BROADCAST-LINKED SERVICE BASED ON CLOUD STREAMING, BROADCAST-LINKED SERVICE CLIENT APPARATUS, TRIGGER CONTENT PROVIDING SERVER
Disclosed are a system for a cloud streaming-based broadcast-associated service, a client apparatus for the broadcast-associated service, a trigger content provision server and a method utilizing same. The client apparatus for a broadcast-associated service receives trigger content and associated information for which a different screen for each user need not be provided from the trigger content provision server without going through a cloud streaming server, thereby allowing a large number of broadcast service clients to be serviced by a small number of trigger content provision servers, and the service via the cloud streaming server is received only when a user input for the trigger content exists, thereby allowing an associated service to be interactively provided with just the optimum resources.
1 . A broadcast-linked service client apparatus comprising:
a communication unit which receives a service condition defined by a user-specific broadcast-linked defining server and receives trigger content corresponding to the service condition from a trigger content providing server; and
a control unit which executes a trigger application to display the trigger content linked to broadcast content, receives a user-specific application execution result screen from a cloud streaming server, based on a user input corresponding to the trigger content, and offers the received screen to a user.
2 . The broadcast-linked service client apparatus of claim 1 , wherein the trigger content is shared by greater numbers of users than users who share the application execution result screen.
3 . The broadcast-linked service client apparatus of claim 2 , wherein the service condition includes a broadcast type condition and a timing condition which are set depending on a user group.
4 . The broadcast-linked service client apparatus of claim 2 , wherein the trigger content contains one or more of a cloud streaming application identifier and other trigger content identifier for providing the broadcast-linked service when the trigger content is selected.
5 . The broadcast-linked service client apparatus of claim 2 , wherein the trigger content is transmitted at a transmission timing determined differently for each user in view of a load of the trigger content providing server.
6 . The broadcast-linked service client apparatus of claim 2 , wherein if there are two or more keys connected with the trigger content, the trigger content providing server provides a cloud streaming application identifier or other trigger content identifier connected with each key together with the trigger content.
7 . A trigger content providing server comprising:
a request receiving unit which receives, from a trigger application executed in a client, a request for trigger content required for a broadcast-linked service;
a transmission timing determining unit which determines a transmission timing of the trigger content by considering one or more of an exposure time of the trigger content and a server load; and
a trigger content transmitting unit which provides the trigger content to the client at the transmission timing such that the broadcast-linked service is performed through a cloud streaming service when there is a user input corresponding to the trigger content.
8 . The trigger content providing server of claim 7 , wherein the transmission timing determining unit determines differently the transmission timing for respective clients in view of the server load.
9 . The trigger content providing server of claim 8 , wherein the transmission timing determining unit determines the transmission timing such that the trigger content is transmitted before the exposure time.
10 . The trigger content providing server of claim 9 , wherein the trigger content is shared by greater numbers of users than users corresponding to the cloud streaming service.
11 . A broadcast-linked service system based on cloud streaming, the system comprising:
a user-specific broadcast-linked service defining server which provides a service condition for a broadcast-linked service;
a trigger content providing server which provides trigger content corresponding to the service condition;
a client apparatus which executes a trigger application to display the trigger content linked to broadcast content, receives a user-specific application execution result screen created based on a user input corresponding to the trigger content, and offers the received screen to a user; and
a cloud streaming server which creates the execution result screen by executing a user-specific application based on the user input.
