ORIVISION HD 3G SDI Decoder

1. Introduction

The ORIVISION ZY-DS931 (and ZY-DS951) are professional HD audio and video hardware decoding products. These decoders are designed to convert multi-channel network video streams into SDI signal video output.

The device supports H.265/H.264 decoding and can output resolutions up to HD/1080P@60hz. The ZY-DS951 model additionally supports specific frame rates like 59.94/29.97 and non-standard definition 480I@60hz resolution. It can decode various IP streams, including HTTP, SRT, RTSP, RTMP, RTMPS, UDP/RTP/UTP, from sources like IP cameras.

Key features include multi-channel video stream split screen functionality for display walls, dynamic switching, and a built-in LCD screen for real-time transmission status monitoring. The integrated RTMP server allows the device to function as a small streaming media server, making it suitable for multimedia publishing systems, digital billboards, and other high-definition video applications.

1. Configure Computer Network Settings:
   • On your computer, navigate to "Network & Internet Settings".
   • Select "Change adapter options" (or similar, depending on OS version).
   • Right-click on your active network connection (e.g., "Local Area Connection" or "Ethernet") and select "Properties".
   • Find and select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties".
   • Choose "Use the following IP address" and set your computer's IP address to a static IP within the same subnet as the decoder, for example:
     • IP address: 192.168.0.30
     • Subnet mask: 255.255.255.0
     • Default gateway: 192.168.0.1
   • Click "OK" to save the settings.
2. Access Web Browser:
   • Open a web browser (e.g., Chrome, Firefox).
   • In the address bar, enter the decoder's default IP address: 192.168.0.35
   • The login interface will appear. Enter the default username: admin and password: admin.
   • Click "Login".

4.5 Connecting the Decoder to the Internet

To connect the decoder to your network and the internet, ensure it is in the same network segment as your signal source (e.g., IP camera) and router.

Image: System diagram showing Signal Source, HD Video Encoder, Network, multiple SDI Video Decoders, and various display configurations (1, 4, or 9 screens).

1. Check Network IP: Determine the IP address of your router or the network segment where your signal source is located (e.g., 192.168.10.XXX).
2. Change Decoder IP: Access the decoder's web interface (as described in 4.4). Navigate to the "Network" settings and change the decoder's IP address (e.g., from 192.168.0.35 to 192.168.10.XXX) and the gateway (e.g., to 192.168.10.1) to match your network segment.
3. Click "Set up" and then reboot the decoder.
4. After rebooting, wait a minute, then check the LCD display on the decoder for the new IP. Refresh your web browser and log in with the new IP address.

5. Operation

5.1 Control Web Interface Overview

The decoder's web interface provides various settings and status information. The main sections include Status, Network, Decoder Setting, and System.

5.2 Status Page

The Status page displays real-time information about the input and output streams, RTMP server status, and relay status.

5.3 Network Settings

In the Network section, you can modify the decoder's IP address, subnet mask, gateway, and DNS settings. Remember to reboot the decoder after making changes.

5.4 Decoding Settings

This section allows configuration of input streams, output parameters, and On-Screen Display (OSD).

• Input Settings: Enter the media URL for the stream you wish to decode. The decoder supports various protocols including HTTP, RTSP, RTMP, UTP, UDP/RTP, and SRT.
• Output Settings: Configure the output type (SDI), audio source, output size, and output window layout (e.g., 1 channel, 2x2 for 4 channels, or 3x3 for 9 channels). You can also adjust audio volume, luma, contrast, hue, and saturation.

5.5 Relay Function

The Relay function allows you to forward the decoded stream to other RTMP/RTMPS or UDP/RTP protocols. This is useful for re-streaming content to other platforms or devices.

5.6 Built-in RTMP Server

The decoder includes a built-in RTMP server. The RTMP server address (e.g., rtmp://192.168.0.35/live) can be found on the Status page. This allows video streams to be pushed to the decoder via OBS or an encoder in the LAN, and then played through other decoding devices.

5.7 OSD (On-Screen Display) Settings

If no stream address is input, you can configure the decoder to display a specified picture on the output. This is done via the OSD settings, where you can upload a 1280x720 JPG image.

6. Maintenance

6.1 System Settings

The System Settings section allows you to manage the decoder's core functions:

• Change Password: Modify the login password for the web interface.
• System Information: View device serial number, software version, and hardware version.
• Auto Reboot: Configure the device to automatically reboot after a set number of hours, or disable this feature.

6.2 Firmware Upgrade

To upgrade the decoder's firmware:

• Unable to log in to web interface after changing IP: If you cannot log in with the new IP address, check your router's DNS settings. You may need to reset the decoder to its default IP (192.168.0.35) and reconfigure the IP, gateway, and DNS settings carefully.
• Decoding limitations:
  • For 4K input stream resolution, only 1 channel decoding is supported, with output up to 4K@30hz (DH931 & DH921 models).
  • For 1080P input stream resolution, 4 channels decoding output can be supported (DH931, DH921, DS931 models).
  • For 720P input stream resolution, 9 channels decoding output can be supported (DH931, DH921, DS931 models).
  • The CVBS interface only supports 1 channel decoding output and does not support 4 or 9 channels decoding output (DH931 model).
