What New Features Does ASTC 3.0 Provide?

Several brand-new features will be added to over-the-air TV thanks to the new ATSC 3.0 standard. Improved over-the-air TV reception and 4K HDR pictures with improved audio are the two primary characteristics that will delight cord-cutters. Channels will ultimately transition to ATSC 3.0, but it’s unclear when broadcasters will start adopting the new standard or when affordable technology will be widely accessible.

Wide color gamut, high dynamic range (HDR), and 4K resolution at up to 120 frames per second are all supported by ATSC 3.0 in terms of video. In the future, 8K broadcasts might even be commonplace. But the amount of time it will take before 4K programming becomes widely available on ATSC 3.0 channels is still unknown. ATSC 3.0 promises significant audio improvements as well.

It makes use of the most recent Dolby AC-4 audio compression technology, which enables 7.1.4 Dolby Atmos surround sound and a Voice Plus feature for improving dialogue. The atsc 3.0 tuner box is an innovative invention. A Real-Time Loudness Leveler, another volume-leveling feature of the AC-4 codec, is also included.

Can I Purchase An ATSC 3.0 TV Tuner Or Converter Box Separately?

A 3.0 tuner like the ZapperBox is commonly referred to as a “converter box” by certain individuals. That terminology is reminiscent of the digital-to-analog converter devices offered for sale when analog-to-digital TV switched over. In terms of conversion, a tuner like the ZapperBox isn’t doing anything.

Consider it a different AV device, similar to a Blu-ray player or a Roku box. The old digital-to-analog converter boxes were amazing because they were so straightforward and affordable. They let millions of people who couldn’t afford new TVs continue using their old ones. When broadcasts end, it’s too soon to say if similarly priced tuners will be readily available.

New Features of ASTC 3.0 Tuners

The main traits and specifics of ATSC 3.0 tuners are shown below:


The most recent standard for television broadcasting, ATSC 3.0, also known as Next Gen TV, provides more sophisticated features and capabilities than ATSC 1.0. To ensure ATSC 3.0 compliance, equipment, including televisions, tuners, and set-top boxes, must adhere to specific technical requirements. To receive broadcasts using the new standard, devices must include an ATSC 3.0 tuner. This tuner can demodulate and decode ATSC 3.0 signals, enabling the device to receive next-generation TV broadcasts.

High Dynamic Range Feature

These tuners are compatible with a variety of HDR formats. Such as hybrid log-gamma and perceptual quantization (PQ), which enhance the contrast, brightness, and color range of the images being displayed for a more lifelike viewing experience.

Instead of just being a function of a texture compression algorithm like ASTC, HDR support in graphics processing typically needs a larger range of capabilities inside the graphics hardware and APIs (such as DirectX or OpenGL) being used. Higher color bit depths are often used for HDR support, providing for a larger variety of brightness values and color options.

Mobile Reception

ATSC 3.0 tuners enable the mobile reception of live TV broadcasts on compatible mobile devices, such as smartphones and tablets. Customers who wish to watch TV on portable devices without using cellular data would particularly benefit from this.

Object-based audio is supported with ATSC 3.0 tuners, making it possible to enjoy three-dimensional, immersive music. When generating audio for various speaker configurations and contexts, object-based audio allows for the treatment of individual audio elements as independent objects.

Datacasting Support

Broadcasters can transmit extra data in addition to the primary broadcast signal thanks to datacasting, which is made possible by ATSC 3.0 tuners. This data may consist of broadcast-related information such as software upgrades, notifications for emergencies, extra material, and more.

The interactive capabilities supported by ATSC 3.0 tuners include video-on-demand, interactive advertising, tailored content distribution, and individualized services. These interactive programs increase audience involvement and give viewers a more personalized TV experience.

Sum Up

With the help of all of these features, ATSC 3.0 tuners may give viewers a more engaging, interactive, and customized television experience. For viewers with HDR-compatible TVs, watching television becomes more immersive and engaging thanks to ATSC 3.0’s support for HDR, which enables broadcasters to present programming with exceptional visual quality.
