B.TransmissionConfig page:

Modulation data rate should be larger than video encoder (compression) "Max bit rate(kbps)" by 50%. For example,

if video encoder (compression) "Max bit rate(kbps)" is 8000Kbps, modulation data rate is recommended to be

12000Kbps. Change the transmission parameters properly to fit this requirement.

C.In TSInfo Page:

Increase "PTS PCR Latency (ms)" to a larger value, say 1000ms or larger.
