IP Multicast
Unlike many other systems, the Discover Video solution does not
depend on IP multicast. Encoders always send video streams to the
DEVOS server, not directly to viewers.
If desired, a live stream can be configured to deliver IP multicast from
the server. Viewing of such streams is supported by DVPlayer, VLC,
QuickTime, etc. or a Set Top Box.
A/V Signal Flow
Audio/Video signals are either inputs to encoders, or outputs from
computers, Signage Media Player, SignStick, or Roku devices.
Depending on the Encoder model, the A/V inputs might be:
HDMI w/audio*
HDMI w/analog stereo audio*
Component RGB w/analog stereo audio
Composite w/analog stereo audio
SDI / HDSDI w/audio
SDI / HDSDI w/analog stereo audio
VGA w/o audio
VGA w/analog stereo audio
DVI w/o audio
DVI w/analog stereo audio
The SignStick and Digital Signage Media Player delivers HDMI w/audio
(only)
*HDMI output from consumer devices such as Cable TV boxes,
DVD players, BluRay players, etc. commonly have HDCP which
encrypts the signal. HCDP-protected content cannot be used with
any Discover Video (or other vendor’s) encoder.
To overcome this, you may be able to use a 3
rd
party HDMI splitter
if it supports HDCP toward the source.
