1. Server comprising an electronic circuit or a microprocessor configured to provide a manifest file to a client, the manifest file relating to a download of a video using tile-based streaming, the manifest file comprising:
first parameter sets defining picture-portion specific adaptation sets of one or more representations, each picture-portion specific adaptation set being specific for a corresponding picture portion among different picture portions of the video with the one or more representations of the respective picture-portion specific adaptation set having the corresponding picture portions encoded thereinto, wherein each picture portion is encoded into more than one representation of the picture-portion specific adaptation sets at different qualities, wherein the first parameter sets define a quality level for each representation of the picture-portion specific adaptation sets;
second parameter sets each related to a corresponding region of interest and defining a preselection adaptation set which assigns to each of the different picture portions, one of the picture-portion specific adaptation sets,
wherein
the manifest file comprises an indication whether the quality levels indicated by the first parameter sets are defined on a common ordinal scale so that each quality level is comparable with all remaining quality levels of the first parameter sets on the common ordinal scale; and
each second parameter set comprises
one or more parameters indicating, for each of the different picture portions, a quality level hint for the respective picture portion and an indication whether the quality level hints for the different picture portions and the quality levels defined by the first parameter sets are defined on the common ordinal scale so that the quality level hints and the quality levels are comparable with each other on the common ordinal scale.
