48 Input×16 Output Crosspoint IC Eliminates the Need for Multiplexer Amps -
02/20/03 EDN-Design Ideas: Crosspoint switches are ideal for use in video-security
systems, which accept multiple camera inputs while providing playback and multiple
loop-through to multiple monitors. To provide video loop-through or monitor outputs,
se systems often require additional multiplexer amplifiers that can drive standard
video loads.....(design idea added 1/05)
Component Video-to-RGB Converter - This is to convert component video signal (YUV
(YCrCb) into RGB video signal. This will able to attach recent digital video
equipments to old RGB monitors. (added 10/05)
CRT Display Controller - This is an HD6445 based display control interface that
outputs to TV or RGB monitor. It is designed as so to be controlled with many board
microcomputers, so it can easy to control CRT monitor. And its resolution is 256x200
dots, 16 colors. (added 10/05)
General Purpose Display Controller - This is a general purpose display controller
for small microcontrollers. It will be used for various use because it is easy to
change its configuration through using a CPLD. (added 10/05)
NTSC Test Signal Generator - An accurate test signal generator for television
calibration and measurements. (added 10/05)
NTSC-to-VGA Scan Converter - This is a scan converter for NTSC signal from TV,
VCR, LD or DVD to VGA conversion. Your VGA monitor will able to be used for video
monitor. (added 10/05)
NTSC-to-VGA Scan Converter #2 - This is a scan converter for NTSC signal from TV,
VCR, LD or DVD to VGA conversion. Your VGA monitor will able to be used for video
monitor. (added 10/05)
RGB-to-Monochrome Converter - Matches impedance of PC to CCTV monitor. Often you
can get away with running a monochrome monitor on GREEN, but this looks real crappy
when viewing color images. These simple resistor networks allow you to display R+G+B
on a B/W or CCTV monitor without ghosting. Be sure to set your video card for 60Hz
interlaced....(added 2/05)
Superimposer - This is a video superimposer (titler) like above. Its resolution is
512x240 dots, monochrome, so that it can displays Kanji characters. It is designed
using only conventional parts. (added 10/05)
The LM1823 - National Semiconductor Application Note (app note added 2/06)
Video Circuit Clamps Under All Conditions - 04/23/98 EDN-Design Ideas: [Note: File
contains multiple circuits scroll to find this circuit.] Many video-circuit clamps
operate well in the presence of a composite-video signal but cannot achieve a clamp
level with signals other than composite video or in the absence of an input
signal.....(design idea added 11/05)
Video Inverter - This is a simple one-transistor circuit to invert the whole video
signal, including sync pulses. (added 4/02)
Video Line Selector - This is a video line selector to be used to measure video
signal. It triggers oscilloscope at selected line and the oscilloscope displays the
selected line. (added 10/05)
