Abstract: An electronic device establishes a connection to an audio device, the electronic device displays a first image, the audio device outputs audio data synchronized with the first image, the electronic device receives a projection operation, and the electronic device sends projection information of the first image to a display device based on the projection operation. The display device displays the first image based on the projection information, and the audio device outputs the audio data synchronized with the first image.

Abstract: Embodiments of this application provide a picture transmission method and apparatus. A photographer inputs an operation instruction in a user interface of a first electronic device, to select a first picture whose imaging effect needs to be shared. The first electronic device processes the first picture based on specification information of a display of a second electronic device, to obtain each second picture and a posing score that are used to represent the imaging effect of the first picture. Then, the first electronic device sends each second picture and the posing score to the second electronic device, so that a user wearing the second electronic device can view the imaging effect of the first picture, and a photographed object does not need to move back and forth to the photographer to view a photographing effect.

Abstract: Systems, methods and computer-readable storage media for profiling software and providing migration effort estimations are described. A software profiling system may be configured to receive code for an application that executes in a first computing environment and analyze the code to determine efforts associated with migrating the application to execute in one or more second computing environments. For instance, the software profiling system may be configured to determine the migration efforts for migrating a software application that operates in a non-cloud computing environment to a cloud computing environment. The software profiling system may generate transformation points that serve as estimation units for solving anomalies identified to bring various aspects of the application into conformance with one or more of the second computing environments.
