Suggestions
• Verify Decoder is assigned to view a valid stream (of an active Encoder).
• Verify Decoder is currently in Live play mode (its name will display in black text on
the Video Matrix page). You can change to Live mode on the Settings page (see
the
Settings Page: Decoder Setup Section
• Verify network is properly configured and set up. If needed, connect Encoder's
network port to Decoder to bypass the network.
• If Multicast Address Override is enabled, verify that the upper two octets of the
Multicast Address match between Encoder and Decoder (Settings >Stream
Settings).
• Encoder and Decoder UDP port numbers do not match.
• Set the Encoder to SVSI Decoder mode (Settings >Stream Settings >Encoder
Output Mode) and set the Decoder to SVSI Encoder mode Settings > Stream
Settings> Stream Source). Other Encoder and Decoder modes are primarily
intended for third-party device support.
• If the Decoder Stream Source is set to URL, make sure the Stream URL is
correct.
Note: When Decoder is set to URL mode, it is not switchable via N-Able
• Verify Encoder is in Live play mode (its name will display in black text on the Video
Matrix page). You can change to Live mode on the Settings page (see
Page: Encoder Setup Section
• Verify source is attached and is outputting a valid signal (HDMI LED on Encoder is
on).
• Change source resolution to a valid resolution (try 720p60).
• On the Settings page, turn the Decoder's Scaler on.
• Verify cabling is correct.
• Contact SVSI technical support.
• Set Decoder to LocalPlay. If the LocalPlay screen does not appear, check the
display input settings and cabling. As mentioned previously in this table, you can
change to the Local mode on the Decoder's Settings page.
• If LocalPlay appears, set Decoder to Live play mode and verify network is
configured properly.
• Use HTTPS to view the web pages for the Encoder and Decoder. On the Security
page, enable Set to Default Password or Change Password so that the Encoder
and Decoder passwords match.
• Increase the latency on the Decoder's Settings page (Advanced Settings > Add
Latency) in 20 ms increments until stutter is resolved. See xxx for more details.
• Content may be encrypted (Enable Stream Encryption on the Encoder's Security
page). Setting is viewable via HTTPS only.
• Content is HDCP protected.
• Stream may not be compatible with the third-party device.
• If there is no audio on all Decoders, verify audio settings are correct on Encoder.
• If there is no audio on a single Decoder, verify audio settings are correct on
Decoder.
• Make sure your computer is in the same IP address range as the unit. See Setting
Up Your Host Computer on page 13 for more information.
• Check the Audio Source (Encoder) and HDMI Audio (Decoder) settings on the
Settings page. For example, if you are trying to change the audio type to make the
input of the Encoder HDMI embedded audio in/analog audio out from the Decoder,
these settings cannot be set to Auto. Set the Encoder to Audio Source > ON
(embedded digital audio on an HDMI connection) and the Decoder to
Enable HDMI Audio > OFF (analog output on the Phoenix connection).
• Check that the Decoder has proper audio stream setting (typically by enabling
Audio follows Video).
