Growing performance requirements and cost pressures challenges can be faced by integrating the TRANGO Hypervisor, thus allowing Set-Top Box designers and manufacturers to benefit from the breakthrough features that virtualization provides.

Example of Set Top Box architecture

Hardware Drivers can be used for hardware management services .
Trusted Services enables protection and isolation of critical code, data and key from GPL entanglements with secure memory partition.
The Software environments are independent from the communication media thus allowing:

• savings development costs for faster Time To Market
• reuse of proven software and code
• secure deployment of 3rd party services
• ease the system update by providing binary compatibility of environments

Example of a Secure Media Player using the TRANGO Hypervisor

Scenario highligths

1. Step 1: User downloads encrypted content through Linux Data connections
2. Step 2: Rights are checked by DRM agent
3. Step 3: Content is decoded into HMI VM
4. Step 4: Content is sent to LCD by HMI VM. Linux media player still has control on the flow

Benefits highlights

• Protects DRM / Broadcast keys and code
• Provides content protection against duplication and
• illegal broadcasts
• Eliminates the need for an additional security processor
• Provides isolation between proprietary code and GPLlicensed
• code such as GStreamer
• System security is independent of OS security
• Media acceleration drivers are separated
