Information distribution apparatus that resumes distribution after interruption
First Claim
1. An information distribution apparatus for transmitting distribution information as real-time information, comprising:
- distribution means for transmitting the distribution information in real time to a receiver terminal;
distribution information storage means for separately storing the distribution information to be transmitted by the distribution information;
interruption information storage means which, in the event that transmission of distribution information from the distribution means to a certain receiving terminal is interrupted, stores specific information for specifying a position on the distribution information where interruption has arisen; and
re-distribution means which, in response to a request from the receiving terminal, loads from the distribution information storage means partial information which constitutes a portion of the distribution information stored in the distribution information storage means and is subsequent to a position specified by specific information that is stored in the interruption information storage means, and which transmits the partial information.

Abstract
The invention relates to an information distribution apparatus capable of distributing multimedia information without fail even if interruption has arisen in real-time distribution of multimedia information. In the information distribution apparatus, distribution information serving as real-time information is received by the receiving end, while being stored in a storage section provided in the sending end. Even if distribution is interrupted in the course of distribution, a time stamp corresponding to the time at which interruption has arisen is stored. When a re-transmission request is issued by the receiving end, distribution information is loaded from a memory location corresponding to the time stamp, and the thus-loaded information is transmitted to the receiving end. In this case, the speed at which information is loaded from the storage section is increased so as to catch up with real-time distribution.

8. An information distribution apparatus for transmitting distribution information as real-time information, comprising:
-
input means for entering the distribution information; distribution means for transmitting in real time to a receiving end the distribution information that has been entered by way of the input means to a receiver terminal; distribution information storage means for separately storing the distribution information that has been entered by way of the input means; interruption information storage means which, in the event that transmission of distribution information from the distribution means to a certain receiving terminal is interrupted, stores specific information for specifying a position on the distribution information where interruption has arisen; and re-distribution means which, in response to a request from the receiving terminal, loads from the distribution information means partial information which constitutes a portion of the distribution information stored in the distribution information storage means and is subsequent to a position specified by specific information that is stored in the interruption information storage means, and which transmits the partial information. - View Dependent Claims (9, 10)

11. An information distribution apparatus for transmitting distribution information as real-time information, comprising:
-
input means for entering the distribution information; distribution means for transmitting the distribution information to a receiving end; distribution information storage means for separately storing the distribution information that has been entered by way of the input means; interruption information storage means which, in the event that transmission of distribution information from the distribution means to a certain receiving terminal is interrupted, stores specific information for specifying a position on the distribution information where interruption has arisen; and a controller which stores into the distribution information storage means the distribution information that has been input by way of the input means and controls the distribution means so as to transmit the distribution information in real time when transmission of the distribution information to the receiving terminal is not interrupted; and
which stores the specific information into the interruption information storage means when transmission of distribution information to a certain receiving terminal is interrupted, which loads, when a request is issued by the receiving terminal, partial information from the distribution information storage means, the partial information constituting a portion of the distribution information stored in the distribution information storage means and being subsequent to a position specified by specific information stored in the interruption information storage means, and which controls the distribution device so as to distribute the partial information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
