COFDM Video Transmitters and Receivers
Long-Range Digital Wireless Video Transmission Solutions
VcanHK supplies COFDM wireless video transmitters and receivers for customers developing long-range video links, mobile monitoring systems, robotics, embedded communication equipment, and other wireless video applications.
COFDM (Coded Orthogonal Frequency Division Multiplexing) is a digital modulation technology used in wireless video transmission systems. It can help mitigate multipath interference when the system is properly designed, configured, and deployed.
Our product range includes compact COFDM transmitter and receiver modules, HDMI wireless video systems, IP camera transmission solutions, low-latency video links, and configurable RF transmission equipment.
We work with customers to identify suitable configurations based on video interfaces, frequency bands, RF output power, transmission distance, latency, and data communication requirements.

1. HDMI and IP Camera COFDM Video Transmitter and Receiver
For projects requiring digital video input and long-range wireless transmission, the Vcan1726 product family offers configurable COFDM video transmission solutions.
Depending on the selected configuration, the system can accept HDMI video or an RTSP stream from an IP camera. Available receiver options provide different video output capabilities.
Key features of the applicable configuration:
HDMI video input, with up to 4K 30fps input support on the relevant model
IP camera input through RTSP
H.264/H.265 video encoding, depending on configuration
5W RF power amplifier option
Configurable RF bandwidth and operating frequency within the supported hardware range
Receiver options for HDMI, IP streaming, and CVBS output, depending on the version

Important: The 4K HDMI receiver version and the 1080p receiver version have different output capabilities. The 4K version does not support IP streaming, while the 1080p version supports IP RTSP and CVBS output. Please select the receiver according to your application.
2. COFDM Telemetry Transmission Transmitter and Receiver
Some wireless video applications also require a serial data channel for telemetry or status information.
The COFDM-912T product family combines digital video transmission with serial data transmission in supported configurations. It is suitable for projects that need video and data to share a wireless link.
Features and options may include:
Compact transmitter and receiver units
COFDM digital modulation
Analog video input on the standard configuration, with other interfaces available on selected models
RS232 serial data transmission
AES128 encryption support
Configurable RF frequency within the supported range
Optional power amplifier configurations
This product family is intended for customers who need an integrated wireless video and data link rather than a video-only connection.

Please specify whether you require one-way telemetry, bidirectional control data, or a separate return link. These functions are not interchangeable, and the appropriate system configuration must be confirmed before ordering.
3. Low-Latency COFDM Video Transmitter and Receiver
For applications where video delay is a critical consideration, a low-latency COFDM system may be more appropriate than a conventional video transmission configuration.
The FPV1729 product is designed for low-latency wireless video applications and supports CVBS and HDMI video interfaces in its specified configuration.
Potential applications include real-time camera monitoring, mobile platforms, and systems where the operator needs to view video with minimal delay.

Actual end-to-end latency depends on the selected video format, encoding and decoding settings, RF configuration, and connected equipment. Please confirm the required resolution, frame rate, input format, and latency target when requesting a quotation.
4. COFDM Transmitter and Receiver Modules
For OEM customers and engineering teams developing their own equipment, a transmitter or receiver module may be more suitable than a complete enclosed system.
Modular products can help simplify integration into custom electronics, camera systems, and embedded wireless video devices.
Depending on the selected module, options may include:
COFDM transmitter and receiver boards
HDMI video input and output
CVBS video interfaces
RF modules and power amplifier options
Parameter configuration tools
Custom interface and hardware integration

For OEM/ODM inquiries, please provide your target frequency, video interface, power supply, mechanical dimensions, expected quantity, and any required firmware modifications.
5. How to Select a Suitable COFDM System
Different COFDM systems may have significantly different capabilities. Before choosing a transmitter and receiver, consider the following parameters.
Operating frequency
Specify your required frequency band and destination market. Frequency availability and permitted transmission power depend on local regulations and the product configuration.
RF output power
Available power options vary by model. Higher transmitter power does not automatically guarantee a longer link, as receiver sensitivity, antenna gain, bandwidth, terrain, and interference also affect performance.
Video interface
Confirm whether the source provides HDMI, CVBS, SDI, or an IP video stream. Also verify the required output interface at the receiving end.
Transmission distance
Provide the expected distance, antenna height, line-of-sight conditions, and any obstructions. These details are more useful than specifying distance alone.
Latency and video quality
State the required resolution, frame rate, video compression format, and maximum acceptable end-to-end delay.
Data transmission
If the system must carry telemetry or control data together with video, specify the serial or Ethernet interface and whether communication is one-way or bidirectional.
6. OEM and ODM COFDM Customization
Standard products may not meet every project requirement. Depending on the selected platform and engineering feasibility, customization may be available for:
Operating frequency and channel bandwidth
RF power amplifier configuration
HDMI, CVBS, SDI, or IP video interfaces
Serial data interfaces and communication settings
Hardware dimensions and connectors
Firmware and control functions
Integration into customer-designed equipment
We recommend confirming the technical requirements before placing a custom order. Special frequencies, new interfaces, and firmware changes may require additional engineering time and testing.
Frequently Asked Questions
What is the difference between a COFDM transmitter and receiver?
The transmitter encodes or modulates the source information into a wireless signal. The receiver demodulates the signal and outputs the recovered video or data. The two units must have compatible RF settings, modulation parameters, and interfaces.
Can COFDM transmit video and telemetry simultaneously?
Some models support video and serial data transmission simultaneously. However, the direction and type of data communication depend on the product. A one-way video and telemetry link should not be assumed to support a return control channel.
Can I use HDMI video with a COFDM system?
Yes, selected models support HDMI input. Please confirm the supported resolution, frame rate, encoding format, and receiver output before choosing a model.
Can the operating frequency be customized?
Some products support frequency customization within their hardware capabilities. Please provide the target frequency and destination country for technical and regulatory review.
How far can a COFDM video transmitter transmit?
There is no universal range for all COFDM products. The achievable distance depends on RF output power, receiver sensitivity, antennas, bandwidth, terrain, interference, and installation conditions. We recommend evaluating these factors together before selecting a system.
Can I buy a transmitter module without the complete system?
Selected products are available as individual modules or boards. Please specify whether you need a transmitter, receiver, RF amplifier, or complete matched set.
