Adding IEEE 1394 Devices Automatically, continued
1. Digital Video Signals
The TV is able to decode MPEG2 video. Other types
of digital video, such as DV video, provided by some
camcorders, must be decoded by the source device and
sent to the TV as analog video or S-Video. If the camcorder
uses a compatible digital control system, the IEEE 1394
cable can still provide control for the camcorder while the TV
is viewing the analog video or S-Video signals.
2. Digital Audio Signals
The TV is able to decode Dolby Digital signals and MPEG
Audio signals. “Other” types of digital audio as provided by
some digital recording devices,such as MP3 Audio and DTS
Audio, cannot be decoded by the TV when received over
IEEE 1394.
The TV may not be able to pass incompatible digital audio
signals on the coaxial digital audio output, however these
signals may pass on the IEEE 1394 cable to other devices.
3. Digital Control Signal
The TV is able to act as the control center for IEEE 1394
audio/video devices, such as VCRs, A/V Discs, tuners, cable
boxes and amplifiers that are compatible with the following
IEEE 1394 control standards.
• EIA-775 is designed for tuning devices such as cable
boxes allowing the device to send simple graphics.
However, this standard does not allow the TV to control
the cable box by IEEE 1394.
• AV/C (Audio Video Control) is designed to provide basic
controls such as play, stop, channel selection and volume,
as appropriate for the device. Some devices may have an
on-screen display for these functions.
• HAVi (Home Audio Video Interoperablity) is designed
to handle AV/C type of control. Some HAVi devices are
able to “teach” the TV how to control more than basic
functions, this allows the TV to control non-traditional
devices or new types of devices not yet developed. The
device will inform the TV what information and control
buttons will be needed on device specific menus so the
additional functions can be controlled. The ability to learn
new menus from a HAVi device is only available on the
following models: WS-55813, WS-65713, WS-65813 and
WS-73713.
Some devices may be a combination of two or more types of
devices. For example, there may be a recording device that
is also a tuning device. Each portion of the device is called a
sub-unit. When you select a device on the Device Selection
menu that has sub-units, a pop-up menu will appear so you
can select which sub-unit section you wish to use.
Compatible IEEE 1394 Devices
It is possible to connect devices to the TV that have IEEE 1394 connectors but are not compatible with the TV or with
the NetCommand
® control system. Areas of compatibility to consider are:
The TV is not able to control IEEE 1394 devices that use
other types of control protocols. Incompatible digital audio,
video and/or control information will still be able to pass
from one device through the TV to another device on the
network. These incompatible devices may not appear on the
Device Selection menu or in the Review screen of the Edit
NetCommand menu.
NetCommand Control of Digital
Devices Using the “Learn” Feature.
Some IEEE 1394 devices such as cable boxes or satellite
receivers will not have compatible digital control signals or
require the use of the device’s own remote control. Some
of these IEEE 1394 devices will not display on-screen
information through the IEEE 1394 connection and will
require using an analog connection for on-screen displays.
In many cases, to control these digital devices, the Learning
feature of NetCommand can be used.
1. Place an IR Emitter for NetCommand in front of the
device’s remote control sensor (see IR Emitters, page 26).
2. On the Name for 1394 Device screen (Figure 2, page 46)
check mark the Analog Connection check box.
3. Select the device type on the IEEE 1394 Device Type
screen (Figure 3, page 47) of cable box, DBS or similar
tuning device.
4. Select “Other” as a manufacturer and then highlight
“Learn” and press ENT(er) on the Device screen (Figure 4,
page 47).
5. Follow the device learning instructions found in Edit
NetCommand section of Chapter 3.
6. The Connection screen (Figure 5, page 47) follows the
learning screens. If analog connections are used, select
the correct inputs. If analog connections are not used,
uncheck the audio and video connections for both the TV
and AVR inputs.
7. Proceed with the Finish screen.
This will allow NetCommand to use the learned remote
control these IEEE 1394 devices.
Note: When using the NetCommand learning feature for
IEEE 1394 devices that do not have analog connections,
the GUIDE function will require pressing GUIDE twice.
The first press of GUIDE will display the TV’s digital
channel guide. The second press will display the
program guide for the device.
