U-verse is a service offered by AT&T that developed based on Internet Protocol television technology and can be packaged to include Internet, TV and voice over Internet protocol, or VoIP, services. The U-verse service can be delivered to the customer through either a fiber-to-the-node or fiber-to-the-premises network.
Another method that AT&T uses to deliver U-verse service to its customers is through a network interface device that utilizes a current loop made from copper wire. When U-verse is delivered through an FTTN connection, subscriber lines are digital and can deliver high speeds through VDSL or ADSL2+ technology. As of 2014, customers who wish to subscribe to U-verse television services must reside within 3,500 feet of a VRAD with an available port to connect to.
Television services delivered through U-verse are encoded in MPEG-4 AVC and can multicast up to four channel streams at once. Video-on-demand, central time shifting and start-over services are delivered through individual unicast channels. Channels offered on U-verse television can be grouped into time-delayed, high-definition, local, sports and regional channels.
As of 2014, all AT&T U-verse subscribers can receive Internet speed packages that range between 3 and 24 megabits per second. Certain regions and markets can receive even higher speeds.
