Problems solved by technology
During the research process, the applicant found that, limited by the hardware configuration and model of the display device, many display devices do not have cameras and microphones at present, so that the display device cannot collect and upload the audio and video data of the local user to the server. It is also impossible to obtain the audio and video data of the local user from the server. When the video call is started, the local user can see the video screen of the friend and hear the voice of the friend, but the friend cannot see the video screen of the local user and cannot hear the voice of the friend. The voice of the local user is heard, making it impossible for the two parties in the call to carry out effective chat interaction

The invention discloses a screen projection method for a video call, a display device and a terminal device. After the video call is started, the collected audio and video data of the local user is uploaded to the server; in response to the click operation on the screen projection control, the display Device list; in response to the selection operation of the target device in the device list, send a screen projection request to the target device; in response to the screen projection success information sent by the display device, stop receiving the audio and video data of each call object from the server, and only display the current The video screen of the end user; the successful screen projection information is that the target device responds to the screen projection request, accesses the virtual room according to the call ID, receives the audio and video data of each call object from the server according to the device ID, and displays the video image of each call object sent. In this application, the terminal is used as the audio and video collection device of the display device, and the video call of the terminal is projected to the display device for playback, so that the display device is no longer limited by its own configuration when making a video call.
Description
Technical field [0001] The present invention relates to the field of display device, and more particularly to a screening method of a video call, a display device and a terminal device. Background technique [0002] Video call applications can be installed in the TV and other display devices. After the video call is launched, the local user will join the virtual room and chat with friends in the virtual room. Applicants have found in the research process, which is limited to the hardware configuration and model of display devices. Many display devices do not have camera and microphones, making display devices unable to collect and signal audio and video data for this user on the server. You can't get the audio and video data of your local user from the server. When you start the video call, this user can see the video picture of your friend and listen to the voice of your friends, but the friend can't see the video screen of this user and cannot listen. Go to the sound of the loc...
