Abstract: Apparatuses and methods for checking a data stream on trustworthiness are described. According to an aspect, the data stream indicates, whether a segment is a first segment or whether a segment is a last segment of assigned sequence of segments. According to another aspect, an apparatus for decoding a data stream is configured for deriving, from the data stream, whether a verification chain within a temporal sequence of segments is interrupted at a segment.

Abstract: An apparatus for checking a video data stream on trustworthiness derives a number of substreams of a predetermine temporal segment out of a sequence of temporal segments, in units of which the video data stream is checkable on trustworthiness, and further derives dependency information, which indicates, for the substream, whether the substream is dependent or whether the substream depends on one or more reference substreams. The trustworthiness check is performed by forming a verification stream based on a hash value, which is obtained from a portion of the substream to be verified and based on a reference hash value. If the substream is independent, a hash value derived for a corresponding substream of the preceding temporal segment is used as the reference hash value.

Abstract: A motion-vector wrap-around coding tool may be reliably used, for instance, in the context of segmental video bitstream formation under switching between different video bitstream representations. A video encoder encodes a video and an indication into a data stream, which is valid for a sequence of pictures, and indicates that certain or all Random Access Skipped Leading (RASL) pictures within the sequence of pictures are coded in a manner excluding a predetermined set of one or more coding tools which includes a wrap-around motion compensation tool. A video decoder decodes from a data stream an indication that indicates that certain or all RASL pictures within a sequence of pictures are coded in a manner excluding a predetermined set of one or more coding tools including a wrap-around motion compensation tool.
