IEEE 1394 Devices Compatibility

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:

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

When received with video 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.

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.

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 22).

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 ENTER 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. For analog connections, select the correct inputs. If non using analog connections, uncheck the audio and video connections for both the TV and AVR inputs.

7. Finalize your choices with the Finish screen.

This will allow NetCommand to use the learned remote control signals to 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 will display the TV’s digital channel guide. The second press will display the program guide for the device, if an IEEE 1394 guide is available.
