Multi-resolution pyramid for georeferenced video

A system for delivering overhead video to a computing device, the system comprising:

• non-transitory data storage configured to store overhead video;
• computing hardware in communication with the non-transitory data storage, the computing device configured with instructions to execute:
• a transcoding module configured to generate a transcoded video from the overhead video, the transcoded video having a multi-scale, pyramidal data format and including georeferencing coordinates and time synchronization information;
• a rendered video storage module configured to store the transcoded video in one or more transcoded video files on the non-transitory data storage;
• and
• a caching module configured to respond to requests for overhead video data from the computing device by:
• retrieving a primary video stream comprising transcoded video files for a geographical region;
• caching a secondary video stream comprising transcoded video files from geographical regions proximal to the geographical region;
• and
• transmitting to the computing device the primary video stream and at least one of the cached transcoded video files of the secondary video stream.

Non-transitory computer storage configured with executable instructions for delivering overhead video data, the executable instructions comprising:

• a transcoding module configured to transcode overhead video into multiple video streams and to encode the multiple video streams with georeferencing coordinates and time synchronization information;
• a caching module configured to retrieve a primary video stream comprising a video stream that includes overhead video of a geographical region and to retrieve a plurality of secondary video streams comprising video streams that include imagery of geographical regions adjacent to the geographical region;
• and
• a transmission module configured to send the primary video stream and the plurality of secondary video streams over a network to a receiving computing device,
• wherein the primary video stream has a frame rate that is greater than a frame rate of each of the plurality of secondary video streams.
