Here's a column about the differences and what's coming:

I bought my current two TV sets about 6 years back. They both are capable of receiving HD Digital - and a few channels are broadcast in this format.
About two months back, one of the commercial networks started broadcasting in HD on one of its digital channels in something called "MPEG2". It also switched another of its SD digital channels over to this format. As a consequence I can only get sound on these channels and no picture as my two sets are apparently not compatible with this new process.
It is ludicrous to think (to me anyway) that a quite reasonable expenditure on a television set undertaken such a relatively short time ago, can be rendered a complete write off should all the networks decide to change over to this new process - which it is on the cards they will do so.
Now, we have even more new processes in the offing! Why? Will the signals on which they are to be broadcast be receivable by current sets?
Sure - I am not against something new coming, but I do remember that when colour signals were to be transmitted, they had to be compatible with people who still had black and white sets.
