Abstract
Official abstract text for this publication.
Methods and apparatus for estimating received error rates. In one embodiment, the estimation of received error rates is conducted in relation to a bus interface such as a high-speed High-Definition Multimedia Interface (HDMI) interface, and the method utilizes corrupted symbols that violate TMDS symbol rules, the corrupted symbols being easily detected and counted. In one exemplary implementation, a symbol error rate (SER) can be estimated from the number of detected invalid symbols. The SER can be used to diagnose the performance of the HDMI interface, and optionally as a basis for selecting or implementing corrective action(s).
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for estimating a rate of symbol errors, the apparatus comprising: one or more interfaces, the one or more interfaces configured to receive data communication from an upstream device; and at least one controller in operative communication with the one or more interfaces, the at least one controller configured to: detect one or more invalid symbols received over the one or more interfaces based at least in part on a scrambling configuration and…
