摘要： Interpolation between explicitly signaled CPB (or HRD) parameters at selected bit rates is used to achieve a good compromise between CPB parameter transmission capacity and CPB parametrization effectiveness and may be, particularly, made in an effective manner.

摘要： Video codec concepts which allows more effective video composition/merging and/or a more effective implementation of gradual decoding refresh are described along with concepts of allowing video composition/merging being more effective, for instance, in terms of complexity of the composition/merging task.

摘要： 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.

摘要： A user equipment is configured to operate in a wireless communications network being operated in a TDD scheme, the TDD scheme including a plurality of TDD-frames, each TDD-frame including a guard period arranged between a downlink symbol and an uplink symbol of the TDD-frame. The user equipment is configured to receive a first number of symbols during the guard period or is configured to transmit the uplink symbol and to transmit a second number of symbols previous to transmitting the uplink symbol.

摘要： A wireless communication network, has one or more first user devices, UEs, and one or more second user devices, UEs. The wireless communication network is to configure the first UE with one or more bandwidth parts, BWPs, and with a set of control resource sets, CORESETs, within the BWP in the same slot, and the wireless communication network is to configure the second UE with only a subset from the set of CORESETs.

摘要： A user equipment for a mobile communication network is provided. The mobile communication network has a radio access network including a plurality of cells and being configured to serve the user equipment within a cell. To receive a data packet from the radio access network, the user equipment is configured to receive a plurality of different versions of the data packet transmitted by the radio access network to the user equipment in parallel via different physical resources. To provide a data packet to the radio access network, the user equipment is configured to provide a plurality of different versions of the data packet and to transmit the plurality of different versions of the data packet to the radio access network in parallel via different physical resources.

摘要： Various concepts for media content streaming are described. Some allow for streaming spatial scene content in a spatially unequal manner so that the visible quality for the user is increased, or the processing complexity or used bandwidth at the streaming retrieval site is decreased. Others allow for streaming spatial scene content in a manner enlarging the applicability to further application scenarios.

摘要： A concept for a video data stream extraction is presented which is more efficient namely which is, for example, able to more efficiently deal with video content of a type unknown to the recipient with videos of different type differing, for instance, in view-port-to-picture-plane projection, etc., or which lessens the extraction process complexity. Further, a concept is described using which a juxtaposition of different versions of a video scene, the versions differing in scene resolution, may be provided more efficiently to a recipient.
