How To Use This Manual
If you are an experienced switcher operator, you may choose to go directly from Startup to operating the switcher, and refer to the Control Panel Descriptions section in the manual only when you need to know more about the operation of a specific control. Experienced operators may also wish to refer to some parts of Section 4 — Switcher Operations, to learn about topics such as Chroma Keying, Effects Send, and how to set up keyframes (a set of switcher parameters stored in an E-MEM register).
If you are not an experienced operator, you should read or scan this entire guide. You should first read Section 1 — System
Overview and Section 3 — Switcher Concepts to learn switcher
“basics.” Next, review the Startup and Configuration section to get a feel for the switcher setups and configurations. Finally, practice with and use the task-oriented procedures presented in the Switcher Operations section that apply to your operations on the switcher.
To quickly locate specific areas of interest, refer to the “master” Table of Contents in the front of the manual, or the “local” Table of Contents located at the front of each manual section.

System Overview

1
This section presents a general description of the Grass Valley Products Model 2200-2 Production Component Digital Switching Systems.
The Control Panel and Signal Processor descriptions provide a basic knowledge of the Model 2200 basic architecture.

Basic Architecture

The Model 2200 is a component digital switcher . It can manipulate CCIR 601 serial component digital and analog component video and key signals through the use of 10-bit digital processing. An Analog Chroma Keyer Input Module is also available.
The Model 2200-2 provides two full function mix/effects subsystems. Up to 32 serial digital inputs which can be mapped to switcher crosspoint buttons and used as video and/or key sources. Internal sources are also available, such as Black, Masks, Color Bars, and Background.
Effects animation functionality may be used to build and run a sequence of effects. Effects are stored in E-MEM registers as a list of “keyframes” (see the Operation Reference manual, for a definition of Keyframes). The E-MEM register operations are used to learn, recall, copy, and link effect registers.
The layout of the Control Panel is logically structured for efficient control of video signals.The Menu Display Subpanel allows quick changes to switcher system parameters.

Section 1 — System Overview

Physical Description

The switcher consists of three main areas: the Control Panel, the Signal Processor Frame, and the Frame Power Supply (see
Figure 1-1) The electronic circuitry for the Model 2200 is contained
on circuit boards and modules in the Signal Processor Frame and Control Panel.

Signal Processor Frame

The Signal Processor Frame is a large rack-mounted unit that houses the system Controller, Mix/Effect logic and processors, Input/Output interfaces, and Expansion circuit modules.
In addition to the basic system, a typical system may have several options such as Chroma Keyers, Secondary W ipe Generators, and Effects Send. Most options are available as circuit boar d modules (or submodules called “mezzanine” boards) that are installed in the Signal Processor Frame.
1-4
Refer to the Model 2200 complete description of the Signal Processor.
A main pr ocessor and separate M/E processors reside within the Signal Processor Frame. Since each M/E has its own processor, failure of one processor does not disable the entire switcher. Individual effects can continue to operate independently in a limited capacity.

Power Supplies

Two power supplies are used in the basic Model 2200 system: a control panel power supply, located in the control panel tub, and a 19" rack mount power supply used by the Signal Processor Frame. Optional Redundant power supplies are available.

Section 1 — System Overview

Video and Key Inputs and Outputs

Inputs
Two types of input modules may be installed in the Signal Processor Frame to suit the needs of your installation. The following types of input modules are available.
NOTE:
Each of the serial or analog inputs can be treated by the switcher
as either a video input or a key input.
Serial Digital Input Module – provides 8 inputs, auto-timed
within a range of ±18 microseconds. Two modules are supplied in the standard configuration. Two modules are available as options. With four modules installed ther e ar e 32 inputs available.The modules are located in Bay C.
Chroma Key Input Modules (optional) – Either one or two Chroma Key Input Modules may be configured. These modules allow full bandwidth chroma keys. Each module has two inputs.

