APPARATUS AND A METHOD FOR SUPPORTING SCALABLE VIDEO CODING IN A DIGITAL VIDEO BROADCASTING SYSTEM FOR USING THE PERFORMANCE OF A PHYSICAL LAYER ZONE SYSTEM FOR AN SVC

摘要

PURPOSE: An apparatus and a method for supporting scalable video coding in a digital video broadcasting system are provided to apply SVC to a physical layer zone for supporting various users.;CONSTITUTION: Physical layer zone information including an SVC(Scalable Video Coding) component value is obtained by physical layer zone(403). The terminal receives a base layer stream and one or more enhanced layer stream(405). The terminal extracts one or more subset bit stream. The terminal decodes the extracted subset bit stream in SVC(407).;COPYRIGHT KIPO 2013;[Reference numerals] (401) Obtaining synchronization by using P1; (403) Obtaining physical layer zone information including an SVC component value by physical layer zone by PLP by using P2; (405) Receiving a basic layer stream mapped to a plurality of physical zones and one or more improvement layer streams based on an SVC component value by physical layer zone by PLP; (407) Extracting one or more sub set bit streams and decoding the SVC in order to satisfy data transfer ratio; (409) Outputting a video; (AA) Start; (BB) End
