The Paralympics Extra channels will show action from the Games from August 30 to September 9 on Sky, Freesat, Virgin Media and Freeview HD, as well as being available online.
Sky customers can press the Red Button to access the video feeds, but they can also watch the channels at 450, 451 and 452 on the electronic programme guide. Viewers with Sky+ HD will see HD versions, while everyone else will just get standard definition.
Freesat will also broadcast the three Channel 4 Paralympics Extra channels at 150, 151 and 152 on its EPG. Freesat HD users will get the HD versions.
Virgin Media will offer the channels at 550, 551 and 552 in high definition on cable TV, or in standard definition at 553, 554 and 555.
Freeview HD viewers will not get the channels, but will be able to view some of the extra coverage by pressing the Red Button while watching Channel 4 HD.
They will only get one additional video feed, as opposed to three on other platforms, and the coverage will not be available on non-HD Freeview equipment.
Paralympics Extra channels will start appearing on the participating digital TV EPGs from August 28. Depending on the TV platform, the channels should be called Channel 4 Para 1, Channel 4 Para 2 and Channel 4 Para 3.
Viewers with personal video recorder (PVR) services will be able to record the coverage.
During the London 2012 Olympic Games, the BBC offered 24 live HD channels on various TV platforms, broadcasting every sport going on at every venue. The initiative proved a huge success, with every live streamed event attracting more than 100,000 viewers.
Channel 4 will use its three video feeds to offer an extensive range of live coverage of events from the Games, which get underway after the Opening Ceremony on August 29.
"The launch of these new Channel 4 HD services is fantastic news for our customers," she said.
"The additional 24 BBC Olympic HD channels on Freesat proved enormously popular and we know that the addition of the Channel 4 Paralympics channels will also be another huge hit with Freesat viewers: the perfect conclusion to a brilliant summer of subscription - free sport on Freesat."
Channel 4's commercial and business development director Sarah Rose added: "We're thrilled Freesat customers will be able to access C4 Paralympics Extra, Channel 4's three dedicated channels of live coverage of the London 2012 Paralympic Games.
"This further contributes to Channel 4's ambition to bring viewers the most extensive coverage of the Paralympic Games ever broadcast in the UK."
Channel 4 has also announced plans to launch dedicated Paralympic apps for iOS and Android mobile smartphones and tablet devices.
Channel 4 has further created a dedicated Paralympic section of its website to feature continuously updated live text commentary, news, results and medal tables.
In a statement heralding its Paralympic coverage, Channel 4 said: "After years of working and waiting, countless months of heady anticipation, weeks of building excitement, and a not-too-shabby test event, the Paralympics have finally arrived.
"For 12 days, viewers of Channel 4 will witness unfettered sporting brilliance, courage, talent, triumph and tragedy, as dreams are made and broken in the cauldron of top class competitive sport."
