DIGITAL VIDEO RECORDER (DVR)

The DCT3400 contains a hard drive for the digital video recorder (DVR)
to record standard- and high-definition TV (HDTV) programs.

A standard VCR records and plays analog video. DVR records and plays
digital video. Unlike an analog tape, the hard drive allows simultaneous
recording and playback.

A DVR offers the ability to control your viewing experience by pausing
(time shifting) live TV and providing trick playback modes (pause, fast
forward, slow forward, fast rewind, slow rewind). You may experience a
slight delay between time shifted and live TV.

With the DCT3400, you can:

Record Programming

Record hours of TV programming. The total hours of recorded content
depends on your hard drive capacity and content type (digital, analog, or
HD) that you record.

Maintain a Personal Program Library

Maintain a personal library of recorded programming, accessed using the
interactive program guide (IPG).

Control Live TV

Pause, rewind, or fast-forward live TV.

Simultaneously Watch Two Programs

Watch two programs and easily switch between them using the
key on your remote control. (Dependent upon program guide support.)

Simultaneously Watch and Record

Record one program in the background while viewing another live
broadcast at the same time.

Simultaneously Record Two Shows

Record two programs from two different channels at the same time.

Simultaneously Record Two Shows and Watch a Recorded Program

Watch a recorded program while recording up to two other programs at
the same time. You can also easily switch viewing the pre-recorded
program and either of the programs you’re recording.

13

Video Connection Options

The DCT3400 offers the following video outputs:

HDTV
Standard

Component video, HDMI, or IEEE 1394

Composite video, S-Video, or RF coaxial

To determine the available inputs on your TV, check the manual supplied
with the TV or the TV itself.

Use the following guidelines to determine the best video connection for
your home entertainment system:

• Component video (Y Pb Pr) – HDTV and standard

The Y, Pb, and Pr outputs provide component video, which is the
most widely supported HDTV connection.

• HDMI or IEEE 1394 – HDTV and standard

HDMI and IEEE 1394 offer higher video quality than component
video. If your TV has an HDMI input, use the HDMI output instead

of IEEE 1394. Motorola recommends using HDMI cables less than
20 meters long.

HDMI and IEEE 1394 are video and audio connections. If you use

HDMI or IEEE 1394, no separate audio connection to your TV is
required.

HDMI is compatible with DVI. If your TV has a DVI input, you can

use an HDMI-to-DVI converter cable to connect to the DCT3400

HDMI connector.

If you use IEEE

1394, on-screen graphics do not display.

• S-Video – standard only

If your TV has an S-Video input, use S-Video. S-Video is the
highest quality standard-definition video output on the DCT3400.

• Composite video – standard only

If your TV does not have an S-Video input, use the composite
video (

VIDEO) output.

• RF coaxial – standard only
If your TV only has a coaxial RF input, connect it to the DCT3400

RF OUT connector.

If the cable terminal is connected to a TV through its
HDMI connection, power off the TV and then power off
the cable terminal. Wait one second and then power on
the devices.

Not all HDTVs can display every output format (1080i,
720p, 480p, or 480i) available on the cable terminal. To
select a different format:

1 Ensure that your cable terminal is plugged into a

power outlet and is turned off.

2 Press the

DCT3400 User Guide

Problem Possible Solution

There are black

There are black
bars above and

Wide screen TVs display 4:3 programs in this format
unless set to Stretch. Turn on the 4:3 OVERRIDE feature
in the User Settings menu. This enables most wide
screen TVs to stretch the video to fill the screen (see
your TV manual for information about stretching 4:3
video).

If the cable terminal is connected to a wide screen TV,
verify that the TV TYPE is set to 16:9 in the User
Settings menu.

Many HD programs are broadcast in pillar-box format
with black bars to the left and right of the picture. These
programs are broadcast in 16:9 HD formats even though
the video is not 16:9.

All 4:3 HDTVs display HD programs in letterbox format
(black bars above and below the picture) because of the
shape of the display screen.

Turn on the 4:3 OVERRIDE feature in the User Settings
menu. This enables most standard screen TVs to display
a full screen picture when the cable terminal is tuned to a
4:3 program.

Set the TV TYPE to 4:3 Pan-Scan. This enables the
cable terminal to remove the black bars above and below
the picture when possible.

Some SD programs are broadcast in the letterbox format
with black bars above and below the picture. Some wide
screens TVs offer a zoom feature that may be able to
remove the black bars (see your TV manual for
information about zooming 4:3 video).

33

Problem Possible Solution

There are black
bars on all four
sides of the picture

The cable terminal
is making a
humming noise.

This may occur on a 4:3 TV if the 4:3 OVERRIDE setting
is OFF. To set 4:3 SD programming to fill the screen,
depending on the capabilities of the TV, set
4:3 OVERRIDE to 480i or 480p.

This may occur on a 16:9 TV if the active video for an SD
broadcast is in letterbox format. To confirm, wait for a
commercial or look for a graphic, such as a network logo.
If the commercial fills the screen from top to bottom, or
the graphic appears below the active video, the program
is being letterboxed by the broadcaster. You can
minimize this by activating the zoom feature on the TV.

A broadcaster may include black bars on either side of a
wide screen broadcast. This is called a “hybrid” aspect
ratio and results in a black border surrounding the video
on a 4:3 TV. Because this is part of the broadcast, the
cable terminal cannot correct the video. You may be able
to minimize the border using the zoom feature on the TV.

The DCT3400 includes an integrated hard drive and a
fan for cooling. During normal operation, the DCT3400
emits a low humming noise, similar to a personal
computer. The noise varies in volume occasionally when
the speed of the internal fan adjusts to changes in the
temperature around the DCT3400. Please note the hard
drive will stay on even when the DCT3400 is turned off.
