Reliable

• No impact on authorized uses

• Low implementation cost

8

• Irreversible & tamper resistant

• High certainty of detection

Flexible

• Multiple embedding profiles

• Robust to distortion

• Low false positive rate

• Multiple data payloads


Window Protection

No Home Use Watermark State

For content “not intended for use in a home environment”

– Theatrical and Airline releases

Any use of No Home Use content by consumers is unauthorized

Device response is immediate

– Playback is stopped

– On-screen or front panel

10

– On-screen or front panelnotification is provided


For content “permitted to be used within an approved DRM only”

Verance maintains a list of approved DRMs for Trusted Source (TS)

– All DECE Approved DRMs to be included on list

– Additional studio-approved DRMs are also included

TS content should never be in “unapproved” format

– Must be distributed in format from list of approved DRM

Trusted Source Watermark States

11

– Must be distributed in format from list of approved DRM

– Must not be authorized for output or copying into any format not on list of

approved DRM

– Must carry “Copy Never” in CCI

– This ensures that authorized copies remain usable


Trusted Source Enforcement

Use of TS content in unapproved format is unauthorized

– Playback will be muted for 15 seconds with each TS enforcement

Response occurs when unauthorized use exceeds grace period

– Grace period measures repeated detection of mark across timeline of content

– Enables limited consumer use of unauthorized copies without restriction

– Provides flexibility for “edge” use cases ( “birthday party” scenario, etc.)

Grace period duration, calculation depends on TS modifiers

12

Grace period duration, calculation depends on TS modifiers

– Modifiers are manually selected during embedding, carried in watermark

– Grace period is 10 minutes for titles shorter than 1 hour, 20 minutes for

longer titles, according to Duration modifier (Long/Short)

– Measurement of “repeated detection of mark” varies according to

Enforcement Logic modifier (Primary/Secondary)


DECE Flag

A watermark bit can be designated to carry a DECE Flag

– DECE can establish eligibility criteria for embedding of DECE Flag in content

– DECE can require devices to protect only content carrying DECE Flag

AACS has employed a similar mechanism (AACS Flag)
