SoC designs are growing more complex, not just by the sheer number of transistors that can be packed into one design, but the emergence of different interconnect methods you must use to connect chip internals and to connect to the outside world. Becoming an expert on each of the interconnect protocols is not going to shorten the verification schedules, reduce design productivity and expose design bugs that might only be found when used by the end consumer.
Color space is a very powerful tool that comes in handy when capturing, transmitting and reproducing color back to the human eye. Systems such as cameras, GPUs, transmission cables (HDMI/DP), and monitors use color space metrics to preserve and transform color. This technology helps map real colors to the color model’s discrete values.
Lately television lovers across the world have an even better reason to be glued to the small screens, as 8K Ultra HD TVs have made their way to the market. The HDMI forums most recently released specification, v2.1, explains “higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail…” Most of us are familiar with the word “resolution”, but do we really know this term well?
The color space is a very powerful tool that comes in handy when capturing and transmitting color back to the human eye. All systems like cameras, GPUs, transmission cables (HDMI/DP), monitors, etc. use color space metrics to preserve and transform color.
HDMI (High-Definition Multimedia Interface) has been a part of our entertainment systems for nearly two decades now. Though the look of the cable has remained the same over the years, the input has undergone many improvements since its release in 2002.
HDMI ARC, What is it and Why You Should Care?
USB4 is the next generation of the Universal Serial Bus and a major update to the interface in speed and functionality. USB4 has incorporated Thunderbolt 3 capabilities, which extends support of USB interface to existing PCIE, and DisplayPort over the same USB Type-C connector. USB4 doubles the maximum overall throughput from 20Gbps to 40Gbps enabling optimized HD video and data transfer simultaneously. USB4 enables many applications using USB Type-C, which already supports power delivery, USB 3.2, USB 2.0 and other alternative protocols.
The demand for higher resolution displays is exploding across the market segments from electronics like television, monitors, laptops, and smartphones to the emerging technologies like video and vision, automotive, and AR/VR. The bandwidth requirement for displays increases multi-fold with higher resolution which has been the main driver for development of the latest DisplayPort 2.0 specification by VESA.
High resolution 8k UHD displays for emerging technologies like connected cars, IoT, and AR/VR (Augmented/Virtual Reality) require high bandwidth to support the high-resolution transmission. MIPI DSI is the widely used display interface, but the bandwidth provided by PHY layers isn’t sufficient enough to support the high-resolution displays; therefore, a compression technique like DSC (Display Stream Compression) is required. One of our recent blog discussed about DSC 1.2 in HDMI 2.1 – High Resolution Displays for Mobile, TV, PC and Automotive Enabled by DSC 1.2 in HDMI 2.1. In this blog, we will see how DSC 1.2 enables MIPI DSI to support the high-resolution displays for emerging applications.
The latest buzzword in the world of TVs and smartphones is High Dynamic Range (HDR). Many of us might already know that an HDR TV improves the viewing experience by offering better picture quality, just like people who use the latest smartphones know that turning on the HDR mode in the camera helps in capturing more lively pictures. In November 2017, the HDMI forum officially released HDMI 2.1 adding more to our joy, by offering the new and improved HDR. The announcement goes on to say “Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis”. Before we explore HDR and Dynamic HDR in detail, let’s first understand how Standard Dynamic Range (SDR) works.
