10K Resolution at 120Hz Display: A Reality Today with DSC 1.2 in HDMI 2.1

With the arrival of HDMI 2.1 comes an array of remarkable features including the capability to support up to 10K resolutions at 120Hz. Such high resolutions are supported for a wider range of display applications such as externally connected displays (i.e. PC monitors and televisions), embedded display interfaces within mobile systems, and automotive infotainment systems. But with higher resolutions comes the requirement for higher bandwidth.

Saving Power in Displays for Mobile and Consumer Electronics Applications

Higher performance at lower power is the most critical requirement of SoC designs, specifically those targeted towards mobile and consumer electronics applications. VESA (Video Electronics Standards Association), the technical standards organization for computer display standards, came up with a new power saving feature called PSR (Panel Self Refresh) in eDP 1.3. It is also available as an optional feature in DisplayPort. PSR helps to extend battery life in mobile phones, notebooks, and tablets, and is quickly being adopted in high-end designs.

HDMI 2.1: How it Became the Most Popular Display Interface

HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards, represented using one of several luminance/color-difference color spaces. We introduced HDMI 2.1 in our previous blog – HDMI 2.1: Channeling the GenX Audio Video Experience. In this blog we will discuss about evolution and key features of HDMI from v1.4 to v2.1.

USB Type-C Alternate Mode: The One for All

In our previous blog, “Ever Wonder How USB Type-C Works”, one of the paramount features we discussed was the Type-C connector being used with third party peripherals in-addition to USB. The mode in which the Type-C cable assembly facilitates operation of “Alternate” protocols is called Alternate Mode. USB Type-C Alternate Mode specification allows MHL, DisplayPort, HDMI, and Thunderbolt over Type-C. Alternate Mode is an option made available to the USB Hosts; however, USB should be the preeminent interface to be exposed over Type-C assembly, justifying the tag ‘Alternate’.

Bernie DeLay @ EDACafe on the Value of SystemVerilog, UVM-based VIP

Here, Synopsys R&D Director, Bernie DeLay, talks to EDACafe on the value of native SystemVerilog and UVM support in our VIP titles. He describes how our memory and protocol VIP have been built debug-friendly with Protocol Analyzer, and support constraint random verification for full functional coverage with back-annotation to executable verification plans.

HDCP 2.2: Locality Check, SKE and Authentication with Repeaters

In The HDCP 2.2 Authentication Process – an Introduction, we discussed why we need HDCP, and the basic steps of the HDCP Authentication Process. We noted that an advanced version of RSA is the underlying cryptography standard used during the Authentication and Key Exchange (AKE). AKE is the first step in the authentication protocol. Here we will continue exploring the next 3 steps of the protocol: Locality Check, Session Key Exchange (SKE) and Authentication with repeater. Locality Check This is an interesting checking mechanism introduced in HDCP2.X to ensure that the receiver and the transmitter are placed nearby. It prohibits sharing of HDCP2.2 protected content over a long distance.
