A system and method for providing reliable, legally compliant access to geographically restricted ATSC television signals via user-owned devices hosted in a datacenter. The invention verifies the physical address of each applicant to ensure eligibility within the designated market area before installation. It eliminates the need for rooftop or indoor antennas, resolving common ATSC reception challenges, including interference, terrain obstruction, and lightning risks. Designed for ease of use by non-technical users, the system provides consistent high-quality reception through a managed datacenter infrastructure. The invention complies with legal boundaries set by the U.S. Supreme Court's ruling in ABC v. Aereo by ensuring individualized device ownership and avoiding centralized retransmission. An optional encrypted group addressing mode further reduces energy and hardware redundancy while enforcing regional access through a conditional access system with access limited to persons with validated addresses and members of the datacenter.

Methods are generally described for inaudible orthogonal signal communication. An example method includes determining, based on an input message, a series of symbols, where each symbol from the series of symbols represents a numerical value, wherein each symbol from the series of symbols corresponds to a band-limited white noise tone orthogonal to each other band-limited white noise tone corresponding to each other symbol. The example method also includes generating a sub-token comprising each symbol from the series of symbols, where each symbol overlaps in time with at least one other symbol. The example method also includes modulating a carrier wave with the sub-token to produce a signal audio waveform, where the modulation uses a spread spectrum technique, and providing the signal audio waveform to a television device, where the television emits the signal audio waveform as a low-amplitude audio signal.
