METHOD FOR STORING AND ANALYZING PLAY RELATION BETWEEN OBJECTS FOR AN OBJECT BASED AUDIO SERVICE AND VOLUME INFORMATION AND A DEVICE THEREOF, CAPABLE OF EFFICIENLTY TRANSMITTING PLAY RELATION BETWEEN OBJECTS AND PLAY VOLUME INFOMRATOIN IN AN OBJECT BASED AUDIO BIT STREAM

摘要

PURPOSE: A method for storing and analyzing play relation between objects for an object based audio service and volume information and a device thereof are provided to predefine and store play relation between objects and forcible/constraint conditions for play volume and enable a terminal to efficiently analyze the forcible/constraint conditions and the play relation.;CONSTITUTION: An object based audio player(101) inputs audio track information and forcible/constraint information included in an object based audio file(102) to a forcible/constraint information analyzing module(103). The forcible/constraint information analyzing module analyzes the inputted information to select a track to be decoded. The forcible/constraint information analyzing module constrains play volume information of a track in a mixing step. An operation of an object based audio player to which forcible/constraint information is reflected is performed.;COPYRIGHT KIPO 2010
