Abstract: A method for encoding a video stream for the provision of prunable video data, comprising identifying, in the video stream, a first event-generating occurrence in one or more frames of the video stream, and, in an encoder, using the event-generating occurrence to initiate a hierarchical branch extending from a base-layer when encoding the video stream.

Abstract: A method of encoding a video stream for the provision of prunable video data, comprising: receiving, in an encoder, a video stream in which each image frame of the video stream is divided into a number of subviews, providing each subview with an assigned category based on a content of the particular subview, monitoring the evolution of category assigned for each subview, and encoding the video stream using a hierarchical P-frame encoding structure, in such manner that each change in category for a subview starts a new hierarchical P-frame structure.
