    Abstract: Systems and methods are presented for minimizing the suddenness and immediacy of changes to the video quality perceived by users due to bandwidth fluctuations and transitions between different bitrate streams. A method may include identifying an upcoming bitrate change in a bitstream and a nearest scene cut boundary from sync frame scene cut tags included in the bitstream. The method may include calculating whether waiting until the identified nearest scene cut boundary before changing the bitrate will cause the buffer to drop below a threshold. When the buffer is calculated to not drop below the threshold, the method may postpone the upcoming bitrate change until the identified nearest scene cut boundary.

    Abstract: Ein System umfasst einen Codierer, der konfiguriert ist, um Attributinformationen und/oder räumliche Informationen für eine Punktwolke zu komprimieren, und/oder einen Decoder, der konfiguriert ist, komprimierte Attribut- und/oder räumliche Informationen für die Punktwolke zu dekomprimieren. Um die Attribute und/oder die räumlichen Informationen zu komprimieren, ist der Codierer konfiguriert, um eine Punktwolke in eine bildbasierte Darstellung umzuwandeln. Außerdem ist der Decoder konfiguriert, um eine dekomprimierte Punktwolke basierend auf einem Bild auf der Grundlage der Darstellung einer Punktewolke zu erzeugen.

    Abstract: A video streaming method for transitioning between multiple sequences of coded video data may include receiving and decoding transmission units from a first sequence of coded video data. In response to a request to transition to a second sequence of coded video data, the method may determine whether a time to transition to the second sequence of coded video data can be reduced by transitioning to the second sequence of coded video data via an intermediate sequence of coded video data. If the time can be reduced, the method may include receiving at least one transmission unit from an intermediate sequence of coded video data that corresponds to the request to transition, decoding the transmission unit from the intermediate sequence, and transitioning from the first sequence to the second sequence via the decoded transmission unit from the intermediate sequence.
