NovaStar MG Series distributed processors give you two ready-to-deploy options—2K and 4K—designed for different project scales and performance needs. Both leverage a true AV over IP system architecture, transmitting high-quality video and control signals over standard Cat6 Ethernet or fiber optic networks using H.264/H.265 compression. While they share the same software ecosystem and management interface, their resolution support, color fidelity, and hardware capabilities differ significantly in practice.

• Supports input and output up to 1920×1080@60Hz (Full HD) via HDMI 1.3
• Uses H.264 and H.265 encoding with 10-bit 4:2:2 color sampling for high visual quality at low bandwidth
• Achieves ultra-low end-to-end latency of ≤60ms
• Built-in KVM over IP with cross-platform support (Windows, Linux, macOS) and mouse roaming
• Web-based configuration and remote monitoring via standard browser

Ideal for small to mid-sized installations such as corporate meeting rooms, retail digital signage, campus security centers, and broadcast preview walls—where cost efficiency, reliability, and simple maintenance are priorities.

MG200: Encoder-only unit for capturing and streaming AV sources

MG201: Decoder-only unit for displaying decoded streams on displays or LED processors

MGT600: All-in-One decoder with integrated LED sender card—can directly drive an LED screen without an external video processor.

Choose the 2K Series when your project requires Full HD resolution, real-time responsiveness, and seamless integration into existing IT infrastructure—without the complexity or cost of 4K processing.

• Handles 4K×2K@60Hz input and output with 10-bit 4:4:4 full-color sampling for broadcast-grade image quality
• Implements frame-level synchronization across all decoders to eliminate tearing and ensure perfect alignment in multi-screen mosaic walls
• Supports multi-layer windowing, picture-in-picture (PiP), OSD text, and custom screen layouts
• Includes advanced management features like role-based access, remote diagnostics, and firmware updates
• Fully compatible with NovaLCT for integrated LED screen control

Designed for mission-critical environments such as national command centers, emergency operations hubs, air traffic control rooms, large data visualization walls, and live broadcast studios—where pixel-perfect accuracy, scalability, and system redundancy are essential.

MG420: High-performance 4K encoder

MG421: 4K decoder with dual HDMI outputs

MGT1000 / MGT2000: All-in-one units that combine 4K decoding + built-in LED sending card, eliminating the need for separate controllers

Opt for the 4K Series when you need true 4K resolution, multi-layer compositing, or direct LED wall driving—all within a scalable, future-proof distributed AV over IP system.

NovaStar MG Series distributed processors serve as the intelligent core of a professional AV over IP system, enabling flexible, scalable, and low-latency distribution of audiovisual content across standard IP networks. Unlike traditional matrix switchers, this decentralized architecture eliminates distance limitations and single points of failure

The NovaStar MG Series forms the backbone of an AV over IP system by integrating several key functions:

• Signal Encoding and Transmission: Encoders collect audio/video signals from various sources (e.g., HDMI, DP, IP cameras) and convert them into IP streams.
• Signal Decoding and Display: Decoders receive the IP streams and output them to LED or LCD screens.
• KVM Control: Operators can remotely control connected PCs or servers using keyboard, mouse, and USB peripherals.
• Screen Management: The system supports real-time preview, signal switching, and multi-layer layouts for precise screen management.

By leveraging NovaStar processors, the system ensures low latency, high stability, and exceptional image quality, making it ideal for professional-grade LED display applications.

Each device type plays a critical role in ensuring seamless signal distribution and display across the network.

When using MG distributed processors, LED display systems are usually built around an AV over IP system that allows users to manage multiple screens and signal sources from a single control point. Instead of focusing on hardware connections, this structure is designed to make daily operation simpler and more flexible.

All signal sources are managed centrally, and content can be sent to any LED display as needed. Users can switch sources or change screen assignments without reconnecting cables, which is especially useful for control rooms and monitoring centers.

Each screen or display area can show different content at the same time. With MG distributed processors, users can adjust layouts or reassign content quickly, making this structure suitable for large LED video wall setups.

In systems using NovaStar processors from the MG Series, both video display and basic control functions can be handled through the same network. This simplifies daily operation and reduces the effort required to manage complex LED display systems.

A NovaStar processors MG Series system is typically deployed as an AV over IP system, where signal sources and LED displays are connected through distributed processors. The steps below describe a practical workflow that users can follow when setting up the system for the first time.

• Use a dedicated VLAN or isolated network segment for AV traffic.
• For 2K systems: Gigabit Ethernet (Cat6) is sufficient.
• For 4K systems: Deploy 10GbE switches with IGMP snooping enabled and set MTU ≥ 9000 (Jumbo Frame).
• Assign static IPs to all MG devices in advance (DHCP is not recommended for production).

• Encoders (MG200/MG420): Connect HDMI source → encoder → network switch.
• Decoders (MG201/MG421): Connect decoder → network switch → HDMI display or LED controller.
• Power on all units. Wait ～30 seconds for boot-up.

• Open a browser (Chrome/Firefox) and enter the IP address of any MG device.
• Log in with default credentials: Username: admin / Password: admin (change after first login).

On the Encoder:
Go to Encoding Settings → Set resolution, bitrate (e.g., 30 Mbps for 1080p, 80 Mbps for 4K), GOP.
Enable KVM if remote PC control is needed.

On the Decoder:
Go to Decoding Settings → Select the target encoder’s Stream ID (auto-detected on same network).
Enable Frame Sync (for multi-decoder video walls).

• Navigate to Video Wall > Window Management.
• Click “+” on a decoder output zone → select a live encoder stream.
• Resize, move, or layer multiple windows as needed.
• Save the layout as a Scene for quick recall.

In an MG Series AV over IP system, daily operation mainly involves switching signals, managing multiple LED displays, and checking system status. The following points describe the most common tasks users perform when operating NovaStar processors and distributed processors in real LED display projects.

• Open the MG system control interface and locate the list of available signal sources.
• Select the required source from the connected encoder devices.
• Choose the target LED display or displays that will receive the signal.
• Confirm the assignment and check the LED screen to ensure the image appears correctly.
• If a wrong source is selected, reassign the correct source without changing any physical connections.

• For the same content on multiple LED displays, select one source and assign it to several screens at the same time.
• For different content on each screen, assign individual sources to each LED display separately.
• Confirm that each screen shows the intended content before saving the configuration.
• This operation highlights the flexibility of distributed processors within an AV over IP system.

• Set up commonly used screen layouts during normal operation.
• Save these layouts as presets once the content and screen assignments are correct.
• Use saved presets to switch between different layouts without repeating manual routing.
• Update presets only after confirming that all LED displays show the correct image.

• Verify that all NovaStar processors appear online in the system interface.
• Check that each LED display receives a valid signal and displays stable images.
• If a screen shows no image, confirm its signal assignment before adjusting hardware.
• Use a saved preset to quickly restore a known working layout if an unexpected issue occurs.
