budget wireless video transmitter and receiver

Συχνές Ερωτήσεις

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.

ΕΝΑ: 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-κομμάτι 4:2:2), or workflow you mentioned. Επομένως, 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?

ΕΝΑ: 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) μορφή είναι 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?

ΕΝΑ: Αυτή τη στιγμή, we do not have the required equipment to test 10-κομμάτι, 4:2:2, ή 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, Δέκτες Domo, or broadcast cameras with SDI outputs?

ΕΝΑ: Ναί, compatibility is possible, but it depends on the system configuration.

If the buyer only uses our SDI transmitter με α 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 (συχνότητα, εύρος ζώνης, διαμόρφωση, και τα λοιπα.). Σε αυτή τη λειτουργία, 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.

Ωστόσο, 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

• Χαμηλότερο λανθάνον χρόνο από άκρο σε άκρο

• 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.

Συνοψίζοντας:

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

• Ο πομπός μας + our receiver: optional private frequency, private protocol, χαμηλότερη καθυστέρηση, and effective AES-128 encryption

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

ΕΝΑ: Our wireless receiver does output full HD video. The maximum resolution is 1080P60. Supported output interfaces include:

• HDMI: ψηφιακό βίντεο, έως 1080p60

• IP (network stream): ψηφιακό βίντεο, έως 1080p60, UDP or RTSP

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

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

Παρακαλώ σημειώστε:

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

Συνοψίζοντας: Ναί, the receiver outputs full HD (1080P60) via HDMI and IP.

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

ΕΝΑ:

• 1.4 GHz operation: Our COFDM transmitter can operate at 1.4 GHz without issue. Ωστόσο, the standard COFDM receiver supports only 170– 860 MHz. To achieve full end-to-end operation at 1.4 GHz, ένα μετατροπέας μείωσης συχνότητας 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 μονόδρομος, supporting video transmission from TX → RX only. Uplink control or RCP commands from the ground are not supported in this configuration.

• Αμφίδρομη / RCP requirement: For bidirectional communication (Βίντεο κατεύθυνσης + uplink control/data), ο VCAN2122 COFDM system is recommended, which supports both video transmission and uplink RCP/control commands.

Περίληψη:

• 1.4 GHz operation → requires RX down-converter

• One-way COFDM → video only, no RCP

• Αμφίδρομη / RCP → use VCAN2122 Σύστημα

Q: Do you have a bidirectional (αμφίδρομη) COFDM transmission system?

ΕΝΑ: Ναί, we offer a bidirectional FDD COFDM system. Παρακαλώ σημειώστε:

• Αυτό το σύστημα είναι IP-based only.

• The transmitter accepts Εισόδους βίντεο IP, and the receiver outputs IP βίντεο.

• Native SDI input/output is not supported. If your camera outputs SDI, ένα 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 (κάτω σύνδεσμος βίντεο + uplink for control/data), αλλά είναι not a native SDI-to-SDI wireless link.

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

ΕΝΑ: 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 (εμπόδια, παρέμβαση, signal degradation) μπορεί να επηρεάσει την απόδοση.

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

• Για broadcast-grade applications, που 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 τεχνική υποστήριξη, testing guidance, or configuration advice, αλλά ο final selection should be based on your project priorities and trade-offs between image quality, αφάνεια, and link stability.
