본 발명은 디지털 방송 수신 장치에 관한 것으로, 특히 방송 채널의 스위칭을 위한 채널 맵을 생성하는 방법 및 디지털 방송 수신 장치에 관한 것이다. The present invention relates to a method of generating a channel map for a, more particularly, the switching of a broadcast channel in digital broadcast receiver and digital broadcast receiver.

통상적으로 위성 디지털 멀티미디어 방송(Digital Multimedia Broadcasting : 이하 DMB)의 전송 규격으로 MPEG(Motion Picture Experts Group)-2 TS(Transport Stream)를 사용한다. Typically a satellite digital multimedia broadcasting (DMB): Use (Motion Picture Experts Group) -2 TS (Transport Stream) to the MPEG transmission standard of (Digital Multimedia Broadcasting hereinafter DMB). 이러한 DMB 방송 규격에 따르면 DMB 방송 채널은 Walsh code 정보를 포함하는 CDM(Code Division Multiplex) 채널의 구성 정보를 전송하는 Pilot 채널과, DMB 방송의 수신에 대한 인증 정보를 전송하는 CAS( Conditional Access System) 채널, 서비스 채널에 대한 정보를 전송하는 EPG(Electronic Program Guide) 채널, 그리고 실제 전송 스트림(Transport Packet:이하 TS라 칭한다) 패킷 데이터를 전송하는 적어도 하나의 미디어 채널로 구성된다. This according to the DMB broadcasting standard DMB broadcast channel (Conditional Access System) CAS sending authentication information for the reception of, DMB broadcast with the Pilot channel for transmitting configuration information of (Code Division Multiplex) CDM channel including Walsh code information, (Electronic Program Guide) for transmitting EPG information about the channel, the channel service channel, and the actual transport stream (transport packet: hereinafter referred to as TS) consists of at least one media channel for transmitting packet data.

디지털 방송 센터는 PSI(Program Specific Information) 정보를 디지털 방송 수신 장치로 전송하며, 방송 수신 장치는 PSI(Program Specific Information) 정보을 참조하여 사용자가 선택한 채널에 따른 TS 데이터를 수신할 수 있다. Digital broadcast center sends the (Program Specific Information) PSI information to the digital broadcast receiver, the broadcast receiver may receive a TS data according to the channel selected by the user with reference jeongboeul (Program Specific Information) PSI. 여기에서, PSI 정보로는 SDT(Service Description Table), PAT(Program Association Table), PMT(Program Map Table)가 있다. Here, a PSI information has SDT (Service Description Table), PAT (Program Association Table), PMT (Program Map Table). SDT는 현재 방송되고 있는 방송 서비스 채널들 및 관련 정보를 포함하며, 사용자는 이 SDT를 참조하여 원하는 채널을 선택할 수 있다. SDT includes a broadcast service channels currently being broadcast and related information, and the user can select the channel you want to see the SDT. PAT는 현재 방송 중인 방송 채널 ID(identification)와 그 방송 채널의 추가 정보를 갖고 있는 PMT의 PID(Packet Identification)를 포함한다. The PAT includes the PID (Packet Identification) of the PMT having additional information of a broadcast channel ID (identification) and the broadcast channel currently being broadcast. 그리고 PMT는 개별 방송 채널에 해당하는 비디오 및 오디오 TS의 PIDs를 포함한다. And PMT contains PIDs of video and audio TS corresponding to an individual broadcasting channel.

즉, 디지털 방송 수신 장치는 소정 방송 채널의 디지털 멀티미디어 방송을 출력하기 위해서는 그 채널의 TS 패킷 데이터들의 PID(이하 Packet Elementary Stream Packet Identification: PES PID라 칭하기로 한다)값을 알아야 한다. That is, the digital broadcast receiver is the PID of the TS packet data channel in order to output the digital multimedia broadcast of the predetermined broadcast channel: It should be noted (the Elementary Stream Packet Identification is a PES Packet PID referred la) value. 이 PES PID는 SDT로부터 사용자가 선택한 채널의 채널 ID를 상기 PAT와 PMT에서 검색함으로써 알 수 있다. A PES PID may be found by searching for the channel ID of the channel selected by the user from the SDT in the PAT and PMT.

