| Description | : The loss or excessive delay of video data in networks causes glitching in the display of video. In this paper, we consider some glitch statistics (i.e., glitch rate, average spatial extent, and duration) to evaluate network performance when carrying video traffic. We present some numerical results for ATM and 100Base-T Ethernet networks, obtained by simulating these networks using real video traces for various contents and encoding schemes. 1 Introduction In the context of networked video, glitching is the word used to refer to the effect seen by the viewer in the display of video due to the unavailability of video data at the decoder when needed (i.e., when there is a discontinuity in the video stream). The unavailability of video data may be due to two reasons: (i) the data may have been lost or not delivered in time; (ii) the data may have been delivered in time, but it may depend on other parts of data that are not available. Such unavailability of video data results in portion... |
