본 발명에 따른 멀티미디어 데이터의 재생이 가능한 이동 단말기 및 이동 단말기의 멀티미디어 재생 방법은 다음과 같은 장점이 있다. The mobile terminal capable of reproducing multimedia data and the multimedia reproducing method of the mobile terminal according to the present invention have the following advantages.
본 발명에 따르면, 시간 지연을 최소화하여 멀티미디어 데이터를 제공할 수 있다. 예를 들면, 비용 및 속도 등을 기초로 하여 결정된 제1 통신망을 통하여 백그라운드로 멀티미디어 데이터를 미리 수신하여, 멀티미디어 데이터가 필요할 때 즉시 제공할 수 있다. According to the present invention, it is possible to provide multimedia data with minimal time delay. For example, the multimedia data may be received in advance in the background through a first communication network determined based on cost and speed, and the multimedia data may be immediately provided when needed.
또한, 수신 조건을 만족할 때 백그라운드로 멀티미디어 데이터를 수신하므로, 이동 단말기 사용자의 불편을 최소화할 수 있다. 예를 들면, 프로세서가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상일 경우, 제한 애플리케이션이 실행되지 않고 있을 경우 등의 수신 조건을 만족할 때 백그라운드로 멀티미디어 데이터를 수신하므로, 사용자는 데이터 수신을 체감하지 않을 수 있다.In addition, since multimedia data is received in the background when the reception condition is satisfied, inconvenience of the mobile terminal user can be minimized. For example, when the available resource ratio used by the processor is equal to or higher than the reference resource ratio, the multimedia data is received in the background when a reception condition such as when the restricted application is not running is received, so that the user may not feel the data reception. .

이하에서는, 첨부된 도면을 참조하여 본 발명에 따른 이동 단말기 및 멀티미디어 재생 방법의 바람직한 실시예를 상세히 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of a mobile terminal and a multimedia playback method according to the present invention.
도 1은 본 발명에 따른 이동 단말기를 도시한 블록도이다. 1 is a block diagram illustrating a mobile terminal according to the present invention.
도 1을 참조하면, 본 발명에 따른 이동 단말기는 저장 수단(200), 프로세서(100) 및 통신 수단(300)을 포함한다. Referring to FIG. 1, a mobile terminal according to the present invention includes a storage means 200, a processor 100, and a communication means 300.
프로세서(100)는 프로그램을 실행하며, 이동 단말기의 각 구성 요소를 제어한다. 구체적으로, 프로2세서는 저장 수단(200)에 저장된 멀티미디어 데이터를 처리하며, 프로그램에 포함된 인스트럭션을 실행한다. The processor 100 executes a program and controls each component of the mobile terminal. Specifically, the processor processes the multimedia data stored in the storage means 200 and executes instructions included in the program.
저장 수단(200)은 프로그램 및 멀티미디어 데이터를 저장하며, 프로세서(100)가 프로그램을 실행하는 데 필요한 리소스를 제공한다. 저장 수단(200)은 DRAM, flash ROM 등 다양한 소자를 포함할 수 있다. The storage means 200 stores the program and the multimedia data, and provides the resources necessary for the processor 100 to execute the program. The storage means 200 may include various devices such as DRAM and flash ROM.
통신 수단(300)은 프로세서(100)의 제어에 따라 통신망을 통하여 통신하며, 제1 통신망 및 제2 통신망을 통하여 통신할 수 있다. 통신 수단(300)은 무선 랜카드, 이동 통신 모듈 등 다양한 통신 모듈을 포함할 수 있다. The communication means 300 may communicate through a communication network under control of the processor 100, and may communicate through a first communication network and a second communication network. The communication means 300 may include various communication modules such as a wireless LAN card and a mobile communication module.
프로그램은, 도 2에 도시된 바와 같이, 제1 내지 제5 인스트럭션을 포함한다. The program includes first to fifth instructions, as shown in FIG.
이하에서는, 프로세서(100)가 프로그램을 실행하는 과정에 대하여 상세히 설명한다. Hereinafter, a process of executing a program by the processor 100 will be described in detail.
