NEWS RealNetworks is expected to announce today that it has unlocked some of Apple Computer's most tightly held technology secrets, giving its music a way onto the popular iPod digital music player.

The announcement is part of a broader release of RealNetworks software, which will let songs sold from the company's online store play on a variety of portable devices, including the iPod and Microsoft-compatible rivals. RealNetworks has been selling songs from its digital song store since January, but the files could previously be played only on a few portable devices.

The new Harmony software, which RealNetworks said mimics the proprietary copy protection used in Apple's iTunes store, is guaranteed to be controversial. Apple has previously refused to provide licences to companies seeking iPod compatibility, and RealNetworks did not seek permission before releasing its own version of iPod-friendly software.

RealNetworks Chief Strategy Officer Richard Wolpert said: "This is actually a natural extension to a decision we made two years ago with respect to different formats. We think consumer choice is going to win out over proprietary formats."

RealNetworks' move marks a step away from what had been an increasingly confusing world of incompatible digital music formats and devices.

Record companies and consumer groups have been deeply critical of technology companies' decision to tie certain devices to specific music formats. Traditionally, CDs and DVDs have worked on any manufacturers' players, they note, while music downloads have been tied to specific brands of devices.

Indeed, several record company executives praised RealNetworks' independent steps to achieve compatibility with the iPod, even without Apple's consent.

Larry Kenswil, president of Universal Music's eLabs division, said in a statement: "Up to now, the world of downloads has been far too close to a world where the CD you buy in one store wouldn't play on the CD player you bought in another. We applaud RealNetworks' efforts to help correct this situation and appeal to all people and companies in this area to work toward a world of universal interoperability."

Apple did not return requests for comment.

Apple maintains a dominant market share in the music download business, and RealNetworks hopes that the new compatibility with the iPod will help drive customers to its online store.

RealNetworks has previously thumbed its nose at rivals in a similar way. Its 2002 Helix server, which sends media files out over the Internet, included the ability to stream Microsoft-formatted files - a capability only Microsoft servers previously had.

Last January, RealNetworks also announced that it had figured out how to let its PC software play songs purchased from Apple's iTunes store and save them onto the iPod.

The new Harmony software's ability to work with Microsoft devices is fairly straightforward. When a customer buys a song from RealNetworks' online store, the software will check what kind of portable device is attached to the computer and change the song into Microsoft's format if necessary. Microsoft has provided licenses to its Windows Media technology to many companies.

Harmony also will automatically change songs into an iPod-compatible format. But because Apple has not licensed its FairPlay copy-protection software to anyone, RealNetworks executives said its engineers had to re-create their own version in their labs in order to make the device play them back.

Although the company said this action wasn't technically "reverse engineering," the software could trigger intense legal scrutiny.

The license accompanying Apple's iPod says purchasers cannot "copy, decompile, reverse engineer, disassemble, (or) attempt to derive the source code of" the software.

Boston patent attorney Bruce Sunstein said courts have issued mixed opinions on how much reverse engineering is allowed for purposes such as making compatible products.

"The law is unsettled," Sunstein said. "We might find some litigation if Apple wanted to be aggressive."
