[0037] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The information push method described in the preferred embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the information push method includes the following steps:

[0039] Step S10: The controller receives the audio and video stream text and scrolling subtitle text uploaded by the upload display, and stores them in the on-demand library after classification.

[0040] Specifically, from Figure 2 It can be seen that the information push system of the present invention includes a controller, a plurality of intelligent display terminals ( Figure 2 The controller is connected to the multiple intelligent display terminals, the upload display and the management display respectively, wherein the multiple intelligent display terminals are used to play audio and video streams or scrolling subtitles according to the control instructions of the controller, the upload display is used to upload the audio and video stream text and scrolling subtitle text of the propaganda, and the management display is used to review the audio and video stream text and scrolling subtitle text in the on-demand library, and check the rationality of the push plan of the intelligent display terminal.

[0041] The uploading display can upload audio and video stream texts and scrolling subtitles texts for education, and can play the uploaded audio and video stream texts and scrolling subtitles texts at the same time. Then the uploading display transmits the uploaded audio and video stream texts and scrolling subtitles texts for education to the controller. The controller classifies the audio and video stream texts and scrolling subtitles texts for education and stores them in the on-demand library. That is to say, the controller has an on-demand library, which can be used to save the classified audio and video stream texts and scrolling subtitles texts for education uploaded by the uploading display. In addition, the on-demand library is actually a media library. As long as it is legal and compliant multimedia resources (such as audio, video, pictures, etc.), they can be saved. That is, the on-demand library not only saves audio and video stream texts and scrolling subtitles texts, but also other resources, which is similar to a resource database.

[0042] Furthermore, before step S10, the controller numbers different target scenes (the target scene of the present invention takes a hospital ward as an example, and may also be other scenes, such as classrooms, libraries, gymnasiums, conference rooms, waiting rooms, etc.) and smart display terminals set in different target scenes, for example Figure 3 The ward numbers in the ward are: ward 1, ward 2, ..., ward m (m represents a positive integer), the TVs in the wards are numbered: TV 1 and TV 2 in ward 1, TV 3, TV 4 and TV 5 in ward 2, ..., TV n-1 and TV n in ward m (n represents a positive integer), and an association table between different target scenes and the corresponding intelligent display terminals set in the target scenes is established. The association table can be updated in real time according to the changes of the TV or wards and beds, such as the "Association Table of TVs and Wards / Beds", for example Figure 3 As shown, the beds are numbered 501, 502, and 503, and ward 501 is provided with beds No. 1, No. 2, No. 3, No. 4, No. 5, and No. 6. Beds No. 1, No. 2, and No. 3 in ward 501 correspond to TV No. 1, and beds No. 4, No. 5, and No. 6 in ward 501 correspond to TV No. 2. Beds No. 1 and No. 2 are provided in ward 502, and beds No. 1 and No. 2 in ward 502 correspond to TV No. 3. Beds No. 1, No. 2, and No. 3 are provided in ward 503, and beds No. 1, No. 2, and No. 3 in ward 503 correspond to TV No. 4. In this way, a corresponding association table of different wards, beds, and TVs is established; the controller queries the corresponding smart display terminal according to the number of the target scene based on the association table of the corresponding relationship between the target scene and the smart display terminal, for example Figure 3 In the example, it can be found that the TV corresponding to bed No. 4 of bed 501 is TV No. 2 according to bed No. 4 of bed 501.

[0043] Step S20: After the management display has reviewed and approved the contents in the on-demand library, the controller receives an on-demand instruction issued by a user in the target scene through a smart display terminal.

[0044] Specifically, Figure 2 The management display in is connected to the controller. The management display can be used to display audio and video streams or scrolling subtitles, and is also used to check (review) the audio and video stream texts and scrolling subtitles texts for education uploaded to the controller by the upload display. For example, the management display reviews whether the audio and video stream texts and scrolling subtitles texts are compliant, legal, and appropriate (for example, whether they are convenient for patients in the ward to watch, such as whether they are the playback content for rehabilitation and physiotherapy of seriously ill patients in the ward for a certain disease). It can also check whether the push plan of the upload display (the push plan formulated by the upload display) is reasonable, and approve whether it can be pushed to the smart display terminal (such as the TV in the ward). The management display can also check whether the resource content in the on-demand library of the controller is compliant, and approve whether it can be played on demand; the management display can also check the on-demand records and perform corresponding data management and analysis.

[0045] Then, after the management display has reviewed and approved the contents in the on-demand library in the controller, the controller receives on-demand instructions issued by users in the target scene through the intelligent display terminal. For example, the controller receives on-demand instructions issued by patients in a hospital ward through a TV set in front of the patient's bed. For example, a diabetic patient sends a request through the TV to watch a video on how to take precautions for a diabetic diet. In this case, the controller can receive the request issued by the patient.

