Abstract

Disclosed is a method for interchanging contents information and a system for interchanging contents information. A loop that a receiving side CL1 sends a request signal CL1a carrying position data pd to a sending side SV1 through a communication system NT, the sending side SV1 sends back contents information corresponding thereto as a sending signal SV1a, and the receiving side CL1 displays the signal is repetitively updated and performed at a high frequency by repetitively updating and sending the position data pd at a high frequency. Since the achievable frequency of repetitive updating and performing the loop varies by the combination of receiving side CL1, communication system NT, and sending side SV1, the achievable maximum frequency mxfQ for each loop is determined from a given table or by actual measurement. A standard frequency stfQ which does not exceed the thus determined frequency is set, the processes along the loop are performed at the standard frequency stfQ or a lower frequency. As a result, power consumption is reduced and communication load is mitigated.

Claims

1. A method for interchanging information in which a receiving side, which receives information, sends to a sending side, which keeps said information, a request for transmission of said information through a communication system, said sending side, in response to said request, sends said receiving side said information through said communication system, and said receiving side receives said information which has been sent and displays said information in the form of an image with or without voice, on the assumption that generation of said request in said receiving side is a preliminary processing step and said displaying at said receiving side is a final processing step, there is at least one intermediate processing step in at least any of said receiving side, said sending side, and said communication system, between said preliminary processing step and said final processing step, the route along which an ensuing processing step is executed by using the result of a preceding processing step constitutes a loop, and the number of times for updating processing within a unit time is a frequency, wherein said method comprises:

repeatedly updating said request and said loop, and

keeping the frequency of at least one step before the preceding processing step from said final stage processing step lower than a permissible frequency for which said final stage processing step has been confirmed.

2. The method for interchanging information according to claim 1, which characterized in that the frequency at which the final stage processing step can be repeatedly updated is confirmed by actual measurement by said receiving side.

3. The method for interchanging information according to claim 1, which is characterized in that said request has arbitrary position data and said information is contents information possessing said image with or without voice associated with said information, with said image being so constructed as to be displayed in frame units, and the frequency at which the final stage processing step is repeated is the frequency at which the image of said contents information is updated.

4. The method for interchanging information according to claim 3, which is characterized in that said position data is one which is selected from (1) positioning data which is generated intermittently by satellite or radio positioning or (2) position data obtained by interpolation of the amount of movement (which is calculated from the moving speed and moving time of the receiving side) and said positioning data obtained most recently, said position data being generated while said positioning data is not generated.

5. The method for interchanging information according to claim 1, which is characterized in that said request has arbitrary position data and viewing direction data indicating an arbitrary direction as said arbitrary position and said information is contents information possessing said image with or without voice associated with said position data and said viewing direction data, with said image being so constructed as to be displayed in frame units, and the frequency at which the final stage processing is repeated is the frequency at which the image of said contents information is updated.

6. The method for interchanging information according to claim 1, which is characterized in that charge is levied based on the amount of request information sent or the amount of information transmitted.

7. A method for interchanging information in which a receiving side, which receives arbitrary information, sends to a sending side, which keeps said information, a request for transmission of said information through a communication system, said sending side, in response to said request, sends said receiving side the information through said communication system, and said receiving side receives said information which has been sent and displays said information in the form of an image with or without voice, on the assumption that generation of said request in said receiving side is a preliminary processing step and said displaying in said receiving side is a final processing step, there is at least one intermediate processing step in at least any of said receiving side, said sending side, and said communication system, between said preliminary processing step and said final processing step, the route along which an ensuing processing step is executed by using the result of a preceding processing step constitutes a loop, and the number of times for said loop to repeatedly update within a unit time is a frequency, and the maximum permissible times for repeated updating of the said loop in a unit time is a maximum frequency, wherein said method comprises:

repeating the preceding processing step at an arbitrary frequency not exceeding said maximum frequency when repeatedly updating said request and repeatedly updating said loop.

8. The method for interchanging information according to claim 7, which is characterized in that the maximum frequency of the loop as a whole is confirmed by actual measurement of the frequency of the final stage processing step in the combination of said receiving side, said sending side, and said communication system.

9. The method for interchanging information according to claim 7, which is characterized in that charge is levied based on the amount of request information sent or the amount of information transmitted.

10. A method for interchanging information in which a receiving side, which receives information, sends to a sending side, which keeps said information, a request for transmission of said information through a communication system, said sending side, in response to said request, sends said receiving side said information through a communication system, and said receiving side receives said information which has been sent and displays said information in the form of an image with or without voice, wherein said method is characterized in that said request is composed of arbitrary position data and time data to specify arbitrary time and said information possesses said image with or without voice associated with said position data and said time data, with said image being so constructed as to be displayed in frame units, wherein said reQuest is repeatedly updated.

11. The method for interchanging information according to claim 10, which is characterized in that charge is levied based on the amount of request information sent or the amount of information transmitted.

12. A method for interchanging information in which a receiving side, which receives information, sends to a sending side, which keeps said information, a request for transmission of said information through a communication system, said sending side, in response to said request, sends said receiving side the information though a communication system, and said receiving side receives said information which has been sent and displays said information in the form of an image with or without voice, wherein said method is characterized in that said request is composed of arbitrary position data, viewing direction data indicating an arbitrary direction as said position, and time data to specific arbitrary time, and said information possesses said image with or without voice associated with said position data, said viewing direction data, and said time data, with said image being constructed as to be displayed in frame units, wherein said reciuest is repeatedly updated.

13. The method for interchanging information according to claim 12, which is characterized in that charge is levied based on the amount of request information sent or the amount of information transmitted.
