It improves the TV viewing experience with higher audio and video quality, including up to 4K resolution, HDR, and immersive audio. ATSC 3.0 is a hybrid broadcast and IP-based delivery standard that uses OFDM modulation instead of 8VSB modulation. It supports more robust transmission for reception on both fixed and mobile devices, datacasting capabilities, and more accessibility, personalization, and interactivity.
