Live Tv Streaming
« on: October 16, 2003, 02:46:00 AM »
Is it possible to stream live picture from PC's TV-card to Xbox using RelaX or some other streaming server? I have a satellite dish on top of my roof and I just ordered digital satellite receiver to get some more channels. Everything is OK this far, but I just noticed that antenna cable of the dish is going to downstairs and I have my home theater installed at upstairs. Moving antenna cable to upstairs would require some cabling that I cannot do myself (cause I want it to look good and cabling to be done inside the walls). I have my computer room downstairs and it's connected to upstairs (Xbox there) using WLAN.

I have good quality TV-card installed in one of my computers, so what I'm looking here is to connect satellite receiver into this computer using S-VIDEO / digital (optical) audio input and stream this input into upstairs using WLAN connection. Quality of the picture should be good and audio playback should support Dolby Digital / AC3. I know that this isn't the best possible solution cause of the fact that I cannot easily control my receiver from upstairs, but this would be only temp solution until I get some professional to work with the cabling. Any ideas or suggestions?

at one point I heard there was going to be snapstream support.

I bought a copy and even gave a beta to the devs...still havent heard ANYTHING about it.

I guess WLAN is not the best possible for this, but my home WLAN speed is 54Mb (~ half from normal 100Mb LAN speed, 5-6Mbytes per second), so I guess it should be easily enough for decent quality. For example when comparing to XviD quality that has normally 1000-2000kbit for video and 192-500kbit for AC3 audio. Maybe I'm not counting right, but seems like there is plenty of bandwith for this kind of implementation.

PC hardware is not a problem either. PC that i'm going to use has 3GHz P4 CPU and fast DDR 400MHz memory with ATA/133 RAID with striping. Not sure what you meaned with needed equipment for AC3 encoding, but what I have is a card with optical input which I guess should be enough with some software encoder.

But the problem isn't really in the bandwith nor in hardware. It's just that I want to use stream, not some recorded video clip. What I understood was that I should put my PC to record the ongoing TV feed into some folder and configure that into RelaX + Xbox, but I don't want to record or save anything. I want to take the picture + audio and just simply stream it into my Xbox without having the stuff on my local disk. Normally streaming means connecting into some specific port which then provides the feed, just like XBMP does with RelaX. So I guess what I'm really looking here is a software or multiple softwares that together that can stream input from my video and audio devices with decent quality into format that Xbox can understand somehow and this all should happen in real time and using on-the-fly encoding.

I did some research and founded project called MythTV for Linux that should run OK in Xbox too. I guess this is the only choice that I can use to get this thing working properly. MythTV has all what is needed. Backend computer that provides the stream (downstairs computer) and frontend computer that controls the stream (Xbox). It even provides a way how to control my satellite receiver from the frontend computer, so I guess I'll just use this project and forget my dreams about using XBMP fo this (native application would have been a lot more nicer to have).

I'm also interested in streaming MPG2 files... I have a Twinhan 1020 ( a DVB-S card) witch is directly connect to the dish, no IRD needed :-)

I use ProgDVB, which is a streamer decoder/playback sofware. It already have a broadcast ability ( 1 chanel need 3 Mb/s of bandwith, hole trasponder 30 Mbs ( 7-8 chanel)) witch can be  serve by a MPG2 stream server ( dunno witch one... if ther is one... but the auther au ProgDVB tell there is)

The advantage with this is you saw what provider send, no need to reencode the stream and ProgDVB can be command by command line... so a xbox aplication could be made to control the sofware and change chanel :-)

I will do some test between 2 computer to beging with and let you know...
