Firewire is better for video, because firewire is a more sophisticated interface. Firewire provides for device to device communication, DMA transfers and other performance features that USB does not. Therefore Firewire does not rely on the host computer's CPU. USB does not provide DMA transfers. All data on the USB bus must be managed by the CPU loading it ...

For the best quality and/or High Definition you want to use the fastest computer input you have that your streaming app will accept. That would normally be Firewire. Most online streaming sites will accept both USB or Firewire.

Unfortunately there is no perfect or exact answer. Your question topic mentions HD-SDI, which is a digital signal. Those tends to degrade 'cliff-wise', unlike analog signals where degradation is gradual. It will partly depend on the quality of the receiving device -- whether or not, or how well, it can capture the signal as the eye pattern turns to mush.

What you are talking about is upscaling and any current HDTV will do upscaling automatically. Upscaling doesn't work miracles though, it will only make it so that the lower quality signal can be watched on a higher quality display. It just multiplies the pixels so that a 720 by 480 (.9 pixel compressed) signal for example doesn't end up only taking up 1/4 ...

EasyCap 2.0 DC60+ is what I use, and they work great. Make sure you get the DC60+ version, you don't want the older versions.
There are a lot of knock-offs floating around--I'd stick with the official one.
There's also a good compilation of capture cards on this thread on the Wirecast Forum.

It is extremely simple, and a quick google using the title of your question will show you many sites explaining how to do it. Two simplest options are:
Use software such as MP3MyMP3recorder or Freecorder, which can record directly in software. This is the simplest physically, just giving you an output file from your input stream.
Use a cable to connect ...

I'd agree with @filzilla. However, if you're set on doing this, there's information you'll need to, if nothing else, educate yourself as a consumer.
First: the items shown on the svideo site will work adequately. You may get sides of the computer image cut off on the TV, unpredictably, I may add, depending on the electronics.
Second: If you want (or ...

Your comparison of WMV to MP4 is a little bit confusing, because you're comparing apples and oranges.
MP4 is a container format, which may contain a variety of audio and video formats. Most commonly, an MP4 file will contain wither an MPEG-4 Part 10 (aka H.264) or MPEG-4 Part 2 video stream, although it can contain MPEG-2 or MPEG-1 video streams. There ...

The cabling is likely your problem. The composite cables you're using (red, yellow, white) will only move analog signal from the set top box to the TV. Likewise with RG59 or RG6 (coaxial).
While both varieties of cables there are technically capable of passing digital signals (they don't care... they're just dumb cables), set top boxes typically only ...

The next step would be mic'ing up your entire band through one mixing console, like you would for a live show, and running a stereo mix out of the console and in to your computer via a line in on a sound card and streaming that mix.
You wouldn't necessarily need a full-on dedicated mixing console to achieve this. You might be able to get away with something ...

For a server, you definitely want ffmpeg. I would also strongly recommend compiling it yourself (those are Ubuntu instructions, but should work for Debian as well AFAIK) - the best AAC encoder available for ffmpeg (libfdk_aac) cannot be redistributed alongside x264 (because of the GPL), and the version of ffmpeg in the repositories is probably too old for ...

Blackmagic and Livestream are your friends :)
You probably want to get 3 cameras - one for the priest, one for roaming action shots and one for the audience. You'll need a whole bunch of microphones and an audio mixer. But you probably already know all this.
Buy a Blackmagic TV Studio and buy a Livestream Broadcaster - plug the TV Studio's HDMI output into ...

For amateur events, SDI may be overkill compared to using simple Component. The key for long runs is to separate the various components so that they don't degrade. There is a similar question here about long distance runs.
As for HDMI to SDI, there should be no quality loss compared to HDMI as both are digital formats supporting full uncompressed HD ...

Solved the problem...
Go to: Mac System Preferences > Blackmagic Design
Set default video standard as HD 1080i 59.94 CamTwist > Blackmagic HD 1080i 59.94 - 8 Bit
I figured out my camera settings using the Blackmagic Media Express app, which did detect the camera. Just take a look in the app's settings to find your camera's connection settings.

Yes, this is totally possible as long as you have the ability to do a key. You can either do a luma, chroma or alpha key. It's the same as when the weatherman does the weather, but you switch the sources.
You would record whatever you wanted to be able to lay over top of the stream with either a dark background, a mono-color background, or a rotoscoped ...

