the path to sdmi
The Path to SDMI
  • 1970’s: Tape recorders
  • 1980’s: DAT
  • 1990’s:
    • CD-R; CD-RW
    • Recordable DVD
    • Storage capacity
    • Small, portable, removable hard drives
    • Flash memory devices
    • MP3 files
confrontation to collaboration
Confrontation to Collaboration
  • Legal rights difficult to enforce
  • Need for technological solution
  • Need for collaboration to allow a legitimate market to emerge
benefits of collaboration
Benefits of Collaboration
  • New business models for music usage can develop
  • New products and services can be created to support these new uses
  • Consumers gain
    • easier access
    • to more music
    • in new, more enjoyable ways
pirate markets benefit no one
Pirate markets benefit no one
  • Piracy-based markets are short-term only; consumer frustration hurts everyone
  • If content loses value, technology driver is lost
  • Lost opportunity for e-commerce
legitimate markets benefit everyone
Legitimate markets benefit everyone
  • Easy access to music
  • Easy to acquire
  • Quality sound
  • New ways to use music
  • Interoperable devices
legitimate markets benefit everyone19
Legitimate markets benefit everyone
  • Companies that make products
  • Artists who make music
  • Consumers who want both
goals of sdmi
Goals of SDMI
  • To secure music in all forms, across all delivery channels
  • Brand music with indelible markings, at the source
  • Identifiers and usage rights data travel with music
  • All devices read and act on data in predictable ways.
sdmi is commercially motivated
SDMI is commercially motivated
  • Not intended to reinvent
  • Intended to build on what has already been achieved and what is already available in the market
short term need portable devices
Short term need: Portable Devices
  • Customer demand
  • Technology partners eager to join that market
  • Internet could otherwise turn into a permanent haven for pirated music
  • Therefore, portable device issue had to be addressed on a very fast track
sdmi on concurrent tracks
SDMI on concurrent tracks
  • Short term needs requiring prompt resolution: Portable devices on a fast track
  • Long term objective: Meta-level architecture
sdmi s launch
SDMI’s Launch
  • February 26, 1999
  • Executive Director - Leonardo Chiariglione
    • Chair of MPEG
  • Portable Device Working Group
    • Immediately tasked with focusing on Portable Devices
    • Jack Lacy, Chair
    • Met June 30, 1998 deadline for initial Portable Device Specification
portable device specification version 1 0
Portable Device Specification Version 1.0
  • Adopted June 28, 1999
  • Released July 13, 1999, after technical review
  • Publicly available, along with overview and FAQ, at
sdmi framework not format
No intent to select a compression technology (MP3, AAC, MSAudio, etc).

No intent to select an encryption technology.


Technology is continually developing and will improve.

Encourage innovation and competition.

Allow maximum flexibility.

Allow market to choose the best formats.

SDMI- Framework, Not Format
pd specification covers
PD Specification Covers
  • Application
    • Program that manages import of content, music libraries, playback and rights management
  • Portable Device (PD)
    • Device that stores protected content and plays it back
  • Portable Media (PM)
    • Media that stores protected content
  • Licensed Compliant Module (LCM)
    • Interfaces and/or translates communications between LCMs and PDs/PMs
core principles
Core Principles
  • SDMI components must respect any “usage rules” - which describe how the content can be used - that may come in the content in the future.
    • Any artist, band or record label that chooses to permit unlimited copying will have that option.
    • Any artist, band or record label that chooses to limit copying of an original will have that option.
    • This is a general principle for future application (e.g. electronically distributed music), not current product.
core principles29
Core Principles
  • Any content to be used in an SDMI Portable Device must be protected at all times after it has been imported into the SDMI domain.
  • Subsequent storage, use within, or transfer between SDMI components must be done in a manner that protects the content.
core principles30
Core Principles
  • Content must be bound to a Portable Device or Portable Media.
    • This ensures that a copy on a PD or PM will not become the source for additional copies.
    • This does not limit consumer usage because consumers can make copies for any device they choose - and as many devices as they need - and portable media can be transferred among compatible devices.
core principles31
Core Principles

SDMI components will accept both protected and unprotected music, e.g. MP3 files.

  • Unknown, unprotected music will be converted into SDMI content and stored in protected form.
  • Music from unknown sources (garage bands, church choirs) will not be excluded.
core principles32
Legacy content (music on existing CDs) will not be technologically protected.

Reasons:- Effective protection is not possible.- Technological impediments would merely be minor speed bumps to copying.- Necessary in order to permit church choirs and garage bands to use SDMI.- Respects privacy rights.

Core Principles
core principles33
Core Principles
  • Future content (music on future CDs, DVD-A and EMD) must be protected against Internet piracy.
    • Mechanism for protection yet to be determined.
    • One way this could be done is through a Dual Watermark System.
      • Robust watermark - will not degrade when compressed.
      • Fragile watermark - will disappear when compressed.
      • All music from unknown source passes through screen in SDMI application. Screen only permits in content that either has both marks or no marks.
core principles34
Core Principles
  • Personal copying of CDs is permitted; Internet distribution without authorization is prevented.
  • Where “usage rules” are not found, SDMI components will only make 4 copies from every rip from the original. This allows personal copying - as much as necessary - but impedes piracy.
core principles35
Core Principles
  • SDMI technology must be robust.
    • Security mechanisms must achieve certain requirements.
    • Tamper resistance in both software and hardware.
    • Content must be protected whenever exposed.
  • Devices to develop in 2 phases.
  • 1st Phase
    • Screen music for a signal - time to upgrade to become a 2nd Generation device.
  • 2nd Phase
    • Dual Watermark or other system
    • Only upgraded phase 2 devices will play future releases.
compliance with the standard
Compliance with the Standard
  • Compliance is a condition of obtaining a trademark license to use an SDMI mark.
  • Compliance is a condition of obtaining a technology license for the Aris/4C watermark.
marketing efforts
Marketing Efforts
  • Logo and Tagline for SDMI Compliant products.
  • Some manufacturers have already announced plans for SDMI compliant products, and they should begin coming to market by January, 2000.
  • Goal and expectation is that SDMI compliant products will overtake non-compliant products within a few years.
