Date processing unit transfers the signals from interfaces to standard signal ,which realizes the COFDM preprocessing.
COFDM modulating unite modulates the date stream to spectrum signal. IF modulating output is the IF signal which can be adjustable in the 35-37 MHz frequency.
RF modulating unite changes the IF to 48-860MHz TV channels. CPU/LCD/LED/keyboard finishes the keyboard input, LED display and intelligent control
