It is possible that certain signals transmitted on the Internet could be treated like signals emanating from a satellite that has a footprint covering the entire planet. In order to enforce territorial restrictions, this approach would require that the signals be encrypted and that the decoders be made available only within the United States. This approach requires, however, that those engaged in Internet retransmissions adopt a subscription model. In addition, extreme caution should be exercised not to overextend the analogy to satellite transmissions. Certain implementations of this approach may not be as technologically sound as existing systems for preventing unauthorized reception of satellite signals and, unlike satellite decoders, personal computers connected to the Internet are capable of retransmitting a signal once decoded.
