4. iBiquity
-Is a company formed by the merger of USA Digital Radio and Lucent Digital Radio, with the goal of creating an in-band on-channel (IBOC) digital radio system for the United States.
-It can operate on both AM band and FM band broadcasts either in a digital-only mode, or in a "hybrid" digital+analog mode. Most broadcasts for the foreseeable future will use the hybrid method, reportedly giving AM stations "FM quality" sound, while allowing FM stations to achieve "CD quality" audio or carry multiple audio programs.
-The technology is marketed under the term HD Radio. Note the "HD" in HD-Radio stands for "Hybrid Digital" not "High Definition" in more popular usage.
