TV Tuner - ATSC 3.0, DVB, ISDB

What is an ATSC 3.0 tuner?

ATSC 3.0 tuner, also known as next gen TV tuner, refers to a type of tuner designed to receive broadcasts using the ATSC 3.0 standard.  Compared with ATSC 1.0, ATSC 3.0 brings several advancements, including better video and audio quality, support for higher resolutions such as 4K Ultra HD, improved reception for mobile devices, targeted advertising capabilities, and interactive features.

Is a 3.0 ATSC signal stronger?

ATSC 3.0 signals are not inherently stronger than ATSC 1.0 signals in terms of power output. However, ATSC 3.0 offers improvements in robustness and efficiency in signal transmission, which can result in better reception quality and coverage compared to ATSC 1.0 under certain conditions.

How does an ATSC tuner work?

An ATSC tuner works by capturing digital television signals through an antenna, demodulating the received signals to extract digital data, decoding this data to interpret video, audio, and other information, and finally outputting the decoded signals to a television or display device for playback, enabling users to access over-the-air digital television channels without a subscription.

Does ATSC support 4K?

ATSC supports 4K Ultra HD resolution. The latest iteration of the standard, ATSC 3.0, enables the transmission of content in 4K resolution, also referred to as 2160p. This advancement empowers broadcasters to deliver high-definition television content with notably higher resolution and enhanced picture quality compared to standard high-definition (HD) broadcasts. Viewers can experience 4K content over-the-air through ATSC 3.0, provided their television sets or devices are equipped with compatible ATSC 3.0 tuners.

Does ATSC support 1080p?

ATSC, the Advanced Television Systems Committee, serves as the standard for digital television transmission across terrestrial, cable, and satellite networks in the United States and elsewhere. Within the ATSC framework, various resolutions are supported, encompassing 1080i (interlaced) and 1080p (progressive scan), alongside other formats like 720p and 480i/p. Consequently, broadcasters have the flexibility to transmit content in 1080p resolution should they opt to do so, given the adaptable nature of the ATSC standard.

What is the difference between NTSC and ATSC?

NTSC and ATSC are both standards used for television broadcasting, but they differ in several key aspects:

• Technology: NTSC, an analog TV system prevalent in North America and parts of South America, has been succeeded by ATSC, a digital TV standard developed to enhance audiovisual quality. ATSC supports multiple resolutions and aspect ratios.
• Signal Type: NTSC employs analog signals prone to degradation over distance and in adverse weather. In contrast, ATSC utilizes digital signals, less prone to degradation, ensuring superior picture and sound quality.
• Resolution: NTSC generally offers lower resolutions like standard definition (480i), while ATSC provides a broader range, encompassing standard definition (480i), high definition (720p, 1080i), and even ultra-high definition (4K) based on broadcaster and viewer equipment capabilities.
• Compatibility: NTSC-compatible equipment is not directly compatible with ATSC signals, and vice versa. Viewers typically need compatible televisions or set-top boxes to receive and decode the respective signals.
• Aspect Ratio: NTSC typically employs a 4:3 aspect ratio, suited for older CRT televisions, whereas ATSC accommodates a broader spectrum, encompassing both traditional 4:3 and widescreen 16:9 formats, better tailored for modern digital displays.
