TV Data Capacity DTV stations have mbps capacity Bits not used for video may be used for IP traffic HD requires mbps, SD 3-4 mbps ATSC standard problematic but improving (currently best for NRT applications) Analog TV has datacasting capacity as well (3-4 mbps)

Wi-Fi/802.11b Wireless Provides access to IP streams and file transfers Office and home networks increasingly popular Provides broadband services in competition to DSL and cable modems Guerilla or community wireless Security issues may limit access

Other Opportunities 3G (or 2.5G) wireless Multichannel Video Distribution & Data Service (12 GHz) LMDS broadband (27-31 GHz) MDS/ITFS broadband (2.6 GHz) Spectrum from UHF TV channels (Lower 700 MHz band) (FCC )

Asset Management IP oriented new spectrum opportunities permit on demand programming Requires accurate and accessible knowledge about what is available -- metadata CPB now sponsoring Public Broadcasting Metadata Model to develop a shared approach to describing programming and program elements
