Embedded Audio (Option)

Introduction

The Embedded Audio option for Image Servers is available as a factory-installed option, or

as an update for certain models of Image Server already in service. Embedded audio is based on

SMPTE 272M-A. Key features include:

Synchronous 20-bit audio at a 48K sample rate. Non-synchronous audio and other sampling
rates are not supported.

While up to 16 channels of audio may be present in an SDI stream (arranged in 4 groups of 4

channels), the Image Server records and plays back only Group 1 audio channels (channels 1-4).

In E-E mode, all embedded audio will pass through the Image Server unaltered.

The user can select audio to record from either a +4 analog, AES/EBU digital, or embedded

audio source. Mix-and-match among inputs is not supported.

Embedded audio is always included in the SDI stream on playback, and audio will
simultaneously appear on the AES/EBU or analog audio outputs, as selected by the audio card

option jumpers. When analog audio is selected, only channels 1 & 2 will be available at the

output.

User bits in the SDI embedded audio stream are not supported.

Setup

A software key is required to enable the Embedded Audio option. When purchased as a

factory installed option, the Image Server will ship with the key already entered and the Embedded

Audio option enabled. It will also include a certificate that contains the unique key code used to

enable Embedded Audio. Store this document in a safe location for future use.

If you have purchased Embedded Audio as an add-on to an existing Image Server, or if you

need to re-enter the key code for any reason, use the following instructions to enable Embedded

Audio.

From the main Image Server GUI window, click on Configure > Options…
