Geniatech A683 is an ATSC 3.0 USB TV Tuner

ATSC (Advanced Television Systems Committee) is the standard used in North American, and some other countries around the world such as South Korea, for digital terrestrial television that allows you to receive free-to-air or paid channels over an indoor or outdoor antenna. ATSC 3.0 is the very latest version of the standard with new features including “H.265/HEVC for video channels of up to 2160p 4K resolution at 120 frames per second, wide color gamut, high dynamic range, Dolby AC-4 and MPEG-H 3D Audio, datacasting capabilities, and more robust mobile television support” (Source: Wikipedia).

The first deployments occurred in South Korea in May 2017, but it’s unclear where the US is at the moment, and it seems there were some broadcast tests in 2018, but not full deployments. Nevertheless, if you want to watch or record programs in ATSC 3.0 channels, you’ll need new hardware, and currently most TVs won’t ship with an ATSC 3.0 tuner, so an easier way is to use USB adapters and Geniatech has just announced A683 ATSC 3.0 USB TV Tuner.

  1. The USA is proceedings with roll out. The two TV standards will run side by side for years after introduction, in USA.

    Also yesterday I was reading of working in another country combining Atsc and 5G. Future looks interesting.
    “. Korean cellco SK Telecom, together with Sinclair Broadcast Group and Harman International Industries, has successfully demonstrated next-generation TV broadcasting by combining ATSC 3.0-based broadcast network and SK Telecom’s 5G network. “

    1. I also saw the US submitted ATSC 3.0 to the ITU to make it an international standard. This made me laugh, as it’s not going to happen, and I did not mention it here either.

      1. We are in times of change for sure.
        UK freeview frequencies have been squeezed to give room to mobile phone. In America satellite frequencies are being cleared for 5G mobile phone ( cellphones ).
        While OTT, SVOD, VOD grow, yet you have pay for broadband on top of the service cost. The TV , Sport and Film delivery services sure are experiencing change.

      2. By definition it is international by being used in multiple countries (US, South Korea, Canada). Which is different from being a worldwide standard.

        But yeah, not supporting hevc send ridiculous for something supposedly supporting atsc 3.0.

        Without it it’s just 2.0, isn’t it?

        1. Sorry, my wording was not accurate enough. That’s what the proposal is:

          The United States of America has proposed to the International Telecommunication Union (ITU) adoption of the ATSC 3.0 digital broadcast standard for use by all countries in the world. The proposal is the first major step in the evaluation process for worldwide acceptance of the standard.

  2. Hopefully this is just another typo in the specs – but it lists the input as 8-VSB
    In the US – the signal will be OFDM modulation (more like the rest of the world) so I hope they have the correct modulator inside!
