2470-HD Time Delay
Introduction
360 Systems 2470-HD Time Delay is a high-quality program delay for television broadcast,
satellite delivery, and other applications requiring a user-settable delay time for video, audio, and
ancillary data. Applications for the delay include:
•Compensation for time zone differences, where a program is received at a different time than
when it needs to air.
•Program origination delays, where content is time-shifted prior to transmission or distribution.
•“+1” channels that allow cable casters to offer multiple feeds of the same program content to
maximize channel exposure with limited additional cost. Viewers can choose to see a variety
of different shows in their chosen viewing time, or see an immediate repeat of a show that
interested them simply by changing the channel.
•The 2570-HD-EX model can be used in a disaster recovery system where a 24 hour delay
provides a guarantee of airing appropriate content for the time of day.
The can be thought of as a black box that records video, audio, and specific ancillary data
information; it then delays the playback of the program by a user-selectable time period. Whatever
goes in, comes out later.
The Time Delay will operate as a set-and-forget box with no user intervention. On restarting after
a power failure, it will again start delaying the input according to the most recent user settings. The
delay time is user-programmable from 6 seconds to greater than 24 hours. The programmed delay
interval is frame-accurate over an indefinite time period; if several Time Delays are fed identical
input signals, they will remain in sync indefinitely.
The Time Delay employs high quality, visually lossless JPEG 2000 video encoding at 100 Mb/s.
JPEG 2000 is an ideal codec for this application, providing superior final image quality when used
in conjunction with other codec processes such as MPEG or H.264 for satellite transmission and
cable distribution.
16 embedded audio channels are provided. Alternately, two +4 dBu analog channels are
available. Audio I/O is on chassis-mounted gold-plated XLR-3 connectors. Available options allow
for 8 channels of AES/EBU.
ATC Time Code is reproduced, as well as up to 12 selectable lines of Vertical Interval Ancillary
(VANC) data. (In 1080i 6 lines from field 1 are selected, and the corresponding lines in field 2 are
automatically selected.)

9Warranty Card
The Time Delay is not shipped with a video monitor. Select a VESA-compliant CRT or LCD monitor
capable of a refresh rate of at least 75 Hz. Note that the Time Delay may not start correctly if an
unsuitable monitor is connected.
If you own more than one Time Delay, it may be appropriate to use a single keyboard, monitor, and
mouse with a KVM switch to select between units. Not all KVM switching systems are compatible.
The KVM switch must supply an active signal to the Time Delay at all times, even when switched away
from it. When first powering up the Time Delay, use only the supplied keyboard and mouse directly
connected. Then test the KVM switch system that will be used thoroughly before installation is
completed. NOTE: If the mouse and keyboard connections are interchanged, the Time Delay may not
boot up properly. Be especially careful about this when using extender cables.
Rack Mounting
There are four adhesive-backed rubber feet on the Time Delay. These may need to be removed
when rack mounting the unit.
Cables attached to the rear of the Time Delay should be supported by the rack mounting rails. Do
not support substantial cable weight from the Time Delay.
Remove the front panel to expose the rack screw slots. Fasten the Time Delay into the rack.
Replace the front panel. Tighten the front panel access screws.

