TimeShift feature provides users with ability to record stream of current IPTV channel in order to listen to / watch the recording afterwards. TimeShift recording is saved to the STB local storage known as memory buffer. Recorded audio  / video fragments can be played back during current recording or after its termination, being started from either time position within the record. To select starting time position of playback, forward / rewind feature is used.

TimeShift settings

TimeShift feature configuring is made in TimeShift section of Settings.
In addition, to use TimeShift feature, make sure that Storages access mode option has been set to 'full access' (see System settings / Advanced settings / More).

Marking channels that are allowed to use TimeShift

1. record / <File name> / <Creation date of recording> - directory that contains text files named <Start time of recording >.tspinf which are links to media files (see item 2)

2. record / <IPTV channel> / <Creation date of recording> . tsp - directory containing media files named <Start time of recording>.tsp