프로세서(100)는 제1 인스트럭션에 따라 제1 통신망을 통하여 통신이 가능한지 판단한다. The processor 100 determines whether communication is possible through the first communication network according to the first instruction.
제1 통신망은 근거리 무선망(예를 들면, 와이파이(Wi-Fi) 통신망)을 포함하는 것이 바람직하다. 제1 통신망이 와이파이 통신망인 경우, 프로세서(100)는 통신 수단(300)에 포함된 무선 랜카드를 제어하여 무선 접속 장치(AP, access point)와 데이터를 송수신한다. 와이파이 통신망은 사업자 또는 일반 사용자가 쉽게 구축할 수 있고 비교적 속도가 빠른 장점이 있지만, 무선 접속 장치의 서비스 영역이 비교적 좁은 단점이 있다. The first communication network preferably includes a local area network (eg, a Wi-Fi communication network). When the first communication network is a Wi-Fi communication network, the processor 100 controls a wireless LAN card included in the communication means 300 to transmit and receive data with an access point (AP). The Wi-Fi communication network can be easily constructed by a service provider or a general user and has a relatively high speed. However, a Wi-Fi communication network has a relatively narrow service area.
제2 통신망은 이동 통신망(예를 들면, 3G(3세대) 이동 통신망 또는 4G(4세대) 이동 통신망)을 포함하는 것이 바람직하다. 제2 통신망이 이동 통신망인 경우, 프로세서(100)는 통신 수단(300)에 포함된 이동 통신 모듈을 제어하여 기지국과 데이터를 송수신한다. 이동 통신망은 근거리 통신망에 비하여 서비스 영역에 대한 제한이 적은 장점이 있지만, 이동 통신 서비스를 이용하는 비용이 발생하고, 근거리 무선망에 비하여 속도가 느리다. The second communication network preferably includes a mobile communication network (eg, a 3G (3rd generation) mobile communication network or a 4G (4th generation) mobile communication network). When the second communication network is a mobile communication network, the processor 100 controls the mobile communication module included in the communication means 300 to transmit and receive data with the base station. Although the mobile communication network has an advantage of less restriction on the service area than the local area network, the mobile communication network incurs the cost of using the mobile communication service and is slower than the local area network.
이동 단말기는 제1 통신망 및 제2 통신망 중 적어도 하나를 통하여 통신할 수 있으며, 제1 통신망은 제2 통신망에 비하여 비용 및 속도 면에서 장점이 있다. 따라서 프로세서(100)는 먼저 제1 인스트럭션에 따라 제1 통신망을 통하여 통신이 가능한지 판단한다. The mobile terminal can communicate through at least one of the first communication network and the second communication network, and the first communication network has advantages in cost and speed compared to the second communication network. Therefore, the processor 100 first determines whether communication is possible through the first communication network according to the first instruction.
다음으로, 프로세서(100)는 제2 인스트럭션에 따라 제1 인스트럭션을 실행한 결과 제1 통신망을 통하여 통신할 수 있는 경우, 수신 조건을 만족하는지 판단한다. Next, when the processor 100 can communicate through the first communication network as a result of executing the first instruction according to the second instruction, the processor 100 determines whether the reception condition is satisfied.
수신 조건은 제1 통신망을 통하여 통신할 수 있는 경우, 백그라운드로 멀티미디어 데이터를 수신하기 위한 판단 기준이 된다.The reception condition may be a criterion for receiving multimedia data in the background when communication is possible through the first communication network.
이동 단말기는 데스크탑 컴퓨터, 노트북 컴퓨터 등에 비하여 프로세서(100)가 이용할 수 있는 자원이 적다. 또한, 이동 단말기는 무선으로 통신하므로, 유선 통신에 비하여 통신의 대역폭이 좁다. 따라서 이동 단말기는 복수의 작업을 동시에 수행하는 것(멀티태스킹, multitasking)을 최소화하는 것이 바람직하다. 프로세서(100)는 제2 인스트럭션에 따라 수신 조건을 만족하는지 판단하여 과도한 멀티태스킹을 방지할 수 있다. Mobile terminals have less resources available to the processor 100 than desktop computers, notebook computers, and the like. In addition, since the mobile terminal communicates wirelessly, the bandwidth of the communication is narrower than that of the wired communication. Accordingly, it is desirable for the mobile terminal to minimize a plurality of tasks simultaneously (multitasking). The processor 100 may determine whether a reception condition is satisfied according to the second instruction to prevent excessive multitasking.
