Dolby Media Producer Software Suite

Dolby Media Producer is a suite of professional software that supports all Dolby audio codecs used in mastering DVD-Video and

Blu-ray Disc

formats. It supports multichannel non-real-time encoding and le decoding of Dolby Digital Plus, Dolby Digital, Dolby

TrueHD, and MLP Lossless

formats via an intuitive user interface. The suite comprises six separate software products, including

Dolby Media Encoder, Dolby Media Decoder, Dolby Media Tools, and Dolby Media Meter.

Dolby Media Emulator

Dolby Media Emulator is a software tool that provides metadata authoring and emulation for Dolby broadcast audio formats. Paired

with popular digital audio workstations, Dolby Media Emulator enables you to emulate how your mix will sound when it’s played back

through a TV or set-top box. Dolby Media Emulator also simplies the monitoring of metadata for use with Dolby Digital Plus, Dolby

Digital, Dolby E, and High-Availability AAC (HE AAC).

DOLBY OEM MODULES

With Dolby OEM modules, you can easily and cost-eectively incorporate Dolby E and/or Dolby Digital Plus technology into your

products without having to develop your own Implementations. As the modules are fully assembled and tested by Dolby Laboratories,

there are no licensing or royalty fees involved. However, to ensure the interoperability and compatibility of your products incorporat-

ing Dolby modules, we reserve the right to test and approve them before you make them available for sale.

Except for the Cat. No. 561, Dolby OEM modules measure 116 x 51 mm (4.55 x 2 inches) and provide a 72-pin edge connector per

the JEDEC MO-116 SIMM specication. They can be controlled via control pins or a serial control port.

Cat. No. 561 Dolby Digital Plus Encoder Module

The Cat. No. 561 is capable of simultaneously encoding multiple channels of audio into Dolby Digital (AC-3), Dolby Digital Plus, and

HE AAC with Dolby metadata. It accepts PCM, Dolby E, Dolby Digital, and Dolby Digital Plus data in bit-serial (I

S) format, and

produces up to four encoded bitstream outputs, which can consist of multiple programs. It also supports transcoding Dolby Digital to

Dolby Digital Plus bitstreams; Dolby E to Dolby Digital Plus, Dolby E to HE AAC with Dolby metadata, and Dolby E metadata parsing

and decoding; and both serial port and GPI/O control.

Cat. No. 552 Multichannel Dolby E and Dolby Digital Plus Decoder Module

The Cat. No. 552 decodes Dolby E bitstreams with up to eight channels and Dolby Digital Plus bitstreams with up to six channels into

separate output channels. It can also downmix multichannel Dolby E and Dolby Digital Plus bitstreams into a stereo or Lt/Rt two-

channel output for monitoring purposes. It also passes PCM audio straight through, or applies Dolby Pro Logic decoding to derive L, C,

R, and S outputs from two-channel PCM programs. The Cat. No. 552 features two metadata outputs: one provides a full metadata set

for use with downstream Dolby E or Dolby Digital Plus encoders, while the other provides a metadata subset designed for OEM use in

the display of key metadata parameters.

Cat. No. 559D Dolby Digital Multichannel Encoder Module

The Cat. No. 559D provides up to 5.1-channel Dolby Digital encoding with bit rates from 56 to 640 kbps and sampling rates between

32 and 48 kHz. Metadata can be internally generated or received from externally generated sources, and a metadata subset output is

available for the display of key metadata values.

Cat. No. 559E Dolby E Encoder Module

The Cat. No. 559E provides up to eight channels of Dolby E encoding and supports up to 20-bit word lengths at a 48 kHz sampling

rate. The Cat. No. 559E can be controlled via control pins or a serial control port, and can pass through PCM audio signals. Externally

generated metadata can be accepted into the module, or metadata can be internally generated. A metadata subset output is available

for OEM use in the display of key metadata values.
