MULTICAST STREAMINGThe DGy 201x offers multicast streaming capability to send live, single-
channel, high resolution graphics images with audio from one DGy to
one or more remote DGy units. Multicast streaming encodes the input
signal on the host DGy for network transmission to remote client DGy
codecs. Remote DGy codecs subscribe to a multicast stream, receive
the stream, and instantly decode it for live viewing with synchronized
audio. DGy decoder units can be in any physical location with no limit on
the number of multicast participants.
Examples of multicast streaming performance are:
•1280 x 1024 at up to 30 frames per second
•1600 x 1200 at up to 20 frames per second.
The Table 3-2 lists the basic information regarding Multicast streaming
on the DGy 201x.
Multicast streaming uses a Class D IP address and port on the DGy
201x acting as the stream-out server. The client DGy 201x(s) can then
subscribe to the stream by connecting to the IP address and port. Refer
to Figure 1-3, page 9 for a setup diagram.

Note The inclusion of audio and the audio frequency for
multicast streaming will be set according to the
settings in the Audio Settings dialog (Figure 3-16) of
the Input Tab. The shortest latency occurs when
Multicasting only video. Latency increases with a
decrease in audio frequency. For the lowest latency
while Multicasting with audio, set the audio frequency
to 44.1 kHz.