먼저, 수신 조건은 프로세서(100)가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상이 되는 조건을 포함할 수 있다. 기준 리소스 비율은 프로세서(100)의 성능, 저장 수단(200)의 용량 등에 따라 결정되며, 제1 통신 수단(300)을 통하여 멀티미디어 데이터를 수신하는 것이 과부하를 일으키지 않는 기준이다. 프로세서(100)가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상인 경우, 백그라운드(background)로 제1 통신망을 통하여 멀티미디어 데이터를 수신하여도 이동 단말기의 사용자에게 불편을 끼치지 않는다. First, the reception condition may include a condition in which the available resource ratio used by the processor 100 becomes equal to or greater than the reference resource ratio. The reference resource ratio is determined according to the performance of the processor 100, the capacity of the storage means 200, and the like, and is a reference for receiving multimedia data through the first communication means 300 without causing an overload. When the available resource ratio used by the processor 100 is greater than or equal to the reference resource ratio, even if the multimedia data is received through the first communication network in the background, the user of the mobile terminal is not inconvenienced.
다음으로, 수신 조건은 제한 애플리케이션이 백그라운드 및 포어그라운드(foreground)로 실행되지 않은 조건을 포함할 수 있다. 제한 애플리케이션은 통신망의 가용 대역폭 또는 가용 리소스를 대부분 소모하는 애플리케이션이다. 예를 들면, 고해상도 동영상 스트리밍을 제공하는 애플리케이션, 컴퓨터를 원격 조정하는 애플리케이션은 제한 애플리케이션에 포함될 수 있다. Next, the reception condition may include a condition that the restriction application is not executed in the background and foreground. Restricted applications are applications that consume most of the available bandwidth or available resources of the network. For example, applications that provide high resolution video streaming and applications that remotely control a computer may be included in the restricted application.
다음으로, 수신 조건은 이동 단말기에 포함된 GPS 수신기 및 통신 수단(300) 중 어느 하나로부터 획득한 위치 좌표가 허용 영역 내에 포함되는 것을 포함할 수 있다. 제1 통신망이 와이파이 통신망인 경우를 예로 들면, 사용자의 가정이나 회사에서 이용하는 와이파이 통신망은 지하철에서 이용하는 와이파이 통신망보다 대역폭이 넓다. 따라서 제1 통신망을 원활하게 이용할 수 있는 위치를 중심으로 허용 영역을 설정하여 수신 조건을 제한할 수 있다. Next, the reception condition may include that the position coordinates obtained from any one of the GPS receiver and the communication means 300 included in the mobile terminal are included in the allowable area. For example, when the first communication network is a Wi-Fi communication network, a Wi-Fi communication network used in a user's home or company has a wider bandwidth than a Wi-Fi communication network used in a subway. Therefore, the reception condition may be limited by setting the allowable area around the position where the first communication network can be smoothly used.
프로세서(100)는 제3 인스트럭션에 따라 수신 조건을 만족하는 경우, 백그라운드로 제1 통신망을 통하여 멀티미디어 데이터를 수신한다. 즉, 이동 단말기는 비용 및 속도 등에서 장점을 가진 제1 통신망을 통하여 통신하고 가용 리소스가 충분한 경우, 멀티미디어 데이터를 미리 수신하여, 멀티미디어 데이터의 제공이 필요할 때 즉시 제공할 수 있다. When the reception condition is satisfied according to the third instruction, the processor 100 receives the multimedia data through the first communication network in the background. That is, when the mobile terminal communicates through a first communication network having advantages in cost and speed, and sufficient resources are available, the mobile terminal may receive multimedia data in advance and provide the multimedia data immediately when necessary.
