video stream data passes the identification in the process of editing the electronic screen information, and also sends the network data to the second network card when the identification result of the network data is that the video stream data passes the identification.
Further, the information identification unit is also used for determining that the identification result is that the identification fails when any one of the character identification algorithm or the image identification algorithm fails to pass the identification; and the network data processing unit is also used for stopping sending the network data to the second network card when the identification result is that the identification is failed. The method specifically comprises the steps of stopping sending the network data to the second network card when the identification result of the network data is that the identification is not passed, and stopping forwarding the network data to the second network card when the identification result of the video stream is that the identification is not passed.
Specifically, if the information identification algorithm finds the bad content in the network data, the network data processing unit receives a feedback result that the network data identification does not pass, at this time, the network data processing unit stops forwarding the network data to the second network card, at this time, the network data will not be received by the electronic screen receiving card, and the bad video content can be prevented from being played. Furthermore, the monitoring equipment is configured with an operation and maintenance platform, and the network data processing unit can also feed back network data exception reminding to the user through the operation and maintenance platform based on the identification and the feedback, so that the user can process the network data in the broadcast control host in time until the internal operation and maintenance platform of the monitoring equipment is recovered manually, and the network data processing unit can continue to execute work.
In a specific implementation, the video capture unit may include an HDMI video capture card, and the broadcast control host needs to edit programs on the broadcast control host manually at present. The content of the program can be seen through the display of the broadcast control host, and the content of the program can be sent to the electronic screen. Therefore, the embodiment of the invention can also collect the video stream sent by the broadcast control host to the display of the broadcast control host through the video collecting unit so as to monitor the video stream in the process of editing programs by the broadcast control host. Specifically, because the broadcast control host is connected with the broadcast control host player through the video cable, at the moment, the video converter can be installed on the video cable and connected with the video converter through the video acquisition unit, so that the video acquisition unit of the monitoring equipment can acquire the same picture as the display of the broadcast control host. When the video acquisition unit acquires the video stream corresponding to the broadcast control host, the video acquisition unit can periodically acquire pictures through the video acquisition card to generate pictures.
Furthermore, the video acquisition unit provided in the embodiment of the present invention may be implemented by the following method according to actual conditions, except that a standard HDMI interface is used to acquire a video stream of the broadcast control host, and a video converter is used to divide a video into one path to access the monitoring device to acquire a display interface of the broadcast control host: a. if the broadcasting control host has a plurality of video interfaces, the video converter can be omitted, and the video interfaces are directly connected with the video acquisition unit; b. if the video interface of the broadcast control host is VGA, SDI, DVI, AV, RAC and other interfaces, the video interface can be converted into HDMI for access through the converter. In addition, the pictures of the display of the broadcast control host can be acquired by screen capturing plug-in, screen recording, monitoring and the like, and then transmitted to the video acquisition unit in an Ethernet, bluetooth, wireless and other modes. The embodiment of the invention introduces the acquisition interface of the video acquisition unit as a standard HDMI, the acquisition interface of the video acquisition unit can be changed into various types of interfaces such as standard VGA, SDI, DVI and the like by replacing the video acquisition card, and the HDMI can be adapted to the display interfaces of most broadcasting control hosts.
Further, the first network card and the second network card provided by the embodiment of the present invention access the network corresponding to the broadcast control host in the form of ethernet ports, where the first network card and the second network card may also access through wireless network, optical fiber, USB and other network cards, 4G, 5G and other ways, and in addition, the monitoring device provided by the embodiment of the present invention may also support the scenes of serial ports, 485 and other communication ways after the connection interface is replaced. The first network card and the second network card provided by the embodiment of the invention are realized in a standard Ethernet interface mode, and can be directly adapted to most broadcast control host computers and electronic screen receiving card interfaces.
Further, the information identification unit is also used for determining that the identification result is that the identification is not passed when any one of the character identification algorithm or the image identification algorithm is not passed; and the network data processing unit is also used for stopping sending the network data to the second network card when the identification result is that the identification is failed.
