Setup and Programming (Continued)

Choose the SELECT PROGRAMS setting to allow the

operator to pick which programs from the A and B inputs are

to be included in the output multiplex.

NOTE: At this point you may proceed through the remaining

menus, below, before pressing the ENTER button to load the

selected data OR you may press ENTER now and then come

back to the rest of the menus. In any case, when the ENTER

button is pressed, one of the following two actions will occur:

A) If SELECT ALL PROGS 

has been selected, the MEQ1000A

will now read PAT tables from the two input streams and dis-

cover which MPEG programs are defined. If you wish to view

the MPEG program numbers of programs that were found, fol-

low the procedure below:

 

VIEWING MPEG PROGRAM NUMBERS

 

In order to see the MPEG program numbers of incom-

 

ing streams, the following procedure can be followed:

 

1) Press the ENTER button for 2 seconds to enter pro-

 

gram mode. Release button. Display will be flashing.

 

2) Press the ENTER key again and hold. By continuing

 

to hold in the ENTER button, the following display will

 

be slowed down so that program numbers can be read

 

as they scroll by.

 

3) A screen will be displayed that indicates:

 

PMT PROG A xxxx or PMT PROG B xxxx.

 

4) The xxxx field will be a number that corresponds to

 

the MPEG program number of a program found in the

 

PMT table for the indicated (A or B) input. As the button

 

is held, all entries for input A will scroll past and then

 

entries for input B will scroll past.

 

5) Release button and if necessary repeat steps 1 - 4.

B) If SELECT PROGRAMS

 was chosen, the unit will read

the PAT tables from both inputs and then display:

MPEG PROG XXXXX: (XXXXX is a number from 00001 to

65535) on the top line of the display. Using the right and

left arrow keys, you can scroll through all 65535 possible

program numbers.

Don't be alarmed by the large number of possibilities

because if the arrow key is held down, the scrolling will

speed up so all 65535 possible numbers can be scanned in a

short time - any time an entry is found at a given program

number, the scrolling will slow down to give the operator time

to see it and stop scrolling, if desired. Usually, all programs

are known to be numbered between 01 and 20.

For each MPEG program number, displayed on the top line,

the bottom line, on the right, will indicate A, B, AB, or nothing.

This will indicate that the program number on the top line was

found in input A or B or AB for both or not in either one if

blank.

To select programs to be included in the output multiplex,

use the up and down arrow keys to select NOT SELECTED,

INPUT A, INPUT B, or INPUT A+B. If NOT SELECTED is

used, then this program number will not be present in the

output and any programs with this program number that are

present in the A or B inputs will be filtered out. If INPUT A is

selected, the A input program only is used.

This section provides additional details regarding the

selectable items shown in the ‘adjust’ mode on the

Software Flow Chart on page 8.

SETUP: MEQ1000

(For Specific EAS and DTA Settings, Refer to Page 14)

UNIT ID: 

Select the desired unit identification number when

connecting the 'RS232 IN' connector to a PC or modem for

remote control using 'Drake Remote Control Software'.

Numbers 1 thru 63 may be used. If zero (0) is selected, the

PC will ignore the unit.

RS232 BAUD RATE: 

This setting determines the baud

rate at which the MEQ1000 communicates with the remote

PC. Settings available are 2400, 4800, 9600 and 19,200.

All units 'daisy chained' to the remote PC or modem must

be set to the same baud rate.

MULTIPLEX: 

This setting determines whether the Input

Module Slot A input is to be multiplexed with a second

input (if installed). Select Input Module Slot A to activate the

A Input Module only. Select Input Module Slot B to activate

the B input module only. To turn on the multiplex function

select ENABLED. If either A or B Input module is selected,

the next menu will be the QAM MODE menu. You may skip

to that paragraph, below.

INPUT B OFFSET: 

When the Input Module Slot B or ASI

input has been installed and selected in the MULTIPLEX

menu, this menu will be present. Because the two incoming

transport streams are likely to have overlapping use of

MPEG program numbers, the MEQ1000 will pass the

program numbers from input A unchanged and an offset,

equal to the value chosen in this menu, will be added to the

program number of programs from the second input. This

same offset value will also be added to the minor channel

number in the VCT table for programs from the second

input source. Usually an offset of 10 will be adequate but if

you know there are programs in the signal input to input A

using program numbers above 10, a higher offset may be

required. Values between 10 and 90, in increments of 10,

are available for selection. When it is known that there is

no overlap between input A and input B stream program

numbers, a 0 offset setting can be used. Be cautious if this

is the selection that is chosen.

MPEG PROGRAMS: 

This menu provides selections to

determine which programs are multiplexed to form the new

multiprogram transport stream output that will be supplied

to the QAM modulator section. Choose the SELECT ALL

PROGS setting to multiplex all programs from inputs A

and B up to 20 programs maximum. If more than 20 exist,

you must use SELECT PROGRAMS and only select 20

maximum.

It is the operator's responsibility to be sure that the total

data rate of these programs does not exceed the maximum

data rate for the output QAM mode that will be used,

typically 26.98 Mbps for 64QAM or 38.8 Mbps for 256QAM

in ITUB modes. If the sum of input bitrates would exceed

this amount, or if more than 20 programs are present,

some programs will have to be dropped from the list of

selected programs.
