Tennis Video 2.0
A new presentation method containing video analysis and rendering tools for enriching sports videos with properties of the Structure, Interactivity, and Scalability.
Abstract
Tennis videos are used as an example for the implementation of a viewing program called as Tennis Video 2.0. For the methods in video analysis, background generation by considering the pixels in temporal and spatial distribution is proposed; fore- ground segmentation combining automatic trimap generation and matting model is proposed. To provide more functions in watching videos, the rendering flow of video contents and the semantic Scalability are proposed. With the new analysis and rendering tools, the presentation of sports videos has three prop- erties—Structure, Interactivity, and Scalability. The experiments show that several broadcasting game videos are employed to evaluate the robustness and performance of the proposed system. For user study, 20 evaluators highly identify that Tennis Video 2.0 is a new presentation of sports videos and give people better viewing experience.

Abstract
A method for scaling video content based on bandwidth rate is disclosed. Wherein, a plurality of target shots and non-target shots are recognized from shots of a video. A background and at least one foreground object are separated from the video frame of the target shot. The present invention method provides a plurality of bandwidth levels, and one among them is selected in advance. At least one foreground object is selected and pasted on the background based on the selected bandwidth level, so as to obtain at least one recombined target shot. The recombined target shot, the non-target shot or other recombined target shot can be merged to form a recombined video unit based on the selected bandwidth level. Therefore, the present invention proposes video content of scalability based on bandwidth rate to provide the different video bit-stream size, so that viewer can get the high quality video under the lower bandwidth rate.
