Parameters

@return

E_HBBTV_ERR HBBTV_ProcessAitSection	(	U16BIT	service_id,
		U8BIT *	data,
		U32BIT	nbytes
	)

Requests the HBBTV engine to process the specified AIT.

Requests the HbbTV engine to process the specified AIT. The HbbTV engine expects the relevant AITs only (the first one after HBBTV_Start and when the version 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

service_id	Service ID he AIT refers to
data	pointer to the buffer containing the AIT row data
nbytes	number of bytes contained in data

Returns

HBBTV_OK is the AIT has been parsed correctly, HBBTV_IGNORED_REQUEST if the service ID is not the current one. Other possible error codes are: HBBTV_ERR_COMP_NOT_OPEN, HBBTV_ERR_COMP_NOT_STARTED, HBBTV_ERR_SYSTEM_RESOURCE, HBBTV_ERR_BAD_PARAMETER
