| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| Analog Video Format: | |||
| Your choices are... | |||
| 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. | ||
| CCIR | CCIR (Comité Consultatif International des Radio Communications, 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. | ||
| 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. | ||
| 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. | ||
| 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 less sensitive to color signal phase distortion. It provides somewhat lower vertical resolution the NTSC system and requires complex processing equipment. | ||
| Other | Other unlisted, specialized, or proprietary configuration. | ||
