Publication number: 20240155141Abstract: The handling of scalable data streams by network entities is rendered less complex by, in the data stream, accompanying packets which actually carry data by packets of a different packet type which have a scalability axes descriptor defining the number of scalability axes and a semantic meaning thereof. In another aspect, the handling of scalable data streams by network entities is rendered more efficient by conveying level and/or profile descriptors using packets other than the data carrying packets, with profile and/or level descriptors being divided up into a first set explicitly signaling the definition of the available coding option set and/or available syntax element value range for a respective operation point, and a second set of profile and/or level descriptors which signal the definition of the available coding option set and/or available syntax element value range for their respective operation points by reference another profile and/or level descriptor.Type: ApplicationFiled: January 12, 2024Publication date: May 9, 2024Inventors: Thomas SCHIERL, Valeri GEORGE, Anastasia HENKEL, Detlev MARPE, Karsten GRÜNEBERG, Robert SKUPIN

Patent number: 11956472Abstract: Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.Type: GrantFiled: July 26, 2023Date of Patent: April 9, 2024Assignee: GE Video Compression, LLCInventors: Thomas Schierl, Valeri George, Anastasia Henkel, Detlev Marpe, Karsten Grueneberg, Robert Skupin

Publication number: 20230421824Abstract: For transmitting a panorama video having a resolution higher than a decoder can decode, at a transmitter side, encoded data coding different (groups of) spatial segments of a video picture of a video stream are packetized into separate substreams, to obtain a group of separate substreams. At a receiver side, from the group of separate substreams a proper subset of the separate substreams is extracted and combined to a data stream containing encoded data coding respectively a proper subset of the spatial segments or groups of subsequent spatial segments of the video picture of the video stream. Thus, a decoder may decode only a subregion of the video picture of the video stream, the subregion being defined by the spatial segments or groups of spatial segments coded in the encoded data contained in the data stream.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Inventors: Karsten GRÜNEBERG, Serhan GÜL, Cornelius HELLGE, Yago SÁNCHEZ, Thomas SCHIERL, Robert SKUPIN

Patent number: 11770546Abstract: A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.Type: GrantFiled: December 15, 2020Date of Patent: September 26, 2023Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Robert Skupin, Yago Sánchez De La Fuente, Thomas Schierl, Cornelius Hellge, Karsten Grüneberg, Thomas Wiegand

Publication number: 20230015840Abstract: File format concepts for video files are described. It is proposed to that descriptive data of a file indicates whether a parameter set for a track of a file is forwarded when jointly decoding a sub-stream of the track and a further track, and/or that a file includes, for a sub-stream of a video stream signaled in the file, an alternative parameter set to a parameter set for fully decoding the track, the alternative parameter set being for decoding the sub-stream, so as to allow for switching between multiple tracks of a file, and/or that step-wise stream access pictures of a track of a file are marked as stream access point pictures for accessing the track, and/or that a temporal length within which a decoder refresh in case of a joint decoding of sub-streams distributed over multiple tracks is indicated in a file, and/or that a file provides information from which it is derivable whether a pixel aspect ratio varies.Type: ApplicationFiled: September 29, 2022Publication date: January 19, 2023Inventors: Yago SÁNCHEZ DE LA FUENTE, Dimitri PODBORSKI, Karsten GRUENEBERG, Cornelius HELLGE, Thomas SCHIERL, Robert SKUPIN, Thomas WIEGAND

Publication number: 20220264127Abstract: Parallel processing concepts such as wavefront parallel processing, are realized with a reduced end-to-end delay by giving up the usual slice concept according to which slices are either coded/decoded completely independent from areas of the picture outside of the respective slice, or at least independent from areas outside the respective slice as far as the entropy coding is concerned, namely in favor of slices of different modes, namely ones called dependent slices which allow for interdependencies across slice boundaries, and others which do not, called normal slices, for example. Combined with the aspect or not, WPP processing concept is made more efficiently by using the slices' start syntax portions to locate WPP entry points.Type: ApplicationFiled: March 8, 2022Publication date: August 18, 2022Inventors: Thomas SCHIERL, Valeri GEORGE, Anastasia HENKEL, Detlev MARPE, Karsten GRÜNEBERG, Robert SKUPIN
