The recording request information includes the type of broadcasting of the broadcasting content, a broadcasting channel, a name of the broadcasting content, and an interrupted point in time of the broadcasting content.
The server 13 extracts an interrupted broadcasting content among the broadcasting content received in the server 13 based on the recording request information and records the extracted broadcasting content in the storage unit 14 from the interrupted point in time.
The interrupted broadcasting content is recorded according to a recording method set by the user through the mobile terminal 16. The recording method is one of a manual recording method, a specific broadcasting content recording method, and an automatic recording method. The manual recording method is a method of recording the interrupted broadcasting content whereby, if viewing of a broadcasting content is interrupted, the mobile terminal requests the server to record the broadcasting content if requested by the user. The specific broadcasting content recording method is a method whereby, if viewing of a specific broadcasting content specified by the user is interrupted, only the specific broadcasting content is recorded. The automatic recording method is a method whereby, if viewing of a broadcasting content is interrupted, the interrupted broadcasting content is automatically recorded.
The home terminal 18 may be one of a personal computer (PC) monitor and a television. The home terminal 18 is connected to the server 13 through a wire 21 or through a local area wireless communication network 22 such as Bluetooth® and wireless-fidelity (Wi-Fi). In the present exemplary embodiment, a first home terminal 18a is connected to the server 13 through the local area wireless communication network 22, and a second home terminal 18b is connected to the server 13 through the wire 21.

Upon request by the user, the mobile terminal 16 requests the server 13 to send broadcasting content in step S41. The server 13 receives the broadcasting content from the broadcasting station 12 in step S42, and sends the received broadcasting content to the mobile terminal 16 in step S43. The user selects broadcasting content to view among broadcasting contents received in the mobile terminal 16, and the mobile terminal 16 displays the selected broadcasting content in step S44. The mobile terminal 16 displays the selected broadcasting content in the display unit 17 in a streaming method.
Thereafter, if viewing of the selected broadcasting content is interrupted in step S45, the mobile terminal 16 determines if the user requests to record the interrupted broadcasting content in step S46. For example, the mobile terminal 16 displays a pop-up window for inquiring whether to record the interrupted broadcasting content in the display unit 17. A pop-up window for inputting “Yes” or “No” is displayed in the display unit 17, and the user selects “Yes” or “No” through key input, thereby determining whether to record the interrupted broadcasting content.
If the mobile terminal 16 receives a user request for recording, the mobile terminal 16 requests the server 13 to record the interrupted broadcasting content in step S47. The mobile terminal 16 sends recording instruction information to the server 13.
The server 13 extracts the interrupted broadcasting content from among broadcasting content received in the server 13 based on the recording request information in step S48. The server 13 records the extracted broadcasting content in the storage unit 14 from an interrupted point in time in step S49.
The user requests the mobile terminal 16 to reproduce the broadcasting content recorded in the server 13 at a desired location and time in step S50. The server 13 sends the recorded broadcasting content requested by the user to the mobile terminal 16 in step S51. The mobile terminal 16 displays the received recorded broadcasting content in step S52. Accordingly, the user can view the broadcasting content from the interrupted point in time at a desired location and time.
In the present exemplary embodiment, an example of requesting and viewing the broadcasting content recorded in the server 13 through the mobile terminal 16 is described, however the user can view the broadcasting content recorded in the server 13 through the home terminal 18 connected to the server 13.

Steps S61 to S65 in the execution process in step S35 of the specific broadcasting content recording method are identical to steps S41 to S45 of the manual recording method, and therefore a detailed description thereof is omitted.
If viewing of the selected broadcasting content is interrupted at step S65, the mobile terminal 16 determines if the interrupted broadcasting content is a specific broadcasting content in step S66. If the interrupted broadcasting content is a specific broadcasting content, the mobile terminal 16 requests the server 13 to record the interrupted broadcasting content in step S67.
Steps S68 to S72 of the specific broadcasting content recording method are identical to steps S48 to S52 of the manual recording method.
If the interrupted broadcasting content is not a specific broadcasting content at step S66, the mobile terminal 16 does not request the server 13 to record the interrupted broadcasting content, and a process of recording the interrupted broadcasting content is not performed.
FIGS. 5A and 5B is a message flow diagram illustrating an execution process of an automatic recording method selected in the method of FIG. 2.
Referring to FIGS. 1, 5A and 5B, the execution process in step S35 of the automatic recording method is described in detail as follows.
Steps S81 to S85 in the execution process in step S35 of the automatic recording method are identical to steps S41 to S45 of the manual recording method, and therefore a detailed description thereof is omitted.
If the selected broadcasting content 16 is interrupted at step S85, the mobile terminal 16 automatically requests the server 13 to record the interrupted broadcasting content in step S87.
Steps S88 to S92 of the automatic recording method are identical to steps S48 to S52 of the manual recording method.
In the present exemplary embodiment, an example in which the mobile terminal receives the broadcasting content sent from the broadcasting station via the server is described, however the mobile terminal can directly receive the broadcasting content from the broadcasting station.
A recording method that combines a specific broadcasting content recording method and a manual recording method can be used and is described as follows.
If viewing of a broadcasting content is interrupted, the mobile terminal determines if the interrupted broadcasting content is a specific broadcasting content. If the interrupted broadcasting content is a specific broadcasting content, the mobile terminal requests the server to record the interrupted broadcasting content. If the interrupted broadcasting content is not a specific broadcasting content, the mobile terminal performs a manual recording method by inquiring a user whether to record the interrupted broadcasting content.
As described above, according to the present invention, when viewing of broadcasting content is interrupted in a mobile terminal, the mobile terminal requests a server to record the interrupted broadcasting content, and the server records the broadcasting content from an interrupted point in time. Therefore, a user can request the terminal to reproduce the broadcasting content recorded in the server at a desired location and time and can view the broadcasting content from the interrupted point in time.
Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
