Description:
BACKGROUND 
       [0001]    The present invention relates to a video content display technique, and more specifically, the present invention discloses a method, a display and a computer readable medium for video content display control in an on screen display (OSD). 
         [0002]    The firms that wish to promote their product with advertisement always implement the content by themselves or just commission an advertisement vendor to do that for them. Before showing the advertisement, it needs digital signage display system and management software interface for displaying and scheduling. As shown in  FIG. 1 , the digital signage display system  1  consists of a client terminal  11 , a server  12 , a digital signage box  13  and a display  141  or  142 . The server  12  receives and combines a video content  161  and a subtitle  162  of client terminal  11  to form a video displayed in the display  141  or  142  later, characters such as source  151 , special effects  152 , font  153 , size  154  and color  155  are set in the management software interface  15 . The mentioned advertisement updates the content of the digital signage box  13  and then is displayed in one of the display  141  and  142 , such as a computer monitor, a TV and advertisement player in public place, or even in a public display system consisting of more display  141  and  142 . However, it increases the costs in system environment establishing and maintaining, and goes to the expense of affording the training fee and salary of system administrator. More, it also results in the indirect update and late response since the firm should inform the advertisement vendor for further parameter adjustment in the management software interface  15 . 
         [0003]    As shown in  FIG. 2 , an OSD  20  of a display  2  has a brightness adjustment item  211 , a contrast adjustment item  212 , a screen adjustment item  213 , an OSD setting item  214  and miscellaneous adjustment item  215 . A corresponding advanced item and an inputting zone of parameter value will pop up when a user selects one of the mentioned items. For instance, an OSD horizontal position adjustment item  221 , an OSD vertical position adjustment item  222  and an OSD language setting item  223  will be displayed for receiving the parameter value sent from an input device such as remote controller when the user select the OSD setting item  214 . Unfortunately, it still lacks of a direct way for user to perform the video content display control. 
         [0004]    Accordingly, the ordinary digital signage display system is controlled by an external and remote interface for parameter adjusting of the video content such as subtitle, and the content storing, updating and distributing should be done by equipping with an external sever box or a media box. It really increases the costs in many aspects and lacks of flexibility.
