KR-102963103-B1 - Screen projection method, receiving device and transmitting device

Abstract

The present application provides a screen projection method, a receiving device, and a transmitting device. The transmitting device actively searches for the receiving device via wireless scanning and establishes a wireless connection with the receiving device when the receiving device is scanned. Once the wireless connection is established, the receiving device automatically transmits a screen projection code to the already connected transmitting device, and the transmitting device presents the screen projection code to the user to perform a screen projection operation. In this process, the screen projection code is automatically acquired by the transmitting device and presented to the user to perform a screen projection operation in a timely manner, without the need for the user to perform cumbersome manual operations, thereby improving the timeliness of the screen projection operation.

Description

Screen projection method, receiving device and transmitting device The present application was filed with the Chinese Intellectual Property Office on February 26, 2020, and claims priority to the Chinese patent application with application number 202010120292.8 and invention title “Screen projection method, receiving end device and transmitting end device”, and all contents of the said Chinese patent application are incorporated into the present application by reference. The present application relates to the field of internet technology, and in particular to a screen projection method, a receiving device, and a transmitting device. With the advancement of internet technology, screen projection technology is being widely applied. Screen projection refers to transmitting media files from a transmitting device to a receiving device for display, and is also called multi-screen interactive. For example, by transmitting and broadcasting a video from a mobile phone to a smart TV, users can watch the video on the smart TV. In the current screen projection method, a screen projection code is placed on a receiving device, and the user obtains the screen projection code from the receiving device and inputs it into a transmitting device to select the start of screen projection. At this time, the transmitting device transmits a local media file to the receiving device, and the receiving device broadcasts and displays the media file. In actual applications, the screen projection code of the receiving device has a fixed validity period. After the validity period expires, the corresponding screen projection code becomes invalid, and it is necessary to refresh the screen projection code. The user obtains the refreshed screen projection code, inputs it, and selects the operation to start screen projection. As can be seen from this, since the above screen projection method requires cumbersome manual operations, the validity of the screen projection operation is reduced. The embodiments of the present application aim to provide a screen projection method, a receiving device, and a transmitting device, and to improve the timeability of screen projection operations. Specific technical solutions are as follows. In a first aspect, an embodiment of the present application provides a screen projection method applied to a receiving device, wherein the method is, A step of scanning a transmitting device using a preset wireless scanning technology; When a transmitting device is scanned, a step of establishing a wireless connection with the corresponding transmitting device; and It includes the step of obtaining a screen projection code, transmitting the screen projection code to an already connected transmitting device, and presenting the screen projection operation to be performed by displaying the screen projection code to the already connected transmitting device.
