Abstract: Data streaming includes: sending a first media data stream to a destination; detecting that a portion of the first media data stream needs to be resent; and sending to the destination a second media data stream. The second media data stream comprises media data that corresponds to at least some of the portion of the first media data stream; and in the second media data stream, data that is obtained more recently is resent prior to data that is obtained less recently.

Abstract translation: 数据流包括：向目的地发送第一媒体数据流; 检测到第一媒体数据流的一部分需要重新发送; 并向目的地发送第二媒体数据流。 所述第二媒体数据流包括对应于所述第一媒体数据流的所述部分中的至少一部分的媒体数据; 并且在第二媒体数据流中，最近获得的数据在最近获得的数据之前重新发送。

Abstract: A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera, where at least some of the live video stream is recorded at a remote server; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.

Abstract: A data streaming method is performed at a computing device having one or more processors and memory. The memory stores one or more programs configured for execution by the one or more processors. The process records video from a camera in real-time. The recorded video is stored in the memory in a circular buffer in chronological order. The process sends data in chronological order from the circular buffer to a destination in real-time. In response to detecting that a portion of content from the circular buffer needs to be resent, the process concurrently resends to the destination in reverse chronological order data from the portion of content from the circular buffer.

Abstract: A method at a server system includes: receiving a video stream from a remote video camera, wherein the video stream comprises a plurality of video frames; selecting a plurality of non-contiguous frames from the video stream, the plurality of non-contiguous frames being associated with a predetermined time interval; encoding the plurality of non-contiguous frames as a compressed video segment associated with the time interval; receiving a request from an application running on a client device to review video from the remote video camera for the time interval; and in response to the request, transmitting the video segment to the client device for viewing in the application.

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.
