Overview
Introduction
Performer-HD has the full functionally of the Performer-SD with the added
ability to switch HDTV video signals.
Full bandwidth HDTV video signals are routed through a 10x1 video ma-
trix. The 10 Inputs and 1 Output will switch uncompressed serial digital
SMPTE 292M at 1.485 Gbps rate and in bypass (non-reclocking) mode will
handle data rates from 10 Mbps to 700 Mbps.
Audio signals are routed through two audio matrices of stereo AES/EBU
channels of 10x1 serial digital audio switching.

High Definition Background
HDTV is a form of digital television, which for home delivery uses MPEG-2
compressed video and Dolby AC-3 compressed audio. HDTV contains at
least twice the resolution of existing analog broadcast television (NTSC,
PAL, and related formats) in both the horizontal and vertical directions
(400% total increased resolution). HDTV is also presented at a 16:9 aspect
ratio, compared to existing analog broadcast’s 4:3 ratio, providing 33%
more picture area.
Related to HDTV is HD serial digital video. For full resolution broadcast,
HD serial digital video is fed to an encoder at the broadcast station which
compresses the video, combines it with compressed audio, and passes the
resultant digital signal to the transmitter for public consumption.

Section 1 — Overview
The biggest technical difference between standard definition (SD) serial
digital video and HD serial digital video is the data rate. HD video has a
data rate 5.5 times (1.485 GBits/sec) that of SD video. HD video intercon-
nections use 75 ohm coax, like SD video, but the correct cables must be used
and cable runs will be limited. Connectors and patch panels must be spe-
cially constructed for HD rates to minimize signal degradation.
Several different HD video resolution and frame rates exist. Probably the
most widely supported formats are 1920x1080 interlaced at 30 frames per
second (1080i) , and 1280x720 progressive (720p) at 60 frames per second.
System Level Architecture
System Level Architecture addresses the configuration of your system and
how the signal flows.
The Performer-HD router is a three matrix frame. The video matrix switch-
es 10 Inputs to a single dual Output. The two audio matrices each switch 10
Inputs to a single 2 channel stereo Output.
The unit is a captive frame that does not require additional cooling.

Vertical Interval Strobe Selection
Performer generates its own Vertical Interval strobe, which times the
switching of video so that switching occurs within a region of each video
field when there is no active video. Performer-HD generates this from look-
ing at the parallel video data, extracting vertical interval timing informa-
tion and sending out a pulse at a specific time during vertical interval. The
DIP switch S4 is used to tell the Performer-HD which line to switch on. The
choices are lines 1, 5, 6, 7, 8, and 9; corresponding to lines 563, 567, 568, 569,
570, and 571 in the second field.
To change the vertical interval strobe setting:
1.

Switcher Polling Address
Serial Communications Protocol Selection
Performer will accept a polling address from 0 to 255. A polling address is
necessary if more than one switcher is being controlled by a single controller. The full address range is not available to all protocols. Refer to the list
below for protocol address ranges:
■ Performer ASCII Full Range
■ GVG Model 100 or 110 Full Range
■ SMPTE 3245-E 40-255 (28H-FFH)
Performer is designed to allow serial control from multiple sources. Several
communications protocols are serviced; RS232, ASCII and SMPTE are
available by setting the proper switches. Protocols and their applications
are listed in Table 2-4.
To set up a protocol, select protocol, message parity, bit rate, and switcher
polling address. For ASCII protocols, also set serial port data bits at 7 or 8.
For other protocols, the data bits are automatically set at 8. Performer serial
port stop bits are automatically set at 1.

