NAB2025 was not what I expected. The biggest thing I noticed was lack of hardware. Cloud and NDI were everywhere. In fact, it was the year of NDI. The big legacy hardware vendors all had an NDI offering at various stages of development. “NDI compatible“ signs were everywhere. Everyone is asking for less upfront cost, more flexibility. You can’t always do that with traditional hardware. Even the big boys (think 3 and 4 letter networks) are adopting cloud. #cloudproduction #controlroom #cloudflex

Welcome to my cheesy analogy mixed with a little tech geek thrown in! Recently I was on set explaining monitor calibration and color bars to a client and a PA. Somewhere between chroma values and broadcast standards, it clicked...If the monitors aren’t calibrated, you might be watching the same thing but interpreting different realities. One person sees contrast, another sees noise, another thinks it’s “fine.” Alignment doesn’t happen by accident. It’s engineered, crafted and takes a little time! Teams work the same way. You can give everyone the same goal, the same tools, even the same timeline, but without calibration, the output drifts. Language, expectations, standards, and intent all need tuning so the signal stays clean from start to finish. That’s how you get congruent results instead of creative static. We tell stories. We capture moments. We create content. We curate experiences. And yes, we’re technicians, because great results come from both art and calibration. Now...for anyone that really wanted some of the technical stuff...keep reading. Color bars are video test patterns used to calibrate display color accuracy, brightness, and contrast. The primary differences lie in saturation levels (100% vs. 75%), the inclusion of specialized calibration elements (like PLUGE for black levels), and their intended application (broadcast, consumer, or HDR, with SMPTE bars being the most common standard. Key Types of Color Bar Patterns: 75% Color Bars (Standard/SMPTE): The most common, representing 75% intensity, used for calibrating color (chroma) and tint. They include a PLUGE (Picture Lineup Generating Equipment) pattern in the lower-right, which helps set proper black levels. 100% Color Bars: Used for more intense color decoding, testing if a display can handle full-luminance colors without clipping. These are generally used in production environments rather than consumer TV calibration. SMPTE Engineering Guideline (EG) 1-1990: The standard, multi-component pattern featuring 75% bars, PLUGE for black levels, and white/blue squares to adjust color and tint using a blue-only mode. HDR/WCG Color Bars: Specialized bars that handle higher dynamic range and wider color gamuts, essential for calibrating modern displays. Gray Bars (8 or 16 Step): While not color bars, these are often included alongside them to adjust grayscale tracking, gamma, and brightness/ contrast. Key Differences in Usage: 75% vS 100%: 75% bars are standard, ensuring colors are not overly saturated for traditional broadcasting. 100% bars are used to test the maximum capabilities of a display. SMPTE vS Basic Bars: SMPTE includes extra, specific, and "sub-black" elements (PLUGE) that enable precise, quick calibration ot brightness, contrast, and color, which a simple 8-color row cannot do. Looking forward to your comments!)

ATSC (B2X) Multicast Broadcast Neutral-Host O-RAN System Architecture First paper to be published IBC 2025 https://lnkd.in/eRyCBMza ABSTRACT ATSC 3.0 is the most advanced digital broadcast standard. This paper introduces Broadcast-to-Everything (B2X), a new physical layer Radio Access Network (RAN) standard being developed by ATSC. B2X enables multiple users to share multiple radio frequency (RF) carriers in various IMT and broadcast bands (ranging from 5 MHz to 50 MHz). B2X is optimized for battery-powered devices. B2X builds on ATSC 3.0's Layer 1 (L1) and Layer 2 (L2) protocols where applicable and includes new L1/L2 control signalling. It operates within a Neutral-Host shared Open RAN (O-RAN) system, supporting a variety of services such as wearables, IoT, and Smart City applications with flexible Fast Fourier Transform (FFT) sizes of 128, 256, 512, and 1024. To ensure reliable and scalable performance, Orthogonal Frequency Division Multiple Access (OFDMA) is used, breaking the physical layer into Physical Resource Blocks (PRBs), each containing 24 subcarriers spaced 3 kHz apart. A scheduler allocates PRBs based on service needs, with Virtual Bandwidth Parts (VBP) assigned to each application. B2X is designed for efficient multicast and broadcast with carrier aggregation to increase capacity. It enhances mobile performance using intelligent Single Frequency Network (SFN) topologies, allowing content delivery over a wide-area SFN or cloud-based edge networks. For 5G/6G interworking and traffic offloading, B2X uses the O-RAN F1 interface to encapsulate the 5G/6G-PDCP (Packet Data Convergence Protocol) layer 2. The data is transmitted via B2X baseband over O-RAN fronthaul to SFN transmitter sites for emission. Dual-connected user equipment (UE/UBE (User Broadcast Equipment)) retrieves and passes the PDCP layer 2 to the 5G/6G UE PDCP buffer, completing the offload process.
