Radio Deal Could Face Technical Difficulties

To hear officials of XM and Sirius satellite radio tell it, a merger of their companies would make almost everything bigger and better.

"The merger will allow XM to provide more programming choices for our subscribers," said Nate Davis, president and chief operating officer of District-based XM Satellite Radio Holdings. "We will be able to add popular content from Sirius to the XM lineup."

Instead of offering a one-price, all-or-nothing lineup for $12.95 a month -- as both companies do now -- they would offer smaller packages at a lower price and bigger packages at a higher price, company executives said. And shareholders would benefit, they said, because a merger would result in savings by eliminating duplications in programming, marketing and other operations.

But an examination of the companies' structures suggests that these benefits will not be easily attained, even if they persuade the Federal Communications Commission and the Justice Department to allow the merger. Both XM and New York-based Sirius Satellite Radio have huge fixed costs, mainly in multiyear, multimillion-dollar contracts for big-name talent and sports events.

On top of that, industry experts say, both firms are straining their systems' transmission capacities even before they try to add each other's content.

XM and Sirius typically drop channels when adding new ones, suggesting a filled-to-the-top transmitting system. For example, Sirius recently dropped C-SPAN Radio, a charter channel, because C-SPAN objected to being bumped off the network when Sirius wanted to air sports events.

"At any given time, we use all the spectrum" allotted to Sirius, said David Frear, the company's executive vice president. He added, however, that the number of channels can increase, depending on how the spectrum is handled.

Independent experts agree that XM and Sirius can use data compression to squeeze more channels onto their allotted spectrum -- but only to a point. The greater the data compression, the poorer the audio quality, a trade-off that cannot be pushed beyond subscribers' tolerance.

"They probably are putting about as many channels up there as they can get away with," said Ken C. Pohlmann, director of music engineering technology at the University of Miami and author of the book "Principles of Digital Audio." "They'd be total dopes if they already hadn't maxed out" their capacity, he said, because XM and Sirius have long boasted about the number of channels they carry.

The capacity question is important because the two companies have promised that no existing XM or Sirius receiver will become obsolete. That means millions of receivers, mostly in cars, must be able to receive the merged company's enhanced content for years to come. Because XM and Sirius operate on different systems, all the offerings will have to fit separately on Sirius's spectrum and on XM's spectrum.

"We'll take the XM content and feed that on the Sirius system," Mel Karmazin, chief executive of Sirius, told a congressional panel on March 7. Conversely, he said, Sirius content would be fed to XM receivers via XM satellites.

That feat will be even more challenging because Karmazin, who would run the merged company, has vowed to give listeners even more options. "Those who want to take advantage of new services, like the best of both program lineups, will be able to do so for less than this would cost today -- all with their current radio," he said in written testimony at the hearing.
