described in the section 6.2. The Composite_to_VGA block takes the video signals from the TV decoders as input and generate VGA-interfaced signals as output. The circuit in the FPGA is equipped with two Composite_to_VGA blocks converting the video signals from the TV decoder 1 and TV decoder 2 respectively. To display two video signals in PIP mode on the LCD/CRT monitor, the output VGA data rate of the Composite_to_VGA block for the sub window must be two times as fast as the rate of the Composite_to_VGA block for the main window. In addition, the output timing of the VGA interface signal from the Composite_to_VGA block is controlled by the pip_position_controller block that determines the stating poison of the sub window. Finally, both of the two VGA interfaced signals will be multiplexed and sent to the LCD/CRT monitor via the VGA_multiplexer block.