Introduction & Features 9
Important Installation Notes
System Cooling
When many pieces of equipment are mounted in an equipment rack, a considerable amount of heat
may be produced, which must be removed efficiently. Further, a lower operating temperature will
make equipment operate more reliably, and it will last longer. In the extreme case, excessive
temperatures cause rapid equipment failure, and damage which can be difficult to repair.
Heat in an equipment rack should be removed by forced air. This is often accomplished by blowers
installed in the top of the rack, venting into the room. An alternative is to draw hot air from the top
of the rack into an air-conditioning return duct, and not vent it into the equipment room; cold air
should be ducted into the bottom of the rack.
The optimum air temperature for cooling electronic equipment is 25° C (72° F). When many
pieces of equipment are contributing to the heat load, a substantial air-flow will be needed, and the
inlet temperature may need to be lower.
Check These Points
•Are all ventilation holes in the Time Delay free of obstruction?
•Can blowers or HVAC system adequately remove heat from the equipment rack?
•Have you measured the actual temperature inside the rack? Do this near the top.
•Verify that the HVAC system is not on a timer that can shut off on weekends or holidays.
•What procedures are in place to protect the equipment when the HVAC system fails?
Power Conditioning
It is good practice to operate an on-air video Time Delay from an Uninterruptible Power Source, or
UPS. All utility power systems experience occasional transient events, including brownouts and
dropouts, which are capable of taking the Time Delay off the air. It is the station operator’s job to
plan for and overcome such contingencies.
UPS units suitable for smoothing short-term power line problems come in two varieties:
Change-over UPS Design
This design senses drop-outs and low line voltage, and switches its output to an internal inverter
operating from a battery. This UPS is low in cost, and is most often used in non-critical applications
such as desk-top computers. A disadvantage is that it may create its own power transients when
switching between utility power and its inverter supply. For this reason 360 Systems does not
recommend this type for use with the Time Delay.
Continuous Conversion UPS Design
This improved design continuously converts utility power to DC, stores it in a battery, then
produces isolated AC power from an inverter. It never switches, and is immune to input transients,
brownouts, and blackouts. Models are available with batteries of almost any size, making the
continuous-conversion UPS suitable for transient suppression or long-term operating power in the
absence of utility power.

10 •2470HD Time Delay
Recommended UPS Models
The following makes of continuous conversion UPS systems are suitable for use with 360 Systems’
video products:
APC Smart-UPS 2200-XL
Eaton/Powerware Corporation, Model 9125, www.powerware.com
This unit is available in several different configurations to accommodate various current load and
power failure support times.
The minimum requirement for maximum current load for a single Time Delay is 2 amps.
Operating Environment
A Time Delay is a critical element in broadcast operations. Its installation should safeguard it from
every external event that can interfere with it doing the task expected of it. 360 Systems’ engineers
have experience with thousands of installations, and have become aware of a number of
environmental factors that can adversely affect performance. Two of these have already been
discussed: power conditioning and inadequate cooling. Two others, less obvious, should also be
considered:
RF Interference by Cell Phones
Many people are not aware that cell phones can attain a very substantial power output, even when
no conversation is taking place. You may have experienced the effect of a cell phone interfering
with a common desk phone placed nearby. Carrying a cell phone into a machine room where it is
in close proximity to broadcast equipment and its associated wiring is unwise. They are able to
interfere with serial control commands, video synchronization, and in some cases can crash the
CPU in equipment.
Some major broadcasters prohibit the carrying of cell phones into certain machine areas. 360
Systems believes that the risk of undesired equipment behavior from their RF fields is very real.
Static Discharge
Static electricity discharge is accepted by most people as an inevitable consequence of living in a
dry area. It is, rather, a result of floor coverings that may enhance appearances, but are
inappropriate for use around critical pieces of broadcast equipment. Static discharge can do two
adverse things:
•Discharge into a connector can—and will—destroy internal circuitry of equipment. The result
will always be difficult to diagnose and repair.
•Discharge to equipment frames or wiring can crash a CPU and take the station off the air. The
event may seem random or unrelated to static, but it is clearly a catastrophic event—and one
that can repeat indefinitely as humidity varies.

Introduction & Features 11
Several steps can be taken to protect equipment from static discharge:
•Do not install critical broadcast equipment in a room with carpeting.
•Connect equipment racks directly to an earth ground with a heavy copper conductor.
•Do not operate equipment with a lifted safety ground (green frame ground).
•Install a humidifier, if necessary, to reduce the likelihood of static discharge.
About Time Delay Software
The Time Delay is shipped with its application programs and operating system installed.
The first time that it is started, it must be connected to a keyboard, monitor and mouse. The Time
Delay will ask you to accept the Software Licensing Agreement before it will operate. This screen
will only appear during the initial startup.
If for any reason it becomes necessary to reinstall any software, refer to the Software / Firmware
updates chapter on page 34 and 35 for instructions.

