Blu - ray Disc Blu - ray Disc ( BD or Blu - ray ) is a high - definition home entertainment format on the standard 120mm optical discs . Launched in 2006 , it competed briefly , but fiercely , from 2006 to 2008 with HD DVD before becoming the standardized high - definition home entertainment format . Regions . Blu - ray releases , much like DVD s , are divided into separate regions to restrict the areas specific discs can be played . The following is a guide to the regions and which areas of the world they relate to : History of " Star Trek " on Blu - ray . " Star Trek " releases on Blu - ray commenced in with season one of " The Original Series " . The full series of and were later released . The animated episode 2006 HD remastered version was also released on the TOS Season 2 Blu - ray ; the entire " Animated Series " was released on Blu - ray as part of the " Star Trek 50th Anniversary TV and Movie Collection " ( with a following later ) . In , the " " release of twelve " The Original Series " episodes was announced , noting that it would include previously unseen footage , including deleted scene s and bloopers . " Star Trek : Deep Space Nine " . CBS has commented that a Blu - ray release is a possibility . In a post on Twitter , Michael Okuda commented , " " We ' ve heard that CBS execs would love to give DS9 the HD treatment , if sales for TNG HD continue to support it . " " Craig Weiss of CBS Digital commented that there has been talk about remastering " Star Trek : Deep Space Nine " . As of December 2014 , however , there has been no official decision made public . Regarding DS9 on Blu - ray , Roger Lay , Jr . commented , " " We ' re all ready to go , man . I ' ve been finding some really cool stuff related to the making of " Deep Space Nine " that I can ’ t wait to put on a Blu - ray set . " Enterprise " is out on Blu - ray as well – we released that simultaneously with TNG . So DS9 seems like the next logical choice " " . Lay , Jr . also commented , " Deep Space Nine " , we all want to do it . I ' ll tell you that . I think it ' ll be more difficult in the sense that by season 4 of DS9 you had digital elements , a lot of digital elements . By the Dominion War they were doing entire sequences that were digital , there were no models anymore . On TNG we ' ve had all these plates and all these model motion - control shots to re - composite . You don ' t have anything like that now . So you kind of have to recreate everything when it comes to that stage . I think the first three seasons will be fairly close to what has been done on " Next Gen " , but by season 4 and beyond it will get a lot more complicated . So all of that has to be factored in . And honestly they have to look at the sales of " Next Gen " and see how it did overall and what kind of a budget they could allot for " Deep Space Nine " . So will it happen immediately ? I don ' t know . Do we all want to go and bring " Deep Space Nine " back ? Absolutely . I think the next couple of months will be crucial . It will also be crucial to fans who have been waiting for all seven seasons of TNG to be released . It sounds sad , but it ' s a business decision when it should be a creative one . But you need sales in order to put out more product , it ' s as simple as that . We ' re hoping to get news within the next several months . But if fans want to do anything to make that happen , pick up these Blu - ray sets right now , because the entire " Next Generation " collection will be out . " "
