Embodiment

A kind of device of implementing diapositive return-play, it comprises the historical record memory module, and it is used for storing successively and writing down the lantern slide record of being play, and in addition, it also comprises:

The rollback trigger module, it is used to receive user's triggering command, and excites following rollback execution module;

The rollback memory module, it is used for storing the lantern slide playing record of back off procedure, and its inside has only a lantern slide playing record at most, and its original state is empty;

Module is set, and it is used for historical record memory module or rollback memory module put in current lantern slide record;

The rollback execution module, it is used for judging the state of rollback memory module when receiving user's rollback execution command, and carries out different playback action according to this state.

As long as current lantern slide playing changes, module is set all the broadcast record of lantern slide can be recorded into the historical record memory module successively.That is to say, the same with existing historical record memory module, wherein write down the lantern slide record of all playing all the time successively, no matter carry out " page up ", " following one page ", " page or leaf of watching in the past " or " retreating ".Different with the historical record memory module is that the rollback memory module is at most only stored a lantern slide playing record.

Above-mentioned rollback trigger module can be finally realized with the form of rollback menu or rollback button.Particular location as for menu and button is then set up on their own when programming by the programmer, and this is not a core of the present invention.

The present invention has also disclosed a kind of method of implementing diapositive return-play, and referring to Fig. 3, it comprises the steps:
