XDS Metadata

Extended Data Services

Extended Data Services (XDS) is an American standard for the delivery of ancillary data (metadata) to television receivers. XDS metadata is carried in the CC3 and CC4 closed captioning channels (CEA-608).

Transform can insert the following types of XDS metadata:

  • V-chip Content Ratings
  • Program Information

V-chip Insertion

Use the Metadata Processor mplm filter to insert XDS V-chip metadata. For example the following composition inserts V-chip ratings into existing c708 caption metadata:

---
input:
  container:
  - name: input
    video:
    - name: v1
output:
  container:
  - name: output
    type: m2ts

    - route:
        name: v1
      sample_rate:
        numerator: 30000
        denominator: 1001
      filter:
      - type: mplm
