A method for operating an internal combustion engine in whose exhaust gas region at least one SCR catalytic converter is arranged, a reagent which contributes to NOx conversion in the SCR catalytic converter being applied to said SCR catalytic converter, and a device for carrying out the method are proposed. The composite channel may be a static channel that contains different original channels of content in different locations on a displayed page, or may be a dynamic channel that is processed by the receiver to display a multiple different video streams on a single display device. Next, the method comprise extracting the return URL embedded in the information and comparing, the return URL to a reference return URL corresponding to the web-based interface hosted by the merchant web site. The invention has application in a wide variety of data transmission schemes including Asymmetric Digital Subscriber Line systems that includes the transmission of signals over twisted pair, fiber andor hybrid telephone lines, cable systems that includes the transmission of signals over a coaxial cable, and digital cellular television systems that include the transmission of radio signals. The support plate is configured to be mounted to a second side of the photovoltaic module. The detector is attached to at least one of the first stage and the second stage.
