Commercial TV lntro
Commercial TV's differ from non-commercial TV's in many areas. One

in particular is external control of the TV from third-party interactive
systems. Today, most commercial applications incorporate a third-party

control system, Master Antenna Television System (MATV), and some
sort of interactivity.

Commercial TV's:

have to be adaptable to the different types of third-party
systems in use today.

have two setup menus, a basic menu and a master menu.
(The master menu allows more control of set operation and

limits access to features commonly found on the basic menu
of non-commercial TV' s.)

have an interface for a third-party controlling device.
incorporate spill-resistant cabinets, (all grills, seams or other

openingsare designed to minimize the likelihood of cleaning
agents or spills entering the instrument and causing

operational problems).
incorporate integral mounting provisions, (mounting bosses

on the bottom of the cabinet that allow affixing the instrument
to existing mounts, brackets, and plates).

have restricted access to channels and menus, front panel
lockout, IR and wired cloning, and de-commercialization

features. (De-commercialization prepares the commercial TV
for after marked resale.)

RCA commercial TV's are indicated by the letter J at the beginning

of the model number and GE commercial TV's are indicated by the
letters GH in the model number. An example ofa RCA commercial

model number is J32430.

Commercial TV Application
Professional / Educational TV's arc mainly used in situations that

require televisions to always perform a particular function such as
always turn on with the volume preset and on the same channel. Certain

features and functions are enabled or disabled depending on the appli-
cation, in this application controlling of the TV externally, although

possible, is not common.

Lodging TV's are similar to Professional / Educational in that some
features are disabled and in some cases none of the TV's controls are

enabled, in a Lodging environment, the TV's are typically controlled by
an external device or set-top box connected to the Digital Serial

Communications lntert:ace (DSCI) jack. When connected to the DSCI
other devices can communicate with the TV sending it commands and

getting front panel or remote commands back from the TV. With this
interactivity, the user can send requests to the controller and do more

than the non-commercial TV. For example: Pay-Per-View and room
service can be requested by the customer using the on screen menu

system. The service can then be billed directly to the room account. This
type of interactivity can even include an itemized list of room charges
and advance checkout for the customer.

usesastandardstereoV4 plug for controlling the TV. The pendant is a

wired remote control used to control basic functions of the TV. There
are two types of pendants; 1) Smart pendant and 2) "Dumb" pendant.

Smart pendants control TV on/off; volume, and channel +/- much like the
standard remote control does. The "dumb" pendant has channel up and
on/off capabilities only. Both smart and dumb pendants can incorporate
volume control of an external speaker and are hardwired to the TV.

Jack Panel
The jack panel is based on a particular application. Although

specific applications require specific jack panel connections, any
of the commercial TV's can be used in a commercial establishment.

The first commercial TV's only had the Pendant connection. As
commercial sets evolved, more interaction between user and the
TV became apparent. The DSCI was added to provide this type of
interactivity. Commercial TV's today have a pendant and or DSCI

port for external control of _he TV.

Note: The DS(T port and Patient Remote Pendant are not used at
the same time, Only one controlling device can be connected to

the TV at a time.

Healthcare Jack Panel
The healthcare jack panel uses the most basic of connections.

There are three connection jacks but only two are used at any given
time. The connections are:

1. Patient Remote Pendant

2. DSCI Port

3. Cable / Antenna

The Patient Remote Pendant uses a standard V4 stereo plug that
allows connection of a wired remote control unit called a pendant

to operate the TV.

The DSCI port uses an eight pin phone jack style plug to connect
the TV to a set-top box for controlling the TV and providing
interactivity.

The Cable / Antenna connection is for the coax cable used to
transmit the TV signal to the TV.

Figures L-3 and L-4 can be found in profcssionaL, educational, orlodging
applications. These applications typically do not use the Patient Remote

Pendant jack. Both jack panels have the DSCL for controlling the TV by
an external system. The other connections are features that are used in
different applications.
The DSCL only jack panel has basic connections and is used in
applications that require DSCL, cable / antenna, and possible video
and audio input. It can also be used with a stereo system.

The connections are:

Video: Composite video input from a VCR, DVD,
camcorder, etc. connected to the TV.

Audio R/L/Mono: Audio signal from a VCR, DVD,
camcorder, etc. connected to the TV to provide audio
input when using composite video.

