Some important information:
The joint Super Audio CD Disc Patent License Agreement comprises the essential patents of Philips and Sony. A worldwide list of the essential patents, together with applicable expiry dates, is attached to the agreement. Under the terms of the standard license agreement we only will require payment of royalties of patents where any of these are actually used – in other words, either in the country of manufacture or in the country of sale.
Super Audio CD disc licensees have at all times the option to transfer to the latest version of the Super Audio CD Disc Patent License Agreement. In the event of such transfer, we do not require payment of the entrance fee under the new license agreement.
Reference copies of the current version of the Philips Super Audio CD Disc Patent License Agreement, together with the relevant annexes, including worldwide patent lists, can be found in the patents/agreements section and the annexes section.
As part of new licenses and as part of settlement of disputes, manufacturers are now required to sign a side-letter setting forth the mandatory LSCD requirement. Such side-letters are also available to existing manufacturers wishing to demonstrate to their customers that they will only ship products covered by a valid LSCD issued by Philips. Manufacturers with this requirement are listed on Philips Licensee database with an asterisk (*). For more information about LSCD’s please visit our Supplier/Buyer page.
Patent countries and non-patent countries
As the patent list indicates, patents exist on national basis. Royalties are only due for products using a patent in the country where the patent exists, whether by manufacture, import, sale or otherwise.
Manufacturers based in countries where no essential patent exists, or due to expiry no longer exist, but whose products are distributed also in countries where the patent still subsists, may opt to enter into a Super Audio CD Limited License & Non Assertion Agreement covering such situation.
Manufacturers based in countries, where essential patents still exist may opt to transfer to the latest version of the Super Audio CD Patent License Agreement.
Super Audio CD
Super Audio CD takes digital audio sound quality to new levels, incorporating many of the best features of analog recording within a highly advanced digital technology.
Flexible distribution medium
The Super Audio CD format allows for three types of disc: single layer, dual layer and hybrid. The first two are high density (HD) formats which play only on Super Audio CD players, while the hybrid combines an HD layer and a conventional CD layer which makes the disc play in Super Audio CD- and standard CD players. With this variety of disc constructions, Super Audio CD is an extremely versatile format offering the creative community a wide choice of what to provide on a disc. Super Audio CD provides both superb stereo and multi-channel reproduction: with no down-mixing to stereo required in multi-channel mode, each of the six channels delivers full Super Audio CD quality for an outstanding three-dimensional listening experience.
As an example of the possibilities, a fully loaded hybrid Super Audio CD contains up to three complete 74 minute versions of the music:
- stereo Super Audio CD program
- multi-channel (5, 5.1, or 6 channel) Super Audio CD program
- stereo CD program and there is also a provision for content enrichments on the disc.
Hybrid format for backwards compatibility The hybrid construction supported by the SACD specification enables record labels to market discs containing both Super Audio CD and conventional CD content.
This potential for backwards compatibility means hybrid Super Audio CDs can be used in the massive installed base of almost one billion CD players. Consumers benefit from Super Audio CD's exceptional performance and multi-channel capabilities, while still being able to listen to part of the content on standard CD systems. The result is a distribution medium which safeguards consumer investments in their existing music collections and ensures a smooth migration path from standard CD to Super Audio CD.
Direct Stream Digital Interchange File Format (DSDIFF)
For optimum data transfer between the various Audio processing stages an interchange format is needed.
In the CD Audio domain PCM is the data format, and AIFF is the Audio Interchange File Format. For Super Audio CD Direct Stream Digital (DSD) is used as data format, and the interchange format is DSDIFF, which conforms as much as possible to the AIFF principles.

What is the SID code?
The CD replication industry developed a code system (SID code also known as IFPI code) to be employed by CD, DVD & SA-CD manufacturing plants to identify all discs mastered and/or replicated in their plant. Each CD-, DVD- and SA-CD manufacturing facility around the world has their own unique code and this enables the music industry to trace the origin of CDs.
The Source IDentification Code (SID Code) provides an optical disc production facility with the means to identify:
- all discs mastered and/or replicated in its plant;
- and the individual Laser Beam Recorder (LBR) signal processor or mould that produced a particular stamper or disc.
Each production facility that wishes to implement the use of the SID Code is issued with its own unique code(s). The SID Code was developed for use with the CD format, but is now being used for both CD and High Density disc formats, including DVD and Super Audio CD.
The SID Code was developed jointly by rights owners and the optical disc industry, primarily as an anti-piracy tool. However, since its introduction in 1994, the SID Code has proved a major benefit to optical disc producers. Its use both as a quality control tool and as a marketing tool has ensured that the SID Code, which was introduced on a purely voluntary basis, has now been implemented in over 80% of the world’s optical disc plants, representing over 90% of worldwide optical disc manufacturing capacity.
