Frequently Asked Questions
What is HDTV?
High-definition television is a high-resolution digital 
wide-screen TV format.A high-definition TV signal has 
twice the color resolution and imparts a picture that is 
six times sharper than that provided by a traditional 
analog TV set. HDTV likewise provides enhanced 
audio, such as Dolby Digital.
How is HDTV Different?
The usual National Television Standards Committee 
(NTSC) analog TV screen in the U.S. has 525 scan 
lines, with 480 actually visible. The usual TV has an 
effective picture resolution of about 210,000 pixels. In 
the highest resolution digital TV formats, each picture 
contains about 2 million pixels. This means about 10 
times more picture detail on the HDTV screen!
I keep hearing about 720p and 1080i signal formats – what does Mediacom support?
The formats used in HDTV are:
• 720p - 1280x720 pixels progressive
• 1080i - 1920x1080 pixels interlaced 
The settop will automatically convert all high-definition 
signals to 1080i format regardless of the format of the 
broadcast signal.
4:3, 16:9, wide screen and pan and scan – what 
does it all mean?
4:3 (width: height) is the standard television shape. 
HDTV's have been manufactured in both 4:3 and 16:9 
aspect ratios. 16:9 (width: height) is the traditional 
shape of a HDTV, although some HDTV's have been 
designed with a 4:3 aspect ratio. Wide screen is a term 
used for the 16:9 aspect ratio. Most HDTV sets are 
easy to identify because of their wide screens. These 
screens, which are usually a lot wider than they are 
tall, closely resemble their movie theater counterparts. 
Pan and Scan is a tool that can be deployed to present 
16:9 content onto a 4:3 television (vs. letterboxes).The 
“pan and scan”technique displays only part of the picture at any given time, so that it can fill up the entire 
display screen rather than require sidebars to fit within the 4:3 HDTV display ratio.
What is the difference between “interlaced” and 
“progressive” scan?
"Interlaced" or "progressive" refers to the scanning 
system. In an interlaced format, the screen shows 
every odd line at one scan of the screen, and then follows that up with the even lines in a second scan. 
Since there are 30 frames shown per second, the 
screen shows one half of the frame every sixtieth of a 
second. For smaller screens, this is less noticeable.As 
screens get larger,the problem with interlacing is flicker. Progressive scanning shows the whole picture, 
every line in one showing, every sixtieth of a second. 
This provides for a much smoother picture, but uses 
slightly more bandwidth.
Will I be able to view closed captioning with HD 
Service?
To enable closed captions on the HD settop you must 
access the On Screen Display. Begin by powering ON 
your HDTV and powering OFF the settop box. Press the 
MENU button on either your Mediacom remote or the 
settop box front panel to call up the On Screen Display. 
You may use either the front panel or the remote to 
navigate the display. Arrow down to the Closed 
Caption menu option. Use the right arrow button to 
select the option to Enable closed captions. Press the 
POWER or MENU button to exit the menu and save 
your settings.
I am tuned to a high-definition channel, however 
the picture is not displayed in full screen. What is 
wrong?
Not all programs are in high-definition format and 
therefore programs will not always be full-screen. Not 
every show currently broadcast by a HD station is in 
HD format. You can assume that if you are getting a 
picture on the HD channel, then your equipment is 
functioning properly. You may want to check your HD 
monitor (TV set) settings (consult the HD monitor's 
user manual).
Can I view all my regular TV channels through the 
HDTV connection?
Yes, but you may get what is known as "burn-in" on 
the sides of your TV screen. This could ruin your television, especially if it is a projection-type television. 
Consult your TV’s user manual for information regard- 
ing viewing 4:3 (standard video) programming in its 
native format.
When I tune to a high-definition channel, the picture seems to take a long time to display. Is this 
normal?
Yes, it may take up to 5 seconds for a high-definition 
picture to first display. This occurs because there are 
many more pixels to be created, thus, more time is 
required.
Why is the aspect ratio of different programs 
inconsistent?
The aspect ratio of the content is controlled by the 
service providers (HBO, Showtime etc.). You can go to 
the HBO website at www.hbo.com, the Showtime 
website at www.sho.com, hdtvgalazy.com or 
titantv.com to find out which programming is in 16:9 
HDTV.As time goes on, there will be more and more 
HD in 16:9 aspect ratio. Whether the HD signal is in 4:3 
or 16:9 formats, the picture quality will be better 
(crisper,clearer, etc.) than an analog or a standard digital signal. The reason for this is that there is up to 5 
times the information, or data, for each HD service 
than there is for standard digital, no matter what the 
aspect ratio.

Optimizing Your HDTV Picture
Use the on screen menu to tailor your HD settop box to the 
capabilities of your HDTV.This allows the HD settop box to automatically optimize both Standard and High-Definition video, 
based on your HDTV and personal preferences.
To access the On Screen Menu, power ON your HDTV and 
power OFF the HD settop box. Press the MENU button on either 
your remote control or the HD settop box front panel to call up 
the On Screen Display.* You may use either the HD settop box 
front panel or the remote control to navigate the display:
• The arrow on the left indicates the position of the cursor.
• Press the   and   buttons to select the setting you wish to change.
• Press the   button to select an option for that setting.
• To exit the setting and move to another setting, use the   and   buttons.
• Press the POWER or MENU button to exit the menu and save your settings.
TV TYPE
The first user setting is TV TYPE.Your selection tells the HD settop box what type of TV you have and how 
you prefer to watch widescreen programming. Your choices are 16:9, 4:3 Letterbox, or 4:3 Pan Scan.
• Choose 16:9 if you have a widescreen HDTV.
• Choose 4:3 Letterbox if you have a standard TV and you prefer to watch widescreen 
programming in its original aspect ratio.
• Choose 4:3 Pan Scan if you have a standard screen TV and you prefer that widescreen 
programming is cropped to fill your screen. Think of this last choice as watching a theaterstyle movie that has been reformatted to fit your standard screen TV.
Y Pb Pr OUTPUT
Next, use the down arrow to select Y Pb Pr OUTPUT. This setting indicates the picture resolution you prefer 
when watching High-Definition programming. The choices, listed in order of highest to lowest picture resolution, are 1080i, 720p, 480p, and 480i. Your selection will depend on which format(s) your HDTV supports. 
To maximize your high-definition viewing experience, refer to your television set owner's manual, and use 
the right arrow button to choose the setting that indicates the highest picture resolution that your television 
will support.
4:3 OVERRIDE
Finally, use the down button arrow to select 4:3 OVERRIDE. By selecting 480i or 480p you are telling the HD 
settop box to send Standard Definition programming to your TV in its original broadcast format. Select OFF 
and the HD settop box will default to the resolution selected in the Y Pb Pr OUTPUT setting above. To exit 
and save changes press the POWER or MENU button. For more details on configuring your HD settop box 
output settings, including setting Closed Caption preferences, see the Motorola HD settop box User Guide or 
visit www.motorola.com/Broadband.
* If the On Screen Menu does not appear on your HDTV screen, your TV may not support the default, standard definition setting (480i). Use 
the HD settop box front panel LED to view and change your settings.
