Making Complex Tasks Simple

Regardless of the task, Sony has the right digital switcher for the application at hand. And whether the switcher is large-scale, mid-range, or compact in size, one important factor is constant across the product line — Sony switchers have the power to make complex tasks simple.

That benchmark principle holds true with the new DVS-7250. Here are just a few examples:

• DME-LINK™ — the ability to run the DME-3000 or DME-7000

effects timeline from the switcher. This function simplifies operations with a simple push of the fader or the triggering of an E-File™.

• Processed Key — the ability to compose a key within the DVS-7250,

route it to an external device (such as the DME) for processing, and re-enter it in the same DVS-7250 keyer. This feature reduces complex patching to a simple button press.

• System Integration — provides powerful production and editing tools

in conjunction with the BVE-9100, BVE-2000, and DME-series effects devices. Through status reporting and the editing system’s ability to learn switcher functions, this high level “system” function greatly simplifies the editor’s day-to-day requirements.

• Fingertip Menus — an extremely simple and logical method of

accessing menus. Simply double-press any control panel button that has an associated menu, and the system instantly jumps to that location on the display. Functions with associated menus such as keying, color background, frame memory, and timeline control are at your fingertips, without time-consuming menu navigation.

• Router Interface — the ability to control a Sony DVS-B Series

routing switcher directly through the switcher’s integral display. This feature places up to 128 sources at your fingertips, with the superb (and ultra-efficient) capability of storing router information along with switcher setups and snapshots.

• Peripheral Interface — using a widely adopted industry standard

(Grass Valley Peripheral II), the DVS-7250 can control digital effects devices, still stores, and character generators with convenience.

• Familiarity — the DVS-7250’s operating style simplifies the learning

curve and enhances creativity at every turn.

As you review the DVS-7250 feature descriptions that follow, keep in mind how Sony’s overall digital switcher principle rings true — making complex tasks simple.

Basic Tools

SONY

This section describes basic DVS-7250 features used in day-to-day production and post-production.

Control Panel

The DVS-7250 offers two different control panels. Each is compact and modular, and similar in design and layout to the larger DVS-7000 series, but with two M/E (mix-effects) banks rather than three, plus a powerful program/preset bus.

• The “American Style” panel (BKDS-7026) features staggered

FlexiPad control for each M/E, in a layout familiar to all freelance and staff technical directors. The compact FlexiPad allows quick learning and recall of snapshots, user DME functions, and user wipe functions.

• The “Euro Style” control panel (BKDS-7025) provides a source name

display plus in-line FlexiPad control on each M/E.

Regardless of the selected panel, the DVS-7200’s streamlined architecture includes two keyers and a color background generator on each M/E and the program/preset bus. As a fully-loaded system, six simultaneous key layers are possible.

Like all Sony digital switchers, the DVS-7250’s control panel is engineered for simplicity and ease-of-use. A large-scale display screen offers easy access to operational parameters, adjustments, and setup functions. Dedicated controls (with associated displays) are provided on each M/E plus program/preset, offering convenient access for keyer adjustments.

The control panel also supports a variety of optional sub-panels for memory recall control, DME control, DSK control, and E-File control. All sub-panels are identical in size, allowing their in-panel locations to be customized as required. Optional sub-panels can also be mounted external to the panel, using a BKDS-7075 Remote Adaptor.

The control panel’s benefits are as clear as the design — familiar streamlined operations, comfort, and flexibility.

Input Flexibility

The DVS-7250 can be equipped with 12, 24, or 36 primary inputs and up to four component analog chroma key inputs. For flexibility, all SDI inputs can be switched (from the panel) between component digital (4:2:2) and composite digital (4fsc) operations. This versatile system allows you to edit, for example, with component DVW-500’s in one session and composite DVR-20’s in the next — seamlessly.

By adding the BKDS-7110 “Mother Board,” you can also customize your input configuration with a mix of analog composite and serial digital input modules — up to three BKDS-7110 boards can be installed, and up to 12 input modules can be installed per board, in any combination. Even though the switcher’s internal processing is fully digital, the analog composite input modules provide a convenient gateway for existing composite equipment.

