20. The apparatus of claim 16 , wherein the segment length of each semantic event varies according to an event type of each semantic event.
16. A processing apparatus, for processing a sports video, comprising: an analyzing block, for analyzing the sports video to detect at least one semantic event each of which is associated with a segment length; an operating block, for assigning a segment length to the at least one semantic event according to importance of a corresponding event; a first processing block, for extracting a scene segment associated with the at least one semantic event out of the sports video according to the segment length; and a second processing block, coupled to the analyzing device, for generating a summarized video according to the detected at least one semantic event; wherein the segment length of each semantic event varies according to importance and weight of each semantic event and varies according to a context analysis result showing the relative importance of each semantic event comparing to its prior and subsequent events throughout the sports video, and the first processing block further generates the semantic event further according to at least one of base bag, score, and out in a score board region.
