> Just to give you a flavour of this year's event and the spin-doctors:
> Sunday kicked-off with a press conference at the 'DTV Store' (The CEA and
> NAB + ATSC created a Digital TV Store). A press conference invite with the
> tantalising phrase, "An important announcement concerning digital
> television"; definitely not to be missed. As it turned out it was merely a
> publicity stunt by the aforementioned 'gang-of-three' as an attempt to
> repair the damaged reputation of the DTV in the USA. Timed very neatly, no
> doubt, to mask the recent bad press concerning the debacle of testing
> carried out by the MSTV. Very much a self-appreciation gathering for the
> purveyors of the hype in this DTV broadcast market, the roll call of
> speakers publicly announced, and not for the first time I might add, that
> America was the 'world leader' in digital television? .

> The announcement. Ah! Yes! It was the announcement concerning this
> collaboration between NAB, ATSC and the CEA for a publicity campaign to
> drive the sales of DTV forward (This follows a recent UK and Australia
> initiative it just so happens). Gary Shapiro Chairman of the CEA tried to
> engender enthusiasm but seemed only to be convincing himself!  Once again
> he re-iterated that to date the consumer electronic market showed a boom in
> digital sales. These were announced as 648,000 devices sold so far. Don't

> offered as containing a DTV receiver. Not mentioned either is that some of
> these devices were for DVB services (HDTV on Dish Network with an 8-VSB
> tuner that is probably redundant). Lynn Claudy of the NAB in a sidebar with
> a journalist was heard to say that it depended how you were counting and
> that the figure was closer to 100,000...others still discussed the more
> realistic 25-28,000...therefore an extremely unclear scenario was laid out
> before us, once again!. Apparently the "Time for finger pointing is over",
> furthered Shapiro!  We shall see!

> Unfortunately this whole back slapping, public relations moment failed to
> address the honest fact that whilst a campaign to sell equipment of a DTV
> nature is now being undertaken at a consumer level the system that delivers
> the signals to these unsuspecting purchasers is subject to a myriad of
> RFP's in order to repair it. (It is broken! And no matter all the hype,

> Further on the trail of DTV at NAB Robert Graves the Chairman of the ATSC
