Silver Stream-In/Stream-Out at a Glance
2.0
This section provides an overview of the Silver IP Encoder (Stream-In) and the IP Decoder
(Stream-Out). It outlines how you can start using these Codecs to send audio. Section 3 con-
tains more detailed information on the operation and how the Codec systems can be con-
trolled by the new WEB based Management System.
2.1
Introduction
The Silver audio Codec range is based on the new APT Codec core engine. This new engine is
designed to be as flexible and versatile in use as possible. The core is powerful and address-
es more than ever the needs of professional IP audio transmissions.
The set of Silver Stream-In and Stream-Out can be used to setup a full duplex link. The Sil-
ver Codec range consists of the Encoder (Stream-In) and the Decoder (Stream-Out) as sepa-
rate units in a ½ 1U format.
As a multi-algorithm audio Encoder or Decoder it is offering conventional analog left and
right audio connections operating through IP. These analog audio connections are carried out
for semi-professional phone jacks or as professional XLR connectors.
In the first instance the new Codec generation incorporates the enhanced versions of the
apt-X
®
algorithm (real time transmission on the network with data reduction by factor 4:1)
and Linear PCM 16 and 24 bit. More audio algorithms will be available optionally on coming
firmware releases.
The units are capable of delivering high quality audio used for inter-studio networking, re-
mote/outside broadcasts and STL/TSL monitor applications. Enhanced apt-X® offers 16 and
24 bit operation as an improvement over the performance of the original standard 16 bit apt-
x
®
algorithm.
Audio modes and bandwidths are dependent on the network bit rate, the algorithm, mode
and frequency response selected and the bit resolution of the desired audio. Bandwidths will
range from 3.8 to 22.5 kHz in stereo mode and 7.6 to 22.5 kHz when set for mono operation.
The Silver Codec range runs an embedded WEB GUI which can be accessed from a web
browser. It will be also fully software driven via APT's WorldCast Codec Management System
which runs on a PC connected via LAN or WAN. A headphone socket provides for additional
monitoring of the audio input or the output.
An Additional interface allows for the connection of auxiliary data terminated on a DB-9way
connector. Regardless of using the Encoder (Stream-In) or the Decoder (Stream-Out) the
AUX Data link is provided always as a duplex link (while the audio is always simplex).
The Silver Stream-In and Stream-Out come with the SureStream option applied as standard.
Both units are very similar with the exception that the Decoder offers an additional USB port
for future use (e.g. playing out stored audio files).
