SMPTE working groups 21DC-10 Mastering and 21DC-30 Exhibition met mid-February. Changes were proposed to 430-6 Auditorium Security Messages (ASM) by DCI consultant Tony Wechselberger and TI Director of DLP Cinema Technology Reiner Doetzkies. The standard, which is less than a year old, describes the process of establishing a secure TLS session across a network for communication of security certificate information. It was said in the meeting that the proposal would break current installations. Unfortunately, neither proponent attended the meeting to present the proposed changes, which may have led to misinterpretations. The discussion will continue on March 5 at the quarterly 21DC Technology Committee plenary meeting.
On the closed caption front, it appears that the Content Synchronization Protocol and Resource Presentation List (CSP/RPL) work is stabilizing. USL, GDC, and Kodak are known to be working on implementations. To facilitate testing, Disney volunteered copies of its movie Game Plan. Brad Botkin of WGBH also made available, with Disney’s permission, a SMPTE closed caption file for the movie. Cinecert donated personnel and facilities to create the SMPTE-compliant package. This is the first known complete test material for SMPTE closed captions to become available.