[0046] Step S30: The controller controls the specified intelligent display terminal in the target scene to switch the current playing content to the specified audio and video stream or add scrolling subtitles to the current playing content for playback according to the on-demand instruction.

[0047] For detailed process, please refer to Figure 4 , which is a flowchart of step S30 in the information push method provided by the present invention.

[0048] like Figure 4 As shown, the step S30 includes:

[0049] S31, after receiving the on-demand instruction, the controller searches for the smart display terminal specified in the target scene according to the association table of the correspondence between the target scene and the smart display terminal;

[0050] S32, the controller controls the specified smart display terminal in the target scene to stop playing the current playing content, and switches the current playing content to the specified audio and video stream for playing;

[0051] S33: The controller controls the designated smart display terminal in the target scene to add scrolling subtitles to the current playing content and play it synchronously without affecting the current playing content.

[0052] Specifically, the controller receives a video-on-demand instruction issued by a user in the target scene through the intelligent display terminal, and retrieves the association table of the correspondence between the target scene and the intelligent display terminal that has been established in advance, such as Figure 3 As shown in the association table, for example, the patient in bed No. 1 of ward 502 sends a command on demand to watch heart disease precautions through the remote control of TV No. 3, then the controller knows that TV No. 3 corresponding to the patient in bed No. 1 of ward 502 needs to play the relevant content of heart disease precautions. At this time, there are two ways for the controller to play the relevant content of heart disease precautions. The first is that the controller controls TV No. 3 corresponding to bed No. 1 of ward 502 to stop playing the current playing content (for example, if today's news is currently being played, then the playing of today's news is interrupted), and switches the currently playing today's news to the designated heart disease precautions video, and plays the heart disease precautions video. The second is that the controller controls TV No. 3 corresponding to bed No. 1 of ward 502 to add scrolling subtitles to the currently playing news broadcast and play it synchronously without affecting the currently playing content (for example, the news broadcast is currently being played, and the news broadcast is still playing normally at this time), for example, the heart disease precautions are played in the form of scrolling subtitles above the playing interface of the news broadcast, which does not affect the current playing content and also plays the content that the user wants to see.

[0053] Furthermore, when the controller pushes the playback content in the on-demand library to the smart display terminal for playback, the playback mode includes: the controller controls all smart display terminals in a target scene to play the pushed playback content at the same time or controls one or more smart display terminals specified in a target scene to play the pushed playback content; or the controller controls all smart display terminals in all target scenes to play the pushed playback content at the same time or controls one or more smart display terminals specified in all target scenes to play the pushed playback content. For example, Figure 3As shown, the controller controls all televisions (TV No. 1 and TV No. 2) in ward 501 to play the pushed content (such as dietary precautions after surgery) at the same time, or controls TV No. 1 corresponding to designated beds No. 1, No. 2 and No. 3 in ward 501 to play the pushed content (such as dietary precautions after surgery); the controller controls all TV No. 1, TV No. 2, TV No. 3 and TV No. 4 in wards 501, 502 and 503 to play the pushed content (such as dietary precautions after surgery) at the same time, or controls TV No. 1 in ward 501, TV No. 3 in ward 502 and TV No. 4 in ward 503 to play the pushed content (such as dietary precautions after surgery) at the same time.

[0054] Furthermore, the controller receives the push plan of the designated playback content sent by the upload display, and after the management server reviews and approves the push plan, pushes the push plan to the smart display terminal designated in the target scene. That is, the upload display is also used to formulate a push plan for education, and the push plan includes the designated playback corresponding target scene (for example, the designated playback corresponding ward), the designated playback time period (for example, 4:00-5:00 p.m.), and the number of loops (for example, 10 loops).

[0055] Furthermore, the controller can also record the on-demand records of all smart display terminals in all target scenes. For example, the controller records the on-demand records of televisions in all wards, so as to analyze the on-demand content watched by patients based on the on-demand records, so as to push the playback content in a targeted manner according to the patients' viewing habits, thereby achieving better education effects.

[0056] Furthermore, if Figure 5 As shown, the present invention also provides a controller accordingly, and the controller includes a processor 10, a memory 20 and a display 30. Figure 5 Only some of the components of the controller are shown, but it should be understood that implementation of all of the components shown is not required, and more or fewer components may be implemented instead.

[0057] The memory 20 may be an internal storage unit of the controller in some embodiments, such as a hard disk or memory of the controller. The memory 20 may also be an external storage device of the controller in other embodiments, such as a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), etc. equipped on the controller. Furthermore, the memory 20 may also include both an internal storage unit of the controller and an external storage device. The memory 20 is used to store application software and various types of data installed on the controller. The memory 20 may also be used to temporarily store data that has been output or is to be output. In one embodiment, an information push program 40 is stored on the memory 20, and the information push program 40 can be executed by the processor 10, thereby realizing the information push method in the present application.

[0058] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor or other data processing chip, used to run the program code or process data stored in the memory 20, such as executing the information push method.
