Title:
METHOD FOR PROCESSING A COMPRESSED VIDEO STREAM
Document Type and Number:
WIPO Patent Application WO/2012/098078
Kind Code:
A3
Abstract:
The invention provides a method for processing a compressed video stream consisting of a sequence of compressed data packets. Each compressed data packet is assigned to a frame by processing the undecoded data packet, wherein a frame consists of one or more data packets. A first plurality of frames is assigned to a first sliding window (Win1) and a second plurality of frames is assigned to a second sliding window (Win2) wherein the first and the second sliding windows consist of at least partially different frames. A first window indicator will be calculated by determining a first indicator representing an average number of data packets per frame (ANORPwin1) within the first window (Win1), and/or a second indicator representing a size information of the data within the first window (Win1). A second window indicator will be calculated by determining a third indicator repre- senting an average number of data packets per frame (ANORPwin2) within the second window (Win2), and/or a forth indicator representing a size information of the data within the second window (Win2). A comparison based on the first and the second window indicators is made.
