[0047] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the present disclosure or its application or use.

[0051] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0052] The inventors noted that in related technologies, there is piracy during content playback, but due to the lack of a reasonable monitoring scheme, the information publishing system cannot publish the information as expected according to business needs.

[0053] In view of the above, the present disclosure proposes the following technical solutions.

[0054] Figure 1 This is a schematic diagram of the structure of an information publishing system according to some embodiments of the present disclosure.

[0055] like Figure 1 As shown, in some embodiments, the information publishing system includes a server 101 and a broadcast control terminal 102. The server 101 interacts with the broadcast control terminal 102 via a network. For example, the network includes a wide area network, a local area network, or a private network. For example, the network includes a wireless network. The server 101 can be any of the servers provided in the following embodiments, and the broadcast control terminal 102 can be any of the broadcast control terminals provided in the following embodiments.

[0056] In other embodiments, the information publishing system further includes one or more display terminals 103, such as liquid crystal displays (LCDs) or light-emitting diode (LED) displays. In still other embodiments, the information publishing system further includes a web (worldwide web) platform 104.

[0057] The following is a brief introduction to the working process of the information publishing system.

[0058] On the web platform 104, program production and playback scheduling can be performed based on original media materials (such as text, images, and videos), and the broadcast control terminal 102 can be determined. In response to a request from the web platform 104, the server 101 sends the program's media materials (such as the media materials of all programs in the playback schedule) to the broadcast control terminal 102. The broadcast control terminal 102 then controls the corresponding display terminal 104 to play the corresponding program according to the predetermined playback time.

[0059] In order to effectively monitor the content played on the display terminal 103, this embodiment of the disclosure proposes to generate a code (also known as a monitoring identifier code or short code) for monitoring based on program information. The following description, in conjunction with different embodiments, will illustrate this.

[0060] Figure 2 This is a schematic flowchart of a monitoring method according to some embodiments of the present disclosure. For example, the monitoring method can be executed by server 101.

[0061] In step 202, a monitoring identifier code for the program is generated based on the business information. Here, the business information includes first information related to the program.

[0062] For ease of distinction, information related to the program is referred to as first information. In some embodiments, first information includes one or more types of information, such as at least one of identification information and time information. The following description will illustrate different embodiments.

[0063] In some embodiments, the service information also includes other information, such as second information related to the broadcast control terminal. As some implementations, the second information includes the identification information of the broadcast control terminal.

[0064] In some embodiments, the monitoring identifier is business information in the form of a string, that is, the monitoring identifier consists of a string corresponding to each piece of information in the business information.

[0065] In step 204, a first watermark image is generated based on the monitoring identifier code. For example, the first watermark image is a transparent watermark image.

[0066] In some embodiments, the monitoring identifier code is encoded to obtain another identifier code, and a first watermark image is generated based on the encoded other identifier code. For example, the monitoring identifier code is encoded using ASCII (American Standard Code for Information Interchange) functions to obtain ASCII as another identifier code. It should be understood that the embodiments of this disclosure are not limited thereto, and other encoding methods can also be used to encode the monitoring identifier code.

[0067] In some embodiments, a first watermark image is generated using a predetermined watermarking algorithm based on the monitoring identifier code and the screen resolution of the display terminal that needs to play the program. In this way, the resolution of the first watermark image matches the screen resolution of the display terminal, resulting in better display quality.

[0068] In step 206, the media material of the program and the first watermark image are sent to the broadcast control terminal so that the media material with the first watermark image can be played. For example, when playing the media material, the broadcast control terminal controls the playback to place the first watermark image on top.

[0069] In some embodiments, the media material of each program in the broadcast schedule to which the program belongs, along with the first watermark image, is sent to the broadcast control terminal.

[0070] In some embodiments, the physical address of the broadcast control terminal, such as the MAC (Media Access Control) address, is determined based on the identifier of the broadcast control terminal, and then the media material of the program and the first watermark image are sent to the broadcast control terminal based on the MAC address.

[0071] In step 208, a screenshot image is received from the broadcast control terminal. Here, the screenshot image is an image captured during the playback of content on the display terminal. In other words, the screenshot image is a screenshot from the display terminal.

