United States. According to Mark Aitken, vice president of the Sinclair Broadcast group and president of ATSC TSG/S4 group responsible for the standardization of mobile digital television in the United States, a new standard for the transmission of digital television signal will emerge within three years.
For an industry that barely completed the transition of DTV stations in mid-June, this announcement might sound extreme, however, Aitken assures that although this transition is fresh it does not mean that it is a new technology, "the most important elements of the VSB standard, for example, are almost 20 years old, that is, today we are living a vision of 20 years ago".
The specialist delivered a study on the future direction of transmission in the U.S. The U.S. Conference & Exhibition is expected to deploy a "heteronet," a heterogeneous digital television transition network that overlaps wireless infrastructure to harness the power of television, wireless internet, and cellular networks, i.e., interactivity.
Aitken explains that mobile DTV receivers are equipped with long equalizers and decoders that are based on short equalizers, as a result, adding repeater channels and other similar approaches "this type of mechanism serves for mobiles, it does not work for fixed reception," says Aitken.
In the opinion of the specialist, a new digital television standard designed to fulfill the function of overlap, will not only overcome this problem, but will offer wireless operators an important reason for the transition with competing spectrum for the broadcasting of allies and commercial partners.