Operation and Maintenance
Introduction
The Performer-HD will select any one of the ten input sources for output
on its single destination. Protects can be set so that the current selection is
locked and prevented from accidental change.
It is possible to control a Performer-HD from a 110 Production Switcher, or
from an RS232 or RS422-compatible terminal or computer. Control from a
Production Switcher is invisible to the Production Switcher operator (providing the Production Switcher is appropriately equipped and configured).
Use of RS232 or RS422 control via a terminal or computer is dependent
upon configuration and connection requirements. The Serial Protocol Descriptions provide the technical information needed for control from production switchers and terminals.
Performer-HD Front & Remote Panel Operation
When using a Performer-HD with any remote controller, the PerformerHD is the master panel; it can remove protects placed by the remote controller. Except for this difference, the following operating descriptions apply to both the local integrated control panel and the remote control panel.
The Performer-HD panel display does not tally Source, destination, and
level offsets. When several panels used on a bus are used to control several
Performers, other means (such as labeling) must be used to identify the
Performer associated with each panel.

Joystick Override Operation
Joystick override control is used primarily when several camera operators
are using a common monitor to check the adjustment of their cameras. Each
camera control unit (CCU) has a momentary contact switch which is wired
to the
OPTION connector of Performer-HD. (See the Installation section of this
manual.) The Performer-HD output is connected to a common video monitor. Joystick override operations follows.
An initial source is sent to the monitor using the Performer-HD control
panel. This will be the default source.
To use the Joystick Override:
1. Press and hold the switch on the CCU to check the signal coming out of
the camera. As long as the switch is held down, the video of the
associated camera is displayed on the monitor.

Performer-HD ASCII Protocol
Performer-HD ASCII allows control of the Performer-HD from a host terminal or computer using standard ASCII characters. Multiple Performers,
each assigned a unique address, may be controlled over a common RS422
bus. All characters are 7-bit ASCII (the eighth data bit out of the PerformerHD port is ignored). A ninth data bit may be used for parity if desired.
Command Line
A command line consists of series of bytes in the following format:
<CR><Adr Hi><Adr Lo><Len Hi><Len Lo><Data>
All bytes are hex ASCII (characters 0-9 [30H-39H] and A-F [41H-46H]), except for <CR>. A hex ASCII character specifies 4 bits or 1 nibble of information and is used in high/low pairs to specify a complete byte of
information. Received ASCII nulls (00H), spaces (20H), and line feeds
(0AH) are ignored and are not included in the byte count.
Command bytes have the following values:
Table 3-2. Command Bytes Values
Command Description
<CR> REQUIRED carriage return character (0DH)
<Adr Hi> 0-F, high nibble of Performer-HD switch 1 address
<Adr Lo> 0-F, low nibble of Performer-HD switch 1 address
<Len Hi> 0-F, high nibble of byte count for <Data>
<Len Lo> 0-F, low nibble of byte count. Count must not exceed 251 (FBH).
<Data>
0-9, A-Z. Zero or more command strings (see Command Strings).
Number of <Data> characters is <Len>
If the <Adr Hi> <Adr Lo> value is different from the value set at Performer-HD switch S1, the command and all subsequent characters are ignored by the Performer-HD until a new message is initiated using a
carriage return. The carriage return purges previously received data, and
must start each command line.
If a carriage return is received before a command string is complete, the
Performer-HD will display
play.
ERR P will also be displayed on receipt of parity/overrun, checksum,
ERR P for about half a second in the status dis-
or syntax errors.

Command Strings
Commands, <Data>, must consist of exactly <Len Hi> <Len Lo> characters forming a string of zero or more commands. Each command must
consist of a single <CMD> character identifying the command, followed by
any <Data> required by that command.
The following command characters and data are supported.
Table 3-3. Command Characters
<Cmd> <Data> Description
D (44H) <Sources> Data preset, source to destination
A (41H) (None) All-destination Take of current preset matrix
T (74H) <Dest> Take of specified destination only
P (50H) <Dest> Protect specified destination (must be refreshed every 30 seconds)
C(43H) <Dest> Clear protect on specified destination
Serial Protocol Descriptions
R (52H) (None) Reset Performer-HD to factory defaults
Q (71H) <Dest> Query for status of specified destination
S (53H) <Status> Status response
Except for the S command, all of the above are sent by the controller to the
Performer-HD. The S command is sent by Performer-HD to the controller
in response to a Q (Query for status) command. Performer-HD generates a
response to the Q command only.
The R command (Reset) causes Performer-HD to initialize just as if power
had been turned off, then on. No data should follow the R command.
The D command allows matrix crosspoints to be preset but not actually activated. A subsequent A or T command causes preset values to take effect.
This can be useful when you wish to switch several switchers on a particular video field and thus have no time to send several messages. The D command is used to set up the switchers; then a series of short A commands to
each switcher initiates the switch.
The A and T commands both set all levels. D commands should be sent to
set the values of any level which are not to be the same as in the last A or T
command (source 1 initially).

