Active
Copyright Management System (ACMS) |
|
The new format should accept any data,
circuit, mechanism or IC required for the
Active Copyright Management System (ACMS). It
should also be compatible with any previous
copyright systems.
|
|
|
2 |
Copyright
Identification |
|
Data information required by ACMS and ISRC
(ISO3901) should be included in the digital
audio signal of the new format, and
transmitted through any digital output.
|
|
|
|
Pre-recorded discs should include SID codes.
The digital audio format should also provide
enough space to include copyright and
anti-piracy information data.
All recordable discs should be easily
recognisable to avoid confusion with
pre-recorded discs.
If possible, ISD codes should be written on
CD-Recordable discs.
All recording devices should generate and
record the following information :
 |
an
identification code to know the brand,
model and serial number of the recording
device |
|
an
extra code written on the disc, which
includes the total recording time of the
device and the number of discs which
have been recorded with this device
(there should be of course no
possibility to reset this counter) |
|
|
|
|
|
|
The new system should play back CD audio discs
(CD-DA).
Discs according to the new format should also
have a layer compatible with current
CD-players.
|
|
|
5 |
Audio,
video and data storage |
|
Beside audio, the new format should include
video and data areas.
|
|
|
|
There should not be any conditional access to
the audio content of the disc.
However, an additional content can be made
accessible by authorised people.
|
|
|
7 |
Highest
quality two-channel stereo and 6-channel
sound |
|
The new system should provide 8 independant
output channels with the following
characteristics :
|
2
high-quality stereo channels |
|
6
extra channels with the highest quality
allowed by disc space |
Losless
coding method should be used with a certified
algorithm
|
|
|
8 |
Archive
and master transfer without loss of
sound quality |
|
Audio data as available from today's masters
should be transferred to the new support
without any loss in sound quality. On the
other hand, the new format should propose
transfers to current digital audio format
(including 16-bits / 44.1kHz).
|
|
|
9 |
Extended
disc functions, including text |
|
These extended functions should provide
compulsory facilities (disc title, authors
names, tracks titles, tracks numbers and
index, video components, time information),
including many options
|
|
|
|
Packaging must not include any caddy or
cartridge
|
|
|
|
The new system should present a better
protection to minor alterations, like
scratches, than Compact Discs.
|
|
|
|
Single-sided disc is preferable
|
|
|
|
12cm diameter disc (4.75") is preferable
|