I found this rack mount device called DVEO D-Streamer IP/DIG. One of DVEO's press relises announced $4000 price for the device.
Inputs: HTTP Live (HLS), UDP, RTP, RTSP, HTTP, RTMP (Open Flash), MMS.
Output: SD/HD-SDI.

The Easycap Capture adapter is simply a video capture device with no TV tuner, so you would not be able to receive any TV signal.
I would recommend the USB TV tuner. I'm not sure whether you will need an Analog or Digital tuner as this will vary according to where you live (here in the U.S. all stations are now Digital). If you are putting this into a ...

Video transcoding is very confusing and there is loads of different options.
If you dont want to use FFMpeg you could try VLC
Read more about transcoding with VLC here
Otherwise FFMpeg (or some kind of wrapper tool) is your best bet.
By omitting the -vb option you let FFMpeg decide bitrate. There is also a few Presets you can use for encoding to specific ...

Why not use existing services?
I’ve been using a Shoutcast streaming plan for years to broadcast my church’s services live. It’s worked like a champ.
Part 1 – Audio Capture
I’ve been using an old P2 Win98 box for years with an older version of Winamp & the Shoutcast plug-in. (There are of course modern versions of those.) “SAM Broadcaster” is a very ...

Lithiumhosting is a great provider of streaming audio over the internet. They are pretty cheap too. I use their webservers and I am very pleased with their service!
As to what softwares you should use. It depends on how much money you are willing to put into it. A good way of doing it would be to use an analog mixing board and send the audio into the ...

Check out Wowza - it should do what you want. The basic premise of Wowza is video in, video out. It can take multiple video streams into it's encoding engine, and spit them out in various formats, live.
If you've got 4 inputs (let's assume they're cameras with HDMI output), you need a computer with 4x HDMI input cards (or 2x computers with 2x cards, ...

You may want to read the spec for Apple's HTTP Live Streaming
and see their recommended settings.
While the standard seems to be quite well thought through, its real-world performance on iOS still needs some improvement. Switching qualities and streams (for ads) often results in less than stellar experiences. Encoder support also needs to be more ...

PulseAudio should do what you want. There are client and server components for Linux, Mac and Windows.
PulseAudio will create a virtual audio device on your Windows machine. All sound coming to that can get routed over the network to your clients.

Simple, use IceCast.
Free, open-source, cross-platform.
I interface to IceCast using Edcast (on Windows), allowing broadcast of audio in both vorbis and mp3 formats. (I think AAC as well!)
Have fun!

You might try justin.tv
but since its a bigger thing you want to stream and streaming bandwith is very expensive it will end sooner or later in a paid solution.
livestream.com or watershed.ustream.tv could be interesting Hosts then.
But if you find some cheap to free alternative without (much) advertisement, let me know :)

This question doesn't really make sense as it is now--the quality of your YouTube videos should have nothing to do with livestreaming.
If your camera takes good video to begin with and the videos look fine on YouTube, then the problem with livestreaming is going to be the upload bandwidth of your internet connection. If you don't have the bandwidth, the ...

What you are asking is extremely difficult without some very expensive and complex software and video studio equipment. I learned some techniques in After Effects that were supposed to make an enlarged video look better (certain blurs and sharpeners, deinterlacing, etc) but I was NEVER satisfied with the results. Every technique made the enlarged version ...

If you want to stream with Justin.TV, you can download FFSplit !
http://www.ffsplit.com/
It is still in a BETA State, but it does run quite well !
Don't forget to follow every instruction that is put on the site.
Good luck !

If you are on Mac, I'd recommend creating a script in some scripting language, like Perl or PHP, which runs every minute and keeps a local folder of sound files up to date with that's on your soundcloud dropbox.
You could then have your Max patch watch this local folder and pull in new files as they arrive. I would not try to make Max pull sound files ...

I think this could be a way of building the application:
Have a client side script that reads the list of tracks from the soundcloud api:
I couldnt find a way to get the dropbox contents, but maybe you could create a group and that way it will be easier to moderate the tracks and you could ask the api for them with something like:
GET /groups/{id}/tracks
