Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the following detailed description of specific embodiments of the present application is given with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present application are shown in the accompanying drawings. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Firstly, an applicable scene of the embodiment of the application is described, and the multi-screen display is a module which displays different contents from the first display screen on a second display screen connected with the android device and can control the content through keys or touch of the device. Taking a speakable game as an example, in the process of participating in the game by the player, the first display screen can be a main display screen for operation and watching by a background person; the rest display screens are slave display screens and are used for audience or player watching, and the second display screen can be used for displaying recitation texts; the third display screen may be used to display a situation picture of the current reciting text, for example, the reciting text is "Wang Lu mountain waterfall", and the third display screen is used to display a situation picture of a incense burner peak of a mountain corresponding to a verse, which may be a video or a picture.
Fig. 1 shows a flowchart of a multi-screen display method according to an embodiment of the present application, where the multi-screen display method according to the embodiment of the present application may be implemented by a multi-screen display device, and the multi-screen display device is integrated in a main display device and may be implemented by hardware and/or software. Referring to fig. 1, the method may specifically include:
s101, responding to the playing operation and generating a playing instruction.
Specifically, taking a recitation game scene as an example, a background staff member can operate the main display device, for example, when the game starts, the staff member clicks a start button on the main display device or touches a start icon on the main display device, so that the main display device responds to the play operation of the background staff member to generate a play instruction.
S102, encoding the display data to be split into codes according to a set protocol, wherein the set protocol comprises the matching relation between the display data to be split and the device identifiers of the slave display devices.
Optionally, after the master display device generates the play command, a preloading step may be started in a countdown buffering process, that is, a step of transmitting the display data to be split into the slave display devices for display. Wherein the display data to be split-screen comprises display content to be split-screen and display configuration data, the display content to be split-screen can comprise texts, videos and the like, for example, the text is a poem text of "Wang Lu mountain waterfall", and the video is a situation picture of a Lu mountain censer peak corresponding to each poem. And display configuration data is used to configure the current display page, wherein the display configuration data includes, for example, font color, font size, background color, display brightness, and the like.
Specifically, the display data to be split-screen is encoded according to a set protocol, where the set protocol may include a matching relationship between the display data to be split-screen and the device identifier of each slave display device, that is, in the encoding operation, each group of display data to be split-screen corresponds to the device identifier of the slave display device to be displayed, and in a specific example, the device identifier may be a MAC (MEDIA ACCESS Control Address) of the slave display device, or may be an ID (Identity document, identity number) of the slave display device. A device identifier may uniquely identify a slave display device such that each slave display device receives its own data to be split-screen display based on its own device identifier.
S103, sending the coded display data to be split screen to the corresponding slave display equipment according to the set protocol.
The data format of the encoded data to be split-screen displayed is processed according to a set protocol, for example, the data format includes a device identification field of the slave display device, a content field to be split-screen displayed and a check data field. And the slave display device to which each set of split-screen display data is to be transmitted can be determined by the device identification. Therefore, according to the set protocol, the coded data to be split-screen display are sent to the corresponding slave display devices, and each slave display device receives the data to be displayed corresponding to the slave display device.
In a specific example, the verification data is used for indicating each slave display device to verify the accuracy and the integrity of the received display content to be split-screen, so as to indicate each slave display device to generate a response instruction after the verification is successful. For example, the check method may be CRC (Cyclic Redundancy Check ).
S104, if the response instructions from all the slave display devices are received, sending a playing instruction to each slave display device to instruct each slave display device to play according to the display data to be split; and each response instruction is generated after each slave display device receives the display data to be split screen corresponding to the device identifier.
Specifically, each slave display device generates a response instruction after receiving the display data to be split corresponding to the self device identifier and after verification is successful, the response instruction is sent to the master display device, after the master display device receives the response instructions of all the slave display devices, a play instruction is sent to each slave display device, and then each slave display device plays according to the display data to be split. In a specific example, speakable text is played from display device 1 and the corresponding contextual picture is played from display device 2.
In the embodiment of the application, the playing instruction is generated by responding to the playing operation, so that the data to be split-screen display is encoded according to the set protocol comprising the matching relation of the split-screen display data and the equipment identification of each slave display equipment, and the encoded data to be split-screen display is sent to the corresponding slave display equipment according to the set protocol, so that each slave display equipment can receive the data to be split-screen display in a targeted manner, and compared with an external display card, the stability of data transmission is improved; in addition, if the master display device receives the response instructions from all the slave display devices, the master display device sends the playing instructions to all the slave display devices so as to instruct all the slave display devices to play according to the display data to be split. The limitation of the space distance between the main display device and each auxiliary display device is broken through, and multi-screen different display is realized.
