KNME New Mexico PBS
Advancing broadcast engineering with ATSC 1.0 and 3.0 — a comprehensive NextGen TV transition for New Mexico PBS, operating as KNME-TV since 1958.
Background
About the Project
Since 1958, New Mexico PBS (NMPBS), operating as KNME-TV, has been a leader in public television and broadcast innovation. Facing the challenges of transitioning to next-generation broadcast technologies while optimizing existing systems, KNME partnered with HVS to implement cutting-edge solutions in ATSC 1.0 and ATSC 3.0.
Challenge
- Transition to ATSC 3.0 (NextGen TV): Upgrade infrastructure to support next-gen standards without disrupting existing ATSC 1.0 services.
- Optimize Spectrum Usage: Combine two stations on a single ATSC 1.0 transmitter.
- Implement Advanced Technologies: Integrate ModCod design, High Dynamic Range (HDR), and explore virtual channels.
- Expand International Content: Test and implement translator services and virtual channels for international news providers like Deutsche Welle.
Solution
HVS Turnkey Approach
HVS provided a turnkey solution encompassing studio design, equipment procurement, and full integration of the technical infrastructure. Key upgrades included:
- ATSC 3.0 Deployment: Facilitated the installation and commissioning of a new ATSC 3.0 transmitter, enabling NextGen TV services with enhanced audio, video, and interactive capabilities.
- Spectrum Optimization: Engineered the combination of two stations onto a single ATSC 1.0 transmitter, reducing operational costs and freeing up spectrum for additional services.
- ModCod Design & HDR: Improved signal quality and bandwidth efficiency through advanced ModCod schemes and enhanced visual quality with HDR technology.
- Virtual Channels & Translator Testing: Enabled the provision of international content by testing and implementing virtual channels and ensuring reliable signal propagation.
- Educational Datacasting: Deployed SpectraRep's EduCast to deliver educational content via ATSC 3.0, reaching students without broadband access.
- Manufacturer-Agnostic Approach: Selected the best equipment from any vendor, ensuring optimal performance and cost-effectiveness tailored to KNME's needs.
- Rigorous Lab Testing: All solutions were thoroughly tested in HVS's in-house lab to ensure reliability and performance before deployment.