Section 1 — System Overview

Functional Description

General Overview

Figure 1-3 shows a simple video flow diagram for the Model 2200.
Video and key signals enter the input modules of the Model 2200, which consist of component analog and/or component serial digital formats. The analog signals are converted to digital format, and all inputs are timed and conditioned.
The digital signals are then passed to the V ideo and Effects Section where keying and mixing take place. This section also provides effect modifications, such as wipes and keyframing, that can be applied to selected inputs.
In the Output Section, digital video and key signals are routed to the Serial Digital Output Modules and the optional Analog Output Module before leaving the Signal Processor.
1-10

Video Processing

Input video and key signal selections are made by the Crosspoint Matrix under control of the system Controller, according to operator assignments entered via the Control Panel.
In addition to primary (external) video, secondary (internal) sources such as Masks, M/E re-entry video, and optional Effects Send are available as inputs to the crosspoint matrix.
Any suitable component digital signal from the Crosspoint matrix may feed the Chromatte™ Chroma Keyer Module option. Analog Component signals may also be used as Chroma Key sources.
Keyers in each Mix/Effects bank provide outputs to the Mixer Interface crosspoints. These outputs may be sent outside the switcher for external processing, or may be routed to the M/E mixers and wipe generators. The Effects Send outputs can be directed to the Framestore option for image capture.
Functional Description
Each M/E has two keyers and two background buses (A and B) as inputs. In standard mode, Keyers 1 and 2 can be mixed into a composite video and key which can be forwarded to the output, or M/E 1 can be reentered into M/E 2. In layered mode, Background Buses A and B are also used as keyers.
Preview capability allows monitoring of sources at many points in the signal flow. You can preview video from the M/E mixers, switched preview bus, or mask bus.
Eight GPI inputs are provided. You can assign each of the GPI inputs via the GPI Input Menu to perform a specific function when triggered.
The editor interface consists of an asynchronous RS-422, 38.4K baud serial communications port, managed by a communications processor. Refer to the Model 2200/3000/4000 manual for information on software functions and protocols observed by the editor port.

Section 1 — System Overview

Description of Options

The following options are currently available for the Model 2200 switcher. For more details on these options, refer to the appropriate subpanel descriptions later in this manual.

Chromatte Advanced Chroma Keyer

Each foreground keyer in M/E 1 and M/E 2 has access to an optional component chroma keyer. Either an internal component digital signal or an external component analog signal from one of the Chroma Key Input Modules can be used as the chroma key source. Color background suppression, foreground suppression and shadow processing are included as features.

BORDERLINE Key Edge Generation

BORDERLINE® Key Edge Generators are available for each keyer in the switcher. The Borderline feature is implemented as a submodule that plugs onto the Keyer module of any M/E.
1-14
Each Borderline generator supports 1, 2, or 3 line wide borders for border and outline modes and 1 to 6 line wide edges for shadow and extrude modes. Fill within the key edges may be either video or matte.

Secondary Wipe Generator

A Secondary W ipe Generator option provides a second pattern for each M/E. The Secondary Wipe Generator Submodules mount on the M/E 1 and M/E 2 Mix/Wipe Modules.

Effects Send

Effects Send provides a method of integrating digital effects devices into the switcher mix/effects system. Up to two send channels can be used to route the video and key from an M/E to and from an external digital effects system.

Look Ahead Preview

Look ahead preview processing is provided for both M/Es with this option. Submodules mount on the M/E 1 and M/E 2 Mix/Wipe Modules.

Tally Relay Frame

The Tally Relay Frame provides external tally outputs that reflect the switcher status. A rear-panel interconnect board provides the relay contacts on two connectors for on-air T ally A and on-air Tally B. The frame can hold up to three Tally Modules. Pinouts for the Tally connectors are given in the Installation section of the Model
2200 Installation and Service manual.