Examples
In the following examples the Performer-HD address is set to 3C hex.
To preset level 3 of source 5 to destination 1, send these characters:
<CR>3C07D030501
In the example, 3C= <Adr>, 07=<Len>, and D030501= <Data>.
To take the preset values to the switcher output, send these characters:
<CR>3C01A
or, use the T command:
<CR>3C03T01
Performer-HD Instruction Manual 3-13
Page 46
Section 3 — Operation and Maintenance
To combine preset and take into a single command:
<CR>3C08D030501A
To query Performer-HD:
<CR>3C03Q01
If all levels were connected to source 3 and protected, the query response would be:
<CR>3C08SP000301
(Where level 00 indicates all levels)
If levels 1 and 3 were connected to source 10 and level 2 to source 1 and
unprotected, the response would be:
<CR>3C10SC000A01SC020101
The response contains two S commands. In the first, level 00 indicates
all levels are connected to source 10 (0A), but the second indicates that
level 2 is in fact connected to source 1 (takes precedence over the first
response). This technique reduces the number of characters in the response message by using the all levels value for the source connected
to the greatest number of levels followed by a specific message regarding sources connected to other levels.
If level 1 were connected to source 3, level 2 to 8, and level 3 not connected, the response would be:
<CR>3C18SP000301SP020801SP030001
The first S command specifies level 00, not level 01. The first S command in a status response is always for level 00 (all levels).

Performer-HD Remote
This protocol provides bidirectional communication between controlling
devices and crosspoint controllers on a single shielded twisted-pair cable.
RS485 standard is used, allowing a maximum of 32 communicating devices
on the bus. The protocol supports crosspoint matrices up to 4 levels, each
99x99. When this protocol is selected, Performer-HD forces the serial port
to 76.8K baud, 8 data bits, no parity.
When selecting this protocol, note that four variations are allowed depending upon the position of switch 2, segments 6 and 5. If 6 is OPEN, each Performer-HD level (video, audio 1, audio 2) is treated as a separate level in
the protocol (independently controllable within the switcher). If 6 is
CLOSED, all three levels are treated as a single level and switch simultaneously. (A breakaway can still be executed at the switcher integral control
panel).
If segment 5 is OPEN, the switcher will be in master mode. In master mode,
Performer-HD receives, executes, and responds to commands. If segment 5
is CLOSED, the switcher will be in slave mode. In slave mode, PerformerHD receives and executes commands but does not respond on the serial
bus. Slave mode is used when it is desirable to use multiple Performers assigned to the same level and destination number. The switchers will execute commands simultaneously but only a single Performer (set to master
mode) will respond with a tally message. Only one master mode Performer
may be on any one level/destination combination at a time. Otherwise,
garbled communications due to bus collisions will result.
Serial Protocol Descriptions
Source, Level, and Destination offsets which allow you to use multiple
master mode Performers on the same bus (but not the same level and destination) are determined by Performer switch S1.
Model 110 Compatible Protocol
Performer-HD may be used as a Model 110 Production Switcher peripheral. The Performer-HD audio selection automatically follows the switching
of the Model 110 Program Bus.
Performer-HD Instruction Manual 3-15

