A system and method for hijacking inodes based on replication operations received in an arbitrary order is used to assist a data replication operation from a source storage system to a destination storage system. The filter unit filters the video data VIN to convert the video data VIN into video pictures formated with a different number of columns andor lines, and provides a filtered video signal indicative thereof. Respiration is implantably sensed and respiration data is stored by an implantable device. This arrangement reduces interference fringes in the amplifier.
