Abstract

The invention provides a mobile terminal, a display device and a cross-network screen projection method, the mobile terminal establishes a cross-network communication connection with the display device through a communication unit, a proxy screen projection service is started, and the display device establishes a cross-network communication connection with the mobile terminal through a communicator; the proxy screen projection service obtains a screen projection instruction input by a user in a third-party application; the proxy screen projection service establishes a screen projection connection with the third-party application, and obtains screen projection information of the third-party application; the mobile terminal sends the screen projection information to the display device through the proxy screen projection service; the display device analyzes the screen projection information and presents a screen projection video; the cross-network screen projection of the third-party application based on the DLNA is realized through the screen projection connection of the proxy screen projection service of the mobile terminal and the third-party application based on the DLNA and the cross-network communication connection of the mobile terminal and the display equipment, so that the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of smart TVs, and in particular to a mobile terminal, a display device, and a screen projection method across networks. Background technique [0002] As a large-screen device, smart TV can provide better presentation for video playback and better viewing experience for users, so the video on the mobile terminal can be cast to the smart TV for playback. [0003] The main way to cast the video on the mobile terminal to the smart TV for playback is DLNA projection. DLNA projection is to push the video link of the video on the mobile terminal to the TV for playback, and the player on the TV obtains the audio and video from the network. DLNA screen projection requires the mobile terminal and the smart TV to be in the same local area network before it can be operated. [0004] With the needs of life, users have higher and higher requirements for cross-network projection. At present, the same manufacture...