[0072] For example, screenshots may be captured by the broadcast control terminal; or screenshots may be captured by other components and then sent to the broadcast control terminal. In some embodiments, a screenshot is captured at predetermined intervals, such as one minute, two minutes, etc. In some embodiments, the received screenshots are images compressed from the initial screenshots obtained by the broadcast control terminal.

[0073] In step 210, monitoring is performed based on the screenshot image and the monitoring identification code.

[0074] Under normal playback conditions, the display terminal plays media material with the first watermark image. Therefore, the first watermark image can be obtained from a screenshot of the display terminal, and then the monitoring identifier code can be obtained from the obtained first watermark image. Subsequently, based on the monitoring identifier code obtained from the screenshot and the monitoring identification code generated in step 204, it can be determined whether the display terminal is playing normally according to the playback plan.

[0075] In the above embodiment, a monitoring identifier code for the program is generated based on program-related information, and the program's media materials and a first watermark image generated based on the monitoring identifier code are sent to the broadcast control terminal for playback. Subsequently, monitoring is performed based on screenshots captured during the playback process on the display terminal and the previously generated monitoring identifier code. Since program-related information represents the characteristics of the program itself and changes with different programs, the monitoring identifier code generated based on the program-related information is not easily cracked. Thus, using such a monitoring identifier code, the content played on the display terminal can be accurately monitored.

[0076] Understandably, following the above method, different monitoring identifiers can be generated for multiple programs. For example, a first monitoring identifier is generated for the first program, and a second monitoring identifier is generated for the second program. The display terminal may be playing either the first program or the second program. By using screenshots captured during playback on the display terminal, along with the previously generated first and second monitoring identifiers, the content played on the display terminal can be monitored.

[0077] The following describes the first information related to the program in conjunction with different embodiments.

[0078] In some embodiments, the first information related to the program includes one or more of the following: program playback time information, sub-information related to the playback schedule to which the program belongs, and program identifier.

[0079] In this way, the monitoring identification code generated based on the first information is less likely to be cracked, thus enabling more accurate monitoring of the content played on the display terminal.

[0080] As some implementation methods, the first information includes any one of the following: program playback time information, sub-information related to the program's playback schedule, and program identifier. For example, the first information may include the program identifier; or it may include sub-information related to the program's playback schedule; or it may include the program's playback time information. Considering either the sub-information related to the program's playback schedule or the program's playback time information, the generated monitoring identifier is less likely to be cracked, thus enabling more accurate monitoring of the content played on the display terminal.

[0081] In other implementations, the first information may include multiple, such as two or three, of the following: program broadcast time information, sub-information related to the program's broadcast schedule, and program identifier. For example, the first information may include program broadcast time information and sub-information related to the program's broadcast schedule; or, for another example, the first information may include program broadcast time information and program identifier; or, even more specifically, the first information may include program broadcast time information, sub-information related to the program's broadcast schedule, and program identifier.

[0082] In the above implementation, the first information includes multiple pieces of information mentioned above. Therefore, the monitoring identifier generated based on the first information is less likely to be cracked, thus enabling more accurate monitoring of the content played on the display terminal.

[0083] For example, if the first information includes the program's playback time information and the program's identifier, even if different programs have the same identifier, the generated monitoring identifier codes will be different, thereby enabling more accurate monitoring of the content played on the display terminal.

[0084] For example, if the first information includes the program's playback time information and the program's identifier, even if different programs have the same identifier, the generated monitoring identifier codes will be different, thereby enabling more accurate monitoring of the content played on the display terminal.

[0085] The following describes some examples of sub-information related to the broadcast schedule to which the program belongs.

[0086] In some embodiments, the sub-information related to the playback schedule to which the program belongs includes at least one of the playback schedule identifier and the playback schedule type. For example, the sub-information includes both the playback schedule identifier and the playback schedule type to further increase the difficulty of cracking the monitoring identifier code, thereby enabling more accurate monitoring of the content played on the display terminal.

