A tiny DAB didn't do it in Canada

A little DAB didn't do it in Canada
Apparently believing the aged Brylcreem marketing slogan "A Tiny Dab'll Do Ya," Canadian proponents of the digital audio broadcasting (DAB Radio) engineering relied on a couple of stations in significant markets across the country to spread the word.
It didn't function.

The Canadian Broadcast Corp. That's possibly a great point.


DAB Radio is the 30-year-aged European technologies that very first aired as a BBC broadcast in the mid-1990s.
It was the initial to use the orthogonal frequency division multiplexing modulation method that has grow to be something of a regular option for wideband digital methods.
Rather than tuning to an AM or FM frequency, a listener can access stations on both frequencies via DAB Radio.

But the engineering has difficulties.

Furthermore, DAB Radio's signal delay of 2 seconds can be discombobulating to a listener who also is watching an event on a Television.


Canada's DAB Radio experiment ran into other difficulties.
Simply because the 73 DAB Radio stereo stations in the nation are located in major markets, rural locations in in between - and there are lots of rural areas in Canada - have been under-served. This also roiled automakers whose vehicles could not pick up strong electronic signals in between metropolitan areas. Carmakers opted for satellite stereo instead.

Furthermore, most Canadian electronic stereo utilizes L-band for broadcasting, but dominant European programming on DAB Radio is on Band III at the opposite end of the MHz dial. Finally, because dual-language Canada needs digital receivers to accommodate both French and English, stereo manufacturers had to create units just for a Canadian marketplace, which was not a lucrative enterprise program.

The apparent failure of DAB Radio to take maintain in Canada most likely opens the door for an in-band, on-channel (IBOC) electronic takeover.
IBOC is the method adopted in this nation by the Federal Communications Commission, presently in the form of HD Radio, the iBiquity Digital Corporation's leading entry in the electronic sweepstakes.


IBOC's large edge is that digital and analog radio signals can be broadcast simultaneously on the exact same frequency. This indicates radio listeners can get by with their present receivers. In Canada, this indicates cars traveling among cities will be ready to receive digital programming. But IBOC isn't a perfect system either.
Because it pushes a little beyond the edge of a channel's authorized frequency, interference with nearby station broadcasts occasionally happens. So, remain tuned, particularly if you are in Canada.
Your broadcast alternatives are evolving correct just before your ears.
