Abstract
A method for shaping video streams applied to a first set-up box collects watching history of user and previous playback information and analyzes same to generate multiple bitrate combinations. First and second stream buffers of two respective video streams are initialized according to the bitrate combinations and the history. First and second image chunks of the first and second video streams are downloaded and stored in the first and second stream buffers and displayed in a first display device connecting to the first set-up box. Buffer ratios are determined and when the buffer ratio of the first is equal to the second, image chunks are continued to be downloaded from the second. If the buffer ratio of the first is not equal to the second, the video stream with smaller stream buffer ratio is selected for continuing to download the image chunks.
