Patent ID: 7383565

Claim:
A directing process for use in sending a trick-mode video stream from a video server which comprises—a) a digital computer that is coupled to a semiconductor memory which stores a video, and b) a network interface circuit which couples said computer to a viewer network; said process being performed by said computer and including the steps of: receiving a request, from said network interface circuit, for directions on how to generate a respective portion of said trick-mode video stream; determining that said respective portion of said trick-mode video stream needs to be generated from a continuous segment of said video in said memory which includes—1) a picture and 2) selected items which are spaced-apart within said continuous segment and which need to be modified before being sent in said trick-mode video stream; building, in a part of said memory separated from said continuous segment of said video, not the entire respective portion of said trick-mode video stream but only modified items which correspond to said selected items with their modifications; and, sending to said network interface circuit, said directions in a form which direct said network interface circuit to generate said respective portion of said trick-mode video stream by interleaving said modified items built by said building step with all portions of said continuous segment of said video in said memory that are not said selected items.
