Dynamic encoding of multiple video image streams to a single video stream based on user input

摘要

A system and method for combining multiple video bit streams on a server using low latency encoding and stream them to a user based on user input over the network. Each frame of the resulting single video stream can include anything from a single video window at full size to multiple video windows at a variety of sizes. This allows apparently instantaneous video switching by the user without the buffering start-up delay normally suffered by a user when a new video stream is selected. User browsing can be done by scrolling through smaller scale thumbnail videos and zooming of one or more of the videos. The user can also browse video based on geospatial context.
