Instead of a cCiHandler per device there + is now an abstract cCiAdapter and a cCamSlot. This allows each slot to be + accessed individually. +- The general 15 seconds workaround time before opening the CAM menu has been + removed. If the CAM menu doesn't open within a timeout, the enter menu command + is now sent again. +- If a CAM is reset or pulled and reinserted, it now automatically starts + decrypting the current channel again. +- The Setup/CAM menu now dynamically refreshes its items and displays whether + a CAM is present or ready. The 'Reset' function no longer leaves the menu. +- The CAM menu will now be openend when pressing the Ok key on a slot entry. +- The CAM menu now stays within the current menu context and doesn't close and + reopen the menu every time an option is selected. +- When an encrypted channel is switched to for the first time, VDR now checks + explicitly whether a CAM can actually decrypt that channel. If there is more + than one CAM in the system that claims to be able to decrypt the channel, + they are all tried in turn. + To make this possible, an encrypted channel needs to be received in Transfer + Mode when it is switched to for the first time, so that VDR can determine + whether the TS packets are actually decrypted. Once a channel is known to + be decrypted by a particular CAM, the next time it is switched to it will + be shown in normal live viewing mode. +- A cDevice now automatically detaches all cReceiver objects that receive PIDs + that can't be decrypted with the current CAM. A plugin that attaches a cReceiver + to a device should therefore watch the receiver's IsAttached() function to + see if it is still attached to the device. +- The cReceiver constructor no longer takes an 'int Ca' as its first parameter, + but rather a 'tChannelID ChannelID'. This is necessary for the device to be + able to determine which CAM a particular channel can be decrypted with. If the + channel is known to be unencrypted, or a plugin doesn't want to provide the + channel id for other reasons, an invalid tChannelID() can be given. +- The cThread::Start() function now waits until a previous incarnation of this + thread has actually stopped. Before this it could happen that a thread's + Cancel(-1) function was called and immediately after that it was started again, + but the Start() function still found it to be 'active'. +- The parameter NeedsDetachReceivers in cDevice::GetDevice(const cChannel *Channel, ...) + has been removed. A call to this function will automatically detach all receivers + from the device if it returns a non-NULL pointer. +- The cTimeMs class now accepts an initial timeout value in its constructor. +- A CAM is now explicitly instructed to stop decrypting when switching away from + an encrypted channel. +- If the CAM in use can decrypt several channels at the same time, VDR can + now make use if this capability. Whether or not a CAM can decrypt more + than one channel is determined by sending it an initial empty QUERY command + and testing whether it replies to it. +- Ca values in the range 0...F in channels.conf can still be used to assign a channel + to a particular device, but this will no longer work with encrypted channels because + without valid CA ids VDR can't decide which CAM slot to use. However, since VDR now + automatically determines which CAM can decrypt which channel, setting fixed + channel/device relations should no longer be necessary. @@ -667,13 +667,15 @@ Version 1.4 Use DiSEqC = no Generally turns DiSEqC support on or off. - CICAM: - - CICAM DVBn m Shows the CAMs that each device contains, where 'n' is - the number of the device, and 'm' is the number of the - Common Interface slot of that device.