Front Panel Features
Reset button
The recessed Reset button initiates start-up and shut-down of the 2470-HD Time Delay. Verify that the
rear panel power switch is on, then press Reset momentarily to start the Time Delay. A sequence of
start-up screens will appear, ending with the graphic user interface.
When the Time Delay is running, pressing the Reset button momentarily will cause the system to begin
an orderly shutdown. This can also be initiated from the GUI by selecting
START > SHUTDOWN > SHUTDOWN. In most cases the power will shut off automatically,
however if the front panel lights begin to blink, the file system has been properly closed and it is safe to
force the power off by holding the front panel button in for 4 seconds.
In the event that the system has stopped responding to commands and will not shutdown, hold the
button in for 4 seconds to force a power down.
Do not use the rear panel switch on the power supply to shut down the Time Delay. Abrupt power loss
can cause loss of information stored on the disk array. The rear panel power switch can be used to
prevent re-application of power during service procedures once the normal shut down sequence is
complete.
CAUTION:
LOSS OF DATA CAN OCCUR IF THE POWER IS TURNED OFF WITHOUT A SHUTDOWN.
USE THE FOUR SECOND SHUTDOWN ONLY IF THE SYSTEM IS NOT RESPONDING OR THE
SHUTDOWN PROCESS DOES NOT TURN THE POWER OFF AUTOMATICALLY.
Indicators
Five blue LED Status Indicators appear on the front panel. These indicators are illuminated
continuously or in some cases are dark when the system is functioning normally. Error conditions are
indicated by flashing. See the table Front Panel Indicators on page 37 for diagnostic meanings.
The Status Indicators are also available as GPI outputs, along with an additional output warning for loss
of input. See GPI connector on page 29 for details.

The Time Delay provides one video input with up to 16 Embedded audio channels, one
delayed video output with audio, and a second monitoring output which reflects input video and
audio (E-E).
Additionally, there are two analog audio inputs that can be used instead of embedded
audio. These correspond to audio channels 1 and 2, and appear in the embedded audio on the
video outputs and the XLR outputs. The XLR audio outputs will also carry audio channels 1 and 2
when embedded audio is selected as the input source.
The HDMI outputs carry audio channels 1 and 2 when either embedded or analog audio is
selected. Audio from other channels cannot be output by either Analog or HDMI audio.

Operations 15
Operations
The Graphical User Interface
The Time Delay uses a Graphic User Interface (GUI) to control most functions. A keyboard
and mouse are included, and the user needs to supply an SVGA monitor—either CRT or flat-panel.
The GUI is divided into two sections: Run/Stop control, and Time Delay Set. Controls and
displays for each section are described below.
In addition, the Menu Bar provides two dialogs, accessed through Configure>Options,
and Help>About.
Graphical User Interface

16 2470HD Time Delay
Run, Stop, Time to Air display
Time Delay Setting and Quick Select Presets
Run/Stop Control
Run
The RUN button initiates or restarts the time delay process. Press RUN to begin a new delay
cycle, and restart the Time-to-Air countdown. When the countdown reaches zero, it changes to
ON LINE, and the delayed video begins playing from the main Program Output.
Upon power up the Time Delay will automatically enter Run mode and start the delay
process if a valid input is detected..
Stop
The STOP button stops playout and clears stored program content from memory. Note that
the Time Delay value can only be changed when the machine is in the STOP mode.
Time to Air
Initially, the Time to Air display shows the selected Time Delay Setting. Once RUN is
pressed and the recording process sets up and commences, Time to Air is a countdown value,
displaying the time remaining before delayed program material reaches the output. It is an
approximate display value; it is not directly locked to the video timing.
Time Delay Setting
Delay time is entered and displayed in the DELAY TIME window in HH:MM:SS:FF format.
(Hours:Minutes:Seconds:Frames) The desired time is entered from the keyboard from left-to-right.
Delay times may also be entered as whole units of seconds, minutes, hours, by appending
a suffix, (s, m, or h) to the value entered into the text box, such as “120m” or “30s.” In the 2470-
HD-EX “1d’ will set a 24 hour delay.
A Note about Maximum Delay Time
360 Systems manufactures two distinctly different models of Time Delay, the 2470-HD having at
least 8 hours and the 2470-HD-EX having at least 24 hours of delay. Intended usage is for delays
up to 8 and 24 hours respectively. Actual maximum available delay time may vary depending on
video format and the specifics of current system design and configuration. The units are not
designed or intended to be upgradeable for greater delay times.

