To avoid confusion with the Analog Real-Time Simulator project, the OST
ARTS project is now referred to as APE (or APERTS for short).  Version
0.1.0 is a major rewrite and restructuring of the RTS class hierarchy.

APERTS is the APE class library for Real Time Streaming.  APERTS includes
abstract classes to implement core support for RTP derived protocols as a
threaded stack, and is targeted at the development of streaming servers
such as VoIP gateways, network audio conference systems, etc.  APERTS is
derived from and does require the APE class library which may be found at
http://www.tycho.com/ape.  The APERTS software distribution may be found
either at ftp://ftp.tycho.com/pub/arts or ftp://www.voxilla.org/pub/arts.

The first question that has been asked is how APERTS relates to other
projects, such as Open H323.  First the goal of APERTS is a flexible
class library that can be used to implement a wide range of streaming
media services, and hence does not target nor will support a single
protocol family.  However, APERTS will not mearly include RTP streaming,
but also will over time support abstract classes to enable implementation
of all the various session management and control protocols one might
associate with projects such as Open H323, SIP, etc, and hence can be
thought of as a general purpose class library framework for the
development of expairemental streaming applications and internet
telephony services in general.

This initial release of APERTS covers the core base classes proposed for
the RTP framework, and their design as dual threaded sockets.  This
release of APERTS will be followed shortly with a functional RTP Audio
streaming class which will implement the common audio codecs, and
associated RTCP control.  After that, abstract classes will be introduced
for the common session management protocols.

While there is a concentration on the development of internet voice
telephony servers with APERTS, the goal is for APERTS to be general
purpose enough to use in the development of any kind of streaming media
applications including streaming video servers, mpeg broadcasting, etc.

The aperts home page will be initially started at
http://www.tycho.com/aperts, and will shortly thereafter migrate to Voxilla.
