Abstract
Official abstract text for this publication.
Systems and methods for analyzing the performance of a digital network include capturing a stream of digital data, e.g., interne protocol (IP) packets, that represent streaming video, identifying which of the IP packets include bit errors, determining to which of a plurality of pixels the IP packets including bit errors belong and identifying such pixels as corrupted pixels, and illuminating only the corrupted pixels on a display of a tool. Corrupted pixels in different time blocks can be displayed with different colors to gain a better appreciation of the bit error rate over time.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for analyzing a data stream representing video, the method comprising: capturing a transmitted data stream, being transmitted on a network, the data stream containing data representing streaming video; analyzing the captured data stream, in an analysis step, prior to a decoding step in which the data stream is decoded for display as video; identifying corrupted pixels in the analysis step, represented by digital data in the data stream; and il…
