Digital Video Recorder (DVR)

The DCX3510-M set-top is equipped with an internal hard drive for DVR (Digital Video
Recorder) functionality, which provides the ability to record both Standard Definition TV (SDTV)
and High Definition TV (HDTV) programs. Storage time varies based on the video format and
specific channel.
The DCX3510-M set-top is also equipped with an eSATA interface on the rear panel. This
interface allows the connection of an external hard disk drive to increase the DVR storage
capacity of the DCX3510-M. Note: your service provider must authorize your DCX3510-M for
external DVR functionality.
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 when switching between time-shifted and live TV.
The DCX3510-M model also includes integrated MoCA™ networking which supports wholehome DVR capabilities. This feature extends the DVR experience to DCX3200-M or other
compatible non-DVR set-tops with integrated MoCA, when enabled by application
software. On your non-DVR set-top you can now view your DVR recordings, playback content,
and set future recordings all from another room in your home.
With the DCX3510-M set-top, you can:
Record Programming. The total hours of recorded content will vary based on the storage
capacity of your DVR, the storage capacity of your specific external drive (if authorized), and
type of content (digital SD or HD and encoding method, MPEG-2 or MPEG-4) being recorded.

Using the External DVR Expansion Feature
To use the external DVR expansion feature of the DCX3510-M, first ensure that your service
provider has authorized your DCX3510-M for external DVR functionality. If authorized, follow
these steps to begin using the external DVR feature:
1. Power on your DCX3510-M and your television and ensure that you have a picture.
2. Connect a compatible eSATA hard disk drive to the DCX3510-M using the eSATA cable
supplied with your external drive enclosure. The DCX3510-M will automatically detect that
a hard disk drive has been connected to the eSATA interface.
3. The DCX3510-M will display an alert that an external hard disk drive has been connected
and that it must be formatted. Use the remote control to confirm the format (formatting a
drive will erase any and all content that on the drive).
4. The DCX3510-M displays a message when formatting is complete and if the operation
succeeded or failed.
During formatting of the external hard disk drive, the DCX3510-M will perform several tests to
determine if the hard drive’s performance is acceptable for DVR functionality. If the hard drive is
unable to pass these performance tests, the DCX3510-M will alert you that the external drive is not
compatible for DVR use.
5. The DCX3510-M will confirm that an external drive is connected and available for use.
While using the external DVR expansion feature of your DCX3510-M:

•

Recordings made on the external hard disk drive can only be played back on the same
DCX3510-M used to record the programs. You cannot connect your external hard disk
drive to another DCX3510-M (or another cable box with an eSATA interface) and watch
programs that have been recorded on the hard drive.

•

You can use multiple external hard disk drives with the same DCX3510-M, however; you
can only watch the recordings that are available on the drive connected to the DCX3510-M
at that time. To watch recordings that you made on another external drive, simply
disconnect the external drive, follow the on-screen prompts, reconnect the other external
drive, and again follow the on-screen prompts.

•

Whenever the DCX3510-M reboots, a temporary loss of the program listings in the
interactive program guide (IPG) is possible.

Use the guidelines below to determine the best video connection for your home
entertainment system.
Note: Only (1) video connection to the TV is required. HD video can only be viewed with HDMI, IEEE1394, or component video connections.

HDMI or IEEE-1394 — HDTV and SDTV
HDMI and IEEE-1394 offer higher quality HD video than component video.

•

If your TV has an HDMI input, this is for both audio and video. Connect a Standard HDMI
cable to the TV and to the HDMI connector on your DCX set-top.

•

HDMI and IEEE-1394 outputs provide video and audio, so no separate audio connections
are required if you plan to use your TV’s speakers as the primary audio source.

•

On-screen graphics will not be displayed when you are using the IEEE-1394 connection on
the rear panel of the DCX set-top. Refer to Section 6 for more information.

