A brief history of TV audio: from mono to stereo, then digital TV with compressed data and wider bandwidth. Digital audio supports up to 5.1 channels but requires bit rate reduction. Lossy codecs discard inaudible information using masking curves. Dolby Digital frames consist of 1,536 audio samples. Next-generation audio (NGA) supports immersive, personalized audio and enhanced dialogue. Adopted by ATSC 3.0, DVB, ISDB, cable, satellite, and TV 3.0 in Brazil. NGA enables new features and improved audio experiences. #TVaudio #DigitalAudio #DolbyAtmos #NextGenAudio #ATSC3 #AudioTechnology

Not so super Frank C. seems to never get the facts straight. Let''s take the time to review his latest 'drivel' 🧱 FACT CHECK: Setting the Record Straight on “5G Broadcast vs ATSC 3.0” 1️⃣ “5G Broadcast is advancing globally while ATSC 3.0 struggles.” ❌False. ATSC 3.0 is deployed in more countries and more receiver types than 5G Broadcast. Fact: ATSC 3.0 is on-air across the U.S., South Korea, Jamaica, and Brazil (TV 3.0), with additional trials in Canada, India, Mexico, and multiple European markets. Meanwhile, there are no nationwide 5G Broadcast deployments anywhere—only isolated MNO pilots in Germany, Austria, and China. 2️⃣ “ATSC 3.0 can’t be received on phones.” ❌Completely outdated. Fact: ATSC 3.0 reception is active on feature phones, smartphones, tablets, USB-C dongles, gateways, and TVs from multiple vendors. The ecosystem includes Saankhya/Tejas, MediaTek, SiliconDust, and others—commercial hardware, not prototypes. 3️⃣ “5G Broadcast is the only global standard (3GPP).” ❌ Misleading. Fact: ATSC 3.0 is an ITU-recognized international broadcast standard (BT.2037, BT.1877)—same global recognition level as DVB-T2 or ISDB-T. ATSC 3.0 is also natively IP, fully interoperable with 3GPP systems (that’s the foundation of B2X – Broadcast-to-Everything). 4️⃣ “Release 18 feMBMS is a game-changer.” ❌Hardly. Fact: Release 18 adds incremental improvements—larger guard intervals, extended SFN support, and optional return path—but it remains dependent on operator spectrum and core integration. ATSC 3.0 already exceeds feMBMS throughput, spectral efficiency, and modulation flexibility, operating independently in broadcast bands and enabling one-to-many delivery without network load. 5️⃣ “Brazil will also implement 5G Broadcast to complement TV 3.0.” ❌ Blatantly false. Fact: Brazil’s SBTVD Forum explicitly rejected 5G Broadcast for terrestrial TV services. TV 3.0 is based on ATSC 3.0 physical layer technology. The separate MNO-led study on mobile use cases is not part of TV 3.0 and has no official adoption. 6️⃣ “India is aligning with 5G Broadcast.” ❌ Misrepresented. Fact: India’s D2M (Direct-to-Mobile) initiative is ATSC 3.0-centric, jointly developed by Prasar Bharati, IIT Kanpur, and Saankhya Labs. Government agencies recognize ATSC 3.0 as the technical basis for large-scale D2M deployment. 7️⃣ “ATSC 3.0 is its own worst enemy.” ❌Wrong again. Fact: ATSC 3.0 is the only broadcast system proven to deliver UHD, HDR, datacasting, emergency alerts, and IP services at scale—while converging with telecom and satellite systems in real deployments. The global momentum speaks for itself—ATSC 3.0 is the broadcast foundation for the connected world. 🔧 Bottom Line feMBMS is a network feature. ATSC 3.0 is a full system. ATSC 3.0 delivers broadcast-grade performance today—independent, interoperable, and global. The world isn’t “swimming against the current.” It’s following the current—and that current flows through ATSC 3.0.

Another disguised AI miss “Broadcom’s Earnings: Singing ‘Deck the Halls’ While The Data Sings 'Not Like AI Boom At All' “…Broadcom is now one of the most systemically important companies in global markets. And beneath the festive cheer of the AI narrative, the valuations tell a much colder story….. It’s the financial equivalent of watching customers flood into a store, fill their carts, walk up to the checkout counter… and then leave without paying. The aisles look busy, the shelves look empty, the activity looks real—until you open the register and realize it barely moved. That’s Broadcom this quarter. Revenue is rising, receivables are ballooning, and cash flow is falling behind both—clear evidence that the company is booking demand, not monetizing it. This isn’t what the start of an AI supercycle looks like. It’s what the end of one often feels like: noise, motion, and excitement… with very little money actually coming in….” Coastal Journal https://lnkd.in/ehYwHSHe

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.

It's research like this that makes Siggraph so special, scientists and researchers actually moving the technology of art forward. When HDR becomes more ubiquitous, it'll be because of research like this. This is where technology like Gaussian splats, stereo imagery, rendering engines get born and gain momentum.

Does #MXL replace SMPTE ST 2110? NO!! During one IABM Technology & Trends Roadmap working group calls, it was clear that many of us kept hearing incorrectly that MXL (Media eXchange Layer) is a replacement for ST 2110.  While at the North American Broadcasters Association (NABA) event this week in New York, I asked Felix Poulin from CBC/Radio-Canada and Vincent Trussart from Grass Valley to help clear this up. Thanks to Felix for providing a clear drawing! Help to get this detail out by reposting and sharing with your peer groups. For additional detail, figure 15 of this European Broadcasting Union (EBU) #DMF document shows the difference between streaming and exchange layer https://lnkd.in/eqsgAnxq