프로세서(100)는 제4 인스트럭션에 따라 제2 통신망만을 통하여 통신이 가능한 경우, 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터를 재생하기 위한 재생 조건을 만족하는지 판단한다. 제1 통신망은 제2 통신망에 비하여 속도 및 비용 상의 장점을 가지므로, 제2 통신망만을 통하여 통신이 가능한 경우 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터를 재생할 실익이 있다. 재생 조건은 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터를 제공하기 위한 조건이다. When the communication is possible only through the second communication network according to the fourth instruction, the processor 100 determines whether a reproduction condition for reproducing the received multimedia data is executed by executing the third instruction. Since the first communication network has an advantage in speed and cost compared to the second communication network, when communication is possible only through the second communication network, it is advantageous to reproduce the multimedia data received by executing the third instruction. The reproduction condition is a condition for providing the received multimedia data by executing the third instruction.
먼저, 재생 조건은 제휴 애플리케이션이 실행되는 조건을 포함할 수 있다. 예를 들면, 멀티미디어 데이터가 광고 데이터인 경우, 제휴 애플리케이션이 실행되는 동안 광고를 재생함으로써, 시간 지연 없이 이동 단말기의 사용자에게 광고를 노출시킬 수 있다. First, the reproduction condition may include a condition under which the affiliated application is executed. For example, if the multimedia data is advertisement data, the advertisement can be displayed to the user of the mobile terminal without time delay by playing the advertisement while the affiliate application is executed.
또한, 재생 조건은 애플리케이션으로부터 재생 요청 정보를 수신하는 조건을 포함할 수 있다. 예를 들면, 애플리케이션이 게임 애플리케이션인 경우, 게임 애플리케이션은 게임의 레벨 변경 시에 광고의 재생을 요청하는 재생 요청 정보를 전송할 수 있다. 재생 요청 정보를 수신한 프로세서(100)는 수신된 멀티미디어 데이터를 즉시 제공하여 게임의 레벨이 변경되는 사이에 사용자에게 광고를 제공할 수 있다. In addition, the playback condition may include a condition for receiving playback request information from the application. For example, if the application is a game application, the game application may transmit play request information requesting the play of an advertisement upon changing the level of the game. Upon receiving the play request information, the processor 100 may immediately provide the received multimedia data to provide an advertisement to the user while the level of the game is changed.
프로세서(100)는 제4-1 서브인스트럭션에 따라 통신 수단(300)의 전송 속도에 기초하여 버퍼율을 결정할 수 있다. 버퍼율은 멀티미디어 데이터를 스트리밍(streaming)방식으로 전송할 때, 멀티미디어 데이터가 끊김없이 재생될 수 있는 비율이며, 통신 수단(300)의 전송 속도에 따라 결정된다. The processor 100 may determine the buffer rate based on the transmission speed of the communication means 300 according to the 4-1 subinstruction. The buffer rate is a rate at which multimedia data can be seamlessly reproduced when the multimedia data is transmitted in a streaming manner, and is determined according to the transmission speed of the communication means 300.
프로세서(100)는 제4-2 서브인스트럭션에 따라 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터의 수신율이 버퍼율 이상인지 판단한다. 프로세서(100)는 멀티미디어 데이터의 수신율이 버퍼율 이상인지 판단하여, 멀티미디어 데이터를 스트리밍 방식으로 전송할 때 끊김없이 재생할 수 있도록 한다. The processor 100 executes the third instruction according to the 4-2 sub-instruction to determine whether the reception rate of the received multimedia data is equal to or greater than the buffer rate. The processor 100 determines whether the reception rate of the multimedia data is greater than or equal to the buffer rate, so that the multimedia data can be seamlessly reproduced when the multimedia data is transmitted in a streaming manner.
