Abstract
Abstract An identifier-adding unit adds an identifier to sending tele-writing information to be sent from the first tele-wiring system to a second tele-writing system via telecommunication. The identifier is used to identify a document to be processed as a result of a tele-writing operation being specified. This causes a second picture displayed on the second tele-wiring system to be affected, if appropriate, according to the sending tele-writing information. The information corresponds to a first tele-writing operation for affecting a first picture displayed on the first tele-writing system. A document identifying unit identifies, using an identifier added to received tele-writing information sent from the second tele-writing system to the first tele-writing system, a corresponding document to be processed as a result of the tele-writing operation being specified.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
226 words
A tele-writing system comprising: identifier-adding means for adding an identifier to sending tele-writing information to be sent from the first tele-wiring system to a second tele-writing system via telecommunication, said identifier being used to identify a document to be processed as a result of tele-writing operation being specified, which causes a second picture displayed on said second tele-writing system to be affected according to said sending tele-writing system; document identifying means for identifying, using an identifier added to received tele-writing information sent from said second tele-writing system to said first tele-writing system, a corresponding document to be processed as a result of said tele-writing operation being specified; sequential-number adding means for adding a sequential number to said sending tele-writing information, said sequential number being either incremented or decremented, as is appropriate, depending on which kind of tele-writing operation is specified on said first tele-writing system; comparing means for comparing said sequential number with a sequential number added to said received tele-writing information; sequential-number updating means for either incrementing or decrementing said sequential number as is appropriate according to the result of the comparison specified by said comparing means; difference detecting means for detecting a difference between said first and second pictures based on said result of said comparison performed by said comparing means; and correcting means for correcting said difference detected by said difference detecting means.
Claim 2
Dependent Claim
226 words
A tele-writing system comprising: identifier-adding means for adding an identifier to sending tele-writing information to be sent from the first tele-wiring system to a second tele-writing system via telecommunication, said identifier being used to identify a document to be processed as a result of tele-writing operation being specified, which causes a second picture displayed on said second tele-writing system to be affected according to said sending tele-writing system; document identifying means for identifying, using an identifier added to received tele-writing information sent from said second tele-writing system to said first tele-writing system, a corresponding document to be processed as a result of said tele-writing operation being specified; sequential-number adding means for adding a sequential number to said sending tele-writing information, said sequential number being either incremented or decremented, as is appropriate, depending on which kind of tele-writing operation is specified on said first tele-writing system; comparing means for comparing said sequential number with a sequential number added to said received tele-writing information; sequential-number updating means for either incrementing or decrementing said sequential number as is appropriate according to the result of the comparison specified by said comparing means; difference detecting means for detecting a difference between said first and second pictures based on said result of said comparison performed by said comparing means; and correcting means for correcting said difference detected by said difference detecting means.
Claim 3
Dependent Claim
48 words
The tele-writing system according to claim 1, wherein said correcting means comprises reaffecting means for causing said first picture that has been once affected by a first tele-writing operation to be affected again by a second tele-writing operation which is the same operation as said first tele-wiring operation.
Claim 4
Dependent Claim
166 words
A tele-writing system comprising: identifier-adding means for adding an identifier to sending tele-writing information to be sent from the first tele-wiring system to a second tele-writing system via telecommunication, said identifier being used to identify a document to be processed as a result of tele-writing operation being specified, which causes a second picture displayed on said second tele-writing system to be affected according to said sending tele-writing information, which information corresponds to a first tele-writing operation for affecting a first picture displayed on said first tele-writing system; document identifying means for identifying, using an identifier added to received tele-writing information sent from said second tele-writing system to said first tele-writing system, a corresponding document to be processed as a result of said tele-writing operation being specified; and examining means for examining contents of said received tele-writing information along and also examining the combination between said received and sending tele-writing information so as to determine how said first tele-writing system processes said received and sending tele-writing information.
Claim 5
Dependent Claim
166 words
A tele-writing system comprising: identifier-adding means for adding an identifier to sending tele-writing information to be sent from the first tele-wiring system to a second tele-writing system via telecommunication, said identifier being used to identify a document to be processed as a result of tele-writing operation being specified, which causes a second picture displayed on said second tele-writing system to be affected according to said sending tele-writing information, which information corresponds to a first tele-writing operation for affecting a first picture displayed on said first tele-writing system; document identifying means for identifying, using an identifier added to received tele-writing information sent from said second tele-writing system to said first tele-writing system, a corresponding document to be processed as a result of said tele-writing operation being specified; and examining means for examining contents of said received tele-writing information along and also examining the combination between said received and sending tele-writing information so as to determine how said first tele-writing system processes said received and sending tele-writing information.
