Abstract

A digital multimedia broadcasting terminal is provided to use only one power supply source for each block and distribute the power to each block by means of a switching device. A core block(40) is operated at the start state of a terminal. An LDO(Low Drop Output voltage regulator)(10) supplies the power to the core block. A digital block(50) is driven at the waiting state of a communication service. An analog block(60) is operated when receiving the DMB data according to the DBM service and when displaying broadcasting contents corresponding to the DMB data. The DMB terminal includes the first switch(20). The first switch is driven so that the power is supplied to the digital block.

Description

technical field [0001] The invention belongs to digital multimedia broadcasting technology, in particular to a digital multimedia broadcasting terminal for efficiently distributing power. Background technique [0002] Digital Multimedia Broadcasting (DMB) is gradually becoming concrete. The concept of digital multimedia broadcasting is defined as digital multimedia broadcasting that can provide high-quality and high-quality audio / video services and data services and provide excellent fixed and mobile receiving quality. [0003] Conventional DMB terminals include such as figure 1 The three parts shown. [0004] figure 1 It is a diagram showing the division of components classified by operation in the digital multimedia broadcasting terminal according to the prior art. [0005] refer to figure 1 , the DMB terminal is composed of a core component 4 , a digital component 5 and an analog component 6 according to the actions of the terminal. [0006] Furthermore, the DMB ter...
