BroadcastService

BroadcastService is a Service subtype for a TV network, radio station, or streaming broadcaster. It adds 10 broadcast-specific properties: broadcaster (the operating Organization), broadcastAffiliateOf (the parent network, for affiliates), callSign (the station call letters, e.g. "WABC"), broadcastFrequency (over-the-air frequency), broadcastTimezone (ISO 8601), broadcastDisplayName (the guide label), hasBroadcastChannel (the channels within this service), parentService (for regional variations of a national channel), videoFormat (SD, HD, 4K, IMAX), and inLanguage.

Service vs Channel

BroadcastService is the business/operational entity; BroadcastChannel is the distribution slot. A single BroadcastService can have many BroadcastChannels (cable, satellite, OTT) via hasBroadcastChannel.

Common BroadcastService mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    callSign with spaces or dashes

    Wrong
    "callSign": "W-XOO" or "WXOO FM"
    Right
    "callSign": "WXOO"

    Call signs are the registered short identifier (usually 3-4 letters). Broadcast-specific suffixes belong on broadcastDisplayName.

  2. 02

    Conflating BroadcastService and BroadcastChannel

    Wrong
    Using BroadcastChannel for the station itself
    Right
    BroadcastService for the station business, BroadcastChannel for the distribution slot

    The two are separate concepts. A single station (BroadcastService) may be on multiple channels (cable, satellite, HD subchannels).
