Abstract
A method of integrating audio information and video information, with a single pass is disclosed. In the system of the present invention, a first pass is made through a collection of audio and video information to determine certain information that will be needed to create an integrate bitstream. Specifically, a length in time of each video object unit is determined and a size of each video object unit is determined. This information is used to construct a video object unit table that will be used to create video object units. The video object unit table contains navigation information needed to navigate a DVD. The navigation information is generated from length in time of each video object unit and size of each video object unit. Once video object unit table is created, the system proceeds to recording an output file that contains integrated audio information, video information, and navigation information using.