DVS-7250 • Product Guide Features and Benefits •• 5

SONY

Note that with the hybrid composite analog/digital configuration, when you switch to component digital operations, all composite analog inputs are temporarily disabled.

6 •• Features and Benefits DVS-7250 • Product Guide

SONY

The bottom line is that the DVS-7250 is not restricted to one or two input configurations. You have the flexibility to configure the precise system to suit the customer’s current requirements — and expand when future needs arise.

V-Proc

Because input configurations change from day-to-day, all inputs have an autotiming window with an adjustment range of ± .4H. For simplicity and convenience, the “V-Proc” (Video Processing) feature allows adjustment of each input to compensate for common errors in image acquisition. Adjustments are provided for the following parameters:

• ± 200% adjustment range for video (4:2:2 / 4fsc)

• ± 200% adjustment range for luminance (4:2:2)

• ± 200% adjustment range for chrominance (4:2:2)

• -7.31 to +109.64 IRE adjustment range for black level (4:2:2)

• -42.86 to +140.00 IRE adjustment range for black level (4fsc)

• ± 180° adjustment range for hue (4:2:2)

V-Proc actually provides a greater control range than a TBC.

Output Flexibility

The DVS-7250 offers an impressive array of outputs:

• Four Program

• One Preview

• One Clean

• Fourteen Auxiliary outputs, including one Edit Preview

• Two M/E 1

• Two M/E 2

Best of all, by selecting the desired combination of output modules (BKDS-7161 Analog Composite or BKDS-7162 Digital Output), you can customize the format of each output listed above.

Whether you need a mix of composite analog and digital Aux bus outputs, or an alldigital system, the DVS-7250 makes it easy. Compared to switchers with fixed output configurations, the DVS-7250’s flexibility literally adapts to the production or post production situation at hand.

Effect Keyers and DSK

In the DVS-7250, two powerful effect keyers are standard (per M/E). Up to two DSKs (Down Stream Keyers) can also be added. A variety of creative key “types” can be selected, as follows:

• Luminance — a high-gain key that derives the “hole-cutting”

information from the full range of source luminance values.

• Chroma — a key in which the hole-cutting information is derived

from a color rather than from a video level.

DVS-7250 • Product Guide Features and Benefits •• 7

SONY

• Linear — a key that takes advantage of independent key signals

provided by external devices such as character generators. Linear keyers have increased sensitivity to the key signal gain.

• Clean — a key that takes advantage of “shaped” video provided by

devices such as digital video effects. Whereas a linear key is multiplicative in its ability to cut a hole, a “clean” key is additive.

• Pattern — a key that uses a wipe pattern (and all active pattern

modifiers) to generate a key signal.

Keyers truly make the difference in switchers. There’s rarely a production or commercial today that doesn’t involve multi-layer keys — it’s a requirement that can’t be overlooked in switcher design. The DVS-7250’s key processing capability is powerful, yet it’s also simple to understand and operate. You can express your creativity and make a storyboard come true — without getting lost in menus.

Key Edge Adjustment

One aspect of the DVS-7250’s high quality key processing is the ability to fine tune and optimize the key signal — independent of the “fill.” Through the use of oversampling, the key signal’s width can be modified in sub-pixel units. Edges can be trimmed to add dimension and overall realism, and adjustments can be performed independently to the left and right key edges. Furthermore, because the process follows the edge itself, even irregularly shaped key signals benefit from Key Edge processing.

From simple mattes to complex chroma keys, the DVS-7250’s Key Edge processing is another simple tool that yields visually powerful results.

Enhanced Wipe Generator

With the BKDS-2070 option, additional patterns (including matrix wipes) are added. These include Star, Heart, and the popular “Diamond Dust” wipe. The enhanced patterns can also be combined with the primary patterns — enabling you to create new custom wipes.

Snapshot, Effects Memory, and Storage

As the natural by-product of computer controlled switchers, the ability to store and recall control panel snapshots has become a fundamental production requirement.

