A media device allows users to watch and capture portions from a media stream. According to the invention, the means for coding the frames as a frame structure or as a field structure are able to choose the field or frame structure dynamically as a function of the measurements of spatial and temporal activity of the said frame. A virtual printer intercepts a spooled printed job and saves the associated enhanced metafile. The first field indicates a first data type and the second field indicates a second data type, wherein the second data type is different than the first data type. A retort container comprises a body portion including a base and outer side walls extending from the base to a mouth portion defining an opening and a resealable lid for selectively hermetically sealing the opening in the container and alternatively opening the container for removal of the flexible packages containing foodstuff.
