The following table shows which PIDs will count as part of the StatMux group, and which PIDs
will not count as part of the StatMux group:
Module
PIDs inside StatMux group
PIDs outside StatMux group
Encoder
Video
PCR
Audio
Passthrough AC-3
1
PIP
VBI/VANC
PSI/SI (PAT, CAT, PMT, NIT, EIT etc.)
Transcoder
Video
PCR
Audio
Passthrough PIDs
3
PIP
PSI/SI (PAT, CAT, PMT, NIT, EIT etc.)
When AC-3 passthrough audio is enabled, a fixed bitrate of 640kbps is reserved
for AC-3 inside the group
Transcoder pass-through PID's are shown under the transcoder properties
dialog by clicking any transcoder under the Coders tab
8.7.2.4 StatMux Service Status
The status tab will bring up the program status with history view up to 24 hours. The following
status is available per program:
• Video Bitrate: Bitrate allocated by the video PID in this program.
• Activity: Informal measurement of frame-to-frame video activity and estimated bitrate
requirements for this program. A low activity indicates a still picture while a high activity
indicates rapid scene changes. A HD channel will have a higher video activity (and
higher bitrate requirements) than a SD channel.
• Distortion: Informal measurement of video distortion after encoding, based on the
amount of quantization introduced per video frame. A low distortion value indicates that
a low QP and a high VQ was achieved.
Four different time scales are available: 5 min (Live), 1 hour, 5 hours and 24 hours.