Section 2— Startup and Configuration
Using Field Dominance
If the Model 2200 output is going to be recorded onto tape that will later be edited along with other tape, it is important that changes take place consistently on the same field. They can occur on either Field 1 or Field 2 of the frame, but need to be on the same field every time. If this is not done, there will be a “flash” at the edit in the resulting taped video.
With FIELD 1 selected as the dominant field, if a change takes place just prior to Field 1, the change will become effective at the beginning of Field 1. But if the change takes place prior to Field 2, the change will be delayed by one field so that it also becomes effective at the beginning of the next Field 1. This way, all changes will be synchronized to take place at the beginning of Field 1.
Similarly, if changes that take place prior to Field 1 would be delayed until Field 2.
If you are recording the switcher output on video tape and will be doing post-production editing of the tape, it is recommended that you set Field Dominance for a specific field (either FIELD 1 or FIELD
2
), and leave it at that setting. This will ensure that all changes will
take effect consistently on the same field.

If an Editor or a GPI trigger initiates one of these functions, it will produce the same effect as a control panel change. That is, the initiation of any of these functions will be delayed until the beginning of the selected dominant field.
Software Setup
The MATTE GEN LIM button is used to choose the matte generator chroma limiting algorithm. The selections are:
XMITABL – Prevents the total signal (luminance and
chrominance) from exceeding the NTSC transmission standard.
VALID RGB – Limits colors to those which generate red,
green, and blue values within the 0 to 100% range.
BOTH – Selects a valid RGB color limiter which also
prevents the encoded signal envelope from exceeding NTSC transmission level. This is the system default mode.
NONE – Turns off all algorithm methods for matte
generator limiting.

Configuring Switcher Inputs
Primary video and key inputs to the switcher are numbered 1 through 64. Any of these inputs can be treated as either a video signal or a key signal.
Each input, including Black and Background, can be mapped to any vertical column of source select (“crosspoint”) buttons.
NOTE:

Internally-generated sources (black, backgrounds, mask, etc.) are also available for selection on the crosspoint matrix.
Thirty-two sources may be assigned at one time to the crosspoints — 16 unshifted and 16 shifted selections. During the installation procedure, each of the 32 input buses is assigned a video signal, a key signal, and a chroma key signal.
All inputs are defined by function, name, crosspoint, input number, and signal format.
Y ou may determine the input assignments and the characteristics of the input signals through the use of the Configuration submenus, as described in the following procedures.

DPM Configurations
Digital Picture Manipulators (DPMs) are external video devices connected to the switcher. In this discussion, reference is also made to DPM levels, which are E-MEM levels into which DPM­associated information is learned. The combined system capabilities of the switcher and DPMs depend on:
The video connection
The capabilities of the DPM
The control connection
It is not necessary to have a control connection from the switcher to a DPM; however, the highest level of system integration is achieved where there is a control connection.
The Video Connection (Aux Buses and Return Inputs)
A normal video signal path consists of an aux bus output fr om the switcher feeding a DPM input and the DPM output returned to a switcher input which is mapped to a switcher source select button.
2-42
The video path through a DPM introduces a video delay into the system. For example, Kaleidoscope introduces a 2-field video delay.
NOTE:
If the video delay is not set correctly, ther e will be a glitch in the
video upon entering Effects Send mode.
There are four steps in configuring the video path:
Aux buses are assigned to DPMs using the DPM Map Aux
Buses Menu
Return input connections are configured using the DPM Map
Inputs Menu
The mapping of a return connection to a crosspoint is done
using the Configuration/Map Inputs Menu
The video delay is set using the DPM Setup Menu
Software Setup
The system defaults to all aux buses being part of the MISC E-MEM level. When an aux bus is configured for use with an external DPM, its settings are no longer saved in the MISC level but are saved in the relevant DPM level when an E-MEM register is learned. Information (such as aux bus crosspoint selection) is learned for each DPM on separate E-MEM levels.
In cases where it is not desirable to have an aux bus selection learned/recalled on the MISC level, it is possible to configure the aux bus to a DPM level (such as DPM 4) and never enable that level. An example would be if the aux bus were controlled by a Remote Aux panel.
DPM Capabilities (Fixed and Pooled)
The characteristics of the DPM are configured in the DPM Setup Menu. The first choice to be made is selection of DPM TYPE from
NONE, KSCOPE, OTHER POOL
The DPM TYPE of NONE indicates that there is no external DPM device used for the particular DPM level. However , it can also be used for cases where aux buses are assigned to a DPM level, but there is no physical device, no return signal, and no control connection (for example, an aux bus dedicated to feeding a video monitor).

