Summary:The present application relates to a method for embedded video compression comprising receiving image data. The method comprises compressing the image data into compressed data blocks with a predefined data rate by using a video compression mode. The method comprises compressing the image data into compressed data blocks with the predefined data rate by using a graphic compression mode, wherein the predefined data rate defines a target code size of a compressed data block. The method comprises detecting whether a code size of the data block does not meet the target code size. The method comprises quantizing at least one input pixel of the image data in case a code size of the data block does not meet the target code size. The present application relates also to a method for embedded video decompression, an apparatus for embedded video compression and an apparatus for embedded video decompression. Furthermore the present application relates to a system comprising said apparatus for embedded video compression and said apparatus for embedded video compression and to a computer readable medium having a computer program stored thereon for performing said method for embedded video compression and said method for embedded video decompression.
