void | ClearTexIdAccounts (S_DsmResource **ppDsmRes) |
BOOLEAN | SFMFilterCreateResources (H_SfmInstance sfm) |
Create Filter resources for Section Filter Manager instance. More... | |
void | SFMFilterInitCaching (H_SfmInstance sfm) |
Initialise caching references. More... | |
void | SFMFilterDestroyResources (H_SfmInstance sfm) |
Destroy Filter resources for Section Filter Manager instance. More... | |
void * | SFM_DsmccFilterAdd (H_SfmInstance sfm, P_SecFilter pFilter, H_DscSFRef dsmSfRef) |
Add DSM-CC section filter. Called by DSM-CC component. Note for multi-tasking: this function uses mutex locking to protect shared data with SFM_RequireSection. It assumes that this function is entered on the same task as SFM_DelectionFilter. More... | |
void | SFM_DsmccFilterDelete (H_SfmInstance sfm, void *filterHandle, H_DscSFRef dsmSfRef) |
Delete DSM-CC section filter. Called by DSM-CC component, and given in clDsmSysCreate setup. Note for multi-tasking: this function uses mutex locking to protect shared data with SFM_RequireSection. More... | |
void | SFM_FilterUpdate (H_SfmInstance sfm, H_DmxPidFilter pPF) |
Update SFM PID filter to configure HW for latest requirements. More... | |
void | SFM_DsmccFilterPriorityChange (H_SfmInstance sfm, void *filterHandle, H_DscSFRef dsmSfRef, E_SFPriority priority) |
Change DSM-CC section filter priority Called by DSM-CC component, and given in clDsmSysCreate setup. Note for multi-tasking: this function uses mutex locking to protect shared data with SFM_RequireSection. This function should be in same tthread as add and remove. More... | |
E_SFM_STATUS | SFMFilterRequiresSection (H_SfmInstance sfm, PIDFILT pfid, U16BIT teid, U8BIT tid, U8BIT vers, void **phBuffer) |
This function performs minimal checking of section header data to find out whether SFM requires this section. Number of header bytes required is SECTION_HEADER_LENGTH. It assumes CRC has been checked and is passing valid DSM-CC sections So the first byte of data must be table id 0x3B, 0x3C or 0x3D. Note for multi-tasking: this function uses mutex locking to protect shared data with SFM_AddSectionFilter and SFM_DelSectionFilter. It does NOT call any DSM-CC core functions. More... | |
void | SFMFilterProcessSection (H_SfmInstance sfm, U8BIT *pSection, H_DsmResource pDsmRes) |
Get DSM-CC filter request and pass section buffer to DSM-CC with it's filter handle This should only be called after calling SFM_FilterRequiresSection with it returning SFM_UPDATE_LOW or SFM_UPDATE_HIGH. More... | |
