Continuing with
For example, the third HDMI 1013 and the fourth HDMI 1014 can be used to access data collected by a local terminal such as a laptop computer, a desktop computer, a camera and other video and audio device of a teacher, which, after being processed by the processing control module 102, is sent to the first HDMI 1011, the second HDMI 1012, etc. so as to be sent to an on-site multimedia display device and/or a remote display device for display.
In one example, the multimedia module 101 comprises one set of network input interfaces configured to connect to a cloud server for uploading a live streaming/recorded courseware to the cloud server for storage. In conjunction with
The RJ45 switch module 1015 of the embodiment of the present application supports Power Over Ethernet (POE), and can access an Ethernet device, such as a webcam, a POE camera, a switch, and the like via the RJ45 switch module 1015. The RJ45 switch module 1015 may also be used for local area network (LAN) isolation, isolated from the network of RJ45 to facilitate device management.
In another example of the present application, the cloud server may also be requested to retrieve a pre-stored recorded video file and then send the recorded video file to an on-site multimedia display device and/or a remote display device, for display.
In yet another example, the multimedia module 101 comprises at least two sets of webcam interfaces for acquiring an instructor's lecturing image/video signal and an image/video signal of on-site students, respectively captured by local webcams. The RJ45 switch module 1015 of the embodiment of the present application can be used as an unidirectional input interface and is provided with 2 POE cameras to collect video data. In a further example, four POE cameras may be provided, wherein two POE cameras are used to collect video data, and the other two POE cameras are reserved for expansion according to different usage scenarios.
In another further example, the multimedia module 101 comprises two sets of multimedia output interfaces; wherein one set of multimedia output interfaces is configured to connect to a head-up display arranged locally, and the other set of multimedia output interfaces is configured to connect to a big screen arranged locally.
In conjunction with
For example, the first HDMI 1011 connects to a big screen, projector or the like, and the second HDMI 1012 connects to a head-up display.
In an embodiment of the present application, the multimedia module further comprises an audio receiving module 1016 configured to receive and store an instructor's audio signal. For example, the audio receiving module includes a USB interface and connects to a microphone via the USB interface to collect the audio signal of an instructor.
In another embodiment of the present application, the multimedia module further comprises an audio output module 1017 configured to output system and remote audio signals. For example, the audio output module includes a USB interface and connects to a speaker via the USB interface to play the system and remote audio signals on site.
In one embodiment of the present application, the first multimedia signal to be collected both on-site and from remote can be collected through devices such as desktop computer, laptop computer, video camera, webcam, and wireless co-screener. For example, these devices are connected to the HDMIs of the apparatus, to transmit the first multimedia signal collected both on-site and from remote to the apparatus.
In a smart classroom application scenario, the multimedia capture device may be a camera and a laptop computer, wherein the camera captures the video image and the audio signal of a teacher, and the laptop computer captures the video signal of a shared file displayed on a desktop of the laptop computer. The camera is connected to the multimedia module via the first HDMI 1011, and the laptop computer is connected to the multimedia module via the second HDMI 1012, thereby forming two first multimedia signals.
Wherein, the processing control module 102 is configured to receive and process the first multimedia signals to obtain second multimedia signals, and send the processed second multimedia signals to the multimedia module 101.
In another embodiment of the present application, the multimedia module further comprises at least one set of multimedia output interfaces configured to connect to, and transmit the processed second multimedia signal received from the processing control module to, a multimedia display device arranged locally and/or remotely for display.
For example, the multimedia module 101 collects three multimedia signals altogether, the first multimedia signal is a video signal collected by a webcam; the second multimedia signal is a video signal collected by an HDMI interface (for example, a laptop computer is connected by an HDMI to obtain a file displayed thereon); and the third multimedia signal is an audio signal collected by a microphone. Wherein, two video signals can be output to the home screen as the video signal of the home screen, or output to the head-up display as the video signal of the head-up display, or output to the remote display device; while the audio signal is played through the speaker.
In embodiments of the present application, it is also possible to collect through a webcam, and display on a local display terminal (such as a home screen), the image of a remote student.
In a smart classroom application scenario, the multimedia capture device may be a webcam and a laptop computer, where the webcam is connected to the multimedia module via the first HDMI 1011, and the laptop computer is connected to the multimedia module via the second HDMI 1012. The webcam captures the video image on a laptop computer of a teacher, or the laptop computer captures the signal of a shared file displayed on the desktop of the laptop computer, thereby forming two first multimedia signals, which are the original multimedia signals collected by the multimedia capture device and cannot be directly displayed on the display device. The processing control module 102 processes the two first multimedia signals to form two second multimedia signals, which would be multimedia signals that can be directly displayed on a display device. For example, the processing control module 102 carries out synchronous processing of video signal and audio signal; for another example, the processing control module 102 performs format conversion processing on the first multimedia signal, and the like.
The processing control module 102 of the embodiment of the present application may comprise a central processing unit (CPU), a graphic processing unit (GPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other forms of processing units with data processing capabilities and/or instruction execution capabilities, and may be other component in the apparatus 100 for implementing in-person teaching and online teaching to perform the desired functions.
