No, the Ematic AT103B is an over-the-air digital ATSC tuner and will also can convert the digital signal to analog NTSC for older TV tuners. It will not work with any cable service and is for "cord-cutters". The AT103B requires an antenna to receive your local OTA channels. Depending on where you live, you may get some channels with an indoor antenna. You will get better reception with an outdoor antenna. See http://www.tvfool.com or http://www.antennaweb.org for details on the channels you can receive with an antenna pointed in a particular direction.
The Ematic set top box does provide an HD signal output and a DVR (time-shift function) so it is more advanced than the first generation OTA converter boxes. The original (available with the government coupon) converter boxes only gave an SD output.
I hope this helps.

(antennaweb.org gives a very conservative list of available channels but assumes an external antenna. tvfool.com lists the channels that are likely to be received with a variety of antenna strengths. An antenna signal amplifier can improve the reception. (Digital stations will not be seen if the tuner can't lock onto the signal.) However, when the amplifier fails, you may find some channels will not be received at all.)
Testimonial: "Thanks for your info. I ordered this converter and never saw the antenna requirements until I received it and was reading the manual! Thanks for help."

actually this ematic digital converter box can be used with cable service. it has a feature called pass through. a quick google search will explain. i have this box.
I think you are dead wrong! I have an eMatic AT103B and it IS NOT AN ATSC BOX! It's convertible only between NTSC and PAL. NTSC= USA, PAL= EUROPE. Nothing else that's it. You're spreading false information.
