Patent ID: 8074163

Claim:
An information processing apparatus comprising: means for storing a pre-set processing unit on which is pasted object information captured by a clipping or copying operation and having different attributes and time information in association with each other and difference information indicating only a difference in the pre-set processing unit each time the pre-set processing unit is modified and a date and time corresponding to each modification, wherein the object information pasted onto the pre-set processing unit includes at least one of audio data and video data and the pre-set processing unit includes a button used to control reproduction of the at least one of the audio data and video data; means for regenerating said pre-set processing unit in a state associated with a desired date and time based on said time information by retrieving the stored difference information corresponding to the desired date and time; and rotatable operating means, wherein said means for regenerating controls a display state of the pre-set processing unit to show incremental changes in the pre-set processing unit in a first time direction based on a rotational actuation of said operating means in a first direction, and controls the display state of the pre-set processing unit to show incremental changes in the pre-set processing unit in a second time direction based on a rotational actuation of said operating means in a second direction, and said means for regenerating sets a color of an edge of the pre-set processing unit to a first color when that the pre-set processing unit is a past pre-set processing unit that can not be corrected regardless of whether the pre-set processing unit is being viewed in a past, present or future mode, and a second color when the pre-set processing unit is a future or present pre-set processing unit that is not currently correctable but may be made correctable by viewing the pre-set processing unit in one of the present or future modes.
