Input Processing
– All ASI modes (continuous, packet, burst) in line with DIN EN 500083-9
– Input FIFO: 8 k ± 20 transport packet burst
– Input switchover, manual and automatic
– Seamless input switching
– Input monitoring by means of Packet Lock, MIP Detect / CRC and PAT
– MFN with stuffing and PCR correction
– FIFOs can be disabled as buffers for dynamic delay changes (0.5 – 2 ms depending on
data rate)
– MIP analysis to TS 101191
– Duration of output signal interrupt after return of input signal in SFN: < 5 s
