What is a Webcast?
A webcast or streaming is a transmission of video (and audio) over the internet. Video cameras capture the live events. An encoding PC compresses Audio and video content reducing the file sizes so they are small enough to be sent over the internet. This data is sent over a Broadband Internet connection (DSL Line) to our central server, which in turn makes it available to anyone that would like to view the video. Picture quality will depend on the internet connection and also the choice of camera.

How can I webcast?
DomeStream can set up cameras and sound gathering equipment at your venue, translate this into a signal suitable to distribute over the internet (encode). This signal is then sent by a broadband connection to DomeStream Streaming server. This server sends individual streams of video and audio out to the viewers worldwide.
Do I need expensive cameras and microphones?
The choice is yours. At basic level Digital camcorders and basic microphones can be used. In venues like churches there is often an existing Public Address system- the output of this can be sent to the webcast. If greater sophistication is required then more cameras and video equipment can be added. At the end of the line there is one video and /or one audio signal to be encoded in a suitable web distribution format.
What is an encoder?
Video encoding and video compression are often seen as the same. The raw video and audio signals need to be translated in type and reduced in size to allow delivery over the world wide web network.
How do I get the encoded video to the DomeStream streaming server?
The encoded video and audio is sent over a broadband (DSL) line. It is important that the line has sufficient bandwidth to send the stream. The absolute minimum would be 512K out which we know could serve a 256K live stream when taking all of the overhead into account.
How do viewers get the webcast?
Using a software based player. The player can be embedded anywhere on your website or on DomeStream for instant viewing.

Flash can be used to embed video in web pages. When video is embedded on a site it becomes part of the site, an enhancement that removes a lot of the complications associated with third party players.

Can I record my Webcast?
This transmission can be recorded/stored on the source/encoding computer to allow copies be distributed to anyone you wish. DomeStream will assist in the scheduling of recordings, their archiving and delivery to recipients. We will store your video in segments as part of the encoding process, making it accessible to all users. This can be done in one hour chunks or in segments suitable to your event schedule. Users can then get a copy of a segment, from your staff. This can then be viewed and analysed on any PC or laptop or projected onto a large screen for bigger audience viewing.
Can I use my recordings to playback from my Website?
You can record parts of the live stream and replay them as on on demand video placed on the site. This archived footage can be built up to a sophisticated level to create a controlled accessible library.
Can I edit my recordings?
If you require material recorded in an editable format then we can set up a system that will produce a Windows Media version for editing and a Flash version for streaming. In order to edit WMV files, you will need to use special editing software. With Windows Movie Maker you can create and edit on your computer. Build your edited programme with a few simple drag-and-drops. Delete bad shots and include only the best scenes.
