Broadcast digital TV will enjoy the televisions viewers in major cities of the world, Washington receive digital TV signals via satellite broadcast and receive information from foreign media, in the estimated large cities of the world will also be easy to get digital TV signals.
Digital TV users will have increased dramatically in the input and will eliminate the conventional television, especially in some developed countries.
The switch to digital TV has caused static and headaches for thousands of viewers in the Washington region. But for one local station, the transition has been something of a revival.
MHz Networks, based in Falls Church, has carved out a niche for international programming over the past 15 years,
showing Russian newscasts, Nigerian documentaries and Italian mysteries, to name a few of its offerings. To build its digital antenna and boost the signal's power, MHz shut off analog to its two channels in September -- the first station in the country to do so -- leaving many viewers who were not yet equipped to receive digital signals believing it had simply disappearead.
But on june 12, when viewers hooked up converter boxes and scanned for digital stations, MHz came through at full strength.
"We got calls from people all over saying, 'You're back!' " said chief executif Frederick Thomas, who
started working at the public television station 15 years ago as a programing manager.
MHz Networks is owned by Richmond-based Commonwealth Public Broadcasting and, through Affiliate agreements with broadcaster and cable and satellite companies, reaches 27 million households across the country.
But viewers in the Washington region and some in Baltimore, now get to watch 10 channels over the air free of charge. (The digital transition gave the network eight extra channels to broadcast additional foreign content.)
Five channels, including programs from the Middle East, China and Japan, are aired from a 698-foot tower in Falls Church, while the remaining five channels with programs from Vietnam, France and South Africa are aired from a tower in Prince William county. (Viewers have to point
their antennas in that direction to receive the channels.)
