| It is conceptually very similar to DTS-CSS. started in 2003, closed caption track.ased around an off-the-shelf PC, Dolby ScreenTalk superimposes subtitles over the main picture, using either a customer-supplied video projector or the cinema's existing video projector. the ScreenTalk superimposes subtitles over the projected image using a video projector, or displays the text via an alternative subtitling device. There is no need for special prints; the film distributor simply provides the cinema, either electronically or via CD-ROM, a computer file containing the subtitling and audio description information for a particular release. The Dolby ScreenTalk system can also be used with a video projector to exhibit advertising slide shows. Cinema staff can assemble and load the shows using Dolby ST Media software supplied with the ScreenTalk package. For audience members with disabilities, the system interfaces with the cinema’s wireless headphone installation to transmit audio commentary directly to visually impaired patrons. Subtitles for the hearing impaired can be projected simultaneously, using a different color for each character’s dialogue
The ScreenTalk system operates in conjunction with a PC running Linux Dolby software. Projectionist control is provided by the Dolby Model ST100 System Controller, Timing information from the film’s Dolby Digital soundtrack links the subtitles and audio description to the film being shown. The Dolby ScreenTalk package also includes an electronically controlled douser (Dolby Cat. No. 765A), which is positioned in front of the video projector.
basically, you have to subcontract a captioning agency to do the format of the catpion required. ( single color, multicolor, with or without description service, etc ) they do the captioning and deliver a file to you to be delivered to Dolby. ( or DTS for DTS-CSS )... Also a creative ( director / producer ) needs to be involved to review and approve the closed captioned data and formats ) Once the production is ready to be captioned, the necessary work materials (Guide Image and final script) must be provided to the captioning agency. Each licensed captioning agency will have a preference in regard to format or delivery of the Guide Image (ie Digital Betacam, DVD, FTP etc). Check with your preferred agency for this information. T
The captioning agency creates the caption file and/or audio description file. This file(s) will be forwarded to your DVD authoring house or to DOLBY / DTS.... the materials include image, script, In/out timecodes for reels, video, etc...
Here's an overview of delivery specs I had in ym research library.
Captioning agency image delivery requirements
All deliverables to a captioning agency must be in accordance with the ‘Captioning
agency’ sections in the Captioning Process for Cinema and DVD pages.
Preferred image format is a low res MPEG 1 file but will accept:
•
– Digital Betacam
– MPEG 2
– QuickTime
– Betacam SP
– DVD
– DV
* Preferred script format is via email.
Digital Betacam transfer of consecutive film reels with burnt in timecode to match
•
the reels:
– For film delivery the Digital Betacam must run at appropriate frame rate for project, with burnt in
timecode.
The Captioning Studio
The Captioning Studio require delivery of:
Windows Media Video file or an MPEG 1 file or a DVD with in-vision timecode
•
matching the DTS timecode.

Guide to Cinema Captioning
If this is unavailable DVDTech can accept a Digital Betacam with a timecode that
•
matches the DTS timecode.
* Electronic script if available.
POST-PRODUCTION SCRIPTS
Productions will need to provide the caption agency with the song title and artist
information. This could be included in the post-production script within the ‘shot
description’ column and should outline where the songs are used in the film. This
information should be provided to the person generating the post-production script.
Captioning agencies would also prefer to receive the post-production script as an
Excel or Word document rather than a PDF.
I thought the Dolby Screentalk was discontinued a year or so ago....( at least in the states ) i'd check with your client to assure you really have to deliver, or if the request is just stillin the spec but actually not required. ( side note: I think Lord of the rings was released with Screentalk in the UK ) so I may be blowing smoke here.
cheers
