Compatible A/V devices include some, but not all, cable boxes,
1. Digital Video Signals
The TV is able to decode MPEG2 and DV video as provided by some camcorders. If the TV is unable to decode the digital signal supplied by your camcorder, try
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 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.
•
•AV/C (Audio Video Control) is designed to provide basic controls such as play, stop, channel selection, and volume, as appropriate for the device.
The IEEE 1394 interface may not provide reliable control signals for some DV camcorders, especially older models. If your camcorder operates incorrectly or not at all, use the camcorder’s control buttons instead of the IEEE 1394 connection.
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
When Connecting IEEE 139 Devices
•Do not loop the last device in the chain back to the TV. When the device chain is looped, the TV may not be able to work with the other devices.

•Place devices that have only a mechanical (two- position) power switch at the end of the chain or leave the power switch in the On position. When turned Off, IEEE 1394 signals may not be able to pass through the device to other devices.
•Place devices with the slowest communication speed at the end of the chain. Sometimes the communication speed will be marked near the IEEE 1394 connector with an “S” number. The higher the number, the faster the communication speed. This TV has a communication speed of S400. Devices with slow communication speed can interfere with IEEE 1394 signals from faster devices. When using NetCommand to set up a digital recording between a faster device and a slower device, make the slower device the source and make the faster device the recorder.
•Do not use an IEEE 1394 cable over 15 feet in length between each device.
•This TV is an IEEE 1394a device. It can be used with a 1394b system when an
IMPORTANT
DV Camcorder Notes
A.When viewing DV camcorders, it is normal for temporary audio and video distortion to occur under conditions such as:
•Playback start and stop
•Playback pause
•Forward or reverse picture search
B.Some DV Camcorder models are not compatible with this TV’s IEEE 139 system and the “New 139 Device” screen will not appear when
the camcorder is connected. For playback of incompatible DV camcorders, try
C.TV Disc cannot record DV video. Record DV video on an IEEE 139 device designed to record DV video.
