FM broadcast system competitive with satellite radio
TLDR
In this paper, a media broadcast and distribution system is described which substitutes storage for communications, allowing more efficient use of scarce bandwidth resources, allowing a terrestrial FM broadcaster to offer a larger number of higher quality audio channels than satellite radio services such as Sirius and XM Satellite Radio.Abstract:
A media broadcast and distribution system is disclosed which substitutes storage for communications, allowing more efficient use of scarce bandwidth resources. One embodiment allows a terrestrial FM broadcaster to offer a larger number of higher quality audio channels than current satellite radio services such as Sirius and XM Satellite Radio. This embodiment also has features that offer a better user experience than with personal audio devices such as Apple's iPod™. Another embodiment allows satellite radio services to expand their video offerings.read more
