Compatible Ieee 1394 Devices

Adding IEEE 1394 Devices Automatically

It is possible to connect devices to the HDTV Receiver that have IEEE  connectors but are not compatible with the

HDTV Receiver or with the NetCommand® control system. There are three areas of compatibility to consider:

1. Digital Video Signals

The HDTV Receiver is able to decode MPEG 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 HDTV Receiver as analog video or S- Video. If the camcorder uses a compatible digital control system, the IEEE  cable can still provide control for the camcorder while the HDTV Receiver is viewing the video or S-Video signals.

2. Digital Audio Signals

The HDTV Receiver is able to decode Dolby Digital signals and MPEG Audio signals.

Other types of digital audio such as MP Audio and DTS Audio, as provided by some digital recording devices, cannot be decoded by the HDTV Receiver.

The HDTV Receiver may not be able to pass incompatible digital audio signals on the coaxial digital audio output, however these signals may pass on the IEEE  cable to other devices.

3. Digital Control Signals

The TV is able to act as the control center for IEEE  audio/video devices, such as VCRs, AV Discs, tuners, cable boxes and amplifiers that are compatible with the following IEEE  control standards.

•EIA-is designed for tuning devices such as cable boxes allowing the device to send simple graphics. However, this standard does not allow the HDTV Receiver to control the cable box by IEEE .

•AV/C (Audio Video Control) is designed to provide basic controls such as play, stop, channel selection and volume, as appropriate for the device.

•HAVi (Home Audio Video Interoperablity) is designed to handle AV/C type of control and allows each device to “teach” the HDTV Receiver how to control more than simple basic functions. The device will inform the HDTV Receiver what information and control buttons will be needed on device specific menus so the additional functions can be controlled. The ability of a device to “teach” the HDTV Receiver how to control new functions allows the HDTV Receive to control non-traditional devices or new types of devices not yet developed.

Some devices may be a combination of two or more types of devices. For instance, 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 HDTV Receiver is not able to control IEEE  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 HDTV Receiver 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.
