41. Perhaps more interesting is the Packet
Analyzer tab, showing a graph that relates
the data rate with time.

plete PMT tree with all relevant information.

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