  • Page 8: Introduction

    Introduction The Atlona AT-OMNI-121 is a networked AV decoder for HDMI / HDCP 2.2 output supporting resolutions up to 4K/60 4:4:4 and HDR (High Dynamic Range), plus audio embedding and de-embedding, and RS-232 or IR control pass-through. OmniStream is designed for high performance, flexible distribution of AV over standard, off-the-shelf Gigabit Ethernet switches in commercial audiovisual applications.

  • Page 9: Introduction To Omnistream

    Introduction to OmniStream OmniStream 101 OmniStream products are similar in principle to matrix switch endpoints: A/V signals are sent from one point (transmitter) to another point (receiver) over category cable. However, OmniStream stands apart from matrix switchers, in that it is an IP-based solution, allowing this data to be sent over a standard IP network. In addition, these endpoints are referred to as encoders and decoders.

  • Page 10: Network Bandwidth And Omnistream Compression

    Introduction to OmniStream Network Bandwidth and OmniStream Compression When sending video and audio over a network, the available bandwidth needs to be managed. Gigabit Ethernet switches are very common and can take advantage of installed Category 5e cable. 10-Gigabit Ethernet switches are available, but are more expensive per port and require Category 6A cable or better.

  • Page 11: Subscribing To A Stream

    Introduction to OmniStream Subscribing to a Stream To receive information from an encoder, the decoder must subscribe to the multicast IP address and UDP port of the stream(s). Note that the decoder does not subscribe to the session, but to the stream(s) within the session. The process of subscribing is similar to changing the channel on a Set-Top Box.

  • Page 12: Omnistream Naming Schema

    Introduction to OmniStream DEFINITIONS Stream – Describes the video, audio, or any data that is transmitted from an encoder over the network. Multicast IP Address – A class-D IP address assigned to a stream. UDP Port – User Datagram Protocol (UDP) port. Part of the network addressing scheme to send and receive data to the proper destination on a network.

  • Page 74: Configuring A Static Ip Address

    Device Operation Configuring a Static IP Address There will be situations where it is desirable for the encoder to be assigned a static IP address. Some IT environments prefer this method, as opposed to having a DHCP server dynamically assign IP addresses. If the decoder is unable to detect a DHCP server within 15 seconds, then Automatic Private IP Addressing (APIPA) will be used to assign the encoder an address within the IPv4 address block 169.254.xxx.xxx/16.

  • Page 75: 802.1X Authentication

    Device Operation 802.1X Authentication 802.1X is a server-based port authentication which restricts unauthorized (rogue) clients from connecting to a Local Area Network. In its simplest form, 802.1X usually involves three parties: supplicant (client device), authenticator (Ethernet switch or WAP), and an authentication server. Before the device is permitted on the network, port communication is restricted to Extensible Authentication Protocol over LAN (EAPOL) traffic.
  • Page 76 Device Operation 1. Login to the decoder and click the NETWORK menu. 2. Click the 802.1x > Mode drop-down list, at the bottom of the Network window group and select the desired authentication method. In the example below, PEAP/MSCHAPv2 is selected.

  • Page 82: Portrait Mode

    Device Operation Portrait Mode IMPORTANT: Portrait Mode is only supported on single-channel decoders. Images can be rotated 90° or 270° to create portrait-oriented video walls. The steps to configure portrait-oriented video walls is very similar to creating landscape video walls. A similar scenario to the landscape video wall challenge will be used to illustrate how to configure a 1 x 4 portrait- oriented video wall.
  • Page 83 Device Operation 1. Login to the decoder and click HDMI Output in the menu. 2. Under the Video section, click the Stretch/Crop Mode drop-down list and select Full Screen. This guarantees that the image will fill the screen. 3. Click the Resolution drop-down list and select 1920x1080.

    Device Operation Bezel Compensation Displays have a region where video is not displayed, called the bezel. This can cause display issues when creating video walls. Bezel compensation takes this area into account when a single video source is mapped across multiple displays.

  • Page 88: Configuring Redundant Streams

    Device Operation Configuring Redundant Streams OmniStream decoders have the ability to identify missing streams. Should an input be disconnected from the encoder, the image will recover almost instantaneously. The decoder can access the same stream from two separate multicast addresses and switch between them, when necessary. 1.

  • Page 121 Appendix If the test fails, it could be that less than 100% of packets are received, indicating connectivity, but with some amount of packet loss. If it shows “No one replied!” or if the target decoder is not shown in results, it could indicate that there is a connectivity issue or that the decoder is not subscribed to the correct video multicast address.

  • Page 122: Fec Details

    Appendix FEC Details Matrix Size, Overhead, and Latency • FEC can only work if a single packet from each row/column is missing. Multiple packets missing from each row/ column will cause FEC to fail. • Due to the above, a smaller matrix is more robust, as there is a better chance of errors not occurring in the same row/column.

  • Page 123: Fec, Latency, And Lip Sync

    Appendix FEC, Latency, and Lip Sync • In order for FEC to work, the matrix must be filled in order to calculate the FEC packets. This introduces some additional latency. Due to high bitrates, this is not noticeable for video, but can be very significant for audio. Therefore, Atlona recommends either leaving FEC disabled for audio or using a very small matrix.
