SDE24 Dual SD MPEG Encoder HDE24 High Definiton MPEG Encoder SDI24A SDI/HD-SD I Input Encoder

The MEQ1000A has tw o input m odule slots and the outputs interface to the MEQ1000A multiplexer, internally, w here they are MPEG program filtered, m ultiplexed, and groom ed. Programs, among the total group from input m odule A and input m odule B, m ay be selected or not selected by the operator to be sent to the QAM m odulator. Each input must contain no more than 20 programs and a m axim um of 20 program s per input m ay be selected. Also, the total bitrate of the selected programs m ust not exceed that of the output QAM channel capacity.

Som e common applications include: Channel Drop/Add, cherry picking program s from ASI MPTS inputs, digital channel processing, or local origination additions.

The MEQ1000A contains a high perform ance QAM m odulator that can operate in m ost ITU-A or ITU-B m odes up through 1024QAM. The very low noise, high output, upconverter pro vides coverage from 54 MHz to 1002 MHz w hile m aintaining exceptionally low phase noise and broadband noise. Output level can be selected at a value between + 45 dBmV and + 61 dBmV.

The MEQ1000A operates in a fixed output clock mode and processes null packets when required to m aintain the

set fixed clock rate. PCR correction is included. DIGITAL CH ANNEL PROCESSING (One input module)

The D TD1000 input m odule tunes any 8-VSB or QAM channel betw een 54 MHz and 1002 MHz. It is ideal for digital 'channel processing' applications w here a single digital video signal is received, error corrected, clocked at a user determ ined fixed rate and rem odulated on the sam e or another RF channel. Applications include cleaning up a low MER QAM signal received from a CATV source or fiber link receiver, or shifting the RF frequency of a QAM

m odulated signal. It m ay be used to convert one off-air ATSC 8VSB signal to a QAM output w ith rate adjustm ent. Used in the processor mode w ith only one input, the MEQ1000 can process ATSC or CA TV QAM inputs. No multiplexing or altering of any MPEG tables is perform ed in this mode.

Used in the non-m ultiplexing m ode, the data rate of the incom ing signal can be any rate that falls w ithin the specification range. The output rate can be set to any fixed output rate (equal to or faster than the input rate).

MULTIPLEXING TWO ATSC TR ANSPORT STRE AMS Utilizing tw o DTD1000 input m odules, tw o off-air 19.4 Mbps ATSC

signals (QAM m odulated CATV delivered signals could also be used) can be received and m ultiplexed to obtain a 38.8 Mbps 256QAM output. Thus tw o ATSC inputs can be output on a single 6 MHz bandwidth 256 QAM channel.

Another way of com bining tw o ATSC 19.4 Mbps stream s is to receive the first stream using the 8VSB input (DTD1000) and input the second stream , if available in ASI form at, through the ASII m odule in the second input slot. Again the tw o combined ATSC signals will be m odulated at 256QAM in a 6 MHz w ide channel. If it is desired to provide both ATSC signals from tw o ASI sources, tw o ASII m odules can be used.

W hen the MEQ1000A is used as described above, no loss of picture or sound packets occurs. There is no added compression of the video or audio streams. Only the necessary control packets are rew ritten to prevent duplication of MPEG2 program num bers and m ajor and minor channel number assignments in the tables.

Using a PC interface, the operator can select the m ajor and m inor program num bers that he desires for each program in the output m ultiplex.

PROGRAM FILTERING A 'Select Program' function is provided to allow the operator to

select w hich of the MPEG program s present on the A and B input stream s are to be included in the output m ultiplex.

PSIP OPTIONS W hen operating in the multiplex m ode, the MEQ1000A can be set

to process PSIP inform ation from both sources and rew rite tables containing com bined PSIP inform ation, or in cases w here the offair broadcast channels may not be transmitting som e or all of the tables, it can be set to ignore and discard the PSIP tables com pletely, or it can be set to generate MGT and VC T tables w ithout EIT tables. Null packet processing is applied as necessary to keep the output data rate at the desired setting. PCR correction is provided. The operator can program desired major and m inor channel num bers for each program in the output stream .

OUTPUTS - RF and ASI The 54 to 1000 MHz RF output is alw ays QAM regardless of

w hether the input is VSB or QAM. This sam e filtered stream is also output via the rear panel ASI output jack.

