With Digital TV broadcasting (DTV) there are hundereds of channels available. Among them some programs can match our preferences, but the user has to search from a list and find them. Moreover, once he finds out a program of his interest he has to consider the time he has available to watch at it. If it is not enough (for example a movie lasting 2 hours, but he just has 1 hour and half available ) he needs to continue searching for another program, checking for its duration and eventually repeating the search until a program fitting his time window is found. It would be helpful to have a system which prompts the user for a list of programs matching his preferences and fitting into his boxed time frame.

Only the programs fitting that window will be presented in the selection list. There are different options which can be made available by the time selection algorithm:
1- Choose only programs starting and ending inside the user selected boxed time window
2- Choose also programs started outside (before) the boxed time window but ending inside the boxed time window
3- Like point 2 but not started more that n-minutes before the current time.
4- Choose also programs starting inside the boxed time window and ending outside (after) the boxed time window.
4a- Like point 4 but ending no more than n-minutes after,
4b- A mix combination of options 2,3,4 and 5.
