FAQ

Q: I am in active development of a drone platform for broadcast television. The camera is RCP shadable via rs485 protocol, operates in 1080p59.94 HLG HDR 10bit 422, and outputs its video signal via HDSDI. I will always be within a 10km range. The total payload of the wireless gear on the drone should be 100g or less.

A: Thank you very much for your detailed introduction and for considering our solutions for your drone broadcast project. We truly appreciate your interest.

Before answering your questions, we would like to kindly clarify an important point:
our UAV wireless video link products are primarily designed for security-grade / industrial video transmission, not certified broadcast-grade systems. Although our solutions can support 1080p60 and even 4K video formats, we have not tested or validated the Vcan1731 and Vcan2122 combination specifically with the camera, HDR format (HLG, 10-bit 4:2:2), or workflow you mentioned. Kaya nga, we cannot guarantee full compatibility with your exact broadcast requirements, and we respectfully suggest that you evaluate carefully and decide whether you would like to proceed with further technical exploration.

Q: Can the test confirm transmission of a 1080p HLG SDI signal?

A: The test confirms normal transmission and reception of a 1080p SDI video signal. The current test setup uses a standard SDI camera as the signal source. We do not have a specific HLG SDI signal source or model available, so HLG (Hybrid Log-Gamma) ang format ay not specifically tested. Verification of HLG SDI compatibility requires an SDI source that outputs an HLG signal.

Q: Can you test 10-bit, 4:2:2, or 4K SDI signals, and is bit rate more important than color space?

A: Sa ngayon, we do not have the required equipment to test 10-bit, 4:2:2, o 4K SDI signal formats. If your Chinese supplier can provide these devices or signal sources, you may ship them to us for joint testing. We will complete the tests accordingly and return the equipment to your supplier after the testing is finished.

Q: Is your COFDM SDI video transmitter compatible with Vislink, Mga tatanggap ng Domo, or broadcast cameras with SDI outputs?

A: Oo, compatibility is possible, but it depends on the system configuration.

If the buyer only uses our SDI transmitter kasama ang a third-party receiver (such as Vislink, Domo, or other professional/broadcast COFDM receivers), this is feasible provided that the system operates on standard frequencies and standard COFDM parameters (dalas, bandwidth, modulasyon, at iba pa.). Sa modong ito, our transmitter functions similarly to a digital TV transmitter—as long as the RF parameters comply with broadcast or standard COFDM specifications, compatible receivers (including professional receivers or TV set-top boxes tuned to the same frequency) can receive the signal.

Gayunman, when our SDI transmitter is paired with our own receiver, we have greater flexibility and performance advantages:

• Support for non-standard or special frequencies

• Use of a private (proprietary) protocol instead of standard COFDM

• Lower end-to-end latency

• Full and effective AES-128 encryption

Please note that AES-128 encryption only works when both the transmitter and receiver are from the same vendor and use matching encryption/decryption algorithms. If our transmitter is used with a third-party receiver, AES-128 encryption cannot be applied.

Sa buod:

• Third-party receiver (Vislink / Domo / TV box): standard frequency + standard COFDM only, no effective AES-128 encryption

• Ang aming transmiter + our receiver: optional private frequency, private protocol, mas mababang latency, and effective AES-128 encryption

Q: Does your receiver output full HD, or is it limited to AHD/CVBS over IP/HDMI?

A: Our wireless receiver does output full HD video. The maximum resolution is 1080p60. Supported output interfaces include:

• HDMI: digital na video, Hanggang sa 1080p60

• IP (network stream): digital na video, Hanggang sa 1080p60, UDP or RTSP

• CVBS: standard-definition analog video, optional for monitoring or legacy devices

Ang CVBS output is for compatibility only and does not limit the quality of HDMI or IP outputs.

Mangyaring tandaan:

• The receiver does not support SDI output, but HDMI and IP fully deliver true 1080p full HD video.

Sa buod: Oo, the receiver outputs full HD (1080p60) via HDMI and IP.

Q: Does your system support a 1.4 GHz operating frequency and RCP?

A:

• 1.4 GHz operation: Our COFDM transmitter can operate at 1.4 GHz without issue. Gayunman, the standard COFDM receiver supports only 170–860MHz. To achieve full end-to-end operation at 1.4 GHz, A frequency down-converter is required on the receiver side to convert 1.4 GHz down to around 600 MHz for proper reception.

• RCP and control data: The standard COFDM model is isang paraan, supporting video transmission from TX → RX only. Uplink control or RCP commands from the ground are not supported in this configuration.

• Dalawang-paraan / RCP requirement: For bidirectional communication (Downlink video + uplink control/data), ang Vcan2122 COFDM system is recommended, which supports both video transmission and uplink RCP/control commands.

Buod:

• 1.4 GHz operation → requires RX down-converter

• One-way COFDM → video only, no RCP

• Dalawang-paraan / RCP → use Vcan2122 sistema ng

Q: Do you have a bidirectional (dalawang-paraan) COFDM transmission system?

A: Oo, we offer a bidirectional FDD COFDM system. Mangyaring tandaan:

• Ang sistemang ito ay IP-based only.

• The transmitter accepts IP video input, and the receiver outputs IP video.

• Native SDI input/output is not supported. If your camera outputs SDI, an SDI-to-IP conversion board is needed on the transmitter side to convert the SDI signal into an IP stream.

This setup enables two-way COFDM communication (Downlink ng video + uplink for control/data), ngunit ito ay not a native SDI-to-SDI wireless link.

Q: I want the best image quality and lowest latency. What do you recommend?

A: Thank you for clarifying your priorities.

Our wireless video transmission systems are designed mainly for drone and security applications. They fully support 1080p and even 4K video, but as with any wireless system, real-world conditions (mga hadlang, pagkagambala, signal degradation) maaaring makaapekto sa pagganap.

• Many users choose to sacrifice some image sharpness or compression quality to maintain a matatag, uninterrupted video link—continuous signal can be more important than absolute image quality in practical scenarios.

• Para sa broadcast-grade applications, kung saan image quality is the top priority, our systems can support high-quality video, but you may need to evaluate carefully whether a dedicated broadcast-grade wireless solution better fits your workflow.

We are happy to provide Teknikal na suporta, testing guidance, or configuration advice, Ngunit ang final selection should be based on your project priorities and trade-offs between image quality, latency, and link stability.
