AT&T U-verse is a suite of Internet Protocol (IP)-based products and services , including AT&T U-verse TV, AT&T U-verse High Speed Internet, and AT&T U-verse Voice telephone, (VoIP) service. U-verse utilizes both fiber-to-the-node and fiber-to-the-point technology to obtain speeds upwards of 25Mbps to the user's home. AT&T is attempting to leapfrog current cable systems by offering features like a DVR that can record up to 4 shows at a time and is programmable from any web-connected computer.
Short description
U-verse TV is delivered over IP from the head end to the consumer's set-top box. U-verse uses H.264 (MPEG-4 AVC) encoding which compresses video more efficiently than the traditional MPEG-2. Broadcast channels are distributed via IP multicast, allowing a single stream (channel) to be sent to any number of recipients. The system is also designed for individual unicasts for video on demand, central time shifting, start over services and other programs desired by only one home at that particular time. The set-top box does not have a conventional tuner, but is an IP multicast client which joins the IP multicast group corresponding to the stream ("channel") desired. In the IP multicast model, only the streams the customer uses are sent. The customer's connection need not have the capacity to carry all available channels simultaneously.
The customer's premises are served primarily by VDSL from large fiber fed neighborhood boxes, known as VRADs. In newer developments, U-verse may also be deployed over FTTP. The network was designed for speeds of 20-25 megabits down, 1 to 3 megabits up, with the majority of the bandwidth devoted to the TV programming. These speeds are generally reliable within 3,000 feet (900 m) from the neighborhood gateway, though AT&T has announced they will bond two pairs of wires to extend those speeds to 5,000 feet (1,500 m).[citation needed] Homes closer than that can receive higher speeds downstream, possibly 40-50 megabits up to 1,500 feet (500 m).[citation needed] AT&T has local facilities (cross connects) within 5,000 to 6,000 feet (1,500 to 1,800 m) of most homes, some of which already are fed by fiber.[citation needed] Inside the customer's home the new services are carried over Ethernet or a HomePNA home CATV network.
U-verse TV
U-Verse TV is AT&T's television service,part of the U-verse bundle of services, which is 100-percent Internet Protocol (IP)-based video service. [1] U-Verse delivers its digital television services to its customers via phone lines or over fiber using Internet protocol (IPTV - Internet Protocol TV). The industry-leading IP services are delivered over AT&T's expanded fiber network. AT&T is bringing fiber even closer to customers' homes using fiber-to-the-node (FTTN) and fiber-to-the-premises (FTTP) technologies.
Total Home DVR
Total Home DVR is a feature of U-verse TV and was introduced to U-Verse on September 9, 2008. It allows customers to watch recorded shows on any TV in the house with a set-top box (STB).
Total Home DVR also allows you to:[2]
- Pause a recorded show and pick up where you left off in another room.
- Play back the same recorded show on different TVs, at different points.
- Play back up to 4 recorded shows at once. Up to 3 can be HD recorded programs.
- Organize recorded content by series.
- You can store up to 37 hours of HD content or up to 133 hours of SD content
- Record more of the show you want to see with soft padding, which automatically adds 1 minute to the beginning and 2 minutes to the end of each pre-scheduled recording.
- Set the DVR while on the go from your PC or wireless phone.
U-verse Internet
U-verse enabled internet is AT&T's internet service from the U-verse bundle of services. AT&T U-verse enabled High Speed Internet uses fiber technology,for high speeds and performance, all with email and content provided through AT&T Yahoo!. AT&T U-verse enabled Internet also gives you the added feature to program your DVR using the internet. Web remote access to your DVR means you can control your U-verse TV from across the street, or across the country anywhere you have internet access [3].
AT&T U-verse High Speed Internet is offered in four speed tiers:
- Express - Download Speed: Up to 1.5 Mbps; Upstream Speed: Up to 1.0 Mbps
- Pro - Download Speed: Up to 3.0 Mbps; Upstream Speed: Up to 1.0 Mbps
- Elite - Download Speed: Up to 6.0 Mbps; Upstream Speed: Up to 1.0 Mbps
- Max - Download Speed: Up to 10.0 Mbps; Upstream Speed: Up to 1.5 Mbps
- Max 18 - Download Speed: Up to 18.0 Mbps; Upstream Speed: Up to 1.5 Mbps
A customer must order U-Verse TV if he intends to have U-Verse Internet service; however, a customer can cancel his TV after initially ordering both. The exception to ordering U-Verse Internet only is under the condition where a user does not have access to AT&T's regular DSL, but does have access to AT&T's U-Verse Internet service.
U-verse Voice
AT&T U-verse Voice is a voice communication service delivered over AT&T's IP network. U-verse voice is currently available only in some areas. Customers subscribing to both AT&T U-verse TV and Voice are provided an added feature, Call History and Click to Call, which displays missed and answered calls on your TV screen and with a click of your remote returns a call
History
In June 2004, AT&T announced Project Lightspeed. Alcatel-Lucent was named as the Systems Integrator for Project Lightspeed. AT&T originally planned to reach nearly 18 million homes by the end of 2007,[4] a target not likely to be met until early 2009. U-verse will also be available to a limited number of homes in the old BellSouth region. AT&T has not announced whether they would offer faster 50-100 megabit symmetric service to the 1.5M homes announced by BellSouth before the purchase. [5]BellSouth had already invested in fiber to the curb, so the higher speeds would require little additional investment. Some parts of San Antonio, Texas offered SD TV commercial service in June 2006 with 30 HD channels available to some in December, although limited to a single channel per household. AT&T has announced they will offer two HD channels to a home, which will allow watching one channel while recording a second. As of the end of July 2008 many U-Verse customers finally have the two HD channel offering. The standard definition packages currently offer as many as 400 channels. Pricing varies widely, with "special offers" changing rapidly. The channel lineup and pricing of AT&T U-verse is similar to most cable and satellite systems. There may, of course, be differences between a local cable provider and the AT&T U-verse selection. For a listing in a specific area, consult the U-verse channel lineup. Voice over IP is available in only some U-Verse areas in July, 2008.
