I am looking into getting a live stream set up. doing a one camera shoot through a lap top running wireacst. What are my minimum up and down speeds for viewing the different window dimensions? Is there anywhere where I can see a comparative list? Before I submit my proposal I'd like to know what is possible.
ideally id like to use one of these. Am i dreaming?
Assuming I have the video streaming to certain locations with a garaunteed line speed, Is it possible to simultaneously send out another stream of a smaller size to a general home user audience?
Or would i be better to record the stream and delay the presentation till after the heavier stream has completed?
Streaming at those resolutions - 720p HD (1280x720) or 1080p Full HD (1920x1080) you will generally need an upload connection of 2.5Mbps-4Mbps to produce an end result that looks good. Your viewers will need 1.5 times that speed to ensure smooth playback.
So - It is possible, but challenging.
You can definitely use Multi-Bitrate streaming to supply a low/high quality stream based on the end-user's connection speed. I believe the feature is available in WireCast.
