A translator includes: an input configured to receive a bit stream having a plurality of digitally encoded contents and control information; processing circuitry configured to select one of the digitally encoded contents, to use the selected digitally encoded content to produce an analog modulated signal, to use the digitally encoded contents to produce a digitally modulated signal, and to combine the analog modulated signal and the digitally modulated signal to produce a hybrid signal; and an output configured to output the hybrid signal. A method performed by the radio signal translator is also provided.

A translator comprising: an input configured to receive a bit stream having a plurality of digitally encoded contents and control information; processing circuitry configured to select one of the digitally encoded contents, to use the selected digitally encoded content to produce an analog modulated signal, to use the digitally encoded contents to produce a digitally modulated signal, and to combine the analog modulated signal and the digitally modulated signal to produce a hybrid signal; and an output configured to output the hybrid signal. Claim: 2. The translator of claim 1, wherein: the digitally encoded contents comprise protocol data units or data frames produced by a broadcast content source. Claim: 3. The translator of claim 2, wherein: the protocol data units comprise layer 2 protocol data units. Claim: 4. The translator of claim 2, wherein the content source is an HD Radio broadcaster. Claim: 5. The translator in claim 4, wherein the processing circuitry selects digitally encoded content for the analog modulated signal that differs from the digitally encoded content used by the HD Radio broadcaster for a main program signal. Claim: 6. The translator of claim 2, wherein the content source is a network operations center. Claim: 7. The translator in claim 6, wherein the processing circuitry selects digitally encoded content for the analog modulated signal that differs from the digitally encoded content used by the network operating center for a main program signal. Claim: 8. The translator in claim 1, wherein the processing circuitry is further configured to: reorder data in the digitally encoded contents; and replace bits in the digitally encoded contents. Claim: 9. The translator of claim 1, wherein the processing circuitry is configured to modify audio processing of the selected digitally encoded content. Claim: 10. A method of distributing content, the method comprising: receiving a bit stream at an input of a translator, wherein the bit stream includes a plurality of digitally encoded contents and control information; selecting one of the digitally encoded contents; using the selected digitally encoded content to produce an analog modulated signal; using the digitally encoded contents to produce a digitally modulated signal; combining the analog modulated signal and the digitally modulated signal to produce a hybrid signal; and outputting the hybrid signal. Claim: 11. The method of claim 10, wherein: the digitally encoded contents comprise protocol data units or data frames produced by a content source. Claim: 12. The method of claim 11, wherein the content source is an HD Radio broadcaster, and a configuration of digital sidebands in the hybrid signal of the remote broadcaster differs from a configuration of digital sidebands used by the HD Radio broadcaster. Claim: 13. The method in claim 12, wherein the content source is an HD Radio broadcaster, and the selected digitally encoded content for the analog modulated signal that differs from the digitally encoded content used by the HD Radio broadcaster for a main program signal. Claim: 14. The method of claim 11, wherein the content source is a network operations center. Claim: 15. The method of claim 11, wherein: the protocol data units comprise layer 2 protocol data units. Claim: 16. The method of claim 10, further comprising: reordering data in the digitally encoded contents. Claim: 17. The method of claim 10, further comprising: replacing bits in the digitally encoded contents. Claim: 18. The method of claim 11, further comprising: modifying audio processing of the selected digitally encoded content. Claim: 19. A method of distributing content, the method comprising: transmitting a bit stream of unmodulated HD Radio Layer 2 data over a network, the data representing a plurality of digitally encoded contents and control information formatted according to an HD Radio protocol; receiving the unmodulated HD Radio Layer 2 data at a player; using processing circuitry in the player to decode the bit stream to recover the contents and control information; supplying user commands to the processing circuitry; and producing an audio output based on one of the contents in response to the user commands. Claim: 20. The method of claim 19, wherein the contents includes a plurality of programs and the audio output is based on one of the programs selected by the user commands.
