An oblique correlation detection section detects correlation in an oblique direction of a composite video signal. The host device includes a processor and a control mechanism. The outputted tag includes a media reference and a user identification. One end of each heat dissipating sheet has an inclined extending portion which has two parallel sides and is inclined to other portion of the heat dissipating sheet. The method also includes comparing the first digital representation to at least the second digital representation contained in the data structure and if there is a match between the first digital representation and at least the second digital representation contained in the data structure, transmitting a message to a remote server indicating the match. By lowering this moisture content to 77 ngcm3 or below, an organic EL panel can be realized where the degradation of luminescence characteristics is minimized.
