FOR-A’s HVS-4000 is a 2 M/E, 2.5 M/E, or 3 M/E multi format video switcher. It has a wide range of features, including HD/SD mixed input, 3 Gbps support, 2.5D and 3D DVE, multiviewer, up/down converter, external device control, macro function and video file support. It also comes with a number of interfaces and functions for connecting to external devices, making it extremely useful as the core device in your video production system.


2 M/E, 2.5 M/E, and 3 M/E models

The HVS-4000 Series offer you a choice of three models, a 2 M/E, 2.5 M/E, or 3 M/E model. The main unit and options are the same, so you can upgrade to 3 M/E even after purchasing a 2 M/E model. The main unit has a redundant power source, DVE board and a number of options for adding functions, all in a main unit. Helping to reduce system peripherals and save you space.
*The number of rows of the control panel buttons and optional devices that can be added are varied, depending on the specification requirements.

HVS-4000HS Main Unit

Five types of Control Panel

The control panels available for the HVS-4000HS include three types of 2 lines models (2 M/E) and two types of 3 lines models (2.5 M/E or 3 M/E).

2 Lines Model (2 M/E)

    A control panel with the traditional easy operation of the HANABI Series, great for simple, direct operations
  • HVS-2163OU: 2 Lines model, 16-button type
  • HVS-2243OU: 2 Lines model, 24-button type
  • HVS-2244OU: 2 Lines Model, 24-button type




3 Lines Model (2.5 M/E or 3 M/E)

    A control panel that puts the emphasis on direct access to preset content, including a macro bus and event recall button for each M/E
  • HVS-3244OU: 3 Lines model, 24-button type
  • HVS-3324OU: 3 Lines model, 32-button type



Supports HD/SD Mixed Input

With its simple panel operation, the HVS-4000 lets you switch between HD and SD signals and the various HD formats. With the optional up/down converter card installed, the system can support mixed input from HD and SD devices. With the switcher alone, it is possible to perform mixed processing without concern for the differences between HD and SD signals.

Supported formats:
HD-SDI: 1080/59.94i, 1080/50i, 1080/30PsF, 1080/29.97PsF, 1080/25PsF, 1080/24PsF, 1080/23.98PsF, 720/59.94p, 720/50p
SD-SDI: 525/60, 625/50

Supports 3 Gbps Signal (option)

In addition to HD and SD signals, support for the next-generation signal standard 3 Gbps is an available option (HVS-4000HSA only).
*HVS-4EX option is not supported 3 Gbps.

Supported formats:
3G-SDI: 1080/59.94p, 1080/50p

Maximum 48 Inputs and 28 Outputs

HD/SD-SDI 16 inputs, 16 outputs come standard. And can be expanded up to 48 inputs (in units of 16) and 28 outputs (adding 12). A side panel and safety marker can be added to the AUX output.
The HVS-4000 also comes with two utility bus channels per M/E. These channels can be used for keyer external mask, wipe border, a background needed for M/E bus P-in-P, side panel, and local still.

Up/Down Converter

The HVS-4000 allows the option of adding an up/down converter*. With a frame synchronizer, asynchronous video can be input as is (up to four channels with this option).
*No frame rate converter function provided.

Up to 18 Keyers

The HVS-4000 comes standard with 4 keyers for each M/E. Eight keyers are standard on the 2 M/E model, 11 keyers are standard on the 2.5 M/E model and 12 keyers are standard on the 3 M/E model (P/P line has 3 keyers). Two keyers can optionally be added to each M/E. This lets you expand to up to 12 keyers on the 2 M/E model, 15 keyers on the 2.5 M/E model and 18 keyers on the 3 M/E model.

AUX Bus Dedicated DSK

As an additional option, you can add two dedicated DSK to an AUX bus. Allowing you to do superimposing on each AUX output.

Combiner Function (to be supported in the future)

HVS-4000 can be added with the independent combiner function besides the M/E function. For example, the combiner function can be used by installing to the HVS-4000 in the stage prior to the M/E process and adding DVE to the input signals in order to provide multiple P-in-P video via a single channel (pre-combiner function). It can also be used by installing to the HVS-4000 in the stage subsequent to the M/E process and utilizing it for CG composition (L-shaped left side and bottom of the screen).

Maximum 12-channel Still Stores

Six still stores (Global Still) that can be selected for all buses come standard. The switcher can be expanded up to eight still stores. Furthermore, four more dedicated still stores (Local Still) can be added in each M/E, bringing the number of still stores to a total of 12. A logo animation function, is also provided. A motion logo which loops a succession of still images.


A 4/10/16-way multi-viewer comes standard. Two multi-viewer modes are available: one multi-viewer channel for the 10- or 16-way mode and two multi-viewer channels for quad mode. A multi-viewer function with one channel for 10-way mode or a function with two channels for quad mode can be added as an option.


2.5D DVEs and 3D DVEs can be added simultaneously. Up to six channels can be added to the 2.5D DVE, whereas up to eight channels (in 2-channel units) can be added to the 3D DVE. A total of up to 14 channels of DVEs can be added. All DVEs can process V+K on one channel. The number of channels does not decrease even when the flying key effect is used. 3D DVEs use the same architecture as in the HVS-5000 series. This allows DVE effects with high image quality and high functionality.


HVS-4000 has adopted a conventional built-in DVE system (LINE DVE) for four channels and external DVE system for the remaining four channels. This makes it possible to select advanced 3D DVE video as a single body of material from multiple buses. The use of DVE widens the scope of creative video broadcasting, for example, using 2.5D DVE for Picture in Picture (P-in-P), 3D DVE for P-in-P and transitions, and 3D DVE for video material production added with digital video effects.

Color Corrector

A full-featured, optional two-channel color corrector can be added for inputs. This allows color correction for any two input channels. The color corrector option can also be added for each bus. Because the color corrector option for four channels per single output card can be added for the AUX bus, this feature is useful for suppressing illegal signal outputs and color adjustment for on-set monitors.

Macro Function

The HVS-4000 comes with macro function to record and play back complex operating procedures with just one button. This lets you easily register a series of operations and then perform complicated operations with one push of a button. For example, you could send a play command to a VTR, then switch to the VTR channel after waiting a set amount of time before footage playback begins.

Sequence Function

Allows you to register changes in parameters as a sequence. By using the optional GUI software, a timeline can be displayed, making it easy to make corrections or changes. Up to 20 sequences can be registered.

Event Memory

The HVS-4000 comes with event memory capable of registering all types of parameter settings. Up to 200 events can be registered.

Clip drive unit

An optional motion picture playback unit can be connected. With one unit, it is possible to record and play back up to one hour of HD full motion video (30 minutes in the case of V+K), which can be used for all types of animation, including CG wipes and opening CG. When an optional clip drive is connected, the clip function using the still store video path can be added. To achieve CG wipes with ordinary video switchers, it is typical to make the connection settings to an external device by using a switcher’s timeline function to put together the key frames. But with FOR-A’s HVS-4000 HANABI Series, all you need to do is make the setting as a wipe function to achieve a CG wipe that connects to auto-transition. This unit, which we offer as an external add-on option, supports video signal input and file transfer (MXF files) from a PC by Ethernet.


External Device Control

Enables integrated control of various external devices such as routing switcher, VTR, DDR, clip server and multi-viewer. Video names on the switcher control panel can be changed in accordance with crosspoint switches on the router. The switcher tally information can be also sent to other devices such as a multiviewer through the router with video names.
