IEEE 1394 Devices

Compatible IEEE 1394 Devices

Compatible A/V devices include some, but not all, cable boxes, D-VHS VCRs, A/V discs, and future products. Some devices may have IEEE 1394 connectors but are not compatible with the TV. Areas of compatibility to consider are:

1. Digital Video Signals

The TV can decode MPEG2 video as provided by cable boxes and some camcorders. Many camcorders provide DV video, which the TV cannot decode. Connect a DV camcorder to the TV using analog audio plus composite video, S-video, or component video, or use HDMI audio/ video. Other types of digital video, such as PC video provided by some computers, must be decoded by the source device and sent to the TV as analog video, S-video, or DVI/HDMI video.

2. Digital Audio Signals

When received with video signals, the TV can decode Dolby Digital signals and MPEG audio signals. Other types of digital audio as provided by some digital record- ing devices, such as MP3 audio and DTS audio, cannot be decoded by the TV when received over IEEE 1394 con- nections.

The TV may not be able to pass incompatible digital audio signals on the coaxial digital audio output. These signals may pass to other devices, however, on the IEEE 1394 cable.

3. Digital Control Signal

The TV can serve 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.

4-pin connector 6-pin connector 6-pin-to-4-pin adapter

If you wish to connect a 6-pin device to the TV (such as a camcorder), and the device is designed to receive electri- cal power from another 6-pin device, there are several ways to provide electrical power to the device:

•Connect the camcorder directly to the household AC.

•Use the camcorder’s battery for power.

•Connect the camcorder directly to another 6-pin device in the network that can provide power.

Connection Methods

There are two connection methods for IEEE 1394 devices. Use the method that fits your network of audio/video products.

Direct Device-To-Device Method

The IEEE 1394 interface allows you to chain devices, unlike audio and video connections that require you to connect each individual device directly to the TV. For example, you can connect your D-VHS to your 1394 A/V disc and then connect the 1394 A/V disc to the TV. The resulting IEEE 1394 chain allows you to add more devices to the chain. You will see an icon for each device in the TV’s Input Selection menu and can also send information from any IEEE 1394 device to other compatible devices.

• EIA-775.Designed for tuning devices such as cable

boxes, allowing the device to send simple graph-

ics. This standard does not, however, allow the TV to

control the cable box by IEEE 1394.

• AV/C (Audio Video Control). Designed to provide

basic controls such as play, stop, channel selection,

and volume, as appropriate for the device.

Four-Pin and 6-Pin Connections

There are two different types of connectors used for IEEE 1394 terminals and cables: a 4-pin and a 6-pin type. Both

The IEEE 1394 standard allows you to use the TV as a hub within the audio/video network. Each device can send information, which may include audio and video, to any other device in the network.

types send the same digital audio, video, and control signals, but the 6-pin connectors can also supply low- voltage electrical power to connected devices. This TV uses only 4-pin type connectors.

A6-pin connector cannot be connected directly to a 4-pin jack, and vice versa. To connect a 6-pin device to a 4-pin device, use a 6-pin-to-4-pin adapter or adapter cable.

These cables are available from electronics and computer stores.
