Description
본 발명은 디지털 TV 방송에서 애플리케이션 및 가변 데이터를 처리하는 시스템 및 방법에 관한 것으로서, 특히 송신장치로부터 애플리케이션 어드레스 정보를 전송받고, 상기 전송받은 애플리케이션 어드레스 정보에 대한 애플리케이션을 방송국 서버에 요청하여 해당 애플리케이션을 다운로드 받는 디지털 TV 방송에서 애플리케이션 및 가변 데이터를 처리하는 시스템 및 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for processing applications and variable data in digital TV broadcasting. In particular, the present invention relates to a system and method for receiving application address information from a transmitting device, and requesting an application for the received application address information from a broadcasting station server to provide the application. The present invention relates to a system and method for processing applications and variable data in a digital TV broadcast.
일반적으로, 디지털 TV에서 애플리케이션 데이터(Application Data)를 전송하기 위한 방식은 크게 공중파에 데이터를 섞어서 보내는 방식과, 네트워크(Network)망을 이용하여 방송국 서버로부터 직접 데이터를 수신하는 방식이 사용되고 있다.In general, a method for transmitting application data in a digital TV is mainly used to mix data over the air and to receive data directly from a broadcasting station server using a network.
먼저, 공중파를 이용하여 애플리케이션 데이터를 전송하는 방식은 DSMCC-CC 데이터 캐루셀(Data Carousel)로 명명되며, 상기 데이터 캐루셀을 적용한 방식은 애플리케이션을 구성하는 데이터를 반복적으로 전송함으로써, 사용자가 임의 시간에 애플리케이션을 실행시키더라도 대응할 수 있다. 일반적으로, 실제 필요한 데이터는 애플리케이션이 시작될 때에만 집중되기 때문에, 애플리케이션이 시작되고 난 후에는 변화된 데이터만 전송하면 효율적이다. 그러나, 데이터 캐루셀을 적용하는 방식은 변화하는 데이터 뿐만 아니라 초기 애플리케이션을 실행시키기 위한 데이터도 반복적으로 전송되므로 데이터를 전송하는데 지연이 발생하는 문제점이 있다. 특히, 오디오/비디오 데이터와 함께 애플리케이션을 실행시키기 위한 데이터를 전송할 경우 많은 데이터를 전송하기 위해 시간적으로 지연되는 현상이 나타나며, 또한 데이터를 반복 전송 함으로써 큰 대역폭을 이용해야 하는 문제점이 있다.First, a method of transmitting application data using airwaves is called a DSMCC-CC data carousel, and the method of applying the data carousel repeatedly transmits data constituting an application, thereby allowing a user to randomly You can also respond to running the application. In general, the actual required data is concentrated only when the application is started, so it is efficient to send only the changed data after the application is started. However, the method of applying the data carousel has a problem in that a delay occurs in transmitting data since not only changing data but also data for executing an initial application are repeatedly transmitted. In particular, when transmitting data for executing an application together with audio / video data, a time delay occurs to transmit a large amount of data, and there is a problem that a large bandwidth is used by repeatedly transmitting the data.
네트워크를 통해서 데이터를 받는 방식은, ATSC와 같은 데이터 방송 규격에서 제안하고 있는 방식이다. 즉, 공중파를 통해 애플리케이션 데이터가 있는 주소를 주기적으로 전송받고, 상기 전송받은 애플리케이션 데이터의 주소에 따른 애플리케이션 데이터와 변화된 가변 데이터를 서버에서 전송받는 방식이다. 그러나, 서버 입장에서 볼 때 항상 많은 시청자들이 애플리케이션 데이터를 전송받기 위해 서비스를 요구하므로 서버에 부하가 걸리게 되며, 이를 해결하기 위해 서버의 증설, 용량 및 속도 확대 등으로 인하여 많은 비용이 발생되는 문제점이 있다.The method of receiving data through a network is a method proposed by a data broadcasting standard such as ATSC. That is, a method of periodically receiving an address with application data through airwaves and receiving the application data and the changed variable data according to the address of the received application data from the server. However, from the server's point of view, many viewers require a service in order to receive application data. Therefore, a load is placed on the server. To solve this problem, a large cost is generated due to expansion of the server, capacity, and speed. have.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 송신장치로부터 애플리케이션 어드레스 정보를 전송받고, 상기 전송된 애플리케이션 어드레스 정보를 이용하여 해당 애플리케이션을 방송국 서버로부터 다운로드 받는 디지털 TV 방송에서 애플리케이션 및 가변 데이터를 처리하는 시스템 및 방법을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to receive an application address information from a transmitter and to download a corresponding application from a broadcasting station server using the transmitted application address information. It is to provide a system and method for processing applications and variable data.