R/L Out: Audio signal out to a stereo system amplifier

used when higher volumes levels are required.

Cable / Antenna connection is for the coax cable used to
transmit the TV signal to the TV.

connect the TV to a set-top box for controlling the TV and
providing interactivity.

Display Series Jack Panel
The display series jack panel has all the connections of the DSCI

only jack panel with two additional connections, PC input and S-
Video. PC input is for connecting a personal computer to display
computer graphics and text on the TV. S-Video is used when a
higher quality video is needed. When using S-video, the
corresponding audio in needs to be connected.

PC INPUT (Scan Converte O

The function of the built-in Scan Converter is to serve as an
interface between a computer and the television. This allows the

television to be used as a computer monitor. Using the PC INPUT
connector, the TV can accept the computer signal and convert this
signal into a standard NTSC Y/C signal for display on the TV
screen. Computer signals with resolutions up to 2048 X 1536 @

152 hertz vertical refresh are possible.

RemoteControls (Master & Basic)

A Master remote is different from a Basic remote in menu access only.
Master remotes have special coding to access the hidden or master menus

of the TV. Basic remotes can only access the basic menus that are
allowed by setup of the master menu. To setup a commercial TV
functions, the master remote or Clone PRO __jclone box needs to be used.
No other remotes can access the master menus. When using the basic
remote to make changes in the menu, each time the set is turned off. the

changes will return to the detZault settings when powered on. Changes
made by using the master remote will remain when power is removed

from the TV. These settings can only be changed back by using a master
remote or the Clone PRO TM. Aside from the special coding used to

access the master menu, the master remote is the same as the basic
remote.

appear to control the TV via 1R but are doing so through the DSCI input
on the back of the TV. These remotes are typically used where pay-per-
view systems are in place and require a set-top box for control. These
remotes do not have the coding to control the TV directly, but control the
set-top box instead. The set-top box then controls the TV via the DSCI

jack. Therefore, when the TV is not responding to remote commands,

check the set using the Clone PRO _Mclone box connected to the DSCI
port. if the TV responds to the Clone PRO _j, there is nothing wrong with
the TV. (Functions of the Clone PRO _Mmay be limited by the setup of
the TV and type of control the set-top box has. At a nfinimum, power on/
off should work.)

A Thomson universal remote is capable of many other operations that a
basic remote is not, for instance; programmable to other brands of VCR,

Cable/Sat, and audio systems. Like the basic remote, the universal can
access the basic menu but is not capable of getting into the master menu.

Universal remotes have the ability to control two Thomson TV's that are
in the same vicinity but independant of each other. TV 1and TV2 buttons

allow controlling two sets using one remote. See Master Menu section,
on page 15, for TVI and TV2 setup.

NOTE:
There are other remote hand units specific to some set-top boxes that

Basic Menu

The basic menus are accessed using the basic remote or the front

panel Menu button. The menus that are available, depend on the

restrictions set by the master user and the active input. For instance,

if Basic Menu Access has been set to Disabled in the Access and
Power Options menu, the basic menus will not be available.

Many of the changes made in the basic menu will revert to their

master menu settings the next time the TV is turned on. Most all

the basic menu items function the same as their master counter

parts. Refer to the users manual for more detailed operation of the

menu items that are different.

NOTE: Some.features, such as PC Video Input Controls, are not

available unless that input has been selected prior to entering the

menu. This holds true/or both Basic and Master Menus,

Master Menus

By using a Master Remote or the Clone PRO ]Mthe Master "Main Menu"

can be accessed. The master menu sets up how the TV will operate for
the end user. It is important to be extremely familiar with the master

menu and what each feature does. Many times a problem that appears
to be set related is actually improper setup or a misunderstanding of the

menu item's function. Because of the numerous problems that can be
associated with improper menu setup, only the function of each menu

item will be explained.
The following section covers the master menu functions and what

each does. Navigation through the menu is in order of display.

NOTE: Some menu items may not be in all models.

The choices in the Parental Controls menu involve software inside
the TV (dubbed V-Chip), which allows blocking of TV programs

and movies containing violence, sex, or other content not intended
for children. Programs can be unblocked by entering a password.

