| Mounting | |||
| Your choices are... | |||
| Desktop / Stand-alone | The video multiplexer design is benchtop or floor-standing with full casing or cabinet and integral interface. | ||
| Panel / Chassis Mount | This type of video multiplexer is designed to be bolted onto a wall, or into a cabinet or enclosure. | ||
| Rack Mount | The video multiplexer is rack-mounted, such as in a standard 19" rack. | ||
| DIN Rail | The video multiplexer is designed with features for mounting on a standard DIN rail. | ||

| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Image Type | |||
| Your choices are... | |||
| Monochrome | Images are presented in black, white, and grayscale. | ||
| Color | Images appear in a range of colors generated with varying combinations of different discrete colors. One common technique is sensing the red, green, and blue (RGB) components and combining them to create a wide spectrum of colors. | ||

Video Inputs

|
|
| ||
| Standard(s) | |||
| Your choices are... | |||
| NTSC | The National Television System Committee (NTSC) 525-line color-television standard used in North America and Japan. Approximately 480 lines hold image information and the remaining lines contain synchronization, time delay, and other encoded information such as closed caption text. The standard frame rate is 30 frames per second. | ||
| 3.58/4.43 NTSC | This input is a version of the NTSC standard. | ||
| PAL | Phase alternate line, the European 625-line, 25-frame per second color-television standard. This modification of the NTSC system is used with the CCIR video norm. The phase of the color carrier is shifted 180° every image line, making the PAL system not as sensitive to color signal phase distortion. It provides somewhat lower vertical resolution than the NTSC system and requires complex processing equipment. | ||
| SECAM | SEquential Color And Memory, translated from the French SEquential couleur aver memoire (SECAM) is a composite color transmission system where color difference signals are transmitted on two separate lines. Memory is required to obtain both color difference signals for color decoding. This system is used in France and many east European, African, and Asian countries. | ||
| RS 170 | RS 170 is the standard black and white video format used in the United States (525 lines, 30 frames per second). It was originally defined by the Electronic Industry Association (EIA) standards organization for use in North America, Japan, and select other parts of the world. The EIA standard defines only the monochrome picture component, but is mainly used with NTSC or PAL color encoding standards. | ||
| RS 330 | RS 330 is a standard recommended by EIA for signals generated by closed-circuit TV cameras scanned at 525 lines, 60 frames per second, and interlaced 2:1. The standard is similar to RS 170, but H-sync pulses are absent during V-sync. Equalizing pulses are not required and may be added optionally during the V-blanking interval. This standard is also used for color television station electrical signals. | ||
| CCIR | Comité Consultatif International des Radio Communications (CCIR), or International Radio Consultative Committee is an international committee that sets and governs video signal standards. It merged with the ITU and became the ITU-R radio communications division. | ||
| HDTV | High definition is a digital video image having at least two times the resolution of standard NTSC or PAL video. The HDTV aspect ratio is 16:9. (Analog TV has a ratio of 4:3.) The FCC is close to establishing a broadcast standard for HDTV. The SMPTE has proposed a high-definition television production standard consisting of 1125 lines, 2:1 interlace, 60 Hz field (30 fps), a 16:9 aspect ratio and 30 MHz RGB and luminance bandwidth. | ||
| Other | Other unlisted video format. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Format(s) | |||
| Your choices are... | |||
| RGB | RGB video output is where red, green, and blue image components are transmitted as separate signals over three separate wires, allowing for full bandwidth for each component. Different synchronization methods are available for RGB. | ||
| Y PbPr | Component video format in which three signals Y, R-Y, and B-Y, are transmitted via separate cables. | ||
| Y/C (S-Video) | S-Video or Y/C outputs contain two separate signals, luminance (Y) and color (C) transmitted on two separate cables. The C color component is modulated on the same 3.58 MHz subcarrier as it would be for an NTSC output, but the bandwidth is not limited as it must be for composite output. | ||
| Composite | Composite output format contains the red, green and blue components of the color (C) encoded or compressed, then superimposed on the luminance (Y) on a single signal. The RGB signals are decoded and reconstructed for image display, but the bandwidth limiting of the signal compression limits the subsequent color faithfulness. | ||
| DVI | Digital visual interface (DVI) is a digital interface standard created by the Digital Display Working Group (DDWG) to convert analog signals into digital signals to accommodate both analog and digital monitors. | ||
| SDI | Serial digital interface (SDI) accepts standard digital input. | ||
| Other | Other unlisted color output format. | ||
