Post Hello, I need information about Online Broadcasting TV under Linux.


[SIZE="2"]Hello, I am new to this community. When i mean new i mean I didn't even started to craw like a baby. I am sorry if i had choose the wrong forum to post but i hope this is the most suitable place. I would ask if someone can give me some suitable literature in the web about ONLINE TV BROADCASTING under/with LINUX SERVER, i am not sure even how to spell it correctly, because i never had a need of such NFO. I need any kind of information regarding ONLINE TV BROADCASTING. I tryed but maybe my tryes are not hard enough to find something in the web, i know such information is not widespread. Thank you and excuse me if i disturbed the order of this place.[/SIZE][/SIZE]

Thank you about the link, but the NFO i need is quite different. I would like to know how is the chain moving in question, i will explain it as simple as i know it :

1. Television information flow on a cable,
2. The cable enters a convertor that transmutes and convert the signal into a digital one,
3. The digital signal enters a Linux broadcasting server that transfers it over the net into some website where you can watch online some TV.

I would like to ask how is this happening ? If i dare to know also, how can you make one ? I am almost sure that anyone that know such information wont even bother to post it. In our present time, and not only in our time information always has a cost.

People who know the details of how this works WILL post---but not necessarily at LQ. Google should find something.

One thing to be aware of: Many Internet providers (ISPs) will not allow you to do this (and your upload speed may not be fast enough).

I know they wont allow me to do this. I don't even think about doing it. My current job needs knowledge about Linux Servers that broadcast online TV. I checked Google, first thing i did, only companies offering their products. I can say its flood of them. Just need some info.

Linux will be good at streaming anything, and makes a secure server. Look at what comes with a tv card. tv --> disk and disk --> internet should be doable. TV --> encoding --> internet may be doable if you have a suitably resourced setup.

I think you need to put a shape on this instead of making general enquiries. Your TV signal is an extremely unwieldy thing to send online, and tv output isn't much use to a pc monitor so you're going to compress it into a known format. When you say 'tv' do you mean PAL, SECAM, or NTSC? Look for ways
1. To get these into your pc as data - a pci card I imagine.
2. to put whichever (pal, ntsc, secam) you need into mpeg-something

Then come back and if you have trouble getting this out, we'll know what you are trying to do at least.

you probably should start with a linux friendly video capture card that will save the video/audio data as a mpeg/avi/mkv/xvid/... file (which one are you using ?).

then you can broadcast that file on the internet somehow (html link/ netcat, maybe).

then you can think about ways to broadcast on the internet in real-time.

I would just add that 'real time' is a relative thing. You may indeed do better with a few boxes - 1 to take in video & encode, one as a server. If you are broadcasting events, there will be variable load on the server

vlc will stream video over your LAN (and, presumably the internet, if your ISP and source of the video allow it):
