| E_MhegErr | MHEG5_Open (S_MhegConfig *pSetup) |
| Initialise MHEG5 instance. The following will be performed as a result of a call to this function: More... | |
| E_MhegErr | MHEG5_Close (void) |
| Free allocated memory region, and any other related resources. This is a synchronous blocking function. Must be called after MHEG5_Stop and normal use of the MHEG5 is completed. More... | |
| E_MhegErr | MHEG5_Start (S32BIT serviceIndex, E_ChannelStartMode *quietMode) |
| This function starts MHEG5 engine on the current broadcast service. It will cause MHEG5 engine to start retrieving the associated service information (i.e. PMT) and launch an appropriate broadcast application. This should mean MHEG5 engine will mount an associated DSM-CC carousel for this application. If this should fail, MHEG5 engine will periodically try to mount the DSM-CC boot carousel in order to launch the default MHEG-5 auto boot application. This is a non-blocking function, which may return before completion. It should be called whenever a tuning process has completed and the external application is aware of a new broadcast service. More... | |
| E_MhegErr | MHEG5_Stop (void) |
| Tells MHEG5 engine to enter stop state (i.e. no broadcast service). This function should kill any currently running MHEG5 broadcast application, and release allocated memory and resources. This is a synchronous blocking function. More... | |
| E_MhegErr | MHEG5_StopWithoutKilling (void) |
| Suspend MHEG5 engine (while there is no valid broadcast service). This function should be called as an alternative to MHEG5_Stop, in cases when the CI+ host control module requests a tune and the keep_app_running flag is set to 1. In cases when keep_app_running is set to 0, or if the implemented version of host control doesn't have the keep_app_running flag, use MHEG5_Stop. This will not kill the running MHEG application. This suspend state will remain in effect until MHEG5_Start or MHEG5_Stop is called. This is a synchronous blocking function. More... | |
| E_MhegErr | MHEG5_Suspend (void) |
| Suspend MHEG5 engine (while there is no valid broadcast service). When the external application is performing a tune as requested by MHEG5, this function should be called as an alternative to MHEG5_Stop. This may or may not kill the running MHEG application. This suspend state will remain in effect until MHEG5_Start or MHEG5_Stop is called. This is a synchronous blocking function. More... | |
| E_MhegErr | MHEG5_Reboot (void) |
| Reboots MHEG5 Engine This function has the same effect as calling these two: MHEG5_Stop( STOP_ACTION_CLEAR_DSMCC ); MHEG5_Start( current_service_dvb_locator ); Only this is a little more efficient process. This is a not synchronous blocking function. More... | |

| void | MHEG5_RestoreScreen (void) |
| Restore MHEG OSD after reset of resolution for MHEG-5 engine. More... | |
| E_MhegErr | MHEG5_SetActiveState (BOOLEAN newActiveState) |
| Set the active state for the MHEG-5 engine. When the active state is True, the MHEG-5 engine processes synchronous and asynchronous events as normal. When it is False, the MHEG-5 engine these events will be queued, but not processed. This allows the MHEG-5 component to be paused whilst another application has display focus (such as an EPG). This is a synchronous blocking function. Section 6.9 of reference [1] discusses the behaviour for pausing the MHEG-5 engine. This implementation is "Non-transparent". More... | |

MHEG5 Main task.
| E_MhegErr MHEG5_Close | ( | void | ) |
Free allocated memory region, and any other related resources. This is a synchronous blocking function. Must be called after MHEG5_Stop and normal use of the MHEG5 is completed.
Close MHEG engine. Free allocated MHEG5 engine memory region, and any other related resources. This is a synchronous blocking function. Must be called after MHEG5_Stop and normal use of MHEG5 engine has completed.
| E_MhegErr MHEG5_Open | ( | S_MhegConfig * | pSetup | ) |
Initialise MHEG5 instance. The following will be performed as a result of a call to this function:
Initialise MHEG5 engine instance. The following will be performed as a result of a call to this function:
| pSetup | Pointer configuration parameters. This defines many configuration options for MHEG5 |
| E_MhegErr MHEG5_Pause | ( | void | ) |
Pause MHEG-5 engine.
This allows MHEG5 engine to be paused whilst another application has display focus (such as an EPG). This is a synchronous blocking function. Section 16.9 of reference [1] discusses the behaviour for pausing the engine. This implementation is "Non-transparent". This may be called independently of start/stop of engine.
| None. |
| E_MhegErr MHEG5_Reboot | ( | void | ) |
Reboots MHEG5 Engine This function has the same effect as calling these two: MHEG5_Stop( STOP_ACTION_CLEAR_DSMCC ); MHEG5_Start( current_service_dvb_locator ); Only this is a little more efficient process. This is a not synchronous blocking function.

