New Networks Expand and Provide New Markets
o IP Video standardization will enable applications and
services beyond what is available in today’s
proprietary networks
• DVR Control from Office PC, PDA or Cell Phone
• Advanced DRM will enable sharing of content in a way
that empowers the use and protects content.
o Providing Connectivity will require standardization
beyond the IP layer
• Security
• Protection of Network Devices
— Viruses
— Spyware

Moving Forward
o AT&T is currently in a controlled launch.
o Our technology direction will continue to rely
on the development of standards to not only
enable our network, but to empower our
customers to use it to its fullest potential
o IPTV’s inherent connectivity will enable new
services and market opportunities.