Note the default state is off and basic users have no access to
Parental Controls. When turned "on,'" the software reads a code

that most broadcasters send with programs. That code tells the
software the program's age-based rating (TV-MA, TV-14, etc.)
and content themes (Violence (V), Adult Language (L), etc.). If
the rating or content themes that the program contains are blocked,
the message "This channel is not approved for viewing" will be
displayed. Broadcasters are not required to provide content themes,
so programs received with no content themes will only be blocked
if their age-based rating is blocked. Movies that have been given a
rating of"Not Rated," and programs that are considered "un-rated
"because no code has been sent by the broadcaster, can be blocked.

External Control of the TV
In most applications the commercial TV is controlled by a third-

party device hard wired to the set. This is accomplished in on...._eof

two ways.

1. Digital Serial Communication lntert:ace (DSCI)

2. Patient Remote Pendant plug (PRP)

The DSCI provides more control of the TV then the Pendant. The DSCI
uses serial communication, IR communication and is capable of two-way
communication. It also provides + 12Vdc power for third-party use. The

PRP is used primarily in Healthcare applications.

Interactive Systems (Set-Top Boxes)

There are several different interactive systems available today.
The most common ones are: On Command Video and Lodgenet.
Most use a set-top box to provide interaetivity. When connected to
the DSCI, the set-top box can provide pay-per-view movies, media-
retrieval and control, patient and staff education, guest services,
and other automated control of the TV. The fundamental equipment
required for an interactive system includes; in-room hardware (set-
top box), head-end (MATV), and communication system. The set-
top box is hardwired to the TV's DSCI jack. See MCR Module

Connections on page 27 for a pin out of the DSCI.

Patient Remote Pendant (PRP)

There are two types of wired Patient Remote Pendants, "dumb" and
"smart". A "dumb" pendant is nothing more than a switch closure

between two contacts. On healthcare TV's this contact closure
tells the set to channel up once for each key press, in the event the

set is powered off; the first key press will turn on the set and each
preceding key press changes the channel. Once the last channel has
been reached, the next key press will turn off the set. There is no
other interaction between user and TV with a dumb pendant.

Using a smart pendant provides the user with more control of basic
functions like volume up and down, channel up and down, and on/
off2 The smart pendant uses data pulses similar to a remote control.
Both smart and dumb use a standard stereo V4" plug to connect to
the TV for communication and can have audio out to a pendant
speaker. Some pendants have mechanical volume controls to adjust
audio level of the pendant speaker. See MCR Module Connections
on page 28 for a pin out of the PRP.

MCR Module Connections

The commercial TV uses an MCR (remote-control module) for third-
party connection and control. The MCR module has one and/or two

control jacks on it.

1. Digital Serial Communication lnterIZace (DSCI)

2. Patient Remote Pendant plug (PRP)

The type of commercial installation determines what MCR module
or connections are available. All MCR modules have the DSCI,
but only the healthcare has a PRP. The DSCI has serial
communication, infrared (IR) remote output, and is capable of two-
way data transfer for complete monitoring and control of the
television. It also provides +12Vdc power for third-party devices.
The PRP, used with Healthcare applications, has limited
interactivity.

Clone PRO TM (CBX-203)

The Clone PRO ]M clone box is a self contained, baltery operated,

microprocessor controlled device used to facilitate the programming
process for commercial TV. Because the commercial TV has a

wide range of features and options, programming of multiple sets
can be time consuming. In most commercial applications there

maybe several to hundreds of sets that all need to be setup the same
way; this is where the Clone PRO _j helps. With a learn / teach

feature, the Clone PRO _Mcan program several sets in less time than
someone going into each sets menu and setting them up manually.

By programming one set and using the Clone PRO _Mto learn the
TV's setup, the other televisions in the establishment can then be

programmed using the teach function of the Clone PRO _j.

Additionally, the Clone PRO _Mcan be utilized as a tool to:

1. Clear the television's memory.

2. Prevent unauthorized and unsupervised programming.

3. Allow or disallow front panel programming.

4. Commercialize or de-commercialize a set.

5. Set legacy bit. (For OnCommand operation)

6. Troubleshoot the MCR board communication.

There are two ways the Clone PRO _Mcan accomplish programming
a set. 1) Digital Serial Communications Interface (DSCI)
"SmartPlug", and 2) Wireless remote operation. When using DSCI
("SmartPlug"), the Clone PRO _Mis physically connected to the TV
via a standard (1 to 1, non-flipped) 8-conductor computer-network
cable. When using IR the Clone PRO _Mneeds to be pointed (line

of sight) at lhe IR receiver of the TV.