Clients come back to change things — sometimes more than once! Producers like their keys set up just one way — and always that way. And TDs (technical directors) like to work with special and often highly customized setups — even if the previous TD had a completely different control panel setup.

These typical situations are a breeze with the DVS-7250. TDs can store and recall up to 99 “snapshot” memories from the Master E-File panel or M/E FlexiPad, and recall up to 32 snapshots as dedicated functions from the optional Shot Box panel. You can even transition between snapshots. The snapshot data (as well as setup and effects data) can be archived on an integral floppy disk for long term storage. For live use or post, snapshots are directly accessible through the Master E-File panel, the Memory Recall panel or the Shot Box panel.

SONY

Superior Editor Interface

The DVS-7250 communicates with editing systems from most major manufacturers via serial interface, including Sony’s BVE-2000 and BVE-9100. With most editors, a variety of basic editor-switcher control modes are available, including:

• Crosspoint assignment.

• Pattern selection.

• Transition and duration control.

• Basic switcher “learn” capability, with storage in the editor’s EDL.

• GPI control for auto-transition and memory recall functions.

With the BVE-9100 specifically, Sony’s superb status reporting adds many advanced modes:

• Precise Jog/Shuttle positioning of the switcher timeline.

• Advanced switcher timeline learn functions, with switcher status and

transition data stored in the editor’s EDL.

• Control of both switcher and DME keyframe data.

• Using the BKE-9402 Programmable Control Panel, virtually

everything that can be controlled or adjusted in the switcher can be adjusted from the editor.

It’s another aspect of Sony’s system integration that contributes to the simplicity of working with a Sony system — making complex tasks simple.

Router Interface

Switchers like the DVS-7250 typically have a limited group of inputs available on the panel — facilities, however, typically have a very large pool of input sources controlled by a routing switcher. Depending on the daily requirements of a production, the TD is constantly called upon to change the array of switcher inputs.

In the past, this function was performed by manually operating external control panels. Now, with the DVS-7250, you can control a Sony DVS-B Series routing switcher directly from the DVS-7250’s display — allowing complete flexibility with crosspoints, input assignments, and the switcher’s 14 auxiliary buses.

Depending on routing switcher’s configuration, up to 128 sources can be assigned to the switcher’s 36 primary inputs and four analog component inputs. Router information is also stored with switcher setups and snapshots — which in turn provides operator convenience, efficiency, and highly precise effect recall functions. And when the DVS-B Series router and DVS-7250 switcher are married to the BVE-9100 (with its ability to store switcher setups in the EDL), effect recall achieves yet another level of convenience and precision.

In the time it used to take to manually re-patch a switcher’s input configuration, on the DVS-7250 you can recall a snapshot that re-maps crosspoints, sets up the M/Es and initiates a transition — all with one button — making complex tasks simple.

SONY

Switchable System Standard

In addition to feature flexibility, the DVS-7250 also provides standard and format flexibility, as follows:

• When configured for component digital operation (4:2:2), you can

operate in the 525 or 625 line standard. The appropriate system reference is required.

• When configured for composite digital operation (4fsc), you can

operate in the 525 line standard.

• You can switch aspect ratios between 4:3 and 16:9.

Achieving this level of flexibility is equally easy — all standard and format switching is performed on the integral display screen.

Redundant Power Supplies

Power supplies just sit there and work — no moving parts, no trouble ever, and no need for a backup, right? Hindsight is wonderful, but not when the feed to Telco is black! A little redundancy goes a long way.

To this end, Sony offers optional redundant power supplies for both the switcher processor unit and the control panel. When a power supply problem is detected by the system’s diagnostics, an operator warning appears and the automatic back-up system switches power supplies — with no signal interruption or loss of output.

Power Tools

The DVS-7250 offers superb features, and a little peace-of-mind, too.

This section outlines the features that operators value the most on the DVS-7250. Power tools not only simplify the daily job, but they add to that all-important category of creativity — the area in which a switcher’s artistic and aesthetic capabilities are greater than the sum of its parts.

