Embodiment 2

[0137] image 3 It is a flow chart of a courseware annotation method provided by Embodiment 2 of the present invention. This embodiment is based on the foregoing embodiments, and further increases the processing operation of superimposing annotation information on external video data. The method specifically includes the following steps:

[0138] S301. The main display controller receives an external video signal transmitted by the electronic device, and the external video signal is used to display courseware.

[0139] S302. The main display controller receives an annotation operation.

[0140] In the specific implementation, the annotation operation is an annotation. The so-called annotation can refer to criticizing and annotating in the courseware while reading, and its function is to help users grasp the content of the courseware.

[0141] When the annotation operation is triggered, the user can select the attribute of the annotation information, for example, the color of ...

Abstract

The embodiment of the invention discloses a courseware annotation method, system and device and a storage medium. The courseware annotation method comprises the steps that a main display controller receives an external video signal transmitted by an electronic device; the main display controller receives the annotation operation and generates annotation information on the external video signal; the main display controller converts the external video signal with the annotation information to obtain a first sub-video signal matched with the main screen; the main display controller transmits thefirst sub-video signal to the signal converter; the video converter is also used for converting the first sub-video signal into an external video signal and transmitting the external video signal to the signal switcher; the main display controller transmits the first enable signal to the signal switcher so as to control the signal switcher to transmit an external video signal to the auxiliary display controller, and the auxiliary display controller is used for converting the external video signal into a first branch video signal and transmitting the first branch video signal to the auxiliary screen for playing. The main display device and the auxiliary display device can synchronously add comments to courseware, and the flexibility is high.

Description

technical field [0001] The embodiments of the present invention relate to educational technologies, and in particular to a method, system, device and storage medium for annotating courseware. Background technique [0002] In some classrooms, a machine is used as a multimedia device combined with a blackboard for teaching. [0003] However, the screen size of one machine is limited. In the case where a larger screen is required to display teaching content, some classrooms use two machines placed side by side to extend the display area. [0004] The two machines are only physically spliced ​​together, and the two machines still work independently, independently display the courseware, and independently annotate the courseware. When connecting to other courseware, the two machines need to be independently connected to different electronic devices. The equipment provides courseware, so it is necessary to annotate the courseware in different machines, and the operation is compli...
