Following an ethical firestorm and several lawsuits, movie theatres finally showed a greater desire to implement a technology that would provide subtitles for the hearing-impaired, while maintaining the viewing experience for the general audience. Several technologies, including the Rear Window Captioning System co-developed by the Media Access Group and Rufus Seder, have been tested since then, but none fit the preferred cost and efficiency requirements put forth by the movie theatres. DVD Genesis addresses these requirements by extracting subtitles from a PC’s DVD player. The subtitles are then sent to an external display that can be mounted inside a seat’s cup-holder or on its armrest. The display’s arm can then be adjusted to position the display in the user’s line of sight and at the bottom of the movie screen, giving the appearance of superimposed subtitles. Research shows that by 2010 most movie theatres will have transitioned to digital media (MPEG-2), making DVD Genesis an extremely powerful solution for this environment. Additionally, DVD Genesis’ unique, low-cost design and user-friendly interface also make it suitable for other environments. Methods Serial RS232/TTL Matrix Orbital LCD – LK404-25 Bluetooth Virtual COM Ports - AIRcable Serial3 Parsing the .SRT File Start Time End Time Subtitle number Synchronization of Subtitles with Video • In order to synchronize the subtitles with the video, VLC Media Player’s source code is modified to output the movie’s running time to a text file. • This time is then read by the DVD Genesis software, which integrates it with the information from the parsed .SRT file to handle the display and clearing of the subtitles from the screen. Timestamps Subtitle • In order to transmit subtitles to an external display, DVD Genesis first converts the subtitles (stored as graphical bitmaps on DVDs) to a text format (.SRT) using SubRip (an Optical Character Recognition software). • It then stores a pointer to the subtitle in an array according to its subtitle number and timestamp. • Each pointer then links to elements in two separate arrays that hold the milliseconds of the timestamp and the duration (End Time – Start Time) of the subtitle.
