Revision 1.5 7721DE-1
1. OVERVIEW
The 7721DE SDI data embedder inserts an RS-232/422 serial data stream and GPI contact closure
information into a 270 Mb/s SDI video signal. The RS-232/422 serial data and GPI information are first
formatted into an AES audio signal, then embedded into the video stream according to SMPTE 272M-A
specification. A data error detection and correction scheme is also applied to maintain data integrity for
the data de-embedder at the receiver end. At the embedded packet layer, data packets resemble and
have the same group DIDs as embedded audio packets.
Features:
•Automatic detection of 525 and 625 line SDI video input
•Automatic activation of internal 525 or 625 line black video generation at the loss of video input
•One RS232/422 serial input with selectable baud rate (9600, 14,400, 19,200, 38,400 or 57,600)
•Parity selection: none, even or odd
•Support serial input with BREAK character according to SMPTE 207M
•Packetize data into the sub-frame AES format according to SMPTE 337M
•Embedding mechanism based on SMPTE 272M-A
•Share the same group DIDs as for embedded audio, selectable from group 1 to 4
•Channel selection for mapping data into one of four channels within a group
•Redundant data transmission to allow data error detection and correction at the receiver end
•Automatically remove the existing embedded packets when the conflict of group DID occurs
•Remove packets with "Marked packets for deletion" and "Data end marker packet"
•Six TTL level GPI inputs to embed simple control information into the video input
•EDH generation on video output
•Card edge LEDs indicate video signal and data presence, cable equalization and module fault

The GPIs are active low with an internal pull up (4.7k Ohm) resistor to the Vext pin. The user can connect
GP+5V supplied from the module into the Vext pin to provide power to the GPI opto-isolator circuitry. In
this configuration the user can activate GPIs simply by connecting the GPI input pins to Ground (refer to
Figure 2-2). This can be done with a button, switch, relay or an open collector transistor. Five volts is
available to the user to be used for driving external circuitry. Care must be taken to limit the load to 0.5W
so there is no affect on the power supply source on the module. The GPI information is embedded into
the data stream and will activate the corresponding GPO outputs on the 7721DD Data De-embedder.
They can be used to pass simple contact closure information along with the video signal. Alternately, the
user can connect an external power source for the opto-isolator circuitry. The Vext voltage must be
greater than the voltage supplied to GPI by at least 5v. Figure 2-3 shows how to wire the GPIs from an
external power supply.

6.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
FRAME STATUS: The FRAME STATUS jumper located at the front of the module determines whether
local faults (as shown by the Local Fault indicator) will be connected to the 7700FR
frame's global status bus.
To monitor faults on this module with the frame status indicators (on the PS FRAME
STATUS LED's and on the Frame's Fault Tally output) install this jumper in the On
position. (Default)
When this jumper is installed in the Off position, local faults on this module will not
be monitored.
6.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE: The UPGRADE jumper J16 located at the front of the module is used when firmware
upgrades are being done to the module. For normal operation it should be installed
in the RUN position. See the Upgrading Firmware section of this manual for more
information.
To upgrade the firmware in the module unit pull it out of the frame. Move Jumper
J16 into the UPGRADE position. Install the Upgrade cable provided (located in the
vinyl pouch in the front of this manual) onto header J24 at the card edge. Re-install
the module into the frame. Run the upgrade as described in the Upgrading
Firmware section of this manual. Once the upgrade is completed, remove the
module from the frame, move J16 into the RUN position, remove the upgrade cable
and re-install the module. The module is now ready for normal operation.

Revision 1.5 7721DE-11
6.3. CONFIGURING THE SERIAL PORT FOR RS 232 OR RS 422 OPERATION
J17: Jumper J17 located at the side of the module is used to select whether the serial
port receiver/driver hardware is configured for balanced RS422 or RS232 with flow
control. For RS 422 operation install jumper J17. For RS 232 operation remove
jumper J17. For convenience you may re-install the jumper so that only one side is
connected.
6.4. SETTING THE EQUALIZER WARNING THRESHOLD
The Cable Length Warning Adj trimpot located near the Signal Present LED is used to set the threshold of
the cable equalizer warning. The equalizer warning is factory set to 250 meters of Belden 8281 cable, but
may be adjusted for other cable types or cable lengths. To adjust the cable equalizer warning threshold,
connect a signal to the input of the module using the required length of cable. Adjust the trimpot slowly
until the Equalizer warning LED comes on. You can verify that the equalizer warning is operating correctly
by removing a few meters of cable from the input. The LED should go off.

7. VistaLINK®REMOTE MONITORING/CONTROL
7.1. What is VistaLINK®?
VistaLINK®is Evertz’s remote monitoring and configuration platform which operates over an Ethernet
network using Simple Network Management Protocol (SNMP). SNMP is a standard computer network
protocol that enables different devices sharing the same network to communicate with each other.
VistaLINK®provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK®PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK®enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
There are 3 components of SNMP:
1. An SNMP manager, also known as a Network Management System (NMS), is a computer running
special software that communicates with the devices in the network. Evertz VistaLINK®Pro Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK®enabled products.
2. Managed devices (such as the frame synchronizers), each with a unique address (OID), communicate
with the NMS through an SNMP Agent. Evertz VistaLINK®enabled 7700 series modules reside in the
3RU 7700FR-C MultiFrame and communicate with the manager via the 7700FC VistaLINK®frame
controller module, which serves as the Agent.
3. A virtual database known as the Management Information Base (MIB) lists all the variables being
monitored, which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK®network, see the 7700FC Frame
Controller chapter.

