TCP Streaming 

 
If in your network occurs packet loss, jitter etc., we recommend using the connection-oriented protocol 
TCP.  TCP  provides  a  point-to-point  connection  (unicast)  for  applications  that  require  reliable 
communications.  If  the  TCP  connection  is  established,  then  the  data  will  be  streamed  in  the  same 
order as it was sent from the encoder. Furthermore, lost packets can be retransmitted via TCP. 
 
The ENC-200

™ and ENC-300™ support TCP streaming in connection with the DEC-300™.  

 
To use TCP streaming on the ENC-

200™ in connection with the DEC-300™, please be sure that your 

encoder  has  the  firmware  version  0.9.29  or  higher,  because  this  firmware  version  is  necessary  for 
TCP streaming.  
 
To use TCP streaming on the ENC-300

™ in connection with the DEC-300™, please be sure that your 

encoder has the firmware version 2.06_w40 or higher, because this firmware version is necessary for 
TCP streaming. 
 
TCP  streaming  is  based  on  the  client/server  architecture.  For  TCP  streaming  with  the  ENC-
200

™/ENC-300™ to DEC-300™ it exists to possibilities:  

 

 

For TCP  streaming  you  can  configure  the  ENC-200

™/ENC-300™ as a server and the DEC-

300

™ as a client. 

 

For  TCP  streaming  you  can  configure  the  ENC-200

™/ENC-300™  as  a  client  and  the  DEC-

300

™ as a server. 

 
The ENC-200

™/ENC-300™ and DEC-300™ configuration changes depending on which client/server 

possibility  do  you  choose.  So,  the  following  subchapters  describe  the  ENC-200

™/ENC-300™  and 

DEC-300

™ configuration for the two possibilities to make a TCP connection.