프로세서(100)는 제5 인스트럭션에 따라 재생 조건을 만족하는 경우, 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터를 재생한다. 프로세서(100)는 인코딩(incoding)된 멀티미디어 데이터를 수신한 경우, 멀티미디어 데이터를 디코딩(decoding)하여 재생한다. When the playback condition is satisfied according to the fifth instruction, the processor 100 executes the third instruction to play the received multimedia data. When the processor 100 receives the encoded multimedia data, the processor 100 decodes and reproduces the multimedia data.
도 3은 본 발명에 따른 멀티미디어 재생 방법을 도시한 흐름도이다. 3 is a flowchart illustrating a multimedia playback method according to the present invention.
본 발명에 따른 영상 처리 방법은 도 1을 참조하여 설명한 이동 단말기에서 실행될 수 있다. The image processing method according to the present invention may be executed in the mobile terminal described with reference to FIG. 1.
도 3을 참조하면, 먼저, 제1 통신망을 통하여 통신이 가능한지 판단한다(S100). Referring to FIG. 3, first, it is determined whether communication is possible through the first communication network (S100).
제1 통신망은 근거리 무선망(예를 들면, 와이파이(Wi-Fi) 통신망)을 포함하는 것이 바람직하다. 제1 통신망이 와이파이 통신망인 경우, 프로세서(100)는 통신 수단(300)에 포함된 무선 랜카드를 제어하여 무선 접속 장치(AP, access point)와 데이터를 송수신한다. 와이파이 통신망은 사업자 또는 일반 사용자가 쉽게 구축할 수 있고 비교적 속도가 빠른 장점이 있지만, 무선 접속 장치의 서비스 영역이 비교적 좁은 단점이 있다. The first communication network preferably includes a local area network (eg, a Wi-Fi communication network). When the first communication network is a Wi-Fi communication network, the processor 100 controls a wireless LAN card included in the communication means 300 to transmit and receive data with an access point (AP). The Wi-Fi communication network can be easily constructed by a service provider or a general user and has a relatively high speed. However, a Wi-Fi communication network has a relatively narrow service area.
제2 통신망은 이동 통신망(예를 들면, 3G(3세대) 이동 통신망 또는 4G(4세대) 이동 통신망)을 포함하는 것이 바람직하다. 제2 통신망이 이동 통신망인 경우, 프로세서(100)는 통신 수단(300)에 포함된 이동 통신 모듈을 제어하여 기지국과 데이터를 송수신한다. 이동 통신망은 근거리 통신망에 비하여 서비스 영역에 대한 제한이 적은 장점이 있지만, 이동 통신 서비스를 이용하는 비용이 발생하고, 근거리 무선망에 비하여 속도가 느리다. The second communication network preferably includes a mobile communication network (eg, a 3G (3rd generation) mobile communication network or a 4G (4th generation) mobile communication network). When the second communication network is a mobile communication network, the processor 100 controls the mobile communication module included in the communication means 300 to transmit and receive data with the base station. Although the mobile communication network has an advantage of less restriction on the service area than the local area network, the mobile communication network incurs the cost of using the mobile communication service and is slower than the local area network.
이동 단말기는 제1 통신망 및 제2 통신망 중 적어도 하나를 통하여 통신할 수 있으며, 제1 통신망은 제2 통신망에 비하여 비용 및 속도 면에서 장점이 있다. 따라서 프로세서(100)는 먼저 S100단계에서 제1 통신망을 통하여 통신이 가능한지 판단한다. The mobile terminal can communicate through at least one of the first communication network and the second communication network, and the first communication network has advantages in cost and speed compared to the second communication network. Therefore, the processor 100 first determines whether communication is possible through the first communication network in step S100.
다음으로, S100 단계를 수행한 결과 제1 통신망을 통하여 통신할 수 있는 경우, 수신 조건을 만족하는지 판단한다(S200). Next, when it is possible to communicate via the first communication network as a result of performing step S100, it is determined whether the reception condition is satisfied (S200).
수신 조건은 제1 통신망을 통하여 통신할 수 있는 경우, 백그라운드로 멀티미디어 데이터를 수신하기 위한 판단 기준이 된다.The reception condition may be a criterion for receiving multimedia data in the background when communication is possible through the first communication network.