Setup and Programming / Software Flow Chart 9

Programming and viewing of the various setup and operating parameters is accomplished using the front panel back lit, two line, sixteen character wide LCD along with the two LEFT and RIGHT SELECT buttons and the five LEFT, RIGHT, UP, DOW N and ENTER buttons.

The name of the parameter is on the top line of the display and the setting value is on the bottom line. To observe a certain parameter setting without intending to change its value, just use the LEFT and RIGHT SELECT buttons and the LEFT and RIGHT arrow buttons to navigate through the menus shown in the software flow chart below.

The current setting f or each parameter is shown on the bottom line of the display.

Note that depending upon certain settings, some screens are not needed and will be skipped.

To make a change in the displayed parameter and its setting and if this is the initial setup, you will want to enter the ‘adjust’ mode. To do this, press the ENTER button that is located in the center of the f our arrow buttons and hold in f or several seconds until the display begins to flash. After you are in the adjust mode (bottom line of screen flashing) use the left and right arrows to

navigate among screens and use the up and down arrows to change the parameter setting. W hen ENTER is pressed, the new settings will be loaded and stored and the unit will exit the ‘adjust’ mode. You may wish to not press ENTER until you have gone through all screens and settings and then press ENTER to save and load all changes in one step OR you can store just one or several parameters at a time and reenter adjust mode to set the next.

Either method is acc eptable.

Page 10

This section provides additional details regarding the selectable items shown in the ‘adjust’ m ode 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 w hen

connecting the 'RS232 IN' connector to a PC or m odem for rem ote control using 'Drake Remote Control Softw are'. Num bers 1 thru 63 m ay be used. If zero (0) is selected, the PC will ignore the unit.

RS232 BAUD R ATE : This setting determ ines the baud rate at w hich the MEQ1000 comm unicates with the rem ote

PC. Settings available are 2400, 4800, 9600 and 19,200. All units 'daisy chained' to the rem ote PC or modem m ust be set to the same baud rate.

MULTIPLEX: This setting determines w hether the Input Module Slot A input is to be m ultiplexed w ith 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 m odule only. To turn on the m ultiplex function select ENABLED. If either A or B Input m odule is selected, the next m enu w ill be the QAM MODE menu. You m ay skip to that paragraph, below .

INPUT B OFFSET:W hen the Input Module Slot B or ASI input has been installed and selected in the MULTIPLEX m enu, this m enu will be present. Because the tw o incoming

transport streams are likely to have o verlapping use of MPEG program numbers, the MEQ1000 w ill pass the program num bers from input A unchanged and an offset, equal to the value chosen in this m enu, will be added to the program num ber of programs from the second input. This sam e offset value w ill also be added to the m inor channel num ber 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 m ay be required. Values betw een 10 and 90, in increm ents of 10, are available for selection. W hen it is know n that there is no overlap betw een input A and input B stream program num bers, a 0 offset setting can be used. Be cautious if this is the selection that is chosen.

MPEG PROGRAMS: This m enu provides selections to determine w hich program s are m ultiplexed to form the new m ultiprogram transport stream output that w ill be supplied to the QAM m odulator section. Choose the SELECT ALL PROGS setting to multiplex all program s from inputs A and B up to 20 program s m axim um . If more than 20 exist, you m ust use SELECT PROGRAMS and only select 20

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

data rate of these program s does not exceed the m aximum data rate for the output QAM m ode that will be used, typically 26.98 Mbps for 64QAM or 38.8 Mbps for 256QAM in ITUB m odes. If the sum of input bitrates w ould exceed this amount, or if more than 20 program s are present, som e program s will have to be dropped from the list of selected programs.

Choose the SELECT PROGRAMS setting to allow the operator to pick w hich program s from the A and B inputs are to be included in the output m ultiplex.

NOTE: At this point you m ay proceed through the rem aining m enus, below , before pressing the ENTER button to load the selected data OR you m ay press ENTER now and then come back to the rest of the menus. In any case, w hen the ENTER button is pressed, one of the follow ing tw o actions w ill occur:

A) If SELECT ALL PROGS has been selected, the MEQ1000A w ill now read PAT tables from the tw o input stream s and discover w hich MPEG programs are defined. If you w ish to view the MPEG program num bers of programs that w ere found, follow the procedure below :

VIEWING MPEG PROGR AM NUMBERS In order to see the MPEG program num bers of incom -

ing streams, the following procedure can be follow ed:

1) Press the ENTER button for 2 seconds to enter program m ode. Release button. Display w ill be flashing.

