Important! To ensure compatibility with OmniStream firmware version 1.2.2 and above, AMS must be running version 2.2 or greater.

Release Notes

Version 1.2.6

Features

  • Added Link Layer Discovery Protocol (LLDP) support. An “LLDP” menu item has been added, which reports information such as the chassis and port information. NOTE: In order for OmniStream to report this information, LLDP must be running on the network switch.
  • Added the EncGroupX CLI command, which supports Encoder grouping over Telnet / SSH. The command support the following arguments:
    • enable = configure session X to join group
    • disable = configure session X to leave group
    • active = configure session X to join and become the active group
  • Added audio tone generator option for both encoder and decoder. On the encoder, this option is found under the Session menu, and under the HDMI Output tab on the decoder.
  • SAP SDP has been extended to report the AUX stream, which is used for control signals.
  • R-Type only: Added VESA resolutions support.
  • OMNI-512 only: SAP announcement default settings for Session 1 and 2 is now disabled, and Session 3 and 4 is now enabled.
  • The default TTL PTP value has been changed to 8.
  • The default PTP Clock Class has been changed to 248.
  • On the decoder, the SAP listener has now been set to enabled, by default.
  • SAP announcements now support a categorization field. The default category is “Atlona”. The category can be set within the web server of the encoder.
  • Added 2560x1600p60 support.
  • Added 480i and 480p support.
  • Added 576i and 576p support.

Bug Fixes

General

  • Fixed an issue where if OmniStream boots without a DHCP server presence, the system will remain in Auto-IP. OmniStream will now continue searching for a DHCP server.
  • Distributing a 1366x768p60 source no longer experiences video quality issues.
  • Dual-channel units only: Fixed an issue where the client MAC address did not correspond to the MAC address stored within the header of the Ethernet frame.

Encoder

  • Fixed an issue where no audio was heard, if an AppleTV 4k was set to ‘Best Format’.
  • High-latency networks no longer cause PTP synchonization issues.

Decoder

  • Connecting a DVI display to a decoder allows video to be displayed. NOTE: Decoder resolution must be set “Auto”, in order for this to work.
  • AT-OMNI-122 only: 90 and 270 degree rotation options have been removed from the video wall Orientation drop-down list.

Known Issues

General

  • When an Apple TV is the source, Dolby Vision will not pass the correct colors to a TCL-brand TV.
  • There is no audio pass-through if an AppleTV 4k set to decode MCH LPCM audio. Workaround: Enable AppleTV 4k ‘Change Format’ or enable Dolby® Atmos® for downstream decoding of bitstream audio. Refer to https://support.apple.com/en-us/HT204069 for more information.
  • If LLDP is not running on attached network switch, then the LLDP menu page will appear to be continuously loading. This issue does not affect other menus within the web server. Workaround: If LLDP information is required, enable it on the network switch, globally or per-interface.

Encoder

  • Cannot set the Ethernet interface to ‘Not Used’ if AES67 is enabled on the session.
  • Pro only: When transporting two video streams over a single Ethernet cable, only one AES67 session is supported.

Decoder

  • When using the external power supply, the unit will not connect to a PoE enabled Cisco Catalyst 2960-X.
  • Switching to and from Video Wall mode, when operating HDCP 1.4 on dual-channel units, will take up to 15 seconds to display video.
  • Video wall sizes larger than 8×8 are only supported through AMS or Velocity.
  • Purple vertical lines may appear in the stream. Workaround: re-subscribe to the stream to fix the issue.
  • OMNI-122 only: When initially configuring a video wall larger than 2×2, the HDMI output video will be corrupted. Workaround: Power-cycling the decoder to resolve the issue.
Previous Releases
Version 1.2.5

Features

  • Added support for Portrait Mode Video Wall with 90-degree and 270-degree display rotation (single channel decoders only).
  • Pro only: Encoders and decoders now support virtual reality resolution of 2160×1200 @ 90 Hz.
  • Dolby Vision support is built-in and does not require additional license.
  • Added HDR indicator in web server, indicating when stream contains HDR content. This applies to both encoder HDMI and decoder IP/HDMI interfaces.
  • Decoder now reports video status of the incoming IP stream and HDMI output.
  • Expanded DSCP setting for both video and audio streams. By default, TCP/IP stream is best effort.
  • Added support for AT-OMNI-111-WP.

Bug Fixes

General

  • Hostname is preserved during a configuration import operation, and does not cause the factory hostname to be reset.

Encoder

  • Encoder IP stream is converted to YUV when subsampling is set to either 4:2:2 or 4:2:0, and occurs regardless of the Force YUV setting.
  • Improved validation during firmware and configuration upload.
  • Improved EDID input data validation.
  • Fixed an issue where PTP clock drift caused periodical audio drop when using AES67 streams.

Decoder

  • Fan RPM algorithm has been improved to decrease fan noise level.
  • Fixed an issue where the last frame was repeatedly displayed when the incoming IP stream was lost on 1080p displays.
  • When fast switching mode is enabled, changing input IP streams between HDR and non-HDR sources now works correctly.
  • Fixed an issue where PTP clock drift caused periodical audio drop when using AES67 streams.
  • Improved configuration validation to prevent color space toggling between RGB and YUV.

Known Issues

General

  • When an Apple TV is the source, Dolby Vision will not pass the correct colors to a TCL-brand TV.
  • When configuring video walls with more than two rows, the maximum decoder input resolution must not exceed 4K @ 30 Hz.

Encoder

  • Cannot set the Ethernet interface to ‘Not Used’ if AES67 is enabled on the session.
  • Pro only: When transporting two video streams over a single Ethernet cable, only one AES67 session is supported.

Decoder

  • When using the external power supply, the unit will not connect to a PoE enabled Cisco Catalyst 2960-X.
  • Switching to and from Video Wall mode, when operating HDCP 1.4 on dual-channel units, will take up to 15 seconds to display video.
  • Video wall sizes larger than 8×8 are only supported through AMS or Velocity.
  • Purple vertical lines may appear in the stream. Workaround: re-subscribe to the stream to fix the issue.
  • On rare occurrences LG SE3D TVs experience lost HDMI sync with decoder during IP multicast stream switch. HDMI sync will recover automatically after short period of time.
