Time Taken for an Output Service to Appear when Transcoding Using EI9001T
When the AVP 4000 fitted with an EI9001T transcoder is fed with an input, it may
take up to 60 seconds to: output the transcoded service and the
No Data Available
from input TS
to be cleared from the GUI. This is due to the network handshakes
taking place.

Restrictions on DVB Subtitles Pass-thru
8.5.11.1
DVB Subtitles Not Supported When Outputting Down-converted Video
DVB-Subtitles are not supported when the input is HD and the encoded output is
SD. DVB-Subtitles are passed through and not modified to match the format of the
encoded video output.
8.5.11.2
DVB Subtitles Bit Rate Setting
During the configuration of DVB-Subtitles pass-thru, the user is prompted to enter a
bit rate value for the
DVB Subtitles Bit Rate
.
Figure 8.1 DVB Subtitles Bit Rate
The bit rate for DVB-Subtitles is bursty and can fluctuate between 0 bps to few
hundred kbps. This bit rate setting is to ensure the pipe allocated for DVB-Subs is
big enough to avoid overrating the TS output. This is especially useful in bit rate
tracking mode.
8.5.12
Video Recovery Delay When Switching MPEG-2 to H.264
It takes up to 20 seconds for the encoder to switch its output from MPEG-2 to H.264.
We recommend the configuration is not changed during this period.
8.5.13
Alarms Raised for (DSP is Not Responding to its Controller)
If this alarm is raised, the unit is indicating that an internal processing block is not
responding to its controller. The reason for the failure to respond may result in loss
of audio component. The loss of audio may be immediate or only exhibit itself when
the unit is reconfigured (for example during a redundancy switch).
If this alarm is indicated, Ericsson recommends that the unit is rebooted. If the alarm
persists after reboot, the issue may be a result of an invalid incoming audio stream.
