Abstract

THE TRANSIENT PROBLEM MAY BE SUFFICIENTLY ADDRESSED, AND FOR THIS PURPOSE, A FURTHER DELAY ON THE SIDE OF THE DECODING MAY BE REDUCED IF A NEW SBR FRAME CLASS IS USED WHEREIN THE FRAME BOUNDARIES ARE NOT SHIFTED, I.E. THE GRID BOUNDARIES ARE STILL SYNCHRONIZED WITH THE FRAME BOUNDARIES, BUT WHEREIN A TRANSIENT POSITION INDICATION IS ADDITIONALLY USED AS A SYNTAX ELEMENT SO AS TO BE USED, ON THE ENCODER AND/OR DECODER SIDES, WITHIN THE FRAMES OF THESE NEW FRAME CLASS FOR DETERMINING THE GRID BOUNDARIES WITHIN THESE FRAMES.
