STHD-5514 4-in-1 MPEG-4 AVC/H.264 SDI to IP encoder support audio & video encoding and multiplexing. It can receive 4 SDI signal sources from cameras or HD players as input &1 ASI input, and supporting MPEG4 AVC H264 High Profile code format. The video encoders can multiplex the ASI input TS with the 8 encoded programs SPTS to generate an MPTS output with the inserted PSI/SI information. The SDI encoder output ASI and IP streaming. 

In conclusion, its high integration and cost-effective design make this device widely used in a variety of digital distribution systems such as CATV digital head-end, satellite, and terrestrial digital TV, etc.

How to play the IP stream from the encoder through VLC?

To play the IP stream with UDP protocol by VLC media player, please according to steps below:

1) Connect PC to NMS port of encoder directly(not over any router/switch), open its IP output 

by using multicast address(e.g.;

2) Move the NMS cable from the NMS port to the Data port on the encoder;

3) Try to use a VLC media player to play the multicast stream from the encoder(e.g. URL address in 

VLC is UDP://@ Menu path in VLC is [media] -> [open network stream] -> 

[network] -> [network protocol] <Ctrl+N>, enter the playing address here.

4) If you can’t get the video from step 3, please download Wireshark by Google and set up it, then 

use it to monitor the Data port of the encoder to see if there is an IP packet(see picture below).

5) If you can get IP stream from the Data port of the encoder by VLC, then please check if the encoder

the setting is providing output programs, or refer to the note below.

  •  If the model of the encoder is with a Giga data port, please use the Cat6 network wire and connect 

data port to Giga switch or computer with Giga card.

  •  If you can’t find the stream, please try the following steps: 

1) Check if IP output is enabled on the source device; 

2) Multicast address is suggested, but please use a direct connection between the source and PC 

to avoid switch/router setting issues. 

3) Disable the firewall on the computer; 

4) Disable the wireless network adapter; 

5) Restart the computer; 

6) Run the VLC player again.
