Macrovision Corp. has released an updated version of its copy-protection technology that allows for limited burning and transferring of secure CD files.

Macrovision VP of music marketing Adam Sexton says the company hopes to have usage rights for copy-protected tracks similar to those offered on secure pay-per-downloads through iTunes and other services.

Macrovision's technology previously allowed for playback of music on a PC but blocked ripping and burning of tracks.

Copy-protected discs featuring the new technology are expected to hit the market in Europe and possibly Asia in the second quarter.

U.S. adoption of copy-protection technology remains limited. Macrovision, and rivals like SunnComm Technologies, are hoping that the development of "second session" technology--which allows CDs to hold secure files that can be copied and moved to portable devices-will lead to greater acceptance from U.S. labels.
