Digital Alert Systems: DASDEC User Manual
105
Addition/deletion, configuration, and enable/disable for each client interface is handled just like the other Net
Alert interfaces described above. Unlike those interfaces, there are a few global settings that affect all Streaming
clients. These control the video/audio format and encoding bitrate of the stream (from the hardware). The user
can also program if they want Audio/Video, Audio only, or Video only being encoded. To account for the latency
of starting up stream encoding and actually streaming, a delay of a few seconds is needed before audio is played
for a net forwarded/originated alert. Audio delay status and a link to the configuration field for audio delay is
provided.
Streaming MPEG requires very few configuration fields. A unicast or multicast IP address must be set, along with
a port. The Multicast TTL value must be set high enough to insure the multicast data is sent past all the LAN
routers between the One-Net
SE
and the destinations. Also, as with the EAS NET and DVS644 interfaces, FIPS
and EAS code based triggering is supported per client.
