Title:
METHOD AND APPARATUS OF BITSTREAM RANDOM ACCESS AND SYNCHRONIZATION FOR MULTIMEDIA APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2017/024990
Kind Code:
A1
Abstract:
A method and device for switching Representations are disclosed. On the server side, leading-picture information associated with leading pictures in an open GOP (group of picture) is signalled in a media presentation description. Each leading picture corresponds to one picture preceding a RAP (Random Access Picture) picture in a segment in an output order and being coded depending on the RAP picture. At the client side, an original Representation and a target representation are received and the leading-picture information for the target Representation is determined from the media presentation description received. A switched presentation is presented, where the switched presentation switches from the original Representation to the target Representation by switching presentation from pictures in the original Representation to pictures in the target Representation at a stream access point (SAP) corresponding to the RAP picture in one segment of the target representation determined according to the leading picture information.