[0087] For example, a broadcast schedule may correspond to one or more programs. In other words, different programs may belong to the same broadcast schedule.

[0088] As some implementation methods, the playback schedule is either a regular schedule or a filler schedule. It should be understood that programs corresponding to a regular schedule will be played according to the schedule (e.g., according to a planned playback time range); programs corresponding to a filler schedule will be played when no programs corresponding to the regular schedule are broadcast, for example, when programs corresponding to the regular schedule fail to play normally.

[0089] The following section introduces some examples of program playback time information.

[0090] In some embodiments, the program's playback time information includes at least one of the following: the start timestamp of the playback schedule to which the program belongs, the start timestamp of the program itself, the end timestamp of the program, and the program's creation time. Considering such playback time information can further increase the difficulty of cracking the monitoring identifier, thereby enabling more accurate monitoring of the content played on the display terminal.

[0091] In some implementations, the program's playback time information includes any one of the following: the start timestamp of the playback schedule to which the program belongs, the start timestamp of the program itself, the end timestamp of the program, and the program's creation time. For example, the program's playback time information may include the start timestamp of the playback schedule to which the program belongs; or, for another example, it may include the program's creation time. It should be understood that when a playback schedule corresponds to multiple programs, the start timestamp of the playback schedule is the start timestamp of the program with the earliest start timestamp among the multiple programs corresponding to the playback schedule.

[0092] In other implementations, the program's playback time information includes multiple timestamps, such as two, three, or four: the start timestamp of the program's playback schedule, the start timestamp of the program itself, the end timestamp of the program, and the program's creation time. This further increases the difficulty of cracking the monitoring identifier, thereby enabling more accurate monitoring of the content played on the display terminal.

[0093] In some embodiments, the program's playback time information is related to the type of playback schedule to which the program belongs. This will be described below with reference to some embodiments.

[0094] For ease of description, in the following text, when the program belongs to a normal program, the program's playback time information will be referred to as the first playback time information; and when the program belongs to a filler program, the program's playback time information will be referred to as the second playback time information.

[0095] In some embodiments, the second playback time information differs from the first playback time information. Thus, for both regular and padding schedules, a monitoring identifier is generated based on the different playback time information, further increasing the difficulty of cracking the monitoring identifier and enabling more accurate monitoring of the content played on the display terminal.

[0096] In some implementations, the first playback time information includes at least one, or one or more, of the start timestamp of the playback schedule to which the program belongs, the start timestamp of the program itself, and the end timestamp of the program. In other implementations, the second playback time information includes the program's creation time. This approach further increases the difficulty of cracking the monitoring identifier code of programs corresponding to ordinary schedules or filler schedules, thereby enabling more accurate monitoring of program content corresponding to ordinary schedules or filler schedules played on the display terminal.

[0097] As another implementation, the first playback time information includes at least one of the start timestamp of the playback schedule to which the program belongs, the start timestamp of the program itself, and the end timestamp of the program; and the second playback time information includes the program's creation time. This further increases the difficulty of cracking the monitoring identifier codes of programs corresponding to the regular schedule and the filler schedule, thereby enabling more accurate monitoring of the program content corresponding to the regular schedule and the filler schedule played on the display terminal.

[0098] In some embodiments, the first playback time information is the start timestamp of the playback schedule to which the program belongs. In this way, when the playback schedule corresponds to multiple programs, when generating a monitoring identifier for each program, it is not necessary to look up the playback timestamp of each program separately. Instead, it is only necessary to use the start timestamp of the playback schedule, which reduces the probability of errors when generating the monitoring identifier and thus enables more reliable monitoring of the content played on the display terminal.

[0099] Figure 3 This is a schematic flowchart of a monitoring method according to other embodiments of the present disclosure. For example, the monitoring method may be executed by server 101. Figure 3 The illustrated embodiments and Figure 2 The relevant aspects of the illustrated embodiments can be referred to in the above description, and will not be repeated here.

[0100] In step 302, a monitoring identifier code for the program is generated based on the business information. Here, the business information includes the program's playback time information, the identifier of the playback plan to which the program belongs, the type of playback plan, and the program's identifier.

