Referring back to FIG. 3, the user input unit 124 receives a user's command. In particular, according to an exemplary embodiment, the user input unit 124 may be a touch screen. However, this is only an example, and the exemplary embodiments may be applied to other input apparatuses, such as a mouse and a pointing device.
The control unit 122 controls the overall operation of the remote controller 120 according to a user command input to the user input unit 124. In particular, the control unit 122 may control to generate a playlist for playing contents of the multimedia apparatus 110.
Specifically, if a user inputs a specific command to generate a playlist, the control unit 122 controls to generate and display a content browsing screen as illustrated in FIG. 4.
In addition, if different kinds of contents are selected and collected from a plurality of content lists through the user input unit 124, the control unit 122 controls to generate and display a playlist including play information regarding the different kinds of collected contents.
Specifically, as illustrated in FIG. 5, if contents included in the plurality of content lists 410 are touched, dragged and dropped as the collection icon 440, the control unit 122 collects the contents. In this case, the collected contents may be a plurality of different kinds of contents. For example, if broadcast content is dragged and dropped as the collection icon 440, video content is dragged and dropped as the collection icon 440, and music content is dragged and dropped as the collection icon 440, the control unit 122 may collect the broadcast content, the video content, and the music content.
In addition, when the control unit 122 collects different kinds of contents, play information regarding the different kinds of contents may be input through the user input unit 124. In this case, a play start time may be included in the input play information. In particular, if the contents are photo contents, a play time may be included.
If different kinds of contents are collected, the control unit 122 controls to generate and display a playlist screen regarding the different kinds of collected contents as illustrated in FIG. 6. In this case, the displayed playlist screen includes a playlist 600 including play information, an automatic scheduling icon 610 and a play icon 620.
The playlist 600 includes play information regarding collected contents. In this case, the play information may include a title of content, a play start time, a play time, a date, a source, and so on as illustrated in FIG. 6. However, this is only an example, and the playlist may also include the type of content, a recommendation level, a thumbnail, and so on.
In general, the playlist schedules a program in the order of contents collected by a user. For example, if a user has collected contents in the order of “CSI: Miami”, “Inception”, and “The Dark Knight”, the playlist 600 may schedule the programs in the order of “CSI: Miami”, “Inception”, and “The Dark Knight” as illustrated in FIG. 6.
In addition, if one of “Title”, “Time”, “Date”, and “Source” displayed on the playlist 600 is touched in a row, the playlist 600 may schedule the contents in a decreasing or increasing order with respect to the touched item. For example, if “Time” is touched in a row, the playlist 600 may schedule the contents in the order of low play time, and if “Time” is touched in a row again, the playlist 600 may schedule the contents in the order of high play time.
The automatic scheduling icon 610 is an icon for scheduling a playlist automatically considering user information and broadcast information (a broadcast start time and a broadcast finish time).
Specifically, the method of scheduling a playlist considering broadcast information will be explain with reference to FIGS. 7A and 7B.
As illustrated in FIG. 7A, the playlist 600 includes three items of contents. In this case, the play start time of the video content, “The Dark Knight”, is 5 pm., and its play time is 150 minutes. The play start time of the broadcast content, “7 o'clock news”, is 7 pm., and its play time is 60 minutes. In addition, the play start time of the VOD content, “Inception”, is 8 pm, and its play time is 120 minutes.
If the three items of contents are played as described above, the video content, “The Dark Knight” may not be played for about 30 minutes since the start time of a broadcast content is fixed. Alternatively, the broadcast content, “7 o'clock news” may not be played for 30 minutes. That is, if broadcast content is included, specific content may not be played in its entirety due to a broadcast schedule of broadcast contents and play times of other contents.
In order to solve the above problem, the control unit 122 may generate a playlist by adjusting the play order of contents included in a playlist if the automatic scheduling icon 610 illustrated in FIG. 7A is selected.
Specifically, if the automatic scheduling icon 610 is selected, the control unit 122 selects contents provided in real time by selecting contents having information regarding the broadcast start time (or the play start time) from among contents collected in a playlist and extracts the broadcast start time and the play time (or the broadcast finish time) of the contents in order to schedule contents automatically considering contents provided in real time as a top priority. For example, as illustrated in FIG. 7A, the broadcast start time and the play time of “7 o'clock news” which is a content provided in real time from among the three items of contents are extracted.
In addition, the control unit 122 determines a play schedule of contents provided in real time and extracts play information of contents excluding the contents provided in real time. The control unit 122 adjusts the play order using the play information of the contents excluding the contents provided in real time so that the play time of the real-time contents is not overlapped with the play time of the remaining contents. For example, as illustrated in FIG. 7A, the play time of the video content, “The Dark Knight” which is supposed to start at 5 o'clock, is 150 minutes and thus, the play time of “The Dark Knight” is overlapped with the play time of “7 o'clock news”. Therefore, the control unit 122 changes the broadcast order of the video content, “The Dark Knight” which is supposed to start at 5 o'clock, with the broadcast order of the VOD content, “Inception” which is supposed to start at 8 o'clock. Therefore, “Inception” is finished before the broadcast content, “7 o'clock news” starts, and the broadcast content, “7 o'clock news” is played at 7 pm. Therefore, all of the three items of contents may be played without any interruption.
