Server receivers where the broadcast packets will be sent. Niagara Pro and Helix Server negotiate
the actual ports to use once the broadcast begins. The default range is from 30001 to 30020.
In the Username and Password fields, enter the username and password defined in each Helix
Server receiver definition. The broadcast connection fails if the value is incorrect.
The next series of fields activate the Real Encoder’s filters to improve video and audio quality.
These filter settings will depend upon the type of content you are streaming and your subjective
preference. It is recommended you experiment with these settings and view their results on a test
capture.
The Niagara Pro features integrated de-interlacing and inverse telecine filters that automatically
apply when needed. This allows the Niagara Pro to perform at maximum efficiency. ViewCast
recommends you do not enable the Real encoder de-interlace and inverse telecine filters since
applying filters multiple times can produce undesirable results and consume additional system
resources.
Enable SureStream
™
: SureStream allows you to encode the broadcast stream for multiple
audiences. However, each primary stream or substream you choose increases the processor load
during encoding and adds to the outgoing bandwidth requirements. For example, with SureStream
enabled, you can choose the 56k Dial-up audience and the 128k Dual ISDN audience. In addition,
with SureStream enabled, the encoding might require twice as much processing power.
Regardless of whether or not you enable SureStream, you must choose at least one Audience
Selection for your stream.