그러므로 디지털 방송 수신 장치는 사용자가 선택한 채널에 따른 PES PID를 가진 TS 패킷 데이터만을 수신함으로써 사용자에게 사용자가 선택한 채널의 디지털 멀티미디어 방송 서비스를 제공할 수 있다. Therefore, the digital broadcast receiver may provide the user and the TS packet only the digital multimedia broadcast of the user-selected channel service to the user by receiving data with the PES PID according to the channel selected. 이를 위해 디지털 방송 수신 장치는 디지털 방송 수신 센터로부터 방송되는 TS 패킷 데이터들 중에서 사용자가 선택한 채널의 PES PID를 가진 TS 패킷들만을 필터링할 수 있어야 하는데 이를 위해 사용되는 것이 바로 Walsh code다. To this end, the digital broadcasting reception device is directly Walsh code to be used for this purpose must be able to filter only the TS packet having a PES PID of the channel selected by the user from among the TS packet data broadcasted from the digital broadcasting reception center.

여기서 Walsh Code는 일종의 직교(Orthogonal) 코드의 집합을 의미하는 것으로서 지상파 DMB의 전송 규격인 MPEG-2에서는 특정 채널의 TS 패킷 데이터만을 필터링하기 위해 사용되는 것이다. The Walsh Code is in the MPEG-2 transport standard of the terrestrial DMB as meaning a sort of set of orthogonal (Orthogonal) code is used in order to filter only the TS packet data of a particular channel. 이러한 Walsh Code에 대한 정보는 상술한 바와 같은 DMB 전송 규격의 5개 채널 중 Pilot 채널을 통해 전송된다. Information on such Walsh Code is transmitted through the Pilot channel of the five channels of the DMB transmission standard as described above. 디지털 방송 수신 장치는 Pilot 채널로부터 각각의 CDM(Code Division Multiplex) 채널들에 대한 최대 PID 값의 범위와 최소 PID 값의 범위에 대한 정보를 수신한다. Digital broadcast receiving apparatus receives information about a range of the maximum value and the minimum PID range of the PID value for each of the (Code Division Multiplex) CDM channel from the Pilot channel. 따라서 디지털 방송 수신 장치는 사용자가 어느 하나의 채널을 선택하는 경우 해당 채널에 대한 Walsh code 값을 베이스밴드 처리부에 설정하고, 설정된 Walsh code의 최대 최소 PID 범위 안에 해당되는 PES PID를 가진 TS 패킷만을 필터링하여 수신한다. Therefore, the digital broadcast receiver by the user either case of selecting one channel set Walsh code value for the selected channel to the baseband processing section, and filtering only TS packets having a PES PID corresponding in maximum and minimum PID range of the set Walsh code the received.

즉, 디지털 방송 수신 장치는 사용자가 선택한 채널에 해당되는 TS 패킷 데이터들을 수신하기 위해 사용자가 선택한 채널에 따른 PMT PID 및 PES PID에 해당되는 Walsh Code를 검색하고 베이스밴드 처리부에서 검색한 Walsh Code를 설정하는 과정을 거쳐야만 한다. That is, the digital broadcast receiver sets a Walsh Code users to search and retrieve from the baseband processor to Walsh Code that corresponds to the PMT PID, and PES PID according to the channel selected to receive the TS packet data to which users are available for the selected channel It must undergo the process.

이와 같이, 통상적인 디지털 방송 수신 장치에서는 사용자가 채널을 변경할 때마다 PAT 및 PMT를 분석하여 Walsh Code 설정 과정을 거쳐야만 했으므로 사용자가 선택한 채널의 TS 패킷 데이터를 수신하기 위해 소요되는 시간이 길어지게 된다는 문제점이 있었다. Thus, the conventional digital broadcast receiver, the user each time when changing the channel analysis to the PAT and the PMT and because until after Walsh Code setup problem that becomes the longer time it takes to receive the TS packet data of a channel selected by the user there was.

그러므로 본 발명는 디지털 방송 수신 장치에서 사용자가 방송 채널을 전환하는 경우 사용자가 선택한 방송 채널의 TS 패킷 데이터를 수신하기 위해 소요되는 시간을 감소시킬 수 있도록 방송 채널의 스위칭을 위한 채널 맵을 생성하는 방법 및 이를 위한 디지털 방송 수신 장치를 제공한다. Therefore, how to generate the balmyeongneun digital broadcast receiver the channel map for the switching of a broadcast channel so that the user can reduce the time it takes to receive the TS packet data of the selected broadcast channel if the user switches on a broadcast channel from and It provides a digital broadcasting receiver therefor.

