Abstract: A projection method and system to control at least two of the following: projection content, a projection device, and projection time. The projection method includes: obtaining a projection condition that includes at least two of the following: a projection content condition, a projection device condition, and a projection time condition; receiving a projection instruction used to request to project, to a destination electronic device, multimedia content currently displayed by a source electronic device. The projection instruction includes projection information and if the projection information satisfies the projection condition, the projection method performs projection playback based on a uniform resource locator of the projection content in the projection information.

Abstract: In an embodiment a screen projection method includes determining, by a project end, to-be-projected data when a screen projection function is enabled, obtaining, by the project end, first data permission of the project end for the to-be-projected data and second data permission of a receive end for the to-be-projected data when the to-be-projected data is media data and projecting, by the project end, the to-be-projected data onto the receive end in a screen mirroring manner when the first data permission is higher than the second data permission or projecting, by the project end, the to-be-projected data onto the receive end in a digital living network alliance manner when the first data permission is lower than the second data permission.

Abstract: A packet sending method includes, when a network element in a serial network receives a to-be-forwarded packet at a previous node from a previous network element, and when the network element needs to send a to-be-sent packet at a current node, determining whether the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, where the network element is an intermediate network element in the serial network; when the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, superimposing the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node, to obtain a to-be-forwarded packet at the current node; and sending the to-be-forwarded packet at the current node to a next network element of the network element.

Abstract: Some embodiments include a first electronic device that automatically sends a first search request and a second search request. The first search request is used in a search for an electronic device having a first projection receiving capability related to a first projection protocol, and the second search request is used in a search for an electronic device having a second projection receiving capability related to a second projection protocol. In some embodiments the first electronic device receives a first feedback message or a second feedback message, or any combination thereof, from a second electronic device, and the first electronic device automatically displays, in response to the first feedback message, the second feedback message, the first identity related to the second electronic device.

Abstract: A display picture synchronization method includes a source device that sends a first picture frame and a first specified display time corresponding to the first picture frame to each of the sink devices. If each of the sink devices successfully receives the first picture frame and determines that the first picture frame is capable of being displayed based on the first specified display time, each of the devices for performing picture frame synchronization display displays the first picture frame based on the first specified display time. Each of the devices for performing picture frame synchronization display does not display the first picture frame if a first sink device in the sink devices fails to receive the first picture frame or successfully receives the first picture frame but determines that the first picture frame is incapable of being displayed based on the first specified display time.
