1080i50 H265 2.2-2.7Ghz HDMI transmitter and receiver

Do you need 1080i50 H265 2.2-2.7Ghz HDMI transmitter and receiver?

I require a 1080i50 HDMI(SDI) connection with wireless capabilities, using H265 encoding, operating within the frequency range of 2.2 до 2.7 GHz.What is the expected delay for your set?

для a wireless video transmission system that meets the following specs:

• Вхід/Вихід: HDMI або SDI (1080i50, broadcast TV standard)
• Відеокодек: H.265 (HEVC)
• Діапазон частот: 2.2 – 2.7 GHz (suitable for COFDM systems, licensed/regulated bands)
• Випадок використання: TV station, professional live broadcast
• Бездротовий: Point-to-point or mobile (camera-to-base)

May I know that h265 vs lower latency, which is important for you? can not support both. Is 2.2-2.7G mandatory? The default frequency range is 170-860MHz. If 2.2G must be supported, then an up-converter must be used on the transmitter and an down-converter on the receiver. I will recommend a most suitable model Vcan1726.

🎯 Typical System Latency (H.265, COFDM, 2.2–2.7 GHz)

компонент	Approximate Delay
H.265 Encoding	50–150 ms (depends on hardware performance)
COFDM Transmission	20–50 мс
H.265 Decoding	30–100 ms
Total End-to-End Delay	✅ 100–300 мс (best case: ~150 ms)

⚠️ Key Factors Affecting Latency

1. Encoder Type: FPGA-based or hardware SoC (напр. HiSilicon) performs faster than software encoders.
2. резолюція & Частота кадрів: 1080i50 is interlaced, and compression may introduce 1–2 frame delay.
3. FEC & Interleaving (in COFDM): If Forward Error Correction is high (напр. 3/4), latency increases slightly.
4. Modulation Scheme: QPSK/16QAM/64QAM – higher modulation may increase complexity but allow better data rate.
5. Wireless Conditions: Stronger signal = lower latency. Moving cameras or non-line-of-sight adds delay or jitter.

📦 If You Use a High-Performance H.265 COFDM Wireless Kit

• Expected latency:
  🔵 150ms ±50ms (realistic for professional-grade equipment)
• Ultra Low Latency Options (custom build or very high-end systems):
  🟢 Down to 70–100ms, but usually with H.264 + reduced GOP + low-latency mode

✅ Example Use Case Performance

Випадок використання	Latency Estimate
Fixed camera to OB van (прямої видимості)	~150 ms
Handheld camera with movement, same band	~200 ms
Through walls / NLOS	~250–350 ms (may need signal repeaters)
