Patent ID: 8189994

Claim:
A device for giving importance information according to a video operation history comprising an interest video searching operation block detector which includes: a video operator for performing a video operation in response to a video operation request which includes fast forwarding, rewinding, and replaying performed by a user; a preview log generator coupled to the video operator and generating a video operation history according to the video operation performed by the video operator; an interest video searching operation block detector coupled to the preview log generator and detecting the video searching operation block performed by the user from the preview log generated by the preview log generator until the interest video section is reached; a user interest section detector coupled to the interest video searching operation block detector and detecting a user interest section by eliminating a replay section contained in the interest video searching operation block detected by the interest video searching operation block detector from a plurality of replay sections contained in the preview log; and an important information giver coupled to the interest section detector and giving importance information to the user interest section detected by the user interest section detector; wherein the interest video searching operation block detector further includes: a minimum searching operation block detector for determining the operations having oppositely directed video operations overlapped with each other with respect to time among said fast forwarding, rewinding and replaying as the interest video searching operation block from a preview log as a video operation history of a user, and further detecting a minimum searching operation block of a minimum unit which exists in an interest video searching operation block; and a searching operation block setter coupled to the minimum searching operation block detection unit and having pattern setting unit for setting the interest video searching operation block through determination with respect to an operation previous and subsequent to the detected minimum searching operation block as a base point based on a feature of the interest video searching operation block.
