Digitized Broadcast Signals

摘要

Methods, systems, and computer-readable media can facilitate digitizing a broadcast transmission and transporting the digitized broadcast transmission along with one or more digitized narrowcast transmissions to a subscriber. In embodiments, a digitized broadcast transmission and one or more digitized narrowcast transmissions can be separately demodulated and the transmissions can be combined at one or more receiving nodes. In embodiments, a digitized broadcast transmission can be combined with one or more digitized narrowcast transmissions. Lossless compression and de-compression techniques can be used to optimally transport digitized broadcast and narrowcast signals.

主权项

1. A method comprising:
receiving an analog broadcast signal; receiving one or more analog narrowcast signals; converting the analog broadcast signal into a digital broadcast signal; converting the one or more analog narrowcast signals into digital narrowcast signals; combining the digital broadcast signal and the one or more digital narrowcast signals, thus generating a single output signal; and outputting the single output signal to a downstream network component.