, or OTHER FIXED.
Both KSCOPE and OTHER POOL are selections for pooled devices. A pooled device is one which provides acquisition of logical
channels from a pool of physical channels.
Kaleidoscope is a pooled device. As an example, consider a Kaleidoscope having 5 physical channels named A, B, C, D, and E. The pooled channels are shared by different users. A user may build a Kaleidoscope effect using 3 channels. On one day he may acquire physical channels C, D, and E as logical channels 1, 2, and 3; on another day he may acquire physical channels B, C, and D as logical channels 1, 2, and 3. The same effect will perform identically on both configurations since the operator’s view of the
1. OTHER POOL is reserved for future use. It is for DPMs other than Kaleidoscope which are pooled and use CPL to communicate.
2-43
Section 2— Startup and Configuration
system is the logical arrangement of channels (1, 2, 3), not the physical channels used.
In systems with multiple DPM channels, it is desirable to have a predictable relationship between aux buses and DPM channels (e.g., aux bus 1 feeding DPM channel 1, aux bus 2 feeding channel 2, etc.). It is also desirable to have a particular switcher crosspoint button always select the same DPM channel return input. For a fixed device (such as the DPM-700) this relationship is achieved by cabling alone. For a pooled device, such as Kaleidoscope, the Model 2200 achieves predictable DPM channel routing by maintaining an extra level of mapping between physical and logical DPM channels. This mapping, termed Switcher Input Routing and Switcher Output Routing, is discussed on the following page.
DPM TYPE of OTHER FIXED or NONE (DPMs which are not pooled
For and do not have Input and Output Routing), the CHANNEL ROUTING selection should be OFF.
Kaleidoscope changes its logical-to-physical channel mapping, depending on the order in which channels are acquired from its pool. Switcher output routing maps a physical aux bus to a logical aux bus so that the logical aux bus number corresponds with the DPM’s logical channel.
2-44
The Aux bus button selection made on the switcher control panel is always a logical aux bus; however, unless Kaleidoscope is connected, Logical Aux Bus 1 always corresponds to Physical Aux Bus 1, etc. (The current mapping of physical-to-logical DPM channels is displayed in the DPM Map Inputs Menu.)
It should be noted that the switcher supports only one pooled device. Also, the pooled device must be cabled so that the first physical aux bus is connected to the first physical channel. In the example in Figure 2-3, Physical Aux Bus 1 is connected to Kaleidoscope Physical Channel A, Bus 2 to Channel B, and so on.

Figure 2-3. Example of Connections for a Pooled DPM
For a particular studio session, three Kaleidoscope channels could be acquired from the pool in the order D, E, A, which would be logical channels 1, 2, 3. This mapping information is passed from the DPM to the switcher via the control connection. Switcher output routing ensures that the logical channels 1, 2, 3 appear to the user on logical aux buses 1, 2, 3 and switcher input routing ensures that DPM logical channels 1, 2, 3 appear on the crosspoints configured for these logical channels. For the above configuration, the selection of CHANNEL ROUTING in the DPM Setup Menu should be set to BOTH.

