Abstract

An information processing apparatus includes a data receiver that receives data from one or more apparatuses, processing circuitry that determines a transfer priority of the data received by the data receiver based on data type, and a data transmitter that transfers the data to apparatuses other than the apparatus that transferred the data in accordance with the transfer priority. The processing circuitry determines if there is any data that has not been transferred during a predetermined data transfer period, and, based on determination indicating that there is data that has not been transferred, modifies the transfer priority of the data that has not been transferred to have a transfer priority higher than that of data to be transferred next, to cause the data transmitter to transfer the data having the modified transfer priority preferentially to apparatuses other than the apparatus that transferred the data.

Claims

1. An information processing apparatus, comprising:

a data receiver that receives first data from an apparatus;

a user interface configured to

display a screen image; and

receive second data, the second data being stroke data that is input upon the screen image by a user of the user interface;

a data transmitter that

transmits the screen image to one or more apparatuses, including the apparatus from which the data receiver received the first data; and

transmits the first data and the second data to the one or more apparatuses, in accordance with a transfer priority of the first data and the second data; and

processing circuitry configured to

determine the transfer priority according to a data type of the first data and the second data and a source of the first data and the second data, wherein the processing circuitry grants the second data received via the user interface a higher priority than the first data received via the data receiver;

determine, after expiration of a predetermined data transfer period, whether data to be transferred during the predetermined data transfer period was not transferred during the predetermined data transfer period;

modify, when the data was not transferred during the predetermined data transfer period, the transfer priority of the data to be a higher priority than that of other data to be transferred next; and

control the data transmitter to transfer the data having the modified transfer priority preferentially to the one or more apparatuses.

2. The information processing apparatus according to claim 1, further comprising:

an information storage configured to store data priority information that associates the data type with the transfer priority of the data, wherein

the processing circuitry determines the transfer priority with reference to the data priority information.

3. The information processing apparatus according to claim 1, further comprising:

a history storage configured to store information, relating to data transferred by the data transmitter, as history information, wherein

the processing circuitry determines, whether the data to be transferred during the predetermined data transfer period was not transferred during the predetermined data transfer period, according to the history information.

4. The information processing apparatus according to claim 1, wherein the predetermined data transfer period is specified in accordance with the data type.

5. The information processing apparatus according to claim 1, further comprising:

a data storage configured to store data that the data receiver receives, wherein

the processing circuitry is further configured to retrieve the data stored in the data storage, determine the transfer priority of the data, store the data while rearranging the data in accordance with the determined transfer priority, retrieve data to be arranged in accordance with the transfer priority from the data storage, and pass the retrieved data to the data transmitter.

6. The information processing apparatus according to claim 1, further comprising:

a data storage configured to store data received by the data receiver in accordance with the transfer priority determined by the processing circuitry;

wherein

the data transmitter retrieves and transfers data to be arranged in accordance with the transfer priority from the data storage.

7. The information processing apparatus according to claim 1, wherein the processing circuitry determines the transfer priority in response to data reception by the data receiver or data transmission by the data transmitter and determines whether or not the data that has not been transferred is within the predetermined data transfer period.

8. The information processing apparatus according to claim 1, wherein the first data is image data, sound data, video data, pointing data or stroke data.

9. An information processing system, comprising:

a plurality of apparatuses; and

an information processing apparatus configured to control communication among the plurality of apparatuses, the information processing apparatus comprising;

a data receiver that receives first data from an apparatus of the plurality of apparatuses;

a user interface configured to

display a screen image; and

receive second data, the second data being stroke data that is input upon the screen image by a user of the user interface;

a data transmitter that

transmits the screen image to one or more apparatuses, including the apparatus from which the data receiver received the first data; and

transmits the first data and the second data to the one or more apparatuses, in accordance with a transfer priority of the first data and the second data; and

processing circuitry configured to

determine the transfer priority according to a data type of the first data and the second data and a source of the first data and the second data, wherein the processing circuitry grants the second data received via the user interface a higher priority than the first data received via the data receiver;

determine, after expiration of a predetermined data transfer period, whether data to be transferred during the predetermined data transfer period was not transferred during the predetermined data transfer period;

modify, when the data was not transferred during the predetermined data transfer period, the transfer priority of the data to be a higher priority than that of other data to be transferred next; and

control the data transmitter to transfer the data having the modified transfer priority preferentially to the one or more apparatuses.

10. A method of controlling communication in an information processing system, the method comprising:

receiving, by an information processing apparatus, first data from an apparatus in the information processing system;

displaying, by a user interface of the information processing apparatus, a screen image;

receiving, by the user interface, second data that is stroke data input upon the screen image by a user of the user interface;

determining, by processing circuitry of the information processing apparatus, a transfer priority according to a data type of the first data and the second data and a source of the first data and the second data, wherein the processing circuitry grants the second data received via the user interface a higher priority than the first data received via the data receiver;

transferring the screen image to one or more apparatuses, including the apparatus from which the first data is received;

transferring the first data, and the second data to the one or more apparatuses in accordance with the transfer priority of the first data and the second data;

determining, after expiration of a predetermined data transfer period, whether data to be transferred during the predetermined data transfer period was not transferred during the predetermined data transfer period;

modifying, the processing circuitry when the data was not transferred during the predetermined data transfer period, the transfer priority of the data to be a higher priority than that of other data to be transferred to next; and

transferring the data having the modified transfer priority preferentially to the one or more apparatuses.
