DM100 Bitstream
Analyzer Dolby Laboratories’ new handheld DM100 Bitstream
Analyzer will allow audio system integrators and service engineers to
quickly test the integrity and composition of Dolby Digital (AC-3),
Dolby E, and PCM signals in a production facility, broadcast network,
or cable head-end. The DM100 also generates Dolby Digital, Dolby E,
and PCM test bitstreams. It has a built-in speaker and a headphone output
for monitoring any two channels simultaneously.
DP562 Multichannel Dolby Digital Decoder This unit is a multichannel
reference decoder for all Dolby Digital formats, including 5.1-channel
for digital TV and digitally implemented four-channel Dolby Pro Logic
decoding for audio encoded in Dolby Surround. The DP562 has an AES/EBU
input for monitoring Dolby Digital datastream or Dolby Surround PCM
signal, as well as digital and analog outputs. The unit allows monitoring
of all downmix and compression modes.
DP569 Dolby Digital Encoder with version 2.0 software The reference
multichannel Dolby Digital encoder is now available with new features.
Used in many cable uplink facilities, this new version includes an improved
menu system, new bitstream identifiers, additional downmixing settings,
new compression profiles and presets, automatic data rate selection,
a delay word for multiplexers, and improvements in audio coding quality.
Existing DP569 users can receive version 2.0 software free by registering
at www.dolby.com/tvaudio.
DP583 Frame Synchronizer Cable and satellite facilities routinely
need to synchronize externally generated Dolby Digital or Dolby E bitstreams
to match their internal plant reference. The DP583 accepts all Dolby
Digital and Dolby E frame and data rates, as well as PCM inputs, and
provides an output that is reframed to match the local plant reference.
The DP583 also allows postproduction facilities to reframe Dolby E streams
that have been stored on recorders that do not have video frame reference
capabilities, such as DAT.
"Dolby Laboratories provides cable TV broadcasters with an end-to-end
multichannel audio solution," said Tim Carroll, Product Manager, Professional
Audio, Dolby Laboratories. "Dolby also provides its cable TV broadcast
customers with excellent technical support services, resource information,
and marketing assistance."
