Michael Karagosian Closed Caption Analysis of 6 Feb 2009

We now have a second closed caption system on the market that utilizes thestandardized CSP/RPL protocol. The new product is from Intelligent Access Systems, led by Leanne West and Ethan Adler.  Leanne is known for her work with Georgia Tech Research Institute. Intelligent Access has volunteered to participate in the ISDCF March demo.

[Editor: The ISDCF March demo is primarily centered on evaluating the changes coming with the change from the InterOp format to the SMPTE format for DCPs. Evaluating caption systems are not the primary goal of the this science-base demo.]

We now have substantial support in digital cinema for accessibility.  Below
is a brief review of the closed caption products on the market.

USL offers a single infrared transmitter solution to provide 2-channel audio
and closed captions into the auditorium.  The transmitter receives CSP/RPL
for closed captions.  The transmitter drives two different closed caption
displays:  a cup-holder-mounted display, and closed caption glasses.  The
transmitter also drives USL’s assistive listening solution, which supports 2
user-selectable channels.

Intelligent Access Systems
Intelligent Access offers a WiFi-driven closed caption solution.  The WiFi
transmitter receives CSP/RPL for closed captions.  The WiFi signal can be
received by Windows Mobile or iPhone/iPod Touch devices connected to closed
caption glasses.

Doremi offers a ZigBee wireless transmitter (similar to Bluetooth) to drive
its cup-holder-mounted closed caption display.  Doremi’s transmitter is
added to the server, and cannot be driven by a CSP/RPL server output.
