For those who aren't aware, Hollywood studios have been doing this for 5 years or so on their theatrical releases. Every title that goes out contains a track for both hearing impaired (boosted dialog, reduced sound effects) and visually impaired (a complete narration of what's on screen). Additionally, there's an on-screen caption track for theaters that wish to schedule entire screenings for the hard-of-hearing as well as an off-screen caption track that can be sent to hand-held or worn devices.
