ATSC 3.0 Advantages

ZapperBox brings all the features of ATSC 3.0 to your TV - 4K resolution, High Dynamic Range picture quality, and Dolby® AC 4 audio.


4K

ZapperBox M1 supports 4K TV displays. 4K is also known as ultra-high definition or UHD. A regular high definition screen has 1920x1080 or over 2 million pixels. A 4K screen has four times more pixels or nearly 8.3 million pixels. The screen resolution is usually 3,840x2160 pixels.

HDR

ZapperBox M1 supports HDR TV displays. This requires support for HDCP version 2.2 or higher. HDR is an acronym for High Dynamic Range Imaging. It is one of the primary benefits of some newer Ultra High Definition TVs and the new ATSC 3.0 standard. HDR extends the contrast and color range encoded in the transmission as well as the capabilities of the TV display. In a TV set HDR works primarily by turning off the LED colors not required behind portions of the TV display. HDR is also a green technology because it reduces the power consumption of a display by around 50%. Many side-by-side comparison tests of HDR vs 4K UHD have shown that HDR enhances the picture quality even more than 4K UHD video does. ATSC 3.0 provides the benefits of both HDR and 4K UHD.

Dolby® AC 4 Audio

ZapperBox M1 supports Dolby® AC-4 as required by the ATSC 3.0 standards. AC-4 is the new audio standard that has been approved for new DVB and ATSC standards. It offers improvements like support for multiple audio tracks, loudness management, better audio/video frame alignment and a 50% reduction in bit rate compared to Dolby® Digital Plus. Dolby® AC-4 is extensible and allows for new features to be added to Dolby® AC-4 while maintaining compatibility with older decoders. Dolby® is a registered trademark of Dolby Laboratories.