| void MHEG5_RestoreScreen | ( | void | ) |
Restore MHEG OSD after reset of resolution for MHEG-5 engine.
Refresh screen after resolution change with MHEG5_SetScreenResolution() This is a non-blocking function.
| None. |
| E_MhegErr MHEG5_Resume | ( | void | ) |
Resume MHEG-5 engine.
This allows Voyageer to be resumed after another application has had display focus (such as an EPG). This is a synchronous blocking function. Section 16.9 of reference [1] discusses the behaviour for pausing the engine. This implementation is "Non-transparent". This may be called independently of start/stop of engine.
| None. |
| E_MhegErr MHEG5_SetActiveState | ( | BOOLEAN | newActiveState | ) |
Set the active state for the MHEG-5 engine. When the active state is True, the MHEG-5 engine processes synchronous and asynchronous events as normal. When it is False, the MHEG-5 engine these events will be queued, but not processed. This allows the MHEG-5 component to be paused whilst another application has display focus (such as an EPG). This is a synchronous blocking function. Section 6.9 of reference [1] discusses the behaviour for pausing the MHEG-5 engine. This implementation is "Non-transparent".

| E_MhegErr MHEG5_SetScreenResolution | ( | U16BIT | screenWidth, |
| U16BIT | screenHeight | ||
| ) |
Reset OSD resolution for MHEG-5 engine.
Sets the screen resolution to new size. This function is required when the external application wishes to change the screen resolution. This is a synchronous blocking function. It will return when MHEG5 engine has finished using the previous resolution. After returning from this function, MHEG5 engine will NOT refresh the OSD or AV until MHEG5_RestoreScreen() is called.
| None. |
| E_MhegErr MHEG5_Start | ( | S32BIT | serviceIndex, |
| E_ChannelStartMode * | quietMode | ||
| ) |
This function starts MHEG5 engine on the current broadcast service. It will cause MHEG5 engine to start retrieving the associated service information (i.e. PMT) and launch an appropriate broadcast application. This should mean MHEG5 engine will mount an associated DSM-CC carousel for this application. If this should fail, MHEG5 engine will periodically try to mount the DSM-CC boot carousel in order to launch the default MHEG-5 auto boot application. This is a non-blocking function, which may return before completion. It should be called whenever a tuning process has completed and the external application is aware of a new broadcast service.
| serviceIndex | "Service Index" for the new service |
| quietMode | pointer to return channel change mode that MHEG5 requires of the external application. Can be NULL, if not interested in mode. |
| E_MhegErr MHEG5_Stop | ( | void | ) |
Tells MHEG5 engine to enter stop state (i.e. no broadcast service). This function should kill any currently running MHEG5 broadcast application, and release allocated memory and resources. This is a synchronous blocking function.
| E_MhegErr MHEG5_StopWithoutKilling | ( | void | ) |
Suspend MHEG5 engine (while there is no valid broadcast service). This function should be called as an alternative to MHEG5_Stop, in cases when the CI+ host control module requests a tune and the keep_app_running flag is set to 1. In cases when keep_app_running is set to 0, or if the implemented version of host control doesn't have the keep_app_running flag, use MHEG5_Stop. This will not kill the running MHEG application. This suspend state will remain in effect until MHEG5_Start or MHEG5_Stop is called. This is a synchronous blocking function.
| E_MhegErr MHEG5_Suspend | ( | void | ) |
Suspend MHEG5 engine (while there is no valid broadcast service). When the external application is performing a tune as requested by MHEG5, this function should be called as an alternative to MHEG5_Stop. This may or may not kill the running MHEG application. This suspend state will remain in effect until MHEG5_Start or MHEG5_Stop is called. This is a synchronous blocking function.
