Abstract
Abstract As an MPEG stream is playing out, e.g., from an MO drive or other source, an edit point is indicated. When the edit point is indicated, an entry is made into a computer readable table associated with the MPEG stream. The entry includes a first value representative of a presentation time stamp associated with a picture in the MPEG stream. The entry also includes a second value representative of a storage location on a media on which the MPEG stream being played out is stored.
