other would be the even numbered lines. All the odd lines, then
all the even lines, are refreshed 50 times per second, alternating
between the two. This means the whole video frame refreshes 25
times per second. This is fine for smaller screens but can result
in flickering on larger screens.
Progressive scanning
(720p & 576p) refreshes the whole video
frame (all even and odd horizontal lines) 50 times per second.
This eliminates flicker but requires the TV to process more
information since twice as many frames are displayed each
second.
Native, Hybrid, and Fixed Formats
The TiVo
®
Media Device offers three types of form ts that control
how broadcast signals are converted—if at all—for display on your
TV.
If your TV supports all formats, choose the
Native
option. If your
TV supports a limited number of formats, choose the
Fixed
or
Hybrid
format that best matches your TV’s capabilities:
Native
. When you use the native format, the media device does
not convert broadcast signals. It displays the signals in whatever
format they were originally broadcast. Native is recommended if
your TV supports all four video formats (1080i, 720p, 576p, and
576i).
Hybrid.
When you use a hybrid format, the media device
converts standard broadcast signals to 576p. It converts HD
broadcasts to the HD format you choose. Hybrid is
recommended if your TV supports either 720p or 1080i, but not
both.
Fixed.
When you use a fixed format, the media device converts
signals broadcast in other formats to the fixed format you
choose, and video is always displayed in this format. Choose the
fixed format that matches your TV’s highest resolution. Using a
fixed format eliminates any screen flicker associated with
switching formats automatically.
See “Video Settings” in Chapter 5 for more.
Choose What Looks Best to You
Choose the video output format you want the media device to use
based on the formats your TV can display. Check your TV’s
owner’s manual to be sure of your TV’s capabilities. Then go to the
TiVo Central
™ screen and select Messages & Settings, then
Settings, then Video, then Video Output Format.
You should feel free to experiment with all the different video
formats that your TV and the TiVo Media Device support. You may
find that some formats are better suited to certain programs than
others.
