Methods and apparatus for error rate estimation

摘要

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).

主权项

1. A method for estimating received error rates, comprising:
receiving a scan line of video data comprising a number of symbols; detecting one or more error symbols; when a first invalid error symbol has been detected within the scan line of video data, incrementing an error count and disabling error detection until a next scan line; and estimating a total number of errors, based on the incremented error count.
