본 발명은 이동통신단말기에 관한 것으로, 특히 단말기를 통해 디지털 멀티미디어 방송(Digital Multimedia Broadcasting)과 같은 방송을 시청할 수 있는 이 동통신단말기에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal capable of watching a broadcast such as digital multimedia broadcasting (Digital Multimedia Broadcasting) through the terminal.
오늘날 정보통신 분야의 눈부신 발전으로, 정보 및 통신 환경의 급격한 변화를 맞이하고 있는데, 그와 같은 변화 중 이동통신단말기는 현대 사회에서 필수품으로 생각되어질 만큼 많이 사용되어지고 있다. 이와 같은 이동통신단말기의 저변확대에 따른 수요자들의 요구로 인해, 이동통신단말기에는 일반적 음성통화 이외에 더욱 다양한 기능이 부가되고 있다.Today, due to the remarkable development of the information and communication field, the information and communication environment is undergoing a drastic change, and among these changes, mobile communication terminals are being used as many as a necessity in modern society. Due to the demands of consumers due to the expansion of the mobile communication terminal, various functions are added to the mobile communication terminal in addition to the general voice call.
한편, 최근 CD, DVD 등 뛰어난 음질이 디지털 오디오 기기가 급격히 보급되어 보편화되면서 고급 음질을 요구하는 디지털 방송에 대한 청취자의 요구가 날로 증가하고 있으며, 이에 따라 기존의 FM 방송이 제공할 수 있는 음질의 한계를 극복하기 위해, 유럽, 캐나다, 미국 등에서 디지털 오디오 방송(Digital Audio Broadcasting; DAB)을 시행하고 있다. 상기 DAB 시스템은 현재의 AM 방송이나 FM 방송과는 전혀 다른 기술을 이용해, 고품질의 음질뿐만 아니라 이동 중에도 뛰어난 수신 능력을 보여주며, 영상이나 문자와 같은 디지털 데이터도 고속으로 송신할 수 있는 특성을 가지고 있다. 요즘에는 오디오 방송보다는 영상을 포함한 다양한 멀티미디어 서비스를 강조하여 디지털 멀티미디어 방송(DMB)이라 부른다.On the other hand, as digital audio devices are widely used in recent years with excellent sound quality such as CDs and DVDs, the demand for listeners for digital broadcasts requiring high quality sound is increasing day by day. To overcome the limitations, Digital Audio Broadcasting (DAB) is being implemented in Europe, Canada and the United States. The DAB system uses a completely different technology from the current AM or FM broadcasts to show not only high quality sound quality but also excellent reception performance on the go, and has a characteristic of transmitting digital data such as video and text at high speed. have. Nowadays, it is called digital multimedia broadcasting (DMB) by emphasizing various multimedia services including video rather than audio broadcasting.
최근에는 DMB를 시청할 수 있는 방송용 이동통신단말기가 소개되어 점점 보급화 추세에 있다. 그러나, 현재로는 하나의 방송채널만을 선택하여 시청할 수 있는 방송용 이동통신단말기가 소개되고 있다.Recently, a broadcasting mobile communication terminal capable of watching DMB has been introduced, which is becoming more and more popular. However, at present, a broadcast mobile communication terminal capable of selecting and viewing only one broadcast channel has been introduced.
본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 2이상의 방송채 널을 동시에 시청할 수 있는 이동통신단말기를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a mobile communication terminal capable of simultaneously watching two or more broadcast channels.
상기 목적을 달성하기 위해 본 발명은, 2개 이상의 디스플레이창, 및 상기 디스플레이창 갯수에 대응하는 방송채널을 독립적으로 동시에 수신할 수 있는 방송모듈을 포함하는 방송용 이동통신단말기를 제공한다.In order to achieve the above object, the present invention provides a broadcast mobile communication terminal comprising two or more display windows, and a broadcast module capable of independently and simultaneously receiving broadcast channels corresponding to the number of display windows.
이하 상기 목적을 구체적으로 구현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. 도면 전체에 걸쳐 동일한 구성요소는 설명의 편의상 동일한 도면부호를 부여한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically implement the above object will be described. Like reference numerals designate like elements throughout the drawings.
본 발명은 2개 이상의 디스플레이창을 가진 방송용 이동통신단말기라면 그 기종 또는 타입에 상관없이 다 적용될 수 있다. 그러나, 이하에서는 설명의 편의를 위해 도 1a 및 도 1b에서 도시된 바와 같은 2개의 디스플레이창을 가진 폴더형 DMB용 이동통신단말기를 예로 들어 본 발명의 일실시예를 설명하겠다. 본 발명의 범주가 이하의 설명에 의해 한정되어서는 아니됨을 명심하여야 한다.The present invention may be applied to any broadcast mobile communication terminal having two or more display windows regardless of the type or type thereof. However, hereinafter, for convenience of description, an embodiment of the present invention will be described by taking a folding type DMB mobile communication terminal having two display windows as shown in FIGS. 1A and 1B as an example. It should be noted that the scope of the present invention should not be limited by the following description.
