Seeking help to Find the name of a TV show

Hi all,

This story is about two siblings (brother and sister) trying to find their farther who went missing during some time traveling. The sister is on a wheel chair.

 

They were investigating some art-effects from the past which are related to some great stories.

 Or for the disappearing of their farther I do not know for sure….

 

By putting them to a big TV screen on their house they realized once the touched the art-effect through the screen or through the hologram they can time travel to the past time which that art-effect belongs too. And also they get to act the character related to the story.

 

Only he or she goes alone once at the time so that the other one can guide him or her through the timeline of the story by history lessons related to the character he or she was given.

 

If they are to leave that timeline and return to the physical world, the character has to find that art-effect through some sort of a quest or series of test and physically acquire it or touch it.

 

To complete this quest or test one who stays behind must help the other by telling how to go forward in the story.

 

I got some great answers for my previous questions and solutions hope this one will get sorted out soon too.

 

Thank you.
