Also known as a "Plus One" channel or the "Catch up broadcast", this is a supplementary TV channel in which the programmes shown on that channel are repeated an hour later on a different channel. Essentially a delayed feed with a slightly different network logo. Sometimes called "catch up" channels by viewers, so-called because they give viewers a second chance to catch a program that might have clashed with something else they were watching. For example, You could watch Merlin (2008) first on BBC One, then switch over to Dave ja vu to watch the now hour-displaced Taskmaster.
There are numerous examples on British satellite, freeview, and cable TV, including +1 versions of terrestrial networks such as Channel 4 and ITV, though the BBC (rather strangely) doesn't use them note .
For legal reasons too numerous (and too complex) to list here, occasionally, if the immediate repeat rights are unavailable for the +1 channel (which applies mostly to films, and even this is extremely rare), or if the programme on +1 is region-specific (such as news or local weather), the channel may show a "we'll be right back" screen during the programme that would otherwise air. +1 channels can also be slightly confusing when carrying "live" news or sports. Some channels avoid this by intentionally removing the news from their +1 channels.
Needless to say, catching the last two minutes of something you would have been interested in seeing is doubly annoying when it's on Plus One, meaning you've managed to miss it twice within an hour...
With the rise of online catchup services that started to surface in 2007, such as BBC iPlayer, All 4, and HBO Go to name a few, missing a programme at all has become somewhat irrelevant. We are creatures of habit, however, and the +1 channels still fit a niche of viewers that like to watch a show as close to the live broadcast as possible without moving from their sofa.
Network Decay can occasionally cause this in a formerly-independent channel. This can occasionally be subverted by the network running a spare timeshift channel temporarily in order to retain hold of an EPG position prior to a new channel launching- X League / Pulse did this with three(!) other channels, and Living TV had a +2 for a while, before it became Living HD.
If you're wondering why there are so many British references on this page, it's because the +1 channel came from the United Kingdom prior to the likes of iPlayer existing, as +1 channels were used as an incentive to get people to ditch traditional terrestrial television until the digital switch-over. Of course, it's not limited to the UK, but it has the most prominent examples.
Related is cable networks in the United States that make both their East Coast and West Coast feeds available to everyone, or more rarely, re-air a truncated network block of what the network figures are the most watched and anticipated shows, sometimes and even more rarely out of order, usually after the West Coast feed or late night (thus sometimes giving three opportunities to view programming). On cable providers having a +3 or -3 feed has become less popular as they would rather carry more high definition programming than a feed featuring duplicate programming in the age of DVR's and on demand, which a second network feed would limit.
- Discovery +1 (and +1.5)
- Nick 2 in the United States, and Nicktoons Network in the UK.
- Averted in the US by running the same program twice within three hours on the same channel. Channels like History and Discovery generally tend to air programs this way to avoid a double channel for the West Coast feed. A show airing at 9 pm and 12 am on East Coast time ensures that the 12 am showing will air at the advertised 9 pm on the West Coast.
- Looking at the schedules of some channels in the UK that do timeshift, this technique doesn't avert it at all. On a few of them you get a three-hour block, repeated, and then the whole lot timeshifted by an hour on another channel. A couple do it in reverse, where two or three programmes leading up to a long documentary or movie will be followed by the two or three programmes that preceded it in reverse order. Particularly humorous on Channel 4 with their piano-roll ECPs where you blatantly see the repeated entries scroll past you.
- Fox News and MSNBC generally do this with their 8PM, 9PM, and 10PM shows. However, sometimes Red Eye comes on at 12AM instead of 3AM.
- Adult Swim's second half is usually a repeat of its first half. Made a little muddy by the fact that Saturdays feature less repeat programming and the occasional nights of programming decided by contest winners, when it is left to said contest winner as to whether the block repeats or not (they usually opt to air additional programming instead). Made even muddier on Sundays in that King of the Hill will have an "offset repeat." Considering that Cartoon Network/Adult Swim also has separate East and West Coast feeds, it's sometimes possible to watch something four times in a night. 4:00-4:30 AM is taken up by "DVR Theater", which caters to fans of recording and insomniacs with an original half-hour of programming that isn't repeated, usually consisting of reruns of the network's shows, parodic infomercials, Off the Air, and even the occasional repeat of "FishCenter" from [as]' website.
- Armed Forces Network caters the US soldiers and families living overseas. Since they broadcast worldwide, separate channels with the same shows are created to accommodate viewers living in either the Pacific or the Atlantic regions during normal time slot hours. AFN Spectrum generally repeats the same show every eight hours three times a day. A soldier in Japan can watch a show in the morning, but too early for soldiers living in Germany or Honduras unless they wait eight or sixteen hours.
