Embodiment Construction

[0023] Hereinafter, preferred embodiments of the present invention are described in detail with reference to the accompanying drawings. The same reference numerals designate the same or corresponding elements in the figures. For clarity and conciseness, some structures or processes that are known in the art may not be described.

[0024] FIG. 1 is a diagram of a mobile broadcasting system to which the present invention is applied. Referring to FIG. 1, a DMB transmission center 300 transmits a DMB signal received from a broadcasting station (not shown). The wireless communication device 100, such as a DMB receiver, receives a DMB signal from the DMB transmission center 300, and outputs video and audio data through signal processing. The wireless communication device 100 is not limited to a DMB receiver, and may be other portable or vehicle-mounted terminals having a DMB receiving function. The earphone 200 communicates with the wireless communication device 100 using Bluetoo...

Abstract

Provided is a wireless communication device for receiving a mobile broadcasting signal and transmitting / receiving a Bluetooth(R) signal through a single antenna, which allows separation of the two signals using a difference in their frequency bands. A diplexer separates the signals using different band-pass filters. The signals are respectively input into a mobile broadcasting module and a Bluetooth(R) module. The wireless communication device allows reception of mobile broadcasting and Bluetooth signals within different frequency bands through a single antenna, thus achieving a compact and thin device with a reduced antenna mounting space.

Description

technical field [0001] The present invention relates to a mobile broadcast technology, and more specifically, to a wireless communication device for receiving mobile broadcast signals and sending / receiving bluetooth signals through a single antenna. Background technique [0002] Recently, there has been substantial competition to develop services and technologies related to mobile multimedia broadcasting. Mobile multimedia broadcasting is a new service that combines the advantages of both broadcasting and mobile communication with mobile communication technology. [0003] The European mobile broadcasting technology called DVB-H (Digital Video Broadcasting Handheld) and the American mobile broadcasting technology called MediaFLO are aimed at commercialization in the near future. Korea's Satellite Digital Multimedia Broadcasting (S-DMB) technology has already begun commercialization. The world's first terrestrial DMB (T-DMB) broadcast service has also been launched in Korea ...
