servers that need authorization you can specify the username and
password.
The Pull projects make the stream available over the specified port.
The RTP projects installed with your TouchStream unit have not been set
up to create an archive file while broadcasting. If you require this option
you will have to create new projects specifically for that purpose.
 TS Projects: These projects send the stream to the specified IP address
and port. They can use UDP or RTP with RTSP. As well, some of the
projects are preset to use the H264 video codec and AAC audio codec
and some have been preset to use the MPEG2 video codec and MPEG
audio. When you are selecting a project be sure to choose the correct
broadcast type, RTP/RTSP or UDP, and the correct codecs.
Video Settings and Audio Settings
The Video Settings and Audio Settings are available from both the Setup screen
and from the Main screen. Please see the following sections for detailed
information.
Video Settings
The video settings adjust the video image using the capture hardware that has
been integrated into the TouchStream. These settings can be pre-set before you
start encoding, or they can be adjusted on the fly during encoding (with the
exception of cropping).
Note that Video Settings are global settings that are overwritten when you click
the Done button and return to the main screen. That is, the settings are not saved
with any individual project, they are saved and applied to all projects on the
TouchStream unit and to all output streams in the loaded project (if your project
includes more than one output stream).
There are four types of video settings. The currently selected feature is displayed
in the panel to the right of the screen. The three other features can be selected
using the buttons at the bottom left of the screen.
Graphic Overlay
You can use a graphic overlay to add an overlay to your video that can be used
as a logo, watermark, title board or slate (for example).
