Description.Abstract
Multimedia
applications
are
becoming
more
and
more
common
.
Possible
features
such
as
real-time
access
to
remote
data
,
combining
information
, and
customizing
presentations
create
a
large
potential
for
novel
uses
. On
today's
computers
and
networks
,
however
,
resources
are
still
scarce
for
real-time
processing
of
audio
and
video
.
Hence
,
good
quality
of
service
(QoS)
management
is
necessary
. The
preferred
quality
as
well
as the
appearance
of a
presentation
may
be
user
or
task
specific
.
Moreover
,
resources
are
shared
among
several
users
in
unpredictable
ways
,
requiring
adaptation
to
varying
resource
availability
. This
thesis
describes
the
architecture
of a
real-time
video
and
audio
player
integrating
approaches
to these
requirements
.
It
is
based
on a
QoS
model
of
independent
content
,
view
, and
quality
definitions
[31
,
33]
.
Authors
can
edit
the
content
of
presentations
.
Video
and
audio
clips
from
different
servers
can
be
combined
.
View
and
quality
is
controlled
in the
two
dimensions
of
temporal
and
spatial
resolution
. The
user
can
customize
the
appearance
by
adjusting
the
view
parameters
of
play
speed
and
image
size
.
Independently
,
frame
rate
and
image
resolution
control
the
quality
. A
feedback
mechanism
provides
automatic
adaptation
of the
frame
rate
to
resource
availability
. This
prototype
demonstrates
that
advanced
quality
of
service
control
and
support
for
complex
presentation
can
be
provided
and
shows
the
implementation
complexity
involved
.
