Function Documentation

DSI_CancelTable()

void DSI_CancelTable	(	H_DsiInstance	dsi,
		U32BIT	rid
	)

Cancel request for table data made by DSI_RequestTable()

Parameters

dsi	DSI instance handle
rid	Request Id returned by DSI_RequestTable()

Returns

void

DSI_CheckRequests()

U32BIT DSI_CheckRequests	(	H_DsiInstance	dsi,
		U32BIT	now
	)

Check outstanding PMT (and PAT) requests to see whether any need to be refreshed.

Parameters

dsi	DSI instance handle

Returns

U32BIT time when need to call this function again

DSI_CreateInstance()

H_DsiInstance DSI_CreateInstance	(	H_DsmControl	ctrl,
		F_FILTER_CALLBACK	cbfunc,
		S_DsmccConfig *	config
	)

Create instance of DSI.

Parameters

cbfunc	Function to process SI section data
config	Configuration of DSM-CC

Returns

DSI Instance handle

DSI_DestroyInstance()

void DSI_DestroyInstance

(

H_DsiInstance

dsi

)

Destroy instance created by SIQ_CreateInstance.

Parameters

H_DsiInstance

dsi DSI instance handle.

Returns

DSI_RequestTable()

U32BIT DSI_RequestTable	(	H_DsiInstance	dsi,
		U16BIT	pid,
		U16BIT	xid,
		U8BIT	tid
	)

Request Table data. It supplies Table soon after the call to this function, and then, whenever the Table version changes. This state continues until DSI_CancelTable is called.

Parameters

dsi	DSI instance handle
pid	PID for this table
xid	Table extension ID
tid	Table ID (e.g. PMT is 0x02)

Returns

zero is failure, non-zero is success

DSI_RequireTable()

BOOLEAN DSI_RequireTable	(	H_DsiInstance	dsi,
		U8BIT *	hdr,
		U16BIT *	pXid,
		U8BIT *	pVer
	)

Check whether SI table section data is required.

Parameters

dsi	DSI instance handle
data	pointer to section data (starting at table Id byte
pXid	pointer to return table extension
pVer	pointer to return table version

Returns

BOOLEAN - TRUE if required, otherwise FALSE

DSI_Start()

BOOLEAN DSI_Start	(	H_DsiInstance	dsi,
		U16BIT	transId,
		DMXREF	dmxref
	)

Start getting SI data from Demux.

Parameters

H_DsiInstance	dsi DSI instance handle.
DMXREF	dmxref Demux reference handle

Returns

Parameters

dsi	DSI instance handle.
transId	Transport stream ID
dmxref	Demux reference handle

Returns

DSI_Stop()

void DSI_Stop

(

H_DsiInstance

dsi

)

Stop getting SI data from Demux.

Parameters

H_DsiInstance

dsi DSI instance handle.

Returns
