unreferenced date June 2009 The field rate of an interlaced video image is twice the effective frame rate , since interlacing draws only half of the image the odd or even numbered lines at a time. For example, a field rate of 60 Hertz will correspond to a 30 frames per second moving picture. A field rate can apply to either a video signal, or to a monitor designed to display that signal without conversion. Theoretically, an interlaced signal could have three or more fields per frame, resulting in a field rate that is a 3x or higher multiple of the frame rate. However no such signal is in common use today. Progressive scan monitors do not have a field rate, however they may still display interlaced video by converting each field into a full frame, a process called deinterlacing . In this case, the monitor s frame rate would then likely match the video signal s field rate. physics stub Category Film and video technology ... more details
Merge service level date September 2010 In business, service rate is a performance metric used to measure the customer service in a supply economics supply organization. One example of a service rate measures the number of units filled as a percentage of the total ordered and is known as fill rate. If customer orders total 1000 units, and you can only meet 900 units of that order, your fill rate is 90 . In statistics, notably in queuing theory, service rate denotes the rate at which customers are being served in a system. It is the reciprocal of the service time. For example, a supermarket cash desk with an average service time of 30 seconds per customer would have an average service rate of 2 per minute.
