The main difference between the various models is the output signal scan rate (doubled / undoubled), the size of the case (1/2 rack or full rack), and the type of connectors used for audio and video connections. In the IN1510 and IN1710 decoders, the Composite Video or S-Video input signals are decoded and output as an RGB interlaced video signal at the same frequency as the original signal. The IN1222 and IN1422 scan doublers first decode the input signal (using the same circuitry as the IN1510 / IN1710) and then double the number of scan lines. The IN1222 / IN1422 output a non- interlaced RGB video signal at twice the horizontal scan rate of the original input signal. Functions which apply to the IN1222 / IN1422 but not the IN1510 / IN1710 will be designated in this manual as IN1222 / IN1422 only. The chart below indicates the major differences between the four models.

The primary benefit of scan doubling is the elimination of visible scan lines, resulting in a solid, film-like image. Additional benefits include a marked reduction of line flicker and cross- color interference. ¦ Two Doubling Modes : Line Doubling - Best for motion video sources, minimizes motion artifacts. Frame Mode - Best for still video sources, maximizes image detail. ¦ 4 x 1 Video/Audio Switching: Three inputs for Composite Video / S-Video with stereo audio One RGB input with stereo audio (passive, no decoding or doubling) ¦ RS-232 control of all parameters ¦ Front panel controls to adjust signal parameters - Hue, Color, Sharpness/Contrast, and Volume. ¦ Gamma Correction - 7 different gamma curves allow compensation for display device characteristics ¦ Input Memories - users may store a unique set of signal parameter adjustments for each input (Hue / Color / Contrast / Gamma / Composite Video / S-Video / Volume / Doubled / Undoubled, etc.). Settings are automatically recalled each time an input is selected ¦ Selectable output sync configuration: RsGsBs, RGBS, or RGBH&V ¦ Horizontal position control (available through RS-232 control in non-doubled mode only) ¦ Disable scan doubling allows the units to function as decoders only (IN1222/IN1422 only). ¦ Digital freeze frame provides rock-solid still video images (IN1222/IN1422 only). ©1994 -INLINE, INC. IN1222 / IN1422 / IN1510 / IN1710 OPERATIONS MANUAL -REV. 2 12/04/99 INPUT COMPATIBILITY The IN1222/1422 and IN1510/1710 will operate with NTSC, PAL, or SECAM input signals in composite video or S-video format. For a complete listing of compatible input video standards see page 20. All video and audio input jacks are shown in the diagrams on pages 3, 6 & 7. Composite Video / S-Video Signals The IN1222 and IN1510 feature three 4-pin mini-DIN connectors for direct connection of S- Video signals. Composite video signals may be connected to Inputs 1, 2 and 3 by using an IN9091 adapter (included), which features a female RCA connector for composite video input. The IN1422 and IN1710 feature three female BNC connectors for composite video input and three mini-DIN connectors for S-video input, allowing up to six video sources to be connected simultaneously. RGB Video Signals Input #4 on all units is a passive RGB input which will accept virtually any video signal in any format (the unit will pass up to five signal components). RGB signals sent into Input 4 are not decoded, doubled, or altered in any way and simply pass through the unit. This passive input is typically used to hook up a computer to the doubler/decoder, allowing users to switch between the computer video input and various composite video or S-video inputs. The IN1222/IN1510 provide a female 15-pin HD connector for the RGB input. The IN1422/IN1710 provide a female 15-pin HD connector and 5 BNC connectors for the RGB input. These two connectors are wired in parallel and only one of them should be used at any time. Stereo Audio Signals All units include a stereo audio input jack for each of the four inputs. The units feature audio-followvideo switching meaning that any time an input is selected, one video signal and its companion audio stereo pair are simultaneously routed through the doubler/decoder. The audio inputs are unbalanced and are intended for line level audio signals. The IN1222/IN1510 feature four 3.5 mm ...
