I have the setup below. I'd like to know how this whole setup works as far as the multicast is concerned. What is the path that the video takes. It looks like the video is either or both coming from Comcast or xfinity. It is then going through the decoder, then to the switch for the internal network. The encoder is also connected to the switch. Thx

The traffic will simply go Encoder -> Catalyst Switch -> Internal LAN

If the multicast stream is coming from the Encoder to the Internal LAN on the same VLAN you should use IGMP snooping on all of the switches.

Is this a video stream from Comcast or xfinity coming to the internal LAN? So how will the users see the video stream? I see that there are some digital media player connected to the switch. Is it related to the multicast traffic? Sorry I am trying to understand how this whole thing works. Thx

You need to tell me that.  I can only guess that it's coming in via the Comcast or Xfinity switches, as you implied already.

The stream will come in via Comcast or Xfinity and will be converted from analog to IP via the decoder.  The encoder will pull the IP stream from the decoder via unicast and push it out via unicast or multicast (depending on how it's configured).  The Internal LAN Catalyst switch will then allow clients on the Internal LAN to see the multicast stream via IGMP (or PIM if routed between VLANs).

I understand better now: analog converted to IP by decoder and encoder pulls IP stream via multicast (I think it is multicast when it is going to the LAN). I don't think there is multicast routing as the internal network is all layer 2 switches and I don't see any igmp on the router that is doing the intervlan routing. Thx
