Method and system for encoding video streams

Abstract

A method and a video encoding system for encoding a video stream include video data representing sequentially related image frames, wherein the image frames include a predefined first subarea and a predefined second subarea. The method comprises defining a first bitrate budget, defining a second bitrate budget, encoding the video stream including applying the first bitrate budget to video data of the first subarea and applying the second bitrate budget to video data of the second subarea. The video encoding system comprises an image processor for processing the image stream, a memory including values defining a first bitrate budget and a second bitrate budget, respectively, and a first subarea and a second subarea of the image frames of the image stream and an encoder arranged to encode the image stream, the encoding including applying the first bitrate budget to video data of the first subarea and applying the second bitrate budget to video data of the second subarea.
