1. DESCRIPTION
1.1. The HOP3147C02
HOP3147C02 module is a VBI information processor for 3G/HD/SD-SDI digital video
signals with multiple functions as described below:
Transmission of closing contact information within the 3G/HD/SD-SDI video signal. The
HOP3147C02 can be used both to read the status of its eight GPI inputs and encode it
into a video signal or to decode the information inserted by another HOP3147C02 and
present it in the eight GPO outputs.
Status information can be transmitted by means of teletext packets or using one
channel of embedded audio.
In the first case, the GPI's state information is coded as data within a reserved teletext
packet which is transmitted once per frame. The transmission method depends on the
video format module is using. When working with SD-SDI signals, the teletext packet
modulates the amplitude of the luminance of the active portion of a vertical interval line
according to standard ETSI ETS 300 706. When working with 3G/HD-SDI signals, teletext
packets are transmitted within an ancillary data packet as defined in the "Free TV
Australia Operational Practice OP-47".
In the second case, the GPI's state information is encoded in one embedded audio
channel by means of several tones with security information to avoid bad decoding.
Activation or deactivation of the GPOs is done frame by frame according to the
information received. If teletext packets are no longer received, the incoming encoded
audio is invalid or the video signal fails, two different behaviors can be chosen: freezing
of the GPO's status or opening GPOs 1 to 7 and signaling the failure by closing GPO8. If
conflicting GPO status information is received in the same frame, the latest information
is always used.
Teletext bridge. Allows insertion of teletext received from the IN-B input into the video
signal received from the IN-A input, regardless of the format of the input signals.
Teletext line mapping is controlled by means of a table that allows enabling or disabling
of the insertion of each line, as well as the reassignment of the lines.
Received teletext OSD insertion. Displays teletext/subtitling pages contained in the
video signal delivered by the module.
VITC-ATC bridge. Allows insertion of the the time code information received from the
input IN-B into the video signal received from the IN-A input, regardless of the format of
the input signals. When the received input signal is HD or 3G the time code is read from
ATC packets while in SD it is read from VITC.

Albalá Ingenieros | Manual HOP3147C02
Format identification information inserter. Allows insertion of aspect ratio information
into the video signal in VII (SMPTE RP 186), WSS (ITU-R BT.1119-2/EIAJ CPX-1204) and
AFD (SMPTE 2016-3) formats.
Fully user configurable insertion of ancillary packets. The HOP3147C02 module has
FLASH memory to store a 2048 bytes file containing up to eight 256 bytes packets for
this purpose.
Insertion and readback of automation information as per SMPTE ST 2010 and SCTE 104.
The HOP3147C02 can insert ancillary data packets with information for
user-configurable automation that can be activated using the GPIs. The unit also
provides a reader capable of decoding the information present in these packets for
analysis or to perform operations via the GPOs.
Cue Tone insertion (beginning with version 1.6). The HOP3147C02 can insert user
configurable Cue Tone sequences that can be activated by remote control or via the GPIs.
It is possible to monitor the HOP3147C02 status remotely using a communications
controller module installed in the same mounting frame. In addition, certain controller
modules provide SNMP management and the ability to record events in a file including
date and time information for further analysis.
The HOP3147C02 is a TL3000 terminal line module and can be housed in a three rack
unit (3 RU) UR3000 mounting frame or a 1 RU UR3100 mounting frame.

3. INSTALLATION
THE HOP3147C02 MODULE CONTAINS ELECTRONIC DEVICES SENSITIVE TO
ELECTROSTATIC DISCHARGE. Always use antistatic bags clearly identified
with a high degree of shielding for storage and transportation.
The HOP3147C02 module is composed of two parts: one HDE3000P14 main board and
one HDE3000P15 rear board. Both parts must be installed in a UR3000 or UR3100
mounting frame following the instructions in the corresponding section of this chapter.
3.1. Initial inspection
Verify that the package has been properly handled during transport. After opening the
packaging, check that one HDE3000P14 main board and one HDE3000P15 rear board are
inside.
You must notify your Albalá Ingenieros distributor or dealer of any damage or defects
observed.
Follow the instructions in this manual to install this module in the mounting frame.
3.2. Safety instructions
•This equipment must be connected to a mains outlet with a protective
earth connection. Never use extension cords that do not have protective
earthing connection. The lack of an effective electrical connection between
the ground pin in the mains input connector of the equipment and the
protective earth of the electrical power distribution can cause serious harm.
•All modules of the Albalá Ingenieros TL3000 terminal line can be
hot-plugged or unplugged without suffering any damage or affecting the
processes that are currently taking place in other modules in the same
mounting frame. When a module is installed in an empty bay of a mounting
frame, it is necessary to mount the rear board that is part of that module.
Prior to installing this board, the mounting frame must be disconnected
from the power supply network. This is required because in addition to the
risk of electrocution for the person handling the device it is possible that a
high instantaneous current coming from the power supply could damage
the connectors and components of the mounting frame and/or the rear
board.
11

Albalá Ingenieros | Manual HOP3147C02
•The HOP3147C02 module and the mounting frame should always be
installed, maintained, operated and removed by personnel with sufficient
technical qualifications. The equipment should never be placed in damp
areas, near splashing liquid, or in explosive or corrosive atmospheres.
Neither modules nor mounting frames can be used in applications that
could endanger human life.
3.3. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.4. Power considerations
The UR3000 and UR3100 mounting frames can house as many HOP3147C02 modules as
will fit in them.
3.5. Installing the module in the mounting frame
The steps needed to install the HOP3147C02 module with the rear board in the
mounting frame are:
1 - Disconnect all power cords from the power supplies of the mounting frame.
2 - Remove the blank panels covering the front and rear of the empty bays chosen for
installing the HOP3147C02 in the mounting frame.
3 - Install the HDE3000P15 rear board ensuring that its 12-pin connectors are properly
aligned with the mounting frame´s mating connectors. Check that the orientation of
the board is correct by looking at the placement of the text printed on it according to
the illustration below.
4 - Attach the rear board to the mounting frame with two M3 metric screws and tighten.
5 - Insert the HDE3000P14 board (main board of the HOP3147C02 module) into the front
of the mounting frame. The edges of the card slide into two plastic guides inside the
mounting frame.
6 - Affix the main board to the mounting frame using the two screws included on the
front panel.
After these steps, the module is ready to be connected to other equipment.

