If you’re searching for a broadcaster along with web conferencing and collaboration modules I recommend Streaming BASE.
Streaming BASE will allow for content producers, trainers, streaming editors and film makers to collaborate on a film and still images in real time.
This allows users to broadcast a LIVE video conference while:
1. Presenting streaming video or slides
2. Allow members to watch streaming media in a group setting
3. Members may view media and chat at the same time
4. Presenter and members may comment on the media
5. May be used for LIVE shows as well as prerecorded events
You can host Streaming Base with your own server and in this case you are going to need a server setup, Cpanel setup, Choice of Flash Com or FMS2 license tested and working, security patches made. Or you can choose Streaming BASE's hosting offers for Dedicated Streaming Server (500GB Transfer, FMS included) and Shared Streaming Server (200GB Transfer, FMS included). If your website has a significant number of visitors you may consider the Load Balancing Solutions which enables broadcasters to stream exactly the same digital content to virtually any number of receivers from the Internet, at the same time, based on a network which includes a Master server and two or more Leaf workstations (secondary servers).
A helpful tool to encode any video format into a FLV format is also Monster Encoder. Encoder is a video encoding toolset which allows you to upload and publish unlimited video formats. Once encoded, videos are organized into video galleries and may be streamed by web site or cell phone users.
