Abstract: Digital video transmission systems consisting of a video encoder, a digital transmission method (e.g., Internet Protocol – IP), and a video decoder can produce pauses in the video presentation that result from dropped or repeated video frames. For example, a common response of a video decoder to dropped IP packets is to momentarily freeze the video by repeating the last good video frame. This document presents a No Reference (NR) metric and a Reduced Reference (RR) metric for detecting these dropped video frames. These metrics may have application for in-service video quality monitoring.
Keywords: video; metrics; dropped; frames; no reference (NR); Reduced Reference (RR)
