The IPTV input are received through the Link ports and the following requirements must be satisfied:
- IP multicast streaming (UDP streaming)
- Possibility of RTP
- Possibility of IGMP version 2
- SPTS or MPTS including PAT, PMT, CAT
- IPTV-input license
Important:
The TDX headend system supports up to 7 TS packets per IP packet at IP inputs.
The TDX headend system does not support IP fragmentation at IP inputs, which may occur if the IP packets are transmitted over a network with a Maximum Transmission Unit (MTU) less than approximately 80 + N*188 bytes, where N is the number of packets per IP packet..
Recommended settings are 7 TS packets per IP packet and a minimum MTU of 1500 bytes in the entire network path.
The link ports can be used with Copper RJ45 or Fiber SFP modules.
Preparing the headend for networking
We will have to prepare the TDX headend for working with a network-switch.
Go to the admin section -> IP settings and click Enter setup (Edit link IP settings for system).
Select Switch and modify the LINK IP-adresses / subnet mask if needed.
The headend will reboot after these changes.
Configuring the IP-input
Select the INPUT tab and the Link 1 or 2 with the IPTV input.
Enter the incoming multicast address and port.
In this example: 239.1.1.1:1234
The incoming service(s) will be listed
If the SDT is not included, the TV-service name will be "Service ID x".
The service can then be renamed and selected (put in the TDX pool).
Just "double click" the service name and enter the new name.
Select the service and submit.
An example with an incoming IPTV MPTS multicast (which includes the SDT).
All TV-service names are shown based on the SDT.
The selected TV-services are available in the TDX pool and can be used for output.
Note: The IPTV-input licenses are available from the Product Registration Tool (PRT).
