         [0020]    The above system and/or units, in some embodiments, include by one or more micro-processors or Integrated Circuits (ICs) of one or more computer systems. The one or more processors or Application-Specific Integrated Circuits (ASICs) are hardwired and/or programmed to perform the described example operations. Further, the described example operations are not necessarily required to be performed in the order shown and/or described. Operations may be added, replaced, changed order, and/or eliminated as appropriate, in accordance with the spirit and scope of embodiments of the disclosure. Embodiments that combine different features and/or different embodiments are within the scope of the disclosure and will be apparent to those of ordinary skill in the art after reviewing this disclosure. 
         [0021]    According to an embodiment of the inventive concept, a display area of the first display unit  20  may have a size corresponding to the whole display screen. However, the scope and spirit of the inventive concept may not be limited thereto. For example, the first display unit  20  may be restrictively displayed on a portion of the display screen. 
         [0022]    The second display unit  30  may include a progress unit  31  for representing a progress state of the playback content being currently played and a display unit  41  for displaying a screen about the playback content. A display area of the second display unit  30  may be set to have a size which is smaller than the first display unit  20 . However, the scope and spirit of the inventive concept may not be limited thereto. For example, the area of the second display unit  30  may be larger than that of the first display unit  20 .

         [0024]    According to an embodiment of the inventive concept, the playback content may be video content, and the display unit  41  may play the video content. However, the scope and spirit of the inventive concept may not be limited thereto. For example, the playback contents may play a variety of contents like music, picture or text. 
         [0025]    The second display unit  30  may change to either a first mode in a deactivated state or a second mode in an activated state. The first mode corresponding to the deactivated state may refer to a state in which only a tag  45  of the second display unit  30  to be described later is displayed on the first display unit  20 . The second mode corresponding to the activated state may refer to a state in which the second display unit  30  is displayed on the first display unit  20 . 
         [0026]    Meanwhile, when a user&#39;s touch is detected on the first display unit  20  while the second display unit  30  is in the second mode corresponding to the activated state, a mode of the second display unit  30  may be changed to a third mode corresponding to an unfocused state. 
         [0027]    In the third mode, brightness, chroma or opacity of the second display unit  30  may be decreased. For example, as illustrated in  FIG. 4 , the second display unit  30  may become dark, blurred, or transparent in the third mode corresponding to the unfocused state. 
         [0028]    Furthermore, in the first mode, the second display unit  30  may further include, for example, the tag  45  which is displayed on the first display unit  20  with the second display unit  30  deactivated. As illustrated in  FIG. 5 , in the first mode, the second display unit  30  may display only the tag  45  so as to be overlapped on the first display unit  20 . According to an embodiment of the inventive concept, the tag  45  may be displayed to be exposed on a bottom area of the first display unit  20 . However, the scope and spirit of the inventive concept may not be limited thereto. For example, the tag  45  may be displayed on a top, left, or right area of the first display unit  20 . 
         [0029]    Meanwhile, when dragging the tag  45  in the direction of the top of the first display unit  20  while only the tag  45  of the second display unit  30  is displayed to be overlapped on the first display unit  20 , the mode of the second display unit  30  may be changed to the second mode so as to be overlapped and displayed on the first display unit  20  as illustrated in  FIG. 3 . An embodiment of the inventive concept is exemplified as the mode of the second display unit  30  is changed to the second mode by dragging the tag  45 . However, the scope and spirit of the inventive concept may not be limited thereto. For example, the mode of the second display unit  30  may be changed to the second mode by clicking the tag  45  or by gesture motion. 
         [0030]    When a piece of content is selected from the first and second content lists  10  and  10 ′ which are outputted to the first display unit  20  while the second display unit  30  is in an invisible state as illustrated in  FIG. 2 , the contents playback system based on the dynamic layer according to an embodiment of the inventive concept may display the second display unit  30  as illustrated in  FIG. 3 . According to an embodiment of the inventive concept, for descriptive convenience, the content list may be limited to the first and second content lists  10  and  10 ′, but the number of content lists may not be limited thereto. 
