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.
Claims15
A method of encoding a video stream for the provision of a prunable encoded video stream, comprising,
- in an encoder, encoding frames of the video stream into encoded frames of a base-layer,
- identifying, in the video stream, a first event-generating occurrence in one or more frames of the video stream,
- in the encoder, using the identified event-generating occurrence to initiate a hierarchical branch in an enhanced layer referring to an intra-encoded frame of the base-layer, and
- after initiating the hierarchical branch, encoding frames of the video stream into encoded frames of the enhanced layer, wherein each inter-encoded frame of the enhanced layer refers to the intra-encoded frame of the base layer or to another inter-encoded frame of the enhanced layer.

A camera configured to perform a method of encoding a video stream for the provision of a prunable video stream, comprising:
- an encoder, configured to encode frames of the video stream into encoded frames of a base-layer;
- an image processor configured to identify, in the video stream, a first event-generating occurrence in one or more frames of the video stream;
- the encoder further configured to use the identified event-generating occurrence to initiate a hierarchical branch in an enhanced layer referring to an intra-encoded frame of the base-layer, and
- after initiating the hierarchical branch, encode frames of the video stream into encoded frames of the enhanced layer;
- and
- a communication interface configured to transmit the video stream, wherein each inter-encoded frame of the enhanced layer refers to the intra-encoded frame of the base layer or to another inter-encoded frame of the enhanced layer.
