Video Systems

Definition : Systems designed for obtaining images from one point and transferring them to another point. These systems usually consist of a device (e.g., camera) that detects variations in light at the source and converts them into an electronic signal; light sources; a processor that transforms the electronic signal to a useful format for transmission, display, and/or recording; and devices to record and display the images, such as video monitors, tape and optical recorders, and video printers. Many video systems are designed for image processing and display using computerized techniques and devices; other systems are designed for transmission and display of images and sound according to standards identical or similar to those used for television broadcasting (i.e., television systems). Television systems may be used either for transmission through the space or over cables (e.g., closed-circuit television systems). Video systems are used in healthcare facilities to facilitate the performance and keep records of procedures in which endoscopes (e.g., colonoscopes, laparoscopes) or surgical microscopes are used, to allow simultaneous visualization of surgical procedures (e.g., for educational purposes), for observation of fluoroscopic images, and to send images to distant locations for diagnostic and information exchange (e.g., videoconferencing).
