DTV World Standards (ATSC, DVB-T, ISDB, DMB-T/H)

E

Hi with all of the countries around the world changing to Digital televison. Will all of these standards be compatible with other standards? Unlike the analog TV, NTSC, PAL, & SECAM are not compatible with each other. Will an ATSC tv work in UK, which uses DVB-T or in Japan which uses ISDB?

No, all three of these standards are mutually incompatible - a U.S. DTV will not work in the UK or Japan and vice-versa.
 
In the same way NTSC and PAL are incompatiable with each other, all of these digital standards are the same way.

You would think in today's world there would be some effort made to unify under one world standard. Unfortunantly, the politics of the past in regards to arguing over standards are worse today, and not get any better anytime soon.
 
Of the "new" standards...which one is better?


Of the two analogues that I've seen (PAL & NTSC,) I thought that PAL actually looked better than NTSC.
 
It depends on who you ask. The two main systems COFDM and 8VSB(our system) are similar enough but each has strengths. 8VSB seems to have been chosen because TV stations are expected to cover large rural areas which 8VSB does better than COFDM. COFDM is better at handing multipath issues and locks channels better.

Each has it's pluses and minuses and depending where you are and what your needs are it could be good or bad.

One way to look at it: 8VSB is well suited for covering geographically large and generally flat areas like Dallas/Fort Worth, whereas COFDM would have an advantage covering the multipath canyons of Manhattan. Although, in fairness to 8VSB, the multipath performance of recent model tuners is pretty good when it comes to multipath, and it may be that 8VSB is now almost as good as COFDM in that respect.
