Abstract
A system and method for editing a bitstream is provided. A first segment is cut from a first bitstream and a second segment is cut from a second bitstream. In cutting the segments from the bitstreams, first and last GOPs in the segments can be cut between frames in the GOP. The number of frames of the broken GOP is then compared to a pre-determined threshold value. If the number of frames of the broken GOP is less than or equal to the threshold value, the broken GOP is combined with a neighboring GOP. Therefore, the newly created GOP is longer than the standard size regular GOP. However, if the number of frames in the broken GOP is greater than the threshold value, a new GOP is created with the frames of the broken GOP. Therefore, the newly created GOP is shorter than the standard size regular GOP.
