Functions
void	HBBTV_ProcessAitSection (U16BIT ait_pid, U16BIT service_id, U8BIT *data, U32BIT nbytes)
	Requests the HbbTV engine to process the specified AIT. The HbbTV engine expects the relevant AITs only (the first one after HBBTV_Start, when the version/PID changes). If more than one stream is signalled in the PMT for a service with an application_signalling_descriptor, then the application_signalling_descriptor for the stream containing the AIT for the HbbTV application shall include the HbbTV application_type (0x0010). More...

void	HBBTV_NotifyServiceListChange (void)
	Notifies the HbbTV ending that it must update Service list. This will cause the engine to subsequently call HBBTV_ObtainServiceList().

void	HBBTV_NotifyParentalRatingChange (BOOLEAN blocked)
	Notifies the HbbTV engine that the parental rating of the currently playing service has changed. More...

void	HBBTV_NotifyChannelChangeStatus (U16BIT onet_id, U16BIT trans_id, U16BIT serv_id, E_HBBTV_CHANNEL_CHANGE_STATUS status)
	Notifies the HbbTV engine of a change in the status of the service identified by the specified DVB triplet. More...

void	HBBTV_NotifyStreamsChange (U16BIT onet_id, U16BIT trans_id, U16BIT serv_id, E_HBBTV_COMPONENT_TYPE component_type)
	Notifies the HbbTV engine of a possible change in streams for the service identified by specified DVB triplet. More...

void	HBBTV_NotifyProgrammeChanged (void)
	Notifies the HbbTV engine that the present/following events have changed on the current service.

void	HBBTV_NotifyRecordingEvent (U32BIT id, E_HBBTV_RECORDING_EVENT event)
	Notifies the HbbTV engine of a recording event. More...

void	HBBTV_NotifyPlaySpeedChanged (S16BIT speed)
	Notify the video broadcast object that the timeshift play speed has changed. More...

Function Documentation

void HBBTV_NotifyChannelChangeStatus	(	U16BIT	onet_id,
		U16BIT	trans_id,
		U16BIT	serv_id,
		E_HBBTV_CHANNEL_CHANGE_STATUS	status
	)

Notifies the HbbTV engine of a change in the status of the service identified by the specified DVB triplet.

Parameters

onet_id	Original Network ID
trans_id	Transport Stream ID
serv_id	Service ID
status	New status

void HBBTV_NotifyParentalRatingChange ( BOOLEAN blocked )

Notifies the HbbTV engine that the parental rating of the currently playing service has changed.

Parameters

blocked TRUE if the current service is blocked by the parental control system.

void HBBTV_NotifyPlaySpeedChanged ( S16BIT speed )

Notify the video broadcast object that the timeshift play speed has changed.

Parameters

speed speed represented as a signed percentage value, with 100 as normal speed

void HBBTV_NotifyRecordingEvent	(	U32BIT	id,
		E_HBBTV_RECORDING_EVENT	event
	)

Notifies the HbbTV engine of a recording event.

Parameters

id	scheduled or completed recording ID
event	recording event

void HBBTV_NotifyStreamsChange	(	U16BIT	onet_id,
		U16BIT	trans_id,
		U16BIT	serv_id,
		E_HBBTV_COMPONENT_TYPE	component_type
	)

Notifies the HbbTV engine of a possible change in streams for the service identified by specified DVB triplet.

Parameters

onet_id	Original Network ID
trans_id	Transport Stream ID
serv_id	Service ID
component_type	The type of component whose presentation has changed

void HBBTV_ProcessAitSection	(	U16BIT	ait_pid,
		U16BIT	service_id,
		U8BIT *	data,
		U32BIT	nbytes
	)

Requests the HbbTV engine to process the specified AIT. The HbbTV engine expects the relevant AITs only (the first one after HBBTV_Start, when the version/PID changes). If more than one stream is signalled in the PMT for a service with an application_signalling_descriptor, then the application_signalling_descriptor for the stream containing the AIT for the HbbTV application shall include the HbbTV application_type (0x0010).

Parameters

ait_pid	PID of the AIT
service_id	Service ID the AIT refers to
data	pointer to the buffer containing the AIT row data. It can be released as soon as the function returns.
nbytes	number of bytes contained in data
