cCamSlot::cCamSlot | ( | cCiAdapter * | CiAdapter, |
bool | WantsTsData = false |

) |
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.

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

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

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 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. There are three possible ways a CAM can handle decryption:

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.
