Description
HD200
The HD200 is a compact unit that converts any high
definition input to the standard definition equivalent..
It is an ideal camera downconverter, converting a HD
camera into a spatially over-sampled device.
The HD200 offers SDI component digital output with
EDH as standard, and analog component and
composite outputs. Aspect ratio conversion is integral
with pan, tilt and zoom controls allowing the key part
of the HD image to be available at the output. An HD
serial digital component input is available as an
option.
With a three dimensional filter structure, HD200 can
handle interlacing without loss of quality so that those
fine lines in the input are truly resolved. In addition to
automatically sensing the input standard, HD200
allows features such as up to 4 x zoom with pan and
tilt so that the wanted area of the picture can be
enlarged to fill the television screen.

HD200 SECTION 1
HD200200599 Version 1 Issue 5 1.3
Overview
The HD200 from Snell & Wilcox is able to convert a
wide range of high definition formats into standard
TV video without artificial degradation.
The HD200 performs true format conversion. It
does not restrict the operation of the HD source so
that the HD monitor can continue to operate at full
resolution. It uses high quality wide aperture
three-dimension interpolation to perform true scan
format conversion.
Vital to any high quality conversion system is its
ability to handle motion in the graphics. Animated
graphic sequences are nowadays the norm and so
it is no longer possible to use a simple converter
that just drops fields to reduce the field rate to 50 or
60Hz. Converters that use this technique will
introduce unacceptable motion judder. As we
move into the era of virtual studios the motion
portrayal issue becomes even more important.
Even though the input format is high definition the
use of three-dimensional interpolation is necessary
if the resulting output is to be accurately interlaced.
Without this, motion portrayal would suffer. The full
resolution is sampled and stored inside HD200 and
is used to build the necessary output pixels.
The output, by definition, needs to use interlaced
scan as it is a standard TV video signal. Through
the use of Snell & Wilcox’s patented three
dimensional interpolation techniques, the twitter
often associated with interlaced scan is
dramatically reduced leading to stable TV video
that is pleasing to watch.
The correct shaping of the three dimensional filters
is the secret of the HD200’s ability to correctly
anti-alias the video without introducing the softness
often associated with over filtered pictures. This
filter shaping experience has been built up over
years of producing top of the range PAL-NTSC
standards converters.
A range of outputs is available including Serial D1,
YPbPr, Y/C, and analog composite. The
component input is accurately matrixed to fully
compliant broadcast quality YPbPr. Many
adjustments such as black level are adjusted
automatically, but there are also manual controls
available to allow the optional adjustments of some
proc-amp parameters.
A useful feature is the HD200’s ability to zoom in or
shrink the size of video from the HD source and
offset it both vertically and horizontally.

Adjustments for Analog Input Only
Luma Gain
The l
uma gain may be adjusted over a range of
±3 dB in steps of 0.1 dB
Chroma Gain
The chroma gain may be adjusted over a range of
±3 dB in steps of 0.1 dB.
Black Level
The black level of the output signal may be
adjusted over a range of ±50 mV in steps of
0.1 mV.
Y/C Delay
The relative horizontal timing between the
luminance signal and the chrominance signal may
be adjusted with these controls.
The Delay Horiz will change the horizontal timing
(left/right) by up to +16 to –8 pixels in steps of
1 pixel. A positive value of delay will shift the
chrominance signal to the left of the picture and a
negative value will shift the chrominance to the
right of the picture.
The luminance signal will remain stationary.
mENHANCE
This function allows horizontal/vertical
filtering/ehancement and Gamma correction to be
applied to the picture.
+4 to –3 levels of horizontal filtering, and +1 to –2
levels of vertical filtering may be applied, in steps of
single levels.
+5 to –4 levels of Gamma correction may be
applied to the signal.
Not that these are arbitrary levels; they are not
actual values of Gamma.
Gamma Notes
In this context Gamma is defined as the shape of
the transfer characteristic between input signal
amplitude and output signal amplitude. Normally
the shape is a straight line with a slope of unity and
the output level follows the input level over the
dynamic range of the signal. i.e. Gain does not
change with signal level.
If the shape of the transfer characteristic is
changed to a curve, gain will then change with
signal level and can be arranged to either stretch
black parts of the signal and compress white par ts
or stretch white parts and compress black par ts of
the signal.
Generally the output level is related to the input
level by the equation
Vout = Vin
γ
Where γ = Gamma Value
The Gamma correction is only applied to the Y
(Luminance) signal. An example of the effects of
gamma correction is shown below.
This function is particularly useful for cor recting the
non-standard Gamma characteristics of some
computer-generated images.

