WUSF-FM Tests Conditional Access
The Florida radio station is testing conditional access with HD Radio: This is related to the recent announcement that NDS RadioGuard will be used to offer content selectively to listeners based on their receiver's unique serial number. One key part of this testing is looking into replacing sub-carrier, low-quality broadcasts of radio reading services for the visually impaired with higher quality HD Radio channels that would be locked to those qualified to listen.
