Abstract: A terminal device includes: an application processor that processes a started application program; an operation lock determination section that determines whether to start operation lock while processing the application program; and an operation lock processor that determines whether input operation information matches operation lock information in a case where the operation lock determination section determines to start the operation lock, the operation lock information indicating an operation to be restricted while processing the started application program, the operation lock processor restricting an operation corresponding with the input operation information in a case where the input operation information matches the operation lock information.

Abstract: The broadcast receiver has a key input unit that inputs user instruction information concerning broadcast reception, such as a channel setting by the user and information concerning selection of a broadcasting station or program; a historical switching information holding unit that accumulates switching information, which includes such information as the position and time when the channel was switched and the channels before and after switching the channel; and a switching condition search unit that searches the historical switching information holding unit to determine whether or not there is user instruction information input through the key input unit or switching information matching the position information and time information for when the user instruction information was input through the key input unit, and if any, extracts the appropriate switching information to generate switching condition information.
