METHOD AND SYSTEM FOR ENCODING AN INPUT VIDEO STREAM INTO A COMPRESSED OUTPUT VIDEO STREAM WITH PARALLEL ENCODING

摘要

A method is disclosed performed by a system (10), for encoding an input video stream into a compressed output video stream, the input video stream comprising a plurality of data frames, the system comprising a first system node (12) and a second system node (14). The method comprises receiving, at the first node (12), a first data frame of the input video stream, receiving at the second node (14), a second data frame of the input video stream and producing, at the first node, dependency data representing a dependency between the first data frame and the second data frame, based on the first data frame. The method further comprises sending, by the first node to the second node, information on the produced dependency data, producing, at the second node, a compressed representation of the second data frame based on the second data frame and the received information on the dependency data, producing a compressed representation of the first data frame based at least on the first data frame, and combining the compressed representation of the first data frame and the compressed representation of the second data frame into the compressed output data stream.