이동 단말기는 데스크탑 컴퓨터, 노트북 컴퓨터 등에 비하여 프로세서(100)가 이용할 수 있는 자원이 적다. 또한, 이동 단말기는 무선으로 통신하므로, 유선 통신에 비하여 통신의 대역폭이 좁다. 따라서 이동 단말기는 복수의 작업을 동시에 수행하는 것(멀티태스킹, multitasking)을 최소화하는 것이 바람직하다. 프로세서(100)는 제2 인스트럭션에 따라 수신 조건을 만족하는지 판단하여 과도한 멀티태스킹을 방지할 수 있다. Mobile terminals have less resources available to the processor 100 than desktop computers, notebook computers, and the like. In addition, since the mobile terminal communicates wirelessly, the bandwidth of the communication is narrower than that of the wired communication. Accordingly, it is desirable for the mobile terminal to minimize a plurality of tasks simultaneously (multitasking). The processor 100 may determine whether a reception condition is satisfied according to the second instruction to prevent excessive multitasking.
도 4는 본 발명에 따른 S200 단계의 일례를 도시한 흐름도이다. 4 is a flowchart illustrating an example of step S200 according to the present invention.
도 4를 참조하면, 수신 조건은 프로세서(100)가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상이 되는 조건을 포함할 수 있다(S210). 기준 리소스 비율은 프로세서(100)의 성능, 저장 수단(200)의 용량 등에 따라 결정되며, 제1 통신 수단(300)을 통하여 멀티미디어 데이터를 수신하는 것이 과부하를 일으키지 않는 기준이다. 프로세서(100)가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상인 경우, 백그라운드(background)로 제1 통신망을 통하여 멀티미디어 데이터를 수신하여도 이동 단말기의 사용자에게 불편을 끼치지 않는다. Referring to FIG. 4, the reception condition may include a condition in which the available resource ratio used by the processor 100 becomes equal to or greater than the reference resource ratio (S210). The reference resource ratio is determined according to the performance of the processor 100, the capacity of the storage means 200, and the like, and is a reference for receiving multimedia data through the first communication means 300 without causing an overload. When the available resource ratio used by the processor 100 is greater than or equal to the reference resource ratio, even if the multimedia data is received through the first communication network in the background, the user of the mobile terminal is not inconvenienced.
다음으로, 수신 조건은 제한 애플리케이션이 백그라운드 및 포어그라운드(foreground)로 실행되지 않은 조건을 포함할 수 있다(S220). 제한 애플리케이션은 통신망의 가용 대역폭 또는 가용 리소스를 대부분 소모하는 애플리케이션이다. 예를 들면, 고해상도 동영상 스트리밍을 제공하는 애플리케이션, 컴퓨터를 원격 조정하는 애플리케이션은 제한 애플리케이션에 포함될 수 있다. Next, the reception condition may include a condition in which the restricted application is not executed in the background and foreground (S220). Restricted applications are applications that consume most of the available bandwidth or available resources of the network. For example, applications that provide high resolution video streaming and applications that remotely control a computer may be included in the restricted application.
다음으로, 수신 조건은 이동 단말기에 포함된 GPS 수신기 및 통신 수단(300) 중 어느 하나로부터 획득한 위치 좌표가 허용 영역 내에 포함되는 것을 포함할 수 있다(S230). 제1 통신망이 와이파이 통신망인 경우를 예로 들면, 사용자의 가정이나 회사에서 이용하는 와이파이 통신망은 지하철에서 이용하는 와이파이 통신망보다 대역폭이 넓다. 따라서 제1 통신망을 원활하게 이용할 수 있는 위치를 중심으로 허용 영역을 설정하여 수신 조건을 제한할 수 있다. Next, the reception condition may include that the position coordinates obtained from any one of the GPS receiver and the communication means 300 included in the mobile terminal are included in the allowable area (S230). For example, when the first communication network is a Wi-Fi communication network, a Wi-Fi communication network used in a user's home or company has a wider bandwidth than a Wi-Fi communication network used in a subway. Therefore, the reception condition may be limited by setting the allowable area around the position where the first communication network can be smoothly used.