Native Mode Settings Screen
The Native Mode Settings menu is used to configure the operation of the native mode feature
on the DCX3510-M. The DCX3510-M is capable of receiving and decoding a number of
different digital video formats. When operating in native mode, the DCX3510-M generates the
video output format that most closely matches the broadcast video format.
For example, if the DCX3510-M is configured to operate in native mode, a channel broadcast in
the 720p format is output to the television in the 720p format, while a channel broadcast in the
1080i format is output to the television in the 1080i format.
When using the native mode feature of the DCX3510-M, please exercise caution when
selecting the formats from the checklist. If a format is selected that is not compatible with the
television, there may be a loss of video whenever the DCX3510-M is tuned to a channel that is
broadcast in that format.
If the television is connected to the DCX3510-M using an HDMI cable, the DCX3510-M
automatically customizes the checklist of supported formats reported to it by the television. If
the television is connected to the DCX3510-M using Component Video (YPbPr) cables, the
checklist needs to be customized manually.
Note: At least one of the [1080p - 1080i – 720p – 480p – 480i] formats must be selected from the
checklist for the DCX3510-M to operate properly in native mode.

HDMI/DVI Mode

Description
Allows you to optimize the HDMI output to work with both DVI-equipped televisions
and HDMI-equipped televisions. HDMI is the default setting.
• HDMI—Optimized to work with an HDMI television or home theater receiver.
• DVI—Optimized to work with a DVI television or display device (connected via an
HDMI-to-DVI adapter).

Color Space

Allows you to adjust the color space used by the DCX3510-M to generate the video
signals on the HDMI output. YCC 4:4:4 is the default setting.
• YCC 4:4:4—Generates video signals within the YCC color space.
• RGB—Generates video signals within the RGB color space.
Note: Adjusting these settings could result in a loss of video. Only a professional installer or
someone with a good working knowledge of the color spaces supported by the TV should
change this setting.

Audio Output

Allows you to specify the digital audio format delivered over the HDMI output by the
DCX3510-M. Options include Auto, L-PCM, and Pass Through. Auto option is the
default setting.
• Auto—Provides the digital audio format specified by the connected device (TV or
home theater receiver) when that device was first connected to the DCX3510-M.
• L-PCM—Provides all audio in the Linear Pulse Code Modulation digital audio
format. The L-PCM format is widely supported by most HDMI televisions and home
theater receivers.
• Pass Through—Provides the same digital audio format on the HDMI output as is
provided with the program being viewed at that time. For example, if the program
has a Dolby Digital soundtrack, the DCX3510-M passes the Dolby Digital audio to
the HDMI output. This option is most useful when connecting the DCX3510-M to a
home theater receiver that has HDMI switching capability.
Note: Adjusting these settings could result in a loss of audio. Only a professional installer or
someone with a good working knowledge of the digital audio formats supported by the TV
and/or home theater receiver should change this setting

Lip Sync

Allows you to adjust the amount of time the audio signal is delayed with respect to the
video signal on the HDMI output. Some HDMI televisions and home theater receivers
add an extra delay to the video signal during processing which can produce an effect
where the audio noticeably “leads” the video.
By default, this option is set to Auto. The options are used as follows:
• Auto—The DCX3510-M automatically delays the audio signal on the HDMI output
by the amount of time requested by the connected HDMI device.
• Manual—The DCX3510-M delays the audio signal on the HDMI output by the
amount of time selected for the Lip Sync Delay setting.
• Off—The DCX3510-M will not delay the audio signal on the HDMI output.

Advanced Audio/Video Settings Screen
The Advanced Audio/Video Settings menu customizes several advanced audio and video
features of the DCX3510-M, most notably the Dolby Volume feature and the Video Sharpness
feature.
The Dolby Volume feature provides volume normalization across channels, programs, and
commercials. Normalization is a process that adjusts the different volume levels across
channels, programs, and commercials to the same approximate output volume. As a result,

sudden volume changes are reduced and the overall volume output of the DCX3510-M is more
consistent.
The Video Sharpness feature softens or sharpens Standard Definition (SD) programs when
viewed on either the HDMI or Component Video (YPbPr) outputs. When SD programs are
viewed on a large screen television, picture quality can suffer because noise and other
imperfections in the picture can be magnified on the large display. The Video Sharpness
feature is used to soften the picture and reduce the appearance of these imperfections.

Troubleshooting

Before calling your service provider, review this troubleshooting guide. This information is to
help you quickly solve a problem. If your problem still exists, contact your service provider.
Problem
The DCX set-top will
not power on

Possible Solution
• The DCX set-top has received a software update and may not power on while the
new software is being installed. Try again in a few minutes.
• Verify that the AC power cord of the external power supply is connected to the DCX
set-top and an AC outlet. Unplug the DCX set-top from the AC outlet, plug it back in,
and then press the POWER button.
• If the DCX set-top is connected to a switched outlet on another unit, verify that that
unit is powered on. Unplug the power cord from the DCX set-top’s AC outlet, plug it
back it in, and then press the POWER button. Use an unswitched outlet, if possible.
• Press the POWER button on the DCX set-top front panel instead of the remote
control. The batteries in the remote control may be depleted.

