Broadcast television isn't widely available in 4K for several technical, regulatory, and economic reasons: 1. Bandwidth Limitations Over-the-Air (OTA) Broadcasting: TV stations rely on limited radio frequency spectrum allocated by the FCC. Transmitting 4K signals requires significantly more bandwidth than HD signals, which would either reduce the number of channels a station can broadcast or require new spectrum allocations. Compression Technology: While technologies like HEVC (H.265) help compress 4K signals, their widespread adoption in broadcasting is still evolving. 2. Infrastructure Challenges Broadcasters' Equipment: Many stations would need to upgrade their cameras, transmission equipment, and production workflows to handle 4K content, which is a costly investment. Consumer Antennas: Existing antennas may not always support the newer transmission standards required for 4K. 3. Regulatory and Standardization Delays ATSC 3.0 Transition: The Advanced Television Systems Comm...