다시 도 3을 참조하면, S200 단계에서 수신 조건을 만족하는 경우, 백그라운드로 제1 통신망을 통하여 멀티미디어 데이터를 수신한다(S300). 즉, 이동 단말기는 비용 및 속도 등에서 장점을 가진 제1 통신망을 통하여 통신하고 가용 리소스가 충분한 경우, 멀티미디어 데이터를 미리 수신하여, 멀티미디어 데이터의 제공이 필요할 때 즉시 제공할 수 있다. Referring back to FIG. 3, when the reception condition is satisfied in step S200, multimedia data is received through the first communication network in the background (S300). That is, when the mobile terminal communicates through a first communication network having advantages in cost and speed, and sufficient resources are available, the mobile terminal may receive multimedia data in advance and provide the multimedia data immediately when necessary.
다음으로, 제2 통신망만을 통하여 통신이 가능한 경우, S300 단계에서 수신된 멀티미디어 데이터를 재생하기 위한 재생 조건을 만족하는지 판단한다(S400). 제1 통신망은 제2 통신망에 비하여 속도 및 비용 상의 장점을 가지므로, 제2 통신망만을 통하여 통신이 가능한 경우 제3 인스트럭션을 실행하여 수신한 멀티미디어 데이터를 재생할 실익이 있다. 재생 조건은 S300 단계에서 수신된 멀티미디어 데이터를 제공하기 위한 조건이다. Next, when communication is possible only through the second communication network, it is determined whether a reproduction condition for reproducing the multimedia data received in step S300 is satisfied (S400). Since the first communication network has an advantage in speed and cost compared to the second communication network, when communication is possible only through the second communication network, it is advantageous to reproduce the multimedia data received by executing the third instruction. The playback condition is a condition for providing the multimedia data received in step S300.
먼저, 재생 조건은 제휴 애플리케이션이 실행되는 조건을 포함할 수 있다. 예를 들면, 멀티미디어 데이터가 광고 데이터인 경우, 제휴 애플리케이션이 실행되는 동안 광고를 재생함으로써, 시간 지연 없이 이동 단말기의 사용자에게 광고를 노출시킬 수 있다. First, the reproduction condition may include a condition under which the affiliated application is executed. For example, if the multimedia data is advertisement data, the advertisement can be displayed to the user of the mobile terminal without time delay by playing the advertisement while the affiliate application is executed.
또한, 재생 조건은 애플리케이션으로부터 재생 요청 정보를 수신하는 조건을 포함할 수 있다. 예를 들면, 애플리케이션이 게임 애플리케이션인 경우, 게임 애플리케이션은 게임의 레벨 변경 시에 광고의 재생을 요청하는 재생 요청 정보를 전송할 수 있다. 재생 요청 정보를 수신한 프로세서(100)는 수신된 멀티미디어 데이터를 즉시 제공하여 게임의 레벨이 변경되는 사이에 사용자에게 광고를 제공할 수 있다. In addition, the playback condition may include a condition for receiving playback request information from the application. For example, if the application is a game application, the game application may transmit play request information requesting the play of an advertisement upon changing the level of the game. Upon receiving the play request information, the processor 100 may immediately provide the received multimedia data to provide an advertisement to the user while the level of the game is changed.
도 5는 S400 단계의 일례를 도시한 흐름도이다. 5 is a flowchart illustrating an example of step S400.
도 5를 참조하면, 통신 수단(300)의 전송 속도에 기초하여 버퍼율을 결정할 수 있다(S410). 버퍼율은 멀티미디어 데이터를 스트리밍(streaming)방식으로 전송할 때, 멀티미디어 데이터가 끊김 없이 재생될 수 있는 비율이며, 통신 수단(300)의 전송 속도에 따라 결정된다. Referring to FIG. 5, the buffer rate may be determined based on the transmission speed of the communication means 300 (S410). The buffer rate is a rate at which multimedia data can be reproduced without interruption when the multimedia data is transmitted in a streaming method, and is determined according to the transmission speed of the communication means 300.
