Problems solved by technology

However, the content protection option is not a mandatory standard for RTSP. After some smartphones send the content protection option to the smart TV, the projection data sent to the smart TV is non-encrypted data, and the decryption of the non-encrypted data by the smart TV will fail. And then cause screencasting to fail

Abstract

Embodiments of the present application provide a display device and a screen projection method. The display device includes a display, a speaker, and a controller. The controller is configured to: start an RTSP interactive thread in response to receiving a screen projection signal; Before the screen projection data of the device, it is judged whether the HDCP authentication of the terminal equipment is successful; according to the success of the HDCP authentication of the terminal equipment, the RTSP interactive thread is controlled to enter the projection data interaction stage, and the RTSP interactive thread is controlled to start the encrypted stream thread to analyze the projection data, and the first Analyze the data; according to the HDCP authentication failure of the terminal device, control the RTSP interactive thread to enter the projection data interaction stage, and control the RTSP interactive thread to start the clearing thread to analyze the projection data and obtain the second analysis data; control the display and speakers to play the first analysis data or Content corresponding to the second parsing data. This application improves screen projection compatibility and screen projection success rate.

Description

technical field [0001] The present application relates to the technical field of display devices, and in particular, to a display device and a screen projection method. Background technique [0002] Smart TVs belong to large-screen display devices, and their audio-visual effects have obvious advantages over small-screen display devices such as smart phones. Sharing the display content on the smartphone to the smart TV often brings a better audio-visual experience to the user. An important way to share content between smart TVs and smartphones is Miracast. [0003] When both the smart TV and the smart phone have the Miracast screen projection function, media data sharing can be achieved through RTSP (Real Time Streaming Protoco, real-time streaming protocol). According to RTSP, the two ends of the device need to interact in multiple stages when performing screen projection. Among them, in the M3 stage, RTSP specifies some capability parameters that need to be negotiated bet...