Section 3 — Operation and Maintenance
SMPTE 3245-E Protocol
Performer-HD may be controlled by a host computer using SMPTE 3245-E
protocol if the proper switches on the Performer-HD have been set. The
SMPTE 3245-E protocol is based on the following SMPTE standards documents:
■ Remote Control Systems for Television Production Equipment, Tech
3245-E, December 1984.
■ Remote Control Systems for Broadcasting Production Equipment: Sys-
tem Service and Common Messages, Supplement 1 to Tech 3245-E, June
1986.
■ Remote Control System for Broadcasting Equipment, Routing Switcher
Type-Specific Messages, Draft 0.1, July 1988.
Performer-HD has no non-standard communication sequences used with
the SMPTE ESCAPE sequence. If Performer-HD is selected and the SMPTE
ESCAPE character received, Performer-HD will enter the IDLE state and
call protocol error.
On reset, Performer-HD assigns itself to the SMPTE all-call group address
and clears all other group assignments.
Performer-HD does not make entries in the bus controller linkage directory. This must be handled by another device on the bus.
Performer-HD is a single virtual machine. Messages for selecting virtual
machine are NOT supported.
SMPTE standard (1984) shows the receive values for the ASSIGN state to
be 00-0F, 80-FF. This appears to be an error. It is 00-7F for deassignment and
80-FF for assignment.
SMPTE BUSY status (06H) is never returned by Performer-HD.
Protocol error is called when a protocol error occurs. Receive error is called
when a message we send is NAK’d by the bus controller or when a message
with a bad checksum is received.

SMPTE Message Processing
Message processing uses a buffer that can contain up to 200 bytes to hold
outgoing messages. All messages waiting to be sent are concatenated together into a single message block not surrounded by a Block command
(see below), which is placed in the message buffer and sent at the next message send time. The controlling machine must therefore be careful not to request too much information at one time, lest it overflow the buffer. If this
buffer does overflow before the bus controller polls and responds to the
router service request to send the data, the entire buffer contents are cleared
and replaced with a system service error (
overflow.
3-18 Performer-HD Instruction Manual
SERR) message indicating buffer
Page 51
Serial Protocol Descriptions
SERR (08, System Service Error) is also sent when a system service message
is encountered (byte code between 00 and 1F) that Performer cannot handle, or when a message that it can handle contains a bad data item.
CERR (29, Common Error) is sent when a common message is encountered
(byte code between 20 and 3F) that Performer cannot handle, or when a
message that it can handle contains a bad data item.
Any
SERR and CERR that is generated as a result of a bad value in the mes-
sage or inability to perform the message function contains all data bytes of
the message, from the command keyword up to the data byte at which the
error was detected.
Since the type-specific messages do not have an error response message,
CERR is sent when a type-specific message is received that has an error in it.
IFRE (32, Information Field Item Response) is sent in response to a READ
message or a previous UPDATE request.
STUR (40, Startup Response) is sent when the router is powered up or reset.
The SMPTE standard document, on page 37, shows in Figure 11c that a
Block keyword can surround a group of messages, and that additional messages can both precede and follow the block of data in the same supervisory-level message block. The SMPTE Supplement 1 to 3245-E says, on page
15 under the description of the Block command, that the command shall be
used on every occasion where message concatenation is employed. These
two seem to conflict with each other. Performer sends outgoing messages
without a Block command, and parses incoming messages with or without
Block commands.
The Specific Mute message definition does not explicitly say that more than
one information field can be supplied, wrapped in a Begin/End construct.
However, since this is the usual definition in other parts of the standard,
Performer-HD allows that construct.
Likewise, the Preset message definition does not explicitly say that more
than one information field name/value pair can be supplied, wrapped in a
Begin/End construct. This construct is allowed by Performer.-HD
The following I/F names can be used in a Preset message: Matrix, Level,
Source, and Destination pointers. In particular, note that sources-to-destination and destinations-to-source may not be used.
The Preset message will not allow the Matrix, Level, Source, or Destination
pointers to be set to values that are invalid for this matrix. The SMPTE standard does not say whether invalid I/F values can be set or not.
Performer-HD Instruction Manual 3-19
Page 52
Section 3 — Operation and Maintenance
The SMPTE standard does not say what should be returned for the Level
Configuration information field if the matrix pointer or level pointer is set
to an invalid value. Since Performer does not allow invalid values to be set,
this is not a problem.
The Level Configuration information is of limited usefulness because there
is no message for determining the allowed limits of the matrix pointer and
the level pointer. The router requires the matrix pointer to be 0 and the level
pointer to be between 0 and 2 (wildcard values are allowed too).
A single I/F Item Response message is sent containing all values (wrapped
in Begin/End) requested via Read or Update messages since the last such
response message was sent. Two separate Read messages back to back will
not produce two I/F Item Response messages containing the separate data
items, but rather will produce a single message containing them.
The Read message will result in all the values being read simultaneously,
just as with the SRDR (3F/11, Simultaneous Read Response) message.
The destinations-to-source and sources-to-destination information fields
are sensitive to whether or not the level, source, and/or destination pointers are set to the wildcard values (FF, FFFF). If so, reading these information
fields results in multiple I/F response values for these I/Fs; one for each
wildcard replacement combination. The SMPTE spec is a bit unclear about
how the wildcarding should apply, but this seems to be the correct way.
It is not possible to read the value of a single crosspoint, only of entire rows
or columns of the crosspoint matrix (using sources-to-destination or destinations-to-source). Setting the matrix, level, and destination pointers, and
then reading the source pointer, will not give the source connected at that
matrix/level/destination. Instead, it will give the current value of the
source pointer.

