e Tektronix ECO422D SD/HD Changeover Units and video sync

pulse and signal generators are to be deployed.

Changeover unit models

This manual describes how to integrate a system using a Tektronix

Stay GenLock

®

Stay GenLock

®

is a digital genlock technology developed by Tektronix for the

signal generators covered by this manual. It provides additional robustness and

stability for genlocked SPGs, as in a master/slave conﬁguration. (See page 103,

Using Stay GenLock

®

.)

Suppo

rted products

The information in this manual covers the Tektronix products described below.

ECO422D SD/HD

Changeover Unit

The ECO422D is a highly versatile sync changeover unit designed for use in a

serial SD/HD digital television environment. The ECO422D will accommodate

component or composite serial digital video signals, AES/EBU digital audio,

tri-level sync, and analog black-burst signals. This ﬂexibility makes the ECO422D

id

eal for both the mixed-format and all-digital television facility.

The ECO422D provides eleven user-conﬁgured channels, each channel consisting

o

f primary and backup i nputs, and an output. These channels can be set as follows:

Six channels can be set for high-deﬁnition serial digital video,

standard-deﬁnition serial digital video, AES/EBU digital audio, tri-level sync,

and PAL or NTSC analog black burst

Five channels may be set for standard-deﬁnition serial digital video,

AES/EBU digital audio, tri-level sync, and PAL or NTSC analog black burst

Channel conﬁguration is by internal DIP switch. The signal amplitude fault

detection level follows the setting of the channel conﬁguration switches. Detection

on individual channels may be disabled, giving the option of disabling changes to

the backup unit o n failure of signals not critical to the facility operation.

Video Sync Pulse Generator and ECO422D SD/HD Changeover Unit System Integration xi

Preface

When operated i

n the switch-on-fault mode, the ECO422D will automatically

select the backup sync source should any of the primary inputs fail. However, in

the u nlikely event both sync sources are faulty, the ECO422D will not alternate

between the two sources. If necessary, this function may be overridden with the

manual sync source selection. Manual source selection also facilitates periodic

testing of the changeover function. Switching is by mechanical relay with all

channels sw

itched simultaneously.

The Electrical Fast Switch function, available with Opt. ELSW, improves the

changeove

r switching s pe ed between inputs, and rep laces the mechanical relay on

channels 4-6. Using this type of switch minimizes disturbance when switching

between primary and backup inputs. With Option ELSW, channels 4-6 can accept

only a blac k-burst or tri-level sync signal.

Front-panel controls are provided for source selection, operating mode, resetting

the fault indicators, and for disabling the front-panel controls. LED indicators

are also provided. Indication of fault and unit on line is also available through

the remote c onnector.

SPG600

/300 Sync Pulse

Generators

The SPG600 and SPG300 Sync Pulse Generators provide synchronization and

test signals for both traditional analog and mixed d igital and analog facilities, in

both NTSC/525 and PAL/625 environments. These products are ideal as a stable

mast

er sync signal, which is critical in digital broadcast environments.

When these instruments are conﬁgured for Stay GenLock mode, a m omentary loss

of s

ynchronization at the genlock reference input will not cause a disturbance in

the test signal and black outputs of the unit. When the genlock signal is reapplied,

the SPG system will gradually reacquire lock. This will cause little disruption in

the outputs of the device and will not cause any noticeable glitches in the outputs

of the SPG.

The Genlock source can be NTSC/PAL Black Burst, NTSC/PAL Sync , or CW.

When using CW lock, the Genlock timing can be adjusted on all the NTSC or

PAL color frames.

Preface

SPG8000 Master Sync /

Clock Reference Generator

The SPG8000 is a

precision multi-format video signal generator, suitable for

master synchronization and reference applications. It provides multiple video

reference signals, such as black burst, HD tri-level sync, and serial digital and

composite analog test patterns, and it provides time reference signals such as time

code and NTP (Network Time Protocol).

Thebaseconﬁguration includes three sync outputs that can be conﬁgured with

independent output formats (NTSC/PAL black burst and/or HD tri-level sync)

and independently adjustable timing offsets. With the BG option, four more

analog out

puts can be added. A high-accuracy, oven-controlled crystal oscillator

provides a stable frequency reference for the system, or the pass-through genlock

input c an be used to lock to an external video reference or 10 MHz continuous

wave signal. The SPG8000’s Stay GenLock

®

feature avoids “synchronization

shock” if the external reference suffers a temporary disturbance, by maintaining

the frequency and phase of each output signal. When the external reference is

restore

d, Stay GenLock

®

ensures that any accumulated clock drift is removed by

slowly adjusting the system clock within standard limits instead of “jamming”

back to the correct phase.

Time reference outputs are available in multiple formats. Three independent

linear time code (LTC) outputs are available, and a fourth LTC connection can be

used as input or output. Each LTC output has independent frame rate selection,

time source (time-of-day or program time) and time zone offset. Vertical

interval time code (VITC) is available on each NTSC or PAL black output, also

with

independent time sources and offsets. The SPG8000 can also serve as a

Network Time Protocol (NTP) server, providing the time-of-day reference to

network-attached devices.

Optional GPS Receiver. The GPS option adds an internal GPS receiver to the

SPG8000. When connected to a n external antenna that supplies the standard GPS

R

F signal, the SPG8000 can utilize the GPS system’s stable frequency reference.

The GPS signal also includes a precise time-of-day reference that can be used for

all time code outputs. Similar to the Stay GenLock

®

feature, the SPG8000 can

maintain the video frequency and phase when the GPS signal is interrupted, and

the Holdover Recovery mode will ensure a shock-free re-alignment of frequency

and phase when the GPS signal is restored.

