There is few plugins for Plex with support TVHeadend.

Yes there are and i have tried them but with HDHomerun emulation it would plug in natively as Plex can then use it with its built in DVR framework. Also it will allow other systems that work with an HDHomerun to use TVHeadend as a server.

Hi,

This is my point of view about this topic:

- HDHomerun (native API, not HTTP) is in general like SAT>IP. So it's good to support it!

Regarding the technical challenge of implementing the "HDHR-Server module" (mimicking the current "SAT>IP server module"), you need to know that:

1. Autodiscovering: The SAT>IP protocol uses SSDP. The HDHR protocol is more simple: single UDP messages over port 65001/udp sended to the LAN over the broadcast address.
2. Control Plane: Custom binary API over a TCP socket (65001/tcp). The API is public and implemented inside a library (https://github.com/Silicondust/libhdhomerun). The state machine is similar to SAT>IP: open tuner, set tunning parameters, set target, close tuner.
3. Transport Plane: Delivery of a regular MPEG-TS over simple UDP or RTP. In this case is more simple than SAT>IP (plain UDP supported).

Drawbacks: The HDHR tuner protocol only supports DVB-T/T2, DVB-C and ATSC. So no DVB-S/S2. Then you need to emulate a Terrestrial tuner (or do some mappings).

Then I feel it's possible to implement it inside TVH. The roadmap can be divided on:

1. Create a "generic" server module based on current SAT>IP. This will work as a "template".
2. Implement the discovery module: very easy!
3. Implement the Transport Plane: first iteration can be a simple UDP reception of the MPEG-TS.
4. Control Plane: This is the hard part of the work. You need to implement several cmd/messages.

But for the last task you can see the implementation done of one true HDHR Emulator for Windows. See it here: https://github.com/dsaupf/HDHRProxyIPTV

I hope this helps! :)

So why Plex not make TVH client itself
you can select then transcoding DVR timeshift etc.

Normally client adapt to server not opposite.

This issue was rejected, because it's dup of #4461 .
