Abstract
The present invention relates to the field of digital media recording such as video or audio, where compression is used to reduce the amount of data to save onto a data storage. In particular the invention relates to recording media, wherein the memory area required to store the media is unknown. The invention discloses a method for recording digital streamed media with a number of media frames in a memory by encoding each media frame into an encoded frame comprising a first number of quality layers, such as the quality layers in JPEG2000. The invention further relates to detecting if the data storage is full and if the data storage is full, storing new frames in the data storage previously occupied by the quality layer representing the highest resolution of the previously stored encoded frames. The invention also relates to a corresponding media recorder and computer program.