Remote Control
ROLLCALL™ OVERVIEW
The Snell & Wilcox RollCall™ remote control protocol fitted to HD200 provides full remote control of all
functions, and in addit ion, integration with a range of compatible units all of which can be controlled f rom a
variety of graphic al c ontrols.
Although offering a unified set of protocols, the RollCall™ system supports three physical connection
arrangements.
RollCall™ communication may be via either a 9 pin `D' connector configured to RS485 or via a 75-Ohm
coaxial cable connection to the network allowing long distance multi-drop coaxial inter-connections. The
address of a unit is s et by two Hex s witches, eac h unit having a diff erent address . In addition an RS 422 port
allows single point-to-point communication wit h a s im plified set of Prot oc ols.
The system may support multiple slave operation, multiple control operation or as a single network with a
choice of coaxial or RS485 int erf ace connect ion. High dat a rat es of 2. 5Mbit s/s ec are used on the coaxial port
and RS485 port, and up to 38.4 kbits/sec on RS 422 port.
Further RollCall™ developm ents support Et her net and Internet c ontrol, so providing the ultimate in ‘Remote
Control’

Control of HD200 with other RollCall Units
Other RollCall units, fitted with a K UDOS IQ act iv e front panel, may be us ed to control the HD200.
The KUDOS IQ active f ront panel has similar operation to t he HD200 front panel, the main differences being
the functions of the dedicated push but tons.
KUDOS IQ A c tive Front Panel
When using the KUDOS IQ active front panel to control the HD200 unit, the display windows and their
associated push buttons, will function in the same way as those on a HD200 front panel; however, the
dedicated push buttons will operate functions as described in Section 1 of the K UDOS IQ Modular Syst em,
Operator’s Manual, 1U Ac tive Control Panel, Dedic ated Push Buttons.
To access the Output, Size, Filter, Freeze, Pattern, Save, Input, Video, Config, Mono, Glk and Recall
functions (dedicated buttons on the HD200 front panel, but buttons not available on the KUDOS IQ active
front panel) connect to the HD200 unit using the Modules function (see KUDOS IQ Modular System,

HD200 remote control
The HD200 unit uses RollCall™ that is a software protocol based around an RS422 interface. This document
describes how to use RollCall™ to interface with a HD200 computer graphics down converter.
The wiring for the cable connection from HD200 to the RS422 on a PC is drawn on page 16.
The protocol is a binary packet stream between controller and HD200. Comma separators are shown in this
document for clarity, but should not be included in the actual protocol. Unless otherwise indicated all numbers
in this document are hexadecimal representations of 8 bit (1 BYTE) binary numbers.
Before controlling a unit, it is necessary to form a session with that unit, by way of a
CONNECT
command.
Then control of the unit is performed by use of the
SET PARAMETER command with associated data
being unit specific.
It is also possible to look at the settings of the HD200 using the G
ET FUNCTION STATUS command, the
reply being a
RETURN FUNCTION STATUS message.
Finally once the controller no longer wishes to control the unit it can close the session with a
DISCONNECT command.
These 4 commands are Rollcall™ commands, and as such should not be confused with the HD200 specific
commands which are carried in the data block of the
SET PARAM command.
Reserved characters
The software protocol used is a packet-based system which uses a start and end control byte to define the
start and end of each packet.
CMD Definition
0x02 Start of packet (STX)
0x03 End of packet (ETX)
0x1B Escape character (ESC) for STX, ETX and ESC
An escape sequence is used if the start end or escape control code values are required in the packet.
The escape character is inserted, and the desired character has its MSB inverted.
The table below shows the 2-byte replacements.
Note that the value of the Data Length part of the packet will remain the same, since this escape character
sequence is handled at a lower level.

