The use of DownScan LT is indicated whenever the source and destination of a video signal are incompatible due to different line rates or other signal attributes, and a standard frame rate video signal (30 or 25 frames/second) is required. Examples include conversion of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape, or disk recorders, or other apparatus requiring a standard frame rate signal.

DownScan LT is a digital image processing system that can convert from high line rate video standard of 1023-1125/60 or 1249/50 to low line rate video standards of 525/30 or 625/25. Housed in a 1 3/4" EIA half-rack mount chassis, DownScan LT operates from 100V to 240V AC power.

The use of SplitScreen is indicated whenever two images are required to be shown together side-by-side in a single image/display, and a high-line rate (e.g., 1049 lines @ 30 frames/sec or 1249 lines @ 25 fps) video signal is required. . . Examples include conversion / combining of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and/or ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape, disk, or other apparatus requiring a high-line rate video signal.

SplitScreen is a digital image processing systems that can display 2 pictures side-by-side on a single video monitor. Additionally, SplitScreen has provisions for video scan rate conversion. SplitScreen accepts two input signals at various scan rates, and it outputs video at high-line rate. Both images share the full video frame by splitting them with a vertical boundary. The position of the boundary can be adjusted right or left (thus adjusting the relative amounts of each image viewed), and each image can be panned horizontally within each split area. The result is two images, each of which is full height but cropped horizontally. The output composite image is compatible with high-resolution monitors capable of displaying high-line rate video which is compatible with EIA standard RS-343A.

The use of MultiPics is indicated whenever multiple images (2, 3, or 4) are required to be shown together in a single image/display, and a high-line rate (e.g., 1049 lines @ 30 frames/sec or 1249 lines @ 25 fps) video signal is required. Examples include conversion/combining of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and/or ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape, disk, or other apparatus requiring a high-line rate video signal.

MultiPics (Multiple Picture Scan Converter) is a digital image processing system that can display 2, 3, or 4 pictures on a single video monitor.

MultiPics provides up to three modes of operation: DuoPics operation (Model ME-977-2), TriPics operation (Model ME-977-3), and QuadPics operation (Model ME-977-4).

The intended use for DownScan 120 is conversion of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on display monitors, optical, tape or disk recorders, or other apparatus requiring a standard frame rate video signal (30 or 25 frames/second). The use of DownScan 120 is indicated whenever the source and destination of a video signal are incompatible due to different line and/or frame rates, and a standard frame rate video signal is required. DownScan 120 is intended for use in patient care areas, but is not intended to have any patient contact.

DownScan 120 is a digital image processing system that can convert from very-high-line rate video standard of 1023-1049/60 or 1249/50 (~64 KHz horizontal frequency, often referred to as "flicker free" or "fast" video) to high-line rate video standards of 1023-1049/30 or 1249/25, or to low-line rate video standards of 525/30 or 625/25. Housed in a 1 3/4" EIA rack mount chassis, DownScan 120 operates from 100V to 240V AC power. DownScan 120 consists of an enclosed sheet metal chassis housing one main printed wiring assembly, one secondary printed wiring assembly, and the power supply (100-240 VAC input and ±15 VDC, ±5 VDC outputs). DownScan 120 uses standard SSI/MSI/LSI semiconductor technology. DownScan 120 utilizes eight basic electronic circuits on the primary printed wiring assembly. They are: input analog video conditioning circuit, analog-to-digital conversion circuit, memory circuits, various control circuits, digital-to-analog conversion circuit, two clock circuits, and output analog video conditioning circuit. All of the processing is done in the digital domain. The analog-to-digital converter changes the analog video to an 8-bit digital bus. That digital bus is sent to the memories for processing. Memory control circuits manage the locations and the timing of how the video is being stored in the memories and then read from memory before sending the resultant signal to the 8-bit digital-to-analog circuit. The write clock generator provides clock timing for analog-to-digital conversion, the memories and the memory control circuits. The read clock generator provides read clock timing for the memories and the digital-to-analog circuits.

The intended use for UpScan 120 is conversion of X-ray (stationary, C-arm, angiography, etc.), nuclear medicine, magnetic resonance, and ultrasound images either directly from their source, or from an intermediate storage device (like a video tape or video disk), for use on high resolution display monitors or other apparatus requiring a very-high-line rate video signal (e.g., 1023-1049 lines @ 60 frames/second, or 1249 lines @ 50 frames/second). The use of UpScan 120 is indicated whenever the source and destination of a video signal are incompatible due to different line and/or frame rates, and a very-high-line rate video signal is required. UpScan 120 is intended for use in patient care areas, but is not intended to have any patient contact.

UpScan 120 is a digital image processing system that can convert from low-line rate video standard of 525/30 (or 625/25) or high-line rate video standard of 1023-1049/30 (or 1249/25), to very-high-line rate video standard of 1023-1049/60 (or 1249/50), often referred to as "flicker free" or "fast" video. Additionally, UpScan 120 can provide a (pre-)fixed amount of vertical edge enhancement to the output video signal, and can also invert the video image (black ⇌ white). Housed in a 1 ¾" EIA rack mount chassis, UpScan 120 operates from 100V to 240V AC power. UpScan 120 consists of an enclosed sheet metal chassis housing one main printed wiring assembly, one secondary printed wiring assembly, and the power supply (100-240 VAC input and ±15 VDC, ±5 VDC outputs). UpScan 120 uses standard SSI/MSI/LSI semiconductor technology. UpScan 120 utilizes nine basic electronic circuits on the primary printed wiring assembly. They are: input analog video conditioning circuit, analogto-digital conversion circuit, memory circuits, digital video line interpolator circuits, digital processing circuits, various control circuits, digital-toanalog conversion circuit, two clock circuits, and output analog video conditioning circuit. All of the processing is done in the digital domain. The analog-to-digital converter changes the analog video to an 8-bit digital bus. That digital bus is sent to the memories for processing. Memory control circuits manage the locations and the timing of how the video is being stored in the memories. The line interpolator circuits interpolate the output digital bus from the memories, and the digital processing circuits add desired vertical edge enhancement and/or video inversion before sending the resultant signal to the 8-bit digital-to-analog circuit. The write clock generator provides clock timing for analog-to-digital conversion, the memories and the memory control circuits. The read clock generator provides read clock timing for the memories, the line interpolator and the digital-to-analog circuits. UpScan 120 and one of the predicate devices (Merlin UniScan) are realtime video processing systems which are designed to convert monochrome video images from one video format to another. The only differences are a higher clock frequency and the ability to output video at twice the standard frame rate. UpScan 120 and the other predicate device (Merlin CrisPics) are real-time video processing systems designed to provide edge enhancement and/or video inversion for monochrome video signals. UpScan 120 and all of the predicate devices utilize similar technology to perform their functions. These systems all convert the incoming analog video signal to digital form using 8-bit analog-to-digital converters, process the signals in the digital domain, and convert back to analog video using 8bit digital-to-analog converters for the output.