digital video signal as defined by SMPTE
274M. 1080i signals have 1920 horizontal
pixels per line, 1080 active lines, and are interlace with two fields per frame.
720p
An abbreviated term for a high definition
digital video signal as defined by SMPTE
296M. 720p signals have 1280 horizontal
pixels per line, 720 active lines, and are progressive scan.
AC-3
A transport mechanism for multi-channel
audio, as defined by ATSC specification
A-52. AC-3 is used as the audio delivery
system for DTV programs.
Analog
Use of a continuously variable signal to
convey information. Conventional Definition Television (NTSC, PAL, etc.) is analog.
Aspect
The ratio of a picture’s horizontal and vertical dimensions when correctly displayed
(16:9 for example).
Bit Rate
The number of bits per second passed from
one point to another.
Black Burst
See Color Black.
Color Black
An analog synchronizing signal consisting
o f horizontal, vertical, and color synchronizing information. This signal produces a
black screen on a Conventional Definition
television monitor.
Component Video
A video signal that keeps color and luminance information separate. RGB; Y, R-Y,
B-Y; and Y, Cr, Cb are examples of component video.
Composite Video
An encoded video signal that combines
color information with luminance information. NTSC, PAL, and D-2 are examples of
composite video.
Conventional Definition Television (CDTV)
The analog NTSC, PAL, SECAM, and related television systems.
ATSC
Advanced Television Systems Committee,
developer of the HDTV standards recommended to the FCC for adoption.
Auto Ranging
AC input range selections of 90 to 132 VAC
and 180 to 260 VAC are automatic.
Performer-HD Instruction Manual Glossary-1
Delegate
To assign panel controls to a particular operating function. Some panel controls (buttons, knobs, joystick) can affect more than
one function. The operator can choose an
alternative function by delegating the panel controls to that function (typically by
pressing or holding down a panel button).
Page 56
Deserializer
Frame Rate
A device that converts serial digital information to parallel.
Digital
Use of discrete signal levels that correspond to logic 1 or 0 to convey information.
Digital Television (DTV)
The digital television broadcasting system
that replaces analog television. DTV includes both HDTV and SDTV broadcast in
digital form using MPEG-2 compression
for video, AC-3 compression for multichannel audio, and 8-VSB modulation for
digital terrestrial transmission.
Field
One scan of an interlaced video image. In
interlace systems (1080i, for example) two
fields are required to make a complete picture (video frame) because alternate lines
are scanned. Note that on progressive systems (720p, for example), one scan contains all the image information, and so this
single scan is called a frame rather than a
field.
Field Replaceable Units
Components of a frame, matrix, switcher,
etc. that can be removed and replaced with
a spare. Field Replaceable Units are not repaired in the field and are sent to designated repair depots.
Frame
One complete scan of a video image. For
progressive video, all the lines in a frame
are scanned successively from top to bottom. For interlace video, alternate lines are
scanned, and so a frame containing all the
picture information consists of two fields.
The number of frames presented per second. Note that for interlace systems the
frame rate is half the field presentation
rate.
Framestore
A device that captures, saves, and outputs
a still video image.
GSC
Global Serial Channel
High Definition Television (HDTV)
Television with a resolution approximately
