1280*720 RGB 和 16bit depth 深度 30fps 

带宽 (bits/s) = 1280×720×24×30=663,552,000 bits/s ≈663.55 Mbps
带宽 (bits/s) = 1280×720×16×30=442,368,000 bits/s ≈442.37 Mbps

总带宽 (Mbps) = 663.55 Mbps (RGB) + 442.37 Mbps (深度) = 1105.92 Mbps

1920*1080 RGB 和 16bit depth 深度 30fps 

带宽 (bits/s) = 1920×1080×24×30=1,492,992,000 bits/s ≈1493 Mbps
带宽 (bits/s) = 1920×1080×16×30=995,328,000 bits/s ≈995.3 Mbps

总带宽 (Mbps) = 1493 Mbps (RGB) + 995.3 Mbps (深度) = 2488.3 Mbps
