Television screen projection method and device, cloud server and terminal equipment

Abstract

The embodiment of the invention relates to a television screen projection method and device, a cloud server and terminal equipment. The method comprises the following steps: receiving first identity information and a secret key which are sent by the terminal equipment and correspond to the terminal equipment, a screen projection code acquired in advance and second identity information corresponding to screen projection equipment; and verifying the first identity information, the secret key, the screen projection code and the second identity information; if the verification is successful, generating a token used for screen projection according to the first identity information and the second identity information; sending the token to the terminal equipment; and receiving a screen projectioncommand sent by the server; and when it is determined that the token is valid, sending the screen projection command to the screen projection device. A bridge between screen projection device and theterminal equipment is erected through the cloud server, and network communication between the screen projection device and the terminal equipment is achieved. Even if AP network isolation exists in some application scenes, the television screen projection effect can be completely achieved. The network signal is not weakened, and the video playing state is at the playing level under the normal network condition, so that the user experience is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for projecting a TV screen, a cloud server, and a terminal device. Background technique [0002] With the continuous development of science and technology, the performance of electronic equipment is more and more widely used. For many home users nowadays, TV projection is already a common thing. For scenarios where APs are isolated in network environments such as hotels, it is difficult to implement TV projection. Regardless of the level of the environment, although the standard equipment in the room also includes a TV, because most of the indoor WiFi is isolated from the AP, it is impossible to establish a communication connection between the hardware that performs the TV projection function and the smart terminal, and thus cannot pass this There are many ways to realize TV projection. [0003] Although, it is also possible to ...
