In the recent Caper 2004 it was converted, as every year (since 1998), to deal with the subject of TV digital.
Although over the years the issue was attenuated, we are surprised by the presence of the ATSC Forum in a country like Argentina, where the standard has already been chosen (October 1998), and which apparently enjoys the sympathy of the most important broadcasters.
The drivers of the standard, a On an international scale, they should focus their efforts on Brazil, which has demonstrated, since February 2000, its non-conformity with 8VSB modulation, today improved in the called enhanced 8VSB. But ATSC has made huge efforts to improve its standard, and thus safeguard itself from the criticism that, at the time, he had even in his country of origin.
ATSC representatives have stated that with the fifth generation of receivers, the multipath problems, were satisfactorily resolved.
In the United States there are more than 1400 digital TV stations, covering 99.7% of households with receptor. In this country there are 70 million cable subscribers, 18 million to satellite reception and 18 million viewers by air exclusively.
Then, the doubt of whether the air standard (ATSC) will be mostly received by the cable subscriber. We know that in the satellite the norm is DVB.
While other countries wait adopt the standard, only five have ATSC: United States, Canada, South Korea, Argentina and Mexico (which adopted it on July 2 past).
The conferences of the representatives of the digital TV commission of the Argentine Center of Engineers, CAI, referred tepidly to the benefits of the new technology, given the limited time allotted; Highlighted above all, the expression of the engineer Osvaldo Parodi, when said that Argentina still has a deficit of analog TV, and it seems premature to get ahead of thinking about transmissions Digital.
The landscape for the ATSC standard indicates that most Latin American countries are studying and possibly adopting it, but it cannot be stated in what a moment.
As an interesting fact, in Mexico evaluate to finish the transmission stage, that is, the shutdown of the analog, only for the year 2021.
On the side of broadcasters, HD productions began to be made, and this was the moment to announce it, also lukewarmly, making clear the economic prudence with which this new technology is faced.
A weekly program has already been broadcast, generated in high definition, which transmits channel 13 and which someone has questioned about its high compression.
Anyway, it was not clear how many receivers were capable of obtaining digital signal on channel 12, within the framework of the coverage of the ad-hoc transmitter.
To resolve this and other doubts we can only wait for the next Caper 2005.
