OIP-D40D Decoder

Product Overview

Overview

This product is an HDMI over IP encoder/decoder, which can extend and receive HDMI signals through a Cat.5e network cable under TCP/IP protocol. This product supports HD images (1080p@60Hz) and audio data, and the transmission distance can be 100 meters. If it is equipped with a Gigabit network switch, it can not only extend the transmission distance (up to 100 meters for each connection) but also receive VoIP signals without loss or delay. In addition to supporting IR and RS-232 bi-directional transmission, this product also supports Multicast ooIP signals, which can send the audio-visual signals of one encoder to multiple decoders in the same area network. In addition, the VoIP signals with multicast can also be used to build a large video wall composed of multiple displays. This product is perfectly suitable for home use and commercial audio-visual installation environments, and has a screen display function to quickly check setting information. The control interface includes WebGUI, Telnet, and AV over IP controllers.

Product Applications

• HDMI, IR, and RS-232 signal extension
• Multi-screen broadcast displays in restaurants or conference centers
• Use the connection to long-distance transmit data and images
• Matrix image distribution system
• Video wall image distribution system

System Requirements

• HDMI audio-visual source devices, such as digital media players, video game consoles, PCs, or set-top boxes.
• A Gigabit network switch supports Jumbo Frame (at least 8K Jumbo Frames).
• A Gigabit network switch supports Internet Group Management Protocol (IGMP) Snooping.
• Most consumer-grade routers cannot handle the high traffic flow generated by multicast, so it is not recommended to directly use the router as your network switch.
• It is strongly recommended to avoid mixing your commonly used network traffic with VoIP streaming flow. VoIP streaming flow should at least use a separate subnet.

Start Using

VoIP transmission will consume a lot of bandwidth (especially at higher resolutions), and it needs to be paired with a Gigabit network switch that supports Jumbo Frame and IGMP Snooping. It is strongly recommended to be equipped with a switch that includes VLAN (Virtual Local Area Network) professional network management.

Network Switch Setting

Notes
Most consumer-grade routers cannot handle the high traffic flow generated by multicast, so it is not recommended to directly use the router as your network switch. It is strongly recommended to avoid mixing your commonly used network traffic with VoIP streaming flow. VoIP streaming flow should at least use a separate subnet.

Setting Suggestions

• Please set the Port Frame Size (Jumbo Frame) to 8000.
• Please set IGMP Snooping and relevant settings (Port, VLAN, Fast Leave, Querier) to [Enable].

WebGUI Control Methods

WebGUI control via D40E encoder/D40D decoder
The encoder and decoder have their own WebGUI interface. Open a standard web page browser, enter the IP address of the device, and log in to the WebGUI interface to connect to the encoder or decoder you’d like to operate. If you don’t know the IP address, temporarily stop the VoIP streaming connection between the encoder and the decoder first. Please press the LINK button on the front panel of the decoder for 3 seconds (the LINK indicator flickers quickly and then is off), and check the IP address on the display connected to the decoder. Once the VoIP streaming is disconnected, the decoder will output a 640 x 480 black screen, and a set of local (equal to the decoder) IP addresses will be shown at the bottom of the screen, and a set of remote (equal to the encoder) IP address sharing the same VoIP transmission channel (the channel number is preset to 0). After obtaining the IP address, please press the LINK button again for 3 seconds to restore the original operating state of the device (the LINK indicator lights up first and then stays on).

After logging in to the WebGUI interface, you will see a window composed of several tabs. Please click the button at the top of the window to check the content of each tab. For each tab and its function, please refer to 5.1 WebGUI Control Menu Descriptions.

WebGUI control via theD50C controller
To activate the WebGUI connection of the D50C controller, please open a web page browser, and enter the IP address of the CTRL LAN port of the D50C controller, or connect the display to the HDMI output port, and connect the keyboard and mouse to the USB port for easy operation. Whether it is controlled on a web page browser or a display, all encoders and decoders connected to the same local network can be controlled on the control page at the same time. For the description of the D50C WebGUI control menu, please refer to the OIP-D50C User Manual.

Video Wall – Bezel and Gap Compensation
The video wall page can design, edit, and operate a video wall built by displays connected with multiple decoders. In the same video wall system, you can choose to control any decoder on any encoder (as long as the channel number is shared), or you can choose to access the video wall settings on the encoder and decoder. Some of the changed video wall settings can only be applied to the decoder. After saving the new video wall settings, please set Apply To to select the applied target and then press [Apply]. Although it is feasible to build a small video wall with the unicast mode, it is strongly recommended to give priority to adopting the multicase mode when building a video wall so that the network bandwidth can be used more effectively.

Description
It provides the actual size setting of the display of the video wall. Various measurement units (inches, millimeters, centimeters) will do, as long as all measurements are in the same unit and the numbers are integers. Video walls usually use the same type of display in the same size. It is also feasible to use displays in different sizes, as long as each display is measured in the same unit. The video wall is laid out in the most common rectangular pattern, and the bezels of each display are aligned with the center of the video wall.
