Abstract

The invention discloses display equipment and a screen projection method. The display equipment comprises a display; and a controller in communication connection with the display and configured to start an RTSP interaction thread in response to the received screen projection signal. Screen projection data sent by screen projection equipment is received, the screen projection data comprises a plurality of video frames, and the video frames comprise a plurality of RTP data packets; an RTP data packet is detected, and when the current RTP data packet is not continuous with the last received data packet, an RTSP message is sent to the screen projection equipment, so that the resolution of the screen projection equipment is reduced; and when the current RTP data packet is continuous with the last received RTP data packet, the display is controlled to play the screen projection data. The display device notifies the screen projection device to reduce the resolution of the screen projection data when playing is not smooth, so that the data volume is reduced, the display device achieves a smooth playing effect after receiving the low-resolution screen projection data, a user can smoothly watch the screen projection data, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device and a screen projection method. Background technique [0002] A display device is a TV product that can realize two-way human-computer interaction and integrate multiple functions such as audio-visual, entertainment, and data. In order to meet the diverse needs of users, the display device is equipped with various applications such as screen projection, audio-visual, entertainment, etc., and interacts and exchanges information with users through the user interface. [0003] For screencasting applications, Miracast screencasting is an important resource sharing method between display devices, which realizes media resource sharing through RTSP (Real TimeStreaming Protocol, real-time streaming protocol). For example, when using Miracast to cast a screen, the mobile phone needs to obtain the video frames of the media assets to be shared, then compress...
