Description

디지털 티브이의 이더넷 장치{ETHERNET APPARATUS FOR DIGITAL TELEVISION}ETHERNET APPARATUS FOR DIGITAL TELEVISION

본 발명은 디지털 티브이의 이더넷 장치에 관한 것으로, 특히 동작중인 디지털 티브이 시스템의 메인보드에 전원차단 없이 부착하여 파일 전송 및 시스템 모니터링을 수행할 수 있도록 하는 디지털 티브이의 이더넷 장치에 관한 것이다.The present invention relates to an Ethernet device of a digital TV, and more particularly, to an Ethernet device of a digital TV which can be attached to a main board of a digital TV system in operation without powering off to perform file transfer and system monitoring.

차세대 디지털 티브이는 다양한 부가 기능을 겸비하고, 각종 통신 환경에 대처하기 위해서 매우 다양한 기능 모듈들을 포함하여 구성되는데, 이때 각각의 모듈들은 시스템 개발 단계에서 디버깅 장치를 통하여 액세스가 가능하도록 되어있다.The next generation digital TV has various additional functions and includes a wide variety of functional modules to cope with various communication environments, each of which is accessible through a debugging device at the system development stage.

일반적으로, 상기와 같은 디버깅 및 모니터링은 직렬 통신 포트(RS-232 포트)를 통해 이루어지게 되며, 보다 빠른 네트워크 인터페이스가 요구되는 경우에는 시스템의 메인 보드에 이더넷 모듈을 온-보드(on-board)시키는 경우도 있다.In general, such debugging and monitoring is performed through the serial communication port (RS-232 port), and if a faster network interface is required, the Ethernet module on-board the system's main board. In some cases.

그런데, 디지털 티브이 시스템은 매우 많은 기능 모듈로 구성되어 있기 때문에 개발 단계에서는 여러 사람이 시스템에 액세스하여 각 기능 모듈을 하드웨어/소프트웨어적으로 테스트를 수행하게 되는데, 이때 상기 직렬 통신 포트를 이용할 경우는 여러 사람이 동시에 한 시스템을 모니터링할 수 없을 뿐만 아니라, 통신 속도가 느려 테스트 시간이 길어지게 되며 이더넷 모듈을 온-보드 시키는 경우에는 여러 사람이 동시에 액세스가 가능하고 통신 속도도 빠르지만 그 만큼 시스템 제작 단가를 상승시키고 회로 구성 면적이 커지게 되는 문제점이 있었다.However, since the digital TV system is composed of a large number of functional modules, in the development stage, several people access the system and test each functional module by hardware / software. In this case, when using the serial communication port, Not only can humans not monitor a system at the same time, but the communication speed is slow, so the test time is long, and if the Ethernet module is on-board, several people can access simultaneously and the communication speed is high, but the system manufacturing cost There is a problem that the rise and the circuit configuration area becomes large.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출한 것으로, 시스템의 동작 여부에 관계없이 필요시에만 착탈이 가능하도록 하고, 디지털 티브이 시스템의 개발 단계에서만 요구되는 이더넷 모듈의 특성은 그대로 이용하면서 시스템의 제작 단가는 상승시키지 않도록 하기 위한 디지털 티브이의 이더넷 장치를 제공함에 그 목적이 있다.Therefore, the present invention was created to solve the above-mentioned conventional problems, and can be attached and detached only when necessary regardless of the operation of the system, and the characteristics of the Ethernet module required only in the development stage of the digital TV system are intact. The purpose of the present invention is to provide an Ethernet device of a digital TV so as not to increase the manufacturing cost of the system.

이하, 본 발명에 따른 일실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 의한 이더넷 장치의 구성을 보인 블록도로서, 이에 도시한 바와 같이 메인 시스템과 인터페이스하기 위한 커넥터부(10)와; 데이터를 이더넷에 적합한 데이터 전송 포맷으로 변환하는 이더넷 컨트롤러(20)와; 각 구성부가 원활히 연결되도록 하는 글루(Glue) 로직부(30)와; 메인 보드에 부착 후 이더넷 장치를 초기화 시키기 위한 리셋 구동부(40)와; 본 이더넷 장치를 터미널로 사용하여 제어하기 위한 통신부(50)를 포함하여 구성한 것으로, 이하 상기와 같이 구성한 본 발명의 동작 및 작용을 첨부된 도면을 참조하여 설명하면 다음과 같다.1 is a block diagram showing the configuration of an Ethernet device according to the present invention, and as shown therein, a connector unit 10 for interfacing with a main system; An Ethernet controller 20 for converting data into a data transmission format suitable for Ethernet; A glue logic unit 30 for smoothly connecting each component unit; A reset driver 40 for initializing the Ethernet device after attaching to the main board; The Ethernet device is configured to include a communication unit 50 for controlling by using the terminal. Hereinafter, the operation and operation of the present invention configured as described above will be described with reference to the accompanying drawings.

