...notes on Laserdisc connection
A Laserdisc source with a Dolby Digital RF output cannot be connected to this TV directly.
Also note that when using a Laserdisc player in conjunction with an RF demodulator to decode Dolby
digital sound, Hitachi recommend putting the Decode mode to DIGITAL. This will avoid dropping in
and out of analogue sound while searching or pausing the disc that is playing.
Pressing the INFO button on your handset reveals the format of the incoming signal not the
way it is being processed i.e. pressing the INFO key on the handset might reveal Dolby D 3/2.1,

standard Audio CD's.
This is the decode mode for a digital signal encoded by Dolby
Digital. This is capable of delivering a maximum of 5 main
channels (left, right, surround left, surround right and centre) and
a Low Frequency Effects (LFE) channel. Your television takes
advantage of data on the disc to tell you the number of different
channels available on the decoded track
DTS
This is the decode mode for a digital signal encoded by DTS.
This has the same capabilities as Dolby Digital and is displayed
when receiving a DTS encoded digital source.
This is the decode mode for digital signals encoded by MPEG.
MPEG tracks are either encoded as stereo or as having 5 main
channels plus a LFE channel
