Is it possible to receive digital terrestrial television (TDT) channels on a Casio TV
 

I have a Casio TV-880 portable TV and I'd like to know if it's possible to receive digital DTT channels here in Portugal. I know it's an analog TV, but I'm curious to know if it's possible to pick up digital TDT channels.

What DTT standard is used in Portugal? Is it DVB-T?
You would need a converter box that receives the DTT signal and converts it to PAL analog.
A quick search online finds converters for the U.S. systems, but I don't see any for the system used in Portugal.

The system used in Portugal is DVB-T.

I don't know if there were any DVB-T to PAL converters made. I can't find any online.
Good luck on your search.

Hi to all,
Hi @old_tv_nut, @Paulo,

I live in France, so here is the situation on the French market :

Standalone DVB-T receivers are still sold to use older televisions with today's broadcast formats, current receivers all have inbuilt tuners.

Some DVB-T standalones only have an HDMI output but many still output analog signals, switchable between PAL/NTSC and RGB on a SCART connector.
Some models only have analogue composite on 3x RCA connectors (video + stereo audio).
For a standalone with only an HDMI output, use a HDMI to PAL dongle + an analogue RF modulator (System B/G for Portugal).

Some modulators have an HDMI input direct to RF UHF output.

Here is an example of a budget DVB-T receiver with HDMI & SCART outputs :

Higher priced DVB-T receivers may include 2 tuners (watch one channel, record the other), facilities to record to a USB "Thumb Drive", and some have an inbuilt hard disk or SSD for mass storage or connection to an outboard storage device.

*caveat : depending on brand, some record in proprietary formats, others use standards such as MPEG4, H265,... useful for future editing/backup to a PC.

Hope this helps
