延遲效能總結
測試設置:
測試是透過乙太網路電纜直接連接編碼器和解碼器板進行的.
主要觀察結果:
- 當源信號為 1080P60, 編碼器和解碼器之間的端對端延遲約為 100 女士, 無論低延遲模式如何, 由於直接乙太網路連接.
- 當源信號為 4K30, 延遲範圍為 270 女士至 320 女士, 當解碼器顯示輸出幀速率高於來源訊號時,延遲稍低.
- 當源信號為 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.
結論:
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.
