A pair of plate benders are provided for bending a bone plate. On detecting a fade in the video signal, an order in which frames are coded is changed such that referenced frames are positioned immediately before and after the fade and a pyramidal structure of bidirectionally coded frames are used for the duration of the fade. The intrinsic layer is disposed on the front surface of the silicon substrate. This association is maintained in the meta data store, so that whenever a change is made to meta data for one piece of content, then the meta data for the associated piece is also changed.
