Converting non-temporal based compressed image data to temporal based compressed image data

Abstract From the Canadian patent

The application relates to creating an MPEG file from non-temporal based compressed image data that are stored on randomly accessible storage and edited on a nonlinear video editor to create a video program (fig.1 10). The , editor generates information indicating the complexity of portions of image data simultaneously with storing and/or editing of the image data (fig.1 10). , The information is accessed to determined MPEG compression quality levels for groups of pictures of the image data based upon information (fig.1 12). The , groups of pictures of non-temporal based compressed image data are converted into MPEG compressed data using the respective quality levels (fig.1 12). , Also …
