Abstract
A communication protocol switching method includes that a first device communicates with a second device using a first protocol to project a screen of the first device to the second device; and when a first application in the first device is opened or a media file stored in the first device is opened, the first device switches to a second protocol to communicate with the second device and to project a display user interface of the first application or the media file to the second device, where the first application manages or plays at least one media file.
Claims20
A method implemented by a first device, wherein the method comprises:
- communicating, using a first protocol, with a second device to project a screen of the first device to the second device;
- detecting that a first application in the first device is opened or a first media file stored in the first device is opened, wherein the first application manages or plays at least one second media file;
- and
- switching, in response to detecting that the first application is opened or the first media file is opened, to a second protocol to project a display user interface of the first application or the first media file to the second device.
A first device comprising:
- a screen;
- a memory configured to store instructions;
- and
- at least one processor in communication with the memory and coupled to the screen, wherein the instructions cause the at least one processor to be configured to:
- communicate, using a first protocol, with a second device to project the screen to the second device;
- detect that a first application in the first device is opened or a first media file stored in the first device is opened, wherein the first application manages or plays at least one second media file;
- and
- switch, in response to detecting that the first application is opened or the first media file is opened, to a second protocol to project a display user interface of the first application or the first media file to the second device.
A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable storage medium and that, when executed by a processor, cause a first device to:
- communicate, using a first protocol, with a second device to project a screen of the first device to the second device;
- detect that a first application in the first device is opened or a first media file stored in the first device is opened, wherein the first application manages or plays at least one second media file;
- and
- switch, in response to detecting that the first application is opened or the first media file is opened, to a second protocol to project a display user interface of the first application or the first media file to the second device.