2-45
Section 2— Startup and Configuration
There are circumstances wher e output routing is not desirable. For example, the DPM may have more than 5 channels. In that case, a router or patch panel may be inserted between the switcher and Kaleidoscope (Figure 2-4). In this example, switcher output routing is turned off, so the menu selection for CHANNEL ROUTING in the DPM Setup Menu should be set to SWR IN. This still provides the return video from the switcher being on a consistent crosspoint.

Software Setup
Control Connection
Three forms of control connection to the DPMs are supported. These are
CPL (Control Point Language)
PBusII (Peripheral Bus II)
GPIs
Control Point Language — CPL is the communication protocol used to couple the switcher and Kaleidoscope. One of its uses is to convey the physical-to-logical channel mapping information described previously. It is also used for run control of effects, aux bus selection (including front/back switching) and tally.
DPM TYPE is set to either KRYSTAL or KSCOPE in the DPM Setup
When Menu, CPL is automatically invoked. PORT ASSIGN should be set to PORT A1.
Also, when either KRYSTAL or KSCOPE is selected as the DPM TYPE, aux bus control is automatically assigned to Krystal/Kaleidoscope. With Krystal/Kaleidoscope controlling the aux buses, when a source button is selected on the Krystal/Kaleidoscope panel, that source button is also selected on the switcher for that aux bus, and vice versa. So an effect running on Krystal/Kaleidoscope can cause the switcher to select different crosspoints. This is the mechanism used to achieve front/back switching.
All control connections have an associated control delay. The
CONTROL DELAY in the DPM Setup Menu should be set to 6 fields
when the DPM TYPE is set to either KRYSTAL or KSCOPE. When any other type of DPM is selected as the DPM TYPE, the Model
2200 Switcher controls the aux bus.

Section 2— Startup and Configuration
Peripheral Bus II (Port A3 Only) — PBusII is used for r un control of
effects using triggers. With current software, PBusII triggers are learned into the MISC E-MEM level. For example, when using PBusII as the control connection for a DPM-700, the following should be set in the DPM Setup Menu:
PORT ASSIGN = NONE
CHANNEL ROUTING = OFF
GPIs—Both input and output GPIs may be used as triggers as part of the control interface between the DPM and switcher. Depending on the nature of the DPM, GPIs can be used for effect recall and run control, source selection, and tally information.
Configuring the DPM Interface
Set up the DPM type, port assignment, channel routing, video delay, and control delay as follows:

Since the process of unshaping the video signal results in dividing the video signal by its key, level errors, especially ar ound black, may produce extreme signal levels where the key is at or near zero.

Switcher Concepts

This section describes a few basic concepts that you should know before you operate your switcher. You might be tempted to skip over this section, especially if you are an experienced switcher operator . Nevertheless, we suggest that you to br owse it anyway, because it explains operating concepts that help you more fully understand how the switcher works.

Section 3 — Switcher Concepts

Clear Working Buffer

The Current Working Buffer (CWB) is an area of system memory that stores the current switcher state. That is, it tracks the settings of switch and variable control functions on the control panel, as well as those of many switch and control functions set in the menus.
When an E-MEM recall is done, the data in the recalled E-MEM Register is loaded into the Current Working Buffer, which sets the switcher parameters of all enabled levels to match those stored in the first keyframe of an E-MEM effect.
The GVP Factory Default of the CWB is a set of switcher parameters stored in memory that may be used to return the switcher to a known set of conditions. Some of these parameters may be periodically updated with software updates.
The User-Defined Default buffer is battery-backed RAM that may be used to store a set of parameters tailored to your requir ements and preferences. At power-up the information in the User­Defined Default memory is loaded into the Current Working Buffer, which sets the initial state of the switcher.
3-2
At any time, the User-Defined Default values may be restored to all enabled areas of the switcher by pressing the CLEAR WORK
BUFR
button on the E-MEM Subpanel.
The data in the User-Defined Default Buffer may also be modified at any time through the Configuration/User Prefs/Define Defaults Menu.
