Featured Case Study: RTL Tele Letzebuerg
To coincide with our participation in NAB 2018, this week’s featured case study is an excellent installation of fine pitch Leyard® TVH Series LED Video Walls at RTL Télé Letzebuerg’s new broadcast facility in Luxembourg. The remarkable facility includes multiple soundproof radio and sound studios as well as new state-of-the-art television studios. Along with other cutting-edge technical equipment, two video walls of fine pitch Leyard TVH 1.6mm pixel pitch LED, one 12.8 x 1.8 meters and one 2.0 x 1.8 meters, were integrated to be used as backdrops for multiple daily programmes. You can see for yourself, they look great and the whole studio has a very More…
DisplayPort 1.4 vs HDMI 2.1
A closer look at both DisplayPort 1.4 spec, and the newly ratified HDMI 2.1 spec to see the difference between them Both HDMI and DisplayPort can send high-definition digital video and audio from a source device to a display. Each format has had various updates and versions over time, but with the introduction of HDMI 2.1, it’s a good time to provide an update on the current standards involved in both. We will be taking a closer look at both DisplayPort 1.4 spec, and the newly ratified HDMI 2.1 spec to see the difference between them. The HDMI (High Definition Multimedia Interface) specification was conceived over 10 years ago by a consortium of More…
What is Pixel Pitch and Why Does It Matter?
What is pixel pitch? Pixel pitch describes the density of the pixels (LED clusters) on an LED display and correlates with resolution. Sometimes referred to as pitch or dot pitch, the pixel pitch is the distance in millimeters from the center of a pixel to the center of the adjacent pixel. Since pixel pitch indicates the amount of space between two pixels, a smaller pixel pitch means there is less empty space between pixels. This equates to higher pixel density and improved screen resolution. Key Takeaways: Pixel pitch refers to the density of pixels A smaller pixel pitch indicates higher pixel density and higher resolution Pixel pitch is More…
Featured Case Study: Chicago Cubs Team Store
Built in 1914, and inhabited by the Chicago Cubs since 1916, Wrigley Field is one of the most historic sports venues in the United States. It’s the second oldest ballpark in the MLB (after Fenway Park, 2012), and was the last to have stadium lighting installed. The Cubs also have a rich history. Founded in 1876 as the White Stockings, they became the Cubs in 1903 and became the first MLB team to win the World Series twice in 1907 and 1908. What followed, however, was the longest championship drought in all major North American sports. It’s fitting, then, that the Cubs would finally win another championship in 2016, their 100th year in Wrigley More…
What do integrators need to know about 4k content playback?
The amount of 4K video content available to be viewed remains relatively low. Netflix and Amazon Prime are currently the two best streaming sources, though the recent release of UHD Blu-ray opens the door for many more titles to become available in 4K. TV broadcasts in 4K are scheduled to start later this year. In the non-consumer world, PC applications dominate as content providers for 4K displays, as video graphics cards have supported 4k output for quite some time. 4K content requires substantially higher data rates than 1080p content. As a result, the existing H.264 / AVC compression algorithm traditionally used on various 1080p content simply More…
What do integrators need to know about wide color gamut displays and content?
Distinguishing WCG from non-WCG The color gamut of a display is usually quantified in terms of the NTSC standard created in 1953. Most LCD displays on the market today are designed to meet the HDTV color gamut standard, known as Rec. 709 (or alternatively BT.709). Compared to the NTSC standard, the Rec. 709 color gamut covers roughly 72% of the NTSC color gamut. In display circles, we refer to the color gamut of a display using this percentage NTSC measurement, such as “72% NTSC,” which is the most common specification for LCD displays on the market. While there’s no formal definition for wide color gamut (WCG), anything above 72% NTSC is generally More…
What do integrators need to know about color subsampling?
In order to reduce the bandwidth necessary to transmit 4K content, the new HDMI 2.0 specification includes support for 4:2:0 subsampling. This reduces the color information in the signal by 75%, leading to a 50% reduction in bandwidth. Much of the video content currently available is already 4:2:0 subsampled, so there won’t be any additional degradation of the image as a result of the subsampling. However, in other content, such as PC graphics inputs, 4:2:0 subsampling can introduce significant image artifacts. This is especially noticeable in text. When selecting a product with 4K @ 60Hz support, integrators should be checking what color subsampling More…
8K Connectivity
Demand for high resolution across all displays is on the rise, explaining why industry attention today has moved beyond HD to 4K and Ultra HD displays with sights set on the 8K ecosystem ahead. So why not just add 4 times the pixels of Ultra HD call it a day? Unfortunately, the high data rate required for connectivity makes 8K resolution more complicated than simply adding pixels. Consider an 8K image may: display up to 120 frames per second (fps) require a minimum of 10 bit color require the color sub-sampling 4:4:4, 4:2:2, or 4:2:0 One common example of this is an RGB signal with 8K pixels, 10 bits of color, 4:2:0 color sub-sampling, and More…
What do integrators need to know about HDCP 2.2?
Adding to the alphabet soup that is display specifications, HDCP stands for “High-bandwidth Digital Content Protection.” It was first developed by the Intel Corporation and is now ubiquitous across consumer video sources and displays as a way to protect copyrighted materials from privacy. According to the license holders at Digital Connection, HDCP “eliminates the possibility of intercepting digital data midstream between the source and the display” (like directing it to a recording device). It was first introduced for DVI in 2000 and has since gone through several iterations over the years. Each to support a broader range of devices and to overcome More…News and Events