본 발명의 다른 목적은 송신장치로부터 가변 데이터를 전송받음으로써 방송국 서버의 부하를 줄일 수 있는 디지털 TV 방송에서 애플리케이션 및 가변 데이터를 처리하는 시스템 및 방법을 제공하는 것이다.Another object of the present invention is to provide a system and method for processing applications and variable data in digital TV broadcasting, which can reduce the load of a broadcasting station server by receiving variable data from a transmitting device.

애플리케이션 요청부(230)는 상기 추출부(220)에서 추출한 애플리케이션 어드레스 정보를 이용하여 방송국 서버(300)에 접속하고, 상기 방송국 서버(300)에 애플리케이션을 요청한다.The application requesting unit 230 accesses the broadcasting station server 300 using the application address information extracted by the extracting unit 220 and requests an application from the broadcasting station server 300.
애플리케이션 처리부(240)는 상기 애플리케이션 요청부(230)가 방송국 서버(300)에 요청한 애플리케이션을 방송국 서버(300)로부터 전송받아 다운로드한다.The application processor 240 receives and downloads an application requested by the application requesting unit 230 from the broadcasting station server 300.
방송국 서버(300)는 상기 애플리케이션 요청부(230)에서 요청한 애플리케이션을 검색하여 해당 애플리케이션을 애플리케이션 처리부(240)로 전송한다. 여기서, 상기 애플리케이션 처리부(240)로 전송하는 애플리케이션은 애플리케이션을 시작할 때 필요한 데이터를 말한다. 한편, 방송국 서버(300)는 상기 수신장치(200)와 네트워크로 연결되어 있으며, 항상 최신 버젼의 애플리케이션을 보유한다. 또한, 방송국 서버(300)는 가변된 데이터를 송신장치(100)에 전송한다.The broadcasting station server 300 searches for an application requested by the application requesting unit 230 and transmits the corresponding application to the application processing unit 240. Here, the application transmitted to the application processor 240 refers to data required for starting the application. On the other hand, the broadcasting station server 300 is connected to the receiving apparatus 200 by the network, and always has the latest version of the application. In addition, the broadcasting station server 300 transmits the variable data to the transmitter 100.
도 3은 본 발명에 따른 디지털 TV 방송에서 애플리케이션 및 가변 데이터를 처리하는 방법을 개략적으로 나타낸 플로우챠트로서, 먼저 송신장치(100)에서 전송한 방송 데이터를 수신부(210)가 수신하여 추출부(220)로 전송하면, 상기 추출부(220)는 상기 전송받은 방송 데이터에서 애플리케이션 어드레스 정보를 추출한다(S100).3 is a flowchart schematically illustrating a method of processing an application and variable data in a digital TV broadcast according to the present invention. First, the receiver 210 receives the broadcast data transmitted from the transmitter 100 to extract the receiver 220. In step S100, the extractor 220 extracts application address information from the received broadcast data.
그 다음, 애플리케이션 요청부(230)가 상기 추출부(220)에서 추출한 애플리케이션 어드레스 정보를 이용하여 방송국 서버(300)에 접속하고, 상기 방송국 서버(300)에 해당 애플리케이션을 요청한다(S110).Next, the application requesting unit 230 accesses the broadcasting station server 300 by using the application address information extracted by the extracting unit 220, and requests the corresponding application from the broadcasting station server 300 (S110).
그러면, 상기 방송국 서버(300)는 요청받은 애플리케이션(즉, 애플리케이션 시작시 필요한 데이터)을 검색하여 애플리케이션 처리부(240)로 전송해 준다(S120). 여기서, 방송국 서버(300)에서 수신장치(200)로 전송하는 애플리케이션은 항상 최신 버젼이다.Then, the broadcasting station server 300 searches for the requested application (ie, data required for starting the application) and transmits it to the application processor 240 (S120). Here, the application transmitted from the broadcasting station server 300 to the receiving device 200 is always the latest version.
이 후, 상기 애플리케이션 처리부(240)는 방송국 서버(300)로부터 전송된 애플리케이션을 다운로드한다(S130). 여기서, 애플리케이션 시작시 필요한 데이터가 다운로드 됨으로써, 더이상 애플리케이션 시작에 필요한 데이터는 다운로드 받을 필요가 없으며, 이 후 필요에 따라 가변되는 데이터들만을 다운로드 받으면 된다.Thereafter, the application processor 240 downloads the application transmitted from the broadcasting station server 300 (S130). In this case, since the data required for starting the application is downloaded, the data necessary for starting the application does not need to be downloaded any longer, and only data that is variable according to need is then downloaded.
