AI Innovations in Testing and Monitoring: How Machine Learning is Transforming Testing and Monitoring On Real Devices - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Digital Online OperationsArtificial intelligence (AI) has emerged as a pivotal tool for video service providers in ensuring an exceptional quality of experience (QoE) for their end-users. Machine learning (ML) neural networks currently enable content providers to enhance encoding and compression for video-on-demand (VOD) assets. However, evaluating live and linear content remains challenging without a reference stream. This paper explores an innovative methodology to assess video quality from the user’s perspective on physical devices. This approach mirrors human interaction through AI and computer vision to detect defects. Extensive testing of third-party applications using this technique can increase customer retention for video services. With rapid advancements, AI has the potential to transform video quality assurance.

AM Carrier Power Reduction in All-Digital Service Mode MA3 - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Radio TopicsSome AM radio stations have turned off their analog broadcasts and converted to digital-only operations, with the possibility of better coverage, improved ratings, and more competitive features. Since a modulated analog signal is not present, it is possible to reduce the main carrier power in All-Digital service mode MA3 without adversely affecting audio quality and availability. This might not only decrease conversion costs but could also save broadcasters thousands of dollars per year in utility bills. Alternatively, the resulting power savings could be applied to the digital subcarriers, thereby enhancing the robustness of the digital signal.
Since receivers use the main carrier to demodulate the digital signal, reducing its power could potentially degrade reception performance. Specifically, HD Radio receivers use the main carrier to correct frequency differences between the received and transmitted signals, and to normalize the amplitude of the digital subcarriers across the allocated channel bandwidth. Xperi has analyzed and simulated the effects of reduced main carrier power to determine an acceptable decrease and quantify the resulting degradation. Results indicate that a 6-dB carrier power reduction, with a concomitant 4-dB reduction of the two OFDM reference subcarriers, should have a negligible impact on signal robustness.
The next logical step in assessing the viability of reduced MA3 carrier power was to validate these predictions by measuring performance in a real-world automotive environment, using Hubbard Broadcasting station WWFD in Frederick, MD. Field tests were performed over multiple routes to expose the signal to a variety of terrain, speed, interference, and shadowing conditions.
This paper will review Xperi’s analytical and simulated performance predictions and will present field test results that successfully validate them. Results indicate that reducing carrier power by 6 dB and reference subcarrier power by 4 dB has an insignificant effect on WWFD’s MA3 digital audio coverage area.

AM Radio FCC NRSC Compliance Reports - $15
Date: April 14, 2023Topics: 2023 BEITC Proceedings, Radio TechnologyEvery year, each of the more than 4,000 FCC-licensed AM radio stations in the US are required to make and document “NRSC measurements” and place the reports in the station official files. While these measurements can be done by local station engineers, the measurements are relatively complex and can require sophisticated equipment to be completed properly. Compiling the measurements into a document that meets FCC requirements can also be difficult. The number of contract engineers capable of making the making the measurements and providing professional reports continues to decline. The cost of providing these reports is increasing, making it even more difficult for station management to meet the FCC report requirements. This paper discusses some history behind these measurements, reviews the details as specified in the FCC rules and NRSC Standards, and offers suggestions on how to compile the measurement data to create professional reports.

An Innovative In-Service Antenna Monitoring System to Protect Your Antenna and Transmission Line - $15
Date: April 3, 2024Topics: 2024 BEITC Proceedings, Broadcast Facility DesignAntenna and transmission line systems are critical components of the broadcast transmission infrastructure. Unfortunately, traditional monitoring is limited simply to reflected power. Depending on speed and accuracy of the monitoring equipment, some arcs or small reflected changes can go unnoticed. SPINNER introduced the Antenna Monitoring System (AMS) in 2015. It scans for arcing from the transmitter building all the way up to the end of the antenna. The AMS provides protection to the entire RF system by alerting and or opening the transmitter interlock when an arc is sensed. While the AMS provided protection, it couldn’t tell you where the fault occurred. We have innovated again by adding Distance to Fault (DtF) analysis in the AMS 2.0 system. This paper will discuss the methodology and benefits of the AMS 2.0 along with some real-world results where the AMS protection detected and closely located faults before significant damage occurred.
