Conference tablet: the intelligent conference flat plate integrates a plurality of conference office equipment such as a projector, an electronic whiteboard, a curtain, a sound box, a television, a computer and the like.
In the use of conference systems, conference boards are often used to present conference content as a versatile, convenient to use device. When the conference content is displayed, the conference content is in communication connection with equipment for sending audio and video signals through a High-Definition Multimedia Interface multimedia interface (HDMI for short) on a conference flat plate. For example, a user transmits desktop video of a personal computer (Personal Computer, abbreviated as PC) to a conference tablet terminal in real time through the HDMI interface, and the conference tablet terminal performs sharing of the interface of the PC terminal. In addition, the conference flat plate can also send the received desktop video of the PC side to a plurality of clients through video conference software, and the clients can also share the screen of the PC side together. However, when the audio and video signals of the PC end are accessed and displayed through the HDMI interface, if the audio and video signals are accessed to the conference panel through the HDMI interface, the conference panel will process and display the newly accessed audio and video signals, and meanwhile, the processing process of the original accessed audio and video signals is cut off. For example, if a new PC terminal inputs an audio/video signal through an HDMI interface on a conference board while an audio/video preview of the PC terminal is being performed, the progress of the audio/video preview of the PC terminal is cut off, the new PC terminal will be displayed on the display of the conference board, and from the time when a conference person can preview only the new PC terminal audio/video signal on the conference board, the conference board cannot preview the new PC terminal audio/video signal. Thus, the problem of inconvenience in previewing when meeting personnel watch the shared screen of the PC side through the conference flat plate is caused, and the problem of complex operation when meeting personnel share the screen of the PC side through the conference flat plate is also caused.
Based on this, the application provides a display device and an interface display method thereof, wherein an OPS micro module is added in an existing conference panel, an operating system corresponding to the OPS micro module is correspondingly led in the conference panel, and an HDMI interface, an HDMI switch, a control pin on a processor and the like related to the operating system are added. When two paths of audio and video signals are sequentially or simultaneously input into the conference flat plate, the OPS micro-module is used for respectively processing the two paths of audio and video signals and then the operating system is used for carrying out the same-screen display of the two paths of audio and video signals. At this time, both paths of audio and video signals can be displayed, and the problem of processing processes of the audio and video signals accessed before the newly accessed audio and video signals are cut off can be avoided. Therefore, conference staff can watch the screen sharing of a plurality of PC ends through the conference flat plate, and the conference staff only needs to access audio and video signals into the conference flat plate when carrying out the screen sharing of the PC ends through the conference flat plate, so that the operation is simple and convenient.
