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

Patent number: 11949897Abstract: The entropy coding of a current part of a predetermined entropy slice is based on, not only, the respective probability estimations of the predetermined entropy slice as adapted using the previously coded part of the predetermined entropy slice, but also probability estimations as used in the entropy coding of a spatially neighboring, in entropy slice order preceding entropy slice at a neighboring part thereof. Thereby, the probability estimations used in entropy coding are adapted to the actual symbol statistics more closely, thereby lowering the coding efficiency decrease normally caused by lower-delay concepts. Temporal interrelationships are exploited additionally or alternatively.Type: GrantFiled: January 27, 2023Date of Patent: April 2, 2024Assignee: GE Video Compression, LLCInventors: Valeri George, Anastasia Henkel, Heiner Kirchhoffer, Detlev Marpe, Thomas Schierl

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
