This video (spanish) about the audiodescription to blind People in the
cinema or socialroom. I think is the answer at your request.

>> Thank you Charles, David, Thank you for this great conversation!
>> David I think it would be great if you could reach out to the folks at
>> accessible media and see what they know or have to say about it – surely
>> they looked into this?
>> Charles I love your workaround – totally in favour of an extra TV for
>> every blind Canadian :-)
>> It does work in the theater, I use that function all the time. I had not
>> realized that the technology was not included in consumer electronics Dash
>> that is a barrier but also seems quite an oversight. I wonder which
>> technical standards would need to be modified to encourage uptake of this
>> option by more manufacturers? I can look into that, as I am involved with
>> Let’s keep in touch fellas, and thanks again

>> along with smartphones, tablets, and computers. Digital video streaming
>> services like iTunes and Netflix that support DV, are designed to only

>> cable, and satellite services might work well. You could use one set to
>> access the audio description track, plugging a headset so that you’re the
>> only one receiving the descriptions. The other TV would provide the main
>> audio and video for everyone else.
>> > For physical media (DVD, etc) and internet streaming, the above
>> solution may be hit-or-miss due to a syncing problem.
>> > For example, you could employ two DVD players, setting one player to
>> the audio description track, and the other player to the main audio track.
>> You'll need to simultaneously (or nearly so) press the play buttons of both
>> players. It may take several tries to get it right (or not). If you get
>> that far, you may have to forgo attempting to simultaneously press the
>> pause buttons of each device for the duration of the video, e.g., no food
>> and bathroom runs :) .
>> > Web streaming services like Netflix are another possibility, but in
>> addition to getting the syncing right, internet bandwidth issues could make
>> synchronizing impossible. If this could actually would, the potential
>> useful part is that your smartphone could serve as the audio description
>> > I’m not recommending “human syncing”, but it could be an interesting

>> Netflix’s uncaptioned second season of Torchwood where I was able to
>> download subtitles to these episodes from a large web repository of
>> subtitles. Using Quicktime 7 and CapScribe, a caption editor, I was able to
>> create a Quicktime movie from just the captions. The final step was to to
>> manually sync the show with the caption video. For caption viewing I used
>> an iPad just under the video. It’s obviously not a very practical solution
>> and it is time consuming. Fortunately Netflix and iTunes have come a long
>> way and most of their content is captioned today (with descriptions
>> catching up).
>> > David … good idea reaching out to AMI. It would be also worth talking
>> with the NCAM folks (NCAM is National Centre for Accessible Media, part of
>> PBS’ Boston flagship station, WGBH). NCAM was the group that initially
>> brought descriptive video to television (DVS) and movie theatres (MoPix).

>> >> Hi John,
>> >> That makes perfect sense.
>> >> To put a finer point on it,
>> >> I think you want two things happening at once:
>> >> 1 of 2: audio description user (e.g., John) hears the typical track +
>> >> audio description track on bluetooth headset, while...
>> >> 2 of 2: typical users (e.g., rest of John's family) hears the typical
>> >> only, via the loudspeakers.
>> >> I am not aware if this has been done, however I'm thinking our friends
>> >> AMI should know (and/or can "make it so").
>> >> Would you like me to query them on it?
>> >> Regards,
>> >> David

>> >>> Hi everyone, I’ve had this question on my mind for some time and
>> >>> you might know the answer – has anyone yet invented away for the
>> >>> video from movies and television to be encapsulated it up Bluetooth
>> >>> So that the rest of my family did not listen to it?
>> >>> As a blind watcher, this seems very obvious to me, but surely others
>> >>> come up with this idea – has anyone created it?
>> >>> And if it already exists, any thoughts on why it’s not easily
>> >>> through standard smart TVs, and streaming services?