The remote control
does not work

• Verify that the remote control is in “Cable” mode.
• Verify that there are no obstructions between the remote control and the DCX settop. Aim the remote control directly at the DCX set-top front panel, not the TV or VCR.
• The angle between the remote control and the DCX set-top may be too large. Stand
in front of the DCX set-top and not too far to either side.
• Press and release operation keys one at a time, firmly and deliberately.
• Check the batteries in the remote control. Install new batteries if needed.

There is no audio when
viewing cable channels

• Verify that the mute button on the remote control has not been pressed. Press mute
on the remote control to restore sound.
• If the DCX set-top audio output is connected to the TV, verify that the mute button on
the TV has not been pressed.
• If the DCX set-top audio output is connected to a home theater receiver, verify that
the receiver is set to the appropriate input source and the mute button on the
receiver has not been pressed.
• Verify that you have the correct cables for the audio connections.
• Verify that the audio cables are firmly connected between the DCX set-top and the
audio playback device (TV, receiver, DVD player, etc.).

There is no audio from
the center and/or
surround speakers of a
home theater receiver
connected to the DCX
set-top

Not all programs feature full Dolby Digital [5.1] or Dolby Digital Plus [7.1] surround
sound. In some cases, the programs may only contain left and right stereo audio.
• Verify that the S/PDIF cable (optical) is firmly connected to the DCX set-top and the
home theater receiver.
• Verify that the home theater receiver is set to a surround sound audio mode (Dolby
Pro Logic®, Dolby Pro Logic II®, Dolby Pro Logic IIx®).
• Verify that the receiver is properly configured to work with all connected speakers.

Troubleshooting
Problem
There is no video on
the TV screen

Possible Solution
• Verify that the TV is powered on and set to the appropriate input source for the DCX
set-top.
• Verify that the DCX set-top is powered on and tuned to an authorized cable channel.
• Verify that all video cables between the DCX set-top and the TV are firmly connected.
• Verify that the coaxial cable feed is firmly connected to the DCX set-top and the wall
jack.
• If the DCX set-top video output is connected to a home theater unit, verify that the
home theater unit is powered on and set to the appropriate input source.
• If the DCX set-top video output is connected to a TV through an HDMI connection,
power off the TV and then power off the DCX set-top. Wait one second and then
power on the devices.
• Not all HDTVs can display every output format (1080p60, 1080p30, 1080p24, 1080i,
720p, 480p, or 480i) available on the DCX set-top. To select a different format:
1. Ensure that your DCX set-top is plugged into a power outlet and is turned off.
2. Press the MENU key on the remote control. Your settings are displayed on the DCX
set-top front panel display.
3. Press the ▲ and ▼ keys to display the HDMI/YPbPr OUTPUT setting.
4. Press the ► key to cycle through the available output formats until a picture displays
on the TV.

No graphics or
program guides appear
on the TV screen

If you use the IEEE-1394 connection, on-screen graphics, including closed captions and
program guides, are not displayed by the DCX set-top. On-screen graphics and captions
may still be overlaid by your TV, if enabled. Alternatively, use HDMI or component video
instead.

No closed captions
display

• Verify on the User Settings menu that closed captions are enabled on the DCX settop.
• Verify that closed captions are enabled on the TV.
Note: Closed captioning may not be available on the current program.

There are black bars to
the right and left of the
picture

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 DCX set-top 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.

Troubleshooting
Problem
There are black bars
above and below the
picture

Possible Solution
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 DCX set-top is tuned to a
4:3 program.
• Set the TV TYPE to 4:3 Pan-Scan. This enables the DCX set-top 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 widescreen 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).

There are black bars on
all four sides of the
picture

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 DCX set-top cannot correct the video. You
may be able to minimize the border using the zoom feature on the TV.

Colors do not appear
correctly

Be sure to match up each signal to the same YPbPr connection on the TV, otherwise the
colors will not appear correctly on your TV.
