cReceiver::cReceiver | ( | const cChannel * | Channel = NULL , |
int | Priority = MINPRIORITY |
||
) |
Creates a new receiver for the given Channel with the given Priority.
If Channel is not NULL, its pids are set by a call to SetPids(). Otherwise pids can be added to the receiver by separate calls to the AddPid[s] functions. The total number of PIDs added to a receiver must not exceed MAXRECEIVEPIDS. Priority may be any value in the range MINPRIORITY...MAXPRIORITY. Negative values indicate that this cReceiver may be detached at any time in favor of a timer recording or live viewing (without blocking the cDevice it is attached to).

This function is called just before the cReceiver gets attached to (On == true) and right after it gets detached from (On == false) a cDevice.
It can be used to do things like starting/stopping a thread. It is guaranteed that Receive() will not be called before Activate(true).
Reimplemented in cTransfer, and cTransfer.

Returns true if this receiver is (still) attached to a device.
A receiver may be automatically detached from its device in case the device is needed otherwise, so code that uses a cReceiver should repeatedly check whether it is still attached, and if it isn't, delete it (or take any other appropriate measures).

This function is called from the cDevice we are attached to, and delivers one TS packet from the set of PIDs the cReceiver has requested.
The data packet must be accepted immediately, and the call must return as soon as possible, without any unnecessary delay. Each TS packet will be delivered only ONCE, so the cReceiver must make sure that it will be able to buffer the data if necessary.
Implemented in cLiveSubtitle, cTransfer, and cTransfer.

bool cReceiver::SetPids | ( | const cChannel * | Channel | ) |
Sets the PIDs of this receiver to those of the given Channel, replacing any previously stored PIDs.
If Channel is NULL, all PIDs will be cleared. Parameters in the Setup may control whether certain types of PIDs (like Dolby Digital, for instance) are actually set. The Channel's ID is stored and can later be retrieved through ChannelID(). The ChannelID is necessary to allow the device that will be used for this receiver to detect and store whether the channel can be decrypted in case this is an encrypted channel.
