In more detail, the scaler 408 is capable of processing YUV, YPbPr, and other video and HDTV signals in addition to RGB. To pass. The LVDS 409 outputs digital RGB.

In addition, the scaler 408 separates the input image data and provides a function of displaying two screens on one screen. For example, in order to simultaneously display data transmitted from the host PC to the RDP and TV data transmitted from the cradle, the RDP data of the host PC is directly displayed using a line buffer inside the scaler 408. The TV data is overlaid through the DRAM 414 which is a frame buffer of the scaler 408 and output to the LCD 410.

In addition, the scaler 408 is added to the OSD (On Screen Display) function to create a user interface (User Interface) using only a conventional video controller (Virtual Channel) on the host PC using an RDP virtual channel (Virtual Channel) The S / W module related to the UI is needed, but the OSD function of the scaler can be used to improve this, because it is not necessary.
