Accessibility Compliance

Compliance Requirements Matrix

Regulation	Scope	Requirement	Deadline
ADA Title II	US state/local government	WCAG 2.1 AA	Apr 2026 (50k+ pop), Apr 2027 (<50k)
Section 508	US federal agencies	WCAG 2.1 AA	Ongoing
WCAG 2.1 AA	Web content	1.2.2 (pre-recorded captions), 1.2.4 (live captions)	Standard
EAA	EU audiovisual services	Accessible multimedia	June 2025
CVAA/FCC	US broadcast + online video	Closed captions on distributed content	Ongoing

Caption Quality Standards

FCC caption quality requirements:

• Accuracy: Captions must match spoken words and non-speech sounds
• Synchronicity: Captions must coincide with dialogue and sounds
• Completeness: Captions must cover the entirety of the program
• Placement: Captions must not obscure visual content

Machine vs Human Accuracy

• Machine (REACH ASR): ~83-87% accuracy. Use as a starting point, then upgrade to human captions for full ADA/Section 508 compliance.
• Human (REACH professional): 99%+ accuracy. Meets ADA, Section 508, WCAG 2.1 AA, and FCC requirements.

Best practice: Auto-caption with machine ASR for immediate availability, then upgrade to human captions for compliance.

Audio Description via REACH

For visually impaired users, REACH supports audio description:

• serviceFeature: 4 (AUDIO_DESCRIPTION) — standard
• serviceFeature: 9 (EXTENDED_AUDIO_DESCRIPTION) — extended pauses
• Set usage=1 (EXTENDED_AUDIO_DESCRIPTION) on the CaptionAsset

Accessibility Audit Pattern

Bulk-check caption coverage across a library:

# Step 1: List all entries
curl -X POST "$KALTURA_SERVICE_URL/service/media/action/list" \
  -d "ks=$KALTURA_KS" \
  -d "format=1" \
  -d "filter[objectType]=KalturaMediaEntryFilter" \
  -d "filter[statusEqual]=2" \
  -d "filter[mediaTypeEqual]=1" \
  -d "pager[pageSize]=500"

# Step 2: For each entry, check caption assets
curl -X POST "$KALTURA_SERVICE_URL/service/caption_captionAsset/action/list" \
  -d "ks=$KALTURA_KS" \
  -d "format=1" \
  -d "filter[objectType]=KalturaAssetFilter" \
  -d "filter[entryIdEqual]=$KALTURA_ENTRY_ID" \
  -d "filter[statusEqual]=2"

# Step 3: Flag entries with totalCount=0 as needing captions
# Step 4: Order REACH tasks for uncaptioned entries
