Abstract

In content distribution, even if a reservation for a distribution channel and a distribution time slot is not performed before a predetermined time is reached, in response to a real-time distribution reservation request from a user PC, a predetermined time period including a current time at which the request is received is reserved in a channel which is unoccupied at the current time. A reservation setting information file concerning the reservation is also transmitted to the user PC, and reservation data is sent to a server-use reservation management center. Thus, the content received from the user PC is immediately distributed to clients via a streaming server according to the reservation setting information file.

Claims

1. A content distribution system comprising:

a user terminal;

a content distribution server configured to distribute video content received from said user terminal via a first network to a client via a second network;

a content reservation management apparatus configured to transmit a menu to the user terminal via the second network, the menu configured to display service times and unoccupied available channels to distribute content from the content distribution server and a service fee, availability and cost corresponding to each of the available service times and unoccupied available channels; and

the content reservation management apparatus configured to receive a reservation via said second network for a distribution channel and a time slot in which the distribution channel is to be used from said user terminal,

wherein said content reservation management apparatus receives a real time distribution reservation request via said second network from said user terminal in order to immediately distribute the content,

in response to the real-time distribution reservation request, said content reservation management apparatus reserves a current time at which the request is received, in a requested distribution channel which is unoccupied at the current time, and sends reservation setting information concerning the reservation to said user terminal and to said content distribution server; and

said content distribution server immediately distributes at the current time the content received from said user terminal via said first network according to the reservation setting information.

2. A content distribution system according to claim 1, wherein said content reservation management apparatus makes the reservation in minimum units of time, and performs billing processing in the minimum units of time even for a time period, including the current time, which is smaller than the minimum units of time.

9. A content distribution system according to claim 1, wherein said content reservation management apparatus includes a reservation data base in which at least the time slot and the distribution channel corresponded with each other, and

the content reservation management apparatus is configured to refer to the reservation data base to determine an unoccupied distribution channel at the current time.

13. The content distribution system of claim 1, wherein the first network is a dedicated network and the second network is an Internet connection.

3. A content reservation management apparatus for receiving a reservation for a distribution channel and a time slot in which the distribution channel is to be used from a user terminal when content received from the user terminal is distributed from a content distribution server to a client via a network, and for managing the received reservation, said content reservation management apparatus comprising:

an interface configured to transmit a menu to the user terminal via the first network, the menu configured to display service times and unoccupied available channels to distribute content from the content distribution server and a service fee, availability and cost corresponding to each of the available service times and unoccupied available channels;

real-time distribution reservation receiving means for receiving a real-time distribution reservation request from the user terminal via a first network in order to immediately distribute the content; and

control means, for reserving, in response to the real-time distribution reservation request from said user terminal a current time at which the request is received, in a requested distribution channel which is unoccupied at the current time, and sending reservation setting information concerning the reservation to the user terminal and to the content distribution server, thereby achieving real-time distribution at the current time for immediately distributing the content received from the user terminal via a second network to the client via said first network in real time via the content distribution server based on the reservation setting information.

4. A content reservation management apparatus according to claim 3, wherein said control means makes the reservation in minimum units of time, and performs billing processing in the minimum units of time even for a time period including the current time, which is smaller than the minimum units of time.

10. A content reservation management apparatus according to claim 3, wherein said control means includes a reservation data base in which at least the time slot and the distribution channel corresponded with each other, and

the control means includes means for referring to the reservation data base to determine an unoccupied distribution channel at the current time.

14. The content reservation management apparatus of claim 3, wherein the first network is an Internet connection and the second network is a dedicated network.

5. A content reservation management method for receiving a reservation for a distribution channel and a time slot in which the distribution channel is to be used from a user terminal when video content received from the user terminal is distributed from a content distribution server to a client via a network, and for managing the received reservation, said content reservation management method comprising:

transmitting a menu to the user terminal, the menu configured to display service times and unoccupied available channels to distribute content from the content distribution server and a service fee, availability and cost corresponding to each of the available service times and unoccupied available channels;
