Main and Line 1
Volume
These parameters determine the initial volume level the STB will
provide to the TV or monitor. Set both to same value. The volume
can be changed using the IR remote control but will revert to the
configured values at start-up.
RTSP Streaming MPEG-4 streams in Local-Fullscreen mode only. Choose the protocol
for RTSP streaming. If the source is a video-on-demand server, you must
choose UDP.
• UDP – MPEG-4 RTSP streams will be sent over UDP.
• Interleaved (TCP) – MPEG-4 RTSP streams will be sent over TCP
on the RTSP port. (Also called "RTSP Interleaved".)
• Automatic – An attempt will be made to play the stream over
UDP. If this fails, TCP will be used.
Data Buffering
Seconds
MPEG-4 only. This setting will allow more data to be saved before it
is displayed. This can be used in networks where there is a high
amount of delay variation or congestion in the network backbone, and
will "smooth" out video when the network has not been optimized.
This parameter should generally be left at the default value. However,
if an MPEG-4 stream won't open at all, set this parameter to a lower
value. The STB may reset if configured for more than 6 seconds of
MPEG-4 buffering.
Buffer Check for
Underflow.
If checked yes, a periodic check for buffer underflow will be made
using the value in
Lowest Bitrate for Buffer Check as a cutoff. Setting a
small value for Lowest Bitrate may result in disruption to low bitrate
MPEG-4 streams. This parameter should generally be left at the
default value.
Lowest Bitrate for
Buffer Check
If
Buffer Check is set to yes, and if video stream has bitrate greater
than the value, a periodic check for underflow for MPEG-4 streams
will be made. This parameter should generally be left at the default
value.