[0101] In some embodiments, the service information may also include the identifier of the broadcast control terminal.

[0102] For example, a monitoring identification code consists of a string of the following information: the identifier of the broadcast control terminal, the program's playback time information (e.g., in seconds), the identifier of the playback schedule to which the program belongs, the type of playback schedule, and the program's identifier. The order of the different information strings in the monitoring identification code is not limited. For example, they can be arranged in the order described above.

[0103] In step 304, a first watermark image is generated based on the monitoring identification code.

[0104] In step 306, the media material of the program and the first watermark image are sent to the broadcast control terminal so that the broadcast control terminal can control the display terminal to play the media material with the first watermark image.

[0105] In step 308, a screenshot image is received from the broadcast control terminal. Here, the screenshot image is an image captured by the broadcast control terminal while the content is being played on the display terminal.

[0106] In step 310, monitoring is performed based on the screenshot image and the monitoring identification code.

[0107] In the above embodiments, a monitoring identifier code for the program is generated based on the program's playback time information, the identifier of the playback plan to which the program belongs, the type of the playback plan, and the program's identifier. The program's media materials and a first watermark image generated based on the monitoring identifier code are then sent to the broadcast control terminal for playback. Subsequently, monitoring is performed based on screenshots taken during the playback process on the display terminal and the previously generated monitoring identifier code. This method makes the generated monitoring identifier code more difficult to crack. Thus, using such a monitoring identifier code allows for more accurate monitoring of the content played on the display terminal.

[0108] The following examples illustrate how to implement monitoring based on screenshots and monitoring identifiers.

[0109] Figure 4 This is a flowchart illustrating some implementation methods for monitoring based on screenshots and monitoring identifiers.

[0110] In some embodiments, see Figure 4 The steps for monitoring based on screenshots and monitoring identification codes include steps 402, 404, 406, and 408.

[0111] In step 402, the second watermark image is parsed from the screenshot image.

[0112] In some embodiments, after parsing the second watermark image, the ASCII code is obtained from the second watermark image, and then the monitoring identifier code is obtained by using the ASCII inversion function.

[0113] In step 404, it is determined whether the monitoring identifier code has been obtained based on the second watermark image.

[0114] If not, that is, if the monitoring identifier code generated previously (generated in step 204 or step 304) cannot be obtained from the second watermark image, proceed to step 406.

[0115] In step 406, the error count for the broadcast control terminal is incremented by one. For example, the initial value of the error count for the broadcast control terminal is 0.

[0116] Subsequently, the number of errors on the broadcast control terminal can be used to determine whether to issue an alarm.

[0117] In step 408, an alarm is issued if the number of errors for the broadcast control terminal exceeds a first preset number. It should be understood that the first preset number is greater than or equal to 1. In some embodiments, the web platform may display alarm information.

[0118] In the above embodiment, if the previously generated monitoring identifier code cannot be obtained from the second watermark image, the error count for the broadcast control terminal is incremented by one. An alarm is only triggered if the error count for the broadcast control terminal exceeds a first preset count. This avoids erroneous alarms caused by the inability to obtain the monitoring identifier code due to poor screenshot image quality, thus enabling accurate monitoring of the content played on the display terminal.

[0119] In some other embodiments, the step of monitoring based on the screenshot image and the monitoring identifier code further includes step 410.

[0120] In step 410, if the number of errors for the broadcast control terminal exceeds a second preset number, the broadcast control terminal is notified to stop playback on the display terminal. The second preset number is greater than the first preset number. For example, the first preset number is 5 and the second preset number is 10.

[0121] For example, if the number of errors on the broadcast control terminal exceeds a second preset number, the broadcast control terminal is notified to control the display terminal to turn off the screen.

[0122] In some embodiments, after generating the monitoring identifier code, the corresponding record information is stored. This record information includes the monitoring identifier code and the program's identifier. For example, the record information is stored in a record table. In some embodiments, a user can view the record information; in other embodiments, a user can modify the information in the record information.

