An electronic device is communicatively connected to a peripheral device, and a virtual display apparatus and a virtual UAC device are virtualized on the electronic device. The virtual UAC device is configured to establish an audio data channel between the electronic device and the peripheral device, to obtain audio data. Image data is obtained from an output interface of a graphics card of the electronic device. If the image data needs to be transmitted to the virtual display apparatus, the image data, or the image data and the audio data are transmitted to the peripheral device, and are transmitted to the outside by the peripheral device. The present disclosure can not only implement compatibility of cross-platform operating systems, but also support different display modes such as duplication and extension."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secondary-stream data transmission method and display method for use in conference, conference system, and peripheral device","description":"The present disclosure provides a secondary-stream data transmission method for use in a conference.
