Zusammenfassung:An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate an MPEG packet data stream. The second circuit may be configured to (i) scramble the data stream to generate a scrambled data stream, (ii) encode the scrambled data stream to generate an encoded data stream, (iii) interleave the encoded data stream, (iv) encode the interleaved data stream, (v) modulate the encoded data stream, and (vi) filter the modulated data stream.
