To produce a paused MPEG coded video stream from an original MPEG coded video stream, an I frame is extracted from the original stream, and a Group of Pictures for a “pause” (a pause GOP) is constructed containing the extracted I frame, some “frozen” frames, and padding. Each “frozen” frame is a P frame that repeats the I frame. When a pause is requested in the original stream, a seamless transition is made from the I frame to the pause GOP, and the pause GOP is played in a loop until a resume is requested. To resume, the pause GOP is completed and a seamless transition is made to continue in the original stream from the I frame where the pause had begun.