7.2. VistaLINK®CONTROLLED PARAMETERS
SCTE 104 Settings
Reserved This parameter is a fixed value and cannot be modified. The reserved parameter is two-byte field and is fixed to a value of 0xFFFF. It will be
inserted as the first word in the SCTE 104 packet.
messsageSize
The messageSize parameter defines the size of the entire
single_operation_message() structure in bytes. This parameter is a
read-only parameter and the 7746FSE-GPI-HD+SCTE104 generates its
value internally and dynamically.
protocol_version
The protocol_version is an 8-bit unsigned integer field whose function is
to allow, in the future, this message type to carry parameters that may
be structured differently than those defined in the current SCTE 104
protocol. It shall be zero (0x00). Non-zero values of protocol_version
may be used by future versions of the SCTE 104 standard to indicate
structurally different messages. This parameter is a fixed value and
cannot be modified.
AS_Index
The AS_index uniquely identifies the source of the message (since it is
possible to have several automation systems active at once). The
number ranges from 0 to 255 and shall be zero if this index is not
required. If non-zero, AS_index shall be unique within a single digital
compression system.
message_number
The message_number can be any number in the range 0 to 255 and
must be unique for the life of a message. The message_number is used
to identify an individual request. This parameter is a read-only parameter
and the 7746FSE-GPI-HD+SCTE104 generates its value internally and
dynamically. Each time a new message is injected, the message
number will increment.
DPI_PID_index
The DPI_PID_index specifies the index to the DPI PID, which will carry
the splice_info_sections. The number ranges from 0 to 65535.
DPI_PID_index shall be zero if not required by the system architecture.
This two-byte control is defined as a text entry box with a maximum
possible value of 65535.
SCTE35_protocol_version
An 8-bit unsigned integer field whose function is to allow, in the future,
this message type to carry parameters that may be structured differently
than those defined in the current protocol. It shall be zero (0x00). Non-
zero values of protocol_version may be used by a future version of the
SCTE 104 standard to indicate structurally different messages. This
parameter is a fixed value and cannot be modified.
Timestamp
This field delivers the exact time to process all of the requests in the
injected message. The time_type field may be zero, indicating the
messages are processed immediately. The 7746FSE-GPI-
HD+SCTE104 injects a fixed value of 0x00, thereby instructing
immediate processing.
num_ops
This field defines an integer value that indicates the number of requests
contained within the data packet. This parameter has a fixed value of
0x01, indicating a single data table embedded in the packet. This data
table is the Splice Request Data table.
opID
The opID is an integer value that indicates what request is being sent.
This parameter is fixed to a value of 0x0101, indicating that the
splice_request_data() table is transmitted. This value is fixed and
cannot be modified.

7700 MultiFrame Manual
7721DE Serial Digital Data Embedder
7721DE-14 Revision 1.5
Data_length The data_length is the size of the data() field being sent in bytes. This parameter is a read-only parameter and the 7746FSE-GPI-
HD+SCTE104 generates its value internally and dynamically.
GPI Mode
The GPI mode defines what state the GPI will be considered active
when triggered. This parameter has two states: Active Low and Active
High. When set to Active Low, the 7746FSE-GPI-HD+SCTE104 will
consider a GPI triggered when the voltage level drops from the internal
+5V to ground. When set to Active High, the 7746FSE-GPI-
HD+SCTE104 will consider a GPI triggered when the voltage level
transitions from ground to +5V.
Upstream Pass Mode
This parameter defines the behaviour of the 7746FSE-GPI-
HD+SCTE104 if SCTE 104 packets detected on the input. This
parameter has two states: Pass Through and Pass Remap. If the value
is set to Pass Through and a SCTE 104 packet is detected on the input,
they are directly passed to the output on the same detected line. If the
value is set to Pass Remap, then the original detected packets are
marked for deletion as per SMPTE 291M and re-inserted onto a new line
defined by the Upstream Line Remap Control.
Upstream Line Remap
This parameter defines which line to re-insert detected SCTE 104
packets. This parameter is only used when the Upstream Pass Mode
parameter is set to a value of Pass Remap and has a valid range from
lines 6 to 29 for both SD-SDI and HD-SDI type signals.
GPI Triggering
This parameter enables and disables the GPI processor. There are 3
possible values; disable, GPI 1, and GPI 2. To completely disengage
the GPI processor set the value of this parameter to disable. When set
to disable, any GPI triggering activity will be ignored. To use GPI 1 as
the SCTE 104 insertion trigger, set this parameter to a value of GPI 1,
and to use GPI 2 as the SCTE 104 insertion trigger, set this parameter
to a value of GPI 2. Upon each successful SCTE 104 insertion the
7746FSE-GPI-HD+SCTE104 will send an SNMP trap alarm and also
illuminate the card edge LED’s for a period of approximately 5 seconds.
DPI Filter
This parameter is used to disable or enable upstream DPI filtering. To
filter out any detected upstream SCTE 104 messages set this value to
enable. To allow upstream SCTE 104 message to pass through the
7746FSE-GPI-HD+SCTE104 module, then set this value to disable.
When set to disable the Upstream Pass Mode will be used to define the
pass through behaviour.
Line Select When inserting SCTE 104 messages, this parameter is used to define the insertion line and has a valid range from lines 6 to 29 for both SD-
SDI and HD-SDI type signals.
Manual DPI Insert
This parameter is used primarily as a test and debug control. When set
to a value of enable, the 7746FSE-GPI-HD+SCTE104 will insert a SCTE
104 message once every 10 seconds. Upon each successful insertion
the 7746FSE-GPI-HD+SCTE104 will send an SNMP trap alarm and also
illuminate the card edge LED’s for a period of approximately 5 seconds.