3.6. Interconnection
The following figure shows the HOP3147C02 module rear board connector layout.
Rear view of the HOP3147C02
The HOP3147C02 module has two 3G/HD/SD-SDI digital video inputs (IN-A,IN-B), four
3G/HD/SD-SDI digital video outputs (OUT1-A (LOOP),OUT2-A,OUT1-B,OUT2-B), eight
GPI inputs and eight GPO outputs.
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
3.6.1. Electrical SDI video connections
The IN-A input acts as a main input, while the IN-B input acts as an auxiliary input and
is used only for teletext bridge and/or VITC/ATC bridge functions. All output signals
come from the video signal IN-A and it is possible to choose independently if decoded
teletext OSD is inserted into the section A and section B outputs.
14

Albalá Ingenieros | Manual HOP3147C02
All electrical SDI video connections are BNC type. The following suggestions should be
kept in mind when wiring the electrical signals.
BNC connectors used on cables must be suitable for the high frequencies of digital
video signals: it is strongly recommended to use high quality connectors from well
known manufacturers.
All coaxial cable used must be Belden 1694A or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the HOP3147C02. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
The use of analog video coaxial cables RG-59 type or similar is not recommended for
digital video except for very short distances.
3.6.2. GPI connections
The GPI inputs use 3.81mm pitch terminal block connectors and their equivalent
circuit is as follows:
Before connecting these signals please consult the maximum values shown in the
specifications section. Never connect dangerous potentials to GPI inputs.
15

Albalá Ingenieros | Manual HOP3147C02
3.6.3. GPO connections

4.2. Functional description
4.2.1. Teletext insertion mode
The HOP3147C02 can transmit coded information from eight closed contacts (GPI1-8)
with packets of reserved teletext with two different content types. When the format
of the incoming video signal is SD the HOP3147C02 inserts packets of reserved
teletext in one or two vertical blanking interval lines of field 1 of the video signal as
per ETSI ETS 300 706. When the format of the incoming video signal is HD or 3G an
ancillary data packet is inserted into the vertical blanking interval of field 1 as per the
recommendation of OP47 of the "Free TV Australia" consortium with the same
content as is transmitted in SD. Of the two types of ancillary data packet described in
in OP47 the one used is "SUBTITLING DISTRIBUTION PACKET (SDP)".
The HOP3147C02 module is able to insert GPIs information using two different
teletext packets/formats which are the following:
• The content of teletext packet 1 is as follows:
0xAA, 0xAA, 0xE4, 0x0B, 0x57, GPI1,GPI2, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

GPI1 is GPIs 1 to 4 with Hamming encoding 8/4 and GPI2 is GPIs 5 to 8 with Hamming
encoding 8/4.
The following table must be applied to the 8/4 Hamming encoding:
0xA8, 0x0B, 0x26, 0x85, 0x92, 0x31, 0x1C, 0xBF,
0x40, 0xE3, 0xCE, 0x6D, 0x7A, 0xD9, 0xF4, 0x57
• The content of teletext packet 2 is as follows:
0xAA, 0xAA, 0xE4, 0xD9, 0x57, 0xA8, 0x92, 0x6D,

8/4 encoding.
19

Albalá Ingenieros | Manual HOP3147C02
The following table must be applied to the 8/4 Hamming encoding (similar to the
previous table but with bits reversed, ex. 0001 -> 1000):
0xA8, 0x40, 0x92, 0x7A, 0x26, 0xCE, 0x1C, 0xF4,
0x0B, 0xE3, 0x31, 0xD9, 0x85, 0x6D, 0xBF, 0x57

0x1F, 0x94, 0x59, 0x21, 0x4E, 0x9D, 0x08, 0x28
where first two bytes are CRC1 and CRC2 when the GPIs have a value of 000000, the
following two are CRC1 and CRC2 when the GPIs have a value of 000001, etc.
When this teletext format is used a maximum of six bits can be transmitted. The two
most significant bits are always set to 0.
The following parameters are configurable via control software:
-Teletext packets to be transmitted: none, the content of packet 1, the content of
packet 2 or both.
-The numbers of the lines of the vertical blanking interval of field 1 of the SD
television signal in which each teletext packet is to be inserted. If the same line
numbers are selected for both, only the content of packet 2 will be inserted.
-When the signal received by the module is HD/3G the OP47 packet is only
transmitted if one of the teletext packets has been selected for transmission.
-The number of the line of the vertical blanking interval of field 1 of the HD/3G
television signal in which the OP47 ancillary data packet is to be inserted (Only for
HD/3G).
Note that the line where the OP47 packet is to be inserted is not related to the lines
where the teletext packets are inserted in SD. The first line number references the
ancillary data packet position in the HD signal while the second line numbers
reference those lines in which the teletext packets are inserted in the SD signal.
