	Standard(s)
	Your choices are...
	NTSC		The National Television System Committee's (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		A version of the NTSC standard.
	PAL		Phase Alternate Line (PAL), the European 625-line, 25-frame per second color-television standard. A modification of NTSC system used with the CCIR video norm. The phase of the color carrier is 180° shifted every image line, making the PAL system not as sensitive to color signal phase distortion. It provides somewhat lower vertical resolution the NTSC system and requires complex processing equipment.
	SECAM		SEquential Color And Memory (SECAM), translated from the French SEquential Couleur Aver Memoire. SECAM is a composite color transmission system in which two 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.
	RS170		RS170 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 EIA (Electronic Industry Association) standards organization for use in North America, Japan, and a few 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.
	RS330		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 RS170, 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 Communication (CCIR), or International Radio Consultative Committee is an international committee that sets and governs video signal standards. Merged with the ITU and became the ITU-R radio communications division.
	HDTV		High Definition Television (HDTV) 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		A type of component video output in which red, green, and blue (RGB) 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 P_bP_r		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 output contains 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 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.
	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.

	Resolution(s)
	Your choices are...
	640 x 480 (VGA)		Video Graphics Array (VGA) is a PC video display circuit and adapter that support text and graphics. Text is supported at a maximum resolution of 80x25 characters in 16 colors. Graphics are supported at a maximum resolution of 320x200 pixels in 256 colors, or 640x480 pixels in 16 colors.
	800 x 600 (SVGA)		Super Video Graphics Array (SVGA) is a set of graphics standards designed to offer greater resolution than VGA. There are several varieties of SVGA, each providing a different resolution. All SVGA standards support a palette of 16 million colors, but the number of colors that can be displayed simultaneously is limited by the amount of video memory installed in a system. One SVGA system might display only 256 simultaneous colors while another displays the entire palette of 16 million colors. A consortium of monitor and graphics manufacturers called VESA develops the SVGA standards.
	1024 x 768 (XGA)		Extended Graphics Array (XGA) is a high-resolution graphics standard introduced by IBM in 1990. XGA was designed to replace the older 8514/A video standard. It provides the same resolutions (640 by 480 or 1024 by 768 pixels), but supports more simultaneous colors (65 thousand compared to 8514/A's 256 colors). In addition, XGA allows monitors to be non-interlaced.
	1280 x 1024 (SXGA)		Super Extended Graphics Array (SXGA) is a set of graphic standards designed to provide higher resolution than XGA. SXGA provides a resolution of 1280 x 1024 pixels, greater than XGAs 1024 x 768 pixels. Like XGA, SXGA can display more than 16 million colors and can support 65 thousand colors simultaneously.
	1600 x 1200 (UXGA)		Ultra Extended Graphics Array (UXGA) is a set of graphic standards designed to provide higher resolution than either XGA or SXGA. UXGA provides a resolution of 1600 x 1200 pixels. As with XGA and SXGA, UXGA can display more than 16 million colors and can support 65 thousand colors simultaneously.
	Other		Other unlisted, proprietary or specialized display resolution.

	Image Controls
	Your choices are...
	Scaling		Scaling refers to the reduction or enlargement of an image or video sequence by squeezing or stretching the entire image to a smaller or larger image resolution.
	Positioning		The ability to exactly position an image or frame.
	Overlay		An edit in which existing video, audio, or both is positioned on top of other material.
	Genlock		A system whereby the internal sync generator in a device, such as a camera, locks on to and synchronizes itself with an incoming signal.
	Zoom		The enlarging or minimizing of an image on a computer monitor to facilitate ease of viewing and accurate editing.
	Saturation		The strength or purity of a color. Saturation represents the amount of gray in proportion to the hue, measured as a percentage from 0% (gray) to 100% (fully saturated). The color information of a video signal comprises hue (phase angle) and saturation (amplitude).
	Contrast		The range of difference between the lightest and darkest values of a picture, or maximum and minimum brightness values.
	Brightness		The intensity of a color as determined on a scale from black (no brightness) to white (maximum brightness). The combination of brightness, hue, and saturation determines the appearance of the colors of a polychromatic image, whereas the brightness alone determines the appearance of a monochromatic image's color.
	Freeze		Freeze is a technique in which a particular frame of video is held onscreen. Sometimes the audio portion of the scene continues playing.
	Other		Other unlisted or proprietary types of image control.
