2 HD/SD SDI + 2 HDMI Broadcast MPEG2 & H.264 1080p Encoder IPTV and ASI

I have a question and would appreciate your support as we are nearing the end of the project. Unfortunately, the client does not have a defined layout or topology. However, in summary, the setup is as follows: each device is connected through the LAN network using an IP address. The decoders are connected to the TVs via HDMI, and each decoder is assigned an IP address connected to the network. All the devices are online, and I have reviewed the manuals. However, I have not been able to find instructions on how to integrate the TVs with the Digital TV modulator equipment using the Ethernet network. I would greatly appreciate your help. --------------- 2 To summarize what he recommends, assign an IP address to each H-IP-HDMI manually (since there is no HDCP server). This equipment would connect to the TV via HDMI and to the Hospital network through its RJ45 port. On the H-IP-HDMI equipment, only the port and the channel would be configured. On the other hand, in the case of the H-2SDI-2HDMI-ENC equipment, the channel would be assigned to control the TVs. ----------------3 I want to clarify that I have already assigned an IP address to the encoder for integration into the network. Now, what I need to do is assign an IP address to the decoder that connects to the TV. Our project scope is limited to installing the encoder and 43 decoders, which are connected to the TV using HDMI and to the network using RJ45. The responsibility for the TV headend lies with the client. However, the client has requested a test, and they do not currently have TV service. Is there a way to display or transmit a video that can be replicated on the televisions for testing purposes?
