Catch-up is a type of VOD (Video On Demand). Catch-up can often be considered of recording your TV which you can watch later. Most IPTV services provide some sort of catch-up option, with a limited timeline.
For example on channel X the catch-up option is active for 48 hours, it means you can watch all programs on this channel in past 2 days anytime you want. If you missed your favorite series or football match which showed last night, you can see it the channel history catch-up.
Technically, you can “rewind” what was a straight broadcast and then start viewing from any point. After viewing your missed TV program, you might be capable to jump over to another TV program.
Recently beside MAG boxes catch-up available on some applications like IPTV Smarters.
Note that catch-up needs large amount of storage to record previous programs, so IPTV providers only can activate it for some special channels in a limited time (usually 24 or 48 hours).
