), which may
be adjusted from unlimited to 1 Mbps. The selected maximum bit rate is displayed on
the right hand side of the slider bar.

Video Quality slider (see figure 50,

).
4. Set the Transform type (see figure 50,

):
z Graphics is optimized for text and sharp lines, (typically computer input).
z Video is optimized for smooth tone changes (typically video content).
5. The bit rate of the streamed image is monitored at the Streams information area of the
Bandwidth page (see figure 50,
4
). For more information, see Monitoring the bit
rate on page 49.
NOTE: The Streams information area is only populated once a connection is made
to a decoder.
