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 everyone1
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 MSAudio, etc).

  • 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 MSAudio, etc).

  • 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 principles1
Core Principles MSAudio, etc).

  • 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 principles2
Core Principles MSAudio, etc).

  • 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 principles3
Core Principles MSAudio, etc).

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 principles4

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 principles5
Core Principles technologically protected

  • 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 principles6
Core Principles technologically protected

  • 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 principles7
Core Principles technologically protected

  • 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 technologically protected

  • 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 technologically protected

  • 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 technologically protected

  • Logo and Tagline for SDMI Compliant products.


Expectations
Expectations technologically protected

  • 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.


Announcements to date
