generating a specified set of transport streams from the set of input streams, wherein the specified set of transport streams includes a new transport stream having a first set of input streams selected from more than one of the multiple transport streams, wherein a first quantity of transport streams in the specified set is different from a second quantity of transport streams in the multiple transport streams; and
transmitting the specified set of transport streams to a receiving device, wherein the new transport stream is transmitted as a new transponder signal.

2. The method of claim 1 , wherein generating the specified set of transport streams includes generating the first new transport stream in which all input streams of the first set of input streams are video streams.

3. The method of claim 1 , wherein generating the specified set of transport streams includes generating the new transport stream in which all input streams of the first set of input streams are informational data streams.

4. The method of claim 3 , wherein at least one of the informational data streams is generated by compiling informational data from two or more of the multiple input streams from one or more of the multiple transport streams.

5. The method of claim 4 , wherein the at least one of the informational data streams is program acquisition table/program map table (PAT/PMT) informational data that is generated by compiling the PAT/PMT informational data from two or more of the multiple transport streams.

6. The method of claim 4 , wherein the at least one of the informational data streams is network information table/network address translation (NIT/NAT) informational data that is generated by compiling the NIT/NAT informational data from two or more of the multiple transport streams.

7. The method of claim 4 , wherein the at least one of the informational data streams includes signal quality informational data, which indicates signal strength information for two or more of the multiple transponder signals corresponding to the two or more of the multiple transport streams from which the signal quality is compiled.

8. The method of claim 4 , wherein the at least one of the informational data streams includes low-noise frequency block downconverter with integrated feedhorn (LNBF) informational data, which provides diagnostic and status information for each of the LNBFs of a receiving antenna that receives the multiple transponder signals.