먼저, 도2는 본 발명에 의한 이더넷 장치와 메인 보드간에 상호 인터페이스되는 신호들을 보인 예시도로서, 메인 보드측에서는 어드레스(Address[0:5])와 입/출력 관련 신호(Read/Write, Chip Select, Out Enable, Sys_Reset) 및 전원(+5V, +3.3V, GND) 등이 출력되고, 본 발명 이더넷 장치에서는 그에 대한 응답 신호(Ready) 및 인터럽트 신호(Interrupt) 와 데이터(Data[0:7]) 등을 출력하게 된다.First, Figure 2 is an exemplary view showing signals that are interfaced between the Ethernet device and the main board according to the present invention, the address (Address [0: 5]) and the input / output related signals (Read / Write, Chip Select on the main board side) , Out Enable, Sys_Reset) and power (+ 5V, + 3.3V, GND), etc. are outputted. In the Ethernet device of the present invention, a response signal (Ready), an interrupt signal (Interrupt) and data (Data [0: 7]) ) And so on.

여기서, 상기 리셋 구동부(40)는 본 장치가 메인 시스템에 부착되어 전원을 인가받는 수간 내부 리셋회로에 의하여 소정시간(약 350ms) 동안 리셋 신호를 발생시키는데, 이는 이더넷 모듈이 커넥터를 통하여 접속될 때 발생하는 전원의 불안정으로 인한 회로의 이동동작을 방지하는 역할을 한다.Here, the reset driver 40 generates a reset signal for a predetermined time (about 350 ms) by an internal inter-circuit reset circuit to which the apparatus is attached to the main system and is powered, which is when the Ethernet module is connected through the connector. It prevents the movement of the circuit due to the instability of the generated power.

즉, 도3의 (a)에 도시한 바와 같이 본 장치가 메인 시스템에 접속됨과 동시에 전원(+3.3V)이 공급되면('하이'레벨) 이에 따라 리셋 구동부(40)에서 자체적으로 소정시간 동안 리셋 신호(Ethernet Reset Source#)가 출력되어('로우'레벨) 본 장치를 초기화 시키게 된다.That is, as shown in (a) of FIG. 3, when the device is connected to the main system and power (+ 3.3V) is supplied ('high' level), the reset drive unit 40 automatically operates for a predetermined time. A reset signal (Ethernet Reset Source #) is output ('low' level) to initialize the unit.

다음, 본 장치가 메인 시스템에 부착되어 동작을 수행하고 있는 도중 메인 시스템이 리셋될 경우에는 이에 동기하여 본 장치도 또한 리셋될 수 있도록 상기 메인 시스템에서 리셋 신호(Sys_Reset#)('로우'레벨)를 수신하여 '하이'레벨인 리셋 구동부(40) 자체의 리셋 신호(Ethernet Reset Source#)를 앤딩하여 리셋 신호(Ethernet Reset#)를 출력한다.Next, when the main system is reset while the device is attached to the main system and performing an operation, a reset signal Sys_Reset # ('low' level) in the main system can be reset in synchronization with the main system. Receives and resets the reset signal (Ethernet Reset Source #) of the reset driver 40 itself, which is a 'high' level, and outputs a reset signal (Ethernet Reset #).

즉, 시스템 동작 중에 본 장치를 부착할 경우는 메인 시스템에서 공급되는 전원에 의해 파워 온 리셋이 되어 바로 통신이 가능하게 되고, 시스템이 리셋될 경우도 이에 따라 같이 리셋이 되기 때문에 시스템의 동작 유무에 관계없이 언제든지 이용가능하게 된다.In other words, if the device is attached while the system is operating, it will be powered on by the power supplied from the main system, enabling communication immediately, and the system will be reset accordingly when the system is reset. It is available at any time, regardless.

이에 따라, 상기와 같이 구성된 본 장치를 메인 시스템에 부착할 경우 개발 과정에서 하드웨어 디버깅 및 프로그램 확인용으로 효율적으로 사용될 수 있으며, LAN을 구성할 경우 하나의 단말기로 각기 다른 여러개의 시스템을 독립적으로 테스트 및 디버깅이 가능하게 된다.Accordingly, when the device configured as described above is attached to the main system, it can be efficiently used for hardware debugging and program checking during the development process.In case of configuring a LAN, several different systems can be independently tested with one terminal. And debugging is possible.

이때, 본 발명에 위한 시스템의 메인 보드에는 본 장치를 부착하기 위한 커넥터가 더 추가될 뿐으로 더 이상의 단가 상승 요인은 없게 된다.At this time, the main board of the system according to the present invention merely adds a connector for attaching the apparatus, and there is no further cost increase factor.

이상에서 설명한 바와 같이 본 발명 디지털 티브이의 이더넷 장치는 시스템의 동작 여부에 관계없이 필요시에만 착탈이 가능하도록 하고, 디지털 티브이 시스템의 개발 단계에서만 요구되는 이더넷 모듈의 특성은 그대로 이용하면서 시스템의 제작 단가는 상승시키지 않는 효과가 있다.As described above, the Ethernet device of the present invention can be detached only when necessary, regardless of the operation of the system, and the production cost of the system while using the characteristics of the Ethernet module required only in the development stage of the digital TV system. Has the effect of not increasing.