Timeline Effects

The only thing better than creating a beautiful switcher event — is creating a series of events along a timeline, and editing each event with exacting precision. The

DVS-7250’s timeline feature allows you to create and run switcher timelines for each M/E — plus the DSK — plus user functions such as auxiliary bus control.

In much the same way that you program effects on the DME, switcher timeline effects give you control over the path of wipe pattern position (including spline), the duration of individual events (or “keyframes”), and the relative timing between the various M/E and DSK timelines.

Up to 99 key frame registers are available. The feature allows you to copy, modify, and delete events, save and recall timelines, and preview the completed effects (individually or in combination) on the switcher’s display panel. With timeline control, complex sequences that could not be performed live (nor repeated accurately) can now be programmed, edited and used in a production with ease.

Integrated DME Control

Console space is definitely at a premium in modern control rooms. With each new device taking up space, it seems that there’s barely enough room for the director’s script, let alone a DME control panel. The DVS-7250 reverses this trend with the addition of two optional switcher panels: the BKDS-7030 Key Frame Control Panel and the BKDS-7031 DME Control Panel.

These switcher “insert” panels completely replace the DME’s own control panel. Together, they eliminate unnecessary console footprints, and provide an economical and highly convenient method of effects creation and control. In addition, the switcher’s floppy drive can store DME setups, snapshots, and effects files — as well as switcher data. (Tell the director there’s finally enough room for the script!)

In addition to Sony DME products, a wide variety of digital effects devices from other manufacturers such as Scitex DV (Abekas) and Tektronix-GVG can be controlled directly from the DVS-7250 control panel. This interface utilizes a widely adopted industry standard protocol (Grass Valley Peripheral II), and requires the BKDS-7001 control port expansion for the switcher’s control panel.

Key Modifiers

A keyer that simply keys isn’t good enough! When the client says “show me what you can do with this key,” the technical director needs a creative toolbox from which to offer as many visual options as possible — far beyond basic borders and shadows.

To address this requirement, the DVS-7250 provides extensive key modifiers:

• Each keyer can access the M/E’s wipe pattern generator, and a

separate internal pattern generator for mask.

• Each keyer has an optional dual matte generator for border fill. This

dual matte generator in turn has its own pattern generator.

• With the optional Key Border Generator installed, Border, Drop

Border, Soft Edge, Shadow and Drop Shadow capabilities are added to the effect keyer. The option also provides continuous color, position, width, density and softness adjustments. The key border can be filled with the dual matte generator, or a live video source from the integrated M/E bank utility bus.

• Powerful “copy” functions allow you to transfer settings between

keyers and matte generators with ease.

Now, with the DVS-7250, when the client says “nice, but let’s see something else,” the operator will never run out of creative ideas.

Advanced Chroma Keyer — FineChroma



Sony’s FineChroma technology, available with the optional BKDS-2031 and BKDS-2032 boards together, provides an advanced level of chroma key processing typically found in external chroma key devices only.

Each M/E can be equipped with a chroma keyer that delivers full 4:4:4:4 video and key processing, auto and manual modes, color cancellation, spot color correction, shadow and density control, plus a dual clip and gain feature that allows two separate clips in a single image.

You can also generate a dedicated key source for up to two cameras, providing a constant and convenient matte source as required.

Although the feature list is impressive, it’s the visual results that make the difference. Whether you’re keying transparent glass or working with an unevenly lit background, the DVS-7250’s FineChroma technology delivers clear edges and a remarkable degree of visual realism on screen.

Dual Matte Generators with Color Mix Capability

Switchers stopped being just switchers (in the precise definition of the word) many years ago. They’ve evolved into a combination switching device and artist’s palette, with the ability to mix sources, colors, and patterns as required to bring a storyboard or a production to life.

To this creative end, the DVS-7250 has provision for up to eight internal dual color matte generators — for Key-1 edge and Key-2 edge (for each M/E plus DSK), in addition to Wipe border and Color background (for each M/E). Each of these matte generators has color mix and wash capability, its own dedicated pattern generator, and extensive pattern modifiers. Rembrandt would be jealous.

