Producers who are creating spots that will have Described Video added should be aware of what this service is, who it is for, and how to best prepare and deliver elements to be used by the Extreme Reach team.
What is Described Video?
Described Video (DV) is audio-narrated descriptions of key visual elements. These descriptions are inserted into natural pauses in the dialogue. Described Video makes television more accessible to individuals who are blind or visually impaired.
Does Described Video change how I create an Ad?
Described Video is often added well after the production phase is complete, but this often presents a problem. Many ads feature “wall-to-wall” audio, which doesn’t leave any time for Described Video. In some cases there is no possible way to add any descriptions. Only people who have chosen to enable the SAP channel in their set-top box or television will hear the Described Video mix.
What elements should I supply to XR?
If we’re creating the Described Video for you and the mix contains enough free space to insert Described Video, only the final surround or stereo mix is required.
If you have a finished spot with Described Video, the Described Video must be on channels 3&4 for a stereo spot (stereo on 1&2) or on channels 9&10 for a surround plus stereo spot (surround on 1-6 and stereo on 7&8).
The Described Video track is broadcast on the Secondary Audio Program (SAP) channel that all broadcasters air alongside the regular audio channel. In a typical cable/satellite provider scenario, a television viewer can change a setting in the set-top box to switch the audio feed to the SAP channel. This stream could be labeled as “SAP”, “Described Video”, “Alternate Language” or “Audio Description” all these selections will provide the programming assigned to this alternate audio channel.
