  • Page 5: Introduction

    Introduction The Focus Enhancements TView QuadScan product family is a series of products intended to receive analog television signals in various formats, scale them upwards in resolution and play them back on high-resolution projection devices. Using the QuadScan, users can vastly improve the visual quality of television sources.

  • Page 6: The Quadscan Family

    1.2 The QuadScan Family The QuadScan product family consists of one common technology implemented on a common circuit board. Different packaging is added to the base product to provide specific options. 1.2.1 Desktop or Rackmount Desktop Units are standalone items that accept 13 – 20 VDC power from a UL listed power supply. Users of Desktop QuadScans may choose between American compatible, wall mount transformers, with standard American plug configuration (shipped automatically with QuadScan Desktop orders, SKU# 444-5520), or deskmount universal power supplies (shipped with QuadScan Desktop International orders, SKU#444-5524).

  • Page 16: Quadscan Control Functions

    QuadScan Control Functions All of the powerful features of the QuadScan that can be controlled through by its three methods of control described in section 4: front panel control, RS-232/422 and IR remote control. All methods are interchangeable and simultaneously active (i.

  • Page 17: Output Screen Aspect Ratio

    D-ILA projection system with a display device resolution of 1365 x 1024, aspect ratio of 4:3, a user may optimize his projection room for 16:9 viewing by focusing the projector on a 16:9 screen. This will effectively reduce the resolution of the projection system to 1365 x 768. The pixels outside the 1365 x 768 viewing area are still active (although black) and may be focussed into the floor or the ceiling to achieve the desired maximum viewing area at 16:9.

  • Page 18: Motion Processing

    3.4 Motion Processing 3.4.1 Motion Processing (Multiple) This control determines which type of video motion processing will be applied. The options are: Motion Processing Mode Auto Film Motion Still Film Processing (3:2 pulldown sourced material) is used to compensate for the motion artifacts of video program material from film sources.

  • Page 19: Output Sync Signal Configuration

    3.5.3 Composite Pass Through (Toggle) (Not available from IR remote mouse) This control determines whether the Composite television input on Channel A is routed through to Channel B or not. If the signal is “passed through” Composite television that is input on Channel A will appear as an output on Channel B. If the signal is not passed through, Channel B Composite television will be configured as a second Composite television input.

  • Page 20: Termination

    3.8 Termination 3.8.1 VGA Termination (Toggle) (Not available from IR remote mouse) This control engages or disengages 75 Ohm termination resistors on the RGB lines of the VGA pass through. The default configuration is termination resistors engaged. VGA Termination is indicated by “VGA TERM” (VGA input Terminated) or “VGA UNTERM” (VGA Unterminated) on the QuadScan’s Front Panel Display.

  • Page 21: Input Television Video Functions

    3.10 Input Television Video Functions 3.10.1 Brightness (Range) This control adjusts the Brightness of the selected television source. Brightness is not accessible from the front panel when the selected input source is VGA pass through or AUTO. The default value for Brightness will produce internal digital values in accordance with ITU656 when a 100% amplitude, 100% saturation color bar test pattern is applied to the QuadScan’s composite input.

  • Page 22: Output Window Control

    3.11 Output Window Control 3.11.1 Output Horizontal and Vertical Position (Range) (Not available from IR remote mouse) This control enables the user to position the “Output Window” with respect to the raster scan of the display device. Most display devices have a wide range of capability in mapping the boundary of the raster scan to the boundary of the viewable area.

  • Page 23: Input Aspect Ratio Selection

    3.12.2 Input Horizontal and Vertical Size (Range) This control enables the user to control the size of the “Input Window” with respect to the input television source. The Input Window is a smaller section of the television input that will be used as the scaling source. As the Input Size is adjusted, the QuadScan will zoom the contents of the Input Window to the full screen size as defined by the Output Display Configuration and Output Screen Aspect Ratio.

  • Page 24: Quadscan Control Methods

    QuadScan Control Methods QuadScan models can be controlled in one of 3 different ways: Front Panel, RS-232/422, or InfraRed Remote Control. The following sections detail the use of each of these control mechanisms. In all cases, the state of a particular function of the QuadScan is indicated on the QuadScan’s Front Panel LED readout.

  • Page 25: Locking The Front Panel

    4.1.1 Locking the Front Panel A special combination of buttons (the Locking Sequence) makes it possible to freeze control input such that the QuadScan will not respond to Control Panel or IR remote or RS-232/422 commands until a second special combination of buttons (the Unlocking Sequence) is entered.

  • Page 26: Ir Remote Control

    4.2 IR Remote Control The hand held IR remote control enables the user to access many of the functions of the QuadScan. Since the IR unit is intended to access the most commonly used functions, certain setup functions of the QuadScan may only be accessed via the Front Panel or via RS-232/422.

    4.3 RS-232/422 Control All of the functions detailed in section 3.1 are available from RS-232/422 control. Every QuadScan is operable in both RS-232 and RS-422, but must be correctly set up for each standard. When configured for RS-422, up to 8 QuadScans may be connected in a single RS-422 wired system.

  • Page 30 4.3.2 Connecting the QuadScan to communications devices Slightly different connections schemes are required for RS-232 and RS-422 operation. Figure 5 indicates the recommended connections from a DB-9 connector for RS-232 operation. Depending on the way that the controlling port is programmed, other connections may work as well. The QuadScan has no way of handling the RTS/CTS and DSR/DCD signals.
  • Page 31 4.3.3 Selecting the QuadScan’s address In an RS-422, there may be as many as 8 QuadScans operating within a system. In order to provide a control mechanism to differentiate each QuadScan, the user must program each QuadScan’s address using the Front Panel. Programming the address is a simple procedure.
  • Page 32 In addition to the above commands, two additional commands are provided for control information. Writing Value Byte = 01 to register 18 will cause a Full Reset operation to occur. Writing Value Byte = 01 to register 20 will cause the existing parameter set to be written in to NOVRAM.
  • Page 33 For example, the following byte sequences perform the indicated functions: Input Set to Channel A S-VHS Input Source register Zoom Turned On 16 (decimal) Zoom register Decrement Brightness Brightness register Delay time between each transmitted character of a command must be 10 mS or greater. Each command will not be completed until the Carriage Return is received.
