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.

A method of encoding a video stream for the provision of a prunable video stream, comprising:
- receiving, in an encoder, a video stream in which each image frame of the video stream is divided into a number of subviews,
- assigning a category to each subview in each image frame of the video stream based on a content of the particular subview,
- monitoring the assigned category for each subview in each image frame of the video stream and identifying any change in the assigned category for the particular subview in relation to a previous image frame,
- encoding the video stream to create an encoded video stream using hierarchical multi-layer encoding, in such manner that, for each subview in each image frame of the video stream, each change in the assigned category for the particular subview in relation to the previous image frame starts a new hierarchical P-frame structure for the particular subview.