Operations 17
Delay Hours Quick Select
Six preset buttons provide a rapid way to set a delay time to an even number of hours from
1 to 6. With the machine stopped, clicking on one of these buttons will immediately load that time
value, expressed in hours. An appropriate number of zeros will also be entered for MM:SS:FF. The
presets are not active while the machine is running.
Configure Options Dialog
Configure Options Dialog
Main Screen Title
This allows a user selected title to replace the default “Time Delay” in the title bar of the main GUI
window.

18 2470HD Time Delay
Video Mode
Four radio buttons select the Video Mode, which includes the frame rate and video format. These are:
59.94 Hz / 720p
59.94 Hz / 1080i
50 Hz / 720p
50 Hz / 1080i
This setting can only be changed when the Time Delay is stopped. When it is changed, the
unit will display a warning and then automatically perform a quick restart to initialize in the newly
selected mode.
Audio Input Source
Three radio buttons select the input source for audio. These are:
SDI Embedded Audio
AES Digital Audio (when optional DXP-5 interface is connected)
Analog Audio
The Analog audio inputs are the pair of +4 dBu analog XLR inputs on the rear panel.
This setting can only be changed when the Time Delay is stopped.
Regardless of the input selected, audio will always appear in parallel, both in the
embedded audio HD-SDI stream, the analog XLR outputs and the optional DXP-5 AES/EBU
outputs. The input selection affects how many channels are available. With Analog, channels 1
and 2 are active and channels 3-16 will carry silence on embedded audio and AES/EBU outputs.
With AES/EBU selected, channels 9-16 of the embedded audio output will carry silence.
The 2470-HD Time Delay supports embedded audio in groups 1-4, which includes Audio
Channels 1-16, providing 24-bit,
48 KHz, synchronous audio, as per SMPTE 299M.

Operations 19
VANC Line Selection
This field accepts either a comma separated list of
specific line numbers, or the limits of a range separated by a
hyphen as shown here.
•In 720p operation, up to 12 lines can be specified. Valid line numbers are in the
range of 1 to 25.
•In 1080i operation, up to 6 lines can be selected from field 1; the corresponding
lines in field 2 will automatically be recorded. Valid line numbers in 1080i are in
the range of 1 to 20.
Output Timing
This controls the timing relationship of the output to the
reference, which is the input video. (The GENLOCK input is not active
and is reserved for future use.)
Note that these timing adjustments apply only to the Delay
output, not the Monitor output. The monitor outputs are designed
for confidence monitoring only, and are not timed.
In most applications these adjustments are not necessary. They are only used in
environments where the output must be adjusted to match other timed equipment, for example
when using a switcher or video mixer that requires precise timing alignment.
Both adjustments are made by using numeric entry from the keyboard or the Up and Down
Arrow buttons next to the parameter’s numeric display.
The Output Timing values are the only parameters that are adjustable while the Time Delay
is in RUN to allow timing while in operation. Adjustments take effect immediately without using
Apply or OK, allowing the effects to be seen easily. The picture will blank while the change takes
effect.
Vertical (Lines)
Adjusts the output line timing in relation to the reference, by an amount equal to one complete
line. The adjustment range is -4 to +30 lines.
Horizontal (nsec)
Adjusts the output line timing in relation to the reference, by an amount equal to one half pixel.
The adjustment range is ±100,000.
The Up/Down Arrow buttons increment in steps of 10 nsec.

20 2470HD Time Delay
Configure Network
Network parameters are set in the Configure Network dialog. Network communication for
the Time Delay is designed primarily to support access to error logs and factory diagnostics. It can
also support automatic time updates using the NTP protocol. The system time is used only in the
diagnostic system message logs, it does not affect the operation of the Time Delay in any way.
Use only the NET1 connection on the rear panel to connect to the network. Make no
connection to NET2.
Configure Network dialog
Use the Configure Network dialog to configure network communication settings.
From the Main Menu selection bar at the top of the screen, select Setup>Options, then in
the window on the left select Network.
Each Time Delay is shipped with a unique default network Host Name and IP Address.
Qualified network engineers may change these configurations to suit your specific network
environment. Factory defaults for networking are:
•Disable Network is checked
•Use DHCP is unchecked
Disable Network Checkbox
This selection turns the network off or on. The default is Disable.
