budget wireless video transmitter and receiver

অনবরত জিজ্ঞাসিত প্রশ্ন

প্রশ্নঃ: 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.

একটি: 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-বিট 4:2:2), or workflow you mentioned. অতএব, 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.

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

একটি: 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) বিন্যাস হয় not specifically tested. Verification of HLG SDI compatibility requires an SDI source that outputs an HLG signal.

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

একটি: এই মুহুর্তে, we do not have the required equipment to test 10-বিট, 4:2:2, অথবা 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.

প্রশ্নঃ: Is your COFDM SDI video transmitter compatible with Vislink, ডোমো রিসিভার, or broadcast cameras with SDI outputs?

একটি: হাঁ, compatibility is possible, but it depends on the system configuration.

If the buyer only uses our SDI transmitter সঙ্গে 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 (ফ্রিকোয়েন্সি, ব্যান্ডউইথ, মড্যুলেশন, প্রভৃতি). এই মোডে, 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.

যাহোক, 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

• লোয়ার এন্ড-টু-এন্ড লেটেন্সি

• 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.

সংক্ষেপে:

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

• আমাদের ট্রান্সমিটার + our receiver: optional private frequency, private protocol, কম বিলম্ব, and effective AES-128 encryption

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

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

• এবং HDMI: ডিজিটাল ভিডিও, 1080p60 পর্যন্ত

• আইপি (network stream): ডিজিটাল ভিডিও, 1080p60 পর্যন্ত, UDP or RTSP

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

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

দয়া করে নোট করুন:

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

সংক্ষেপে: হাঁ, the receiver outputs full HD (1080p60) via HDMI and IP.

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

একটি:

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

• দ্বিমুখী / RCP requirement: দ্বিমুখী যোগাযোগের জন্য (ডাউনলিংক ভিডিও + uplink control/data), দ্য Vcan2122 COFDM system is recommended, which supports both video transmission and uplink RCP/control commands.

সংক্ষিপ্তসার:

• 1.4 GHz operation → requires RX down-converter

• One-way COFDM → video only, no RCP

• দ্বিমুখী / RCP → use Vcan2122 পদ্ধতি

প্রশ্নঃ: Do you have a bidirectional (দ্বিমুখী) COFDM transmission system?

একটি: হাঁ, we offer a bidirectional FDD COFDM system. দয়া করে নোট করুন:

• এই ব্যবস্থা হল IP-based only.

• The transmitter accepts আইপি ভিডিও ইনপুট, and the receiver outputs আইপি ভিডিও.

• 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 (ভিডিও ডাউনলিংক + uplink for control/data), কিন্তু এটা হয় not a native SDI-to-SDI wireless link.

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

একটি: 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 (বাধা, হস্তক্ষেপ, signal degradation) can affect performance.

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

• জন্য broadcast-grade applications, কোথায় 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 প্রযুক্তিগত সহায়তা, testing guidance, or configuration advice, তবে final selection should be based on your project priorities and trade-offs between image quality, বিলম্ব, and link stability.
