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 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 sub-area 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： In the field of wireless communication networks or systems in which a user equipment is configured with semi-persistent scheduling, a first aspect of the invention provides for continuous or non-interrupted SPS of the user equipment after a handover, and a second aspect of the invention provides an enhanced control signaling for a user equipment configured with SPS to reduce the signaling overhead.