Troubleshooting Hints and Tips

As with any troubleshooting a logical thought process is required to
accomplish the task. The first thing when dealing with commercial TV
is to check setup menu for proper setup. A short cut metbod to determine
if the set has a setup problem is to take a working TV set and learn using
tbe Clone PRO _M.Then using the Clone PRO TM, teach the set in question.
This procedure will insure the two sets are setup the same.

The Clone PRO ]Mis a useful tool in troubleshooting the commercial TV.
With a complete understanding of how the Clone PRO TM works, one can
determine if the TV or the system it is hooked to is the problem. Using
the DSCI communication port as the test point, hook up the Clone PRO ]M
using tbe cable supplied and check for proper communication by either
teaching or learning tbe set. The green busy and ready LED's indicate
data communication. Turning on the set and channel change are another
indication that the DSCI is working.

Patient Remote Pendant can be tested by taking a known working
pendant and connecting it directly to the back of the TV. if the set works,
check the wiring from the pendant to the TV. The PRP is a simple three-
wire connection but if wired wrong it will not work.

TV will not turn on

Check to make sure it is plugged in.

Check the wall receptacle (or extension cord) to make sure

it is "live " by plugging in something else.

Check batteries in remote control.

Insure remote control is aimed at the remote sensor on the
TV.

TV power or remote configurations may be preventing
this. Use a master remote control to change menu settings.

TV turns on or off unexpectedly

The Scheduled Off or Scheduled On function may have
been activated in the Time and Timers menu.

The Sleep Timer or Energy Saver function may have turned
the TV off. Check menu setting under Sleep Timer and
Energy Saver. Note: Sleep timer can be re-set by
unplugging the TV, wait 5 minutes and plug it back in.

Analog

A system in which signals vary continuously in contrast to a
digital system in which signals vary in discrete steps.

Anti-aliasing

The process of reducing the aliasing effect. Usually involves
placing a gradual gradient from the slanted line color to the
background color to "smooth" the jaggies.

Aspect Ratio

The ratio of television screen width to height. The standard
aspect ratio is 4 to 3. in computer jargon, television screen size

is 768 x 576 pixels including overscan, although actual viewing
screen resolution is normally considered to be 720 x 484. High

Definition broadcasts will normally be closer to a 16 X 9 format.

ATSC

Audio

The sound portion of the television signal.

A/V Cables

Audio/Video Cables carry the baseband audio and video output
signals demodulated from the RF channel received by the tuner.

Baseband Video

The composite NTSC standard signal that contains all the color
and black/white information needed to produce normal video on
a television screen. The baseband signal originates at the
production Facility or studio and later modulated, or mixed, onto
a channel carrier for transmission over broadcast, cable, MATV
or SMATV systems. The receiver or television must then strip
off the channel carrier, leaving the original composite signal.

CAV (Component Analog Video)

the quality is approximately equivalent to that of analog NTSC.
This equivalent quality may be achieved from pictures sourced
at the 4:2:2 level oflTU-R Recommendation 601 and subjected
to processing as part of the bit rate compression. The results
should be such that when judged across a representative sample
of program material, subjective equivalence with NTSC is

Luma and Chroma difference components normally recognized
as a PAL video signal standard where Y=Luminance, U=Red-Y,
V=Blue-Y. These signals can be recombined to form RGB
video. Generally cleaner than other methods requiring some
frequency conversion of the separate color and luminance signals.

Y, CI, C2

A general set of CAV signals. Y is the luma signal, C 1is the first
color difference signal and C2 is the second.

Y, Cb, Cr

Digital expression of the color difference signals. Cr is the
digital interpretation of R-Y, while Cb is the digital interpretation

of B-Y.

Y, Pb, Pr

Analog expression of the color difference signals. Pr is the
equivalent to R-Y, while Pb is equivalent to B-Y.

Y, R-Y, B-Y

The general set of CAV signals used for some encoder/decoder
systems in PAL and NTSC systems. Specifically, Y is luminance,
R-Y is the first color difference signal and B-Y is the second.
Y,Pb,Pr is a version of this system. (See also RS-170)
