Hi:
Have any of you (models or studio managers) thought about how much bandwith is "actually" the minimum accepted by most of cam sites? How much is the minimum recommended upstream bandwith? I am asking this question because I am interested in working in several sites at the same time (I am good at keyboard) but do not want to overload my connection to take the maximum advantage of it. (you know, low costs, high revenues).
Also, a good question is to find out which cam sites demand more and the ones which demand less bandwith to upload video streaming.
A final question, Is it true that streaming audio takes more bandwith than the video itself?
Thanks in advanced for your answers. |

How much upstream the site requires depends on what its using to stream.
Average would be 60kbs to 150kbs +; maybe lower, maybe higher .. Audio should only take 6 - 11kbs to stream.
Alot has to do with the cam, the software, how far you are from the actual server,
what specs your system is etc etc ..
Your best bet is to ask each of the places you sign up with, though chances are they dont know for sure either..... |

i use dsl. people say that cable is faster but i have yet to see a commitment rate of upload from any cable internet provider. if i can be guaranteed a 400 up then...  as for downstream i can be happy with my 1.5Mbps. i am looking out for my upstream always.
from what i have experienced, there are some softwares that hog bandwidth. especially the ones with good refresh rates and those that really give you a smooth stream. there are some softwares webcam sites use that are "thrifty" on bandwidth. but when you have several members watching your video it can be a strain if you have a 128 up. i budget for as much as 3 members watching the feed simultaneously. i wouldnt want a viewer getting a choppy feed and leave a bad impression. i love having returning viewers.  but thats me. |

Well GOG then you are talking about a P2P or yahoo cam because most sites utilize a multicast technology (host to sites server to user), meaning it shouldn’t matter how many members you have in your room, shouldn’t slow up. AWSP basically answered your question, most sites don’t know their actual bandwidth requirements, most just say you need a high speed connection, also most sites don’t talk about a studio/model working multiple sites not owned by them  You will have to play with each site one by one and check it, but again your cam, processor speed, Ram, and speed of internet connection all play a part in working multiple sites. More site software you are running same time uses more processes from your computer and with Windows this causes lockups due to either small processor size or a small ram card. Bigger the processor and Ram cards, generally less headaches running multiple sites.
We created a Virtual Driver (Stream Replicator) that takes less power from your computer, but the catch is you have to work our sites also to use it, close our site down and it freezes the other chats video ...only makes sense  |

umm i do not broadcast multiple sites and have videofeed only on iFriends. they have told us that our feeds do not go to their servers whether that is true or not... well who is to say for sure. but it is explicitly stated on the sign in page we fill out prior to hosting our videochat sessions, all the different videostream softwares that we hosts choose from to transmit our live feed have different requirements. Each have its requirements for upstream bandwidth and computer system. even certain bonus features like multiple camera angles and audio strains bandwidth too. going through some of the sites reviewed here, i have seen sites requiring at least 400 up. so, to the original poster... read and correspond with the site you intend to host with.
as for iFriends these are the softwares and a lil info on each.
FOR IF CAM ifCam works wonderfully even on slower PCs and over slower chathost connections (such as dialup modem). you can control your number of frames, how you deliver your audio and image compression and # of viewers to watch your feed. i have used this with dial up and broadband and it works fine both ways.
FOR EASYCAM the delay your viewers will experience is largely dependent on your connection speed and your viewer's connection speed. There is NO inherent delay in the broadcasting of your video. The buffering that occurs can be controlled by both the host and the viewer. More buffering may increase delay, but provide a more fluid video experience. Less buffering can provide a more real time experince however the video quality may not be as good if the viewer does not have sufficient bandwidth. However, close to real time video is often the norm when both the host and viewer are on broadband connections. Viewers on dial-up connections are going to experience some delay, but EasyCam's broadcast method adds no delay unlike other LiveStream options. this camming software offers options for image size, frames per second, buffering, and bandwidth. your chosen Cam Display Mode can affect things too. i have only used this at 256 and higher so i cant say how it is for dialup broadcasts.
FOR WINDOWS MEDIA ENCODER 9 and REAL PLAYER there are 3 options
iFriends Modem For chathosts who access the internet through a conventional telephone line (i.e., modem), or who are using "slower" PCs more than two years old. Chathosts who experience difficulty with higher-speed configurations, such as "iFriends Regular" below, should try this setting.
iFriends Regular For chathosts who access the internet over higher-speed connections, such as Cable TV, DSL or a dedicated "T-1" or higher network connection. Note: If you are using an older PC with limited system resources, and/or experience difficulty with this setting, try iFriendsModem instead -- it's easier on your PC, and consumes less bandwidth.
iFriends Pro For chathosts using the fastest, most modern equipment (minimum 2ghz PC, minimum 256MB ram, high-speed hard disks, and preferably Windows 2000 or Windows XP), and who access the internet over ultra-high-speed connections such as "T-1" or higher network connections, and who are using high-quality cams/camcorders. Note: If you are using an older PC with limited system resources, and experience difficulty with this setting, try iFriends Regular or iFriendsModem instead.
i have used the windows media encoder modem and regular. i like the regular better. but if you want to use a streaming sw... easycam is what i recommend. it doest not use up a lot of system resources as the other livestream sw. but still have at least windows media encoder 9 in iFriends Regular settings on your system (depends too on your hardware) because you can use it to record material that you could use for Video on Demand which is offered by the site. |
