MODULATION: 8VSB vs. OFDM

ATSC 3.0• Broadcasters are looking for opportunities to best leverage ALL core
assets• Transmission•Content•Reach (will allow SFN)
• The opportunities are more than just better television• ATSC 3.0 requirements of Broadcasters has driven multiple opportunities
associated with wireless IP broadcasting

OFDM ADVANTAGES
• OFDM has excellent robustness in multi-path environments.
• Ability to comply with world-wide regulations:
• Coexistence with current and future systems
• OFDM is spectrally efficient
• OFDM is inherently robust against narrowband interference
• Equalization is very simple compared to Single-Carrier systems

DEPLOYMENT
Over time, 1.0 ceases as new Next Gen devices replacing legacy ones
MVPDs will be expected to retransmit a station’s 1.0 signal – No Change
Importantly, gateway devices in homes will be able to receive the 3.0 transmissions and relay them within homes via traditional Wi-Fi - existing devices will be able to receive the programming from stations that have converted to the new standard.