HD200 SECTION 6
HD200171198 Version 1 Issue 4 6.3
Sending commands
The Rollcall protocol defines the format of all messages sent to the HD200. It consists of 4 distinct parts:
i) The packet header consisting of the start byte, destination address, source stream and destination
stream. This is constant with the exception of the HD200’s physical address.
ii) The Rollcall command, block consisting of a data length that includes the rollcall command, the
command required, (1 byte) and the command flag (1 byte). This document details four
ROLLCALL commands.
iii) The data block. This varies dependant on which ROLLCALL command is sent, and is HD200
specific. Use the tables at the end to fill in this section.
iv) The packet tail consisting of a checksum (use 00 to ignore) and the stop byte.
The protocol is presented below.
In this document the packet header is shaded. Only changed if hardware is altered.
The remote command is lightly shaded. Data length for command + data
CONNECT / TERMINATE / SET PARAM
/ GET FUNCTION STATUS
are the four cases used in this note.
Data is left unshaded. Every Command is different.
Packet tail is shaded. Only changed if hardware is altered.
The only difference between commands is the command number, the length of data field and the data which is
sent with the command. i.e. the packet header is the same.
Establishing a session
CONNECT
Before commands can be sent to the HD200 unit, a session needs to be set up. The way in that this is done, is
to send a data packet with the
CONNECT command. Here is the byte sequence.
Nominal Value Description.
0x02 (Start Packet (STX))
0x00, 0x00, 0x26, 0x00 (Hardware specific, HD200 net address) **
0x00, 0xFF (HD200 stream index = Unknown)
0x00, 0x00 (Controller stream index)

**NOTE: The value of the thir d byte in the hardware specific net address should be the value set on the
hex switch that is located on the front of the main board of the HD200. If you change this switch,
substitute new value in all packets. As shipped the value is 26

The
Data length
field for GET FUNCTION STATUS is 2 bytes.
In this case the
command number
is a word (two-byte) length field which contains the number of the menu that
we want to know the status of.
The parameter or mode are not included in the G
ET FUNCTION STATUS packet since it is these which we want to
know!
Included below are a few examples of G

RETURN FUNCTION STATUS
After a G
ET FUNCTION STATUS command has been sent a RETURN FUNCTION STATUS packet should be
expected back from the HD200 unit, instead of an Acknowledge packet. It is in a similar format to the
commands:
0x02 (Start Packet (STX))
0x00, 0x00, 0x26, 0x00 (Hardware specific, HD200 net address)
0x00, 0x00 (HD200 stream index)

0x00 (RollCallTM command flag)
Data items (8 bytes, HD200 specific as per tables.)
0xXX, (Checksum)
0x03 (End packet (ETX))
The
Data length
field for RETURN FUNCTION STATUS is 8 bytes, and consists of the following:.
The
command number
is included and is a word (2 byte), and should match the command number sent in the
GET FUNCTION STATUS command.
The
mode
is included and is a word (2 byte), and should be 00 01 for VALUE.
The
Parameter
is a long (4 byte) field, which gives the current value of the paramter associated with the
command.

HD200171198 Version 1 Issue 4 6.11
Tables to show the commands of the HD200
The
Scale and unit
field signifies the amount that the parameter sent with a command is multiplied by. For
example when the Luma Gain is being set a value between -30 and +30 is sent which is then multiplied by 0.1
to give an actual value of -3 to +3 which has the unit dB. The numbers are decimal in this column.
The Step unit indicates the amount by which parameters sent with a command can be stepped by. For
example the Horizontal picture size command has a range of acceptable values between 170 and 560 and
should be stepped in units of 10. This means that values like 175 and 195 are not acceptable. This numbers
in this column are decimal.
Note: commands without a parameter field expects a number to be sent to set the actual value of the
parameter. For example the Luma gain command which expects the required value of the Luma gain to be
sent to the unit. The format of the numbers to be sent is 2’s complement 4 byte to allow negative numbers to
be sent. For commands where the range goes from negative to positive, the negative numbers can be
expressed by using binary twos complement. If the default setting for a command such as Luma gain is
required the value to send is Max Value + 1.
