Directtv 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, directtv claims to have sued over 24,000 end users as of March 17, 2004, including celebrity O.J. Simpson. directtv bases its suits on purchase records of ISO-7816 Smart Card devices. Although these devices could be used to rewrite directtv's access cards, there are countless legitimate uses for them as well. This has caused controversy, since directtv is making the assumption that all purchasers of the devices are pirates.

Like its competitors, directtv offers high-definition television (HDTV) and interactive services.
To handle the proliferation of bandwidth-intensive HDTV broadcasting, directtv rebroadcasts local HDTV stations using the H.264/MPEG-4 AVC codec while employing a newer transmission protocol (DVB-S2) over the SPACEWAY-1 and SPACEWAY-2 satellites. This allows directtv 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.
DirectTV is defending a lawsuit that alleges directtv lowered HDTV picture resolution below that of the industry's accepted definition of HDTV. DirectTV counters that its high definition picture quality is comparable to or better than that of any other TV service. [3]
To receive the channels encoded in MPEG-4 requires newer receivers such as the H20 as well as the 5-LNB Ka/Ku dish. directtv has contracted with Korea's LG Electronics and France's Thomson to manufacture these new receivers. LG Electronics offers the Model # H20-600 receiver while Thomson provides the Model # H20-100 receivers.
directtv uses the less advanced H10 receiver only when the customer cannot receive local stations. [4]
The HD channels offered by directtv are:
directtv also broadcasts FSN in HD in various markets, on different channels in the 90s range, for certain games.
directtv broadcasts some of the NFL Sunday Ticket package in HD for an additional fee. This service is only available to customers that purchase the NFL Sunday Ticket Super Fan for an additional $99.
Local network affiliates of (CBS, ABC, NBC, and FOX) broadcasts in HDTV are available in major markets.

directtv Local channels
directtv also offers local channels (CBS, ABC, NBC, Fox, PBS, The CW, MyNetworkTV, i: Independent Television (in markets that carry that network), and some independent stations) for many markets. In markets that lack a CW affiliate, directtv includes WSFL from Miami or KSWB from San Diego. Subscribers located where they cannot receive a decent terrestrial television signal can receive feeds from New York and Los Angeles for CBS, ABC, NBC, and Fox, though a waiver from the local stations may be required to allow this, approved at their discretion. National PBS and i channels are also available.
In the largest markets local channels are carried on the satellite at 101°W. In some smaller markets, the local channels are carried on a second satellite located at 119°W which requires a slightly larger dish with two or three LNBs or the newer Ka/Ku 5-LNB dish. In a few smaller markets, local stations are located on a satellite at 72.5°W that requires a second dish to be installed.
In late 2005 directtv began providing local HDTV channels to the largest markets, requiring newer receivers with a larger dish capable of receiving signals from up to five satellites at once. The Ku-band signals on the newer Ka/Ku dish are received from 101°W, 110°W, and 119°W, while Ka-band signals are from 99°W and 103°W.
In late 2006, directtv, announced plans to offer local channels, in 100% of markets by the end of 2007.
Local television channels are transmitted over optical fiber links, Ku-band satellite uplink, microwave, and conventional terrestrial transmission to uplink centers located throughout the United States.wallmart
