METHOD AND APPARATUS FOR ADAPTATION OF SCALABLE VIDEO CORDING TO PACKET LOSS

摘要

PURPOSE: An adaptation apparatus for reducing packet loss errors of a scalable video cording and a method thereof are provided to remove low dependent packet by analyzing the dependability between scalability layers. CONSTITUTION: A packet scheduler(205) is connected to a scheduling buffer in a node of an IP network which receives a packet from multiple paths. If it is considered the loss of input packets, the packet scheduler removes a low dependent packet in consideration of the dependability between scalability layers. The packet scheduler provides a packet multiplexer with the input packet from which the low dependent packet is removed. A packet loss detection unit(203) detects the packet loss pattern of each NAL by reading out the NALU(Network Abstraction Layer Unit) of the inputted scalable video.
