Smarter Than A Card

Set-top boxes (STBs) were initially secured by Conditional Access System (CAS) smart cards. However, this approach is no longer effective. Smart cards cannot prevent unauthorized access to premium 4K and UHD content, as they are not designed to protect the interface between the card and box, or the STB SoC itself. This is one of the reasons why cardless CAS set-top boxes, equipped with a hardwa... » read more

Bringing a Sharper World In Focus With Virtual UHD Verification

UHD-4K designs require a verification solution that can handle longer, larger frames, faster frame rates, richer colors, wider contrasts, and highly complex chips. Emulation has the speed, capacity, and performance to churn very quickly through the massive amounts of data and long sequences required for verification. Visualization tools are needed to understand and debug what’s going on in UH... » read more

HDMI 2.0 Design And Verification Challenges

High-Definition Multimedia Interface (HDMI) is an audio/video (A/V) transmission protocol, which is omnipresent in consumer electronics, personal computing, and mobile products. Modern-day requirements of big screen resolutions, 3D, and multi-channel/multi-stream audio have pushed display devices to use a completely digital, high-speed transmission media, requiring a multi-layered protocol like... » read more
