HDE-8C-QAM
Instruction Manual
In the section entitled
“Multiplexed MPTS Output Configuration”
, the user can select and configure the following
parameters of the MPTS output stream:
TS ID:
user must enter the identification number for the output TS. The range is 1 to 65535. The TS ID assigned must
be unique.
TS Bitrate:
user must select bitrate for the TS. Possible options are:
•
QAM Modulator – Select this setting when using the QAM output of the encoder. The maximum bitrate will
be 38.81 Mbps for QAM 256.
•
19.39 Mbps – Select this setting when the primary encoder output will be ASI for an ATSC application.
•
38.81 Mbps – Select this setting if an external QAM 256 modulator(s) will be used with the encoder’s ASI output(s).
Modulation Mode:
user can select the modulation mode. Possible options are: Reserved, Analog, QAM64, QAM256,
8-VSB, and 16-VSB.
Out of Band:
an out-of-band (OOB) is a channel which is the combination of the forward and reverse OOB channels.
When a cable virtual channel is flagged as being out-of-band, it is carried on the out-of-band channel. Possible options
are Enable, and Disable. When Enabled, assigns the OOB bit in the TS packet and labels the TS as out-of-band.
NOTE:
As per the ATSC and Cable standards, the Modulation Mode and Out-of-Band fields are required to
be assigned in the TS packet. Selecting the above two fields would allow the TS packets to be compliant with
industry standards, but would not affect the input or output configuration of the HDE-8C-QAM.
In the section entitled
“Output Mapping”
, the user can select and configure the following parameters for each output TS
indicated by
“TS#"
, under gray header:
ASI Output:
allows the user to select any one of the four transport streams to be provided on the front panel ASI output.
Input:
indicates the list of the programs selected by the user that are included in the TS. It includes the Input
program number, video source, and audio source.
PID:
indicates the PID value assigned to each stream. PID (Packet Identifier) values are embedded by the content
provider in the MPEG-2 stream to identify tables and programming packets.
Program Number:
user must enter a unique output program number for each program. PMT (Program Map Table)
provides information on each program present in the transport stream such as program number, and the list of the
elementary streams (audio, video or data).
Short Name:
user may enter the short name of the channel. Up to 7 alphanumeric characters are allowed.
Major Channel:
user may enter the major channel number for the output program. The range is 1 to 99 for Terrestrial
and 1 to 999 for Cable.
Minor Channel:
user may enter minor channel number for the output program. The range is 1 to 99 for Terrestrial and 0 to
999 for Cable. NOTE: when zero (0) is entered as a minor channel, it sets the encoder to provide a one part virtual channel
number as entered in the major channel field. For example, a major channel of “205” with a minor channel of “0” will
be displayed on a TV “205”. A major channel of “205” with a minor channel of “1” will be displayed on a TV as “205-1”.
Save:
if duplicate values exist for PID, Program Number, Short Name or Major – Minor Channel Pair in a MPTS output
stream, when the SAVE button is clicked, the following pop-up window would appear accordingly: “Error! Duplicate
Program Numbers found”.
Please ensure the duplicate values are edited & click on SAVE button AGAIN to apply the new values/configurations.

The PID value must be unique in a MPTS output stream. If a duplicate PID exists, assign a different
PID in the range of 48 to 8176 (recommended range provided by the International Standards)
The Program Number must be unique in a MPTS output stream. If a duplicate Program
Number exists, assign a different number in the range of 1 to 65535.

Make sure that the major-minor channel pair is unique for each program on the MPTS output.