2) Press the ENTER key again and hold. By continuing to hold in the ENTER button, the following display will be slow ed dow n 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 w ill be a num ber that corresponds to the MPEG program num ber 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 w ill scroll past.

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

B) If SELECT PROGRAMS w as chosen, the unit w ill read the PAT tables from both inputs and then display:

MPEG PROG XXXXX: (XXXXX is a num ber 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 num bers.

Don't be alarm ed by the large num ber of possibilities because if the arrow key is held dow n, the scrolling w ill speed up so all 65535 possible num bers can be scanned in a short tim e - any time an entry is found at a given program num ber, the scrolling w ill slow dow n to give the operator tim e to see it and stop scrolling, if desired. Usually, all programs are know n to be num bered betw een 01 and 20.

For each MPEG program num ber, displayed on the top line, the bottom line, on the right, will indicate A, B, AB, or nothing. This w ill 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 program s to be included in the output multiplex, use the up and dow n arrow keys to select NOT SELECTED, INPU T A, INPU T B, or INPU T A+B. If NOT SELECTED is used, then this program num ber w ill not be present in the output and any program s with this program num ber that are present in the A or B inputs w ill be filtered out. If INPUT A is selected, the A input program only is used.

Page 11

Setup and Programming (Continued) 11

If INPU T B is selected, the B program is used and A filtered out. If INPU T A+B is chosen, then both are accepted if present.

Note: It is OK to use this menu to set up desired program selections 'off line'. That is, w ith no actual input at the present tim e. Programs m ay be selected that m ay not currently be in the input stream but are desired at som e future tim e.

Note: It is possible to select both programs w ith the same program num ber - one from A and one from B as long as the INPU T B offset is set so that the B program num ber plus the offset am ount does not duplicate a program num ber from the A input. The offset is not included in the MPEG program num ber display being discussed above but the offset will be added to all MPEG program numbers from the B input w hen they are added to the output m ultiplex.

PSIP: This menu provides a choice of how the unit organizes the PSIP inform ation from tw o ATSC stream s that

are being m ultiplexed. In the ENABLED setting, inform ation from the MGT and

VCT tables from both signals will be used to build a new table for the com bined output signal. Both input streams m ust have these tables present in order for the unit to be able to perform this operation. EIT tables w ill be processed so as to provide program inform ation, if present, for the next 12 hours. This selection is the only one that passes EIT table program inform ation to the m ultiplexed output signal. RRT and S TT tables from Dem od A are passed through.

If the broadcast station is not transmitting com plete MGT and VCT tables, the ENABLED selection cannot be used. In this situation, DISABLED may be selected. In DISABLED mode, the unit does not process or output any MGT, VC T, or EIT tables. This can be a fine solution for cable systems that use set top boxes w hich operate from their ow n system channel map and have no need for these tables. MPEG program inform ation is still processed. Some retail consum er QAM set tops operate perfectly in this m ode and others m ay not.

The third option is the BASIC MGT, VC T choice. W hen this selection is made, the MEQ1000 will build its ow n MGT and VCT tables from the incom ing streams even if one or both of the streams do not contain these tables. This solution should satisfy all types of set top boxes but w ill not provide any EIT table program guide inform ation.

The S TT and RR T tables from the source are passed through unchanged in the ENABLED m ode and filtered out in the other m odes.

VCT TABLE : This menu is only available w hen ENABLED or BASIC MGT, VC T has been selected in the previous PSIP m enu. You m ay select the TVCT - TV channel table or

CVCT table for CATV. Usually the TVC T choice m ust be selected for ATSC input signals.

MAJOR CH ANNEL: This m enu is not available if PSIP is disabled. This setting will determ ine how a channel num ber is displayed on a consum er TV if the TV is tuning the output of the MEQ1000A without a cable box.

W hen ORIGINAL is selected, the m ajor channel num ber indicated in the output tables w ill be that sent by the original broadcaster. If OUTPU T CHANNEL is selected, the m ajor channel num ber w ill be set to the channel num ber of the MEQ1000A RF output channel. W hen a cable box is used, it usually does not require or use this inform ation. Minor channel numbers are the sam e as those input via m odule A and as input via m odule B with the offset added to the B side program s.

W hen USER DEFINED is selected and the rem ote control softw are is used to allow programm ing via a PC, then the MPEG program number and the m ajor and minor virtual channel num bers may be set to w hatever num ber the operator chooses providing total flexibility. These num bers cannot be programm ed w ith the front panel buttons but only via a PC and the RS232 interface of the MEQ1000A. It is up to the operator to insure that no duplications are m ade when using this mode.