상술한 목적을 달성하기 위한 본 발명의 실시 예에 따른 디지털 방송 수신 장치에서 채널 맵을 생성하는 방법은 디지털 방송 수신 장치에서 채널 맵을 생성하는 방법에 있어서, 상기 디지털 방송 수신 장치의 충전이 개시되는 지를 판단하는 단계와, 상기 디지털 방송 수신 장치의 충전이 개시되면 복수개의 방송 서비스 채널에 대해 PMT PID, PES PID 및 Walsh code를 서치하여 데이터베이스화함으로써 채널 맵을 생성하는 단계를 포함한다. Method of generating a channel map from a digital broadcast receiver according to an embodiment of the present invention for achieving the above object is a method for generating a channel map from a digital broadcast receiver, that is the charge of the digital broadcast receiving apparatus disclosed After this step, a charge of the digital broadcast receiving apparatus determines whether to initiate the broadcast service for the plurality of channel search the PMT PID, PES PID, and Walsh code comprises the step of generating a channel map by a database.

본 발명의 실시예에 따라 디지털 방송 수신 장치는 사용자가 디지털 방송 수신하지 않는 소정 기간인 충전 기간에 복수개의 방송 서비스 채널에 대해 PMT PID, PES PID 및 Walsh code를 서치하여 데이터베이스화함으로써 채널 맵을 생성한다. In accordance with an embodiment of the present invention, a digital broadcast receiver generates a channel map by screen user to search the PMT PID, PES PID and a Walsh code for a plurality of broadcast service channels in the charging period predetermined period of time does not receive digital broadcast database do. 여기에서, 디지털 방송 수신 장치는 충전 기간에 고정 전원에 연결되어 있기 때문에 배터리의 전력을 소모하지 않으면서 채널 맵을 생성할 수 있다. Here, the digital broadcasting receiver may generate a channel map standing unless consumption of battery power, because it is connected to the fixed power to a charge period. . . PES PID는 비디오 ID 및 오디오 ID를 포함한다. The PES PID comprises a video ID and audio ID.

그리고 사용자가 디지털 방송 수신하지 않는 소정 기간은 디지털 방송 수신 장치가 충전되는 기간에 한정되지 않는다. And the predetermined period of time the user does not receive the digital broadcasting is not limited to the period in which the digital broadcast receiver charging.

이러한 본 발명의 실시예에 따른 디지털 방송 수신 장치의 블록 구성도를 도 1을 참조하여 설명한다. A block diagram of a digital broadcasting receiver according to this embodiment of the invention will be described with reference to FIG.

도 1은 본 발명의 실시예에 따른 디지털 방송 수신 장치의 블록 구성도이다. 1 is a block diagram of a digital broadcasting receiver according to an embodiment of the present invention.

도 1을 참조하면 디지털 방송 수신 장치(100)는 베이스밴드 처리부(110), PSI 파싱부(120), Walsh code 설정부(130), 메모리(140) 및 채널 설정 제어부(150)를 포함한다. Referring to Figure 1 a digital broadcast receiver 100 comprises a baseband processing section (110), PSI parsing unit (120), Walsh code setting unit 130, a memory 140, and a channel setting controller 150. 채널 설정 제어부(150)는 사용자가 소정 방송 채널을 선택하면 그 채널에 대한 TS 패킷 데이터를 수신하도록 베이스밴드 처리부(110)를 제어한다. Channel setting control unit 150 controls the baseband processing unit 110 when a user selects a desired broadcast channel to receive the TS packet data for the channel. 또한, 채널 설정 제어부(150)는 사용자가 디지털 방송 수신하지 않는 소정 기간에 복수개의 방송 서비스 채널에 대해 PMT PID, PES PID 및 Walsh code를 서치하여 데이터베이스화한다. In addition, the channel setting, the controller 150 searches a database to the user and the PMT PID, PES PID and a Walsh code for a plurality of broadcast service channel in a predetermined period of time does not receive digital broadcasting. 다시 말해 채널 설정 제어부(150)는 사용자가 디지털 방송 수신하지 않는 소정 기간에 베이스밴드 처리부(110)를 통해 Pilot 채널, EPG 채널, CAS 채널 및 적어도 하나의 미디어 채널을 수신하도록 한다. In other words, the channel set, the controller 150 allows the user to receive the Pilot channel, EPG channel, CAS channel and at least one media channel via the baseband processor 110 in a predetermined period of time does not receive digital broadcasting. 본 실시예에서, 채널 설정 제어부(150)는 충전 기간에 베이스밴드 처리부(110)를 통해 Pilot 채널, EPG 채널, CAS 채널 및 적어도 하나의 미디어 채널을 수신하도록 한다 In this embodiment, the channel setting control unit 150 to receive the Pilot channel, EPG channel, CAS channel and at least one media channel via the base band processing unit 110 to the charge period

