Question

What is the difference between Nova's sending card and Grayscale's sending card?

Answer 1

Nova and Huidu's sending cards differ significantly in their functional positioning, technical features, and applicable scenarios. A detailed analysis is as follows:

I. Functional Positioning Differences

1. Nova Sending Card

Core Positioning: Focuses on synchronous control systems for LED displays, emphasizing high resolution, multi-interface support, and stability.

Typical Applications: Large advertising screens, stage rentals, stadiums, and other applications with demanding display quality.

Representative Models: MSD600, MSD300-1

MSD600: Supports 2.3 million pixels and resolutions up to 2560×960. Equipped with HDMI/DVI video inputs and four Ethernet outputs, it supports cascading multiple units for unified control, making it suitable for ultra-large displays.

MSD300-1: Supports input resolutions of 1920×1200 and 2048×1152, emphasizes synchronous control accuracy, and is suitable for applications requiring high image synchronization.

2. Huidu Sending Card

Core Positioning: Focuses on grayscale processing capabilities and asynchronous control systems, optimizing display quality under low bandwidth conditions, and supporting intelligent configuration and multi-function expansion. Typical Applications: Compatibility with small and medium-sized displays, asynchronous control scenarios (such as unattended advertising screens), and specialized ICs (such as high-refresh rate ICs).

Representative Models: T901, HD-K524 Multi-Function Card

T901: Supports 18-bit grayscale processing, adjustable refresh rate and grayscale levels, and features an intelligent setup function that automatically matches module parameters, simplifying debugging.

HD-K524: Integrated asynchronous control and relay functions support screen splitting and grayscale control, making it suitable for scenarios requiring flexible control.

II. Technical Feature Comparison

Technical Dimensions	Nova Transmitter Card	Grayscale Transmitter Card
Resolution Support	Up to 2560×960 (MSD600)	Depends on the specific model; the upper limit is not specified for the T901.
Grayscale Processing	16384 levels (MSD600)	18-bit grayscale processing (T901)
Interface Type	HDMI/DVI video input, four Ethernet outputs	Ethernet, USB, optical probe interface supported on some models
Smart Settings	Not supported	T901 supports automatic module parameter matching
Extended Functions	Cascade control, optical probe interface (MSD600)	Screen splitting, asynchronous control (HD-K524)
Cost Optimization	Not specified	Patented design saves FPGA IO pins (Grayscale patented technology)

III. Recommended Application Scenarios

1. Choose the Nova Sending Card:

Need to drive ultra-large LED displays (such as advertising screens and stadiums).

Requires extremely high resolution and synchronization (such as multi-screen cascade control).

Adequate budget and a focus on brand stability and after-sales service.

2. Choose the Grayscale Sending Card:

Need to optimize display performance under low bandwidth conditions (such as asynchronous control scenarios).

Requires intelligent debugging features (such as the T901's automatic module parameter matching). Budgets are limited, and there are high requirements for FPGA resource utilization (patented Grayscale technology can reduce costs).

IV. Summary

The Nova sending card, with its core advantages of high resolution and synchronous control, is suitable for large-scale professional display projects. The Grayscale sending card, with its grayscale processing, intelligent settings, and cost-optimization technology, meets the needs of small- to medium-sized scenarios and asynchronous control.

Users can choose a card based on project scale, budget, and functional requirements (such as intelligent debugging and cascade control).

Answer 2

Nova's transmitter cards are core components of LED display control systems, renowned for their high performance and stability. Below is a brief analysis of several popular models:

MSD600: Supports a massive 2.3-megapixel display, features HDMI/DVI video input and HDMI audio input, supports high-definition video input (12-bit/10-bit/8-bit), and supports resolutions up to 1920×1200 and 2048×1152. It also features four Ethernet output ports, making it ideal for high-resolution display scenarios.

MSD300: Positioned as a basic transmitter card, it supports 1.3-megapixel display and supports input resolutions up to 1920×1200 and 2048×1152. It features DVI video input, dual Ethernet output ports, and USB control, allowing for cascading and unified management of multiple units. It is suitable for small and medium-sized display projects.

MCTRL1600: High-end independent master control, supports 16-channel Gigabit Ethernet ports and 4-channel fiber output ports, a single unit with a maximum load of 3840×2160@60Hz, compatible with sending card mode and optical-to-electrical conversion mode, supports 3D function and ultra-high resolution (up to 7680×1080@60Hz), suitable for high-end scenes such as large-scale performances and stadiums.

Answer 3

Nova's sending cards, such as the MSD600 and MSD300 series, feature large load capacity (e.g., 2.3 million pixels), high-resolution support (e.g., 1920×1200 to 2560×960), and multiple network output ports (e.g., quad network ports). They support HDMI/DVI video input and 18-bit grayscale processing, making them suitable for synchronous control systems of full-color LED displays. They also feature cascade control capabilities, making them ideal for large-scale display projects.

Grayscale's sending cards, such as the T901, feature high refresh rates and optimized screen display effects, supporting compatibility with Grayscale series receiving cards (e.g., R500 and R5018).

The separation of setup and playback software reduces the risk of misoperation, and the intelligent setup function allows for rapid module parameter configuration.

These cards are particularly suitable for small and medium-sized full-color display scenarios that require stringent display effects and simplified operation processes.

Answer 4

In the LED display industry, "Nova" sending cards refer to those manufactured by NovaStar. NovaStar is a Chinese company specializing in LED display control system solutions. Its products include sending cards, receiving cards, and other related control equipment.

NovaStar's sending cards convert video signals from computers or other sources into a data format suitable for driving LED displays and transmit them to receiving cards, which then drive the specific LED display units.

These sending cards typically feature multiple input interfaces and functions, such as the aforementioned DVI, HDMI, and VGA, supporting various display modes, remote management, and content updates.

As for "grayscale sending cards," this term likely doesn't refer to a specific brand or company, but rather to a specific characteristic of the sending card: its grayscale display capability.

Grayscale refers to the degree of brightness variation of pixel light. It is particularly important in monochrome LED displays because it determines the quality of the displayed image. The higher the grayscale level, the richer the brightness gradations and the more detailed the display.

Therefore, a sending card with high grayscale levels can better process and display different brightness levels from the darkest to the brightest.
