Abstract

The present invention relates to a method and apparatus of providing a shared Video on Demand (VoD) broadcasting service using a mobile communication network. The method and apparatus may concurrently provide, to a plurality of terminals requesting a first content, requested content from among broadcasting requested contents selected from a broadcasting content list, thereby effectively using radio resources.

Claims

1. A server of providing shared Video on Demand (VoD) broadcasting services, the server comprising:

a content designation unit to designate a first priority requested content based on information received from a plurality of terminals;

an available resource determining unit to determine an available resource with respect to respective cells including the terminal requesting the first priority requested content; and

a stream transmission unit to assign, to the respective cells, resources used for transmitting the first priority requested content, and to transmit a stream with respect to the first priority requested content, when all of the respective cells have the available resource for providing the first priority requested content.

2. The server of claim 1, wherein, when a cell without the available resource for providing the first priority requested content exists among the respective cells, the stream transmission unit enters and remains in a wait state until the cell without the available resource obtains the available resource.

3. The server of claim 1, wherein the content designation unit comprises:

a broadcasting list providing unit to provide, to the plurality of terminals, a content list to be broadcasted; and

a request list collecting unit to collect a requested content list from the plurality of terminals, wherein

a requested content having a greatest number of requests from the collected requested content list is designated as the first priority requested content.

4. The server of claim 1, wherein the available resource determining unit comprises:

a cell identification unit to identify the respective cells where the terminal requesting the first priority requested content exists; and

a content providing-determination unit to determine whether the first priority requested content is provided based on information about a use of resource with respect to the respective cells.

5. The server of claim 4, wherein the information received from a plurality of terminals includes cell information where each of the plurality of terminals exists, and the cell identification unit identifies the respective cells based on the cell information.

6. The server of claim 4, wherein the cell identification unit comprises a position retrieval unit to retrieve position information with respect to the plurality of terminals existing in a separate position information server based on the information received from the plurality of terminals, and identifies a cell with respect to each of the plurality of terminals based on the position information retrieved in the position information server.

7. The server of claim 1, further comprising:

an internal memory including at least one of a content ranking list, an amount of used resources for each cell, and a reception content list for each terminal.

8. The server of claim 7, wherein, when the stream transmission unit transmits the stream for the first priority requested content, the internal memory initializes a ranking of the first priority requested content stored in the content ranking list.

9. A terminal of receiving shared Video on Demand (VoD) broadcasting services, the terminal comprising:

a broadcasting list receiving unit to receive a broadcasting content list from a broadcasting service providing server;

a request list sending unit to send a requested content list selected from the broadcasting content list; and

a content output unit to receive and output contents to be broadcasted.

10. The terminal of claim 9, wherein the request list sending unit sends the requested content list and terminal identification information.

11. A base station of providing shared Video on Demand (VoD) broadcasting services, the base station comprising:

a request list transmitting unit to transmit, to a broadcasting service providing server, a broadcasting requested content list received from a plurality of terminals;

a broadcasting list transmitting unit to receive a broadcasting content list from the broadcasting service providing server, and to transmit the received broadcasting content list to the plurality of terminals; and

a content transmission unit to transmit, to the plurality of terminals, contents received from broadcasting service providing server.

12. The base station of claim 11, wherein the request list transmitting unit transmits, to the broadcasting service providing server, the broadcasting requested content list and information about a cell including the plurality of terminals.

13. The base station of claim 11, wherein the content transmission unit comprises:

a resource assignment unit to allocate a bandwidth for transmitting contents; and

a stream transmission unit to transmit a content stream using the allocated bandwidth, wherein

the resource assignment unit enters and remains in a wait state until an available bandwidth for transmitting the contents is obtained, when the available bandwidth is unavailable.

14. A method of providing shared Video on Demand (VoD) broadcasting services, the method comprising:

providing, to a plurality of terminals, a content list to be broadcasted, and collecting, from the plurality of terminals, terminal information including a requested content list;

designating a first priority requested content by ranking the collected requested content list;

determining an available resource with respect to respective cells including the terminal requesting the first priority requested content; and

assigning, to the respective cells, a resource for transmitting the first priority requested content when all of the respective cells have the available resource for providing the first priority requested content, and transmitting a stream with respect to the first priority requested content.

15. The method of claim 14, further comprising:

remaining in a wait state until a cell without the available resource for providing the first priority requested content obtains the available resource, when the cell without the available resource exists.

16. The method of claim 14, wherein the designating designates, as the first priority requested content, a requested content having a greatest number of requests from the collected requested content list.

17. The method of claim 14, wherein the determining comprises:

identifying the respective cells where the terminal requesting the first priority requested content exists; and

determining whether the first priority requested content is provided based on information about a use of resource with respect to the respective cells.

18. The method of claim 17, wherein the terminal information includes cell information where each of the plurality of terminals exists, and the identifying identifies the respective cells based on the cell information.

19. The method of claim 17, wherein the identifying comprises:

retrieving position information with respect to the plurality of terminals existing in a separate position information server based on the information received from the plurality of terminals; and

identifying a cell with respect to each of the plurality of terminals based on the position information retrieved in the position information server.

20. The method of claim 14, wherein the transmitting of the stream comprises initializing a ranking of the first priority requested content stored in the content ranking list.