왜냐하면 충전시에 디지털 방송 수신 장치는 고정 전원에 연결되어 있기 때문에 배터리의 전력을 소모하지 않으면서 채널 맵을 생성할 수 있다. Because digital broadcasting receiving the charging device can generate a channel map books do not consume battery power because it is connected to a fixed power source.

베이스밴드 처리부(110)는 Pilot 채널로부터 수신한 Walsh Code들에 대한 정보를 이용하여 각각의 CDM 채널들에 대한 Walsh code의 최대 PID 값과 최소 PID값을 포함하는 Walsh Code MAP을 생성하여 Walsh code 설정부(130)에 제공한다. The baseband processing section 110 Walsh code set to generate a Walsh Code MAP containing up to PID value and the minimum PID value of the Walsh code for each of the CDM channel using information on a Walsh Code received from the Pilot Channel and provides it to the unit 130. 그리고 베이스밴드 처리부(110)는 EPG 채널을 통해 SDT를 획득한다. And a baseband processing section 110 acquires the SDT through an EPG channel. 또한, 베이스밴드 처리부(110)는 CAS 채널을 통해 PAT를 획득하고, 적어도 하나의 미디어 채널을 통해 PMT를 획득한다. In addition, the baseband processing unit 110 obtains the PMT acquire PAT through a CAS channel, through the at least one media channel. 여기에서 SDT는 사용자에게 디지털 방송을 가이드하기 위한 것이므로 디지털 방송 수신시에 직접적으로 필요한 정보는 아니다. Here SDT is intended for guiding the user to digital broadcasting is not the necessary information directly at the digital broadcast reception. 그리고 전술한 바와 같이 PAT는 현재 방송 중인 방송 채널 ID(identification)와 그 방송 채널의 추가 정보를 갖고 있는 PMT의 PID(Packet Identification)를 포함한다. And as described above, the PAT includes the PID (Packet Identification) of the PMT having additional information of a broadcast channel ID (identification) and the broadcast channel currently being broadcast. 그리고 PMT는 개별 방송 채널에 해당하는 비디오 및 오디오 TS의 PIDs를 포함한다. And PMT contains PIDs of video and audio TS corresponding to an individual broadcasting channel.

이러한 PAT 및 PMT는 PSI 파싱부(120)에 입력된다. The PAT and PMT are inputted to the PSI parser 120. PSI 파싱부(120)는 PAT 및 PMT를 파싱하여 각 방송 서비스 채널에 대한 PMT PID, PES PID(Audio PID 및 Video PID)를 획득한다.

Accordingly, to obtain the digital broadcast receiver 100 in step 250 PMT PID, PES PID (Audio PID and Video PID) and a Walsh code. PMT PID는 PAT로부터 획득되며, Audio PID 및 Video PID는 PMT로부터 획득된다. PMT PID is obtained from the PAT, PID Audio and Video PID is obtained from the PMT. 그리고 PES PID에 대응한 Walsh Code 값은 Walsh code MAP로부터 획득된다. And a Walsh Code value that corresponds to a PES PID is obtained from the Walsh code MAP. 디지털 방송 수신 장치(100)는 단계 260에서 획득한 PMT PID, Video PID, Audio PID 및 Walsh code를 해당 서비스 채널에 대응하여 저장함으로써 채널 맵을 생성한다. Digital broadcast receiver 100 is a PMT PID, Video PID, Audio PID and Walsh code obtained at step 260 in response to the service channel and generates a channel map, by storing. 그리고 디지털 방송 수신 장치(100)는 충전이 종료될 때까지 단계 220 내지 단계 260을 계속적으로 수행하여 각 서비스 채널에 대한 PMT PID, Video PID, Audio PID 및 Walsh code를 획득하고 채널 맵을 생성한다. And the digital broadcast receiver 100 obtains the PMT PID, Video PID, Audio PID and a Walsh code for each service channel by performing step 220 to step 260 continuously until the charging is completed and generates a channel map.
