    Abstract: This application is directed to a camera system having one or more processors, memory having a limited capacity, a camera element and a microphone. The camera system captures video and audio data in real-time via the camera element and the microphone, respectively. While capturing the video and audio data in real-time, the captured video and audio data are stored in the memory having the limited capacity, and sent to a remote server system via the communication interface for storage by the remote server system. The camera system determines that a portion of the video and audio data was not available at the remote server system. In accordance with a determination that at least some of the portion is still available in the memory having the limited capacity, the camera system resends the at least some of the portion from the memory to the remote server system via the communication interface.

    Abstract: A data streaming system includes one or more processors, memory, and a circular buffer stored in the memory. The system includes a media loader process that retrieves frames from a media source and writes the retrieved frames in chronological order to the circular buffer. The system includes a forward dispatch process that transmits frames from the circular buffer to a destination server in chronological order in real-time. The system also includes a backfill dispatch process that executes in response to receiving a backfill request from the destination server, transmitting frames from the circular buffer to the destination server in reverse chronological order.
