ExpressPlay DRMI am not totally sure how this all fits together yet but back in April Intertrust and Rambus announced the following:
SUNNYVALE, Calif. — April 09, 2015 — Rambus Inc. (NASDAQ:RMBS) today announced that Intertrust® Technologies Corporation, a leading provider of trusted computing technologies, will integrate its CryptoFirewall™ advanced hardware security cores with ExpressPlay™ cloud service. This integration enables Intertrust to provide content distributors with an unprecedented level of hardware security in compatible consumer devices. Smart 4K UHD TVs are the first target devices for this integrated security solution.
Given that announcement, I found this web site which describes ExpressPlay DRM. http://www.expressplay.com/service/
After looking at that web site, ExpressPlay appears to be essentially a software based DRM service. As a consequence, this made me wonder why Intertrust would be showing interest in a silicon hardware core (CryptoFirewall)?
Then about a week ago, Intertrust issued this press release:
Sunnyvale, Calif., and Taipei, Taiwan -- July 15, 2015 - Intertrust Technologies Corporation, the inventor of Digital Rights Management (DRM), today announced that MStar, a leading global semiconductor company for display and digital home solutions, has integrated Intertrust's ExpressPlay UHD in MStar's System-on-Chips (SoC's) for 4K TVs, set-top boxes, and OTT/IP box. http://www.intertrust.com/in-the-news/?author=535aaef1e4b094b1d85e87e3
Later in that article it says this:
ExpressPlay UHD with MStar TEE provides hardware security, a trusted execution environment (TEE), and secure video paths (SVP). MStar implements Marlin on its TEE environment to provide secure boot, key protection, secure video path and HDCP2.2 functions in hardware. Together with Rambus' Cryptography Research Division, MStar also provides third-party root of trust on its SoC platform to deliver post-activation capability for all devices in the field, and is part of the MovieLabs Specifications for Enhanced Content Protection.
In my opinion, this helps fill in the picture because it shows a Rambus hardware core being targeted for high volume applications (4K TVs, set-top boxes, and OTT/IP box) working in conjunction with DRM management software. I also believe this might be part of the Vidity eco-system roll out.
In any event, I believe this is more clear evidence that CRI is transitioning from simple patent licensing (i.e. DPA, SPA, etc.), to a company that sells hardware core solutions (i.e. like ARM for example), which should be beneficial to CRI revenue growth. |