Preface

TG700 and TG8000

Multiformat Test Signal

Generators

The TG700 and TG

8000 are multiformat, analog and digital, precision signal

generation platforms. Designed with the changing needs of the video industry in

mind, the they offer sync pulse generation and test signal generation for a wide

array o f analog, serial digital, and digital high-deﬁnition formats.

The instruments have a modular architecture that offers the ﬂexibility to meet the

single-format and growing multiformat needs of the video professional. They

allow up to four of the following modules to be ﬁtted in the mainframe.

AGL7 modul

e. The TG700 and TG8000 have a high stability reference. The

AGL7 Analog Genlock Module adds the capacity to lock to a variety of signals,

whichmakestheTG700andTG8000idealsolutions as the master house reference

or slave reference for broadcast and production/post-production applications.

Three black outputs are available and are selectable for HDTV tri- level or NTSC

or PAL. Additionally, the AGL7 can lock to a variety of formats to include

NTSC/PAL black and HDTV tri-level as well as 1, 3.58, 4.43, 5, and 10 MHz CW.

WhentheAGL7isconﬁgured for Stay GenLock

®

mode, a momentary loss of

synchronization at the genlock reference input will not cause a disturbance in the

test signal and black outputs. When the genlock signal is reapplied, the AGL7 will

gradu

ally reacquire lock, causing little or no disruption to devices synchronized

to the reference.

GPS7 module. The GPS7 GPS Synchronization and Time Code Module includes

an integrated GPS receiver which can serve as the system timing reference.

Synchronization to the GPS timing signals ensures long-term stability, and video

fra

me alignment between independent systems. The GPS RF coaxial signal input

is available with 3.3 V or 5 V DC power output for the GPS antenna enabling the

user to select from a variety of GPS antennas available on the market.

The GPS7 also includes a genlock input with VITC reader, enabling

user-selectable conﬁguration of the TG700 and TG8000 as the master reference

or as a slave to another m aster, depending on the dynamic requirements of each

production. The GPS7 module will maintain system timing by Stay GenLock

®

technology even during periods of GPS signal loss or genlock signal loss. Three

black outputs are available and a re selectable for HDTV tri-level, NTSC, or PAL.

Time code source can be selectable to the time-of-day (with user-selectable

offsets) from GPS receiver, internal source, VITC on the reference input, LTC

input, or to a " program time" counter for elapsed-time time code. The Daylight

Savings Time (DST) adjustment could be recurring scheduled, based on calendar

rules. Time code is available as VITC on black outputs (GPS7, BG7), as Ancillary

Time Code (ATC) (HDVG7, HD3G7), from four independent LTC outputs

(GPS7), and as a response to time requests on a Simple Network Time Protocol

(SNTP version 3.0) Server.

HDLG7 module. T

he HDLG7 is a test signal generator that p rovides two identical

dual-link high-deﬁnition serial digital interface (HD SDI) outputs. The module

supports video formats that require the use of a dual-link interface, such as 4 :4:4

R'G'B' at rates up to 1080i/60 Hz or 1080p/30 Hz, or 4:2:2: Y'C'bC'r at rates up to

1080p/60 Hz. The HDLG7 supports several standard test signals, and a lso has

the unique ability to up-convert an arbitrary single-link HD-SDI input signal to

a dual-link

format for the outputs. The HDLG7 also supports digital cinema

2K formats and test patterns.

HD3G7 module. The HD3G7 is a test signal generator that provides two outputs

of a HD/3G-SDI video test signal. 720-line formats and 1080-line formats

described in SMPTE standards a re supported for both Level A and Level B

mapping s

tructures, including 4:4:4 and/or 12-bit sampling, Y'C'bC'r, R'G'B', or

XYZ color space, and 2K digital cinema formats. The 2×SMPTE 292M HD-SDI

format used by some 3D TV applications is also supported.

The HD3G7 can generate up to 32 channels of 24-bit 48 kHz embe dded audio,

with independently set frequency and amplitude for each channel. The HD3G7

also has the ability to generate other types of ancillary data, such as video payload

identiﬁer, ancillary time code, and user-deﬁned packets.

The HD3G7 includes a wide variety of standard test signals, including SMPTE

color bars, pathological test patterns, and a programmable moving zone plate

pattern, and it also has the ability to up-convert an input 1 .485 Gb/s HD-SDI

sign

al to a 3G output. The HD3G7 has a clock/frame trigger output that can be

used to synchronize the output with an oscilloscope, for example.

SDI7 module. The SDI7 is a test signal generator that provides two independent

channels of SD/HD/3G-SDI video test signalgenerationinavarietyofformats

with two outputs for test and test/black signal generation per channel (3G-SDI

s

ignal generation is available as an option).

The SDI7 can generate up to 32 channels of 24-bit 48 kHz embedded audio, with

i

ndependently set frequency and amplitude for each channel. The SDI7 also

has the ability to generate other types of ancillary data, such as video payload

identiﬁer, ancillary time code, and user-deﬁned packets.

The SDI7 includes a wide variety of standard test signals, including SMPTE color

bars, patholo gical test patterns, and a programmable moving zone plate pattern,

and it also has the ability to generate full frame test signals created by the user.

AV timing signal generation, when used in conjunction with a waveform monitor,

can be used to ensure that audio and video are synchronized through a video

path. Circle, multi-language text, and color logo overlays may be applied to the

generated test signals to check aspect ratio, identify streams, o r apply station

logos. The clock/frame trigger output can be used to trigger an oscilloscope to

be synchronous with the video output.
