Data Pattern
(Data) PN9, PN15, PN23, ALL0, ALL1, 0101, Null TS, TS File "LP" cannot be set when No.2 = Non-hierarchical.
When TS File is selected, the external TS le is read. The TS le is composed of several packets with 188 bytes/
packet. The rst one byte of the packet becomes the Sync Byte and is set to 47 (HEX). If a TS le that does not
follow the format of this TS data is selected, an error is displayed when the Calculation button is clicked.
When all of "Outer Coder," "Outer Interleaver," "Inner Coder," and "Inner Interleaver" are set to ON, Sync Byte is
set to the data of "PN9/PN15/PN23/ALL0/ALL1/0101". At this time, the continuity of data is kept between the "last
data of the packet" and the "rst data of the next packet except the Sync Byte."

ON, OFF OFF: When No.1 = DVB-T
OFF: When No.4 = 8K
OFF: When No.13 = OFF
17 Time Slicing ON, OFF: When Time Slicing = ON, the 49th bit of the
TPS data is set to "1".
When Data Pattern = TS File, Time Slicing
processing is required in the selected TS le.
OFF: No.1 = DVB-T
"LP" cannot be set when No.2 = Non-hierarchical.
18 MPE-FEC ON, OFF: When MPE-FEC = ON, the 50th bit of the
TPS data is set to "1".
When Data Pattern = TS File, MPE-FEC
processing is required in the selected TS le.
OFF: When No.1 = DVB-T
"LP" cannot be set when No.2 = Non-hierarchical.

Optional
The data processing changes according to the "Size of TS File"
and "Setting of Number of Super Frames" when TS File is selected
at "Data Pattern". The TS File data is annulled when the "TS File
data number" is greater than the "Data number equivalent to the
set number of super frames." When the "TS File data number" is
smaller than the "Data number equivalent to the set number of
super frames", the same TS File data is repeated from the header.
● Number of Super Frame Setting
The "Number of Super Frame" setting range changes according to
the "Mode" setting and "MG3700A main frame memory option" as
shown in the following table.

The data selected by "Data Pattern" is annulled in the terminal of
the final super frame set here.
