Network-Loss Tolerant Mobile Broadcast Systems and Algorithms

摘要

Systems and Algorithms for a network-loss tolerant, mobile broadcasting system that reliably and efficiently address unreliable or untimely transmission of segments. By associating a unique metadata to each segment (an Upload ID), segments are identified by the order in which they were captured at their source. Upload IDs allow for methods to proactively address lost or out-of-order segments without disturbing a broadcast. Late arriving segments are preserved for broadcast in the correct sequence by the invention's novel uses of Upload IDs.

主权项

1. A system for mobile broadcasting, comprising:
a video camera which:
captures video;creates segments from said video;generates metadata Upload IDs for said segments that identifies the sequence of said segments creation;transmits said segments and said Upload IDs; a server, comprising:
an upload handler which:
receives said segments and said Upload IDs transmitted by said video camera;transfers said segments and said Upload IDs transmitted by said video camera;a broadcast module which:
receives said segments and said Upload IDs;creates a segment playlist using said segments and said Upload IDs;at least one viewing module contained in, or accessed by, at least one viewing device which:
accesses said segment playlist;presents said segments.
