Latency Performance Summary
Test kurulumu:
The tests were conducted with the encoder and decoder boards connected directly via Ethernet cable.
| Source Signal | Kodlayıcı Kartı | Dekoder Kartı | Decoder Display Output | End-to-End Latency |
|---|---|---|---|---|
| 1080p60 | 1746-HDMI | 2192-4K | 1080p60 | ~100 ms |
| 1080p60 | 2192-4K | 2192-4K | 1080p60 | ~100 ms |
| 4K30 | 2192-4K | 2192-4K | 4K30 | ~320 ms |
| 4K30 | 2192-4K | 2192-4K | 1080p60 | ~270 ms |
| 4K30 | 2192-4K | 2227-4K | 4K60 | ~270 ms |
| 4K30 | 2192-4K | 2227-4K | 4K30 | ~320 ms |
| 4K25 | 2192-4K | 2192-4K | 4K30 | ~270 ms |
Key Observations:
- When the source signal is 1080p60, the end-to-end latency between the encoder and decoder is approximately 100 MS, regardless of low-latency mode, due to the direct Ethernet connection.
- When the source signal is 4K30, the latency ranges from 270 ms to 320 MS, with slightly lower latency when the decoder display output frame rate is higher than the source signal.
- When the source signal is 4K25, the decoder displays at 4K30. Since the decoder frame rate is higher than the source, no cumulative delay occurs, ensuring smooth playback without frame stacking.
Çözüm:
The system demonstrates predictable and stable end-to-end latency under different resolutions and frame rates. Direct Ethernet connections yield the lowest latency for 1080p60 sources, while higher-resolution 4K signals naturally introduce longer delays. The decoder’s ability to output at a higher frame rate than the source ensures smooth playback without delay accumulation.
