Devices, methods, and non-transitory program storage devices are disclosed to enable the automatic establishment of a secure audio/video data streaming connection between electronic devices. For example, a first electronic device may enter into a first state of a peer device advertising protocol, and then, based on a determination that the first electronic device meets a first set of device state criteria (e.g., including at least an orientation state criterion), the first electronic device may enter into a second (e.g., enhanced) state of the peer device advertising protocol. In response to detecting a presence of a second electronic device in its proximity, the first electronic device may connect to the second electronic device via a secure peer-to-peer connection protocol and then send one or more images captured by a first image capture device of the first electronic device to the connected second electronic device via the secure wireless peer-to-peer connection protocol.

Framework for automatically establishing secure connections for streaming audio and video data between devices based on device state criteria

In an example method, a system receives a plurality of frames of a video, and generates a data structure representing the video and representing a plurality of temporal layers. Generating the data structure includes: (i) determining a plurality of quality levels for presenting the video, where each of the quality levels corresponds to a different respective sampling period for sampling the frames of the video, (ii) assigning, based on the sampling periods, each of the frames to a respective one of the temporal layers of the data structure, and (iii) indicating, in the data structure, one or more relationships between (a) at least one the frames assigned to at least one of the temporal layers of the data structure, and (b) at least another one of the frames assigned to at least another one of the temporal layers of the data structure. Further, the system outputs the data structure.
