8.5.7.3
Problems Adding Program Clock Reference (PCR)
A separate PCR component can be added to the service. The PID at the service
level must be selected to match the PID of the PCR component.
8.5.7.4
Picture in Picture (PiP) Cannot Be Configured
When the main video is set to MPEG-2, the H.264 PiP video component is not
allowed to be configured in the web GUI. The only profile selection allowed by the
GUI is
Off
.
8.5.7.5
Logo or Slate File Does Not Upload
Currently logo sizes are restricted by “width” x “height” <= 522240
i.e. logo size 720x576 is OK. Bigger logo sizes may result in unwanted behavior.
This does not affect slate operation.
The Logo and Slate file format must be OSD6. Other Logo formats (OSD5 and
OSD4) are not supported on EI9001 and EI9001T.
8.5.7.6
Automatic Loudness Control (ALC) Not Working in Fast Channel Zap mode
Audio ALC is not a requirement for Low Delay or Fast Channel Zap with Look-ahead
off
(because of an additional delay of 160 ms required for ALC operation).
8.5.8
VBI Operation Problems
8.5.8.1
Ancillary Timecode (ATC) Not Extracted and Placed into the VBI Data PES
The ATC is not a VBI component and is not part of the VBI in separate PID (VBI in
PES). The ATC is only present in the MPEG-2 Sequence/GOP header in MPEG-2
or the H.264 SEI message in H.264.
8.5.8.2
Default Value for Bar Data
There is no default / user default value for Bar Data in the EI9001T. Using a default
value of top/bottom or left/right 0 bars with AFD = 'as coded frame' is meaningless
information and has no effect on the final displayed image. Therefore the EI9001 will
only generate Bar Data if a valid external source is present (or sustain is in
operation). An externally sourced Bar Data of top/bottom or left/right 0 bars (or even
Bar Data with no flags set and no bar values at all) will be propagated through. This
behavior matches the EN8100 SD MPEG2 encoder but is different from the EN8190
operation where it inserts top/bottom = 0 when there is no other source of Bar Data.
8.5.8.3
Closed Captioning Conversion
All broadcasts in the US must have closed captions by law (according to FCC),
therefore Closed captions in MPEG-2 user data (or H.264 SEI message in H.264)
will be inserted if they are enabled by the user.
