In these calculations, the individual terms are instances in time, not quantitative amounts of time. In other
words, channel change time equals time it takes to leave the first stream plus the time it takes to join the
second stream, measured from the respective IGMP requests.
For reference, the unit indicates the following test results:

6.11.3 Channel Guide Settings
This function allows you to configure the unit for channel guide usage. It is available from multiple menus
associated with active Video QoS testing, but the settings are global to all interfaces. For example, you
can access and configure these settings from the 10/100/1G menu, but all changes will also apply to
video testing on other interfaces, such as the modular MoCA interface. For more information about
channel guides, see About channel guides on page 6-53.

About channel guides
A channel guide provides a shortcut for specifying IP video channels during video testing of multicast
streams. When the unit joins and/or monitors a video stream for testing, it requires the IP address and
port of that stream. If you do not have an active channel guide on the unit, you must enter the address
and port manually. However, if you do have an active channel guide that includes the respective channel,
it allows you to select a simple channel number or a more intuitive channel abbreviation, such as CNN or
HBO. The unit then looks up the address and port in the guide instead of requiring a manual entry. A
