In ATSC the modulation type can be 8VSB for over the air DTV and QAM64 or QAM256 for Digital Cable. > 3.) ATSC frequency is basically given in Hz? > Does this also apply for satellites?

Although ATSC's PSIP table can carry information about satelite-reception. regards, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/
