Configuring the Transmitter Chapter 6
44 VIP 10 / VIP 1000
There are several pre-programmed profiles available for both MPEG encoders.
These are optimized for different application scenarios. Individual settings in a
profile can be changed, and the modified profile can be saved under a new name.
Warning!
The profiles are rather complex. They include a number of parameters that
interact with one another. Therefore it is generally best to use the profiles
as provided. The profiles should only be changed after you have
familiarized yourself with all the configuration options.
You can switch between the parameters of the two MPEG-4 encoders by clicking
the associated tabs. The choice of Video Livepage encoder is set on the
Livepage configuration page (see page 62).
Note
The parameters as a group constitute a profile and are dependent on one
another. If you enter a setting outside the allowed range for the parameter,
the nearest valid value will be substituted when the settings are saved.
Name of first (second) encoder:
Enter a unique name for each encoder. The name of the encoder will also be
shown on the
Livepage configuration page.
Parameter preset:
Eight pre-programmed profiles are available for each of the two MPEG-4
encoders. These are optimized for different transmission modes:
]
high quality (CIF)
for connections with high bandwidth, resolution 352 × 288 pixels
]
high res. (2CIF)
for connections with high bandwidth, resolution 704 × 288 pixels
]
low res. (QCIF)
for connections with low bandwidth, resolution 176 × 144 pixels
]
DSL
for DSL connections with 500 kbit/s
]
ISDN (2B)
for ISDN connections via two B channels
