Using Embedded Audio
Embedded Audio is an available option on Image Server 2000. It is based on SMPTE standard
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
analog output. Embedded channels 3 and 4 are not affected.
User bits in the SDI embedded audio stream are not supported.
•
20 bit Dolby E is supported
•
Configuring Embedded Audio
