Abstract

A video encoder according to embodiments is configured for encoding a plurality of pictures of a video by generating an encoded video signal, wherein each of the plurality of pictures includes original picture data. The video encoder includes a data encoder configured for generating the encoded video signal including encoded picture data, wherein the data encoder is configured to encode the plurality of pictures of the video into the encoded picture data. Moreover, the video encoder includes an output interface configured for outputting the encoded picture data of each of the plurality of pictures. Furthermore, a video decoders, systems, methods for encoding and decoding, computer programs and encoded video signals according to embodiments are provided.