         [0031]    Furthermore, the contents playback system based on the dynamic layer according to an embodiment of the inventive concept may output the first content list  10  and the second content list  10 ′, which is different from the first content list  10 , to the first display unit  20  while the display of the second display unit  30  is maintained. 
         [0032]    In the contents playback system based on the dynamic layer according to an embodiment of the inventive concept, when the second display unit  30  is clicked while the second display unit  30  is in the second mode, for example, while the second display unit  30  is in the activated state, the second display unit  30  may be displayed to be maximized. In this case, a size of the second display unit  30  may correspond to that of the first display unit  20 . 
         [0033]    In another embodiment, when the display unit  41  of the second display unit  30  is clicked while the second display unit is in the second mode, the display unit  41  of the second display unit  30  may be maximized in size so as to correspond to the first display unit  20 . Accordingly, the video being played may be watched through the whole display screen. 
         [0034]    An operation of the contents playback system based on the dynamic layer according to an embodiment of the inventive concept will be described based on such the configuration. 
         [0035]    As illustrated in  FIG. 2 , when the second display unit  30  is in the invisible state, there may be selected and clicked a piece of content to be played from the content lists  10  and  10 ′ which are outputted on the first display unit  20 . 
         [0036]    As illustrated in  FIG. 3 , as the content is clicked, the second display unit  30  on which the video and progress state corresponding to the clicked content are displayed may be displayed to be overlapped on the first display unit  20  and the mode of the second display unit  30  may be changed to the second mode corresponding to the activated state. 
         [0037]    Accordingly, the user may enjoy the video through the second display unit  30  which is overlapped on the first display unit  20 . 
         [0038]    Meanwhile, when the second display unit  30  is clicked, and more preferably, when the display unit  41  of the second display unit  30  is clicked, while the second display unit  30  is disposed to be overlapped on the first display unit, the display unit  41  of the second display unit  30  may be maximized to have a size corresponding to the first display unit  20 . Accordingly, the video being played may be watched through the whole display screen. 
         [0039]    Below, it will be described how to search for other contents while playing content using the contents playback system based on the dynamic layer according to an embodiment of the inventive concept. 
         [0040]    First of all, in an embodiment, when the user touches the first display unit  20 , with the second display unit  30  overlapped on the first display unit  20 , as illustrated in  FIG. 3 , the mode of the second display unit  30  may be changed to the third mode corresponding to the unfocused state while the second display unit  30  may become dark, blurred, or transparent. Accordingly, the content lists  10  and  10 ′ may be clearly displayed on the first display unit  20  as illustrated in  FIG. 4 . 
         [0041]    Accordingly, the user may easily search for content from the content lists  10  and  10 ′ displayed on the first display unit  20  in the state where the second display unit  30  is in the unfocused state. 
         [0042]    In another embodiment, as illustrated in  FIG. 3 , when the tag  45  is dragged, for example, in the direction of the bottom area of the first display unit  20  with the second display unit  30  overlapped on the first display unit  20 , as illustrated in  FIG. 5 , there may be performed switching to the first mode corresponding to the deactivated state in which the remaining area of the second display unit  30  other than the tag  45  is not displayed on the first display unit  20  and only the tag  45  is displayed on the bottom area of the first display unit  20 . 
         [0043]    Accordingly, the user may easily search for content from the content lists  10  and  10 ′ displayed on the first display unit  20 , with the second display unit  30  deactivated. 
         [0044]    As such, according to an embodiment of the inventive concept , a mode of the second display unit  30  which is disposed to be overlapped on the first display unit  20  which outputs the first content list and displays information of the playback content being played may switch to one of the first mode corresponding to the deactivated state and the second mode corresponding to the activated state, thereby making it possible to easily search for other contents, with information of the playback content displayed while playing content of the content list and increasing user convenience. 
         [0045]    Some embodiments of this disclosure provide a contents playback system based on a dynamic layer which is capable of easily searching for content, with information of playback content displayed while playing content of a content list and improving user convenience. 
         [0046]    While the inventive concept has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the inventive concept as defined by the appended claims and their equivalents.
