Multimedia Audio on Demand

      This article describes a proposal for an audio server system
which allows the distribution of music or other audible information
to a token ring or ISDN attached front-end with sound representation
capabilities.  The audio server system has the following properties:

o   Allows one to get audio streams to Audio Client System
    (front-end) from a Host System (server)

o   Audio Client Systems are either attached via token ring or an
    ISDN network

o   Host Systems: ES/9000* with Workstation LAN File Services (WLFS)

o   Audio Client Systems: PS/2* with OS/2* Multimedia Presentation
    Manager (MMPM/2)

o   Either direct listening to stream of server (isochronuous
    transmission) or partial storage in Audio Client System  memory,
    hard disk

o   Audio streams: Digitized audio in CD quality like music (CD
    images), broadcast programs and shows, lectures etc.

o   Audio Client System  application program interface (API) allows
    for intelligent selection and online control

An overview of the system is shown in Fig. 1.

Scenario (Functions) - The Audio Client System  described in the
article offers the following functions.

      CD Import Management - The CD import management reads the CDs
from the CD ROM, translates the CD bit stream and builds a file per
CD title.  The file will be transferred compressed or uncompressed
via the SNA network to the Host System.  The Host System  compresses
the file and saves the data on a DASD in WLFS file format.  The Host
System  returns a token to the CD import manager.  With this token a
CD can be identified.  The token is also input for the -- Heading
'HCAT' unknown --.  Dependent on the data center organization billing
may be necessary.  The corresponding configuration and products are
shown in Fig. 2.

      Catalog Update Management - Catalog Update combines allocation
of new CDs or CD titles, administrator functions and billing.  The
administrator may allocate a new catalog entry, whenever necessary,
independent of an available CD file on the Host System.  With the
token returned to the CD import management, the catalog entry can be
connected to a CD file.  When the connection is defined, CD selection
and Play Control may select the CD.  The catalog entry describes the
kind of music, composer, performers, titles, etc.  The administrator
may also update the catalog any time, e.g., when billing rates are
changed.  Again these services may be billed.  The corresponding
configuration and products are shown in Fig. 3.

      CD Selection Management - The client or administrator may
select a CD or parts of a CD from the catalog and specifies a token
for the CD play management.  The Host System  returns an
acknowledgement including the notification that the requested data is
ready for transfer.  The selection may be saved in a profile.  The
client or administrator will be billed dependent on the...
