1080i50 H265 2.2-2.7Ghz एचडीएमआई ट्रांसमीटर और रिसीवर

क्या आपको 1080i50 H265 2.2-2.7Ghz HDMI ट्रांसमीटर और रिसीवर की आवश्यकता है?

मुझे 1080i50 एचडीएमआई की आवश्यकता है(एसडीआई) connection with wireless capabilities, using H265 encoding, operating within the frequency range of 2.2 को 2.7 GHz.What is the expected delay for your set?

एक के लिए wireless video transmission system that meets the following specs:

• इनपुट आउटपुट: HDMI or SDI (1080i50, broadcast TV standard)
• वीडियो कोडेक: एच.265 (एचईवीसी)
• आवृति सीमा: 2.2 – 2.7 गीगा (suitable for COFDM systems, licensed/regulated bands)
• उदाहरण: TV station, professional live broadcast
• वायरलेस: 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 वीकैन1726.

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

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

⚠️ Key Factors Affecting Latency

1. Encoder Type: FPGA-based or hardware SoC (उदाहरण के लिए:. Hisilicon) performs faster than software encoders.
2. संकल्प & फ्रेम रेट: 1080i50 is interlaced, and compression may introduce 1–2 frame delay.
3. एफईसी & Interleaving (in COFDM): If Forward Error Correction is high (उदाहरण के लिए:. 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 264 + reduced GOP + low-latency mode

✅ Example Use Case Performance

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