Figure 22 - COM46 Basic Tune Screen
This page permits two different ways of tuning DIRECTV channels with Pro: Idiom encryption.
The first way specifies the destination IP address and port along with the DIRECTV channel
number. The second allows entry of a QAM channel, sub-channel and DIRECTV channel
number
Dest_IP_Address
- In this field, you will enter the IP address of the device you wish to stream
video content to (i.e. an edge QAM).
Dest_Port_Number
- This field represents the port of the IP address you wish to stream video
to. Depending upon the destination, this value may not be freely chosen.
Major_Number
- This field is equivalent to the DIRECTV channel number you tune to on a
typical DIRECTV tuner. The second way is used if a QAM6 is in the chassis. The QAM major
and minor numbers are set along with the DIRECTV channel number. The IP address will be
set to 192.168.6.(ch1) and the port will be set the QAM_Index * 16 +
QAM_subchannel.
QamMajor
- The QAM6 output QAM major channel number. This corresponds to the channel
number from the North American Cable Television Frequency Plan (see EIA-542B or
http://www.jneuhaus.com/fccindex/cablech.html ).