splice_insert_type
The splice_insert_type parameter is an 8-bit unsigned integer defining
the type of insertion operation desired. This parameter has 5 possible
states: spliceStart_normal, spliceStart_immediate, spliceEnd_normal,
sliceEnd_immediate, and splice_cancel.
Please refer to SCTE 104 for clarification of the inferred values.
spliceStart_normal section(s) occur at least once before a splice point.
This interval should match the requirements of SCTE 35 and serve to set
up the actual insertion. It is recommended that if sufficient pre-roll time
is given by the AS, the Injector sends several succeeding SCTE 35
splice_info_section() sections (per SCTE 35 and SCTE 67) in response
to a single splice_request message with a spliceStart_normal
splice_insert_type value. spliceStart_immediate sections may come
once at the splice point’s exact location. The Injector shall set the
splice_immediate_flag to 1 and the out_of_network_indicator to 1 in the
resulting SCTE 35 splice_info_section() section. Usage of “immediate
mode” signaling is not recommended by SCTE 35 and may result in
inaccurate splices.
spliceEnd_normal sections come to terminate a splice done without a
duration specified.
They may also be sent to ensure a splice has terminated on schedule.
The Injector sets the out_of_network_indicator to 0. If they are to
terminate a spliceStart_normal with no duration specified, they should be
sent prior to the minimum interval before the return point and carry a
value for pre_roll_time, especially if terminating a long form insertion.
spliceEnd_immediate sections come to terminate a current splice before
the splice point, or a splice in process earlier than expected. The Injector
sets the out_of_network_indicator to 0 and the splice_immediate_flag to
1. The value of pre_roll_time is ignored. splice_cancel sections come to
cancel a recently sent spliceStart_normal section. The AS must supply
the correct value of splice_event_id for the section to be cancelled. The
Injector shall set the splice_event_cancel_indicator to 1.
splice_event_source
The splice_event_source is a user assigned number for the source of a
cue message. There are four possible values: 0, 4, 8 and 12. A value of
0 indicates that the source of the cue message is a cue embedded in the
original source material. A value of 4 indicates a cue created by
automation system switching. A value of 8 defines a cue created by a
live event trigger system, and a value of 12 indicates a cue created by a
local content replacement system. The splice_event_source and the
splice_event_number together define the splice_event_id parameter that
is inserted into the SCTE 104 message.
splice_event_number
The splice_event_number is the number chosen by the event source to
identify an instance of the cue message. Its value is automatically
calculated by the 7746FSE-GPI-HD+SCTE104 and makes up the lower
28 bits of the splice_event_id.
unique_program_id This parameter is defined as a two-byte parameter and has a possible range of 0 to 65535. According to SCTE 104, the use of this field by
servers and splicers is unknown at this time.

pre_roll_time (ms)
The pre_roll_time parameter is a 16-bit field giving the time to the
insertion point in milliseconds. This parameter has a possible range of 0
to 65535. This field is ignored for splice_insert_type values other than
spliceStart_normal and spliceEnd_normal.
break_duration (tenths)
The break_duration parameter is a 16-bit field giving the duration of the
insertion in tenths of seconds. This parameter has a possible range of 0
to 65535. This field is ignored for splice_insert_type values other than
spliceStart_normal and spliceStart_immediate.
avail_num
This parameter is an 8-bit field giving identification for a specific avail
within the current unique_program_id. The value follows the semantics
specified in SCTE 35 for this field. It may be zero to indicate its non-
usage. This parameter has a possible range of 0 to 255.
avails_expected
This parameter is an 8-bit field giving a count of the expected number of
individual avails within the current viewing event. If zero, it indicates that
avail_num has no meaning. This parameter has a possible range of 0 to
255.
auto_return_flag
If this field is non-zero and a non-zero value of break_duration is
present, then the auto_return field in the resulting SCTE 35 section will
be set to one. This field is ignored for splice_insert_type values other
than spliceStart_normal and spliceStart_immediate. Within this
implementation this field is fixed to 0x00 and cannot be modified.
