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 1):
A method of media communication for a server and a client device, the method comprising:\n dividing a video bitstream into segments, wherein each segment belongs to a segment-type group including an open-GOP (Group of Pictures) type, wherein pictures in each segment having the open-GOP type are coded with zero or more leading pictures, and wherein each leading picture corresponds to one picture preceding a RAP (Random Access Picture) picture of the segment in an output order and being coded depending on the RAP picture of the segment and possibly one other picture in a previous segment; and signalling leading-picture information in Representation, Adaptation Set, a media presentation description, or a similar description file comprising information about video stream content, wherein the leading-picture information is associated with a number of said zero or more leading pictures in each segment having the open-GOP type.
