I would like to raise a discussion about VDR compliance with a wide range available STBs (Set-Top-Box) for IPTV carrier integration.

The advantage of such compliance is obvious - low cost of STB. The cost of STB is in the range of 80-150 USD.

I'm not sure about what you're actually talking. Do you want VDR to act as IPTV receiver, do you want VDR to act as a relay from classic digital TV to IPTV boxes, do you want some IPTV box with VDR as software, or do you want to use a IPTV box as VDR remote front end?

The last one is true :) IPTV STBs usually are very limited, I doubt that VDR can be loaded on it. While it ideal low-cost remote frontend staff.

...

The compliance is actually matter of:

1. multicast MPEG-TS streaming support;

As for receiving multicast, this is possible with streamplayer plugin. Transmitting could be done with VLC and streamdev - or even with VLC alone.

Yes, that's true. VLC and streamdev i had in mind but that is not tided with VDR and could work as an proof of concept so far.

...

2. vdradmin support for multiuser STB environment.

I'm not sure what this is supposed to be.

In order to interact from IPTV STBs with backend the middle-ware required. The main role of middle-ware to reply on http requests and provide either RTSP URL or multicast group to STB. Basically middle-ware is a kind of web site that take in to account that STB could overlay http page on a top of video received via multicast. In theory vdradmin could be extended to support IPTV STBs.

Cheers,

Udo

I have more or less a proof-of-concept of what you want done. The problem is that is was done as a proof-of-concept and is just that is kludgy at best :-)

1) multicast MPEG-TS streaming support;

This is actually quite simple to implement, and is not that dificult do do in a plugin, that's what I did, I just implemented a Receiver Plugin, that get the TS packets, adds PAT and PMT and send that stream to a multicast address. Everything quite hard coded, but it works, and shows how it could be done.

Sounds very interesting! Is it possible to get it and test?

2) vdradmin support for multiuser STB environment.

That I never did, just some SVDRP commands via .php, and no HTML overlay (I know that it's possible I just did it as proof-of-concept never to release or anything).

Above development could affect the design of VDR in general, I would
like to discuss it in details. 

I'm all for it, if anyone want my crude code and improve on it and understand what I mean by kludgy and crude, it's ok to me.

Cumps,

Bernardo Cardoso
