How does IPTV work? Why does it need its own protocol?
 

It doesn't make any sense to me
I obviously cannot get it without a way out to the internet, right?
Why don't they just use regular TCP IP ?
What is this, like a VPN for television?
Can I get channels and stations with Russian women? I am so curious about Russian women, these days. FFS





PS: The board told me this and I think I posted a few days ago, maybe..

Hello MrMaxwell it appears that you have not posted on our forums in several weeks, why not take a few moments to ask a question, help provide a solution or just engage in a conversation with another member in any one of our forums?

Can I use a DVR with this bullshit? Also, cox recently capped our transfer so I guess I'm fucked on this for now. But it sure is interesting

Just like ICA Protocol for Citrix. Sometimes the bare TCP cant hold enough info

I am still a little lost
I have used up to 1 gigabit connections getting around 700 megabit speeds and was using TCP IP 4 (as far as I was aware, anyway... I didn't actually look, I suppose)
I mean when you say information you mean data, right,

I am confused
Sorry if I sound ridiculous

An error correcting protocol (like TCP) isn't good for a time sensitive stream which can handle occasional corruption. As soon as TCP loses a packet the stream will stall as the source first detects the loss, then performs a retransmission.

Better to have someone's head go blocky for the next half second due to a missed data packet, rather than have the whole picture freeze.

Multicast: If you are referring to streams without long delay (short buffer times), usually IGMP is being used, due to an easy way to distribute streams to multiple users, using UDP broadcast (IGMP uses RTP over UDP). You can not use multicast on a WiFi connection, so you need some sort of a cable/fiber.

Unicast: At the moment my ISP is using IPTV with HTTP streams (RTSP over TCP) and it works without any problems. I think they are using Wowza, and I see no problems broadcasting it over WiFi. It's not some internet service off of web, but a real regular ISP, which means HTTP streaming is very much possible with IPTV. Probably not the best solution for live event streams (basically any sports event), but the lag is definitely shorter than satellite streams.

You can read more about IPTV protocols here: https://en.wikipedia.org/wiki/IPTV#Protocols

My router had an option for Multicast forwarding or some shit but I'm still a little lost
It makes sense that the TCP protocol isn't good for the type of data video is I suppose
You essentially are saying that tcp is inefficient and unreliable when you're sending compressed video over it?

So I guess TCP would be better for a bit for bit copy and this other shit would be good for video because it can live with not being 1000% correct data

I think there was some talk about when broadcasting a show it can be forwarded and sent to multiple addresses at once (multicast) without sending the entire stream to each person individually. That way if the stream is 1 Mbps and you have to send it to 100 people it isn't 100 Mbps.

FFS - that must save a FUCKTON of BW!!! Wow. Multicast sounds awesome
What keeps all of it synced? I mean each moron isn't watching the same part of the film all at once... so how does that work? I know servers are making huge advancements in caching and all
