Optimum disc playability :
ensuring excellent picture quality
Philips components and modules for the various
CD applications have always enjoyed an
excellent reputation in the market place for
super disc playability - the ability to play discs
which may be scratched, soiled or not fully
according to the standard specification. This
position has been underlined by tests showing
the superior performance of the various Philips
players, as well as by the positive experiences of
millions of individual consumers around the
world.
Constantly improving performance
As the penetration of the CD system has
increased, and new applications like CD-ROM
and Video CD have become commonplace,
Philips Components - as the CD technology
inventor and as one of the major suppliers of
CD player modules in the industry - has
constantly improved the performance of its
products.
One of the ways in which this benefits users is
by optimum disc playability. This is an important
parameter for CD players other than CD Audio,
and especially for the Video CD applications,
because any loss of data from the disc will at
best cause disturbances in the reproduced
picture, and at worst can cause the player to lose
track so that disc playing fails.
Presenting Super Error Correction
To ensure consistently good results when playing
Video CD discs of all quality grades and
conditions, Philips has introduced further
improvements in the system's playability. These
developments together are called Super Error
Correction, a proprietary Philips technology
optimizing the system's ability to handle less-
than-perfect discs with the minimum disturbance
to normal playing.
By effectively eliminating virtually all errors arising
under normal playing conditions, Super Error
Correction ensures that the picture quality as
seen by the user is independent of disc play. The
video encoding and processing during mastering
of the disc, and the MPEG-1 decoding and video
encoding in the signal processing stages, are now
the only limiting factors for picture quality.