먼저 도 1a 및 도 1b를 참조하면, 본 발명의 일실시예에 따른 이동통신단말기(1)는 2개의 디스플레이창, 즉 서브디스플레이창(10) 및 메인디스플레이창(20)을 갖는다. 상기 2개의 디스플레이창(10, 20)은 각각 다른 방송채널을 동시에 디스플레이하기 위한 것이다. 1A and 1B, a
서브디스플레이창(10)을 통해 시청할 채널은 서브디스플레이창(10) 하단의 MOD Key(15)를 이용하여 선택될 수 있도록 구성되는 것이 바람직하다. 또한, 메인디스플레이창(20)을 통해 시청할 채널은 키패드 상의 멀티키(25)를 이용하여 선택 될 수 있도록 구성되는 것이 바람직하다.The channel to be viewed through the
그리고, 서브디스플레이창의 방송 오디오 및 메인디스플레이창의 방송 오디오 중 어느 하나가 스피커 또는 이어폰을 통해 나오도록 구성될 수 있다. 오디오 선택 및 오디오 볼륨도 상기 MOD Key(15) 또는 멀티키(25)를 통해 조절되도록 구성될 수 있다. 이어폰을 통해 오디오를 듣는 경우, 양쪽 이어폰 각각에 서로 다른 방송채널의 오디오가 나오도록 구성될 수도 있다.Then, any one of the broadcast audio of the sub-display window and the broadcast audio of the main display window may be configured to come out through the speaker or the earphone. Audio selection and audio volume may also be configured to be adjusted via the
도 2를 참조하여 본 발명의 일실시예에 대해 더욱 구체적으로 살펴보면 다음과 같다. Looking at more specifically with respect to an embodiment of the present invention with reference to FIG.
이동통신단말기(1)의 DMB모듈(30)은 두 개의 모듈, 즉 제 1 모듈(33) 및 제 2 모듈(37)로 구성된다. 따라서, DMB모듈(30)은 각각 다른 2개의 방송 채널을 동시에 수신할 수 있다. The
제 1 모듈(33)에서 수신된 방송은 서브디스플레이창(10)으로 보내져서 디스플레이되고, 제 2 모듈(37)에서 수신된 방송은 메인디스플레이창(20)으로 보내져서 디스플레이된다. 제 1 모듈(33) 및 제 2 모듈(37)에서의 방송채널 선택은 사용자 인터페이스(즉, MOD Key(15) 및/또는 멀티키(25)) 및 제어모듈(40)을 통해 행해진다.The broadcast received at the
이러한 구성을 통해, 단말기 사용자는 사용자 인터페이스를 통해 2개의 디스플레이창을 통해 서로 다른 방송 채널을 시청할 수 있다. Through this configuration, the terminal user can watch different broadcast channels through the two display windows through the user interface.
본 발명은 본 발명의 정신 및 필수적 특징을 벗어나지 않는 범위에서 다른 특정한 형태로 구체화될 수 있음은 당업자에게 자명하다. 예컨대, 상기에서는 2개 의 방송채널을 독립적으로 시청할 수 있는 방송용 이동통신단말기에 대해 설명하였지만, 본 기술분야의 당업자라면 상기의 일실시예를 3개 이상의 방송채널을 독립적으로 시청할 수 있는 방송용 이동통신단말기로 변형하는 것은 매우 용이할 것이다. 또한, 상기에서는 2개의 방송채널을 시청하는 것에 대해서 서술하였으나, 상기 방송용 이동통신단말기를 통해 반드시 2개의 방송채널을 항시 동시에 시청하여야 하는 것은 아니고, 1개의 방송채널만을 시청하는 것도 물론 가능하다.It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. For example, although the above description has been given of a broadcast mobile communication terminal capable of viewing two broadcast channels independently, those skilled in the art will appreciate that one embodiment of the present invention is a broadcast mobile communication capable of independently viewing three or more broadcast channels. It will be very easy to transform into a terminal. In addition, although the above description has been given of watching two broadcast channels, it is not necessary to always watch two broadcast channels at the same time through the broadcast mobile communication terminal, but it is also possible to watch only one broadcast channel.
따라서, 상기의 상세한 설명은 모든 면에서 제한적으로 해석되어서는 아니되고 예시적인 것으로 고려되어야 한다. 본 발명의 범위는 첨부된 청구항의 합리적 해석에 의해 결정되어야 하고, 본 발명의 등가적 범위 내에서의 모든 변경은 본 발명의 범위에 포함된다.Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
본 발명에 의하면, 하나의 방송용 이동통신단말기를 통해 2개 이상의 방송채널을 동시에 시청할 수 있다. 따라서, 본 발명을 이용하면 2명 이상의 시청자가 하나의 방송용 이동통신단말기를 통해 서로 다른 방송채널을 동시에 시청할 수 있다는 장점이 있다.According to the present invention, two or more broadcast channels can be simultaneously viewed through one broadcast mobile communication terminal. Therefore, the present invention has the advantage that two or more viewers can simultaneously watch different broadcast channels through one broadcast mobile communication terminal.
