+Arbitrary CEC bus traffic
+-------------------------------------------------------------------------------
+
+These captures contain the typical command exchange between 2 CEC capable
+devices. In this case a Sony TV and 2 different amplifiers were used.
+
+The captures were taken connecting the TV and one of the amplifiers to later on
+switch the TV off and back on while dumping traffic on the CEC bus.
+
+The power OFF and power ON sequence can be seen in the captures with the 
+2 different amplifiers (Yamaha / Denon).
+
+Another spare capture was performed connecting one amplifier to the ARC input
+of the TV.
+
+
+Logic analyzer setup
+--------------------
+
+The captures were taken using a Saleae Logic (fx2lafw), sampling at a rate of 
+1MHz. Channel 3 of the analyzer is used for the CEC bus traffic.
