"Every broadcast delivered from these services can easily be stream-ripped by the public, downloaded to a user's hard drive on a song by song basis and uploaded onto iPhones and P2P networks," says MRT CEO Hank Risan. "This type of piracy is in clear violation of the performance rights granted to these distributors of copyrighted material under Section 114. MRT believes that the Librarian of Congress will exercise his fiduciary duty and put a stop to this rampant form of digital piracy by immediately revoking their licenses."

The letter says these webcasters are willfully violating their statutory internet broadcasting licenses by distributing digital content as an interactive download service and by ignoring their statutory obligations under the law. MRT says that all of the webcasters distribute digital content over systems that "avoid existing and effective technical measures designed to protect copyrighted content from unauthorized downloading, copying and re-distribution or use by recipients."

MRT claims that the webcasters incorporate or accommodate stream ripping capability within their systems and that "literally thousands of different stream ripping devices are sanctioned" by them. By transmitting copyrighted matter through such systems, the webcasters "enable the recipients of their unprotected transmitted sound recordings to select particular sound recordings that can be downloaded and converted into perfect digital phonorecords." These digital phonorecords are then capable of being used, re-distributed or re-transmitted-all without authority from the copyright owners or payment of royalties, the letter adds.

Of course, MRT makes SeCure X1, copy control technology that eliminates stream ripping and serial copying of digital content. The company wants Apple, Microsoft, Real Networks and other webcasters to implement the technology to protect American Intellectual Property. MRT claims that and that all of the devices from the above-mentioned companies "must either be immediately redesigned or removed from the market."
