Here's a breakdown of how ATSC 3.0 improves on ATSC 1.0:
- Better Picture and Sound Quality
Resolution: ATSC 3.0 supports 4K UHD (Ultra High Definition) resolution, whereas ATSC 1.0 is limited to HD (720p or 1080i).
HDR Support: ATSC 3.0 includes High Dynamic Range (HDR), which provides brighter highlights, deeper blacks, and more vivid colors.
Audio: It supports Dolby AC-4, which enables immersive sound formats like Dolby Atmos. This is a significant step up from the audio in ATSC 1.0.
- Enhanced Reception
Better Signal Resilience: ATSC 3.0 uses OFDM (Orthogonal Frequency Division Multiplexing) technology, which is more robust against interference and better for mobile and indoor reception compared to the 8VSB modulation of ATSC 1.0.
Mobile Viewing: Signals are optimized for mobile devices, meaning you can watch OTA broadcasts on smartphones, tablets, and other portable devices.
- More Channels and Services
Efficient Bandwidth Usage: ATSC 3.0 can deliver more channels within the same spectrum thanks to better compression (HEVC vs. MPEG-2 in ATSC 1.0).
Datacasting: In addition to TV content, broadcasters can transmit data services, such as traffic updates, weather, and emergency alerts.
- Advanced Features
Interactivity: ATSC 3.0 enables internet connectivity, allowing interactive content, on-demand services, and targeted advertising.
Emergency Alerts: It can deliver more detailed and personalized emergency information, including maps, evacuation routes, and specific warnings.
Customizable Content: Offers options for multilingual audio tracks, subtitles, and personalized ad experiences.
- Backward Compatibility Challenges
One downside is that ATSC 3.0 is not backward compatible with ATSC 1.0, so existing TVs with ATSC 1.0 tuners cannot directly receive ATSC 3.0 signals. Consumers will need a compatible TV or an external ATSC 3.0 tuner.
