The invention provides data for display on the display area for a child frame when the child frame is synthesized and displayed on the parent frame in picture-in-picture playback in order to give the displayed area of the child frame in conformity with the video content in the parent frame, as well as providing a video display apparatus etc. By limiting the amounts of activating compounds during the preparation of such polymers, the reactivity is sharply decreased, yet can be increased by addition of suitable catalysts. The first metal insulating sub-layer has sharp profiles due to a step height difference in the metal interconnection layer pattern. Each of a plurality of stations is associated with one of the plurality of symbols and each of the plurality of stations receives the objects bearing the associated symbols. A second portion of the reconciliation rule may be processed using the retrieved data from the second data source to generate a second result. A source electrode including a source material may be inserted into the conductive substrate.
