Processing
Video latency is variable due to the de-glitcher but the values below apply when the video
signal is first applied.
Other latency values are maximum values.
2.3.1
SD latencies
Video:
des+4+350+256+2+ser video samples = 45.3us
Audio embedding:
2+1+16 audio samples = 19/48000 = 396us
Audio de-embedding:
4+16+1+29 audio samples = 50/48000 = 1.04ms
Embedding GPI mode:
8+4+32 96kHz samples = 44/96000 = 458us
Embedding UART mode:
32+128+17+16 96kHz samples = 193/96000 = 2.01ms
De-embedding GPI mode:
8+32+8 96kHz samples = 44/96000 = 458us
De-embedding UART mode:
8+32+8 96kHz samples = 48/96000 = 458us
2.3.2
HD latencies
Video:
des+8+1024+1024+3+ser video samples = 27.6us
Audio embedding:
2+1+8 = 11/48000 = 833us
Audio de-embedding:
2+8+1+29 = 40/48000 = 229us
Embedding GPI mode:
8+4+16 96kHz samples = 28/96000 = 292us
Embedding UART mode:
16+128+17+16 96kHz samples = 177/96000 = 1.84ms
De-embedding GPI mode:
4+16+8 96kHz samples = 28/96000 = 292us
De-embedding UART mode:
4+16+8 96kHz samples = 28/96000 = 292us
