Abstract
Presented herein are system(s), method(s), and apparatus f or detecting and recovering from false synchronization. When incorrect checksums are encountered, false synchronization and general noisy considerations are distinguished as causes of the incorrect checksums by examining the header data. For example, in one embodiment, a count can be kept and false synchronization and noisy conditions can be distinguished based on the number of detected null packets. In another embodiment, a count of detected PAT packets can be kept, and false synchronization and noisy conditions can be distinguished based on the number of detected PAT packets. In another embodiment, continuity information can be monitored and false synchronization and noisy conditions can be distinguished based on the continuity of the data packets.