한편, 방송국 서버(300)로부터 가변 데이터를 전송 받으면 송신장치(100)는 상기 방송국 서버(300)로부터 전송된 가변된 데이터를 수신장치(200)로 전송한다. 이에, 수신부(210)는 상기 전송된 가변 데이터를 수신하고(S140), 애플리케이션 처리부(240)는 상기 수신된 가변된 데이터를 다운로드 하여 실행중인 애플리케이션을 업데이트 한다(S150). 여기서, 상기 다운로드된 가변 데이터는 현재 실행중인 애플리케이션에 바로 적용될 수도 있고, 애플리케이션의 재 실행시 적용될 수도 있다.On the other hand, when receiving the variable data from the broadcast station server 300, the transmitter 100 transmits the variable data transmitted from the broadcast station server 300 to the receiver 200. Accordingly, the receiver 210 receives the transmitted variable data (S140), and the application processor 240 updates the running application by downloading the received variable data (S150). Here, the downloaded variable data may be directly applied to the currently running application or may be applied when the application is executed again.
도 4는 본 발명에 따른 방송국 서버에서 가변 데이터에 따른 애플리케이션 버젼을 업데이트하는 실시예를 나타낸 도면이다. 예를 들어, 방송국 서버(300)가 애플리케이션 버젼 1을 가지고 있다고 가정한다.4 is a diagram illustrating an embodiment of updating an application version according to variable data in a broadcasting station server according to the present invention. For example, assume that broadcast station server 300 has application version 1.
방송국 서버(300)는 일정 시간을 기준으로 가변된 데이터의 존재 유무를 체크하며, 애플리케이션 버젼 2와 같이 새롭게 추가된 파일(예를 들어, c'txt, d'txt, f'dat 및 h'png 등)이 존재할 경우 해당 애플리케이션 버젼(예를 들어, 애플리케이션 버젼 2)으로 업데이트(update)한다. 이 후, 가변된 데이터들을 송신장치(100)로 전송한다.The broadcasting station server 300 checks the presence or absence of variable data based on a predetermined time, and newly added files (for example, c'txt, d'txt, f'dat, and h'png) as in application version 2. Etc.), if there is one, update to the corresponding application version (for example, application version 2). Thereafter, the changed data is transmitted to the transmitter 100.
또한, 일정 시간 경과 후 애플리케이션 버젼 3과 같이 새로 추가된 가변 데이터들이 체크되면 방송국 서버(300)는 새롭게 추가된 파일(예를 들어, c''txt, d''txt, f''dat, h''png 및 i'png 등)의 애플리케이션 버젼으로 업데이트 한다.즉, 상기 방송국 서버(300)는 일정 시간을 기준으로 애플리케이션 버젼을 체크하여 새롭게 추가된 가변 데이터들이 존재하면 새로운 애플리케이션 버젼으로 업데이트를 수행하고, 가변된 데이터들을 송신장치(100)로 전송한다.In addition, if the newly added variable data, such as the application version 3 is checked after a certain period of time, the broadcast station server 300 is a newly added file (for example, c''txt, d''txt, f''dat, h `` png and i'png), etc.). That is, the broadcasting station server 300 checks the application version based on a predetermined time, and if there are newly added variable data, updates to the new application version. Then, the variable data is transmitted to the transmitter 100.
이상에서 본 발명에 대하여 상세히 기술하였지만, 본 발명이 속하는 기술 분야에 있어서 통상의 지식을 가진 사람이라면, 첨부된 청구범위에 정의된 본 발명의 정신 및 범위를 벗어나지 않으면서 본 발명을 여러 가지로 변형 또는 변경하여 실시할 수 있음은 자명하며, 따라서 본 발명의 실시예에 따른 단순한 변경은 본 발명의 기술을 벗어날 수 없을 것이다.Although the present invention has been described in detail above, those skilled in the art to which the present invention pertains may variously modify the present invention without departing from the spirit and scope of the present invention as defined in the appended claims. It is apparent that the present invention may be modified or modified. Therefore, a simple change according to an embodiment of the present invention will not be possible without departing from the technology of the present invention.
상기한 구성의 본 발명에 의하면, 송신장치로부터 전송된 애플리케이션 어드레스 정보를 수신한 후 해당 애플리케이션을 방송국 서버에서 전송받음으로써 네트워크를 통해 빠르게 애플리케이션을 전송받을 수 있는 잇점이 있다.According to the present invention having the above-described configuration, there is an advantage that the application can be quickly transmitted through the network by receiving the application address information transmitted from the transmitting apparatus and then receiving the corresponding application from the broadcasting station server.
또한, 시청자가 애플리케이션 시작시에만 방송국 서버에 애플리케이션을 요청하므로 방송국 서버의 네트워크 부하를 줄일 수 있고, 네트워크의 대역폭을 절약할 수 있는 잇점이 있다.In addition, since the viewer requests the application to the broadcasting station server only at the start of the application, the network load of the broadcasting station server can be reduced, and the bandwidth of the network can be saved.
또한, 송신장치를 통해 가변된 데이터만을 전송받을 수 있기 때문에 대역폭을 절약할 수 있는 잇점이 있다.In addition, since only variable data can be transmitted through the transmitter, there is an advantage of saving bandwidth.