QAM MODE : This menu allow s the user to set the m odulation type for the output. Choices range from 16-QAM through 256-QAM. 'A' suffixes indicate DVB com pliant FEC and the 'B' suffixes indicate DigiCipher II FEC encoding. Note that w hen using the MEQ1000A in the m ultiplex m ode, the output QAM m ode usually must be 256-QAM. For CATV systems using DigiCipher II, select the QAM-256B m ode.

For DISH Netw ork QAM distribution or other DVB systems using DVB set tops, choose the QAM-256A m ode.

W hen used for a single input processing function, choose the output m ode accordingly from any of the available options that will provide a high enough data rate.

GRAY ENCODING: This m enu is only available w hen QAM m odes QAM-16A through QAM-1024A, are selected. The choices are DVB and DAVIC. Gray Encoding is norm ally not used for video data.

QAM SYMR ATE : Preset or Manual: If PRESET is selected, the symbol rate will be autom atically set to the

‘normal’ rate based on the QAM m ode that is selected and assuming a 6 MHz w ide QAM channel. If MANUAL is selected, pressing the right or left arrow buttons w ill allow selection of sym rates from 1.000 thru 7.000 MSym /Sec using the up and dow n arrow buttons.

QAM SYMR ATE : This m enu allow s selection of the output QAM baudrate or sym bol rate. Set as required by the set top box. W hen m ultiplexing tw o ATSC input signals, in DigiCipher II, 256-QAM CATV systems, this is usually

5.3606 Ms/s. In DVB systems, the rate w ould be 5.264 Ms/s. In any case, the rate m ust be high enough to provide a data bitrate of at least 38.81 Mbps (do not confuse this w ith the sym bol rate). If the set top box requires a fixed higher rate, this may be m anually set.

14 DTA/EAS Considerations and Additional Information

DTA and EAS (EM ERGENCY ALERT SYSTEM ) CONSIDERAT IONS

Any headend using DTAs or EAS (Em ergency Alert System ) that includes the MEQ1000A must be setup with one EH24A / EH244 / EH244-IP being the “Master” device and the MEQ1000A and all other additional Drake Headend Products (EH24A / EH244 / EH244-IP / other additional MEQ1000A) being “Slave” de vices.

DTA/E AS CONTROL: The D TA control is used w hen MEQ1000As are used to supply the QAM signals to DTA set top boxes. It allows for an ASI stream , generated by a PC to be input to the headend’s Master unit. This control allow s for generating

a transport stream that provides a virtual channel m ap to the DTAs (Known as SCTE 65 tables), and/or provides code updated to the DTA’s (in a form at know n as DSM-CC) so that they can be updated through the QAM channel transport stream. The

choices are DISABLED, MASTER (SC TE-18), SLAVE and DEMOD A.. DTA MODE : This menu choice allow s the user to activate or deactivate DTA m ode. The choices are ENABLE and DISABLE. This

option w ill only be available w hen SLAVE is selected under DTA/EAS CONTROL m enu.

If D TA MODE is ENABLED, then an ASII m odule m ust be present in the Master EH24A / EH244 / EH244-IP to receive the ASI stream from your PC. W hether it is plugged into Module 5 or Module 6 slot depends on w hether the SDE24EAS is

also required in the system or not. All units at the headend are then daisy-chained through ASI connections. The Master unit’s ASI OU TPU T connector goes to the ASI INPU T connector of the ASII m odule in the first Slave unit. The AS I LOOP output connector of the ASII m odule in the first Slave unit goes to the ASI INPUT connector of the ASI m odule in the next Slave unit. These ASI LOOPs continue through all Slave units (MEQ1000As, EH24As, EH244s, and EH244-IPs) at the headend. There can be standard SDE24s in some or all of the rem aining slots of the Master unit. If they are w anted to be sent out on the ASI output of the Master unit, these stream s can be picked up from the ASI LOOP output connector of the ASII m odule of the last Slave unit in the chain.

VERY IMPORTANT: When the SDE24EAS is used in s lot 6 of the Master unit, both enc oders in the SDE24EAS must be set to the lowest encoding bitr ate of any other SDE24 in the entire s ystem. This is the only way to m ake sure that when the SDE24EAS’ stream replaces the original streams that it will still fit into all the QAM channe ls.

