DirecTV is a direct broadcast satellite (DBS) service based in El Segundo, California that transmits digital satellite television and audio to households in the United States of America. DirecTV is owned by DirecTV Group, which is controlled by News Corporation's Fox Entertainment Group.

General information

DirecTV typically uses a fixed 18-inch diameter dish antenna to receive its signals. Slightly larger, 18x24-inch elliptical antennas (which receive signals from three geostationary satellite positions simultaneously) are becoming more common as DirecTV (as well as other DBS services) attempt to squeeze more programming onto their growing systems — particularly local television network affiliate stations, as well as HDTV programming. DTV is now installing a dish that has five LNBs (receives signals from five satellites) for HDTV programming in select markets.

DirecTV offers local channels to 93% of U.S. residents (including Alaska and Hawaii). Local channels are transmitted over optical fiber networks to the Castle Rock Broadcast Center, in Castle Rock, Colorado, where they are uplinked.

As of November 30, 2005 DirecTV has over 15 million customers in the U.S. and 1.57 million in Latin America. 2005 revenues are $3.15 billion.

The Economist has suggested that News Corporation would eventually like to merge DirecTV with Sky, its British satellite operation, and possibly its Asian Star and Australian Foxtel networks to form a global satellite TV company.

History

• DirecTV was launched in 1994 by General Motors subsidiary Hughes Electronics. It was the first high-powered DBS service in the world.
• In 1998 DirecTV acquired its partner, USSB for $1.3 billion. In 1999 DirecTV acquired PrimeStar for $1.83 billion. In 2003, a merger with EchoStar, owner of Dish Network, fell through.
• On December 22, 2003, General Motors sold controlling interest in Hughes Electronics to News Corporation.
• On November 15, 2005, DirecTV stopped carrying Music Choice audio-only channels, replacing it with 72 channels of XM Satellite Radio.

Access card history

DirecTV transmits programming with encryption to mitigate signal piracy. The receiver (also known as an IRD, or "integrated receiver-decoder") utilizes ISO7816 smartcards which tell the receiver how to decrypt the programming for viewing. In a continuing effort to combat piracy, DirecTV is now utilizing a fifth generation of access cards.

• P1, also known as F cards, were used until 1997. F cards have a picture of a satellite on the front.
• P2, also known as H cards, were introduced in 1996 to replace F cards. H cards look the same as F cards. H cards were in use until 2002.
• P3, also known as HU cards, were introduced in 1999 and are no longer supported. HU cards have a picture of a football player on the front. HU cards originally shipped with receivers with serial numbers above 0001 700 000. These were removed from circulation due to high piracy plaguing the system.
• P4 cards were introduced in 2002 and are currently still in use. P4 cards are labeled "Access Card: 4."
• D1 cards were introduced in 2004 following compatibility problems with the P4 cards in some receivers. This is the current "standard issue" card. These cards can be identified by the silver edges, and simply bear the word "DirecTV" on the front (no number).
• D2 cards were introduced in 2005. These cards can be identified by a two-toned blue dot pattern resembling the DirecTV logo in addition to the DirecTV logo and the words "DirecTV Access Card". They have no number on the front.

DirecTV has long been a victim of an active signal piracy underground, but has recently begun to crack down on illegal reception of its signals. On its anti-piracy website, DirecTV claims to have sued over 24,000 end users as of March 17, 2004, including celebrity O.J. Simpson. DirecTV bases its suits on purchase records of ISO-7816 Smart Card devices. Although these devices could be used to rewrite DirecTV's access cards, there are countless legitimate uses for them as well. This has caused controversy, since DirecTV is making the assumption that all purchasers of the devices are pirates.

High-definition television (HDTV)

Like its competitors, DirecTV also offers high-definition television (HDTV) and interactive services. Its self-branded digital video recorders (DVRs) originally were based upon technology licensed from TiVo in an agreement that has been largely supplanted by a new partnership with News Corporation-owned NDS.

To handle the prolifiration of bandwidth-intensive HDTV broadcasting, DirecTV is now broadcasting local HD content using the MPEG-4 AVC/H.264 codec while employing a newer transmission protocol (DVB-S2) over their new SPACEWAY-1 satellite and SPACEWAY-2 satellite. This allows DirecTV to squeeze much more HD programming over its satellite signal than was previously feasible using the older MPEG-2 compression and DSS protocol it has been using.

It is speculated (and many say testable) that both DirecTV and their competitor Dish Network have also reduced the quality of their Standard Definition Broadcasts in order to clear more bandwidth for HDTV.

Subscribers must acquire a new set-top box (the H20 receiver) and a 5-LNB dish (referred to as a "Ka/Ku" dish) in order to receive the new programming encoded with MPEG-4. DirecTV has contracted with Korea's LG Electronics to manufacture these new boxes. LG Electronics manufactured Directv H20 boxes are only with the Model # H20-600

The Following HD channels are broadcasted by Directv in the hd lite Format

The HD channels offered by DirecTV are:

• 70 - HBO HD
• 71 - Showtime HD
• 72 - ESPN2 HD
• 73 - ESPN HD
• 74 - Universal HD
• 75 - TNT HD

• 79 - HDNet
• 101 - CD USA

DirecTV also broadcasts some of the NFL Sunday Ticket in HD for an additional fee.

Local stations (CBS, ABC, NBC, and FOX broadcasts transcoded in MPEG-4 are currently being rolled out in major markets. Where not available through satellite, local HD channels can be received over the air using an antenna for free of charge.

Satellite fleet

Local channels

DirecTV also offers local channels (CBS, ABC, NBC, Fox, PBS, WB, UPN, and some independent stations) for many markets. In the largest markets, the locals are carried on the main satellite. In smaller markets, the locals are carried via another satellite where HD and most Spanish language programming is located, requiring a slightly larger oval dish, capable of receiving from both satellites simultaneously. Generally, this dish will include three LNBs so it can see three satellites. In a few smaller markets, local stations are located on yet another satellite, requiring a second dish pointed in a different direction. In markets that lack a WB affiliate, DirecTV includes WBZL-TV from Miami or KSWB-TV from San Diego; both stations will join the CW network in September, 2006. Subscribers located where they cannot easily receive terrestrial television broadcasts can receive feeds from New York and Los Angeles for CBS, ABC, NBC, and Fox. A national PBS channel is also available. In late 2005 DirecTV began the rollout of HD locals in the largest cities, requiring new set-top boxes and an even larger dish capable of seeing five satellites at once (at 99°W, 101°W, 103°W, 110°W and 119°W).
