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 www.sdmi.org
sdmi framework not format
No intent to select a compression technology (MP3, AAC, MSAudio, etc).

No intent to select an encryption technology.

Reasons:

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.
implementation
Implementation
  • 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.
expectations
Expectations
  • 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.