다음으로, S300 단계에서 수신한 멀티미디어 데이터의 수신율이 버퍼율 이상인지 판단한다(S420). 프로세서(100)는 멀티미디어 데이터의 수신율이 버퍼율 이상인지 판단하여, 멀티미디어 데이터를 스트리밍 방식으로 전송할 때 끊김없이 재생할 수 있도록 한다. Next, it is determined whether the reception rate of the multimedia data received in step S300 is greater than or equal to the buffer rate (S420). The processor 100 determines whether the reception rate of the multimedia data is greater than or equal to the buffer rate, so that the multimedia data can be seamlessly reproduced when the multimedia data is transmitted in a streaming manner.
다시 도 3을 참조하면 S400 단계에서 재생 조건을 만족하는 경우, S300 단계에서 수신한 멀티미디어 데이터를 재생한다(S500). 프로세서(100)는 인코딩된 멀티미디어 데이터를 수신한 경우, 멀티미디어 데이터를 디코딩하여 재생한다. Referring to FIG. 3 again, if the playback condition is satisfied in step S400, the multimedia data received in step S300 is played (S500). When the processor 100 receives the encoded multimedia data, the processor 100 decodes and reproduces the multimedia data.
비록 본 발명의 실시예가 구체적으로 설명되었지만, 이는 단지 본 발명을 예시적으로 설명한 것에 불과한 것으로, 본 발명이 속하는 기술분야에서 통상의 지식을 가지는 자라면 본 발명의 본질적인 특성에서 벗어나지 않는 범위 내에서 다양한 변형이 가능할 것이다. Although embodiments of the present invention have been described in detail, these are merely illustrative of the present invention, and those skilled in the art will appreciate that various changes can be made without departing from the essential features of the present invention. Modifications may be possible.
따라서 본 명세서에 개시된 실시예들은 본 발명을 한정하기 위한 것이 아니라 설명하기 위한 것이고, 이러한 실시예에 의하여 본 발명의 사상과 범위가 한정되는 것은 아니다. Therefore, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments.
발명의 범위는 아래의 청구범위에 의해 해석되어야 하며, 그와 동등한 범위 내에 있는 모든 기술은 본 발명의 권리범위에 포함되는 것으로 해석되어야 할 것이다.It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto will be construed as being included in the scope of the present invention.
본 발명에 따른 멀티미디어 데이터의 재생이 가능한 이동 단말기 및 이동 단말기의 멀티미디어 재생 방법은 다음과 같은 장점이 있다. The mobile terminal capable of reproducing multimedia data and the multimedia reproducing method of the mobile terminal according to the present invention have the following advantages.
본 발명에 따르면, 시간 지연을 최소화하여 멀티미디어 데이터를 제공할 수 있다. 예를 들면, 비용 및 속도 등을 기초로 하여 결정된 제1 통신망을 통하여 백그라운드로 멀티미디어 데이터를 미리 수신하여, 멀티미디어 데이터가 필요할 때 즉시 제공할 수 있다. According to the present invention, it is possible to provide multimedia data with minimal time delay. For example, the multimedia data may be received in advance in the background through a first communication network determined based on cost and speed, and the multimedia data may be immediately provided when needed.
또한, 수신 조건을 만족할 때 백그라운드로 멀티미디어 데이터를 수신하므로, 이동 단말기 사용자의 불편을 최소화할 수 있다. 예를 들면, 프로세서가 이용하는 가용 리소스 비율이 기준 리소스 비율 이상일 경우, 제한 애플리케이션이 실행되지 않고 있을 경우 등의 수신 조건을 만족할 때 백그라운드로 멀티미디어 데이터를 수신하므로, 사용자는 데이터 수신을 체감하지 않을 수 있다.In addition, since multimedia data is received in the background when the reception condition is satisfied, inconvenience of the mobile terminal user can be minimized. For example, when the available resource ratio used by the processor is equal to or higher than the reference resource ratio, the multimedia data is received in the background when a reception condition such as when the restricted application is not running is received, so that the user may not feel the data reception. .
