re sent in moving picture films. A variable number, typically between 8 and 30, are sent in videoconferencing systems, depending on the transmission bandwidth offered. frame buffer Memory used for holding the data for a single and complete frame (or screen) of video. Some systems have enough memory to store multiple screens of data. Frame buffers are evaluated in terms of how many bits are used to represent a pixel. The more bits that are used, the "deeper" the color. The greater the number of buffers used to store captured video frames the higher the possible frame rate. frame dropping The process of dropping video frames to accommodate the transmission speed available. frame grab The ability to capture a video frame and temporarily store it for later manipulation by a graphics input device. frame grabber A PC board used to capture and digitize a single frame of NTSC video and store it on a hard disk. frame rate The number of frames that are sent in a second, and the equivalent of fps. NTSC video has a frame rate of 30 fps. PAL and SECAM send frames at a rate of 25 per second and motion picture (film) images are delivered at a frame rate of 24 per second. frame store A system capable of storing complete frames of video information in digital form. This system is used for television standards conversion, computer applications that incorporate graphics, video walls and various video production and editing systems. freeze frame A single frame from a video segment displayed motionless on a screen. Also, a method of Video Communication: the Whole Picture transmitting video images in which less than one or two frames are sent in any given second. Sometimes known as slow-scan, still video or captured frame video. When freeze frame video is viewed, the viewer sees successive images refreshing a scene but they lack a sense of continuous motion. frequency The number of times that a periodic function or oscillation repeats itself in a specified period of time, usually one second. The unit of measurement of frequency is typ
