Advanced IBOC Coverage and Compatibility Study (Final Report) Available
This report adds sections dealing with compatibility (impairment to analog main FM channel reception from same-station IBOC transmissions) and a means for estimating increases in IBOC coverage at elevated digital powers.
 
NPR Labs Online Viewing Applications for Public Radio and Television
The NPR Labs Public Television Online Viewing Application and the NPR Labs Public FM Radio Online Viewing Application comprise a set of tools that let users dynamically explore mapping and demographic data for PTFP-qualified FM and TV transmitters.
The tools are now freely available your interaction, and are intended for anyone affiliated with a PTFP-qualified FM and/or TV transmitter. Please see the abstracts introducing these tools and the scope of work in these PFTP studies.
 
20100301: REVISED NPR Labs PAD Applications for iBiquity v4.x and later Importer software
NPR Labs has learned that the PAD applications provided free-of-charge to NPR Members are incompatible with iBiquity's version 4.x and later Importer Software. NPR Labs has been working to revise the software, and is developing the replacement using the PADSDK provided through iBiquity Digital Corporation.
The alpha version has recreated the software as a Windows service with 'plug-in' components to operate the desired PAD stream, flexible scheduling to allow different services to push PAD to the same network port at different times.

PAD Final Report

PAD Workshop

NPR's activity under the CPB PAD grant has focused on:

  • Complementing the PAD/PSD activities recently completed by PRI
  • Furthering network-distributed PAD for the public radio system's most listened-to programs
  • Instituting Vendor Relationship Management (VRM) to influence receiver manufacturers to deploy improved PAD designs to better serve the public radio audience
  • To document and demonstrate station-level baseline PAD implementation, and the economics of those activities for all public radio stations
  • NPR Labs PAD Software