In addition, the control unit 122 may schedule a playlist automatically using user information. In this case, the user information may include information regarding a user's schedule, preference, viewing history, and so on.
Specifically, the control unit 122 extracts information regarding a user's schedule from information stored in the remote controller 120 and checks information regarding a case where it is difficult for a user to watch contents, such as a case where the user is away from home or a case where the user is in a place without access to a multimedia apparatus. The information regarding a user's schedule may be pre-stored in a multimedia apparatus, downloaded via the Internet, or received through an external apparatus, such as a tablet PC and a mobile phone. In addition, the control unit 122 schedules a playlist based on the information regarding a user's schedule so that a time when the user may not watch contents may be excluded from the playlist. For example, if a user goes out from 6 pm to 8 pm according to the information regarding the user's schedule, the control unit 122 schedules a playlist which does not play any content from 6 pm to 8 pm.
In addition, the control unit 122 may schedule a playlist automatically based on information regarding a user's preference, viewing history, and recommendation. Specifically, the control unit 122 may schedule a playlist automatically considering information regarding a user's preference input by the user in advance (for example, a preferred content type, a preferred content provider, a preferred content title, and so on). In this case, the control unit 122 may arrange to display content, which has been already watched by the user, later. In addition, the control unit 122 may arrange contents with the highest recommendation preferentially based on information regarding recommendation (by a third party).
As described above, if the automatic scheduling icon 610 is selected, a playlist is scheduled based on user information and broadcast schedule and thus, a user may watch all of the contents at a desired time in a desired order.
Meanwhile, in the above exemplary embodiment, if the automatic scheduling icon 610 is selected, a playlist is scheduled based on user information and broadcast schedule, but this is only an example. A playlist may be scheduled automatically based on user information and broadcast schedule if a plurality of contents are collected even if the automatic scheduling icon 610 is not selected.
The play icon 620 is an icon for inputting a command to play content according to a generated playlist. Specifically, if the play icon 620 is selected, the control unit 122 transmits the play information of a playlist to the multimedia apparatus 110 through the communication unit 121. Accordingly, the multimedia apparatus 110 plays contents according to the transmitted play information of a playlist.
If photo content is included in a playlist, the photo content may be played in a slide show. In this case, the control unit 122 may set a play time of each photo considering the number of photos included in the photo content and the play time of the photo content. For example, if a play time for a photo content is 30 minutes and there are 180 photos, the control unit 122 generates play information so that one picture may be played for 10 seconds.
As described above, according to an exemplary embodiment, different kinds of contents may be used and managed using a single list and thus, a user may use contents faster and more easily.
Hereinafter, a method for providing a playlist will be explained in detail with reference to FIG. 8. FIG. 8 is a view illustrating a method for providing a playlist according to an exemplary embodiment.
If a user's command to generate a playlist is input, the remote controller 120 displays a plurality of content lists on the first area of a display screen (S810). In this case, contents of a same kind are arranged together in the plurality of content lists.
Subsequently, the remote controller 120 determines whether content is selected according to a user's input (S820). If a content is selected (S820-Y), the remote controller collects the selected contents of the different kinds of contents (S830). When the remote controller 120 collects the contents of the different kinds of contents, play information regarding the different kinds of contents may be input through the user input unit 124. In this case, the play information may include a play start time. In particular, in the case of photo content, the play information may include a play time.
The remote controller generates and displays a playlist including the collected contents of the different kinds (S840). In this case, the generated playlist includes play information such as the title, type, play start time, play time, source and thumbnail of the contents.
After the playlist is generated and displayed, the remote controller determines whether a command to adjust a play order is input (S850). If a command to adjust a play order is input (S850-Y), the remote controller 120 adjusts the play order automatically considering broadcast information and user information (S860).
If a play command is input, the remote controller 120 transmits play information regarding the playlist to the multimedia apparatus 110 through a communication unit (S870).
As different kinds of contents are used and managed using a single list according to the above-described method for providing a playlist, a user may use contents faster and more easily.
Meanwhile, in the above exemplary embodiment, the remote controller 120 directly generates a playlist, but this is only an example. The exemplary embodiments may be applied when a playlist is downloaded from outside of the remote controller 120. For example, a playlist may be downloaded from another apparatus connected via a home network, or from an online store established on the web.
Although a few exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in the exemplary embodiments without departing from the principles and spirit of the inventive concept, the scope of which is defined in the claims and their equivalents.
