- The CAM handling has been refactored. 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. IF AN ENCRYPTED CHANNEL CAN'T BE DECRYPTED AND YOU HAVE A CA VALUE IN THE RANGE 0...F FOR THAT CHANNEL, SET IT TO 0 (FTA) AND TUNE TO THE CHANNEL AGAIN.
Video Disk Recorder ('VDR')
---------------------------
These files contain the source code of the "Video Disk Recorder",
which is based on the DVB driver of the LinuxTV project (http://linuxtv.org).
For details about the "Video Disk Recorder" project please
refer to http://www.cadsoft.de/vdr.
There is also a remote control unit described on those
Web pages, which can be used within this program.
Please see the INSTALL file for details on how to install
this program on your computer.
The MANUAL file describes how to operate the VDR.
The CONTRIBUTORS file lists all the people who have contributed to the
development of VDR.

Yet another "set-top box"?
--------------------------
The "set-top boxes" available from commercial companies all have
one major drawback: they are not "open". This project's goal is
to build an "open" digital satellite receiver and timer controlled
video disk recorder, based upon open standards and freely available
driver software (of course, the hardware still has to be bought).
The on screen menu system is simple, but shall provide all the
possibilities necessary to perform timer controlled recording,
file management and even "on disk editing". The menus
of commercial set-top boxes usually are a lot more fancy than
the ones in this system, but here we have the full source code
and can modify the menus in whatever way desired.
