Controlled Load (C)—Traffic will receive nonguaranteed priority treatment similar to a network with no load.

Qualitative (Q)—Traffic will receive nonguaranteed priority treatment.

Refer to the Cisco IP/TV Content Manager User Guide for information on how to enable and configure QoS parameters.

Reception Quality

Two reception quality indicators, located on the Reception toolbar in the viewer window, indicate reception quality levels. (See Table 4-4.)

Description

 

Shows the level of reception quality on your computer as detected

 

by IP/TV Viewer.

Shows the level of reception quality as detected by other workstations on the network that are viewing the same program. This receptor applies only to scheduled programs and not to on-demand programs.

These indicators change colors to reflect varying reception quality. (See

Table 4-5.)