twice that of Conventional Definition Television in both the horizontal (H) and vertical (V) dimensions and a picture aspect
ratio (H x V) of 16:9.
Interlace
A system of video scanning where the odd
and even numbered lines of a picture are
presented consecutively as two separate
interleaved fields. The two fields required
to make a complete picture are called a
frame.
Jitter
An undesirable variation in the timing of
transitions in a digital signal.
MPEG-2
A video compression mechanism employed by DTV to fit the digital data into
an existing 6 MHz bandwidth transmission channel.
Parallel Digital Video
(1) Passing multiple video data bits in parallel groups along a collection of wires
(called a bus). High Definition parallel digital video (1080i and 720p) typically uses
two parallel 10 bit buses (20 bits total) operating at 74.25 MHz. In comparison, Stan-
Glossary-2 Performer-HD Instruction Manual
Page 57
dard Definition parallel digital video
employed within a device typically uses
two 10 bit buses operating at 13.5 MHz.
(2) For parallel interfaces between devices
using multi-pair cables (now obsolescent)
the two buses are combined for Standard
Definition video into one 27 MHz interface
(SMPTE 125M). The two buses remain separate for High Definition parallel interfaces
using multi-pair cables (SMPTE 274M).
Pixel
A picture element. A pixel is a digital sample of the color intensity values of a picture
at a single point.
PECL
Positive Emitter Coupled Logic
Progressive
Scanning every line of a video picture in
sequential order to create a complete picture. Each complete scan is a frame.
Sync
(1) General term for a synchronizing signal
or signal component. Digital systems generally employ an analog external timing
reference signal (such as color black or trilevel sync) to synchronize different pieces
of equipment. Within the digital signal itself, however, synchronizing information
is carried by special digital codes inserted
at the beginning and end of each active
line.
(2) In analog television systems, sync is the
portion of the video signal which occurs
during blanking and is used to synchronize the operation of cameras, monitors,
and other equipment. Horizontal sync occurs within the blanking period in each
horizontal scanning line, and vertical sync
occurs within the vertical blanking period.
A color black signal is often used for synchronizing different pieces of analog
equipment.
Television
Reclocking
The process of clocking the data with a regenerated clock.
Serial Digital Video
Passing video data bits in serial form (one
bit after another), along a single wire. High
Definition serial digital (1080i and 720p as
defined by SMPTE 292M) operates at 1.485
GHz (2 x 74.25 MHz x 10 bits). In comparison, Standard Definition serial digital video (SMPTE 259M) operates at 270 MHz (2 x
13.5 MHz x 10 bits).
Serializer
A device that converts parallel digital information to serial.
Standard Definition Television (SDTV)
A digital television system with quality approximately equivalent to that of NTSC.
An electric transmission and reception of
transient visual images, usually together
with associated sound. Television generally involves the broadcast of information
from one location to many locations.
Tri-Level Sync
The synchronizing portion of the HDTV
signal, as defined in SMPTE 240M. Tri-level sync signals (which are analog) can be
used to synchronize different pieces of
HDTV equipment.
Video
An electric signal that carries transient visual images. Video generally involves the
movement of visual information from a
single source location to a single destination, or to a small number of destinations.
Many different types of analog and digital
video signals exist.
