Information processing apparatus, conference system, and storage medium

1. An information processing apparatus for a conference system where a plurality of terminals are connected via a network to the information processing apparatus and exchange data via the information processing apparatus to conduct a conference, the information processing apparatus comprising:

a detection unit that detects disconnection of a terminal of the terminals from the information processing apparatus and recovery of the terminal from the disconnection;

a recording unit;

a data transmission unit; and

a status management unit that

causes the recording unit to start recording the data in a storage when the disconnection is detected by the detection unit, and

causes the data transmission unit to transmit the data read from the storage to the terminal in response to a data transmission request from the terminal,

wherein the information processing apparatus is configured to allow the terminal to select items to be detected by the detection unit, contents of the data to be recorded by the recording unit, and contents of the data to be transmitted by the data transmission unit.

2. The information processing apparatus as claimed in claim 1 , wherein the status management unit

causes the recording unit to record the data in the storage during a period from when the disconnection is detected to when the recovery is detected by the detection unit, and

causes the data transmission unit to transmit the data recorded during the period to the terminal.

3. The information processing apparatus as claimed in claim 1 , wherein the status management unit

causes the recording unit to record the data in the storage during a period from when the disconnection is detected by the detection unit to when the conference ends, and

causes the data transmission unit to transmit the data recorded during the period to the terminal.

4. The information processing apparatus as claimed in claim 1 , wherein

the detection unit detects at least one of a network delay and a frame rate; and

the status management unit

causes the recording unit to record the data in the storage during a period when at least the network delay is greater than or equal to a threshold or the frame rate is less than or equal to a threshold, and

causes the data transmission unit to transmit the data recorded during the period to the terminal.

5. The information processing apparatus as claimed in claim 1 , wherein the data transmission unit streams the data read from the storage to allow the terminal to play the data while receiving the data.

6. The information processing apparatus as claimed in claim 1 , wherein the status management unit causes the data transmission unit to transmit the data read from the storage to a terminal that is different from the terminal whose disconnection is detected by the detection unit.

7. A conference system, comprising:

an information processing apparatus; and

a plurality of terminals that are connected via a network to the information processing apparatus and exchange data via the information processing apparatus to conduct a conference,

wherein the information processing apparatus includes

a detection unit that detects disconnection of a terminal of the terminals from the information processing apparatus and recovery of the terminal from the disconnection,

a recording unit,

a data transmission unit, and

a status management unit that

causes the recording unit to start recording the data in a storage when the disconnection is detected by the detection unit, and

causes the data transmission unit to transmit the data read from the storage to the terminal in response to a data transmission request from the terminal; and

wherein each of the terminals includes

a transmission requesting unit that requests the information processing apparatus to transmit the data recorded in the storage after the recovery from the disconnection, and

a playback unit that plays the data received from the information processing apparatus,

wherein the information processing apparatus is configured to allow the terminal to select items to be detected by the detection unit, contents of the data to be recorded by the recording unit, and contents of the data to be transmitted by the data transmission unit.

8. A non-transitory computer-readable storage medium storing program code for causing a computer to function as an information processing apparatus for a conference system where a plurality of terminals are connected via a network to the information processing apparatus and exchange data via the information processing apparatus to conduct a conference, the information processing apparatus comprising:

a detection unit that detects disconnection of a terminal of the terminals from the information processing apparatus and recovery of the terminal from the disconnection;

a recording unit;

a data transmission unit; and

a status management unit that

causes the recording unit to start recording the data in a storage when the disconnection is detected by the detection unit, and

causes the data transmission unit to transmit the data read from the storage to the terminal in response to a data transmission request from the terminal,

wherein the information processing apparatus is configured to allow the terminal to select items to be detected by the detection unit, contents of the data to be recorded by the recording unit, and contents of the data to be transmitted by the data transmission unit.
