ATSC 3.0 Test Station in Cleveland
NAB and the Consumer Technology Association established an ATSC 3.0 test station in Cleveland, OH using facilities at Tribune-owned WJW.  The goal of this project, being co-sponsored and co-funded with the Consumer Technology Association, is to provide a testbed to establish “proofs of concept” for various ATSC 3.0 elements and to act as an incubator for new products and services based on ATSC 3.0.

FM Radio in Smartphones
Through 2016, we tracked the sales and capabilities of the top-selling smartphones sold in the U.S. – which we defined as the upper 70 percent of U.S. sales – typically equating to approximately the 20 most popular phone models of the day. We explored the internal design of these phones to determine their FM reception capabilities. The chart below shows historical data since we began collecting it, up to the most recent data available (fourth quarter of 2016), presented as annualized summaries.

Single Frequency Network Analysis
Verified that the HD Radio™ system will permit a smooth evolution from current analog Amplitude Modulation (AM) and Frequency Modulation (FM) radio to a fully digital In-Band On-Channel (IBOC) system.

Addressable HD Radio Receivers (“Smart Radio”) Project
Developed requirements and a proof of concept for a “smart” digital radio receiver that allows the user to create a customizable listening experience. HD Radio broadcast technology can be used to send audio content, either program material or commercials that is “pre-stored” in the receiver. Time slots in the live broadcast can be replaced with pre-stored content depending on user selection.

FM IBOC Asymmetric Sideband Transmission
Implemented and tested FM IBOC HD Radio asymmetric digital sideband broadcast configurations to enable an increasing of digital power while minimizing interference to adjacent stations. Developed transmission equipment software updates which support this new operational mode.

VHF/UHF Antennas for Integration in Mobile Devices
Designed and built prototype small antenna systems suitable for integration into a cell phone (or similar device) which operates over FM band (88-108 MHz) and TV band (54-88 MHz, 174-216 MHz, 470-698 MHz) frequencies, and suitable for reception of FM radio (analog and/or HD Radio digital for FM band) and ATSC mobile digital TV (DTV) signals.

Speech Recognition Research
Supported development work to take speech recognition technology to the practical level to enable automatic captioning and obscenity filtering. The work was done by Speech Conversion Technologies, Inc.

Radio in Cell Phones
Provided technical information and support to the broadcast industry on the important issue of including radio receivers in cell phones. As part of this effort, conduct technical, regulatory, and/or economic studies with the goal of answering questions and removing obstacles to this effort.
Study of Potential for FM Radio to be a Universal Feature on Cellular Handsets

Digital Converter Box Testing
Evaluated a total of 18 different manufacturer/brand models of commercially available digital-to-analog converter boxes, including several with the analog pass-through feature The boxes were evaluated based on Radio Frequency (RF) performance, ease of use, packaging and instructional literature included as well as external features.