- Food Network, Spike TV, and Discovery Channel will sometimes do the rare truncated version mentioned in the main article, depending on scheduling. For example, Food Network will re-air both of the day's episodes of Good Eats late-night, but flip-flop the airing order.
- Australian Pay TV has several channels with this feature but it's generally +2. Thus to those in Perth the main channel is their -2, allowing them to watch a show ahead of time if the Sydney-centric channel is offered on their system. It also causes an unintentional example with SBS in Queensland during summer due to New South Wales and Victoria having daylight savings time and Queensland... not. Australian Pay TV providers also includes feeds for Free-to-Air channels as well and each state gets the feed from their local version (mostly just different news). But SBS only has a single, nationwide version and the Pay TV feed is set so Queenslanders with Pay TV can get it an hour earlier than normal or turn over and get the normal times from the local transmitter. As commercial TV markets overlap on the Gold Coast (as it can receive stations from both Brisbane and Northern New South Wales), this used to make the Brisbane station an hour timeshifted during the summer compared to the regional stations, until people complained that it broke watershed laws. Now, the regional stations have to delay their Gold Coast transmitters by an hour.
- British station Dave calls its +1 channel "Dave Ja Vu". Why a channel that shows almost nothing but whole series of Top Gear, Have I Got News for You and QI back-to-back, frequently showing the same episodes twice in the same 24-hour period thanks to British Brevity, feels the need for one of these is anyone's guess.
- British satellite TV station DMAX is currently up to four channels - DMAX, DMAX+1, DMAX+1.5, and DMAX+2.
- Canadian sports broadcaster TSN used regulatory loopholes surrounding such services to create the digital channel TSN2, which primarily timeshifed programming from TSN (such as the night's major sporting event), but could also air a limited amount of alternate content daily. As such, TSN2 would also be used to off-load other live events that couldn't be shown on the main TSN channel due to other commitments. While competing sports networks complained that TSN was abusing this ability to create extra advertising revenue, the CRTC (like the FCC, except that they also regulate specialty services too) decided there was no wrongdoing, and then decided to reduce exclusivity restrictions for sports and news channels, and amending TSN's license to simply say it can operate multiple feeds without much restriction. Following the change, TSN2's schedule began to become more autonomous from its flagship, much like its American equivalent ESPN2.
- ESPN often does the same thing as TSN, often running shortened (well, two hour block) versions of the night's big game on the network around 2 AM or so on ESPN 2, giving night owls the phrase "Due to time constraints, we'll move ahead to further action."
- ESPN's practices have now moved to regional sports networks, allowing second shifters to catch their games.
- Most of the networks aimed at kids in the U.S (Cartoon Network, Nickelodeon, Disney Channel) have a East and West coast channel.
- Starting originally as east/west coast feeds, but always featured as separate channels on Satellite and increasingly Cable Networks, premium movie channels like HBO, Showtime, and Cinemax have several channels now with a repeat 3 hours later -W channel (HBOW, Show-West, etc)
- Pro TV Chișinău is the Moldova sister-channel of Romanian Pro TV. The timeshift is actually incidental and the result of poor timing of commercial times, but can act as this with a maximum difference of about 15 minutes. The irony goes further that there are obvious awkward attempts to put the shows in perfect sync, but it rarely works out.
- The UK station Channel 4 has a basic timeshift channel, Channel 4+1, but also Four Seven, which is a kind of non-linear timeshift channel, showing the same programmes but in a different order and with its own presentation between.
- In Portugal, this is not the responsibility of the channels themselves, but of the cable/IPTV/whatever companies. 4 of the 5 cable companies (i.e. all except Cabovisão) have this kind of functionality, and they allow us to see the program from the (theoretical) beginning, even when the program is still on. Its called Gravações Automáticas (Automatic Recordings) in Meo and you can see the programs a whopping 7 days after the first broadcast of the show (including when the show is still on). In Vodafone, it's also called Gravações Automáticas when the first broadcast of the show ended and it also allows you to see the show after 7 days, but it's called Restart TV when the show is still on. In ZON, it's called Timewarp when the show has ended and you can still see the show for seven days and Restart TV when the show is still on. In Optimus Clix, it's called Restart TV both when the show is on and already ended, and it works when the show is 2 days or less old. The problem is when the TV channels aren't that punctual... Oh, and sometimes not all channels are avaliable (but neither one of these is those channels we see, so... - for the most part, anyway).
- Some local stations, such as WGN in Chicago, WTVF in Nashville and WWL in New Orleans, run separate cable or digital over-the-air channels which are devoted to running the latest newscast on an automated loop to allow viewers to catch up. In fact, many station websites often now use their 'live streaming' video channels to loop a newscast when they aren't live. In the past the only way to rewatch a newscast was often a late-night replay of the late news; this still occurs on some stations but has become more rare as time has gone on.
