41. Perhaps more interesting is the Packet<br />
Analyzer tab, showing a graph that relates<br />
the data rate with time.<br />
42. The PMT Analyzer tab shows the complete<br />
PMT tree with all relevant information.<br />

the program specific information.<br />

Testing latency: the computer<br />
monitor in the back shows the original<br />
image, the DEVISER S7000 analyzer<br />
on the left shows the compressed<br />
video received through the IP stream<br />
and the meter on the right shows the<br />
same stream received through the<br />
ASI port. Latency on ASI is extremely<br />
low and the higher latency of the IP<br />
stream is not the CW-4412’s fault: it is<br />
actually the time it takes transcoding<br />
the stream back and forth to IP. Even<br />
the ASI stream takes a short while<br />
to be decompressed and rendered<br />
on screen. I was impressed with the<br />
fantastic low latency of the CW-4412.<br />
