Abstract: A receiver that receives a digital signal transmitted on the basis of an orthogonal frequency division multiplexing (OFDM) method. This receiver comprises a demodulation unit for demodulating the digital signal, a demapping unit for demapping demodulated data output from the demodulation unit, a frequency deinterleave unit for executing a frequency deinterleaving process on data output from the demapping unit, a delay unit for delaying control information superposed on the digital signal by a prescribed time period, and a time deinterleave unit for executing, on the basis of the interleave length specified by the control information delayed by the delay unit, a time deinterleaving process on data on which the frequency deinterleaving process has been executed.

Abstract: An apparatus for providing a visual lightning effect includes a first chamber and a second chamber, where a passageway connects the first chamber and the second chamber. An inert gas is provided within the first chamber, the second chamber, and the passageway. A first contact is located external to the first chamber; and a second contact is located external to the second chamber, wherein an electrode provides a charge to the second contact, wherein the charge causes an electrical discharge between the second contact and the first contact via channels provided by fill material located within the second chamber that traverses the passageway to the first chamber, thereby resulting in the brilliant visual lightning effect.
