1. Video data stream stored in a storing medium representing a video comprising
a parameter set portion indicating coding parameter settings;
a payload portion into which pictures of the video are coded in a manner parameterized using a first set of the coding parameter settings, the first set being indexed by indices comprised by the payload portion,
wherein the video data stream comprises an information comprising
an indication of a predetermined subarea of the pictures, and
replacement indices for redirecting the indices comprised 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,
wherein the second set of coding parameters are selected so that a reduced video data stream modified compared to the video data stream by
removing portions of the payload portion referring to an area of the pictures outside the predetermined subarea, and
changing location indications in the payload portion so to indicate a location in a manner measured from a circumference of the predetermined subarea instead of the pictures,
comprises a reduced payload portion having encoded thereinto subarea-specific pictures showing the predetermined subarea of the pictures in a manner parameterized using the second set of coding parameter settings,
wherein the video data stream and the reduced video data stream are conforming to HEVC, and
wherein the information is comprised in a SEI message, a VUI or a parameter set extension.
