Abstract
Abstract A video conferencing system, wherein multiple parties at different locations can view, and modify, a common image on their computer displays. The invention also provides a video camera at each computer, which takes a video picture of each party. The invention distributes data to all computers involved in the conference from which each computer can generate a display containing the common image, the modifications, and the video pictures.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A computer system, comprising: a) multiple remote computers at different locations, each having a display; b) substantially identical remote program means, running on each remote computer, for communicating with one host application program running on a host computer; and c) means for allowing a user of each remote computer to simultaneously: i) hold a video conference; and ii) operate the remote program means executing on the remote computer, the remote program enabling the remote computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the remote computer; and 4) communication between the remote program and the host program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 2
Dependent Claim
128 words
A computer system, comprising: a) multiple remote computers at different locations, each having a display; b) substantially identical remote program means, running on each remote computer, for communicating with one host application program running on a host computer; and c) means for allowing a user of each remote computer to simultaneously: i) hold a video conference; and ii) operate the remote program means executing on the remote computer, the remote program enabling the remote computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the remote computer; and 4) communication between the remote program and the host program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 3
Dependent Claim
33 words
A system according to claim 1 in which communication among the computers can by accomplished by two data channels having a total capacity not exceeding 128,000 bits per second in both directions, simultaneously.
Claim 4
Dependent Claim
133 words
A computer system, comprising: a) two or more computers at different locations, each capable of running a substantially identical message-driven, multi-tasking, operating environment; b) substantially identical program means, running on each computer, for communicating with one host application program running on a host computer; and c) means for allowing users of the computers to simultaneously: i) hold a video conference; and ii) operate the substantially identical program means executing on the computer, the program means enabling the remote computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the remote computer; and 4) communicate between the remote program and the host application program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 5
Dependent Claim
133 words
A computer system, comprising: a) two or more computers at different locations, each capable of running a substantially identical message-driven, multi-tasking, operating environment; b) substantially identical program means, running on each computer, for communicating with one host application program running on a host computer; and c) means for allowing users of the computers to simultaneously: i) hold a video conference; and ii) operate the substantially identical program means executing on the computer, the program means enabling the remote computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the remote computer; and 4) communicate between the remote program and the host application program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 6
Dependent Claim
148 words
A kit for connection to a user's computer, comprising: a) a video camera; b) a capture card for receiving i) video data from the video camera, and ii) video data from a communication channel; and converting both video data into forms usable by the computer; c) remote program means for communicating with one host application program running on a host computer; and d) program means for allowing a user of the computer to simultaneously: i) hold a video conference with another computer; and ii) operate the remote program means, the remote program means enabling the computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the computer; and 4) communicate between the remote program and the host program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 7
Dependent Claim
148 words
A kit for connection to a user's computer, comprising: a) a video camera; b) a capture card for receiving i) video data from the video camera, and ii) video data from a communication channel; and converting both video data into forms usable by the computer; c) remote program means for communicating with one host application program running on a host computer; and d) program means for allowing a user of the computer to simultaneously: i) hold a video conference with another computer; and ii) operate the remote program means, the remote program means enabling the computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the computer; and 4) communicate between the remote program and the host program to selectively replicate the annotation images on the displays of the other remote computers.
Claim 8
Independent Claim
151 words
A system for communicating with other computers by a communication channel, comprising: a) a computer equipped with i) a message-driven, multi-tasking, operating environment; ii) video camera means for feeding the computer with data representing a visual image; and iii) means for interfacing with the communication channel; b) remote program means for communicating with one host application program running on a host computer; and c) program means for allowing a user of the computer to simultaneously: i) hold a video conference with other computers so equipped; and ii) operate the remote program means, the remote program means enabling the computer to: 1) communicate with the host application program; 2) provide program input to the host application program; 3) draw annotation images on the display of the computer; and 4) communicate between the remote program and the host program to selectively replicate the annotation images on the displays of the other remote computers.
