技術摘要 / Our Technology: |
本發明有關於一種可根據頻寬速率調整影片內容的方法,其中,從影片的鏡頭中識別出複數個目標鏡頭及非目標鏡頭,目標鏡頭之影片畫面中分解出一背景及至少一前景物件,本發明的方法提供複數個頻寬階層,並選定其中一頻寬階層,根據所選定的頻寬階層選擇至少一前景物件貼著在背景上,以取得至少一重組的目標鏡頭,根據所選定的頻寬階層組合重組的目標鏡頭、非目標鏡頭或其他重組的目標鏡頭為一重組的影片單元,藉此,本發明係可根據頻寬速率調整影片內容,以提供不同的影片串流大小,如此,在低頻寬速率下,觀賞者仍可觀賞到高畫質的影片。
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.
