1 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. The QuadScan is a Video Scaler, which means that the output resolution can be controlled or “scaled” to fit the resolution of the output device.
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.
In addition to the above components, the user may order other cables, components and spare parts for special applications. A list of these items and their part numbers appears in section 1.4. 1.2.

3 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. e. a front panel button push can be followed by an IR remote control command). Not all controllable items are accessible by the IR remote mouse.
3.2 3.2.1 Output Screen Aspect Ratio Output Screen Aspect Ratio (Multiple) (Not Available from IR remote mouse) The Output Screen Aspect Ratio control interacts with the Output Display Device Configuration and Input Aspect Ratio Selection to position the scaled and process image in the best screen position for a given combination. It is important to remember that the Screen aspect ratio is different from the Display Device aspect ratio.
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 Front Panel Designation Auto Auto Film Film Motion Motion Still Still Film Processing (3:2 pulldown sourced material) is used to compensate for the motion artifacts of video program material from film sources. Motion Processing is used to compensate for the motion artifacts of motion video program material from 60 Hz. (50 Hz.
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. The default is Channel B configured as an input.
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. . 3.8.
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.
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. This control is provided to enable additional control in the event that the user’s display device does not provide sufficient range.
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.
4 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. On power-up, the LED display indicates “QUADSCAN”. 4.
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. The locking sequence consists of: Advance the panel menu to “QuadScan”, first press the “down” key and while still pressing the “down” key, press the “-“ key.
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. This prevents the accidental use of some controls (i. e. switching to an unsupported output resolution) and keeps the interface simple. The Remote Control interface is indicated in Figure 3.

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. The QuadScans will react to controls that are delivered to a unique address that is programmed into each QuadScan via the Front Panel control.

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. Figure 6 indicates the recommended connections from a DB-9 connector for RS-422 operation.
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. Turn the QuadScan on, or cycle the control sequence such that the Power Up Identification is visible (i. e. “QUADSCAN”) on the LED display. Press the Right Arrow Button.
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. The QuadScan will subsequently power up with these saved parameters until the NOVRAM is once again changed by writing a 01 to register 18.
For example, the following byte sequences perform the indicated functions: Input Set to Channel A S-VHS 7 Input Source register 5 5, therefore S-VHS A 13 1 1, therefore On 13 0 Decrement by 1 13 Zoom Turned On 16 (decimal) Zoom register Decrement Brightness 4 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.
