## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Korean Patent Application No. 2010-0085954 filed on Sep. 2, 2010, the entire disclosures of which are incorporated herein in its entirety by reference.
BACKGROUND
1. Field
Apparatuses and methods consistent with exemplary embodiments relate to continuously providing multimedia contents among multiple user devices, and more particularly, relate to providing a user with continuous utilization of a contents service without exposing location information of a mobile device.
2. Description of Related Art
As smart phones have become more widely used and a wireless internet technology has evolved, a service for providing video contents or the like on various screens of mobile devices, set top boxes and personal computers (PCs) in the same format has been developed, and utilization of the service has been on the rise.
A multiscreen contents service provides various kinds of user devices with information, music, and video contents through wired or wireless Internet links.
A user may enjoy the same contents through various reproduction devices and may continuously enjoy the same contents using multiple reproduction devices.
Korean Patent No. 10-0640490 entitled “Multi-user support content mobility method and apparatus” (hereinafter “Patent Document 1,” the disclosure of which is incorporated herein by reference) relates to a technology capable of supplying contents, from a fixed display device, continuously through a portable display device.
Although Patent Document 1 provides mobility between contents reproduction devices by interconnecting a fixed display device and a mobile display device, a redirection between reproduction devices is not made automatically.

Hereinafter, a process for providing a continuous contents reproduction service in a continuous contents reproduction service providing server in accordance with an exemplary embodiment will be explained with reference to FIG. 4.
FIG. 4 is a flowchart for explaining a process in a continuous contents reproduction service providing server 200 in accordance with an exemplary embodiment.
As depicted in FIG. 4, location measurement information of a fixed user device 100-1, such as an IP address of the fixed user device 100-1 transmitted at the time of starting a process, etc., may be received, and location information of the fixed user device 100-1 may be obtained based on the received location measurement information such as the IP address, etc. (operation S400). Thereafter, the obtained location information of the fixed user device 100-1 may be registered (operation S402).
Thereafter, the continuous contents reproduction service providing server 200 may check whether a reproducing of contents is interrupted in a user device 100, and if the reproducing of contents is interrupted (operation S404), the continuous contents reproduction service providing server 200 may determine whether the user device in which the reproducing of contents is interrupted is a fixed user device 100-1 or a mobile user device 100-2 (operation S412).
If the reproducing of contents is interrupted in the fixed user device 100-1, information of the mobile user device 100-2 may be obtained by using information of user devices registered by the user (operation S414), and a continuous reproduction information message may be transmitted to the mobile user device 100-2 (operation S416). In such cases, the transmitted continuous reproduction information message may be transmitted from the fixed user device 100-1 in which the reproducing of contents is interrupted, or may be generated from the continuous contents reproduction service providing server 200 right after the reproducing of contents is interrupted. Further, after the continuous reproduction information message is transmitted to the mobile user device 100-2, the corresponding continuous reproduction information message may be deleted from the message DB 250 (operation S418).
If the reproducing of contents is interrupted in the mobile user device 100-2, a continuous reproduction information message may be transmitted to a specific fixed user device 100-1 determined by the mobile user device 100-2 by using information such as a distance between the devices (operation S420). In such cases, the transmitted continuous reproduction information message may be transmitted from the mobile user device 100-2 in which the reproducing of contents is interrupted, or may be generated from the continuous contents reproduction service providing server 200 right after the reproducing of contents is interrupted. Further, after the continuous reproduction information message is transmitted to the fixed user device 100-1, the corresponding continuous reproduction information message may be deleted from message DB 250 (operation S422).
If the reproducing of contents is not interrupted, the message DB 250 may determine whether the continuous reproduction information message is received (operation S406), and if the continuous reproduction information message is received, the message DB 250 may determine whether the received message is valid (operation S408).
If the continuous reproduction information message is valid, the continuous reproduction information message may be transmitted to a user device 100 serving as a destination of the continuous reproduction information message (operation S416). After the continuous reproduction information message is transmitted to the user device 100, the corresponding continuous reproduction information message may be deleted from message DB 250 (operation S418).
In such cases, if the continuous reproduction information message is received from a mobile user device 100-2, the corresponding continuous reproduction information message may be transmitted to a fixed user device 100-1, and if the continuous reproduction information message is received from the fixed user device 100-1, the continuous reproduction information message may be transmitted to the mobile user device 100-2.
Hereinafter, a process in a mobile user device 100-2 will be explained as an example of a method for providing a continuous contents reproduction service in accordance with an exemplary embodiment with reference to FIG. 5.
FIG. 5 is a flowchart for explaining a process in a mobile user device 100-2 for providing a continuous contents reproduction service in accordance with an exemplary embodiment.
As depicted in FIG. 5, it may be determined whether a reproducing of contents is interrupted in the mobile user device 100-2 (operation S500).
If the reproducing of contents is interrupted and a service closing event is generated in the mobile user device 100-2, a timer may start for a predetermined time (operation S502), and location information of a fixed user device 100-2 may be received from a continuous contents reproduction service providing server 200 (operation S504).
Thereafter, location information of the mobile user device 100-2 may be measured (operation S506), and it may be determined whether there is a fixed user device 100-1 available within a certain distance from the mobile user device 100-2 (operation S508). If there is a fixed user device 100-1 satisfying this condition, a continuous reproduction information message may be transmitted to the corresponding fixed user device 100-1 (operation S510). If there is no fixed user device 100-1 satisfying this condition, operation S506 and S508 may be repeated until the timer stops (operation S512).
If the service closing event is not generated, it may be checked whether a continuous reproduction information message is received from a fixed user device 100-1 (operation S514).
If there is a received message, the timer may start for a predetermined time (operation S516), and location information of the fixed user device 100-1 may be received from the continuous contents reproduction service providing server 200, and location information of the mobile user device 100-2 may be measured (operation S518).
If the fixed user device 100-1 and the mobile user device 100-2 are distanced by a certain distance or greater from each other (operation S520), the mobile user device 100-2 may display, on its screen, a suggestion of using the continuous contents reproduction service to the user (operation S522). If the user accepts the suggestion (operation S524), the mobile user device 100-2 may request to continuously provide the contents to the continuous contents reproduction service providing server 200 (operation S526). In such cases, the mobile user device 100-2 may be configured to suggest using the continuous contents reproduction service to the user without comparing a distance from the fixed user device 100-1.
As described above, even if location information of a mobile user device of a user is not transmitted to a continuous contents reproduction service providing server, it may be possible to suggest to the user whether or not to continuously use contents by measuring a distance between the mobile user device and a fixed user device, and thus, it may be possible to protect location information of the user.
