Usually we assign two programs per one output. This page depicts all programs coming from
the 8 HDMI inputs and their settings.
For each program the HCL-804CT provides the following information:
Service Name –which is the name of the program
Service ID –which is the Service ID number of the program
LCN No –which is the logic channel number of the program
Bandwidth –which is the bitrate of the program
Figure No 6
Using the Drop down menu from “Output” column (Figure No 6) the user is able to assign any
program to anyof the four outputs. Bydoing the same process for each program, from all inputs
the user is able to create the 4 custom multiplexes in device’s output.
Caution!
The number of programs that the HCL-804CT can distribute on its output depends on the video
bitrate that the user selects for each program.
For example, if we select the following DVB-T setting for the four modulators on HCL-804CT
outputs:
Constellation: 64 QAM
Guard Interval: 1/32
Code rate: 7/8
Bandwidth: 8MHz
According to Appendix A we will have a total output bitrate of 31.67Mbps/ modulator. That
means that we can select as many programs but their total bitrate must not exceed the
31.67Mbps, otherwise artifacts may occur.

Figure No 7
The status section in (Figure No 7) provides a general idea to the user of the current payload
(according to the selected programs) comparing to the max. output payload.
It is recommended that the user must not exceed the 85% from each output, since all the bitrate
are variable according to their specific content.
Peak Detection mechanism
As shown in Figure No 7 there is a colored indicator of the peak detection mechanism, for each
output transport stream. This indicates if any overflow has occurred on modulator’s output
bitrate with the following colors:
Green –No overflow occurred
Yellow –No overflow occurred but the input bitrate is close to the output bitrate
Red –Overflow occurred. The user must decrease the input bitrate

* All the four outputs of the HCL-804CT operate in adjacent RF output channels. This means
that the user setups only the first modulator and all the other three modulators have the same
settings and automatically are being program in adjacent channels.
E.g. If the user sets the CH21 in UHF band on modulator No1 the other three modulators will
be automatically set to CH22, CH23 and CH24, respectively.
Figure No 9
The status section in (Figure No 9) provides a general idea to the user of the current payload
(according to the selected programs) comparing to the max. output payload.

In order to setup the IP address for each program there are four tabs one for each IP output of
the HCL-804CT.
By selecting e.g. the TS1 tab (Figure No 11) the user is able to setup the IP streamer for this
specific output, following the steps below:
1st step: Select SPTS or MPTS streaming mode.
SPTS mode: Means that each program has its own IP
MPTS mode: Means that all the programs of the current output (e.g. TS1) will be
streamed in a single IP.
2nd step:For each program (in SPTS mode) or for the whole TS (in MPTS mode) the user is
able to assign a multicast IP address from 224.0.0.0 to 239.255.255.255 or a unicast
IP address as well as its destination port and protocol (UDP or RTP).
By repeating the above procedure for all four outputs of the HCL-804CT, the user is able to
setup the IP streamer of the device.
