Function Documentation

clDsmErr_t clDsmStreamGetDeferredService	(	clDsmInstHandle_t	instance,
		clDsmObjHandle_t	streamObject,
		void *	userData1,
		void *	userData2,
		S_DvbLocator **	ppDeferredService
	)

The Client calls this function to obtain the Association Tag which can be used to determine the PID on which stream data can be found. Before calling this function the Client must have completed loading and opened the stream object.

Parameters

dsmccInstance	Allows support >= 1 instance of a DSMCC.
streamObject	This handle indicates the stream object
userData1	Optional data to be used by client. This data is stored and returned unchanged to the Client using a callback.
userData2	Optional data to be used by client. This data is stored and returned unchanged to the Client using a callback.
pDeferredService	return a pointer to deferred service structure

Returns: CLDSM_ERR_INVALID_OBJECT_HANDLE The supplied object handle was not valid. CLDSM_ERR_INVALID_OBJECT_TYPE The streamObject does not refer to data containing the association tag. CLDSM_ERR_OBJECT_NOT_LOADED The streamObject does not refer to a loaded object. CLDSM_ERR_OBJECT_NOT_OPEN The streamObject does not refer to an open object. CLDSM_ERR_UNABLE_TO_GET_PROGRAM_ASSOC_TAG No BIOP_PROGRAM_USE tap could be found. CLDSM_ERR_SI_QUERY_FAILED SI Query Failed CLDSM_OK Association Tag was successfully obtained.

clDsmErr_t dsmStreamGetProgramAssocTag	(	clDsmObjHandle_t	streamObjectHandle,
		U16BIT *	pAssociation_tag
	)

The Client calls this function to obtain the Association Tag which can be used to determine the PID on which stream data can be found. Before calling this function the Client must have completed loading and opened the stream object.

Parameters

streamObjectHandle	This handle indicates the stream object for which the association tag is required.
pAssociation_tag	This value is indirectly used by the Client to access elementary stream data, i.e. video/audio PIDs.

Returns: CLDSM_ERR_INVALID_OBJECT_HANDLE The supplied object handle was not valid. CLDSM_ERR_INVALID_OBJECT_TYPE The streamObjectHandle does not refer to data containing the association tag. CLDSM_ERR_OBJECT_NOT_LOADED The streamObjectHandle does not refer to a loaded object. CLDSM_ERR_OBJECT_NOT_OPEN The streamObjectHandle does not refer to an open object. CLDSM_ERR_UNABLE_TO_GET_PROGRAM_ASSOC_TAG No BIOP_PROGRAM_USE tap could be found. CLDSM_OK Association Tag was successfully obtained.
