How Discover Video Calculates Streaming & File Storage

  • Discover Video uses 10242 for a MB rather than 1000 to be more consistent with file systems. For example, the Windows system uses 1,048,576 (10242) bytes per MB.
  • Actual file size may vary depending on the amount of motion and the compression used. It is unlikely to be larger than the calculated value.
  • For multicast, the total streaming bandwidth is always equal to the streaming rate, regardless of the number of viewers.
  • Internet Streaming Bandwidth is only used when there is one or more viewers. No bandwidth is used when there are no viewers except for the encoder sending the stream.
  • Bandwidth use is the same whether the viewer is consuming a live video stream or a file-based video stream, although a file may use more due to client-side buffering/caching.
  • VoD files are cached on SignStick, so there is minimum bandwidth used.
  • Discover Video Streaming Service provides X GB of streaming bandwidth, and Y GB of file storage for Z dollars.
