The Discretix Multi-Scheme DRM Client was demonstrated at the Mobile World Congress in Barcelona this week. It was shown running as a pre-integrated component on a phone that was also running Trolltech's Qtopia application and middleware stack for Linux phones. 6 ? E" A% n; ?. e; M* h5 R2 I7 w
Discretix says its content security technology reduces OEM time to market by ensuring pre-tested DRM protection for premium content. It supports multiple business models, including purchase, rental, and subscription, depending on the application deployed. & g) c0 k; e4 m6 h3 Q% }% l4 o3 h {* z

The client supports hardware platforms including Texas Instruments (TI) OMAP, TI OMAP-VOX, Infineon MPEH/MPEU, Renesas SH-Mobile, and NXP Nexperia. It can also integrate with hardware-based security technologies such as Texas Instruments' M-Shield or its own Discretix CryptoCell. The client can easily support new hardware platforms thanks to its thin software glue layer called the Discretix Virtual Operating System, says the company. , K' m, _5 J I: D1 C6 f ' [7 f* F# a ]!
