HD For Indies

DC28 is the group doing the DCI spec. here's notes on the overview:

DC28

Digital Cinema Technology Committee DC28 Wendy Aylsworth - Chair

It's not quite done yet, it'll be a long time before it's mature (and implied, stable and reliable)

DC28 charter to make engineering docs
Three working groups:

mastering
distribution
exhibition

standards authoring kicked in hard at this point

probably about 35 documents foreseen, 24 in progress at the moment

others in drafting format in ad hoc groups

1 is ready for publication

4 are going to draft standard ballot

8 are in final committee draft cycle

5 in committee draft cycle (1st ballot for everyone to comment on it)


MASTERING - making the DSM

DISTRIBUTION - prep for compression, encrypion

Exhibition - key Mgmt, forensics, certificates, mesaging

(note how much attention is being spent on tracking...FAR beyond what is done now)

when mastering, there will be specs for exhibition screen luminance, chrominance, and conformity

NO OFFENSE TO WENDY, BUT THIS IS ALL ABOUT WHAT DOCUMENTS THEY ARE GOING TO CREATE...UNLESS YOU'RE HUGELY INVOLVED, I DON'T THINK THIS IS TERRIBLY INTERESTING. NECESSARY, BUT NOT INTERESTING.

MXF J2K CONSTRAINTS - OK, this'll be interesting

Operational constraints - all the things to worry about as you make this stuff

clearly they intend1 1 Gigabit/sec networking, as they reference 1 Gb/sec link encryption

SMPTE N26 Dual link 1.5Gb/sec interface...so is this dual link HD-SDI or something else? Encrypted link between projector and server

FOUR TUTORIALS TODAY -

1.) X'Y'Z' Color Encoding
2.) security architecture
3.) JPEG2000 compression
4.) packaging for distribution

15 key standards will be published in 2005...it takes a long time to get stuff balloted, commented, and approved after writing stuff.

SMPTE is unique in that it's not driven by corporations and nations, it's driven by the engineers
