Embodiment Construction

[0028] figure 2 It is a control structure diagram related to the control structure used in the broadcasting terminal in the present invention to perform multimedia broadcasting receiving operations. Its structure includes: a converter 220, which converts the mode signal provided from the mobile communication terminal dedicated modem (MSM) 210, to generate a digital multimedia broadcasting reception mode signal; a field effect conversion transistor (FET) (Q), according to the above-mentioned 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] A general LCD mode and a DMB broadcast mode are provided in a digital multimedia broadcast receiving circuit (DMB SOC). It is not necessary to run DMB SOC when only normal LCD is output. At this time, when the clock driving DMBSOC is divided into LCD mode and DMB mode, and when a converter and FET structure a...

Abstract

A DMB(Digital Multimedia Broadcasting) terminal and a control method thereof is provided to prevent unnecessary current consumption in a DMB receiving system. A DMB(Digital Multimedia Broadcasting) terminal comprises an inverter and an FET(Field Effect Transistor,Q). The inverter converts a mode signal offered from an MSM(Mobile Station Modem) into a DMB receipt mode signal. The FET(Field Effect Transistor,Q) activates an operation of a DMB SOC(System On Chip) only in case of going into a DMB mode according to an output signal of the inverter. The inverter inverts a mode signal offered from the MSM.

Description

technical field [0001] The present invention relates to a digital multimedia broadcasting terminal and a terminal control method, more specifically, to a terminal and a control method capable of overall controlling a digital multimedia broadcasting receiving mode by using one control signal. Background technique [0002] The digitization of broadcasting has had an impact on past analog radio broadcasting, and has brought the arrival of digital radio broadcasting ahead of schedule. Moreover, not only the conventional voice broadcasting service can be provided, but also digital multimedia broadcasting (Digital Multimedia Broadcasting, DMB) including data transmission and multimedia service can be realized. Digital multimedia broadcasting has the advantages of transmission channel anti-noise, strong ability of distortion and interference, high transmission efficiency and the ability to provide various multimedia services. [0003] A terminal for receiving digital multimedia br...
