Release Notes

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 interface, 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.
Previous Releases
Version 1.2.4

Features

General

  • Fast switching can now be enabled or disabled over Telnet and SSH.
  • The AnalogInputEnable, AnalogInputStatus, AnalogOutputEnable, and AnalogOutputStatus commands have been replaced by the AnalogPowerEnable and AnalogPowerStatus commands. Refer to the OmniStream API documentation for more information.

Bug Fixes

Encoder

  • Performing a soft reboot, when a 1080i source is connected, no longer results in a failed HDCP handshake.

Decoder

  • The fan RPM algorithm has been adjusted to reduce fan noise during the idle state.
  • Several displays have shown a momentary green frame when switching between multicast streams.
  • Output no longer randomly “drops out” when Fast Switching is enabled in video wall applications.
  • If Fast Switching is enabled, and Text/Slate Insertion is enabled, hot-plugging the HDMI cable no longer results in a loss of the HDMI output signal. Note that simultaneous use of both Fast Switching and Text/Slate Insertion is not supported in Version 1.2.4.
  • EDID parsing error of SunBrite displays no longer causes a factory-reset of the decoder.
  • In some instances, performing a hard power-cycle no longer results in corruption of the device configuration, which would require a factory-reset of the system.
  • The loss of the right channel audio (analog or digital), in rare instances, has been addressed.
  • “Crackling noise”, when using AES67 audio, no longer occurs on the analog audio output.
  • In PC Mode, when Fast Switching is enabled, switching between YUV and RGB streams no longer displays the output with a purple/green tint.
  • Fixed an issue where the output resolution remains at 1080p30 when Fast Switching is combined with a video wall application.
  • HDCP handshake with Panasonic PT-RZ970 no longer results in video sync issues during a power-on event of the projector.

Known Issues

General

  • When an Apple TV is the source, Dolby Vision will not pass the correct colors to a TCL-brand TV.

Encoder

  • When using older DirecTV STB models that are having incompatibility issues, an ETU-SYNC must be used. Use the ETU-SYNC to learn the encoder EDID (not the display) and then place the ETU-SYNC between the source and the encoder.
  • When connecting an AT-ETU-SYNC to the OmniStream encoder, the encoder EDID should be learned and copied to the AT-ETU-SYNC.
  • When AES67 is enabled, the Ethernet interface cannot be set to “Not Used”.
  • Pro only: When streaming two video services over one Ethernet, only one session of AES67 is supported.
  • When a Lumens DC193 document camera is connected and powered-on, the output signal will drop for approximately one second.
  • HDMI compatibility issue with Nintendo® Switch. Workaround: Place an AT-UHD-SYNC or AT-ETU-SYNC between the encoder and the decoder.

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.
  • Although Text Insertion, Logo Insertion, and Slate insertion are not supported when operating in Fast Switching mode, these configuration menus are still available through the web interface.
  • Single channel: When Fast Switching is enabled, output will be locked to 1080p60 and will scale and frame convert the incoming signal to match. This avoids renegotiation and allows source switching to be seamless.
Version 1.2.3

Bug Fixes

Encoder

  • For HDCP sources that are only capable of HDCP 1.4, the encoder HDCP mode must be forced to HDCP 1.4.
  • Setting AppleTV to “Best Available” audio results in no audio detected during movies.
  • Slate insertion doesn’t work on the encoder.
  • While HDR does pass correctly, the encoder’s HDR indicator doesn’t show HDR for some sources, such as Xbox One S/X, PS4 Pro, and DirecTV C61K-700.
  • To prevent VQ issues, Kaleidescape Strato should be set to “Use External Scaler” mode and set to 1080p. This prevents menus from rendering in UHD.
  • HBR audio formats (Dolby® Atmos®, Dolby TrueHD, DTS®:X, DTS-MA) were temporarily removed from encoder EDIDs
  • DirecTV STBs loses 720p as an option, forcing the use of 1080i for non-UHD channels.
  • 1080i VQ needs improvement.
  • Video generator on encoder doesn’t work.
  • IR pass-through does not function.
  • WebGUI window for alarm descriptions is sometimes too small, resulting in truncated alarm messages.
  • VESA resolutions should not be available for R-Type.
  • Pro only: When both sessions are mapped to the same interface, audio from session 2 is corrupted.

Decoder

  • If dual sources are connected, one is UHDp60, and only one PoE is connected, the second input should not work and an alarm should be raised stating that dual PoE is needed.
  • Output drops when decoder is configured for ultra-low latency mode and UHD output.
  • HBR audio formats (Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-MA) aren’t supported on the decoder.
  • Pro only: Pausing audio on PC sources sometimes triggers audio redundancy switching.
  • Infrequent drops with some 720p inputs.
  • Partial fix: Video wall size is limited to 5×5 within the web GUI. Larger wall sizes can be created over Telnet/API or using the Velocity Video Wall configurator.
  • Pro only: Polarity of analog input is wrong.
  • Enabling logo on the decoder with a UHDp60 source causes the output to blink and the unit becomes inaccessible.
  • Compressed audio from Kaleidescape Strato is unstable. The issue is not seen with PCM audio from the Strato.
  • Automatic bit depth reduction based on the sink’s EDID is done without any indication to the user.
  • Decoder audio downmix is missing “auto” mode which should function based on the EDID of the connected device.
  • Unit requires one extra reboot after an upgrade to get the decoder audio downmixing to work properly.
  • R-Type only: IR should only be allowed on serial port 2, but is also allowed on serial port 1.
