A method includes: interacting, by a first device, with a user through an application in a data collection range; after determining that the user is not located in the data collection range, determining, by the first device, that the user is located in a data collection range of a second device in a network; and sending, by the first device, to-be-migrated data to the second device, so that the second device continues to interact with the user based on the to-be-migrated data. The second device supports the application, the to-be-migrated data includes information about the application and progress information, and the progress information indicates progress of interaction between the first device and the user.

Inter-device data migration method and device

A method and an apparatus for controlling video output, where the method includes detecting in real time, by a security controller, whether an output resolution configured in a video display controller and a high-bandwidth digital content protection (HDCP) encryption status configured in a high-definition multimedia interface (HDMI) satisfy an HDCP requirement of a video, and when the HDCP requirement of the video is not satisfied, sending, by the security controller, an instruction to the video display controller instructing the video display controller to stop outputting the video. Hence, when the HDCP requirement of the video is not satisfied the output video is insecure such that the security controller sends the instruction to the video display controller instructing the video display controller to stop outputting the video. Therefore, security of the video output is ensured.
