Detailed Description

+A receiver for live TV

+This is a receiver object which is attached to a VDR tv card device. It is receiving transport stream packages and generates a single MPEG2 transport stream which can be distributed through the network.

+
+ + + + + + + + + +
void cLiveReceiver::Action (void   )  [protected, virtual]
+
+
+ +

+The receiver thread action

+This actually is the receiver thread, which runs consequitivelly and buffers any received video data from the interal incoming buffer to the internal outgoing buffer.

+While doing so, it tries to syncronize with the stream and creates new MPEG2-TS PATs and PMTs for a single MPEG2-TS stream +

+

+ +

+
+ + + + + + + + + +
void cLiveReceiver::Activate (bool  On  )  [protected, virtual]
+
+
+ +

+Activates the receiver

+This activates the receiver which initializes internal data structures to be prepared for receiving data from the VDR

+If the parameter is true, the receiver will be activated. If it is false, the receiver will be deactivated and stops its threads.

Parameters:
+ + +
On Activates the receiver thread
+
+ +
+

+ +

+
+ + + + + + + + +
void cLiveReceiver::close (  )  [virtual]
+
+
+ +

+Closes the open file

+This will close open file handles and frees the memory obtained by it. +

Implements cFileHandle.

+ +
+

+ +

+
+ + + + + + + + + + + + + + + + + + +
cLiveReceiver * cLiveReceiver::newInstance (cChannel *  Channel,
int  Priority 
) [static]
+
+
+ +

+Creates a new receiver instance

+This will create a new instance of a live receiver for the specified channel at the specified priority level.

+A negativ priority means that the receiver may being detached from a device.

+The receiver must be free'd with delete after it is not used anylonger.

+

Returns:
returns a new liveReceiver instance
+
Parameters:
+ + + +
Channel the channel which shall be tuned
Priority the priority level
+
+ +
+

+ +

+
+ + + + + + + + + +
void cLiveReceiver::open (UpnpOpenFileMode  mode  )  [virtual]
+
+
+ +

+Opens the file

+Opens the file at the given mode. These can be:

    +
  • UPNP_READ, to read from the file
  • UPNP_WRITE, to write to the file
+

+

Parameters:
+ + +
mode The file mode, i.e. one of the following
    +
  • UPNP_READ
  • UPNP_WRITE
+
+
+ +

Implements cFileHandle.

+ +
+

+ +

+
+ + + + + + + + + + + + + + + + + + +
int cLiveReceiver::read (char *  buf,
size_t  buflen 
) [virtual]
+
+
+ +

+Reads from the file

+Reads from the file a certain amount of bytes and stores them in a buffer

+

Returns:
returns
    +
  • <0, in case of an error
  • 0, when reading was successful
+
+
Parameters:
+ + + +
buf The char buffer
buflen The size of the buffer
+
+ +

Implements cFileHandle.

+ +
+

+ +

+
+ + + + + + + + + + + + + + + + + + +
void cLiveReceiver::Receive (uchar *  Data,
int  Length 
) [protected, virtual]
+
+
+ +

+Receives data from VDR

+This is the interface for receiving packet data from the VDR. It buffers the incoming transport stream packets in a linear ringbuffer and returns immediatelly

Parameters:
+ + + +
Data The data received from VDR
Length The length of the data packet, usually 188 bytes
+
+ +
+

+ +

+
+ + + + + + + + + + + + + + + + + + +
int cLiveReceiver::seek (off_t  offset,
int  whence 
) [virtual]
+
+
+ +

+Seeks in the file

+Seeks in the file where the offset is the relativ position depending on the second parameter. This means, in case of

+

    +
  • SEEK_SET, the offset is relative to the beginning of the file
  • SEEK_CUR, it is relative to the current position or
  • SEEK_END, relative to the end of the file.
+

+

Returns:
returns
    +
  • <0, in case of an error
  • 0, when reading was successful
+
+
Parameters:
+ + + +
offset The byte offset in the file
whence one of the following
    +
  • SEEK_SET,
  • SEEK_CUR,
  • SEEK_END
+
+
+ +

Implements cFileHandle.

+ +
+

+ +

+
+ + + + + + + + + + + + + + + + + + +
int cLiveReceiver::write (char *  buf,
size_t  buflen 
) [virtual]
+
+
+ +

+Writes to the file

+Writes to the file a certain amount of bytes which are stored in a buffer

+

Returns:
returns
    +
  • <0, in case of an error
  • 0, when reading was successful
+
+
Parameters:
+ + + +
buf The char buffer
buflen The size of the buffer
+
+ +

Implements cFileHandle.
