Low bandwidth television
First Claim
1. A production module authoring system, for use in a low bandwidth video system, comprising:
- a computer having a display screen, memory, image files, video files, and audio files; and
a software application, residing in said memory, which presents a graphical user interface on said display screen that allows a user to use point-and-click operations to build a production module for use in said low bandwidth video system, said software application comprising;
a director module residing in said memory; and
said a production module, including a script module, an image module, an audio module, and a new effects module;
wherein said director module (1) uses said image module, new effects module, and instructions in said script module to compute a series of real-time screen transitions; and
(2) combines said real-time screen transitions with associated audio to render high quality digital video on said display screen.

Abstract
The present invention is concerned with client-side production in a personal computer environment of low bandwidth images and audio. A series of low bandwidth still images along with a “script” and audio data is sent over a network in a client/server architecture or is read from a compact disk or other memory. A “director” module residing in a client personal computer uses the “script” to tell the computer how to execute a sequence of “moves” on the still images. These moves include cuts, dissolves, fades, wipes, focuses, flying planes and digital video effects such as push and pull. Moves within a still image occur in real time, and are relatively smooth and continuous as compared to prior art network video. Low bandwidth is achieved because most of the production is done at the client location without relying upon slow, bandwidth-limited downloading of conventional network video formats.
