[0028] figure 2 It is a diagram of the control structure required for the multimedia broadcast receiving operation used in the broadcasting terminal in the present invention. Its structure includes: a converter 220, which converts the mode signal provided from a mobile communication terminal dedicated modem (MSM) 210 to generate a digital multimedia broadcasting reception mode signal; a field effect switching transistor (FET) (Q), according to the above converter The output signal of 220 can activate the operation of the digital multimedia broadcasting receiving circuit 230 only when entering the digital broadcasting mode.
[0029] Provides general LCD mode and DMB broadcast mode in the digital multimedia broadcast receiving circuit (DMB SOC). When only general LCD is output, there is no need to run DMB SOC. At this time, the clock driving DMBSOC is divided into LCD mode and DMB mode, and when the converter and FET structure are used for On / Off operation, it can be constructed to...
