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.

Claim (Index 19):
A client device for switching representations, the client device comprising:\n an interface arranged to establish a communication connection with a server; and one or more electronic circuits or processors configured to: receive media presentation description for video stream content, wherein the media presentation description corresponds to Adaptation Sets and Representations including an original representation and a target representation; receive the original representation, wherein the original representation comprises multiple first segments having first GOP (group of picture) structure; receive the target representation, wherein the target representation comprises multiple second segments having second GOP structure; determine leading-picture information from the media presentation description, wherein the leading-picture information associated with zero or more leading pictures in each second segment, and each leading picture corresponds to one picture preceding a RAP (Random Access Point) picture of each second segment in an output order and being coded depending on the RAP picture of each second segment and possibly one other picture in a previous second segment; and present a switched presentation 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 of each second segment determined according to the leading-picture information.
