Explanation of Discover Page Fields
Chassis
- This field reports a unique identifier for the chassis. In systems that contain multiple
chassis, this can be used to identify each card in the system. See Section 4.1 on how to assign
unique identifiers to multiple chassis within a system.
Slot -
This field identifies the card’s location within a chassis, numbered 1 through 6. If this
field is grey, the slot number is a link to messages in the CAM Log.
Tuner
- There are eight entries per CardIP for this column. This represents the eight tuners
available on each COM46 card.
QAM or IP Address
- If some of the programs are streaming to a QAM6, then “QAM” is
displayed as the column header. If all signals are routed out of the system, then “IP Address”
will display as the column header instead. If the card is sending video to a QAM6, this field
shows a snapshot of the output QAM channel and QAM sub-channel number. If a card is
streaming video to outside of the chassis, this field will contain the destination IP address. Both
unicast and multicast addresses are supported.
Bitrate or Port
- If some of the programs are streaming to a QAM6, then “Bitrate” is displayed
as the column header. If all signals are routed out of the system, then “Port” will display as the
column header instead. If the card is sending video to a QAM6, this field shows the
instantaneous bitrate of the channels being sent out of the QAM6. Otherwise this field contains
the destination port associated with the destination IP address described above. You must have
a unique port number for each individual channel you wish to stream.
Channel
- This field shows the Channel Name and the DIRECTV channel number you tune to
on a typical DIRECTV tuner. This field is also a link that permits the user to change channels.
If the smart card has not been authorized or paired then the channel will be highlighted in red.
SNR
- This field returns the Signal-to-Noise Ratio associated with the selected tuners. If the
SNR is low, it will be highlighted in yellow and if the SNR is very low, it will be highlighted in
red. For optimum performance of the COM2000, this value should be 11 or higher.
Strength
- This value provides a value corresponding to the internal Automatic Gain Control
setting in the COM46. If the Strength is low, it will be highlighted in yellow and if the Strength
is very low, it will be highlighted in red. For optimum performance of the COM2000, this value
should be somewhere between -25 and -55.
