Dest_Port_Number - This field represents the destination port of the IP address you wish to
stream to.
Protocol_Type - This field is used to control whether the COM51 streams the data in UDP
or RTP packet structures. The default value is UDP.
Channel_Object_ID - This field is the data that the COM51 uses for tuning purposes.
➢ It will be automatically filled in when a valid AT&T / DIRECTV channel number is entered in
the “Major_Number” field.
➢ Before the card has been successfully tuned, the default value is 0.
Major_Number - This field is equivalent to the AT&T / DIRECTV channel number you
tune to on a typical AT&T / DIRECTV tuner.
The default value is 0.
Minor_Number - This field is automatically filled in by the COM51 card, with a default
value of 65535.
➢ If the AT&T / DIRECTV channel has a minor channel number then the Minor_Number value
must be entered.
➢ Many AT&T / DIRECTV channels have both high-definition and standard-definition channels
with the same Major and Minor numbers. The COM51 will default to the high-definition
channels when tuned from this field. To set the standard-definition channels instead, add
100000 to the Minor_Number. In most cases, this would cause the Minor_Number to be
165535 if the standard-definition channel is desired.
