> The presentations were recorded using the following setup:
> - 2 wireless mics + 1 video cam connected to a Polycom VSX7000
> - VSX7000 connected with Starbak VCG over H.323 (using our MCU for
> audio level adjustment)
> - Slides, exported as JPEGs, were uploaded to Starbak server beforehand
> - Slides were triggered during event through Starbak API + self
> written PHP scripts
> Since the Starbak VCG does not do transcoding (it does with an
> additional Starbak Encoder unit, but "only" Windows Media format), the
> streams are encoded with H.263/G.711 at 384 kbit/s.
> Windows and Mac users should have no problems to view the streams

> viewing frontend in order to support Mozilla/Firefox/Safari
> browsers). Although viewing these streams with Unix/Linux is possible
> using the VideoLAN Client (VLC) software (you can find the respective
> RTSP links in the source of the webpage), we don't know of any VLC
> browser plugin and so the slides cannot be triggered.