[0123] The recorded information may also include other information. In some implementations, the recorded information may also include the identifier of the broadcast control terminal. In other implementations, the recorded information may include one or more of the following: primary key, identifier of the playback plan to which the program belongs, type of playback plan, generation time of the monitoring identification code, number of successful monitoring verifications, and monitoring verification success time. In still other implementations, the recorded information may also include remarks. For example, the remarks of the recorded information may store information about the alarm triggered in step 408, such as the alarm time; or, for example, the remarks of the recorded information may store information about notifying the broadcast control terminal to stop playback in step 410, such as the notification time.

[0124] In the case of storing record information, see Figure 4 If the result of step 404 is yes, then step 412 is executed.

[0125] In step 412, the program identifier is retrieved from the record information corresponding to the monitoring identifier code.

[0126] For example, a screenshot may contain the MAC address of the broadcast control terminal. The terminal's identifier can be found using this MAC address. In this case, the program's identifier can be retrieved from the recorded information using the monitoring identifier obtained from the screenshot and the found broadcast control terminal identifier, thus making the program's identifier more accurate.

[0127] In step 414, it is determined whether the server's current system time is within the planned playback time range of the program. If not, i.e., the server's current system time is not within the planned playback time range of the program, then return to step 406. In some embodiments, if yes, i.e., the server's current system time is within the planned playback time range of the program, then step 416 is executed.

[0128] In step 416, the error count for the broadcast control terminal is reset to zero.

[0129] In the above embodiments, if the monitoring identifier code cannot be obtained from the second watermark image, the error count for the broadcast control terminal is incremented by one. Similarly, if the server's current system time is outside the planned playback time of the program, the error count for the broadcast control terminal is also incremented by one. This allows for more effective monitoring of the content played on the display terminal.

[0130] In some embodiments, the recorded information includes the type of playback plan to which the program belongs. If the type is a normal plan, step 412 is performed; if the type is a padding plan, step 412 is not performed. This reduces the processing load on the server.

[0131] The above describes monitoring methods that can be executed by a server, with reference to different embodiments. Below are some monitoring methods that can be executed by a broadcast control terminal, with reference to some embodiments.

[0132] Figure 5 This is a schematic flowchart of a monitoring method according to some embodiments of the present disclosure. For example, the monitoring method can be executed by the broadcast control terminal 102.

[0133] In step 502, the program's media material and a first watermark image are received from the server. Here, the first watermark image is generated by the server based on a monitoring identifier, which is generated by the server based on service information. The service information includes one or more of the following: program playback time information, the identifier of the playback plan to which the program belongs, the type of playback plan, and the program's identifier.

[0134] In step 504, the control display terminal plays media material with the first watermark image.

[0135] In step 506, a screenshot is captured while the content is playing on the display terminal.

[0136] It should be understood that, under normal circumstances, the display terminal will play media materials with the first watermark image under the control of the broadcast control terminal. If piracy occurs, the content played by the display terminal will no longer be the content expected to be played under the control of the broadcast control terminal.

[0137] In step 508, the screenshot is sent to the server so that the server can monitor the broadcast based on the screenshot and the monitoring identifier code. The server can perform monitoring as described above, which will not be repeated here.

[0138] In the above embodiments, after receiving the media material and the first watermark image of the program from the server, a screenshot of the content being played on the display terminal is sent to the server so that the server can monitor the playback based on the screenshot and the previously generated monitoring identifier. The monitoring identifier generated based on one or more of the program's playback time information, the identifier of the playback plan to which the program belongs, the type of the playback plan, and the program's identifier is not easily cracked. In this way, the content played on the display terminal can be accurately monitored.

[0139] Figure 6 This is a schematic flowchart of a monitoring method according to some embodiments of the present disclosure. For example, the monitoring method can be executed by a broadcast control terminal 102. Figure 6 The illustrated embodiments and Figure 5 The relevant aspects of the illustrated embodiments can be referred to in the above description, and will not be repeated here.

[0140] In step 602, the media material of the program and the first watermark image are received from the server.

[0141] In step 604, the display terminal is controlled to play media material with the first watermark image.

