Constructor & Destructor Documentation

◆ cCamSlot()

cCamSlot::cCamSlot	(	cCiAdapter *	CiAdapter,
		bool	WantsTsData = false,
		cCamSlot *	MasterSlot = NULL )

Creates a new CAM slot for the given CiAdapter.

The CiAdapter will take care of deleting the CAM slot, so the caller must not delete it! If WantsTsData is true, the device this CAM slot is assigned to will call the Decrypt() function of this CAM slot, presenting it the complete TS data stream of the encrypted programme, including the CA pids. If this CAM slot is basically the same as an other one, MasterSlot can be given to indicate this. This can be used for instance for CAM slots that can do MTD ("Multi Transponder Decryption"), where the first cCamSlot is created without giving a MasterSlot, and all others are given the first one as their MasterSlot. This can speed up the search for a suitable CAM when tuning to an encrypted channel, and it also makes the Setup/CAM menu clearer because only the master CAM slots will be shown there.

virtual

Adds all PIDs of the given Channel to the current list of PIDs.

void cCamSlot::AddPid	(	int	ProgramNumber,
		int	Pid,
		int	StreamType )

Adds the given PID information to the list of PIDs.

A later call to SetPid() will (de)activate one of these entries.

◆ Assign()

bool cCamSlot::Assign	(	cDevice *	Device,
		bool	Query = false )

virtual

Assigns this CAM slot to the given Device, if this is possible.

If Query is 'true', the CI adapter of this slot only checks whether it can be assigned to the Device, but doesn't actually assign itself to it. Returns true if this slot can be assigned to the Device. If Device is NULL, the slot will be unassigned from any device it was previously assigned to. The value of Query is ignored in that case, and this function always returns 'true'. If a derived class reimplements this function, it can return 'false' if this CAM can't be assigned to the given Device. If the CAM can be assigned to the Device, or if Device is NULL, it must call the base class function.

◆ CanDecrypt()

bool cCamSlot::CanDecrypt	(	const cChannel *	Channel,
		cMtdMapper *	MtdMapper = NULL )

virtual

Returns true if there is a CAM in this slot that is able to decrypt the given Channel (or at least claims to be able to do so).

Since the QUERY/REPLY mechanism for CAMs is pretty unreliable (some CAMs don't reply to queries at all), we always return true if the CAM is currently not decrypting anything. If there is already a channel being decrypted, a call to CanDecrypt() checks whether the CAM can also decrypt the given channel. Only CAMs that have replied to the initial QUERY will perform this check at all. CAMs that never replied to the initial QUERY are assumed not to be able to handle more than one channel at a time. If MtdMapper is given, all SIDs and PIDs will be mapped accordingly.

Reimplemented in cMtdCamSlot.

◆ Decrypt()

uchar * cCamSlot::Decrypt	(	uchar *	Data,
		int &	Count )

virtual

If this is a CAM slot that can be freely assigned to any device, but will not be directly inserted into the full TS data stream in hardware, it can implement this function to be given access to the data in the device's TS buffer.

Data points to a buffer of Count bytes of TS data. The first byte in Data is guaranteed to be a TS_SYNC_BYTE, and Count is at least TS_SIZE. Note that Decrypt() may be called with Data == NULL! This is necessary to allow CAMs that copy the incoming data into a separate buffer to return previously received and decrypted TS packets. If Data is NULL, Count is 0 and must not be modified, and the return value shall point to the next available decrypted TS packet (if any). There are three possible ways a CAM can handle decryption:

If the full TS data is physically routed through the CAM in hardware, there is no need to reimplement this function. The default implementation simply sets Count to TS_SIZE and returns Data.
If the CAM works directly on Data and decrypts the TS "in place" it shall decrypt at least the very first TS packet in Data, set Count to TS_SIZE and return Data. It may decrypt as many TS packets in Data as it wants, but it must decrypt at least the very first TS packet (if at all possible - if, for whatever reasons, it can't decrypt the very first packet, it must return it regardless). Only this very first TS packet will be further processed after the call to this function. The next call will be done with Data pointing to the TS packet immediately following the previous one.
If the CAM needs to copy the data into a buffer of its own, and/or send the data to some file handle for processing and later retrieval, it shall set Count to the number of bytes it has read from Data and return a pointer to the next available decrypted TS packet (which will not be in the memory area pointed to by Data, but rather in some buffer that is under the CAM's control). If no decrypted TS packet is currently available, NULL shall be returned. If no data from Data can currently be processed, Count shall be set to 0 and the same Data pointer will be offered in the next call to Decrypt(). See mtd.h for further requirements if this CAM can do MTD ("Multi Transponder Decryption"). A derived class that implements this function will also need to set the WantsTsData parameter in the call to the base class constructor to true in order to receive the TS data.

◆ StartActivation()

void cCamSlot::StartActivation ( void )

virtual

Puts the CAM in this slot into a mode where an inserted smart card can be activated.

The default action is to make IsActivating() return true, which causes the device this CAM slot is attached to to never automatically detach any receivers with negative priority if the PIDs they want to receive are not decrypted by the CAM. StartActivation() must be called after the CAM slot has been assigned to a device. The CAM slot will stay in activation mode until the CAM begins to decrypt, a call to CancelActivation() is made, or the device is needed for a recording.

◆ StartDecrypting()

void cCamSlot::StartDecrypting ( void )

virtual

Sends all CA_PMT entries to the CAM that have been modified since the last call to this function.

This includes CA_PMTs that have been added or activated, as well as ones that have been deactivated. StartDecrypting() will be called whenever a PID is activated or deactivated.

◆ StopDecrypting()

void cCamSlot::StopDecrypting ( void )

virtual

Clears the list of CA_PMT entries and tells the CAM to stop decrypting.

Note that this function is only called when there are no more PIDs for the CAM to decrypt. There is no symmetry between StartDecrypting() and StopDecrypting().

◆ TriggerResendPmt()

void cCamSlot::TriggerResendPmt ( void )

inline

Tells this CAM slot to resend the list of CA_PMTs to the CAM.

◆ TsPostProcess()

bool cCamSlot::TsPostProcess ( uchar * Data )

virtual

If there is a cCiSession that needs to do additional processing on TS packets (after the CAM has done the decryption), this function will call its TsPostProcess() function to have it do whatever operations are necessary on the given TsPacket.

Returns true if the TsPacket was in any way modified.
