- Step 2 1 The target device sends a request message to the network server to request synchronization control operation on the target device and the source device by using the target device.
- Step 2 After receiving the request message, the network server determines whether the target device and the source device are in the same group, whether the source device is online, and the target device and the source device currently play. Whether the media content is the same.
- Step 2 1 5 when the network server determines that the target device and the source device are in the same group, the source device is online, and the target device and the source device currently play the same media content, the network The server sends a feedback message corresponding to the request message to the target device, to notify the target device to perform a synchronization control operation on the target device and the source device.
- Step 2 After the target device confirms that the synchronization control operation is performed, the network server sets the target device and the source device to a connected state.
- Step 2 The target device performs a synchronous control operation on the target device and the source device to synchronize the state of the media content of the target device and the source device.
- the synchronization control operation includes: media content suspension, media content fallback, media content fast forward, and media content closed. For example, if the target device fast forwards the media content played by the target device, the media content played on the source device is also fast forwarded, but is not limited thereto.
- Step 2 The network server monitors the playing progress of the media content in the source device, and after the source device is offline, saves the playing progress of the media content in the source device.
- Step 2 1 When the media content is played by the target device in the same group as the source device, the network server prompts the playback progress of the media content of the target device on the source device.
- Step 2 2 0 After the target device determines that the media content is played according to the playback progress of the source device, the target device plays the media content.
- the method for multi-screen interaction, the source device and the target device exchange the respective device parameters, and when the target device needs to perform multi-screen interaction, the source device will play the media content that the source device is playing.
- the media information is sent to the target device, so that the target device requests the media content from the network server according to the media information and the device parameter of the target device; the network server sends the media content according to the device parameter of the target device.
- the target device sends the media content corresponding to the device parameter of the target device; and the target device queries the play status of the media content that the source device is playing according to the device parameter of the source device, and plays according to the The status plays the media content of the target device.
- the source device and the target device in the embodiment of the present invention avoid multi-screen interaction and also need to rely on the STB or the home media server, and can be different according to device parameters of different terminals through the network server.
