Abstract

In a transmitting terminal, a first displaying section displays, synchronously with a receiving terminal, a portion of content that has been transmitted to the receiving terminal. A second displaying section displays a portion of the content that has yet to be transmitted to the receiving terminal. A saving flag setting section sets a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save the content after the receiving terminal receives and displays the content. An adder adds the saving flag to the content; and a transmitter transmits the content to the receiving terminal with the saving flag.

Claims

1. An information processing system including:

a transmitting terminal; and

a receiving terminal for receiving content from the transmitting terminal,

wherein the transmitting terminal includes;

first displaying means for displaying, synchronously with the receiving terminal, a portion of the content that has been transmitted to the receiving terminal;

second displaying means for displaying a portion of the content that has yet to be transmitted to the receiving terminal;

saving flag setting means for setting a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save the content after the receiving terminal receives and displays the content, the saving flag being set while the first displaying means is displaying the portion of the content that has been transmitted to the receiving terminal and while the second displaying means is displaying the portion of the content that has yet to be transmitted to the receiving terminal;

adding means for adding the saving flag to the content; and

transmitting means for transmitting the content to the receiving terminal with the saving flag, and

wherein the receiving terminal includes;

receiving means for receiving the content from the transmitting terminal;

third displaying means for displaying the received content synchronously with the transmitting terminal;

saving setting means for setting whether to save the received content, the setting being made while the third displaying means is displaying the received content;

determining means for determining whether the saving flag permits or prohibits saving the received content; and

saving means for saving the received content when the setting indicates to save the received content and the saving flag indicates that the saving of the received content is permitted.

2. A transmitting terminal for transmitting content to a receiving terminal, the transmitting terminal comprising:

first displaying means for displaying, synchronously with the receiving terminal, a portion of the content that has been transmitted to the receiving terminal;

second displaying means for displaying a portion of the content that has yet to be transmitted to the receiving terminal;

saving flag setting means for setting a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save the content after the receiving terminal receives and displays the content, the saving flag being set while the first displaying means is displaying the portion of the content that has been transmitted to the receiving terminal and while the second displaying means is displaying the portion of the content that has yet to be transmitted to the receiving terminal;

adding means for adding the saving flag to the content; and

transmitting means for transmitting the content to the receiving terminal with the saving flag.

3. The transmitting terminal as claimed in claim 2, wherein the content includes sound data and image data.

4. The transmitting terminal as claimed in claim 2, further comprising:

time information obtaining means for obtaining time information; and

reproduction time information setting means for setting a reproduction time for the content;

wherein the adding means adds information about the reproduction time to the content in addition to the saving flag, and

the first displaying means displays the portion of the content that has been transmitted to said receiving terminal at the reproduction time, synchronously with the receiving terminal.

5. A method of transmitting content the method comprising:

displaying, synchronously with a receiving terminal, a portion of the content that has been transmitted to the receiving terminal;

displaying a portion of the content that has yet to be transmitted to the receiving terminal;

setting a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save content after the receiving terminal receives and displays the content, the saving flag being set while displaying both the portion of the content that has been transmitted to the receiving terminal and the portion of the content that has yet to be transmitted to the receiving terminal;

adding the saving flag to the content; and

transmitting the content to the receiving terminal with the saving flag.

6. A medium containing processor readable instructions for causing a processor to execute a method of transmitting content, the method comprising:

displaying, synchronously with a receiving terminal, a portion of the content that has been transmitted to the receiving terminal;

displaying a portion of the content that has yet to be transmitted to the receiving terminal;

setting step of setting a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save the content after the receiving terminal receives and displays the content, the saving flag being set while displaying both the portion of the content that has been transmitted to the receiving terminal and the portion of the content that has yet to be transmitted to the receiving terminal;

adding the saving flag to the content; and

transmitting the content to the receiving terminal with the saving flag.

7. A receiving terminal for receiving content transmitted from a transmitting terminal, the receiving terminal comprising:

receiving means for receiving the content transmitted from the transmitting terminal, the received content including a saving flag specifying whether to permit or prohibit saving of the received content after the received content is displayed;

displaying means for displaying the received content synchronously with the transmitting terminal;

saving setting means for making a setting indicating whether to save the received content, the setting being made while the displaying means is displaying the received content;

determining means for determining whether the saving flag permits or prohibits saving the received content; and

saving means for saving the received content when the setting indicates to save the received content and the saving flag specifies that saving the received content is permitted.

10. The receiving terminal as claimed in claim 7,

wherein saving means erases the received content if the setting indicates not to save the received content or the saving flap specifies that the saving of the received content is prohibited.

11. A method of receiving content transmitted from a transmitting terminal, the method comprising:
