Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail 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 of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. A process may be terminated when its operations are completed, but may have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.
Firstly, an applicable scene of the embodiment of the application is explained, in the multi-screen display, different contents from a first display screen are displayed on a second display screen connected with an android device, and a module in the second display screen can be controlled through a key or a touch of the device. Taking a reading game as an example, in the process of contestants, the first display screen can be a main display screen for background personnel to operate and watch; the other display screens are secondary display screens for the audience or players to watch, and the second display screen can be used for displaying recited texts; the third display screen may be configured to display a situation picture of the current reciting text, for example, the reciting text is "hope cottage mountain waterfall", and the third display screen is configured to display a situation picture of the incense burner peak of cottage mountain corresponding to the verse, which may be a video or a picture.
Fig. 1 is a flowchart illustrating a multi-screen different display method according to an embodiment of the present disclosure, where the multi-screen different display method according to the present disclosure can be executed by a multi-screen different display device, and the multi-screen different display device is integrated with a main display device and can be implemented in a hardware and/or software manner. Referring to fig. 1, the method may specifically include:
s101, responding to the playing operation and generating a playing instruction.
Specifically, for example, when reciting the scene of the game, the background staff may operate the main display device, for example, when the game starts, the staff 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 generates a play instruction in response to the play operation of the background staff.
S102, encoding the data to be split-screen displayed according to a set protocol, wherein the set protocol comprises the matching relation between the data to be split-screen displayed and the equipment identification of each slave display equipment.
Optionally, after the master display device generates the play instruction, in the buffering process of the countdown, the preloading step may be started, that is, the step of transmitting the to-be-split-screen display data to each slave display device for display. The data to be displayed in the split screen includes content to be displayed in the split screen and display configuration data, the content to be displayed in the split screen may include text, video and the like, for example, the text is a poetry sentence text of "hope cottage mountain waterfall", and the video is a situation picture of the cottage mountain incense burner peak corresponding to each sentence poetry. And the display configuration data is used for configuring 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 data to be displayed in a split screen is encoded according to a set protocol, where the set protocol may include a matching relationship between the data to be displayed in a split screen and device identifiers of each slave display device, that is, each set of data to be displayed in a split screen corresponds to a device identifier of the slave display device to be displayed in an encoding operation, and in a specific example, the device identifier may be a Media Access Control (MAC) Address of the slave display device or an Identity Document (ID) of the slave display device. One device identification can uniquely determine one slave display device, so that each slave display device receives the data to be split-screen display which belongs to the slave display device according to the own device identification.
And S103, sending the coded data to be displayed in a split screen mode to corresponding slave display equipment according to a set protocol.
The data format of the encoded data to be displayed in a split screen mode 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 displayed in a split screen mode and a check data field. And the slave display device to be sent for each group of split-screen display data can be determined through the device identification. Therefore, according to the set protocol, the coded data to be displayed in a split screen mode is sent to the corresponding slave display devices, and each slave display device receives the data to be displayed corresponding to the own device.
In a specific example, the verification data is used for instructing each slave display device to verify the accuracy and integrity of the received content to be split-screen displayed, so as to instruct 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 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 to-be-split-screen display data; and each response instruction is generated after each slave display device receives the to-be-split-screen display data corresponding to the own device identification.
Specifically, each slave display device generates a response instruction after receiving the to-be-split-screen display data corresponding to the device identifier of the slave display device and after the verification succeeds, the response instruction is sent to the master display device, when the master display device receives the response instructions of all the slave display devices, the play instruction is sent to each slave display device, and then each slave display device plays according to the to-be-split-screen display data. In a specific example, speakable text is played from display device 1 and a corresponding context screen is played from display device 2.
In the embodiment of the application, a play instruction is generated by responding to a play operation, the data to be subjected to split screen display is encoded according to a set protocol comprising the matching relationship between the split screen display data and the equipment identifier of each slave display equipment, and the encoded data to be subjected to split screen display is sent to the corresponding slave display equipment according to the set protocol, so that the data to be subjected to split screen display by each slave display equipment is received in a targeted manner, and compared with an external display card, the stability of data transmission is improved; in addition, if the main display device receives response instructions from all the slave display devices, the main display device sends a playing instruction to each slave display device so as to instruct each slave display device to play according to the to-be-split-screen display data. The limitation of the space distance between the main display equipment and each auxiliary display equipment is broken through, and multi-screen different display is realized.
On the basis of the above technical solution, the technical solution of the present application further includes: updating the time label of the current playing progress according to a set time period; and sending the time label of the playing progress to each slave display device to indicate 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 that the playing is stuck due to network communication and the like. The main display device is used as a main control device controlled and used by a backstage worker, so that the main display device monitors the progress in the reading process, and updates the time label of the current playing progress according to a set time period, for example, in the process of reading Redo-Ou-kang-bridge, the time label of the current playing progress is 10s, and the set time period is 20 ms. And after the time label of the playing progress is sent to each slave display device, each slave display device detects whether the difference between the time label of the current playing progress and the actual time of the current playing progress of the slave display device is greater than a set time difference threshold value, if so, the corresponding slave display device plays according to the time label of the current playing progress to update the playing position, otherwise, the slave display device continues to play according to the current playing progress of the slave display device to ensure the synchronization of the display contents. Illustratively, the set time difference threshold may be 8 ms.
Exemplarily, after the encoded data to be displayed in a split screen mode is sent 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, determining the slave display devices which do not receive the response instructions as target slave display devices; recoding the to-be-split-screen display data of each target slave display device according to a set protocol and then sending the recoded data to the corresponding target slave display device so as to indicate each target slave display device to generate a response instruction; until all the response instructions of the slave display devices are received.
If the main display device does not receive the response instructions of all the slave display devices within the preset time, the main display device indicates that the receiving of the data to be split-screen displayed of part of the slave display devices may fail or the sending of the response instructions fails, and at this time, the slave display device which does not receive the response instructions of the main display device is determined as the target display device. For example, if the master display apparatus does not receive the response instruction of the slave display apparatus 3, the slave display apparatus 3 is determined as the target slave display apparatus. And the data to be split-screen displayed of the target slave display equipment is reproduced and encoded according to the set protocol again and is sent to the corresponding target slave display equipment, so that the target slave display equipment receives and verifies again, a response instruction is generated after the verification is successful, and the response instruction is sent to the master display equipment. This step is performed as long as the master display device does not receive the reply instructions of all the slave display devices until the master display device receives the reply instructions of all the slave display devices.
In addition, in order to prompt background staff, if all response instructions of the slave display equipment are not received within the preset time, loading error prompt information is displayed. So that the background staff can carry out corresponding operation treatment in time.