Based on the technical scheme, the technical scheme of the application further comprises the following steps: updating the time tag of the current playing progress according to the set time period; and sending the time label of the playing progress to each slave display device to instruct each slave display device to update the playing progress according to the time label of the playing progress.
Specifically, during the playing process, there may be a situation of playing stuck due to network communication or the like. Because the main display device is used as the main control device controlled and used by the background workers, the main display device monitors the progress in the reading process, and updates the time label of the current playing progress according to the set time period, for example, the time label of the current playing progress is 10s in the reading process of 'Rebiekang bridge', and the set time period is 20ms. After the time labels of the playing progress are sent to each slave display device, each slave display device detects whether the difference between the time labels of the current playing progress and the actual time of the current playing progress of the slave display device is larger than a set time difference threshold value, if yes, the corresponding slave display device plays according to the time labels of the current playing progress to update the playing position, otherwise, the slave display device continues playing according to the current playing progress so as to ensure the synchronization of the display content. By way of example, the set time difference threshold may be 8ms.
Exemplary, after sending the encoded display data to be split screen to the corresponding slave display device, the method further includes: if the response instructions of all the slave display devices are not received within the preset time, the slave display device which does not receive the response instructions is determined to be the target slave display device; recoding the display data to be split of each target slave display device according to a set protocol and then sending the recoded display data to the corresponding target slave display device so as to instruct each target slave display device to generate a response instruction; until all the response instructions from the display device are received.
If the master display device does not receive the response instructions of all the slave display devices within the preset time, the master display device indicates that the display data to be split-screen of part of the slave display devices may fail to be received or the response instructions are failed to be sent, and at this time, the slave display device which does not receive the response instructions by the master display device is determined to be the target display device. For example, if the master display device does not receive a response instruction from the slave display device 3, the slave display device 3 is determined as the target slave display device. And the target slave display equipment receives and checks the target slave display equipment again, generates a response instruction after the check is successful, and sends the response instruction to the master display equipment. This step is performed as long as the master display device does not receive the response instructions of all the slave display devices, until the master display device receives the response instructions of all the slave display devices.
In addition, in order to prompt a background staff, if the response instructions of all the slave display devices are not received within the preset time, the loading error prompt information is displayed. So that the background staff can perform corresponding operation treatment in time.
Fig. 2 is a flowchart of a multi-screen display method according to an embodiment of the present application, where the multi-screen display method according to the embodiment of the present application may be implemented by a multi-screen display device, and the multi-screen display device is integrated in a slave display device and may be implemented by hardware and/or software. Referring to fig. 2, the method may specifically include:
S201, analyzing the display data to be split screen obtained after the main display equipment is encoded according to a set protocol, wherein the set protocol comprises the matching relation between the display data to be split screen and the equipment identification of each auxiliary display equipment.
Specifically, since the setting protocol includes the matching relationship between the display data to be split and the device identifier of each slave display device, each slave device can determine which display data to be split belongs to the slave display device according to the display data to be split, and only receive the display data to be split, which is needed to be received by the slave display device, and temporarily store the received display data to be split in the storage unit.

S204, receiving a play instruction of the main display device, and playing according to the display data to be split; the playing instruction is sent to each slave display device after the master display device receives response instructions from all the slave display devices.
Specifically, after receiving the response instructions from all the slave display devices, the master display device sends the playing quality to each slave display device, each slave display device receives the playing instruction of the master display device and then plays according to the display data to be split,
In the embodiment of the application, the slave display equipment analyzes the display data to be split obtained by encoding the master display equipment according to the set protocol comprising the matching relation between the display data to be split and the equipment identifiers of the slave display equipment, and receives the display data to be split matched with the current slave display equipment, thereby realizing targeted data reception and improving the stability of data transmission compared with an external display card; the slave display equipment sends a response instruction to the master display equipment, receives a play instruction sent by the master display equipment after receiving the response instructions from all the slave display equipment, and plays according to the display data to be split.

Based on the technical scheme, the technical scheme of the embodiment of the application further comprises the following steps: receiving a time tag of the current playing progress from the main display device; if the difference between the time label of the current playing progress and the actual time of the current playing progress of the self slave display device is larger than a set time difference threshold value, playing according to the time label of the current playing progress.
Specifically, each slave display device receives the time tag of the current playing progress from the master display device, judges the difference between the time tag of the current playing progress and the time of the current playing progress of the slave display device, and if the difference is larger than a set time difference threshold, the synchronization is influenced, the phenomenon of blocking and the like is caused, the visual perception of a user is influenced, at the moment, the slave display device updates the playing position, plays according to the time tag of the current playing progress, and ensures the synchronization of the display content.
