Samsung is tossing their hat into the ring of HD Radio with an announcement that they will be developing chipsets for this up-and-coming radio format. This is pretty significant because the chips being developed by Samsung are of the low-power and low-cost variety, therefore HD Radio may be able to tap a market that it has yet to grasp: portability. This expands the previous limitations of HD Radio and could allow for portable HD Radio receiver and even implementation into cellphones and other portable devices (Zune?).