EAS MODE : EAS Control is provided by 1 of 2 m ethods:

Method 1 - By using the SDE24EAS m odule in a “Master” EAS unit (EH24A / EH244 / EH244-IP, but not the MEQ1000A)

as m entioned above. This m odule has only a single composite input instead of the 2 inputs of a standard SDE24. It is fed by an external EAS Controller source, that then is encoded by both encoders in the SDE24EAS. W hen EAS is activated, the transport stream generated by the SDE24EAS is routed internally in the Master unit and replaces the transport stream s com ing from the other plugged in SDE24s. This w ay all MPEG programs coming out of the Master unit have the EAS video and audio on them . Note that w hen using this method only one SDE24EAS is required per headend, and is placed into the Module 6 slot on the rear of the Master EH24A / EH244 / EH244-IP. The MEQ1000A will need to be

placed in the SLAVE setting.

For Instructions on how to set EAS parameters (inc luding: E AS MODE, EAS RF CH AN NEL, EAS MODULATION, EAS MPEG PROGRAM #, EAS MAJOR CH ANNEL, and EAS MINOR CH ANNEL), ple ase see instruction m anual for the Dr ake Product being used as the E AS MASTER UNIT in your headend (EH24 A / EH244 / EH244-IP).

DEMOD A MODE :

Method 2 - By using the new er digital standard for EAS (know n as SCTE 18). In this m ode, rather than each MPEG

program being replaced by the EAS video, instead w hen the EAS is activated, a table is inserted into the transport stream . This table tells any SCTE 18 capable unit w hich RF channel to switch to and w hich MPEG program number to begin decoding. The receiving unit then sw itches to that program to display the EAS video and audio. W hen the EAS is deactivated, the receiving unit returns to its original channel.

Allows using DTA/EAS tables w hile using the MEQ1000A in a drop/add configuration. In order for the DTA/EAS tables received in the drop/add configuration to be utilized, the DTD1000 m ust be tuned to an RF channel from the Head

End that contains the desired tables. Otherwise the tables on the PID’s w ould be missing because they are not

associated w ith an actual program in the transport stream .

Page 15

Additional Information (Continued) 15

ADDITIONAL CONSIDERAT IONS

STANDBY MODE

The MEQ1000A has a standby output m ode w hich turns off the RF output. This can be used w hen it is desirable to tem porarily disable the output w ithout unplugging the AC line cord. Select STANDBY in the OUTPU T FOR MAT m enu.

OVER TEMPERATURE SENSOR Tem perature m onitoring is built into these products. If the ventilation slots or fan output opening are blocked or the fan should stop,

overheating can occur. If this condition is detected, the default LCD message w ill change to OVER TEMP. If this occurs, the prob- lem should be corrected as soon as possible. The unit w ill rem ain operational but the ventilation m ust be restored to prevent pre- m ature part failures due to overheating.

STATUS DISPLAYS W hen the units are not in the adjust/program m ode, status displays are show n. These vary by input m odule:

DTD1000 Digital Tuner and Dem odulator Module - shows DEMOD SNRs. ASII ASI Input Module - shows ASI data presence.

Pushing the UP arrow button will cause the firmw are version num ber to display. Pressing the DOW N arrow w ill cause the percentage of buffer capacity that is currently in use on the left side of the display and the m aximum percentage of buffer capacity that has occurred since the unit w as last programmed on the right side, for the QAM output selected.

REMOTE CONTROL AND MONITORIN G The MEQ1000A m ay be used w ith the 'Drake Digital Headend Rem ote Control Softw are' program to allow rem ote m onitoring or control.

Only version 2.10.0 or new er is com patible w ith the MEQ1000A. If an SDE24 m odule is installed the Drake Digital Headend Rem ote Control Softw are version m ust be version 3.1.2 or above.

Connect the RS232 cable com ing from the PC or m odem to the RS232 IN DB9 rear panel connector. Assign a UNIT ID (1 to 63) to use the remote program . Leave at, or set to, 0 if no rem ote access is desired. Set the RS232 BAUD RATE to m atch the PC setting.

If you are fam iliar with the program , operation will be clear. If not fam iliar with it, see further instructions in the insert provided with the CD-ROM or stored on the CD-ROM.

The MEQ1000A m ay also be used w ith the SCTeci to provide w ebpage control over a netw ork using an Ethernet connection to the SCTeci. For control of the MEQ1000A, the SCTeci m ust have version 5.0 or new er firmw are.
