DTV around the World - Argentina’s DTV System – Technical Aspects (Part 4)

[Rodolfo]

In part 1, I offered an overall view. Part 2 covered an interview with a colleague TV engineer that is currently testing the new DTV system in Argentina (ISDB-T), with whom I collaborated over the past few years regarding how the standard was selected. Part 3 covered how the system is being implemented. This part 4 covers the technical aspects of that system, a better choice for Argentina and several other countries than the US system, although the selection was not technically guided.

Many thanks for the very useful article on DTT in Argentina.

I would like to find out some additional information on it.

Could you please let us know what is the right [b]FEC[/b],[b] guard interval[/b], [b]modulation mode[/b] and [b]frequency offset[/b]?
Finally, is Argentina using [b]SFN[/b], [b]MFN[/b], [b]both[/b]?

I suspect the right answer is 3/4, 1/8 & 1/4, 8k, +/- 125 kHz and both SFN/MFN but I would appreciate it if you could confirm this for me.

Once again, I would like to thank you for your article.