In addition, the video acquisition unit is further configured to acquire video data at a video acquisition interface corresponding to the video converter, and when the video data indicates an invalid video, the network data processing unit stops sending the network data to the second network card.
When the video acquisition unit acquires the video stream of the broadcast control host, the video acquisition card can be used for acquiring the video state so as to detect whether the acquisition interface receives effective video data or not, the video data at the video acquisition interface generally carries video parameters, the video parameters carry information representing whether the video is effective data or not, and the video acquisition unit can determine whether the video data is effective data or not through the information. When the acquisition card does not receive an effective video state, the acquisition interface corresponding to the video acquisition unit is considered to have no access to a video source, namely, the acquired video data is invalid data, at the moment, the network data processing unit also stops sending the network data to the second network card, and the network data corresponding to programs sent by the subsequent broadcast control host cannot be forwarded to the electronic screen receiving card, so that the situation that the monitoring equipment detection is skipped manually by pulling out a video line is avoided until the video line is manually recovered and recovered through an operation and maintenance platform in the equipment is avoided. When the network data processing unit receives the feedback that the identification result of the network data or the video stream is characterized as that the identification is not passed and the invalid instruction, the network data processing unit alarms through an operation and maintenance platform in the network data processing unit, and in addition, the monitoring equipment triggers the alarm when detecting any problem.
Furthermore, the functions corresponding to the information identification unit and the network data processing unit of the monitoring device provided by the embodiment of the invention can also be integrated in the electronic screen receiving card according to requirements, and the network data sent by the broadcast control host computer is subjected to data monitoring through the electronic screen receiving card; in addition, the above functions can also be integrated in the broadcast control host, and the effect which can be realized by the information authentication unit and/or the network data processing unit can be realized by the broadcast control host. Further, the video acquisition unit, the network data processing unit and the information identification unit can also be respectively deployed in independent hardware modules, and corresponding functions are realized through communication among a plurality of hardware modules.
Specifically, the information identification unit is configured with an algorithm database, the algorithm database stores information identification algorithms in advance, the information identification algorithms comprise a character identification algorithm and an image identification algorithm, and the information identification unit is also used for acquiring the character identification algorithm and/or the image identification algorithm to perform identification processing on the image information and/or the character information; and if the character identification algorithm and/or the image identification algorithm are identified to pass, determining that the identification result is identification to pass.
Wherein, the character identification algorithm is also provided with a sensitive word stock; when the information identification unit identifies the network data or the video stream in a character mode, the character information in the picture information corresponding to the corresponding network data can be extracted, and the character information is identified through a character identification algorithm, for example, the character information is compared with a pre-stored sensitive word bank through the character identification algorithm; judging whether sensitive words meeting a word threshold corresponding to the word information exist in the sensitive word bank or not; if so, the text message authentication is determined not to pass.
Specifically, the embodiment of the present invention may use techniques such as NLP, fuzzy matching, neural network algorithm, semantic segmentation, etc. to identify one or more of fuzzy matching, pinyin matching, and synonym matching between the extracted text information and the sensitive lexicon, so as to determine whether a sensitive word satisfying a text threshold corresponding to the text information exists in the sensitive lexicon. The sensitive word bank stores various vocabularies such as pornography, abuse, political affairs and the like, and the picture and the words are regarded as bad information by the information identification algorithm when the picture and the words are found to be matched with any vocabulary in the sensitive word bank.
When the information identification unit identifies the network data or the video stream, the network data processing unit is further used for analyzing the network data, recovering picture information corresponding to the network data, and transmitting the picture information to the information identification unit, wherein the picture information comprises image information and/or character information, the information identification unit is used for extracting the picture information in the picture information corresponding to the network data, key information in the picture information is extracted through an image analysis technology, a plurality of image areas to be analyzed corresponding to the picture information are obtained, each image area to be analyzed is input into a preset deep learning model, the image area to be analyzed is analyzed, and whether the image area to be analyzed comprises bad information corresponding to the image or not is detected.
