Abstract

An interactive video communication system, includes a bi-directional communication channel; a central information facility connected to the communication channel; an interactive information database associated with the central information facility containing video programming material with imbedded references to high resolution digital images selectable by a system user; a data base containing the referenced high resolution digital images; a printer processor for converting a viewer selected high resolution image to control signals for printing the image on a system user'"'"'s dumb color printer; and a population of system users, each having a transceiver connected to the communication channel, a video display connected to the transceiver for displaying video programming material received from the central information facility, a dumb color printer for printing high resolution color images received by the transceiver from the central information facility, and a controller for selecting high resolution digital images referenced in the programming material.

Claims

1. An interactive video communication system, comprising:

a) a bi-directional communication channel;

b) a central information facility connected to the communication channel;

c) an interactive information database associated with the central information facility containing relatively low resolution video programming material with imbedded references to relatively high resolution color digital images selectable by a system user;

d) a data base associated with the central information facility containing the referenced relatively high resolution color digital images;

e) a printer processor associated with the central information facility for converting a viewer selected relatively high resolution color digital image to control signals for printing the image on a system user'"'"'s dumb color printer; and

f) a population of system users, each having a transceiver connected to the communication channel, a video display connected to the transceiver for displaying the relatively low resolution video programming material received from the central information facility, a dumb color printer for printing the relatively high resolution color images received by the transceiver from the central information facility, and a controller for selecting high resolution digital images referenced in the programming material.

2. The interactive video communication system claimed in claim 1, wherein the dumb printer comprises:

a) a control processor for controlling the printer;

b) a paper handling mechanism;

c) a digital to analog converter for receiving digital print signals from the control processor and producing analog print signals; and

d) a print head connected to the digital to analog converter.

3. The interactive video communication system claimed in claim 2, wherein the dumb printer further comprises a data buffer.

4. The interactive video communication system claimed in claim 1, wherein the data base of referenced high resolution digital images is located remotely from the central information facility.

5. The interactive video communication system claimed in claim 1, wherein the printer processor includes a table containing characteristics of the system user'"'"'s printers.