[0142] In step 606, a first monitoring identifier code is generated based on the service information. Here, the service information includes one or more of the following: the playback time information of the program that the broadcast control terminal should control the display terminal to broadcast according to the plan; the identifier of the playback plan to which the program belongs; the type of the playback plan; and the identifier of the program.

[0143] It is understandable that the broadcast control terminal and the server generate monitoring identification codes according to the same preset rules. In other words, based on the same business information, the monitoring identification code generated by the broadcast control terminal is the same as the monitoring identification code generated by the server.

[0144] In step 608, a screenshot is captured while the content is playing on the display terminal.

[0145] In step 610, the second watermark image is parsed from the screenshot image.

[0146] In some embodiments, if no watermark image is found in the screenshot, the display terminal is controlled to stop playing.

[0147] In step 612, the second monitoring identifier code is obtained based on the second watermark image.

[0148] In some embodiments, if no monitoring identifier code can be obtained from the second watermark image, the control display terminal stops playing.

[0149] In step 614, monitoring is performed based on the first monitoring identifier code and the second monitoring identifier code.

[0150] The following describes some implementation methods for monitoring based on the first monitoring identifier and the second monitoring identifier.

[0151] In some implementations, if the first monitoring identifier code and the second monitoring identifier code are inconsistent, the error count for the broadcast control terminal is incremented by one; if the error count for the broadcast control terminal is greater than a third preset count, the display terminal is controlled to stop playback, for example, the display terminal is controlled to turn off the screen.

[0152] In the above embodiments, after receiving the media material and the first watermark image of the program from the server, the broadcast control terminal generates a monitoring identification code based on one or more of the following: the playback time information of the program that should be broadcast according to the schedule, the identifier of the playback plan to which the program belongs, the type of the playback plan, and the program identifier. The terminal then monitors the program based on the screenshot image and the generated monitoring identification code. Such a monitoring identification code is difficult to crack. In this way, the content played on the display terminal can be accurately monitored.

[0153] Figure 7 This is a schematic flowchart of a monitoring method according to some embodiments of the present disclosure. For example, the monitoring method can be executed by a broadcast control terminal 102. Figure 7 The illustrated embodiments and Figure 5 and Figure 6 The relevant aspects of the illustrated embodiments can be referred to in the above description, and will not be repeated here.

[0154] In step 702, the media material of the program and the first watermark image are received from the server.

[0155] In step 704, the control display terminal plays media material with the first watermark image.

[0156] In step 706, a first monitoring identifier code is generated based on the business information. Here, the business information includes one or more of the following: program playback time information, the identifier of the playback plan to which the program belongs, the type of the playback plan, and the program identifier.

[0157] In step 708, a screenshot is captured while the content is playing on the display terminal.

[0158] In step 710, determine whether the network between the broadcast control terminal and the server is normal. If yes (i.e., the network between the broadcast control terminal and the server is not disconnected and communication is normal), proceed to step 712; if no (i.e., the network between the broadcast control terminal and the server is disconnected and communication is abnormal), proceed to steps 714-718.

[0159] In step 712, the screenshot image is sent to the server so that the server can monitor the broadcast based on the screenshot image and the monitoring identifier code.

[0160] In step 714, the second watermark image is parsed from the screenshot image.

[0161] In step 716, the second monitoring identifier code is obtained based on the second watermark image.

[0162] In step 718, monitoring is performed based on the first monitoring identifier code and the second monitoring identifier code.

[0163] In the above embodiments, when the network between the broadcast control terminal and the server is normal, the server monitors the broadcast based on the screenshot and the previously generated monitoring identification code; when the network between the broadcast control terminal and the server is abnormal, the broadcast control terminal monitors the broadcast based on its own generated monitoring identification code and the screenshot. Thus, on the one hand, when the network is normal, the server prioritizes monitoring, eliminating the need for the broadcast control terminal to generate an additional monitoring identification code, reducing the burden on the broadcast control terminal; on the other hand, even if the network is abnormal, the content played on the display terminal can still be accurately monitored.

[0164] It should be understood that the monitoring methods of the different embodiments described above can be combined with each other to obtain a monitoring method executed by the server and the broadcast control terminal.
