bool cDvbDevice::Bond | ( | cDvbDevice * | Device | ) |
Bonds this device with the given Device, making both of them use the same satellite cable and LNB.
Only DVB-S(2) devices can be bonded. When this function is called, the calling device must not be bonded to any other device. The given Device, however, may already be bonded to an other device. That way several devices can be bonded together. Returns true if the bonding was successful.

Bonds the devices as defined in the given Bondings string.
A bonding is a sequence of device numbers (starting at 1), separated by '+' characters. Several bondings are separated by commas, as in "1+2,3+4+5". Returns false if an error occurred.

Gets exactly one TS packet from the DVR of this device and returns a pointer to it in Data.

Returns true if this device can provide the given channel.
In case the device has cReceivers attached to it, Priority is used to decide whether the caller's request can be honored. The special Priority value IDLEPRIORITY will tell the caller whether this device is principally able to provide the given Channel, regardless of any attached cReceivers. If NeedsDetachReceivers is given, the resulting value in it will tell the caller whether or not it will have to detach any currently attached receivers from this device before calling SwitchChannel. Note that the return value in NeedsDetachReceivers is only meaningful if the function itself actually returns true. The default implementation always returns false, so a derived cDevice class that can provide channels must implement this function.
