World's Digital OTA TV Standards: ATSC, DVB-T, ISDB-T, DTMB

--------------------------------------------------------------------------------

I would like to know what the real differences are between ATSC and DVB-T. DVB-T is the standard adopted by Europe and Asia (and perhaps other places as well?) for Digital OTA broadcasting, while ATSC is used in North America (and Japan ?)

I came back from Europe and was amazed by the number of devices now available with DVB-T tuners. Well, you have all the standard home TV Tuner add-ons (start at around $100 Cdn), but you can also find a large selection of small USB token devices (also about $100cdn or $60 or so Euros) which allow you to simply hook them up to a PC/Laptop and enjoy Digital TV anywhere.

DVB-T is also found on small portable TVs (8-10" LCD) and some DVD portable players.

The most unique thing is that reception is quite possible with a small antenna, which is maybe 6" high.

I know ATSC is mainly used here for HDTV, but it requires the same antennas as for regular NTSC OTA reception.
