Abstract
A hybrid format for representing a video lesson which is transported from a first location to a second location across a communication channel includes a first item having a first format type and a second item having a second format type. The first format type is different from said second format type, yet the lesson can be played to the student as if it were a single contiguous data item. As such, efficiencies can be obtained in storage and transfer.
