A system for streaming multiple encodings of a source video stream is disclosed. A source video device system captures and/or receives source video comprising a plurality of source video frames. The source video device system encodes the source video frames into virtual frames, with each of the virtual frames being encoded using at least one different encoding parameter. The source video device system forms a container frame from the virtual frames and transmits the container frame over a network. In an example embodiment, the container frame comprises the virtual frames associated with a particular source frame and a container timestamp applicable to all of the virtual frames in the container frame.

Streaming multiple encodings encoded using different encoding parameters

A computer implemented method for managing data received from a video source device is disclosed. At least a first storage tier and a second storage tier on a storage medium are identified for respectively storing different categories of data. As data streams are received from the video source, the data streams are associated with at least the first storage tier or the second storage tier and data from the received streams are stored in the associated storage tier. When the storage medium is full or meets some other specified maximum capacity threshold, data is deleted beginning with data that has an age that exceeds one or more specified maximum retention times, followed by data with the oldest age from one or both of the first and second storage tiers.

Storage management of data streamed from a video source device

A system for streaming multiple encodings of a source video stream is disclosed. A source video device system captures and/or receives source video comprising a plurality of source video frames. The source video device system encodes the source video frames into virtual frames, with each of the virtual frames being encoded using at least one different encoding parameter. To each virtual frame is appended virtual stream identifier which is appropriate for a selected transmission mechanism. The source video device system forms a container frame from the virtual frames and transmits the container frame over a network. Devices receiving transmissions over unreliable connections may reconstruct the transmitted streams using the synchronization headers.
