Abstract

Communication equipment comprises a communication section 3 performing communication with other equipment via a public line, a local area network, or an infrared communication network, a resource information storing section 5 storing what format data equipment can handle, a data storing section 6 storing data to be transmitted, a data conversion section 7 converting data so that the other party of communication can interpret it, a conversion table 8 storing whether currently held data can be converted to a form that the other party of communication can interpret, a conversion- means storing section 9 storing actual conversion means, and a negotiation section 10 knowing what the resource information of equipment of the other part is.

Claims

1. Communication equipment for transmitting and receiving information including all or some of characters, images, figures, voice, music data and digitized data, comprising:

resource information storing means for storing information on a resource comprising hardware and software for processing data;

negotiation means for communicating with other communication equipment on a receiving side to judge if said other communication equipment on the receiving side has the same resource; and

conversion means which, when said other communication equipment on the receiving side does not have the same resource, performs data conversion, based on a conversion table stating conversion means for converting data to be transmitted to data that said other communication equipment on the receiving side can process,

wherein the data to be transmitted includes a plurality of data groups each having information on data format thereof and said data groups include different data formats, said negotiation means judging if each of said data groups is convertible based on said information on the resource of said other communication equipment on the receiving side or said information on data format in the data to be transmitted, and said conversion means converting data groups in said plurality of data groups based on the result of the judgement on the convertibility.

2. A communication equipment as set forth in claim 1, further comprising:

performance evaluation value storing means for storing a performance evaluation value representative of calculation performance of said communication equipment; and

performance comparing means for comparing said performance evaluation value of said communication equipment with a performance evaluation value of said other communication equipment on the receiving side; and

wherein said performance evaluation value of said communication equipment and said performance evaluation value of said other communication equipment on the receiving side are compared and said data conversion is performed with one of said communication equipment which is superior in performance evaluation value.

3. A communication equipment as set forth in claim 1, further comprising:

original-address storing means for storing where original data exists with respect to each data; and

original-address adding means for adding, at the time of communication, information on where original data exists; and

wherein, when said original data is desired to be obtained at said other communication equipment on the receiving side, said original data is obtained from the other communication equipment having said original data, based on an instruction from a user.

4. A communication equipment as set forth in claim 1, wherein said conversion table and said resource information storing means are a writable medium.

5. A communication equipment as set forth in claim 1, further comprising:

conversion requesting means for requesting data conversion of a third communication equipment differing from said communication equipment and said other communication equipment on the receiving side; and

conversion accepting means for accepting conversion from the other communication equipment; and

wherein, when data cannot be converted at said communication equipment to a form that said other communication equipment on the receiving side can process, data conversion is requested of said third communication equipment and the converted data is sent to said other communication equipment on the receiving side.

6. A communication equipment as set forth in claim 1, further comprising:

communication time estimating means for estimating a communication time needed for data transmission for each of various data conversions;

display means for displaying an evaluation time of said communication time for each said data conversion; and

selection means for selecting an arbitrary method based on information on the kind of said data conversion and said communication time displayed on the said display means.

7. A communication equipment as set forth in claim 1, further comprising:

output-information storing means for storing information including software for processing current data to be transmitted, and

wherein, when said other communication equipment does not have said information including software for processing current data but communication equipment on a sending side has said information, said information is transmitted together with said current data.

8. A communication equipment as set forth in claim 1, wherein each of data groups includes said information on data format at the top thereof.

9. Terminal equipment for transmitting and receiving a message consisting of data such as voice, characters, and figures, and a code controlling an operation of a terminal, comprising:

absence judging means which, when a message is received, judges that a user is absent;

transmitting means which, when the user is judged to be absent by said absence judging means, automatically transmits an absence message to a sender of the received message, said absence message including a code for controlling an output of a terminal of said sender;

code information control means for interpreting said code when said absence message including said code is received, and for controlling said terminal equipment in accordance with the interpretation of said code;

secondary storage means for storing transmission messages, reception messages, a history of transmission and receptions, and data characteristic to senders; and

display means for displaying said history stored in said secondary storage means as character information.

10. A terminal equipment as set forth in claim 9, where said code information control means which, when the user selects the other party of transmission from said history displayed on said display means, provides control so that a message is transmitted by use of said data stored in said secondary storage means.

11. A terminal equipment as set forth in claim 9, further comprising fixed-pattern storage means for storing a plurality of patterns of said absence message.

12. A terminal equipment as set forth in claim 9, further comprising message editing means for a user to make said absence message.

13. A terminal equipment as set forth in claim 10, where said code information control means receives a message including a code requesting communication and provides control so that communication with a sender is performed when the user selects performing communication.

14. A terminal equipment as set forth in claim 10, where said code information control means provides control so that when a message is displayed, a message including a code requesting communication is displayed on said display means and when the user selects performing communication, communication with a sender is performed.

15. A terminal equipment as set forth in claim 9, where said secondary storage means stores data, which the user inputs, in the same data form as said absence message.

16. A terminal equipment as set forth in claim 9, wherein said code includes a code for controlling the terminal of said sender to request a reply to said absence message.
