FrontEnd 실제로 데이터를 받아들이는 부분 XDS 데이터는 VBI 데이터 안에 포함되어 있기 때문에 NTSC Decoder 드라이버 모듈에서 VBI 데이터를 추출 및 분석하여 XDS 데이터만을 뽑아내게 된다. 이 코드는 NTSC CC 코드 에 같이 포함되어 있는 경우가 많으며, 그럴 경우 CC 모듈의 VBI 처리 모듈이 FrontEnd가 된다. CC 정보가 아닌 XDS 데이터인 경우에만 BackEnd로 넘겨주면 된다. FrontEnd가 DTV Module 이 아닌 외부 장치에 있을 수도 있는데 (예: TV Host) 그럴 경우에는 TV Host가 FrontEnd 이며, 통신 Interface를 통해서 DTV Module BackEnd로 데이터가 넘겨진다. 이때 넘겨지는 데이터의 형식은 각 Host 규격에 따라 달라질 수 있다. BackEnd FrontEnd 부분에서 받은 XDS raw data (또는 일부 parsing 된 데이터)를 분석하고 이를 DB 화 하여 저장한다. Interface 1. FrontEnd - BackEnd Interface - VBI Raw 데이터를 BackEnd 에 넘겨주는 인터페이스 Raw 데이터의 형식은 아직 미정.. OnReceiveXDS... - 외부 NTSC Decoder 장치 (예: TV Host)가 수신한 XDS 데이터를 어느정도 정리하여 넘겨주는 인터페이스 DMW_XDS_UpdateXdsXXX API 2. Application Control Interface - XDS DB control DB 초기화, 저장 등.. - RF change notification FrontEnd에서 Raw XDS packet을 넘겨줄 경우라면 현재 어느 RF 에서 수신 중인지 BackEnd가 알고 있어야만 DB 구성을 할 수 있음. - XDS time setting?? 3. Application Query Interface - DB 로 저장된 XDS 데이터 중에서 Application 에서 EPG 용도로 사용할 데이터를 query 하는 API DMW_XDS_GetXXXXInfo DMW_XDS_FreeXXXInfo.. 4. Application Notification Interface - 이 모듈 내부에서 발생되는 여러가지 정보를 Application에게 알려주는 notification callback #endif //=========================================================================== // // Configuration parameters // // 각종 옵션 기능의 On/Off 설정, 컴파일러 옵션 설정, // 드라이버 관련 환경 설정 등.. // //=========================================================================== // // Constants, Variables, Function declarations // XdsChannelInfo *g_XdsChannel; enum { XDS_EVENT_CH_DB_UPDATED = 1000, // // XDS data가 수신되어서 Channel DB (주로 CSD) 항목이 변경되었음. // NvRam 에 DB update를 해야 할 필요가 있다. // // param : none // XDS_EVENT_EPG_DB_UPDATED, // // XDS data가 수신되어서 Program DB 항목이 변경되었음. }; typedef STATUS (*XdsEventCallback)(int event, UINT32 param); // // user callback function pointer // user에게 알려줄 정보가 있으면 이 callback을 통해서 알려준다. // XdsEventCallback g_fnXdsEventCallback; //=========================================================================== // // Implementations // #if COMMENT ____Mutex______(){} #endif // Mutex = { SemID, Owner, lockCnt, FailCnt, UseOsMutex, Name, flag, traceLvl } // DMW_MUTEX g_MutexXdsInfo = { 0, 0, 0, 0, FALSE, "XdsInfo", OS_SEM_PRIO, FALSE, }; void LockXdsInfoMutex(BOOL bLock) { if (bLock) DMW_LockMutex(&g_MutexXdsInfo); else DMW_UnlockMutex(&g_MutexXdsInfo); } void DeleteXdsInfoMutex() { DMW_DeleteMutex(&g_MutexXdsInfo); } #if COMMENT ____XdsInfo_______(){} #endif //------------------------------------------ // FindXdsChannelInfoByRf // // rf 에 해당하는 Channel Info를 찾아서 포인터를 리턴. // 없으면 NULL을 리턴한다. // // Unlock 상태에서 작업하기 때문에 caller가 Lock을 해야 한다. // XdsChannelInfo *FindXdsChannelInfoByRf(int rf) { XdsChannelInfo *chInfo = g_XdsChannel; while (chInfo) { if (chInfo->rf == rf) return chInfo; chInfo = chInfo->pNext; } return NULL; } //------------------------------------------ // AllocateNewXdsChannelInfo // // 새롭게 XdsChannelInfo 메모리를 할당하고, DB에 추가한 후에 // 포인터를 리턴한다. // 지정한 rf의 channel info는 기존 DB에 없어야 한다.