Frame Memory

The highly versatile Frame Memory function provides storage and playback for two individual frames, divided as needed between video only, or video and key signals. A dedicated internal routing system is provided for each frame, independent of Aux bus operation.

Frame memories can be used for the following creative applications:

• Grabbing fields or frames.

• Layering.

• Creating custom masks.

• Storing matte and fill signals.

• Painting from a user-supplied graphics tablet.

• Re-positioning live or frozen images as a snapshot or animated as a

keyframe effect. A mask can also be applied a live image using an internal dedicated wipe generator.

• Storing and manipulating frozen z-axis images (in conjunction with a

DME’s Depth Key processing).

• Keying and mixing between frames, filling with video from an

internal auxiliary bus or matte generator, then routing the results to any desired internal or external switcher destination.

In much the same way that audio boards allow you to create sub-mixes upstream of the main mix, Frame Memories provide video sub-mix functions upstream of the buses, with the resulting capability — and creativity.

Auxiliary Buses

There’s nothing special about Aux buses, right? Not true with the DVS-7250! Fourteen auxiliary buses are available, with the standard set of primary and M/E crosspoints as you might expect. Using a simple assignment menu, you can place the Frame Memories, Key mattes and fills, and even the clean chroma composited image on the Aux buses.

In fact, every signal that enters the switcher or is internally generated — can be placed on an Aux bus.

The DVS-7250’s Aux bus feature is simple and logical. You can sometimes predict the signals you’ll need before an edit session or production, but once you’re in the midst of it, there’s a confidence in knowing that everything is accessible via the Aux buses — on demand. Whether you’re routing to DMEs, monitors, recorders or an Edit Preview feed, the DVS-7250 offers a total Aux bus delegation package.

Processed Key

The DVS-7250’s Processed Key function is an “effects pathway” that solves the problem of routing signals to and from a DME digital effects system or color corrector, without complex patching. You can compose a chroma key for example, clip and adjust it, route it to the DME for manipulation, and then re-enter it in the same DVS-7250 keyer — with the simple press of a button.

Whether you’re flying logos or re-sizing graphics, the Processed Key approach clearly illustrates the benefits of Sony’s system integration concept. Best of all, the feature works with most other major manufacturer’s DVEs that are equipped with a key channel.

DME-LINK

For live field production and studio production, the DVS-7250’s DME-LINK feature controls up to four Sony Digital Multi Effect systems through the switcher’s control panel. Operators can run specified DME-3000 and DME-7000 effects by the switcher’s fader or transition button — just like wipes and dissolves.

In post, it’s easy — the BVE-9100 editing system sends out serial commands to initiate DME effects. But in live production, you simply don’t have enough hands to trigger all the necessary devices.

With DME-LINK in the path, however, running the DME timeline is easy, and the switcher’s internal transition rate overrides the rate programmed locally on the DME. Over 30 basic effects are available for single and multi-channel DME systems, and on the DME-7000 specifically, up to 12 user-defined digital effects can be used.

DME-LINK once again underscores the DVS-7250’s benchmark principle — making complex tasks simple.

Bus Link Mode

The Bus Link Mode allows you to establish a relationship between the crosspoints of different switcher buses. The mode has valuable applications in both live and post production situations:

• With a link established in a live broadcast, for example, selecting

camera one on M/E 2 could automatically select camera one on an Aux bus. Offsets can also be established through the use of up to five “link relationship tables” — allowing you to select the same source or a different source on another bus, as required.

• In post production, for example, the Bus Link Mode would allow you

to automatically select M/E 2 key matte on Aux 13, each time M/E 2 is used as the program output source.

GPI Link Mode

The GPI Link Mode allows you to establish a relationship between switcher crosspoints and the switcher’s GPI output ports. A variable timing relationship can be established between the crosspoint selection and GPI outputs. For a virtual studio application, for example, selecting a camera (on a switcher bus) would trigger a GPI pulse that in turn switches computer-generated virtual backgrounds. This action also delays the actual video switch by a certain number of fields — allowing the background and foreground to switch in sync.

In operation, the GPI Link can be advanced or delayed from the initial “press” of the switcher crosspoint.
