If the connected input bit rate is lower than the rate entered in the
Bit Rate
field, the ASI port will add NULL packets as required to pad it to the
desired value. PCR packets will be re-stamped as required.
If the connected input bit rate is higher than the rate entered in the
Bit
Rate
field, the ASI port will attempt to remove NULL packets from the
connected bitstream in order to achieve the desired value. PCR packets
will be re-stamped as required. If there are not enough NULL packets to
be deleted, packets will be dropped, and an alarm will be raised. This
alarm will be indicated in the Dashboard™
Card State
field, in the front
Status LED, and in the ASI Statistics page.
o
Automatic:
If this mode is selected, the
Bit Rate
field disappears. The ASI
output will exactly match the rate of the connected bit streams. However, if the
connected ports have no data, or if there is no connection to the ASI port, there
will be no output, and any connected downstream ASI device will indicate loss of
sync. The ASI Statistics page will indicate this state, as well as the rear I/O panel
indicator LED. Note that an alarm will only be raised if there is at least one
connection to the ASI output.
Bit Rate:
This field is only available if the
ASI Rate
mode is set to
Manual
. Enter the
desired ASI output bit rate here, in bits/second. The minimum value is 64,000 and the
maximum value is 213,000,000.
Transport Stream ID:
This configures the Transport Stream ID field in the Program
Association Table (PAT) coming out of this ASI port.
Original Network ID:
This field contains the Network ID code from which this program
originated. This field accepts both hexadecimal (prefixed by 0x) and decimal values.
Valid values are from 0 (0x0000) to 65535 (0xFFFF). The default value for this field is
0xFF01, which is in the range of values allocated for video over IP. The complete set of
registered Network IDs can be downloaded from this URL:
The Original Network ID field is carried in the Service Description Table (SDT). The
SDT will be present in this ASI port only if any of the encoders connected to it have the
SDT enabled.
Once the port is configured, click on the
Apply
button, and the configuration takes effect.
ASI Ports: Statistics Tab
The Statistics Tab for the ASI Ports provides a quick visual summary status for the ports. A
sample, corresponding to the table example of the previous section, is depicted below.
