Design
AirSpeed Multi Stream is designed for ease of use. Once the AirSpeed Multi Stream is
configured, based on your model, this video server captures up to four streams of video and
up to eight audio channel pairs for HD streams, and 4 audio channel pairs for SD streams to
a preselected Avid Unity workspace. The video standard (NTSC, PAL, 1080i, 720p) that you
select on the AirSpeed Multi Stream should be compatible with the editing systems used at
your site. The captured material is made available to Avid editing systems that use media
files compliant with Material Exchange Format (MXF).
A database in AirSpeed Multi Stream is a collection of clips, represented by thumbnail
images called headframes, and associated data. This data includes the name of the clip, notes
about its content, the dates captured, and so on. If the AirSpeed Multi Stream system has
multiple databases installed, or if you have many machines networked together, there can be
several folders in the Network Tree. A database can contain both SD and HD clips, as long
as they have related frame rates. For example, an NTSC 29.97 FPS clip can be in the same
database as a 1080i 59.95 FPS clip, and a PAL 25 FPS clip can be in the same database as a
1080i 50 FPS clip.
Depending on your model, the AirSpeed Multi Stream also supports up to four simultaneous
channels of playout. Select the AirSpeed Multi Stream’s host name in the Send To Playback
list on the Avid editing system and you can transfer a sequence to the AirSpeed Multi Stream
server. Then, use Avid iNEWS® Command to manage the playout of the sequence.
