How do I know if myTV receives a digital signal?

Do these digital boxes connect via an analogue tv cable and add more channels than those currently showing on analogue,and allow us to watch more tv channels ? If so what is the best digital box to get so as to watch English speaking channels either free or by subscription.

That's a bit of a question.

The intent of the DVB-T2 set top boxes is to allow Thais that currently receive their TV programming over the air via antenna, to continue to have access to over-the-air programming even though the analogue transmissions are being converted to digital. The DVB-T2 set top box becomes their new tuner. It's not meant to be connected to a Cable system (**see: to add a bit of complication).

As many Thais still have TV sets with "Analog tuners", or alternate "Composite Video, L/R stereo audio input", most of the DVB-T2 set top box tuners are designed to function with this LEGACY type of input, by either converting the output to RF Channel 2/3 or SD Video / Stereo Audio.

The DVB-T2 set top box can also have multi-wire "Component" or "HDMI" interface for sending the received signal direct to the TV in original format.

If you already have a TV with a built-in DVB-T2 digital tuner then you don't need the external set top box.

As the TVB-T2 set top box is just an external 'tuner' used to select one of many possible digital channels and send it, or convert and send it, to a TV ... it really can't be said to be adding more channels to those already available via analogue TV Cable. It's just a tuner box, like using a Satellite TV set top box.

These DVB-T2 set top boxes are very similar to DVB-S2 satellite set top boxes, and in fact do the same thing. But they pick up terrestrial-sent signals rather than satellite-sent signals.

To add a bit of complication into this answer... large buildings will sometimes use a Analog or Digital Cable redistribution system to deliver TV content to building occupants. The system can be Analogue-based --where the distribution system individually used a set-top-box or tuner to receive each channel input from various sources (like analogue or digital terrestrial TV signals, Cable or Satellite TV content) and assigns it to an analogue channel on their internal system. Or the system can be Digitally based --where they take in a 'block' of raw Digital signals like those available from a Terrestrial Digital Antenna or constellation of Satellite Dishes and allows the occupants set top box to select the appropriate 'block feed' and tune the channel directly, as if the Antenna or Satellite Dish only belonged to them (allowing each occupant to have unique subscription opportunities with satellite providers).

The TV channels available over terrestrial digital will most likely be the same basic and local Thai-language broadcast channels that are Free-to-View / Free-to-Air that are also available over satellite. Very unlikely Thai terrestrial digital TV would ever be used for subscription content.

Unlikely there will be many English-language content (outside of learning programs). But we haven't received much in the way of first-hand reports.

There are a few more channels with the digital box than with analogue signals. No real 100% english channels but now nearly all channels have dual audio capability so that if there are UK or USA shows then the english soundtrack can be selected. At least i can do this with my samsung tv not sure if all of the digital boxes will let you do this.
